The patients were divided into two groups to undergo digestive tract construction using either IJOM after TLTG(group T, n = 51) or Roux-en-Y anastomosis after laparoscopic-assisted total gastrectomy(LATG)(group A, n = 456). The short-term outcomes and Qo L were compared between the two groups after 1:2 propensity-score matching(PSM). We used a questionnaire to assess Qo L.RESULTS Before matching, age, sex, tumor size, tumor location, preoperative albumin and blood loss were significantly different between the two groups(P < 0.05). After PSM, the patients were well balanced in terms of their clinicopathological characteristics, although both blood loss and in-hospital postoperative days in group T were significantly lower than those in group A(P < 0.05). After matching, group T reported better Qo L in the domains of pain and dysphagia. Among the items evaluating pain and dysphagia, group T tended to report better Qo L("Have you felt pain" and "Have you had difficulty eating solid food")(P < 0.05).CONCLUSION The IJOM for digestive tract reconstruction after TLTG is associated with reduced blood loss and less pain and dysphagia, thus improving Qo L after laparoscopic gastrectomy.展开更多

Basic characteristics of patients, surgical and clinical outcomes were reported. The technique for reconstruction (Parisi Technique) consists on a loop of bowel shifted up antecolic to directly perform the esophago-enteric anastomosis followed by a second loop, measured up to 40 cm starting from the esojejunostomy, fixed to the biliary limb to create an enteroenteric anastomosis. The continuity between the two anastomoses is interrupted just firing a linear stapler, so obtaining the Roux-en-Y by avoiding to interrupt the mesentery.RESULTSFifty-five patients were considered in the present analysis. Estimated blood loss was 126.55 ± 73 mL, no conversions to open surgery occurred, R0 resections were obtained in all cases. Hospital stay was 5 (3-17) d, no anastomotic leakage occurred. Overall, a fast functional recovery was shown with a median of 3 (3-6) d in starting a solid diet.CONCLUSIONRobotic surgery and the adoption of a tailored reconstruction technique have increased the feasibility and safety of a minimally invasive approach for total gastrectomy. The present series of patients shows its implementation in a western center with satisfying short-term outcomes.展开更多

This study aims to analyze the safety and feasibility of LTG after PT for GC/GEJC patients.Methods: We retrospectively analyzed the data of 511 patients with GC/GEJC undergoing LTG, of which 405received LTG(LTG group) and 106 received PT+LTG(PT-LTG group) at Nanfang Hospital between June 2018and September 2022. The surgical outcomes were compared between the two groups.Results: The surgical duration was significantly longer in the PT-LTG group(P<0.001), while the incidence of intraoperative complications(P=1.000), postoperative complications(LTG group vs. PT-LTG group: 26.2% vs.23.6%, P=0.587), the classification of complication severity(P=0.271), and postoperative recovery was similar between two groups. Notably, the incidence of anastomotic complications of esophagojejunostomy was also comparable between the two groups(LTG group vs. PT-LTG group: 5.9% vs. 5.7%, P=0.918). The univariate and multivariate analysis confirmed that positive proximal margin [positive vs. negative: odds ratio(OR)=14.094, 95%confidence interval(95% CI): 2.639-75.260, P=0.002], rather than PT, has an impact on anastomotic complications after LTG(OR=0.945, 95% CI: 0.371-2.408, P=0.905).Conclusions: PT did not increase the surgical risk of LTG for GC/GEJC. Therefore, considering the positive effect of PT on long-term survival, the broader application of PT and LTG for GC/GEJC is supported by our findings.展开更多

The aim of this self- controlled study was to examine the effect of jejunostomy tube feeding （JTF） and other factors on postoperative weight and the incidence of jejunostomy-related complications in patients undergoing total gastrectomy for cancer. Methods： All consecutive patients who underwent total gastrectomy for gastric cancer with jejunostomy plaeement were included from a prospective single-center database （2003-2014）. Jejunostomy-related complications and postoperative weight changes were evaluated up to 12 months after surgery. Multivariable linear regression analysis was performed to identify factors associated with weight loss 12 months after gastreetomy. Results： Of 113 patients operated in the study period, 65 received JTF after total gastrectomy for a median duration of 18 d [interquartile range （IQR）, 10-55 d]. Jejunostomy-related complieations occurred in 11 （17%） patients, including skin leakage （n=3） and peritoneal leakage （n=2）, luxation （n=3）, occlusion （n=2）, infection （n=l） and torsion （n=l）. In 2 （3%） patients, a reoperation was needed due to jejtmostomy-related complications. The mean preoperative weight of patients was 71.8 kg （100%）, and remained stable during JTF （73.9 kg, 103%, P=0.331）. After JTF was stopped, the mean weight of patients decreased to 64.9 kg （90%） at 12 months after surgery （P〈0.001）. A high preoperative body mass index （BMI） （〉_25 kg/m2） was associated with high postoperative weight loss compared to patients with a low BMI （〈25 kg/m2） （16.3% vs. 8.6%, P=0.016）. Conclusions： JTF can prevent weight loss in the early postoperative phase. However, this is at the prize of possible complications. As weight loss in the long term is not prevented, routine JTF should be re-evaluated and balanced against the selected use in preoperatively malnourished patients. Special attention should be paid to patients with a high preoperative BMI, who are at risk of more postoperative weight loss.展开更多

There is still no consensus on the best reconstruction technique. The aim of this report was to derive a more precise estimation of Roux-en-Y esophagojejunostomy with a pouch compared with Roux-en-Y esophagojejunostomy without a pouch. Studies were identified by PubMed and Embase searches, and the inclusion criteria were randomized controlled trials （RCTs） comparing reconstruction techniques between Roux-en-Y with and without a pouch. A total of 12 studies including 1,018 patients were included. The meta-analysis shows that pouch Roux-en-Y does not significantly increase total postoperative complications, anastomotic leakage or mortality, hnportantly, there is no significant difference in S-year survival rates between the two groups. Patients with Roux-en-Y esophagojejunostomy complained significantly less of reflux symptoms and dumping syndrome, and had significantly less severe reflux esophagitis. Quality of life was significantly improved in patients with Roux-en-Y esophagojejunostomy with a pouch compared with patients who received Roux-en-Y reconstruction without a pouch. The results indicate the need for Roux-en-Y esophagojeju- nostomy with a pouch is a gastric substitute after total gastrectomy by comparison with Roux-en-Y esophagojejunostomy without a pouch.展开更多
文摘BACKGROUND Esophagojejunal anastomotic leakage(EJAL)is a severe complication following gastrectomy for gastric cancer,typically treated with drainage and nutritional support.We report a case of intraluminal drain migration near the esophagojejunal anastomosis(EJA),resulting in persistent drainage and mimicking EJAL after total gastrectomy.CASE SUMMARY A 64-year-old male underwent open total gastrectomy with Roux-en-Y reconstruction for gastric adenocarcinoma,with two silicone drains placed near the EJA.On postoperative day(POD)4,the patient developed signs of peritonitis and sepsis,necessitating surgical re-exploration abscess drainage,peritoneal lavage,and drain repositioning.A contrast swallow study on POD 18 revealed rapid filling of the abdominal drain without extraluminal contrast collection.Persistent drainage prompted an upper gastrointestinal endoscopy on POD 59,which revealed approximately 5 cm of the drain within the esophagus,with the perforation site located 2 cm distal to the intact EJA.The drain was repositioned under endoscopic guidance.A repeat contrast radiograph on POD 67 demonstrated no evidence of extraluminal contrast extravasation or filling of the abdominal drain.The patient was subsequently discharged without further incident.CONCLUSION Intraluminal drain migration is a rare complication following gastric surgery but should be considered when persistent drainage occurs.
文摘BACKGROUND For patients with advanced gastric cancer,surgical resection remains the main treatment option.Total gastrectomy combined with radical resection of gastric cancer lesions and sentinel lymph nodes can significantly prolong the survival of patients.Digestive tract reconstruction after total gastrectomy is essential to maintain gastrointestinal function and optimize postoperative recovery.Therefore,it is very important to choose a suitable reconstruction method to improve the quality of life of total gastrectomy patients.AIM To evaluate the effects of different digestive tract reconstruction methods in gastric cancer patients undergoing total gastrectomy.METHODS This retrospective study included 172 patients who underwent total gastrectomy for gastric cancer at The First Hospital of Hebei Medical University for analysis.The patients were categorized into two groups:Group A,consisting of 90 patients who underwent modified Roux-en-Y gastrojejunostomy,and group B,consisting of 82 patients who underwent uncut Roux-en-Y gastrojejunostomy.The general patient characteristics,perioperative indicators,postoperative gastrointestinal mucosal barrier function,nutritional status,immunological markers,and occurrence of complications were compared between the two groups.RESULTS Group A showed shorter digestive tract reconstruction time than group B(P<0.05).On the first postoperative day,group A showed lower serum levels of D-lactate,diamine oxidase,and endotoxin than group B(P<0.05).One month postoperatively,group A showed higher prognostic nutritional index,serum albumin,total protein,and body weight than group B(P<0.05).One month postoperatively,the levels of cluster of differentiation(CD)3+,CD4+,and CD8+cells were not significantly different between two groups(P>0.05).The complication rates were 10.00%in group A and 24.39%in group B;group A had a significantly lower complication rate than group B(P<0.05).CONCLUSION Using modified Roux-en-Y gastrojejunostomy during total gastrectomy shortens the time required for gastrointestinal anastomosis,reduces surgery-induced gastrointestinal mucosal damage,and mitigates postoperative declines in nutritional status.

文摘BACKGROUND Gastric cancer(GC)is a major global health challenge,and the treatment of proximal GC in particular presents unique clinical and surgical complexities.Currently,there is no consensus on whether proximal gastrectomy(PG)or total gastrectomy(TG)should be used for advanced proximal GC,and the choice of postoperative gastrointestinal reconstruction method remains controversial.AIM To compare the short-term efficacy,long-term survival,and postoperative reflux outcomes of PG with tubular stomach reconstruction vs TG with Roux-en-Y re-construction in patients with proximal GC following neoadjuvant chemotherapy(NACT)in an effort to provide valuable insights for clinical decision-making regarding the optimal surgical approach.METHODS A multicenter retrospective cohort study was conducted at two Chinese medical centers between December,2012 and December,2022.Patients with histologically confirmed proximal GC who received NACT followed by either PG with tubular stomach reconstruction or TG with Roux-en-Y reconstruction were included.Propensity score matching(PSM)was performed to balance baseline characteristics,and the primary endpoint was 5-year overall survival(OS).Se-condary endpoints included recurrence-free survival(RFS),postoperative complications,and reflux severity.RESULTS After PSM,244 patients(122 PG,122 TG)were finally included and all baseline characteristics were comparable between groups.The PG group had a significantly shorter operation time compared to the TG group(189.50 vs 215.00 minutes,P<0.001),with no differences in intraoperative blood loss or postoperative complications(19.68%vs 14.75%,P=0.792).The 5-year OS rates were 52.7%vs 45.5%(P=0.330),and 5-year RFS rates were 54.3%vs 47.6%(P=0.356)for the PG and TG groups,respectively.Reflux symptoms(18.0%vs 31.1%,P=0.017)and clinically significant reflux based on gastroesophageal reflux disease questionnaire scores≥8(7.4%vs 21.3%,P<0.001)were significantly less frequent in the PG group.Multivariate analysis identified histological differentiation(HR=2.98,95%CI:2.03-4.36,P<0.001)and tumor size(HR=0.26,95%CI:0.17-0.41 for tumors≤4 cm,P<0.001)as independent prognostic factors.CONCLUSION PG with tubular stomach reconstruction is comparable to TG in terms of surgical safety and long-term oncological outcomes for proximal GC patients following NACT.Additionally,PG has the advantages of shorter operation time and lower rates of postoperative reflux,suggesting potential benefits for patient quality of life.Notably,the analysis of postoperative prognostic factors,including histological differentiation and tumor size,further informs clinical decision-making and highlights the importance of individualized treatment strategies.
文摘BACKGROUND Petersen’s hernia occurring through the epiploic foramen of the greater omentum,is an uncommon type of internal hernia.When it presents with complications such as chylous ascites,which is the lymphatic fluid accumulation in the abdominal cavity,it is particularly rare.Following laparoscopic total gastrectomy and Roux-en-Y anastomosis,the incidence of this condition is exceedingly low.CASE SUMMARY A 62-year-old male patient developed Petersen’s hernia following laparoscopic total gastrectomy(LTG)for gastric cancer,after Roux-en-Y anastomosis.Intestinal torsion and obstruction were experienced by the patient,along with a small amount of chylous ascites.Imaging studies and clinical assessment confirmed the diagnosis.Emergency surgery was performed promptly for the patient in the operating room.The twisted small intestine was reduced and the defect in Petersen’s space was repaired.The procedure was successful in the correction of the intestinal torsion and approximation of the hernia without the need for bowel resection.The patient’s condition significantly improved following the surgery.The ascites evolved from a milky white appearance to a pale yellow,with a substantial decrease in the triglyceride levels in the ascitic fluid,implying a favorable recovery trajectory.The patient was monitored closely and received appropriate care postoperatively,including nutritional support and fluid management.CONCLUSION This report illustrates the significance of recognizing Petersen’s hernia as a potential complication following gastrectomy for gastric cancer.It highlights the fundamental role of early surgical intervention in the effective management of such complications.The favorable outcome in this patient illustrates that prompt and appropriate surgical management can deter the necessity for more extensive procedures such as bowel resection.
文摘BACKGROUND At present,the concept of surgical treatment of gastric cancer(GC)has changed from“radical treatment”to“care for patients”to a certain extent.The reconstruction method is the most likely to affect the postoperative life of the patient.Currently,the traditional Roux-en-Y esophagojejunostomy anastomosis is a commonly used method for gastrointestinal reconstruction after total gastrectomy for GC.However,more recent studies have shown that the traditional Roux-en-Y anastomosis is complicated in operation procedure,with more reconstruction steps and longer reconstruction time,and the incidence of postoperative complications such as adhesive intestinal obstruction,internal abdominal hernia and volvulus is high.Moreover,the incidence of Roux stasis syndrome is 10%-30%after traditional Roux-en-Y reconstruction.Thus,we modified the traditional Roux-en-Y alimentary tract reconstruction,and designed a new digestive tract reconstruction method for laparoscopy-assisted Roux-en-Y anastomosis for total gastrectomy of GC.AIM To evaluate the clinical advantages,feasibility,and safety of a modified Roux-en-Y digestive tract reconstruction in laparoscopy-assisted total gastrectomy for the treatment of GC compared with the traditional Roux-en-Y method.METHODS Ninety-seven patients who underwent laparoscopy-assisted D2 radical gastrectomy(total gastrectomy)for GC were divided into two groups:fifty-four in the conventional Roux-en-Y reconstruction group(Orr group)and forty-three in the modified Roux-en-Y reconstruction group(the modified group).Perioperative and short-term outcomes were analyzed,including complications,postoperative weight loss,hemoglobin levels,and nutritional status.RESULTS The Orr group and the modified group showed no statistically significant differences in baseline characteristics.Compared with the Orr group,the modified group had shorter digestive tract reconstruction and operation times,less intraoperative bleeding,and shorter postoperative hospital stays compared to the Orr group.Although both groups had similar amounts of intraoperative blood loss,postoperative recovery times,and hospital expenses,the Orr group experienced longer operation times and digestive tract reconstruction times.Furthermore,the modified Roux-en-Y group demonstrated significantly fewer short-term and long-term complications,with a reduced incidence of reflux esophagitis and improved nutritional status.CONCLUSION The modified Roux-en-Y digestive tract reconstruction method after laparoscopy-assisted total gastrectomy for GC offers safety,simplicity,and a reduction in bile reflux.This method shortens operation times and minimizes postoperative complications,aligns with modern rapid rehabilitation surgery trends and potentially improves patient prognosis and overall survival.This method warrants further clinical application and promotion.
文摘BACKGROUND Natural orifice specimen extraction surgery(NOSES)has emerged as a promising alternative compared to conventional laparoscopic-assisted total gastrectomy(LATG)for treating gastric cancer(GC).However,evidence regarding the efficacy and safety of NOSES for GC surgery is limited.This study aimed to compare the safety and feasibility,in addition to postoperative complications of NOSES and LATG.METHODS Dual circular staplers were used in Roux-en-Y digestive tract reconstruction for transvaginal specimen extraction LATG,and its outcomes were compared with LATG in a cohort of 51 GC patients with tumor size≤5 cm.The study was conducted from May 2018 to September 2020,and patients were categorized into the NOSES group(n=22)and LATG group(n=29).Perioperative parameters were compared and analyzed,including patient and tumor characteristics,postoperative outcomes,and anastomosis-related complications,postoperative hospital stay,the length of abdominal incision,difference in tumor type,postoperative complications,and postoperative survival.RESULTS Postoperative exhaust time,operation duration,mean postoperative hospital stay,length of abdominal incision,number of specific staplers used,and Brief Illness Perception Questionnaire score were significant in both groups(P<0.01).In the NOSES group,the postoperative time to first flatus,mean postoperative hospital stay,and length of abdominal incision were significantly shorter than those in the LATG group.Patients in the NOSES group had faster postoperative recovery,and achieved abdominal minimally invasive incision that met aesthetic requirements.There were no significant differences in gender,age,tumor type,postoperative complications,and postoperative survival between the two groups.CONCLUSION The application of dual circular staplers in Roux-en-Y digestive tract reconstruction combined with NOSES gastrectomy is safe and convenient.This approach offers better short-term outcomes compared to LATG,while long-term survival rates are comparable to those of conventional laparoscopic surgery.
文摘BACKGROUND The development of laparoscopic technology has provided a new choice for surgery of gastric cancer(GC),but the advantages and disadvantages of laparoscopic total gastrectomy(LTG)and laparoscopic-assisted total gastrectomy(LATG)in treatment effect and safety are still controversial.The purpose of this study is to compare the efficacy and safety of the two methods in the treatment of GC,and to provide a basis for clinical decision-making.AIM To compare the efficacy of totally LTG(TLTG)and LATG in the context of radical gastrectomy for GC.Additionally,we investigated the safety and feasibility of the total laparoscopic esophagojejunostomy technique.METHODS Literature on comparative studies of the above two surgical methods for GC(TLTG group and LATG group)published before September 2022 were searched in the PubMed,Web of Science,Wanfang Database,CNKI,and other Chinese and English databases.In addition,the following search keywords were used:Gastric cancer,total gastrectomy,total laparoscopy,laparoscopy-assisted,esophagojejunal anastomosis,gastric/stomach cancer,total gastrectomy,totally/completely laparoscopic,laparoscopic assisted/laparoscopy assisted/laparoscopically assisted,and esophagojejunostomy/esophagojejunal anastomosis.Review Manager 5.3 software was used for the meta-analysis after two researchers independently screened the literature,extracted the data,and evaluated the risk of bias in the included studies.RESULTS After layer-by-layer screening,258 pieces of literature were recovered,and 11 of those pieces were eventually included.This resulted in a sample size of 2421 instances,with 1115 cases falling into the TLTG group and 1306 cases into the LATG group.Age or sex differences between the two groups were not statistically significant,according to the meta-analysis,however the average body mass index of the TLTG group was considerably higher than that of the LATG group(P=0.01).Compared with those in the LATG group,the incision length in the TLTG group was significantly shorter(P<0.001),the amount of intraoperative blood loss was significantly lower(P=0.003),the number of lymph nodes removed was significantly greater(P=0.04),and the time of first postoperative feeding and postoperative hospitalization were also significantly shorter(P=0.03 and 0.02,respectively).There were no significant differences in tumor size,length of proximal incisal margin,total operation time,anastomotic time,postoperative pain score,postoperative anal exhaust time,postoperative anastomosis-related complications(including anastomotic fistula,anastomotic stenosis,and anastomotic hemorrhage),or overall postoperative complication rate(P>0.05).CONCLUSION TLTG and esophagojejunostomy are safe and feasible.Compared with LATG,TLTG has the advantages of less trauma,less bleeding,easier access to lymph nodes,and faster postoperative recovery,and TLTG is also suitable for obese patients.
文摘Objective:To investigate the clinical application effect of laparoscopic-assisted total gastrectomy in the surgical treatment of gastric cancer.Methods:The clinical data of 86 COPD patients included in the study were collected and divided into 43 cases each in Groups A and B using the randomization method,with open total gastrectomy in Group A and laparoscopic-assisted total gastrectomy in Group B.The clinical indexes,pain levels,and complications of patients in the two groups were observed in combination with the indexes.Results:The baseline data of the two groups of patients were not statistically significant(all P>0.05);the operation time,incision length,first flatulence time,and hospitalization time of patients in Group B were shorter than those in Group A(all P=0.000);the NRS scores of patients in Group B on the 1st postoperative day and the 2nd postoperative day were significantly lower than those in Group A(t=23.443,t=28.784,all P=0.000);the total complication rate of patients in Group B(1;2.33%)was significantly lower than that of Group A(9;20.94%)(χ^(2)=7.242,P=0.007).Conclusion:In the surgical treatment of gastric cancer,laparoscopic-assisted total gastrectomy can promote patients’recovery,reduce patients’pain,and lower the probability of complications.

文摘BACKGROUND Laparoscopic total gastrectomy(LTG)has drawn increasing attention over the years.Although LTG has shown surgical benefits compared to open TG(OTG)in early stage gastric cancer(GC),little is known about the surgical and oncological outcomes of LTG for advanced GC following neoadjuvant therapy(NAT).AIM To compare the long-and short-term outcomes of advanced GC patients who underwent LTG vs OTG following NAT.METHODS Advanced GC patients who underwent TG following NAT between April 2011 and May 2018 at the Cancer Hospital of the Chinese Academy of Medical Sciences were enrolled and stratified into two groups:LTG and OTG.Propensity score matching analysis was performed at a 1:1 ratio to overcome possible bias.RESULTS In total,185 patients were enrolled(LTG:78;OTG:109).Of these,138 were paired after propensity score matching.After adjustment for propensity score matching,baseline parameters were similar between the two groups.Compared to OTG,LTG was associated with a significantly shorter length of hospital stay(P=0.012).The rates of R0 resection,lymph node harvest,and postoperative morbidity did not significantly differ between the two groups.Overall survival(OS)outcomes were comparable between the two groups.Pathological T and N stages were found to be independent risk factors for OS.CONCLUSION LTG can be a feasible method for advanced GC patients following NAT,as it appears to be associated with better short-and comparable long-term outcomes compared to OTG.
文摘Objective:To investigate the effect and complication rate of totally laparoscopic and laparoscopic-assisted total gastrectomy in the treatment of gastric cancer.Methods:From March 2019 to July 2021,60 patients with gastric cancer were selected as the subjects in this study;the patients in group A underwent laparoscopic-assisted total gastrectomy,whereas those in group B underwent totally laparoscopic total gastrectomy;the treatment effect and complication rate were compared between the two groups.Results:The postoperative recovery of group B was significantly better than that of group A,and the postoperative complications(10.00%)of group B were significantly lower than that of group A(33.33%)(P<0.05).Conclusion:For patients with gastric cancer,totally laparoscopic total gastrectomy has better therapeutic effect and lower postoperative complications,which is worthy of popularization.

文摘AIM To evaluate the short-term outcomes and quality of life(Qo L) in gastric cancer patients undergoing digestive tract construction using the isoperistaltic jejunum-latercut overlap method(IJOM) after totally laparoscopic total gastrectomy(TLTG).METHODS A total of 507 patients who underwent laparoscopic gastrectomy(D2) from January 2014 to March 2016 were originally included in the study. The patients were divided into two groups to undergo digestive tract construction using either IJOM after TLTG(group T, n = 51) or Roux-en-Y anastomosis after laparoscopic-assisted total gastrectomy(LATG)(group A, n = 456). The short-term outcomes and Qo L were compared between the two groups after 1:2 propensity-score matching(PSM). We used a questionnaire to assess Qo L.RESULTS Before matching, age, sex, tumor size, tumor location, preoperative albumin and blood loss were significantly different between the two groups(P < 0.05). After PSM, the patients were well balanced in terms of their clinicopathological characteristics, although both blood loss and in-hospital postoperative days in group T were significantly lower than those in group A(P < 0.05). After matching, group T reported better Qo L in the domains of pain and dysphagia. Among the items evaluating pain and dysphagia, group T tended to report better Qo L("Have you felt pain" and "Have you had difficulty eating solid food")(P < 0.05).CONCLUSION The IJOM for digestive tract reconstruction after TLTG is associated with reduced blood loss and less pain and dysphagia, thus improving Qo L after laparoscopic gastrectomy.

文摘BACKGROUND Although several methods of totally laparoscopic total gastrectomy(TLTG)have been reported.The best anastomosis technique for LTG has not been established.AIM To investigate the effectiveness and surgical outcomes of TLTG using the modified overlap method compared with open total gastrectomy(OTG)using the circular stapled method.METHODS We performed 151 and 131 surgeries using TLTG with the modified overlap method and OTG for gastric cancer between March 2012 and December 2018.Surgical and oncological outcomes were compared between groups using propensity score matching.In addition,we analyzed the risk factors associated with postoperative complications.RESULTS Patients who underwent TLTG were discharged earlier than those who underwent OTG[TLTG(9.62±5.32)vs OTG(13.51±10.67),P<0.05].Time to first flatus and soft diet were significantly shorter in TLTG group.The pain scores at all postoperative periods and administration of opioids were significantly lower in the TLTG group than in the OTG group.No significant difference in early,late and esophagojejunostomy(EJ)-related complications or 5-year recurrence free and overall survival between groups.Multivariate analysis demonstrated that body mass index[odds ratio(OR),1.824;95%confidence interval(CI):1.029-3.234,P=0.040]and American Society of Anaesthesiologists(ASA)score(OR,3.154;95%CI:1.084-9.174,P=0.035)were independent risk factors of early complications.Additionally,age was associated with≥3 Clavien-Dindo classification and EJrelated complications.CONCLUSION Although TLTG with the modified overlap method showed similar complication rate and oncological outcome with OTG,it yields lower pain score,earlier bowel recovery,and discharge.Surgeons should perform total gastrectomy cautiously and delicately in patients with obesity,high ASA scores,and older ages.

文摘AIM： To study the risk factors for morbidity and mortality following total gastrectomy. METHODS： We retrospectively reviewed the records of 125 consecutive patients who underwent total gastrectomy for gastric cancer at the Second Affiliated Hospital of Zhejiang University School of Medicine between January 2003 and March 2008. RESULTS： The overall morbidity rate was 20.8% （27 patients） and the mortality rate was 3.2% （4 patients）. Morbidity rates were higher in patients aged over 60 [odds ratio （OR） 4.23 （95% confidence interval （CI） 1.09 to 12.05）], with preoperative comorbidity [with vs without, OR 1.25 （95% CI 1.13 to 8.12）], when the combined resection was performed [combined resection vs total gastrectomy only, OR 2.67 （95% CI 1.58 to 5.06）]. CONCLUSION： Age, preoperative comorbidity and combined resection were with the rate of morbidity gastric cancer. independently associated after total gastrectomy for
文摘To show outcomes of our series of patients that underwent a total gastrectomy with a robotic approach and highlight the technical details of a proposed solution for the reconstruction phase.METHODSData of gastrectomies performed from May 2014 to October 2016, were extracted and analyzed. Basic characteristics of patients, surgical and clinical outcomes were reported. The technique for reconstruction (Parisi Technique) consists on a loop of bowel shifted up antecolic to directly perform the esophago-enteric anastomosis followed by a second loop, measured up to 40 cm starting from the esojejunostomy, fixed to the biliary limb to create an enteroenteric anastomosis. The continuity between the two anastomoses is interrupted just firing a linear stapler, so obtaining the Roux-en-Y by avoiding to interrupt the mesentery.RESULTSFifty-five patients were considered in the present analysis. Estimated blood loss was 126.55 ± 73 mL, no conversions to open surgery occurred, R0 resections were obtained in all cases. Hospital stay was 5 (3-17) d, no anastomotic leakage occurred. Overall, a fast functional recovery was shown with a median of 3 (3-6) d in starting a solid diet.CONCLUSIONRobotic surgery and the adoption of a tailored reconstruction technique have increased the feasibility and safety of a minimally invasive approach for total gastrectomy. The present series of patients shows its implementation in a western center with satisfying short-term outcomes.

文摘Objective: As laparoscopic surgery is widely applied for primarily treated gastric cancer(GC)/gastroesophageal junction cancer(GEJC) and gains many advantages, the feasibility of laparoscopic total gastrectomy(LTG) for GC/GEJC patients who have received preoperative therapy(PT) has come to the fore. This study aims to analyze the safety and feasibility of LTG after PT for GC/GEJC patients.Methods: We retrospectively analyzed the data of 511 patients with GC/GEJC undergoing LTG, of which 405received LTG(LTG group) and 106 received PT+LTG(PT-LTG group) at Nanfang Hospital between June 2018and September 2022. The surgical outcomes were compared between the two groups.Results: The surgical duration was significantly longer in the PT-LTG group(P<0.001), while the incidence of intraoperative complications(P=1.000), postoperative complications(LTG group vs. PT-LTG group: 26.2% vs.23.6%, P=0.587), the classification of complication severity(P=0.271), and postoperative recovery was similar between two groups. Notably, the incidence of anastomotic complications of esophagojejunostomy was also comparable between the two groups(LTG group vs. PT-LTG group: 5.9% vs. 5.7%, P=0.918). The univariate and multivariate analysis confirmed that positive proximal margin [positive vs. negative: odds ratio(OR)=14.094, 95%confidence interval(95% CI): 2.639-75.260, P=0.002], rather than PT, has an impact on anastomotic complications after LTG(OR=0.945, 95% CI: 0.371-2.408, P=0.905).Conclusions: PT did not increase the surgical risk of LTG for GC/GEJC. Therefore, considering the positive effect of PT on long-term survival, the broader application of PT and LTG for GC/GEJC is supported by our findings.

文摘The potential survival benefit of neoadjuvant chemotherapy(NC)in patients with advanced gastric cancer has been widely recognized.With the development of minimally invasive surgery,which is represented by laparoscopy,the effect of NC on the safety of laparoscopic gastrectomy remains to be further explored.AIM To compare the short-term outcomes of laparoscopic total gastrectomy(LTG)after NC(NC-LTG)with LTG alone.METHODS A total of 92 patients who underwent NC-LTG and 381 patients who received LTG alone at the Chinese PLA General Hospital between September 2015 and September 2020 were retrospectively included in our study.We used propensityscore matching(PSM)to balance baseline bias.After 1:1 PSM,73 patients were included in each group with no statistically significant difference in baseline characteristics.RESULTS The NC-LTG group exhibited a longer operation time(244.10±48.13 min vs 225.74±45.33 min,P=0.019)and increased intraoperative blood loss[150(100-300)mL vs 100(100-200)mL,P=0.011]compared to the LTG group.The 30-d postoperative morbidity of the NC-LTG group was 20.5%(15/73),and that of the LTG group was 13.7%(10/73).There were no significant differences in 30-d severe complication rates or anastomotic leakage rates.Subgroup analysis showed that the patients with pTNM(pathological tumor-node-metastasis classification)T0N0-II in the NC-LTG group underwent a longer operation than the LTG group,while no significant difference was found in any perioperative index for the pTNM III patients.A multivariate analysis showed that an operation time longer than 240 min was an independent risk factor(odds ratio=3.021,95%confidence interval:1.160-7.868,P=0.024),while NC was not an independent risk factor for postoperative complications in LTG.CONCLUSION Despite a longer operation time and more blood loss after NC-LTG,which indicate surgical difficulty,NC-LTG exhibits acceptable short-term outcomes compared to LTG,suggesting the safety and feasibility of NC-LTG.

文摘BACKGROUND Laparoscopic radical gastrectomy is currently the most common surgical approach for gastric cancer.The main difference between totally laparoscopic total gastrectomy(TLTG)and laparoscopic-assisted total gastrectomy(LATG)is the route of digestive tract reconstruction.However,TLTG is currently not widespread as the safety and feasibility of intracorporeal esophagojejunostomy is uncertain.AIM To compare the short-term efficacy of TLTG and LATG for radical gastrectomy of gastric cancer,and to determine the safety and feasibility of intracorporeal esophagojejunostomy.METHODS PubMed,EMBASE,and Web of Science databases were searched for all relevant articles regarding TLTG vs LATG for gastric cancer published up to October 1,2019.Inclusion and exclusion criteria were established.All the basic conditions of patients and important clinical data related to surgery were extracted,and a meta-analysis was performed with RevMan 5.3 software.RESULTS Eight studies involving a total of 1883 cases(869 cases in the TLTG group and 1014 cases in the LATG group)were included.Compared with the LATG group,reduced intraoperative blood loss(weighted mean difference=-35.37,95%CI:-61.69--9.06,P=0.008)and a larger number of retrieved lymph nodes(weighted mean difference=3.11,95%CI:-2.60-12.00,P=0.01)were found in the TLTG group.There were no significant differences in operating time,anastomotic time,tumor size,proximal resection margin length,postoperative pain score,time to first flatus,time to first oral intake,postoperative hospital stay,postoperative anastomosis-related complication rate and overall complication rate between the two groups(P>0.05).CONCLUSION Intracorporeal esophagojejunostomy is safe and feasible.TLTG has the advantages of being minimally invasive,reduced intraoperative blood loss and easier access to lymph nodes compared with LATG.Totally laparoscopic gastrectomy is likely to be the surgical trend for gastric cancer in the future.
文摘Objective： Patients undergoing total gastrectomy for cancer are at risk of malnourishment. The aim of this self- controlled study was to examine the effect of jejunostomy tube feeding （JTF） and other factors on postoperative weight and the incidence of jejunostomy-related complications in patients undergoing total gastrectomy for cancer. Methods： All consecutive patients who underwent total gastrectomy for gastric cancer with jejunostomy plaeement were included from a prospective single-center database （2003-2014）. Jejunostomy-related complications and postoperative weight changes were evaluated up to 12 months after surgery. Multivariable linear regression analysis was performed to identify factors associated with weight loss 12 months after gastreetomy. Results： Of 113 patients operated in the study period, 65 received JTF after total gastrectomy for a median duration of 18 d [interquartile range （IQR）, 10-55 d]. Jejunostomy-related complieations occurred in 11 （17%） patients, including skin leakage （n=3） and peritoneal leakage （n=2）, luxation （n=3）, occlusion （n=2）, infection （n=l） and torsion （n=l）. In 2 （3%） patients, a reoperation was needed due to jejtmostomy-related complications. The mean preoperative weight of patients was 71.8 kg （100%）, and remained stable during JTF （73.9 kg, 103%, P=0.331）. After JTF was stopped, the mean weight of patients decreased to 64.9 kg （90%） at 12 months after surgery （P〈0.001）. A high preoperative body mass index （BMI） （〉_25 kg/m2） was associated with high postoperative weight loss compared to patients with a low BMI （〈25 kg/m2） （16.3% vs. 8.6%, P=0.016）. Conclusions： JTF can prevent weight loss in the early postoperative phase. However, this is at the prize of possible complications. As weight loss in the long term is not prevented, routine JTF should be re-evaluated and balanced against the selected use in preoperatively malnourished patients. Special attention should be paid to patients with a high preoperative BMI, who are at risk of more postoperative weight loss.
文摘After a total resection of the stomach, the continuity of the gastrointestinal tract can be restored either by Rouxen-Y esophagojejunostomy with or without a pouch. There is still no consensus on the best reconstruction technique. The aim of this report was to derive a more precise estimation of Roux-en-Y esophagojejunostomy with a pouch compared with Roux-en-Y esophagojejunostomy without a pouch. Studies were identified by PubMed and Embase searches, and the inclusion criteria were randomized controlled trials （RCTs） comparing reconstruction techniques between Roux-en-Y with and without a pouch. A total of 12 studies including 1,018 patients were included. The meta-analysis shows that pouch Roux-en-Y does not significantly increase total postoperative complications, anastomotic leakage or mortality, hnportantly, there is no significant difference in S-year survival rates between the two groups. Patients with Roux-en-Y esophagojejunostomy complained significantly less of reflux symptoms and dumping syndrome, and had significantly less severe reflux esophagitis. Quality of life was significantly improved in patients with Roux-en-Y esophagojejunostomy with a pouch compared with patients who received Roux-en-Y reconstruction without a pouch. The results indicate the need for Roux-en-Y esophagojeju- nostomy with a pouch is a gastric substitute after total gastrectomy by comparison with Roux-en-Y esophagojejunostomy without a pouch.
