METHOD: Total laparoscopic hysterectomy was performed in 2 patients who had undergone liver transplantation, one for adenomyosis and the other for hysteromyoma. RESULTS: It was safe to create a pneumoperitoneum through the umbilical skinfold even though mild adhesion in the pelvic cavity occurred in one patient. The operative times were 95 and 90 minutes, with blood loss of about 100 and 60 ml, respectively. Oral intake, flatus passage, and ambulation recovered within a day, after the operation. No significant changes in liver function were observed except complication of diarrhea caused by Candida albicans in one patient. CONCLUSIONS: The result of the two patients suggest that total laparoscopic hysterectomy is a safe and effective surgical approach for patients who have undergone liver transplantation.展开更多

Material and Methods: Retrospective data analysis of women who underwent TLH for benign diseases between April, 2014 and March, 2016 was conducted by a single surgeon in a single hospital (Showa University of Fujigaoka Hospital). We divided the main procedures of the TLH operation into five sections, and measured the time required for each section. These cases were divided into three groups, group 1, 2, and 3. Results: There were 54 cases of TLH over two years for a single surgeon, and 21 cases that included essential operative procedures were divided into three groups of seven cases each. The average duration of the surgery (min.) was 178.3 ± 48.2 in the group 1, 128.3 ± 15.6 in the group 2, and 111.3 ± 15.9 in the group 3. A significant reduction in the required time was observed between group 1, 2, and 3 groups. As the number of cases increased, the operation time became statistically significantly shorter for every section except B and D. The skill growth rate was different at each section. Conclusion: For a single surgeon, as the number of surgical cases increased, we recognized the increased skill with the procedure in every section and the rate of skill growth differed for different sections. The difference of growth rate for each section implied that the number of operative cases required for a surgeon in each section was different.展开更多

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

文摘BACKGROUND Colon cancer is a significant health issue in China,with high incidence and mortality rates.Surgical resection remains the primary treatment,with the introduction of complete mesocolic excision in 2009 improving precision and outcomes.Laparoscopic techniques,including laparoscopic-assisted right hemicolectomy(LARH)and total laparoscopic right hemicolectomy(TLRH),have further advanced colon cancer treatment by reducing trauma,blood loss,and recovery time.While TLRH offers additional benefits such as faster recovery and fewer complications,its adoption has been limited by longer operative times and technical challenges.AIM To compare the short-term outcomes of TLRH and LARH for the treatment of right-sided colon cancer and explore the advantages and feasibility of TLRH.METHODS Clinical data from 109 right-sided colon cancer patients admitted between January 2019 and May 2021 were retrospectively analyzed.Patients were divided into an observation group(TLRH,n=50)and a control group(LARH,n=59).Study variables were operation time,intraoperative bleeding volume,postoperative hospital stays,length of surgical specimen,number of lymph nodes dissected,and postoperative inflammatory factor levels of the two groups of patients.The postoperative complications were analyzed and compared,and survival,recurrence,and remote metastasis rates of the two groups were compared during a 2-year follow-up period.RESULTS The TLRH group showed the advantages of reduced intraoperative bleeding,shorter hospital stays,and quicker recovery.Lymph node dissection outcomes were comparable,and postoperative inflammatory markers were lower in the TLRH group.Complication rates were similar.Short-term follow-up(2 years)revealed no significant differences in recurrence,metastasis,or survival rates.CONCLUSION Compared to LARH,TLRH offers significant advantages in terms of reducing surgical trauma,lowering postoperative inflammatory factor levels,and mitigating the impact on intestinal function.This approach contributes to a shorter hospital stay and promotes postoperative recovery in patients.The study suggests that TLRH may offer favorable outcomes for colorectal cancer patients.
文摘Objective:When performing cervical conization in post-menopausal cervical intraepithelial neoplasia 3(CIN3)patients,the positive rate of endocervical cone margin and the incidence of postoperative cervical stenosis increase.This study summarized a 4-year experience of total laparoscopic hysterectomy as a treatment option for peri-menopausal and post-menopausal CIN3 patients at a single institution.Furthermore,it shared the refinement strategies used during the surgery.Methods:This study retrospectively analyzed the medical records of CIN3 patient aged45 years and who underwent open or laparoscopic hysterectomy at our institution from January 1,2017 to December 31,2020.Totally,30 CIN3 patients were enrolled and divided into abdominal hysterectomy group and laparoscopic hysterectomy based on surgery method,with 5 patients and 25 patients respectively.Results:Compared to the abdominal hysterectomy group,the perioperative blood loss(20 mL vs.220 mL,p=0.004)was less and the duration of in-hospital stay(7 d vs.11 d,p<0.001)were significantly shorter in the laparoscopic hysterectomy group.However,no significant differences in age at hysterectomy(53 y vs.77 y,p=0.054)and operative time(154.4±27.8 min vs.161.0±62.4 min,p=0.826)were observed between them.Diagnostic conization was performed in advance for 12 patients,and among them,10(83.3%)patients had positive endocervical cone margin.Postoperative intestinal obstructionwas noted in one abdominal hysterectomy patient,no other complications were observed in the remaining patients.Conclusion:Compared to conization,hysterectomy is more invasive;however,it is an acceptable treatment option for peri-menopausal and post-menopausal CIN3 patients.In such cases,opting for total laparoscopic hysterectomy adopted the marionette technique might be preferable because the procedure is less invasive.
文摘BACKGROUND: The number of females who undergo liver transplantation is growing and sometimes gynecologic operations are needed to control gynecologic diseases after liver transplantation. METHOD: Total laparoscopic hysterectomy was performed in 2 patients who had undergone liver transplantation, one for adenomyosis and the other for hysteromyoma. RESULTS: It was safe to create a pneumoperitoneum through the umbilical skinfold even though mild adhesion in the pelvic cavity occurred in one patient. The operative times were 95 and 90 minutes, with blood loss of about 100 and 60 ml, respectively. Oral intake, flatus passage, and ambulation recovered within a day, after the operation. No significant changes in liver function were observed except complication of diarrhea caused by Candida albicans in one patient. CONCLUSIONS: The result of the two patients suggest that total laparoscopic hysterectomy is a safe and effective surgical approach for patients who have undergone liver transplantation.

文摘BACKGROUND The liver hemodynamic changes caused by portal hypertension(PH)are closely related to various complications such as gastroesophageal varices and portosystemic shunts,which may lead to adverse clinical outcomes in these patients,so it is of great clinical significance to find treatment strategies with favorable clinical efficacy and low risk of complications.AIM To study the clinical efficacy of total laparoscopic splenectomy(TLS)for PH and its influence on hepatic hemodynamics and liver function.METHODS Among the 199 PH patients selected from October 2016 to October 2020,100 patients[observation group(OG)]were treated with TLS,while the remaining 99[reference group(RG)]were treated with open splenectomy(OS).We observed and compared the clinical efficacy,operation indexes[operative time(OT)and intraoperative bleeding volume],safety(intraperitoneal hemorrhage,ascitic fluid infection,eating disorders,liver insufficiency,and perioperative death),hepatic hemodynamics(diameter,velocity,and flow volume of the portal vein system),and liver function[serum alanine aminotransferase(ALT),serum aspartate aminotransferase(AST),and serum total bilirubin(TBil)]of the two groups.RESULTS The OT was significantly longer and intraoperative bleeding volume was significantly lesser in the OG than in the RG.Additionally,the overall response rate,postoperative complications rate,and liver function indexes(ALT,AST,and TBil)did not differ significantly between the OG and RG.The hepatic hemodynamics statistics showed that the pre-and postoperative blood vessel diameters in the two cohorts did not differ statistically.Although the postoperative blood velocity and flow volume reduced significantly when compared with the preoperative values,there were no significant inter-group differences.CONCLUSION TLS contributes to comparable clinical efficacy,safety,hepatic hemodynamics,and liver function as those of OS in treating PH,with a longer OT but lesser intraoperative blood loss.
文摘BACKGROUND In the presence of a large uterus,total laparoscopic hysterectomy(TLH),always requires morcellation to allow removal of the tissues from the abdominal cavity.However,uncontained morcellation has been scrutinized because of the possible spread of occult leiomyosarcoma.Therefore,in-bag extracorporeal morcellation has been developed.However,tissue containment and extraction are extremely challenging,especially when considering the increasing uterine size to be removed through minimally invasive surgery.CASE SUMMARY Herein,we describe a novel technique for extracorporeal intrauterine morcellation using the uterus outermost layer as a bag to achieve tissue extraction of very large uteri with suspected occult leiomyosarcoma after TLH.The study enrolled patients who were planned for TLH for large uteri(weight>500 g).TLH was performed following the procedure reported in our previous studies.The novel technique has been described step-by-step in a video,which representatively describes the preoperative imaging and morcellation procedure of three very large uteri weighing 1500 g,1700 g,and 3700 g,respectively.The procedures were performed without any complications.The patients had an uneventful postoperative course,and in all cases,the pathology was benign leiomyoma.CONCLUSION Extracorporeal intrauterine morcellation using the uterus outmost layer as a bag was found to be a feasible technique that allows a careful diagnosis and safe removal of suspected occult malignancies.The technique herein presented may be adopted in surgical practice,by adding it to the other available techniques of contained morcellation.It may represent a valid and feasible alternative,especially useful in cases of very large uteri exceeding the capacity of specimen retrieval bags.
文摘Objective:To systematically evaluate and compare the safety and effectiveness of esophagojejunostomy and traditional esophagojejunostomy in total laparoscopic total gastrectomy in the treatment of gastric cancer,providing evidence-based medical evidence for clinical practice.Methods:PubMed,Embase,Cochrane Library,Web of Science,CNKI,Wanfang and VIP databases were searched by computer,and the retrieval time was up to December 2021.Relevant literatures were obtained,and eligible studies were gradually screened and included.Cochrane ROB bias risk assessment tool and NOS scale were used to evaluate the quality of the articles,and required data were extracted from high-quality literatures.Finally,meta-analysis was performed using Review Manager 5.3 software.Results:Eleven studies were finally included,including 1398 patients,including 566 patients receiving overlap anastomosis and 832 patients receiving traditional anastomosis.The results show that overlap anastomosis and traditional anastomosis had the advantages of operation time(MD=0.63,95%CI=7.22,8.48,P=0.88),postoperative first exhaust time(MD=-0.13,95%CI=0.43,0.18,P=0.42),postoperative first feeding time(MD=0.02,95%CI=0.33,0.37,P=0.91),anastomotic leakage(OR=1.38,95%CI=0.73,2.63,P=0.32),and postoperative hospital stay(MD=-0.16,95%CI=0.82,0.51,P=0.64)had no significant differences(all P>0.05).Compared with traditional anastomosis,overlap anastomosis had longer anastomosis time(MD=5.60,95%CI=0.59,10.62,P=0.03),higher incidence of anastomotic bleeding(OR=2.48,95%CI=1.08,5.69,P=0.03),less intraoperative bleeding(MD=-6.42,MD=-6.42,OR=2.48,95%CI=1.08,P=0.03).95%CI=10.28,-2.56,P=0.001)and anastomotic stenosis(OR=0.17,95%CI=0.06,0.46,P=0.0006).Conclusion:Overlap esophagojejunostomy is a safe,effective and prognostic surgical method,and is expected to become the standard esophagojejunostomy in total laparoscopic total gastrectomy.
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 analyze the relationship between the numbers of cases experienced and the operation time for a single surgeon aiming to master the TLH surgical technique. Material and Methods: Retrospective data analysis of women who underwent TLH for benign diseases between April, 2014 and March, 2016 was conducted by a single surgeon in a single hospital (Showa University of Fujigaoka Hospital). We divided the main procedures of the TLH operation into five sections, and measured the time required for each section. These cases were divided into three groups, group 1, 2, and 3. Results: There were 54 cases of TLH over two years for a single surgeon, and 21 cases that included essential operative procedures were divided into three groups of seven cases each. The average duration of the surgery (min.) was 178.3 ± 48.2 in the group 1, 128.3 ± 15.6 in the group 2, and 111.3 ± 15.9 in the group 3. A significant reduction in the required time was observed between group 1, 2, and 3 groups. As the number of cases increased, the operation time became statistically significantly shorter for every section except B and D. The skill growth rate was different at each section. Conclusion: For a single surgeon, as the number of surgical cases increased, we recognized the increased skill with the procedure in every section and the rate of skill growth differed for different sections. The difference of growth rate for each section implied that the number of operative cases required for a surgeon in each section was different.

文摘BACKGROUND With the continuous development of laparoscopic techniques in recent years,laparoscopic total mesorectal excision(LapTME)and laparoscopic-assisted transanal total mesorectal excision(TaTME)have gradually become important surgical techniques for treating low-lying rectal cancer(LRC).However,there is still controversy over the efficacy and safety of these two surgical modalities in LRC treatment.AIM To compare the efficacy of LapTME vs TaTME in patients with LRC.METHODS Ninety-four patients with LRC who visited and were treated at the Affiliated Hengyang Hospital of Hunan Normal University&Hengyang Central Hospital between December 2022 and March 2024 were selected and divided into the LapTME(n=44)and TaTME(n=50)groups.Clinical operation indexes,postoperative recovery indicators,and postoperative complications were recorded.The anal resting pressure(ARP),anal maximum systolic pressure(MSP),and maximum tolerated volume(MTV)of the anal canal were also measured.The intestinal function of patients was evaluated by the Memorial Sloan Kettering Cancer Center(MSKCC)bowel function questionnaire.Serum norepinephrine(NE),adrenaline(AD),and cortisol(Cor)levels were measured.The Quality of Life Questionnaire Core 30(QLQC30)was used for quality of life assessment.RESULTS Compared with the LapTME group,the surgery time in the TaTME group was longer;intraoperative blood loss was low;time of anal exhaust,first postoperative ambulation,intestinal recovery,and hospital stay were shorter;and the distal incisal margin and specimen lengths were longer.The TaTME group also showed higher ARP,MSP,and MTV values and higher MSKCC and QLQ-C30 scores than the LapTME group 3 months postoperatively.Cor,AD,and NE levels were lower in the TaTME group than those in the LapTME group during recovery.CONCLUSION We demonstrated that TaTME better improved anal function,reduced postoperative stress,and accelerated postoperative recovery and,hence,was safer for patients with LRC.
文摘BACKGROUND Early postoperative anastomosis-related complications are frequently associated with technical defects during the anastomotic procedure.Few studies focused on intraoperative anastomotic complications in esophagojejunostomy with circular stapler.AIM To explore whether endoscopic examination could reduce the occurrence of early postoperative anastomotic complications.METHODS Clinical data from 160 patients with gastric cancer who underwent laparoscopic total gastrectomy with esophagojejunostomy using a circular stapler at Nanchong Central Hospital from January 2020 to December 2023 were retrospectively analyzed.Based on whether intraoperative endoscopic examination(IEE)was performed,patients were divided into the IEE group and the non-IEE(NIEE)group.RESULTS All patients successfully underwent laparoscopic total gastrectomy with esophagojejunostomy using a circular stapler.In the IEE group,7(8.8%)patients were found to have anastomotic defects:3(3.8%)air leaks,2(2.5%)bleeding,1(1.3%)stricture and 1(1.3%)full-thickness tearing.Three patients with anastomotic discontinuities were subsequently treated with additional suturing.One anastomotic bleeding was managed with laparoscopic suturing,and another was treated with endoscopic clips.One patient had anastomotic stricture,which was corrected intraoperatively.One patient experienced full-thickness tearing caused by the circular stapler,necessitating a redo anastomosis.These anastomotic defects were repaired intraoperatively,and no postoperative anastomotic complications occurred.6(7.5%)patients with postoperative anastomotic complications were observed in the NIEE group.The NIEE group had a significantly higher incidence of postoperative anastomosis-related complications compared to the IEE group(7.5%vs 0%;P=0.029).CONCLUSION Routine IEE significantly reduces early anastomotic complications by enabling immediate detection and repair of technical defects in esophagojejunostomy with circular stapler.
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 Non-alcoholic fatty liver disease(NAFLD)is characterized by the accumulation of fat in the liver in individuals who do not consume alcohol.Several risk factors influencing the onset of NAFLD after laparoscopic pancreaticoduodenectomy(LPD)have been identified.This study investigated the risk factors associated with the development of fatty liver after laparoscopic duodenum-preserving pancreatic total head resection(LDPPHRt)and LPD.AIM To compare the effects of LDPPHRt and LPD on the development of postoperative NAFLD.METHODS This retrospective cohort study included 59 patients who were histologically diagnosed with benign or low-grade malignant pancreatic tumors and who underwent laparoscopic pancreatic surgery(LDPPHRt or LPD)between May 2020 and April 2023.Patient data on perioperative and postoperative variables were analyzed and compared.Multivariate logistic regression was used to identify pre-,peri-,and postoperative risk factors for NAFLD,with statistical significance set at P<0.05.RESULTS Of the 59 patients included in the study,17(28.8%)developed NAFLD within 6-12 months post-surgery.The incidence of NAFLD was significantly higher in the LPD group compared to the LDPPHRt group(40.0%vs 12.5%,P=0.022).Multivariable analysis identified the LDPPHRt surgical approach(compared to LPD)as an independent protective factor against the development of postoperative NAFLD,with an odds ratio of 0.208(95%confidence interval:0.046-0.931;P=0.040).CONCLUSION Our findings indicate that LDPPHRt is more effective than LPD in reducing the incidence of postoperative NAFLD,which may inform surgical decision-making and optimize patient outcomes after laparoscopic pancreatic surgery.

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BACKGROUND Totally laparoscopic gastrectomy(TLG)entails both gastrectomy and gastrointestinal reconstruction under laparoscopy.Compared with laparoscopic assisted gastrectomy(LAG),TLG has been demonstrated in many studies to require a smaller surgical incision,result in a faster postoperative recovery and less pain and have comparable long-term efficacy,which has been a research hotspot in recent years.Whether TLG is equally safe and feasible for elderly patients remains unclear.AIM To compare the short-term efficacy of and quality of life(QOL)associated with TLG and LAG in elderly gastric cancer(GC)patients.METHODS The clinicopathological data of 462 elderly patients aged≥70 years who underwent LAG or TLG(including distal gastrectomy and total gastrectomy)between January 2017 and January 2022 at the Department of General Surgery,First Medical Center,Chinese PLA General Hospital were retrospectively collected.A total of 232 patients were in the LAG group,and 230 patients were in the TLG group.Basic patient information,clinicopathological characteristics,operation information and QOL data were collected to compare efficacy.Compared with those in the LAG group,intraoperative blood loss in the TLG group was significantly lower(P<0.001),and the time to first flatus and postoperative hospitalization time were significantly shorter(both P<0.001).The overall incidence of postoperative complications in the TLG group was significantly lower than that in the LAG group(P=0.01).Binary logistic regression results indicated that LAG and an operation time>220 min were independent risk factors for postoperative complications in elderly patients with GC(P<0.05).In terms of QOL,no statistically significant differences in various preoperative indicators were found between the LAG group and the LTG group(P>0.05).Compared with the laparoscopic-assisted total gastrectomy group,patients who received totally laparoscopic total gastrectomy had lower nausea and vomiting scores and higher satisfaction with their body image(P<0.05).Patients who underwent laparoscopic-assisted distal gastrectomy were more satisfied with their body image than patients in the totally laparoscopic distal gastrectomy group(P<0.05).CONCLUSION TLG is safe and feasible for elderly patients with GC and has outstanding advantages such as reducing intracorporeal blood loss,promoting postoperative recovery and improving QOL.

文摘BACKGROUND Prophylactic drains have been used to remove intraperitoneal collections and detect complications early in open surgery.In the last decades,minimally invasive gastric cancer surgery has been performed worldwide.However,reports on routine prophylactic abdominal drainage after totally laparoscopic distal gastrectomy are few.AIM To evaluate the feasibility performing totally laparoscopic distal gastrectomy without prophylactic drains in selected patients.METHODS Data of patients with distal gastric cancer who underwent totally laparoscopic distal gastrectomy with and without prophylactic drainage at China National Cancer Center/Cancer Hospital from February 2018 to August 2019 were reviewed.The outcomes between patients with and without prophylactic drainage were compared.RESULTS A total of 457 patients who underwent surgery for gastric cancer were identified.Of these,125 patients who underwent totally laparoscopic distal gastrectomy were included.After propensity score matching,data of 42 pairs were extracted.The incidence of concurrent illness was higher in the drain group(42.9%vs 31.0%,P=0.258).The overall postoperative complication rates were 19.5%and 10.6%in the drain(n=76)and no-drain groups(n=49),respectively;there were no significant differences between the two groups(P>0.05).The difference between the two groups based on the need for percutaneous catheter drainage was also not significant(9.8%vs 6.4%,P=0.700).However,patients with a larger body mass index(≥29 kg/m2)were prone to postoperative complications(P=0.042).In addition,the number of days from surgery until the first flatus(4.33±1.24 d vs 3.57±1.85 d,P=0.029)was greater in the drain group.CONCLUSION Omitting prophylactic drainage may reduce surgery time and result in faster recovery.Routine prophylactic drains are not necessary in selected patients.A prophylactic drain may be useful in high-risk patients.
文摘BACKGROUND Intraoperative methylene blue testing(IMBT),air leak testing,or endoscopy is used to assess the anastomotic integrity of esophagojejunostomy during open total gastrectomy for gastric cancer.Totally laparoscopic radical gastrectomy has been widely used to treat gastric cancer in the last few decades.However,reports on testing anastomotic integrity in totally laparoscopic radical gastrectomy are limited.AIM To explore the effects of IMBT on the incidence of postoperative anastomotic leaks(PALs)and identify the risk factors for PALs in totally laparoscopic radical gastrectomy.METHODS From January 2017 to December 2019,patients who underwent totally laparoscopic radical gastrectomy at the Shaanxi Provincial People's Hospital were retrospectively analyzed.According to whether or not they experienced an IMBT,the patients were divided into an IMBT group and a control group.If the IMBT was positive,an intraoperative suture was required to reinforce the anastomosis.The difference in the incidence of PALs was compared,and the risk factors were investigated.RESULTS This study consisted of 513 patients,211 in the IMBT group and 302 in the control group.Positive IMBT was shown in seven patients(3.3%)in the IMBT group,and no PAL occurred in these patients after suture reinforcement.Multivariate analysis showed that risk factors for predicting positive IMBT were body mass index(BMI)>25 kg/m2(hazard ratio[HR]=8.357,P=0.009),operation time>4 h(HR=55.881,P=0.002),and insufficient surgical experience(HR=15.286,P=0.010).Moreover,15 patients(2.9%)developed PALs in 513 patients,and the rates of PALs were significantly lower in the IMBT group than in the control group[2 of 211 patients(0.9%)vs 13 of 302 patients(4.3%),P=0.0026].Further analysis demonstrated that preoperative complications(HR=13.128,P=0.017),totally laparoscopic total gastrectomy(HR=9.075,P=0.043),and neoadjuvant chemotherapy(HR=7.150,P=0.008)were independent risk factors for PALs.CONCLUSION IMBT is an effective method to evaluate the integrity of anastomosis during totally laparoscopic radical gastrectomy,thus preventing technical defect-related anastomotic leaks.Preoperative complications,totally laparoscopic total gastrectomy,and neoadjuvant chemotherapy are independent risk factors for PALs.
