Now, however, endoscopic suturing has evolved sufficiently to be easily implemented during procedures and is more commonly used by gastroenterologists. We have employed the Apollo Over Stitch suturing device in a variety of ways including closure of perforations, closure of full thickness defects in the gastrointestinal wall created during endoscopic full thickness resection, closure of mucosotomies during peroral endoscopic myotomy, stent fixation, fistula closure, post endoscopic submucosal dissection, endoscopic mucosal resection and Natural Orifice Transluminal Endoscopic Surgery defect closures, post-bariatric surgery gastrojejunal anastomosis revision and primary sleeve gastroplasty.展开更多

The Ili and Toksun-Yamansu terranes had been split from the Tarim plate before the Middle Devonian and then went close to Angaraland in the late Early Permian. The Beishan area on the northeastern margin of the Tarim plate came close to Angaraland first in the early Early Permian. The suturing age between the Tarim and Kazakhstanian-Siberian plates is generally the same as that between the Turkey-Central Iran-Gangdise and South China-Southeast Asian plates. The suturing event took place in the early Early Permian, while the corresponding tectogeny occurred between the Early and Late Permian.展开更多

One is charac-terized by the Permo-Carboniferous ice-rafted marine gravel-bearing clastic formation and the cold-water faunaof the Gondwana facies, including the Gangmar Co, Lhasa, Sa' gya, Tengchong and Baoshan terranes and theother is marked by the Upper Palaeozoic of the Yangtze type with the Cathaysian flora and the Pacific-typefusulinids, comprising the Changning-Menglian, Shuangjiang-Lancang, Qamdo and Bayan Har terranes. TheLongmu Co-Shuanghu-Dengqen-North Lancang River-Kejie-Mengding suture zone between the two groups ofterranes is the boundary between Gondwana and Pacifica in southwestern China. On the grounds of thesedimentary formation and successive southwestward migration of the Asian nonmarine Jurassic-Cretaceousendemic bivalves, the ages of the suture and some terranes to the southwest of the suture zone are discussed.The Baoshan terrane and the Nyainrong-Sog terrane in the Lhasa composite terrane were firstly pieced togeth-er with the Asian continent in the early Early Jurassic. The northern Tibet-western Yunnan microplate, in-cluding the Gangmar Co, Lhasa and Tengchong terranes, collided with the Asian continent at the end of theEarly Cretaceous Neocomian.展开更多

Materials and Methods: Case series included 12 eyes of 12 patients who underwent Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) in the presence of high risk for graft dislocation factors. We describe a surgical technique that uses a transcorneal fixation suture to compress the donor graft onto the back surface of the recipient cornea. Outcome measures included intraoperative and postoperative complications, graft attachment and clarity and endothelial cell count at a 12 months follow-up period. Results: No intraoperative complications were noted and 11 grafts remained attached and clear with no suture related complications at a 12-month follow-up period. Partial peripheral graft detachment due to suture related graft folds, accompanied by mild corneal edema was noticed in one patient postoperatively. Reattachment and edema resolution occurred spontaneously after suture removal. The mean endothelial cell loss was 38.21% at 12 months. Conclusions: Temporary transcorneal fixation suture can be helpful in preventing graft detachment in eyes with high risk for graft dislocation.展开更多

Given the different reports found in the literature concerning peritoneal closure mostly in obstetrics and gynecology, any objective information based on statistically tested results may be of great value in the everyday surgery practice. Material and Method: This is an experimental model on which a laparotomy is performed on the free cavity of the abdominal wall in growing rats. Young Wistar rats (approximately 1 month old) were operated through a long median xipho-umbilical abdominal incision. The animals were divided in 3 groups with fifteen rats each: in Group I, only the peritoneum was left open and all the other layers of the abdominal wall were closed;the rats in Group II had their peritoneums closed with unabsorbable cord (Prolene 4-0, Ethicon?). The abdominal wall of the rats in Group III (control) was only opened up to the musculature. The peritoneum, which remained intact and closed, was carefully prodded with the grip of tweezers to avoid lesions and/or perforations in the peritoneum. Results: There were no deaths nor incisional dehiscence and/or hernias among the animals. Nine animals of Group I presented adhesions (60%), whereas there were adhesions in all the fifteen animals of Group II (100%). In Group III adhesions were found in two animals (13%). The percentage of adhesions in Group II was significantly higher than those observed in Groups I and III (p 0.0001). Adhesions were mostly formed by the abdominal omentum. It was not observed any effect of the procedure on viscera. Conclusion: The experimental model that was suggested is appropriate for the establishment and study of peritoneal adhesions. The rate of adhesions found in the Group II was significantly higher (p 0.0001) than the rate observed in the Group I and Group III, suggesting that peritoneum suture can play a important role in the adhesion processes.展开更多

文摘BACKGROUND At present,prophylactic ileostomy is commonly used to protect distal intestinal anastomoses,particularly during the recovery period following colorectal surgery.However,after the ileum is returned to the abdominal cavity,abdominal closure using traditional vertical interrupted suturing is associated with a higher incidence of wound infections.For patients undergoing ileostomy closure,selecting an appropriate suturing method for the skin incision at the stoma site is crucial for improving patient prognosis.AIM To investigate the impact of three different skin suturing methods at the ileostomy closure site on patient prognosis.METHODS Thirty patients who underwent ileostomy closure at the Affiliated Hospital of Qinghai University between January 2024 and October 2024 were selected based on inclusion and exclusion criteria.The patients were divided into three groups:The purse-string suture group,the cross-suture group,and the vertical interrupted suture group,with 10 cases in each group.The purse-string suture group,cross-suture group,and vertical interrupted suture group used purse-string,cross,and vertical interrupted suturing methods,respectively,for the skin incision at the ileostomy closure site.RESULTS There were no statistically significant differences among the three groups in terms of operative time,intraoperative blood loss,time to resume liquid diet,time to first bowel movement,postoperative hospital stay,hospitalization costs,or levels of white blood cell count,hemoglobin,and albumin on the third postoperative day(P>0.05).Nevertheless,significant differences(P<0.05)were observed in incision suture removal time,wound healing time,C-reactive protein levels on the third postoperative day,visual analog scale pain scores during the first three postoperative days,and the incidence of surgical site infection.Overall,the therapeutic outcomes of the pursestring suture group and the cross-suture group were superior to the vertical interrupted suture group.CONCLUSION Using purse-string or cross-suturing methods for skin incision at the ileostomy closure site can shorten wound healing and suture removal times,reduce surgical site infection incidence and postoperative inflammatory response,alleviate incision pain,and promote rapid postoperative recovery.

文摘Minimally invasive surgery(MIS)robots,such as single-arm stapling robots,are key to oral and maxillofacial surgery because they overcome space constraints in the oral cavity and deep throat.However,biodegradable suture staples should be developed for the single-arm stapling robots to avoid a secondary operation.For this aim,a new type of Mg-3Zn-0.2Ca-2Ag biodegradable alloy wire was developed in this study applied as suture staples.Its tensile strength,yield strength,and elongation are 326.1 MPa,314.5 MPa,and 19.6%,respectively.Especially,the alloy wire attains the highest yield strength value reported among all the biodegradable Mg wires,which is mainly attributed to fine grain strengthening and second phase strengthening such as Mg_(2)Zn_(11) nano phase strengthening.Moreover,the corrosion rate of this alloy wire in simulated body fluid(SBF)reaches 26.8 mm/y,the highest value among all the biodegradable Mg alloy wires reported so far,which is mainly from the intensified galvanic corrosion between the Ag17Mg54 phase and the Mg matrix.In vitro studies demonstrate that the alloy wire exhibits good blood compatibility and low cytotoxicity.The cone beam computed tomography(CBCT)data shows that the suture staple made of the Mg alloy wire provides better mechanical support in the early postoperative period.From the single arm robot tests,it confirms that suture staples can close the wound tightly and remain stable over time.This research provides a good material selection for the automated suturing in oral and throat surgery robots.
文摘Endoscopic suturing had previously been considered an experimental procedure only performed in a few centers and often by surgeons. Now, however, endoscopic suturing has evolved sufficiently to be easily implemented during procedures and is more commonly used by gastroenterologists. We have employed the Apollo Over Stitch suturing device in a variety of ways including closure of perforations, closure of full thickness defects in the gastrointestinal wall created during endoscopic full thickness resection, closure of mucosotomies during peroral endoscopic myotomy, stent fixation, fistula closure, post endoscopic submucosal dissection, endoscopic mucosal resection and Natural Orifice Transluminal Endoscopic Surgery defect closures, post-bariatric surgery gastrojejunal anastomosis revision and primary sleeve gastroplasty.
文摘Exposed endoscopic full-thickness resection(EFTR)without laparoscopic assistance is a minimally invasive natural orifice transluminal endoscopic surgery technique that is emerging as a promising effective and safe alternative to surgery for the treatment of muscularis propria-originating gastric submucosal tumors.To date,various techniques have been used for the closure of the transmural postEFTR defect,mainly consisting in clip-and endoloop-assisted closure methods.However,the recent advent of dedicated tools capable of providing full-thickness defect suture could further improve the efficacy and safety of the exposed EFTR procedure.The aim of our review was to evaluate the efficacy and safety of the different closure methods adopted in gastric-exposed EFTR without laparoscopic assistance,also considering the recent advent of flexible endoscopic suturing.
文摘AIM:To prevent pancreatic leakage after pancreaticoje-junostomy,we designed a new standardized technique that we term the "Pair-Watch suturing technique".METHODS:Before anastomosis,we imagine the faces of a pair of watches on the jejunal hole and pancreatic duct.The first stitch was put between 9 o'clock of the pancreatic side and 3 o'clock of the jejunal side,and a total of 7 stitches were put on the posterior wall,followed by the 5 stitches on the anterior wall.Using this technique,twelve stitches can be sutured on the first layer anastomosis regardless of the caliber of the pancreatic duct.In all cases the amylase activity of the drain were measured.A postoperative pancreatic fistula was diagnosed using postoperative pancreatic fistula grading.RESULTS:From March 2007 to July 2008,29 consecutive cases underwent pancreaticojejunostomy using this technique.Pathologic examination results showed pancreatic carcinoma(n=14),intraductal papillary-mucinous neoplasm(n=10),intraductal papillary-mucinous carcinoma(n=1),carcinoma of ampulla of Vater(n=1),carcinoma of extrahepatic bile duct(n=1),metastasis of renal cell carcinoma(n=1),and duodenal carcinoma(n=1).Pancreaticojejunal anastomoses using this technique were all watertight during the surgical procedure.The mean diameter of main pancreatic duct was 3.4 mm(range 2-7 mm).Three patients were recognized as having an amylase level greater than 3 times the serum amylase level,but all of them were diagnosed as grade A postoperative pancreatic fistula grading and required no treatment.None of the cases developed complications such as hemorrhage,abdominal abscess,and pulmonary infection.There was no postoperative mortality.CONCLUSION:Our technique is less complicated than other methods and very secure,providing reliable anastomosis for any size of pancreatic duct.
文摘Abstract: The Kazakhstanian plate was near the Tarim, Sino-Korean and South China-Southeast Asian plates in the Middle-Late Cambrian and Late Ordovician, and approached the Siberian plate in the other periods of the Early Palaeozoic. The Ili and Toksun-Yamansu terranes had been split from the Tarim plate before the Middle Devonian and then went close to Angaraland in the late Early Permian. The Beishan area on the northeastern margin of the Tarim plate came close to Angaraland first in the early Early Permian. The suturing age between the Tarim and Kazakhstanian-Siberian plates is generally the same as that between the Turkey-Central Iran-Gangdise and South China-Southeast Asian plates. The suturing event took place in the early Early Permian, while the corresponding tectogeny occurred between the Early and Late Permian.
文摘BACKGROUND Although endoscopic submucosal dissection(ESD)is becoming more common for early gastric cancer,it requires more advanced techniques and a longer treatment duration than endoscopic mucosal resection.Hybrid ESD using a multifunctional snare(SOUTEN)has been reported to be effective for colorectal lesions,as it can reduce treatment duration.Endoscopic suturing of post-ESD mucosal defects has been reported to reduce the incidence of ESD-related complications.CASE SUMMARY This study reports outpatient hybrid ESD for early gastric cancer using SOUTEN,followed by endoscopic suturing of post-ESD mucosal defects in an 86-year-old man.On referral for ESD,a 10-mm flat,depressed lesion was found on the posterior wall of the gastric antrum,the depth of which was expected to be mucosal.Given his history of delirium,we performed outpatient endoscopic treatment.The procedure used was hybrid ESD using SOUTEN to reduce the duration of treatment and endoscopic suturing of post-ESD mucosal ESD defects to reduce complications.The procedure time was 62 min and the lesion was completely resected based on histopathological examination,with no reported postoperative complications.CONCLUSION This safe and useful procedure may be especially important for outpatient endoscopic treatment.
文摘This study explores the clinical application of the circular wide and deep(looped,broad,and deep buried,LBD)suture technique for scar resection and examines its clinical effectiveness for scar treatment.From June 2017 to March 2019,a total of 68 patients with scars were sutured using LBD technique,and recovery was achieved 24 months postoperatively.In all 68 patients,postoperative scars were slightly evident in two cases of cervical scar,one case of leg scar,and one case of chest scar.In addition,the remaining 62 patients were completely satisfied with the outcome.The LBD suturing technique could provide sustained and stable tension-reducing effects postoperatively and significantly improve scar formation in patients.This method is most applicable to incisions with tension.Therefore,it should be more widely used for clinical scar treatment.
文摘Keloids are fibroproliferative disorders that can result from cutaneous injuries to the reticular dermis.Recurrence rates as high as 100%have been reported following surgical excision alone.Consequently,a variety of post-surgical techniques have been employed to prevent keloid recurrence,including the use of radiation.Although numerous studies have shown that post-excisional X-rays,electron beams,lasers,and brachytherapy can reduce the rate of keloid recurrence,numerous inconsistencies,including a wide range of definitions for keloid recurrence,render it difficult to compare the outcomes.The treatment of severe keloids in children is much more challenging,and there have been few previous reports.It is generally believed that children with keloids should be treated with nonsurgical treatment such as hormone injections and radiotherapy.For severe keloids,these methods require a long treatment period,and their efficacy is not ideal.Moreover,the side effects of the treatment can affect children’s health.If keloid scars are not effectively treated,they will often seriously affect the physical and mental health of children.The purpose of this review is to discuss case studies of children with severe keloids who were only treated with surgery and their postoperative recovery.In this case,the deep-embedded circular mattress suture technique(LBD,the looped,broad,and deep buried suturing technique)was used in the scar resection.After 18 months of follow-up,the surgical scar was evaluated using the Vancouver Scar Scale(VSS).The scar was stable and did not recur.The child was satisfied.This case shows that it is completely feasible to treat severe keloids with surgery alone,as long as the tension is reduced during the operation to prevent surgical scar hyperplasia.
文摘Two terranes formed since the Late Palaeozoic can be distinguished in southwestern China. One is charac-terized by the Permo-Carboniferous ice-rafted marine gravel-bearing clastic formation and the cold-water faunaof the Gondwana facies, including the Gangmar Co, Lhasa, Sa' gya, Tengchong and Baoshan terranes and theother is marked by the Upper Palaeozoic of the Yangtze type with the Cathaysian flora and the Pacific-typefusulinids, comprising the Changning-Menglian, Shuangjiang-Lancang, Qamdo and Bayan Har terranes. TheLongmu Co-Shuanghu-Dengqen-North Lancang River-Kejie-Mengding suture zone between the two groups ofterranes is the boundary between Gondwana and Pacifica in southwestern China. On the grounds of thesedimentary formation and successive southwestward migration of the Asian nonmarine Jurassic-Cretaceousendemic bivalves, the ages of the suture and some terranes to the southwest of the suture zone are discussed.The Baoshan terrane and the Nyainrong-Sog terrane in the Lhasa composite terrane were firstly pieced togeth-er with the Asian continent in the early Early Jurassic. The northern Tibet-western Yunnan microplate, in-cluding the Gangmar Co, Lhasa and Tengchong terranes, collided with the Asian continent at the end of theEarly Cretaceous Neocomian.
文摘Aim: To develop a method for closure of the arthrotomy wound and approximation of the medial periosteum at the level of tibial tuberosity after total knee arthroplasty in severe varus deformity. Method: We describe a technique of osteotendinous suturing through the tibial tuberosity for suturing of the medially elevated periosteum. Result: This is an easily reproducible technique which results in very early mobilisation and no additional complications and has several advantages over other methods of closure. Conclusion: The osteotendinous technique can be used for medial arthrotomy closure after correction of severe varus deformities and also after partial patellar tendon avulsions in total knee arthroplasty surgeries.
文摘AIM：To present a novel scleral flap suturing technique for filtering glaucoma surgery in order to control high postoperative intraocular pressure（IOP）.METHODS：Description of ‘the accordion suture＇ technique for mitomycin C augmented trabeculectomy.In cases of postoperative high IOP,pulling the loop of the suture helps to lift up the scleral flap by an even pressure on both edges.By means of this technique,the scleral flap opens up in an ‘‘accordion＇＇ manner,thus preventing flap obstruction and providing adequate aqueous flow.RESULTS：Our study group consisted of 8 eyes of 8 patients with neovascular glaucoma.Mean age of the subjects was 67.42±8.21 y and female/male ratio was 4/4.Mean preoperative IOP was 37±7.48 mm Hg.Mitomycin C augmented trabeculectomy was carried out on the subjects without any complications.The scleral flap closure is performed with three separate sutures;initially,our accordion suture through the center of the flap,and two releasable sutures on both corners.All the patients received removal of two side releasable sutures concomitant with pulling the accordion suture,without any complications.The average traction time was 3.5±0 wk postoperatively.The mean postoperative IOP was 11.37±2.72 mm Hg.No suture related complications were observed.CONCLUSION：This technique can be the suture of choice for filtering glaucoma surgery in experienced hands by its easy learning curve for precisely indicated patients.
文摘BACKGROUND Sutures have been used to repair wounds since ancient times.However,the basic suture technique has not significantly changed.In Phase I of our project,we proposed a“double diabolo”suture design,using a theoretical physical study to show that this suture receives 50%less tension than conventional sutures,and so a correspondingly greater force must be applied to break it.AIM To determine whether these theoretical levels of resistance were met by the new type of suture.METHODS An observational study was performed to compare three types of sutures,using a device that exerted force on the suture until the breaking point was reached.The tension produced by this traction was measured.The following variables were considered:Tearing stress on entry/exit points,edge separation stress,and suture break stress.The study sample consisted of 30 sutures with simple interrupted stitches(Group 1),30 with continuous stitches(Group 2),and 30 with the“double diabolo”design(Group 3).RESULTS The mean degree of force required to reach the breaking point for each of these variables(tearing,separation,and final breaking)was highest in Group 3(14.56,18.28,and 21.39 kg),followed by Group 1(7.36,10.38,and 12.81 kg)and Group 2(5.77,7.7,and 8.71 kg).These differences were statistically significant(P<0.001)in all cases.CONCLUSION The experimental results show that with the“double diabolo”suture,compared with conventional sutures,greater force must be applied to reach the breaking point(almost twice as much as in the simple interrupted suture and more than double that required for the continuous suture).If these results are confirmed in Phase III(the clinical phase)of our study,we believe the double diabolo technique should be adopted as the standard approach,especially when the suture must withstand significant tension(e.g.,laparotomy closure,thoracotomy closure,diaphragm suture,or hernial orifice closure).
文摘Aims: To describe a technique that uses a transcorneal fixation suture for graft attachment in endothelial keratoplasty in high-risk for graft dislocation eyes. Materials and Methods: Case series included 12 eyes of 12 patients who underwent Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) in the presence of high risk for graft dislocation factors. We describe a surgical technique that uses a transcorneal fixation suture to compress the donor graft onto the back surface of the recipient cornea. Outcome measures included intraoperative and postoperative complications, graft attachment and clarity and endothelial cell count at a 12 months follow-up period. Results: No intraoperative complications were noted and 11 grafts remained attached and clear with no suture related complications at a 12-month follow-up period. Partial peripheral graft detachment due to suture related graft folds, accompanied by mild corneal edema was noticed in one patient postoperatively. Reattachment and edema resolution occurred spontaneously after suture removal. The mean endothelial cell loss was 38.21% at 12 months. Conclusions: Temporary transcorneal fixation suture can be helpful in preventing graft detachment in eyes with high risk for graft dislocation.

文摘Purpose: The purpose of the present study was to determine the effect of peritoneal closure on the formation of abdominal adhesions by verifying their degree of damage on intestinal portions and the omentum with the abdominal wall. Given the different reports found in the literature concerning peritoneal closure mostly in obstetrics and gynecology, any objective information based on statistically tested results may be of great value in the everyday surgery practice. Material and Method: This is an experimental model on which a laparotomy is performed on the free cavity of the abdominal wall in growing rats. Young Wistar rats (approximately 1 month old) were operated through a long median xipho-umbilical abdominal incision. The animals were divided in 3 groups with fifteen rats each: in Group I, only the peritoneum was left open and all the other layers of the abdominal wall were closed;the rats in Group II had their peritoneums closed with unabsorbable cord (Prolene 4-0, Ethicon?). The abdominal wall of the rats in Group III (control) was only opened up to the musculature. The peritoneum, which remained intact and closed, was carefully prodded with the grip of tweezers to avoid lesions and/or perforations in the peritoneum. Results: There were no deaths nor incisional dehiscence and/or hernias among the animals. Nine animals of Group I presented adhesions (60%), whereas there were adhesions in all the fifteen animals of Group II (100%). In Group III adhesions were found in two animals (13%). The percentage of adhesions in Group II was significantly higher than those observed in Groups I and III (p 0.0001). Adhesions were mostly formed by the abdominal omentum. It was not observed any effect of the procedure on viscera. Conclusion: The experimental model that was suggested is appropriate for the establishment and study of peritoneal adhesions. The rate of adhesions found in the Group II was significantly higher (p 0.0001) than the rate observed in the Group I and Group III, suggesting that peritoneum suture can play a important role in the adhesion processes.

文摘BACKGROUND In recent years,endoscopic resection(ER)has been employed for the excision of submucosal tumors(SMTs).Nonetheless,ER in the duodenum is linked to ele-vated risks of both immediate and delayed hemorrhagic complications and perforations.Satisfactory suturing is crucial for reducing the occurrence of complications.AIM To establish a clinical score model for supporting suture decision-making of duodenal SMTs.METHODS This study included 137 individuals diagnosed with duodenal SMTs who under-went ER.Participants were evenly divided into two groups:A training cohort(TC)comprising 95 cases and an internal validation cohort(VC)with 42 cases.Subsequently,a scoring system was formulated utilizing multivariate logistic regression analysis within the TC,which was then subjected to evaluation in the VC.RESULTS The clinical scoring system incorporated two key factors:Extraluminal growth,which was assigned 2 points,and endoscopic full-thickness resection,which was given 3 points.This model demonstrated strong predictive accuracy,as evidenced by the area under the receiver operating characteristic curve of 0.900(95%confidence interval:0.823-0.976).Additionally,the model’s goodness-of-fit was validated by the Hosmer-Lemeshow test(P=0.404).The probability of purse-string suturing in low(score 0-2)and high(score>3)categories were 3.0%and 64.3%in the TC,and 6.1%and 88.9%in the VC,respectively.CONCLUSION This scoring system may function as a beneficial instrumentality for medical practitioners,facilitating the decision-making process concerning suture techniques in the context of duodenal SMTs.
文摘BACKGROUND Anastomotic leakage(AL)is a challenging complication following rectal cancer surgery,often leading to increased morbidity and healthcare costs.The use of reinforcement sutures is expected to reduce the rate of AL,their preventive effects are controversial.AIM To determine the efficacy of reinforcing sutures in preventing AL in rectal cancer.METHODS A systematic search of major medical databases was conducted to identify studies up to June 2024.Intraoperative and postoperative outcomes were assessed;the primary outcome assessed was the incidence of AL.Pooled odds ratios(ORs)and mean differences(MDs)with a 95%confidence interval(CI)were calculated using fixed-effect or random-effect models under heterogeneity.RESULTS This meta-analysis incorporated 20 studies involving 3726 patients.Pooled results demonstrated a statistically significant reduction AL incidence in the reinforced suture group(OR:0.26,95%CI:0.19-0.35,P<0.001)than the unreinforced suture group.The reinforced suture group also exhibited a shorter hospital stay(MD:-1.17,95%CI:-1.78 to-0.57,P<0.001),earlier anal exhaust(MD:-0.13,95%CI:-0.22 to-0.05,P=0.002),longer operative time(MD:15.25,95%CI:10.71-19.80,P<0.001),lower infection rate(OR:0.54,95%CI:0.29-1.00,P=0.05)and lower reoperation rate(OR:0.19,95%CI:0.08-0.45,P<0.001).CONCLUSION The results substantiate the clinical value of anastomotic reinforcement sutures in reducing AL incidence postrectal cancer surgery.Nevertheless,these conclusions warrant verification through additional high-quality randomized controlled trials.
文摘BACKGROUND Sleeve fracture of the patella is an unusual fracture,almost unique to children.The majority of sleeve fractures involve the inferior patellar pole.However,sleeve fractures of the superior pole of the patella are extremely rare in adults.CASE SUMMARY An 18-year-old male patient fell while running in the morning.The patient had tenderness to palpation at the superior pole of the patella,with a palpable gap over the upper part of the patella in both knees.We applied two 4.5-mm suture anchors with the Krackow stitch to repair the sleeve fracture,augmented by autogenous gracilis through performing the figure-of-eight technique.The patient regained approximately the full range of motion of the knee joint without any quadriceps weakness and a normal gait 6 weeks after surgery.CONCLUSION Sleeve fractures of the superior pole of the patella are extremely rare in adults,especially bilateral sleeve fractures.Suture anchors,augmented by autogenous gracilis,provided secure fixation and achieved excellent results in this rare injury.
文摘BACKGROUND Both the etiology and treatment of perianal fistulas present challenges,and there is no standard surgical approach.AIM To present the results of a modified fistulotomy technique that was implemented in a tertiary coloproctology reference center.METHODS Seventy-two patients who underwent surgical intervention for perianal fistula between August 2019 and January 2023 were treated using a modified fistulotomy technique.In this approach,the fistula tract was excised from the external opening up to the external sphincter fibers.The internal orifice was widened,and the septic focus within the inter sphincteric space was curetted.Partial internal sphincterotomy was performed up to the inter sphincteric plane.The anoderm from the internal orifice to the inter sphincteric space was closed with absorbable suture material,and a loose seton was placed at the level of the external sphincter.RESULTS The 72 patients who underwent modified fistulotomy were 77.8%male and 22.2%female,with a mean age of 42.2±11.5 years.The median follow-up period was 19 months.Preoperatively,93.1%of patients had high trans sphincteric fistulas,and 6.9%were females with anterior low trans sphincteric fistulas.In all cases,setons were placed during surgery using vascular tape.A total of 12.5%of patients experienced incontinence,involving gas(6.9%)or soiling(5.6%).There were no reports of solid or liquid incontinences.Complete healing was achieved in 83.3%of the patients,with a recurrence rate of 4.2%and a non-healing rate of 12.5%.CONCLUSION Our preliminary analysis suggests that this modified fistulotomy technique that targets distalization of the internal orifice is a promising alternative management strategy for perianal fistulas.
文摘BACKGROUND The purpose of this systematic review was to evaluate the clinical and radiological outcomes at short-term follow-up following suture button fixation for the management of ligamentous Lisfranc injuries.AIM To assess the effectiveness of suture button fixation in managing ligamentous Lisfranc injuries through a systematic evaluation of short-term clinical and radiological outcomes.METHODS During March 2024,the PubMed,EMBASE,and Cochrane library databases were systematically reviewed to identify clinical studies examining outcomes following suture button fixation for the management of ligamentous Lisfranc injuries.Data regarding patient demographics,pathological characteristics,subjective clinical outcomes,radiological outcomes,complications,and failure rates were extracted and analyzed.RESULTS Eight studies were included.In total,94 patients(94 feet)underwent suture button fixation for the management of ligamentous Lisfranc injuries at a weighted mean follow-up of 27.2±10.2 months.The American Orthopaedic Foot and Ankle Society score improved from a weighted mean pre-operative score of 39.2±11.8 preoperatively to a post-operative score of 82.8±5.4.The weighted mean visual analogue scale score improved from a weighted mean pre-operative score of 7.7±0.6 preoperatively to a post-operative score of 2.0±0.4.In total,100%of patients returned to sport at a mean time of 16.8 weeks.The complication rate was 5%,the most common complication of which was residual midfoot stiffness(3.0%).No failures nor secondary surgical procedures were recorded.CONCLUSION This systematic review demonstrated that suture button fixation for ligamentous Lisfranc injuries produced improved clinical outcomes at short-term follow-up.In addition,there was an excellent return-to-sport rate(100%)at a weighted mean time of 16.8 weeks.This review highlights that suture button fixation is a potent surgical treatment strategy for ligamentous Lisfranc injuries;however,caution should be taken when evaluating this data in light of the lack of high quality,comparative studies,and short-term follow-up.
