BACKGROUND Anastomotic leakage(AL) is a severe complication in rectal cancer surgery.Various methods, including intracorporeal reinforcing suturing, have been used to reduce the incidence of AL. However, little is known about the efficacy of staple-line reinforcement by barbed suture for preventing AL.AIM To evaluate the efficacy of staple-line reinforcement using barbed suture for preventing AL in laparoscopic surgery for rectal cancer.METHODS We retrospectively reviewed the clinical datum of 319 patients undergoing laparoscopic low anterior resection combined with double stapling technique between May 1, 2017 and January 31, 2021. All surgeries were performed by the same surgical team specializing in colorectal surgery. Patients were divided into two groups depending on whether they received reinforcing sutures. Patients’ baseline characteristics did not show any significant difference between the two groups. We analyzed patient-, tumor-, as well as surgery-related variables using univariate and multivariate logistic analyses.RESULTS There were 168 patients in the reinforcing suture group and 151 patients in the non-reinforcing suture group. AL occurred in 25 cases(7.8%). Its incidence was significantly higher in the non-reinforcing suture group than in the reinforcing suture group(4.8% vs 11.3%, P = 0.031). The multivariate analyses demonstrated that the tumor site, tumor size and presence of staple-line reinforcement were independent risk factors for AL. We divided these patients into two risk groups based on the combination of tumor site and tumor size. Patients without any risk factor were assigned to the low-risk group(n = 177), whereas those having one or two risk factors were assigned to the high-risk group(n = 142). In the high-risk group, the AL incidence considerably decreased in the reinforcing suture group compared with that in the non-reinforcing suture group(P = 0.038). Nonetheless, no significant difference was found in the low-risk group between the two groups.CONCLUSION Staple-line reinforcement by barbed suture may decrease the incidence of AL. A large-scale prospective randomized controlled trial is needed for evaluating the efficacy of staple-line reinforcement for preventing AL. 展开更多

Embedding thread lift rhytidectomy,also known as“thread lifting”in China,with the natures of simple operation,less trauma and quick recovery,is progressively used in clinical practice as a new technology of face lifting.Herewith,a brief introduction of the previous advances of thread lifting techniques and materials in the facial beauty industry,combined with the discussion on various types of sutures,common complications,and the site of actions were provided.The main limitations of present thread lifting material include:(1)the use of non-absorbable sutures is liable to cause allergies and a series of complications;(2)the absorbable sutures are easily degradation,and people need to reshape in a relatively short period.Therefore,the high biocompatible spider silk was proposed as a novel material of thread lifting suture and related devices,the advantages and preliminary achievements on spider silk were also addressed. 展开更多

Aim:The primary author previously described his technique for periareolar closure in mastopexy using a pinwheel interlocking purse string with absorbable barbed suture and now reports the results of a retrospective photometric analysis comparing this technique with the same closure using Gortex®suture.This study is designed to compare the degree of areolar widening and safety profile of using absorbable barbed sutures for periareolar closure versus permanent smooth suture.Methods:A retrospective chart review was conducted of all patients whose periareolar closures were performed using an interlocking purse-string technique over a 10-year period.Only patients undergoing circumvertical mastopexy were included.All had photometric evaluation and follow-up performed within 6-24 months.Results:In total,20 patients(40 areolas),which were closed with absorbable barbed suture,were analyzed photometrically.In this suture group,areola size increased a mean of 4.9%from baseline,and no complications(0%)were observed.This compared favorably with previously reported complication rates using permanent sutures and with a series of cases presented herein in which permanent smooth suture was used for purse string closure.The degree to which absorbable barbed suture controls areolar spread was shown to be significantly better than those where permanent smooth purse string techniques were employed.Conclusion:Circumvertical mastopexy closures using absorbable barbed suture was shown to be safe and effective and compared favorably to older techniques using permanent smooth suture for similar closures.This paper lends support to the safety of using absorbable barbed suture in circumareolar closures to limit areolar spread. 展开更多

Background Partial nephrectomy is currently the standard treatment for clinical T1 renal neoplasms, as it can provide oncologic outcomes equivalent to radical nephrectomy. The aim was to evaluate the efficacy of self-retaining suture (SRS) in renorrhaphy technique in retroperitoneal laparoscopic partial nephrectomy (LPN) for a single renal mass of moderate or high complexity by assessing peri-operative outcomes. Methods A retrospective analysis was done of 64 patients between 2010 and 2012 for complex renal mass (RENAL score 〉7) in whom retroperitoneal LPN was performed with two layers using continuous knotless barbed suture (Quill PDO SRS group; n=34) and absorbable vicryl (non-SRS group; n=30), respectively. Cases were matched for RENAL score. All the surgical procedures were performed by the same surgeon with experience of more than 500 cases of LPN. Comparisons were made in patients and preoperative outcomes and peri-operative complications between SRS group and non-SRS group. Results Mean warm ischemia time (WIT) in SRS group was less than non-SRS group (18.0 vs. 24.8 minutes, P=-0.021). Renorrhaphy suture cost in SRS group was lower than non-SRS group ($269.6 vs. $335.8, P=0,001). There were no significant differences between the two groups for postoperative changes in creatinine and estimated glomerular filtration rate and the rate of peri-operative complications. Conclusion SRS was safe for complex renal tumor with two layers, continuous and unknot suture, during LPN and would reduce the WIT and renorrhaphy suture cost significantly. 展开更多
