Double-nylon purse-string suture in closing postoperative wounds following endoscopic resection of large(≥3 cm)gastric submucosal tumors

BACKGROUND Endoscopic full-thickness resection(EFTR)of gastric submucosal tumors(SMTs)is safe and effective;however,postoperative wound management is equally important.Literature on suturing following EFTR for large(≥3 cm)SMTs is scarce and limited.AIM To evaluate the efficacy and clinical value of double-nylon purse-string suture in closing postoperative wounds following EFTR of large(≥3 cm)SMTs.METHODS We retrospectively analyzed the data of 85 patients with gastric SMTs in the fundus of the stomach or in the lesser curvature of the gastric body whose wounds were treated with double-nylon purse-string sutures after successful tumor resection at the Endoscopy Center of Renmin Hospital of Wuhan University.The operative,postoperative,and follow-up conditions of the patients were evaluated.RESULTS All tumors were completely resected using EFTR.36(42.35%)patients had tumors located in the fundus of the stomach,and 49(57.65%)had tumors located in the body of the stomach.All patients underwent suturing with double-nylon sutures after EFTR without laparoscopic assistance or further surgical treatment.Postoperative fever and stomach pain were reported in 13(15.29%)and 14(16.47%)patients,respectively.No serious adverse events occurred during the intraoperative or postoperative periods.A postoperative review of all patients revealed no residual or recurrent lesions.CONCLUSION Double-nylon purse-string sutures can be used to successfully close wounds that cannot be completely closed with a single nylon suture,especially for large(≥3 cm)EFTR wounds in SMTs.

Comparison of a modified anoscope and the purse-string anoscope in stapled haemorrhoidopexy

AIM： To compare the results of the anoscope of the PPH kit and a modified anoscope during stapled haemorrhoidopexy. METHODS： The hospital records of 37 patients who underwent stapled haemorrhoidopexy between 2001 and 2006 were reviewed. The purse-string suture anoscope in the PPH kit was used on 15 patients （Group 1）, and the modified anoscope was used on 22 patients （Group 2）. Demographic characteristics of the patients, operation time, surgeon＇s performance, analgesic requirement, and complications were compared. RESULTS： Operation time was significantly longer in Group 1 （42.0 4- 8.4 min vs 27.7 4- 8.0 min, P = 0.039）. The surgeons reported their operative performance as significantly better in Group 2 （the results of the assessments were poor in ten, medium in four and good in one in Group 1, while good in all patients in Group 2, P 〈 0.001）. The need for haemostatic sutures was significantly higher in Group 1 （six cases） and was needed in two cases in Group 2 （P = 0.034）. CONCLUSION： Operation time decreased and the surgeon＇s satisfaction increased with use of the modified anoscope, and fewer haemostatic sutures were required if the surgeon waited longer before and after firing the stapler.

Feasibility and efficacy of endoscopic purse-string suture-assisted closure for mucosal defects induced by endoscopic manipulations

BACKGROUND Large or transmural defects induced by gastrointestinal endoscopic manipulations are difficult to close,although complete closure is recommended for better recovery.Endoscopic purse-string assisted suturing(EPSS)has been used in clinical practice and has proven to be an effective and safe technique for the closure of large mucosal defects.However,details regarding the efficacy of endoscopic pre-purse-string suture(P-EPSS)are unknown,especially that it offers several advantages over conventional EPSS(C-EPSS).AIM To elucidate the outcomes of EPSS-assisted closure in different clinical situations,and evaluate the efficacy of P-EPSS.METHODS This retrospective observational study included a total of 180 patients who underwent closure assisted by P-EPSS(n=63)or C-EPSS(n=117)between July 2014 and June 2020.The P-EPSS and C-EPSS groups were compared and the intergroup differences in aspects such as the lesion size,location,and morphology,incidence of complete closure,intraoperative perforation,and delayed adverse events were evaluated.Data on the features and clinical course of cases with adverse events were collected for further analysis.RESULTS Patients with lesion size larger than 3 cm,lesions located at the fundus of stomach,or submucosal tumors originating from the deep mucosa were more likely to undergo P-EPSS-assisted closure.The P-EPSS group showed a significantly higher proportion of intraoperative perforation(56%vs 17%)and a much shorter procedure time(9.06±6.14 min vs 14.84±7.25 min).Among adverse events,the incidence of delayed perforation(5%vs 4%;P=0.82)and delayed bleeding(3%vs 4%;P=0.96)did not differ significantly between the groups.Multivariate analysis revealed that lesions with incomplete closure[odds ratio(OR)=21.33;95%confidence interval(CI):5.45-83.45;P<0.01]or size greater than 3 cm(OR=3.14;95%CI:1.08-9.18;P=0.039)showed a statistical tendency to result in an increase in delayed adverse events.CONCLUSION The present study revealed that EPSS could achieve secure complete closure of mucosal defect.PEPSS could shorten the procedure and yield complete closure of mucosal defects.Rather than closure-type selection,incomplete closure or lesion size larger than 3 cm were associated with worse outcomes.

Thirty-gauge needle-guided purse-string suture pupilloplasty:a new technique

AIM:To observe the clinical outcomes of 30-gauge(G)needle-guided 10-0 prolene suture purse-string pupilloplasty for atonic pupil management.METHODS:Eight patients with atonic pupils who underwent suture purse-string pupilloplasty were retrospectively analyzed.Preoperative data and at least 6mo of postoperative data were collected from all the patients.RESULTS:The corrected distance visual acuity(CDVA)before and after surgery was 0.58±0.22 and 0.20±0.10 logMAR,respectively(P=0.002).The pre-and postoperative pupil size was 7.38±0.88 and 3.09±0.71 mm(P=0.000),respectively.The corneal endothelial cell count was 2841±176/mm^(2) before and 2692±143/mm^(2) after surgery(P=0.000).No intraoperative or postoperative complications were reported.During the follow-up period of at least 6mo,all treated pupils were centered and generally or nearly round.Furthermore,the patients did not exhibit photophobia,glare,or diplopia.CONCLUSION:This technique is a simple and effective method for pupil reduction.

Systematic review and meta-analysis of published randomized controlled trials comparing purse-string vs conventional linear closure of the wound following ileostomy(stoma)closure

Objective:The objective of this article is to systematically analyse the randomized,controlled trials comparing the effectiveness of purse-string closure(PSC)of an ileostomy wound with conventional linear closure(CLC).Methods:Randomized,controlled trials comparing the effectiveness of purse-string closure vs conventional linear closure(CLC)of ileostomy wound in patients undergoing ileostomy closure were analysed using RevMan-,and the combined outcomes were expressed as risk ratio(RR)and standardized mean difference(SMD).Results:Three randomized,controlled trials,recruiting 206 patients,were retrieved from medical electronic databases.There were 105 patients in the PSC group and 101 patients in the CLC group.There was no heterogeneity among included trials.Duration of operation(SMD:-0.18;95%CI:-0.45,0.09;z=1.28;P<0.20)and length of hospital stay(SMD:0.01;95%CI:-0.26,0.28;z=0.07;P<0.95)was statistically similar following both approaches of ileostomy wound closure.The risk of surgical site infection(OR,0.10;95%CI:0.03,0.33;z=3.78;P<0.0001)was significantly reduced when ileostomy wound was closed using PSC technique.Conclusion:PSC technique for ileostomy wound is associated with a reduced risk of surgical site infection apparently without influencing the duration of operation and length of hospital stay.

Short-term outcomes following purse-string versus conventional closure of ileostomy wounds in Chinese colorectal cancer patients-a single center retrospective study

Background Nearly 15%colorectal cancer(CRC)patients received ileostomy,while surgical site infection(SSI)is a common complication after ileostomy wound closure.Purse-string closure was reported to reduce SSI rate in ileostomy wound closure compared with conventional linear closure,but had never been systematically reported in CRC patients.The present study aimed to compare the short-term outcomes between purse-string and conventional closure in Chinese CRC patients.Patients and methods A total of 57 CRC patients underwent ileostomy wounds closure in the Second Affiliated Hospital of Zhejiang University during November,2015 and October,2017 were retrospectively reviewed.Twenty-nine received purse-string closure while the others received conventional closure.The short-term outcomes including SSI rate,scar length,pain score and hospital stay were reviewed and analyzed.Results There were no significant differences in the characteristics of the patients between two groups.The SSI rate was similar within two groups(10.3%vs 10.7%,p=1.000).The purse-string closure group had a significantly short scar length(1.66 cm vs 5.30 cm,p<0.0001),but had no difference in operation time,hospital stay and postoperative pain.Conclusion The present study did not find superiority of Purse-string closure in SSI rate control.It seemed only had a cosmetic effect according to its shorter scar length.

Transoral outlet reduction:Outcomes of endoscopic Roux-en-Y gastric bypass revision in 284 patients at a community practice

BACKGROUND Transoral outlet reduction(TORe)is a minimally invasive endoscopic revision of Roux-en-Y gastric bypass(RYGB)for weight recurrence;however,little has been published on its clinical implementation in the community setting.AIM To characterize the safety and efficacy of TORe in the community setting for adults with weight recurrence after RYGB.METHODS This is a retrospective cohort study of argon plasma coagulation and purse-string suturing for gastric outlet reduction in consecutive adults with weight recurrence after RYGB at a single community center from September 2020 to September 2022.Patients were provided longitudinal nutritional support via virtual visits.The primary outcome was total body weight loss(TBWL)at twelve months from TORe.Secondary outcomes included TBWL at three months and six months;excess weight loss(EWL)at three,six,and twelve months;twelve-month TBWL by obesity class;predictors of twelve-month TBWL;rates of post-TORe stenosis;and serious adverse events(SAE).Outcomes were reported with descriptive statistics.RESULTS Two hundred eighty-four adults(91.9%female,age 51.3 years,body mass index 39.3 kg/m^(2))underwent TORe an average of 13.3 years after RYGB.Median pre-and post-TORe outlet diameter was 35 mm and 8 mm,respectively.TBWL was 11.7%±4.6%at three months,14.3%±6.3%at six months,and 17.3%±7.9%at twelve months.EWL was 38.4%±28.2%at three months,46.5%±35.4%at six months,and 53.5%±39.2%at twelve months.The number of follow-up visits attended was the strongest predictor of TBWL at twelve months(R^(2)=0.0139,P=0.0005).Outlet stenosis occurred in 11 patients(3.9%)and was successfully managed with endoscopic dilation.There was one instance of post-procedural nausea requiring overnight observation(SAE rate 0.4%).CONCLUSION When performed by an experienced endoscopist and combined with longitudinal nutritional support,purse-string TORe is safe and effective in the community setting for adults with weight recurrence after RYGB.

Photometric analysis of absorbable barbed suture for periareolar closure in mastopexy

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.
