Project description:BackgroundTo investigate the feasibility of purse string suture pancreaticojejunostomy in complete laparoscopic pancreaticoduodenectomy for patients with an undilated pancreatic duct.MethodsWe retrospectively reviewed a database of 113 patients with undilated pancreatic ducts who had undergone laparoscopic pancreaticoduodenectomy (LPD) with purse string suture pancreaticojejunostomy to analyze the perioperative outcomes.ResultsOne hundred thirteen patients underwent successful LPD. The surgery time was 353 ± 41 min, the time required for pancreaticojejunostomy was 27 ± 5 min, and the hospital stay after surgery was 16 ± 8 days. Fifteen patients suffered postoperative complications, including twelve patients with pancreatic fistula, one with bile leakage, one with gastroparesis (complicated with abdominal infection), and one with abdominal bleeding. No perioperative death occurred.ConclusionsPurse string suture pancreaticojejunostomy is safe and feasible for patients with an undilated pancreatic duct.

Project description:ObjectiveThis study aimed to investigate the optimal strategy for myomectomy for removing giant uterine fibroids when necessary in women undergoing cesarean section.MethodsThis study was retrospective in design, and assessed outcomes in 26 patients who underwent myomectomy using a "base purse-string suture" during cesarean section. The operative duration, blood loss, uterine involution, and duration of postpartum lochia were analyzed.ResultsThis suture was associated with a mean operative duration of 11.17 ± 5.36 minutes and the mean estimated blood loss was 11.15 ± 6.05 mL. The mean postpartum duration of lochia was 34.92 ± 7.55 days and there were no cases of postpartum hemorrhage. Uterine size returned to normal within 6 weeks of delivery, without any apparent defects or abnormalities in the uterine wall as shown by an ultrasonic examination.ConclusionThis novel implementation of a base purse-string suture during cesarean myomectomy for removal of giant fibroids is a simple, safe, and effective intervention that should be considered for implementation in appropriate patients.

Project description:BackgroundPurse-string suture in transanal total mesorectal excision is a key procedural step. The aims of this study were to develop an automatic skill assessment system for purse-string suture in transanal total mesorectal excision using deep learning and to evaluate the reliability of the score output from the proposed system.MethodsPurse-string suturing extracted from consecutive transanal total mesorectal excision videos was manually scored using a performance rubric scale and computed into a deep learning model as training data. Deep learning-based image regression analysis was performed, and the purse-string suture skill scores predicted by the trained deep learning model (artificial intelligence score) were output as continuous variables. The outcomes of interest were the correlation, assessed using Spearman's rank correlation coefficient, between the artificial intelligence score and the manual score, purse-string suture time, and surgeon's experience.ResultsForty-five videos obtained from five surgeons were evaluated. The mean(s.d.) total manual score was 9.2(2.7) points, the mean(s.d.) total artificial intelligence score was 10.2(3.9) points, and the mean(s.d.) absolute error between the artificial intelligence and manual scores was 0.42(0.39). Further, the artificial intelligence score significantly correlated with the purse-string suture time (correlation coefficient = -0.728) and surgeon's experience (P< 0.001).ConclusionAn automatic purse-string suture skill assessment system using deep learning-based video analysis was shown to be feasible, and the results indicated that the artificial intelligence score was reliable. This application could be expanded to other endoscopic surgeries and procedures.

Project description:PurposeThe optimal method for intracorporeal esophagojejunostomy remains unclear because a purse-string suture for fixing the anvil into the esophagus is difficult to perform with a laparoscopic approach. Therefore, this study aimed to evaluate our novel technique to fix the anvil into the esophagus.Materials and methodsThis retrospective study included 202 patients who were treated at our institution with an intracorporeal circular esophagojejunostomy in a laparoscopy-assisted total gastrectomy with a Roux-en-Y reconstruction (166 cases) or a laparoscopy-assisted proximal gastrectomy with jejunal interposition (36 cases). After incising 3/4 of the esophageal wall, a hand-sewn purse-string suture was placed on the esophagus. Next, the anvil head of a circular stapler was introduced into the esophagus. Finally, the circular esophagojejunostomy was performed laparoscopically. The clinical characteristics and surgical outcomes were evaluated and compared with those of other methods.ResultsThe average operation time was 200.3 minutes. The average hand-sewn purse-string suturing time was 6.4 minutes. The overall incidence of postoperative complications (Clavien-Dindo classification grade ≥II) was 26%. The number of patients with an anastomotic leakage and stenosis at the esophagojejunostomy site were 4 (2.0%) and 12 (6.0%), respectively. All patients with stenosis were successfully treated by endoscopic balloon dilatation. There was no mortality. Regarding the materials and devices for anvil fixation, only 1 absorbable thread was needed.ConclusionsOur procedure for hand-sewn purse-string suturing with the double ligation method is simple and safe.

Project description:ObjectiveTo compare the short-term results of classic single-layer uterine closure and double-layer purse-string uterine closure (Turan technique) techniques in cesarean section in terms of the incidence of ischiocele formation.Materials and methodsThis was a prospective randomized controlled trial study. Participants undergoing first-time cesarean delivery were randomized into two groups. Fifty-eight participants were included in the double-layered uterine closure group (study group), while 53 participants were randomized into the classical single-layered uterine closure group (control group). For comparison of isthmocele formation, transvaginal ultrasound examination was planned in all patients 6 weeks after surgery. The operation data,the formation of isthmocele, its dimensions and volume were recorded.ResultsA total of 111 women were included in the study. The incidence of ischiocele at 6 weeks after birth was not significantly different between the groups (p=0.128). Isthmosel was detected in 20.8% of single-layer closures, and this rate was determined as 10.3% in the purse technique. In the Kerr incision made during surgery, the uterine incision size did not differ in either group, but the uterine incision length after suturing was significantly smaller in the purse technique compared with the other group (p<0.001).ConclusionThe incidence of ischiocele formation after cesarean section and the depth of the ischiocele was independent of the uterotomy closure technique.

Project description:Background:Opinion is divided on the optimal technique of skin closure after stoma reversal as most conventional techniques compromise either on speed/neatness of wound apposition or on the incidence of surgical site infection (SSI). Evidence suggests that purse-string skin closure (PSSC) may achieve both objectives. This study aims to compare conventional primary closure (PC) with PSSC to determine the efficacious technique for stoma wound closure. Methods:Patients undergoing stoma reversal between April 2015 and September 2017 were prospectively studied. Patients were divided into two groups based on the technique of skin closure (PC or PSSC). The following parameters were assessed: SSI, hospital stay, additional outpatient visit, wound healing time and patient satisfaction based on a standardised questionnaire. Results:Forty one patients underwent stoma reversal (20 PSSC vs 21 PC). Wound infection, need for wound care, length of hospital stay, healing time and scar size were significantly less, whereas average patient wound satisfaction scores were significantly more in the PSSC group. Conclusion:Purse-string skin closure (PSSC) proves efficacious and hence merits adoption as the technique of choice for closure of stoma wounds.

Project description:The external anal sphincter (EAS) may be injured in 25-35% of women during the first and subsequent vaginal childbirths and is likely the most common cause of anal incontinence. Since its first description almost 300 years ago, the EAS was believed to be a circular or a "donut-shaped" structure. Using three-dimensional transperineal ultrasound imaging, MRI, diffusion tensor imaging, and muscle fiber tracking, we delineated various components of the EAS and their muscle fiber directions. These novel imaging techniques suggest "purse-string" morphology, with "EAS muscles" crossing contralaterally in the perineal body to the contralateral transverse perineal (TP) and bulbospongiosus (BS) muscles, thus attaching the EAS to the pubic rami. Spin-tag MRI demonstrated purse-string action of the EAS muscle. Electromyography of TP/BS and EAS muscles revealed their simultaneous contraction and relaxation. Lidocaine injection into the TP/BS muscle significantly reduced anal canal pressure. These studies support purse-string morphology of the EAS to constrict/close the anal canal opening. Our findings have implications for the effect of episiotomy on anal closure function and the currently used surgical technique (overlapping sphincteroplasty) for EAS reconstructive surgery to treat anal incontinence.

Project description:Intracorporeal esophagojejunostomy after laparoscopic total gastrectomy is technically difficult because this procedure should be performed in a narrow surgical field in the upper abdomen even when completely laparoscopic approaches are used. The placement of the anvil of a circular stapling device into the esophagus and connection the instrument to the anvil are extremely difficult steps in this surgery. Therefore, we developed a simple technique for intracorporeal esophagojejunostomy using hemi-double stapling technique; we named this technique the efficient purse-string stapling technique (EST). More recently, we have developed a modified EST (mEST) that utilizes a new stainless steel anvil rod instead of a plastic rod. Relative to the plastic rod, the steel rod is reusable and shorter; thus, it was easier to perform anvil placement into the esophagus with the steel rod. Anvil preparation for mEST: a stainless steel rod is attached to the shaft of the anvil, and the needle and thread are sutured to the tip of the rod. After complete insertion of the anvil into the esophageal cavity, the needle and thread are used to penetrate the anterior esophageal wall, and the esophagus is then clamped using a linear stapler just distal to the site penetrated by the thread. The linear stapler is fired, and anvil placement in the esophagus is simultaneously accomplished. After the rod is removed from the anvil, the instrument is intracorporeally connected to the anvil and then fired to complete the gastrojejunostomy. This technique is simple and facilitates intracorporeal reconstruction procedures in laparoscopic total gastrectomy.
