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.

Case of colonic intussusception secondary to mobile cecum syndrome repaired by laparoscopic cecopexy using a barbed wound suture device

A 27-year-old man with recurrent right lower quadrant pain was admitted to our hospital. Ultrasonography and computed tomography examination of the abdomen revealed a target sign in the ascending colon, which was compatible with the diagnosis of cecal intussusception. The intussusception was spontaneously resolved at that time, but it relapsed 6 mo later. The patient underwent a successful colonoscopic disinvagination; there was no evidence of neoplastic or inflammatory lesions in the colon and terminal ileum. The patient underwent laparoscopic surgery for recurring cecal intussusception. During laparoscopy, we observed an unfixed cecum on the posterior peritoneum(i.e. a mobile cecum). Thus, we performed laparoscopic appendectomy and cecopexy with a lateral peritoneal flap using a barbed wound suture device. The patient's post-operative course was uneventful, and he continued to do well without recurrence at 10 mo after surgery. Laparoscopic cecopexy using a barbed wound suture device is a simple and reliable procedure that can be the treatment of choice for recurrent cecal intussusception associated with a mobile cecum.

Comparison of modified gunsight suture technique and traditional interrupted suture in enterostomy closure

BACKGROUND Prophylactic enterostomy surgery is a common surgical approach used to reduce the risk of anastomotic leakage in patients who have undergone partial intestinal resection due to trauma or tumors.However,the traditional interrupted suturing technique used in enterostomy closure surgery has several issues,including longer surgical incisions and higher incision tension,which can increase the risk of postoperative complications.To address these issues,scholars have proposed the use of a“gunsight suture”technique.This technique involves using a gunsight incision instead of a traditional linear incision,leaving a gap in the center for the drainage of blood and fluid to reduce the risk of infection.Building on this technique,we propose an improved gunsight suture technique.A drainage tube is placed at the lowest point of the incision and close the gap in the center of the gunsight suture,which theoretically facilitates early postoperative mobility and reduces the burden of dressing changes,thereby reducing the risk of postoperative complications.AIM To compare the effectiveness of improved gunsight suture technique with traditional interrupted suture in closing intestinal stomas.METHODS In this study,a retrospective,single-center case analysis was conducted on 270 patients who underwent prophylactic ileostomy closure surgery at the Department of Colorectal Surgery of Qilu Hospital from April 2017 to December 2021.The patients were divided into two groups:135 patients received sutures using the improved gunsight method,while the remaining 135 patients were sutured with the traditional interrupted suture method.We collected data on a variety of parameters,such as operation time,postoperative pain score,body temperature,length of hospital stays,laboratory indicators,incidence of incisional complications,number of wound dressing changes,and hospitalization costs.Non-parametric tests and chi-square tests were utilized for data analysis.RESULTS There were no statistically significant differences in general patient information between the two groups,including the interval between the first surgery and the stoma closure[132(105,184)d vs 134(109,181)d,P=0.63],gender ratio(0.64 vs 0.69,P=0.44),age[62(52,68)years vs 60(52,68)years,P=0.33],preoperative body mass index(BMI)[23.83(21.60,25.95)kg/m²vs 23.12(20.94,25.06)kg/m²,P=0.17].The incidence of incision infection in the improved gunsight suture group tended to be lower than that in the traditional interrupted suture group[(n=2/135,1.4%)vs(n=10/135,7.4%),P<0.05],and the postoperative hospital stay in the improved gunsight suture group was significantly shorter than that in the traditional interrupted suture group[5(4,7)d vs 7(6,8)d,P<0.05].Additionally,the surgical cost in the modified gunsight suture group was slightly lower than that in the traditional suture group[4840(4330,5138)yuan vs 4980(4726,5221)yuan,P>0.05],but there was no significant difference in the total hospitalization cost between the two groups.CONCLUSION In stoma closure surgery,the improved gunsight technique can reduce the incision infection rate,shorten the postoperative hospital stay,reduce wound tension,and provide better wound cosmetic effects compared to traditional interrupted suture.

Oxygen Penetration Through Full-Thickness Skin by Oxygen-Releasing Sutures for Skin Graft Transplantation

The transplantation of full-thickness skin grafts(FTSGs)is important for reconstructing skin barrier and promoting wound healing.Sufficient oxygen supply is closely related to the success of skin grafting.However,full-thickness oxygen delivery is limited by the poor oxygen permeability of skin.Oxygen-releasing sutures(O_(2)sutures)were developed to facilitate oxygen penetration through full-thickness skin.The O_(2)sutures delivered 100 times more oxygen than topical gaseous oxygen therapy at a 15 mm depth in the skin model.Under extreme hypoxia(<0.5%O_(2),v/v),O_(2)sutures could also promote endothelial cell proliferation.After the transplantation of FTSGs in mice,O_(2)sutures accelerated blood re-perfusion and increased the survival area of the skin graft.It is expected that O_(2)sutures will be adopted in clinical applications to increase the success rate of full-thickness skin transplantation.

Sulcus Transscleral Intraocular Lens Suture Fixation through Small Scleral Tunnel Incision

Purpose:To evaluate the clinical efficacy and safety of sulcus transscleral intraocular lens suture fixation with small incision through scleral tunnel in eyes the with posterior capsule defect or insufficient zonula support. Methods:Thirty nine eyes with severe posterior capsule defect and zonula damages caused by small-incision cataract surgery,and those with capsule absence or intraocular lens dislocation were selected in this investigation from February 2007 to December 2009.Sulcus transscleral intraocular lens suture combined with puncture needle-guided external approach and."one- or two-point fixation" method in the small sclera tunnel incision were employed. Results:The mean follow-up was 12.1 months (range from 3 to 28 months). Six eyes were complicated by some eye diseases postoperatively.The best-corrected visual acuity was 20/40 or better in other 34 eyes.(87.17%).All eyes with secondary IOL fixation presented equal or better naked visual acuity than best-corrected visual acuity best-corrected preoperatively.No intraoperative and postoperative complications such as hemorrhage, retinal detachment, intraocular lens tilt and decentration occurred. Conclusion:Sulcus transscleral intraocular lens suture fixation via small sclera tunnel incision was easy to operate and master,required less operative time,and made primary intraocular lens fixation more effective in eyes with posterior capsule defect or insufficient zonula support in small sclera tunnel incision surgery.In addition,the technique was safe and effcacious for secondary intraocular lens fixation.

A novel suturing technique for filtering glaucoma surgery:the accordion suture

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.

Systematic review of absorbable vs non-absorbable sutures used for the closure of surgical incisions

AIM: To report a systematic review of published randomized controlled trials(RCTs) investigating the role of absorbable suture(AS) against non-AS(NAS) used for the closure of surgical incisions.METHODS: RCTs investigating the use of AS vs NAS for the closure of surgical incisions were statistically analysed based upon the principles of meta-analysis and the summated outcomes were represented as OR.RESULTS: The systematic search of medical literature yielded 10 RCTs on 1354 patients. Prevalence of wound infection(OR = 0.97; 95%CI: 0.56, 1.69; Z = 0.11; P = 0.92) and operative morbidity(P = 0.45) was comparable in both groups. Nonetheless, the use of AS lead to lower risk of wound break-down(OR = 0.12; 95%CI: 0.04, 0.39; Z = 3.52; P < 0.0004).CONCLUSION: This meta-analysis of 10 RCTs demonstrates that the use of AS is similar to NAS for skin closure for surgical site infection and other operative morbidities. AS do not increase the risk of skin wound dehiscence,rather lead to a reduced risk of wound dehiscence compared to NAS.

Healing time of incision infection after hepatobiliary surgery treated by needle-free incision suture closure

AIM:To compare the effectiveness of needle-free incision suture closure with butterfly tape and traditional secondary suturing techniques in treating incision infection.METHODS:Two hundred and twenty-three patients with incision infection following hepatobiliary surgery at a tertiary hospital were randomly divided into three groups:90 patients were closed by needle-free incision suture closure,which gradually closed the incision wound when drainage from incision infection was visibly decreased and healthy granulation tissues had grown;79 patients were closed by butterfly bandage;another 54 patients were closed by traditional secondary suturing technique.Healing time of incision infection was calculated from the beginning of dressing change to the healing of the incision.RESULTS:Healing time in the needle-free incision suture closure group(24.2±7.2 d)was significantly shorter than that in the butterfly bandage group(33.3±11.2 d)and the traditional secondary suturing group(36.2±15.3 d)(P<0.05).Healing time in the butterfly bandage group appeared to be slightly shorter than that in the secondary suture group,but the difference was not statistically significant(P>0.05).CONCLUSION:Needle-free incision suture closure could gradually close the infection wound at the same time of drainage and dressing change,thereby shortening the healing time.

Post-urethroplasty complications in hypospadias repair: a systematic review and meta-analysis comparing, polydioxanone and polyglactin sutures

Background Polyglactin(PG)and polydioxanone(PDS)sutures are extensively used based on the surgeon's preference.The development of post-reconstruction urethrocutaneous fistula(UCF)is variably attributed to the choice of suture material for urethroplasty.This meta-an alysiscompares complications of hypospadia srepair using PGand PDS sutures.Methods The systematic review and meta-analysis were performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.The authors conducted thorough searches in databases including MEDLINE,EMBASE,CENTRAL,Scopus,Google Scholar,and clinical trial registries.Outcome measures included UCF,meatal stenosis,wound infection,urethral stricture,glans dehiscence,and overall complications.Quantitative analysis was used with fixed or random-effect models to find the pooled risk ratio and I2 heterogeneity.Results The criteria for inclusion were met by five comparative studies with the inclusion of 1244 children altogether.Pooled analysis failed to show a statistically significant difference in the incidence of meatal stenosis,urethral stricture,wound infection,and total complications using PG and PDS sutures.However,it showed a reduction in the incidence of UCF with PDS suture hypospadias repairs(risk ratio=0.66,95%Cl 0.48 to 0.92).Conclusions PDS sutures are associated with decreased incidence of UCF than PG after hypospadias repair.The incidence of meatal stenosis,urethral stricture,wound infection,and total complications was not affected by the type of suture material used for repair.Clinical implications This meta-analysis suggests decreased incidence of UCF when PDS sutures are used for hypospadias repair which may impact the choice of suturematerialforrepair.

Facile scalable one-step wet-spinning of surgical sutures with shape memory function and antibacterial activity for wound healing

Surgical suture is commonly used in clinic due to its action in accelerating the process of wound healing.However,difficultly handling in minimally invasive surgery and bacteria-induced infection usually limit its use in a wide range of applications.Here,we report a facile scalable strategy to fabricate surgical sutures with shape memory function and antibacterial activity for wound healing.Specifically,a shape memory polyurethane(SMPU)with a transition temperature(Ttrans)at 41.3℃was synthesized by adjusting the mole ratio of the hard/soft segment,and then the shape memory surgical sutures containing polyhexamethylene biguanide hydrochloride(PHMB)as a model drug for antibacterial activity were fabricated by a facile scalable one-step wet-spinning approach,in which PHMB was directly dissolved in the coagulation bath that enable its loading into the sutures through the dual diffusion during the phase separation.The prepared sutures were characterized by their morphology,mechanical properties,shape memory,antibacterial activity,as well as biocompatibility before the wound healing capability was tested in a mouse skin suture-wound model.It was demonstrated that the optimized suture is capable of both shape memory function and antibacterial activity,and promote wound healing,suggesting that the facile scalable one-step wet-spinning strategy provides a promising tool to fabricate surgical sutures for wound healing.

Antibacterial Sutures Coated with Smooth Chitosan Layer by Gradient Deposition

Owing to the significant importance in clinics,antibacterial activity is thought as one indispensable feature of the next generation of absorbable sutures.It is challenging but imperative to arm the existing absorbable sutures with antibacterial functions.The present study describes a“gradient deposition”technique to coat a continuous and smooth layer of chitosan on the surface of absorbable sutures.Specifically,chitosan solution is arranged to undergo gradient pH decline step by step while during each pH interval,the solution is allowed to stand for a predetermined period of time in order to control gradual chitosan deposition.Chitosan nanoparticles are found to be first generated on suture surface and finally developed into a smooth chitosan layer as the antibacterial surface.In vitro and in vivo results demonstrated that coating chitosan on sutures by our technique could relieve wound inflammation,stimulate collagen deposition,regenerate blood vessels,and assist tissue repairing,consequently leading to a significant enhancement of wound healing effect.This technique is highlighted with low cost,extreme convenience and excellent safety without organic solvents.Furthermore,the“gradient deposition”technique would not affect the fundamental properties of matrix and thus hold promises as a universal way for superficial antibacterial modification towards almost all the surgical implanted materials,including but not limited to absorbable sutures.
