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.

Endovascular technique using a snare and suture for retrieving a migrated peripherally inserted central catheter in the left pulmonary artery

We report a successful endovascular technique using a snare with a suture for retrieving a migrated broken peripherally inserted central catheter(PICC)in a chemotherapy patient.A 62-year-old male received monthly chemotherapy through a central venous port implanted into his right subclavian area.The patient completed chemotherapy without complications 1 mo ago;however,he experienced pain in the right subclavian area during his last chemotherapy session.Computed tomography on that day showed migration of a broken PICC in his left pulmonary artery,for which the patient was admitted to our hospital.We attempted to retrieve the ectopic PICC through the right jugular vein using a gooseneck snare,but were unsuccessful because the catheter was lodged in the pulmonary artery wall.Therefore,a second attempt was made through the right femoral vein using a snare with triple loops,but we could not grasp the migrated PICC.Finally,a string was tied to thetop of the snare,allowing us to curve the snare toward the pulmonary artery by pulling the string.Finally,the catheter body was grasped and retrieved.The endovascular suture technique is occasionally extremely useful and should be considered by interventional cardiologists for retrieving migrated catheters.

Clinical Analysis on the Effectiveness of Conservative Compression Suture Technique to Conserve Fertility on Pernicious Placenta Previa

Objective: To evaluate the effectiveness of conservative compression surgical suture techniques used for the management of pernicious placenta previa to conserve fertility in the subsequent pregnancies. Study Design: This was a non-comparative retrospective study of 188 patients diagnosed with pernicious placenta previa who underwent cesarean section in The First Hospital of Jilin University, China, from 1 January 2013 to 1 January 2018. Successful group was defined as those in which the intraoperative bleeding was managed by either modified CHO or by B-lynch suture technique and those who had further intervention including hysterectomy were designated as failure group. Results: Out of 217 patients, 188 met inclusion criteria and 29 patients were excluded. In 188 cases, 183 (97.34%) cases successes and 5 (2.65%) cases had hysterectomy. Among included group, 118 patients (62.76%) had undergone emergency cesarean section and 70 patients (37.23%) underwent elective cesarean section. The emergency group had significantly lesser gestation period of gestation at the time of cesarean section (P = 0.021) and lower neonatal weight (P = 0.001) than that of elective group. The estimated blood loss during surgery was 500 - 3200 ml (mean: 925 ml). Additionally, the amount of bleeding was found to be significantly more in patient with intraoperative complication (P = 0.007) and in patient with implanted placenta (P 0.001). Conclusion: The conservative compression suture technique including modified CHO and B-lynch suture technique during the cesarean delivery is a feasible, safe and effective alternative conservative surgical technique for the management of bleeding in case of pernicious placenta previa. Besides good surgical outcome and proper neonatal result this technique also reduces the rate of hysterectomy, thus conserving the fertility.

Cauterization technique for suture erosion in transscleral fixation of intraocular lenses

Transscleral suturing is a commonly applied technique to fix intraocular Implants in the sulcus.A major problem after transscleral implantation is suture erosion that normally happens in the late post-surgery period and may result In an Increased incidence of endophthalmitis.Here we describe an original cauterization method by using a glass rod to melt the exposed suture end without damaging the suture knot in the sclera to avoid suture exposure in sclera-fixed IOL implantation.This is a simple,quick and effective technique that can be performed without conjunctiva incisions and will help to reduce suture erosion related complications.

The Optimal Suture Technique for Mitral Valve Replacement in an <i>Ex Vivo</i>Animal Model

Objective: This study compared and evaluated three suture methods in order to find the method with the best durability for mitral valve replacement. The methods evaluated are horizontal mattress suture with subanular pledgets, horizontal mattress suture with supraanular pledgets and continuous running suture. Methods: Thirty hearts were explanted from newly terminated pigs. The hearts were randomized in the three groups. After an atriotomy, the mitral valve was cut out, and a patch was sutured into its place. An air pump model was connected to a balloon which was placed in the left ventricle through aorta and continuously filled with air to a maximum of 300 mmHg. The peak pressure at rupture was noted. If no rupture occurred before reaching 300 mmHg, the suture was found competent. Results: Two out of ten hearts in the continuous running suture-group had myocardial rupture within a pressure of 300 mmHg. In the remaining eight hearts there were no ruptures within 300 mmHg. In the two groups sutured with horizontal mattress with pledgets placed either subanular or supraanular, no rupture of myocardium occurred. When comparing continuous running suture with the horizontal mattress with subanular pledgets or the horizontal mattress with supraanular pledgets, the 1-sided Fishers’ exact was 0.237. At 5% significance level, there was no difference between the three suture methods. Conclusion: There was no statistically significant difference between the durability of the three suture methods, though rupture was only evident in the continuous running suture line. Since it is the surgeon’s choice to select the optimal suture technique, our study should be a reminder for the surgeon to reflect on the suturing factors that have an influence on successful mitral valve replacement.

A standardized technique for safe pancreaticojejunostomy:Pair-Watch suturing technique

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.

Looped,Broad,and Deep Buried Suturing Technique for Wound Closure

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.

Novel suturing technique,based on physical principles,achieves a breaking point double that obtained by conventional techniques

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).

Treatment of Keloids in A Child with Surgery Alone:Clinical Application of the LBD Suturing Technique

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.

Can trans-anal reinforcing sutures after double stapling in lower anterior resection reduce the need for a temporary diverting ostomy?

AIM:To evaluate trans-anal reinforcing sutures in low anterior resection using the double-stapled anastomosis technique for primary rectal cancers performed at a single institution.METHODS:The data of patients who received transanal reinforcing sutures were compared with those of patients who did not receive them after low anterior resection.Patients who underwent laparoscopic low anterior resection and the double-stapled anastomosis technique for primary rectal cancer between January2008 and December 2011 were included in this study.Patients with no anastomosis,a hand-sewn anastomosis,high anterior resection,or preoperative chemoradiation were excluded.The primary outcomes measured were the incidence of postoperative anastomotic complications and placement of a diverting ileostomy.RESULTS:Among 110 patients,the rate of placement of a diverting ileostomy was significantly lower in the suture group(SG)compared with the non-suture control group(CG)[SG,n=6(12.8%);CG,n=19(30.2%),P=0.031].No significant difference was observed in the rate of anastomotic leakage[SG,n=3(6.4%);CG,n=5(7.9%)].CONCLUSION:Trans-anal reinforcing sutures may reduce the need for diverting ileostomy.A randomized prospective study with a larger population should be performed in the future to demonstrate the efficacy of trans-anal reinforcing sutures.

Facial Asymmetry Correction in Facial Palsy Patients with Silhouette Sutures

Introduction: over the last few decades several techniques static and dynamics, have been performed to improve facial asymmetry and functionality alter suffering facial paralysis. Methods: we present a pilot study to show and evaluate the benefits of a new form of facial suspension, with Silhouette sutures. We performed two patients with total and complete facial palsy due to otical tuberculosis in one case and to parotid carcinoma in the other. Results: one year after surgery, both patients have improved facial asymmetry, mastication and speech production which have lead to a higher self-esteem and major social interaction. Conclusions: static facial suspension with Silhouette sutures is a non invasive alternative to dynamic techniques in patients who don’t want or can’t undergo more complex surgeries.

Prospective Interventional Study to Quantify Barbed Suture Exposure at Vaginal Vault and Assess Post-Operative Risk

Background: The use of barbed suture in laparoscopic surgery is increasing ever since 2008. Published reports of use of unidirectional barbed suture for vaginal vault closure following total laparoscopic hysterectomy (TLH), indicates it is safe. Despite of this many reports of adhesions and bowel obstruction are reported. This complication was never assessed in relation to amount of suture exposure at vaginal vault. We thought of quantifying the barbed suture exposure at vaginal vault and assess the risk of post-operative complications. Objective: The objective was to quantify the exposure of barbed suture at vaginal vault by adopting a uniform technique of vault suturing and assessing postoperative risk related to adhesions at vaginal vault. Method: In 30 patients who underwent TLH, a uniform new technique of vaginal vault closure using barbed suture was used and the portion of suture exposed at vaginal vault was quantified. The patients were followed up for a period of 6 months to assess post-operative risk of adhesions at vault and sequalae. Result: Mean length of suture exposed was 2.64 ± 1.65 mm only. Suture exposure at vaginal vault was seen in 23 (76.67%) out of 30 patients. The suture was exposed on average at 1.57 ± 1.20 places at vaginal vault. Conclusion and Recommendations: The study with an accepted relative error of 5% quantifies barbed suture exposure at vaginal vault. We had adopted a uniform new method of vaginal vault suturing to study and to quantify barbed suture exposure. It was observed that very minimal portion of suture was exposed at vaginal vault. It was exposed at only a couple of places at vaginal vault. Thus, decreasing suture exposure at vaginal vault will reduce its exposure related risk.

Efficacy of staple line reinforcement by barbed suture for preventing anastomotic leakage in laparoscopic rectal cancer surgery

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.

Using Zhang’s supertension-relieving suture technique with slowly-absorbable barbed sutures in the management of pathological scars:a multicenter retrospective study

Background:An ideal tension-relieving suture should be efficient for>3 months to retrieve normal tensile strength.Most preexisting suturing techniques provided tension elimination followed by relapse and scar proliferation due to absorption and cut-through of the sutures.This study introduces a simple but effective suture technique developed by a senior author(ZYX)to solve this problem.Methods:A total of 120 patients with pathological scar(PS)had intervention treatment with the proposed suturing strategy at three centers from January 2018 to January 2021.A slowly absorbable 2-0 barbed suturewas used for subcutaneous tension relieving with a set-back from the wound edge and a horizontal interval between proposed inserting points of 1 cm.The Patient and Observer Scar Assessment Scale(POSAS),scar width,perfusion and eversion of the wound edge were evaluated at 3-,6-and 12-month follow-up.The time needed to place the tension-relieving suture was recorded and relapse was monitored for 18 months postoperatively.Results:In total,76 trunks,32 extremities and 12 cervical PS were included,with an average subcutaneous tension-relieving suture time of 5 min.The Patient and Observer Scar Assessment Scale(POSAS)score decreased from 84.70±7.06 preoperatively to 28.83±3.09,26.14±1.92 and 24.71±2.00 at 3,6 and 12 months postoperatively,respectively(p<0.0001).The scar widths were 0.17±0.08,0.25±0.09 and 0.33±0.10 cm,respectively,with perfusion significantly decreased from 213.64±14.97 to 112.23±8.18 at 6 months(p<0.0001).The wound edge flattened out during the first 3 months in most cases with only two scar relapses.Conclusions:Zhang’s suture technique provides a rapid and long-lasting tension-relieving effect with ideal scar appearances and lower relapse rates in the surgical management of PS.
