Objective: To investigate the effects of barbed and conventional sutures on reproductive outcomes and ovarian reserve after laparoscopic treatment for benign non‐endometrioma ovarian cysts. Methods: This retrospective study was conducted at an affiliated women's hospital between May 2017 and December 2019. Patients with benign non‐endometriotic ovarian cysts undergoing laparoscopic cystectomy were included. Results: Patients received barbed sutures (221 patients) or conventional smooth sutures (203 patients) intraoperatively. The two groups had comparable baseline characteristics. The surgical duration and ovarian suturing time were significantly shorter in the barbed suture group than in the conventional smooth suture group (P < 0.001 and P = 0.002, respectively). The rate of postoperative hemoglobin decline and serum anti‐Müllerian hormone decline were similar between the two groups (P > 0.05). A total of 316 (74.53%) patients experienced at least one pregnancy postoperatively: 170 (76.92%) and 146 (71.92%) patients in the barbed suture and conventional smooth suture groups, respectively (χ2 = 1.395, P = 0.238). Multivariate Poisson regression demonstrated that barbed sutures had no significant effect on the overall postoperative pregnancy rate (adjusted incidence rate ratio, 1.10; 95% confidence interval, 0.93–1.36; P = 0.382). Conclusion: In patients with benign non‐endometriotic ovarian cysts undergoing laparoscopic ovarian cystectomy, barbed sutures had a reproductive outcome similar to that of conventional smooth sutures while providing higher surgical efficiency without adverse effects on the postoperative ovarian reserve. Barbed sutures are probably a viable option to conventional smooth sutures. Synopsis: The reproductive outcome of barbed sutures was similar to that of conventional smooth sutures in patients with benign non‐endometriotic ovarian cysts undergoing laparoscopic ovarian cystectomy.

Purpose: Mastering intracorporeal suturing is challenging in the evolution from conventional to laparoscopic bariatric surgery. Among various techniques competing for superiority in overcoming this hurdle, we focus on exploring the potential of barbed sutures through a meta-analysis that compares outcomes to those of conventional non-barbed sutures in bariatric surgery. Materials and Methods: We conducted a comprehensive search on PubMed, Scopus, and Embase to identify studies comparing barbed sutures with non-barbed sutures in bariatric surgeries, focusing on outcomes such as operative time, suturing time, postoperative complications, and hospital stay. The statistical analysis was carried out using RStudio version 4.3.2. Heterogeneity was assessed using the Cochrane Q test and I2 statistics. Results: Incorporating data from 11 studies involving a total of 27,442 patients, including 3,516 in the barbed suture group across various bariatric surgeries, our analysis demonstrates a significant reduction in suturing time (mean difference -4.87; 95% CI -8.43 to -1.30; p < 0.01; I2 = 99%) associated with the use of barbed sutures. Specifically, in Roux-en-Y gastric bypass, we observed a significant decrease in operative time (mean difference -12.11; 95% CI -19.27 to -4.95; p < 0.01; I2 = 93%). Subgroup analyses and leave-one-out analyses consistently supported these findings. Furthermore, we found that the mean body mass index did not significantly predict the mean difference in operative time outcome. No significant differences emerged in hospital stay or postoperative complications, including leak, bleeding, stenosis, and bowel obstruction (p > 0.05). Conclusion: Our study findings address barbed sutures as a potential alternative for laparoscopic intracorporeal suturing in bariatric surgery. [ABSTRACT FROM AUTHOR]

Objective: A chest tube is usually placed in patients undergoing general thoracic surgery. Although the barbed suture method has been introduced for chest tube wound closure, its superiority to the conventional suture methods for drain management remains unclear. The study aimed to determine whether the barbed suture method could reduce drain-related adverse events compared to the conventional method. Methods: We retrospectively reviewed the medical records of patients who underwent general thoracic surgery between January 2021 and December 2022, 1 year before and after the introduction of the barbed suture method at our institution. Patients who underwent the barbed suture or conventional method were included. Univariate and multivariate analyses of drain-related adverse events were performed. Results: Of the 250 participants, 110 and 140 underwent the barbed suture method and conventional suture method, respectively. The univariate analysis showed that a higher body mass index, preoperative malignant diagnosis, lobectomy, longer operative time, larger tube size, longer chest drainage duration, surgical complications, and conventional method were risk factors for drain-related adverse events. The multivariate analysis showed that the barbed suture method was a protective factor against drain-related adverse events (odds ratio 0.267; 95% confidence interval 0.103–0.691; P = 0.007). Conclusions: The barbed suture method could reduce drain-related adverse events compared to the conventional method. Therefore, it might be a potential standard method for chest tube wound closure in patients undergoing general thoracic surgery. [ABSTRACT FROM AUTHOR]

Background: For abdominal fascial closure, the choice of optimal suture material and appropriate suture technique are of paramount importance to prevent the incidence of incisional hernia. Although barbed sutures are widely used in various surgical fields, their safety and feasibility on abdominal fascial closure which requires the most tensile strength for security have not been established yet. Methods: We conducted a prospective, single‐arm, interventional clinical trial to present the postoperative outcomes of using barbed sutures in abdominal fascial closure between April 2021 and August 2021. Patients with colorectal cancer who underwent minimally invasive surgery in elective setting were included. For all participants, monofilament polydioxanone barbed suture, MONOFIX®, was used to secure the abdominal fasica. The primary outcome was the 1‐year incidence of incisional hernia assessed by computed tomography. Results: A total of 30 patients were included. The median fascial incision length and suture length were 6.5 cm (range, 6–7.5 cm) and 31 cm (range, 27.5–39.0 cm), respectively. The median procedure time of abdominal fascial closure was 4 min (range, 3–9 min). There was no incidence of unexpected event related to suturing including suture cutting, stopper separation from threads, and suture loosening. One case of superficial surgical site infection occurred during postoperative hospital stays. There was no fascial dehiscence, incisional hernia, and adhesive ileus during a median follow‐up period of 17.5 months. Conclusion: Monofilament polydioxanone barbed suture, MONOFIX®, may be used safely and effectively on abdominal fascial closure. Clinicaltrials.gov number: NCT05872334. [ABSTRACT FROM AUTHOR]

This study aimed to compare the tissue damage caused by barbed sutures and conventional sutures using scanning electron microscopy (SEM). porcine myocardium was incised and sutured using different thread types: barbed suture, (STRATAFIX® Spiral PDS PLUS) and conventional sutures, (VICRYL® and PDS Plus®). Needle hole shapes were examined at magnifications of 30x-100x. VICRYL® suture damaged the tissue and created large gaps around the needle holes. The tissue around the needle holes was smoother and less damaged in the single suture ligations with PDS®; however, a large gap had formed. In the continuous suture with STRATAFIX®, the tissue around the needle holes was significantly smoother and minimally damaged, with no noticeable gaps around the needle holes. Barbed sutures reduced the load on needle holes and minimised tissue damage owing to the dispersion of traction forces by the barbs compared with conventional sutures. [ABSTRACT FROM AUTHOR]

Simple Summary: Inguinal hernias (IHs) occur uni- or bilaterally when intestinal loops enter the vaginal ring (VR), exiting the abdominal cavity. They are a relatively common problem in foals and mature horses, mostly affecting intact male animals. In stallions (acquired hernias), the clinical scenario presents with colic and is an emergency, life-threatening condition, while in foals (congenital hernias), conservative management could be carried out. However, surgical treatment may be necessary as a preventive or therapeutic measure to close the VR. Several laparoscopic techniques have been reported, each with different results and postoperative complications. This retrospective study describes the results using barbed sutures. Barbed sutures are characterized by the presence of "barbs" along their length, which provide better tissue engagement and eliminate the need for knots, which is a great advantage in minimally invasive surgery. This technique was applied to 40 animals, successfully closing a total of 59 VRs. Barbed sutures were used alone or in combination with other techniques, and postoperative follow-up data was gathered from owners and/or referring veterinarians. This multicentric retrospective study suggests that laparoscopic hernioplasty using barbed sutures is a safe and effective method for the treatment and prevention of inguinal hernias in horses. Inguinal hernias (IHs) and ruptures are a relatively common condition in horses, occurring in foals (congenital) and adult (acquired) animals. A retrospective observational analysis was conducted on 40 cases that underwent laparoscopic surgery to close the VRs using barbed sutures alone or combined with other techniques. Signalment, clinical presentation, surgery, and follow-up data were obtained. In total, fifty-nine VRs were closed using barbed sutures (alone or in combination with other methods), with six cases performed prophylactically and forty-four due to acquired IH. Of the forty-four cases with IH, four were non-strangulated hernias, while thirty presented with strangulated small intestines (twenty-eight acquired and two congenital). The results obtained in this study suggest that laparoscopic hernioplasty with barbed sutures is an effective and safe surgical procedure that could be recommended as a standard practice for managing inguinal hernias in horses, particularly when sparing testicles or preserving reproductive capabilities is a priority.

Purpose: Barbed sutures are tissue control devices that can reduce operating room time and costs. We analyzed the utility of barbed sutures in posterior spinal surgery in order to prove non-inferiority to conventional methods for wound closure. Methods: A cohort of patients undergoing elective posterior spinal surgery in which barbed (prospective) versus conventional sutures (retrospective) were used was analyzed. The primary endpoint was the occurrence of wound healing complications or the need for surgical revision. Secondary endpoints included postoperative stay, readmission rate, and duration and cost of wound closure. Result: A total of 483 patients participated in the study, 183 in the Barbed group and 300 in the Conventional group. Wound dehiscence or seroma occurred in 3.8% and 2.7% of the Barbed and Conventional groups, respectively (p = 0.6588). Both superficial (1.6% versus 4.0%, P = 0.2378) and deep infections (2.7% versus 4.7%, p = 0.4124) occurred similarly in both groups. Overall, the rate of re-intervention due to wound healing problems was also similar (4.9% versus 5.3%, p = 0.9906), as well as, total median hospital stay, postoperative stay and 30-day re-admission rates. The average duration of wound closure (1.66 versus 4.16 min per level operated, p < 0.0001) strongly favored the Barbed group. The mean cost of wound closure per patient was higher in the Barbed group (43.23 € versus 22.67 €, p < 0.0001). Conclusions: In elective posterior spinal procedures, the use of barbed sutures significantly reduced the duration of wound closure. The wound healing process was not hindered and the added cost related to the suture material was small. [ABSTRACT FROM AUTHOR]

The primary objective of this study was to compare time efficiency and complication rates between smooth monofilament suture (SMS) and barbed suture (BS) using the three-layer continuous incisional closure pattern after ovariohysterectomy in a high-quality high-volume spay/neuter clinic. The study was designed as a randomized controlled trial enrolling 71 adult female dogs. Dogs were randomly assigned to SMS or BS treatments. The effect of closure with BS or SMS on closure time was tested through multilevel, multivariable linear regression in a generalized linear mixed model. Body condition score, weight, and pre-closure incision length were tested as covariates. Surgeon was included in the model as a random effect. Preclosure incision length (p = 0.01) and method (p = 0.0001) were associated with closure time. Adjusting for pre-closure incision length, the average time for closure with SMS was 6.5 min (range 3.70-10.31 min), and the average time for closure with BS was 4.91 min (range 3.05-8.05 min). Accounting for the closure method, the closure time increased by 39 s for each additional centimeter of incision length. BS was more efficient than SMS when performing the three-layer continuous suture pattern. No short-term telemedicineassessed complications were noted with either treatment method. BS can improve efficiency in surgical closures, especially considering large volumes of animals, and appears to have a similar short-term, telemedicine-assessed complication rate when compared to SMS.

Purpose: One of the most challenging tasks in laparoscopic gynecological surgeries is suturing. Knotless barbed sutures are intended to enable faster suturing and hemostasis. We carried out a meta-analysis to compare the efficacy and safety of V-Loc™ barbed sutures (VBS) with conventional sutures (CS) in gynecological surgeries. Methods: We systematically searched PubMed and EMBASE for studies published between 2010 and September 2021 comparing VBS to CS for OB/GYN procedures. All comparative studies were included. Primary analysis and subgroup analyses for the different surgery and suturing types were performed. Primary outcomes were operation time and suture time; secondary outcomes included post-operative complications, surgical site infections, estimated blood loss, length of stay, granulation tissue formation, and surgical difficulty. Results were calculated as weighted mean difference (WMD) or risk ratio (RR) and 95% confidence intervals (CI) with a random effects model, and a sensitivity analysis for study quality, study size, and outlier results was performed. PROSPERO registration: CRD42022363187. Results: In total, 25 studies involving 4452 women undergoing hysterectomy, myomectomy, or excision of endometrioma. VBS were associated with a reduction in operation time (WMD – 17.08 min; 95% CI – 21.57, – 12.59), suture time (WMD – 5.39 min; 95% CI – 7.06, – 3.71), surgical site infection (RR 0.26; 95% CI 0.09, 0.78), estimated blood loss (WMD – 44.91 ml; 95% CI – 66.01, – 23.81), granulation tissue formation (RR 0.48; 95% CI 0.25, 0.89), and surgical difficulty (WMD – 1.98 VAS score; 95% CI – 2.83, – 1.13). No difference between VBS and CS was found regarding total postoperative complications or length of stay. Many of the outcomes showed high heterogeneity, likely due to the inclusion of different surgery types and comparators. Most results were shown to be robust in the sensitivity analysis except for the reduction in granulation tissue formation. Conclusion: This meta-analysis indicates that V-Loc™ barbed sutures are safe and effective in gynecological surgeries as they reduce operation time, suture time, blood loss, infections, and surgical difficulty without increasing post-operative complications or length of stay compared to conventional sutures.

Objectives: Seroma represents the most prevalent postoperative complication following laparoscopic inguinal hernia repair, particularly in the case of large inguinoscrotal hernias. This randomized controlled trial was undertaken with the objective of assessing the effects of internal orifice narrowing achieved by suturing the divided distal hernia sac in laparoscopic repair of indirect inguinoscrotal hernias. Methods: A total of 58 patients aged 18 years or older, were randomized into two groups: Group I, which underwent internal orifice narrowing, and Group II, which served as the control without narrowing. The study's primary endpoint was the incidence and volume of seroma in the inguinal region on postoperative days 1 and 7, as well as at 1, 3, and 6 months following the procedure. Secondary outcomes encompassed metrics like total operative time, acute and chronic pain levels, duration of hospital stay, recurrence rates, and the occurrence of any additional complications. Results: In comparison to the control group, the experimental group exhibited a significantly lower incidence of seroma formation at 7 days (P = 0.001). Furthermore, the ultrasonic assessment indicated a reduced seroma volume in the operative group on postoperative day 7 (8.84 ± 17.71 vs. 52.39 ± 70.78 mL; P < 0.001). Acute pain levels and hospital stay were similar between the two groups (1.22 ± 0.76 vs. 1.04 ± 0.53, P = 0.073; 1.22 ± 0.07 vs. 1.19 ± 0.08, P = 0.627, respectively). Notably, neither chronic pain nor early recurrence, nor any other postoperative complications were observed in either group throughout the follow-up period, which extended for at least 6 months (range: 6–18 months). Conclusion: In the context of laparoscopic inguinoscrotal hernia repair, the incidence and volume of seroma can be significantly reduced through the implementation of internal orifice narrowing achieved by suturing the divided distal hernia sac. And, this reduction in seroma formation was not associated elevation in postoperative pain levels or recurrence rates. [ABSTRACT FROM AUTHOR]

The barbed repositioning pharyngoplasty surgical technique is becoming more widely used for patients with obstructive sleep apnea due to its safety, effectiveness, and rapidity, as evidenced by multicenter studies and Meta‐analyses. In order to achieve uniform surgical outcomes, avoid errors that could worsen outcomes, and enable adequate data comparison, a standardized procedure is required to overcome surgeon‐related variability. The aim of this paper is to provide practical tips and tricks based on our surgical practice that can make the surgeon's work easier and aid in achieving desired outcomes. [ABSTRACT FROM AUTHOR]

Introduction We present a case of small intestinal obstruction due to a barbed suture used for peritoneal closure during robot‐assisted laparoscopic sacrocolpopexy. Case presentation A female patient with pelvic organ prolapse underwent robot‐assisted laparoscopic sacrocolpopexy uneventfully. Intestinal obstruction developed on postoperative Day 4. Conservative treatment with the ileus tube failed to improve abdominal symptoms. The laparoscopic examination on postoperative Day 14 revealed the barbed suture entangled with the small intestinal mesentery. The tail of the barbed suture was laparoscopically detached from the mesentery without damaging the small intestine. The tail of the barbed suture was trimmed; an antiadhesive material was applied to the peritoneal closure line and the trimmed tail of the barbed suture. Conclusion We recommend the use of conventional absorbable sutures in the peritoneal cavity because of the potential risk of intestinal obstruction caused by the barbed suture.

Abstract Laparoscopic hysterectomy is a commonly performed procedure. However, one high-risk complication is vaginal cuff dehiscence. Currently, there is no standardization regarding thread material or suturing technique for vaginal cuff closure. Therefore, this study aimed to compare extracorporeal and intracorporeal suturing techniques for vaginal cuff closure using a pelvic trainer model. Eighteen experts in laparoscopic surgery performed vaginal cuff closures with interrupted sutures using intracorporeal knotting, extracorporeal knotting and continuous, unidirectional barbed sutures. While using an artificial tissue suturing pad in a pelvic trainer, experts performed vaginal cuff closure using each technique according to block randomization. Task completion time, tension resistance, and the number of errors were recorded. After completing the exercises, participants answered a questionnaire concerning the suturing techniques and their performance. Experts completed suturing more quickly (p

Laparoscopic hysterectomy is a commonly performed procedure. However, one high-risk complication is vaginal cuff dehiscence. Currently, there is no standardization regarding thread material or suturing technique for vaginal cuff closure. Therefore, this study aimed to compare extracorporeal and intracorporeal suturing techniques for vaginal cuff closure using a pelvic trainer model. Eighteen experts in laparoscopic surgery performed vaginal cuff closures with interrupted sutures using intracorporeal knotting, extracorporeal knotting and continuous, unidirectional barbed sutures. While using an artificial tissue suturing pad in a pelvic trainer, experts performed vaginal cuff closure using each technique according to block randomization. Task completion time, tension resistance, and the number of errors were recorded. After completing the exercises, participants answered a questionnaire concerning the suturing techniques and their performance. Experts completed suturing more quickly (p < 0.001, p < 0.001, respectively) and with improved tension resistance (p < 0.001, p < 0.001) when using barbed suturing compared to intracorporeal and extracorporeal knotting. Furthermore, the intracorporeal knotting technique was performed faster (p = 0.04) and achieved greater tension resistance (p = 0.023) compared to extracorporeal knotting. The number of laparoscopic surgeries performed per year was positively correlated with vaginal cuff closure duration (p = 0.007). Barbed suturing was a time-saving technique with improved tension resistance for vaginal cuff closure. [ABSTRACT FROM AUTHOR]

Purpose: The choice of wound closure material may influence the clinical outcomes of intra-oral incision closure. Studies evaluating the application of barbed suture in the oral cavity are scarce. Hence, the present study was carried out with the aim to monitor and compare the efficacy and ease of handling of monofilament polyglycolide caprolactone (PGCL) unidirectional barbed and non-barbed sutures used for intra-oral incision closure in patients undergoing transalveolar extraction of impacted mandibular third molar and mandible fracture open reduction internal fixation. Methods: A prospective randomized open label study was carried out among subjects requiring intra-oral incision closure following mandibular third molar extraction and isolated mandible fracture fixation. The difficulty index of the impacted third molars was evaluated pre-operatively. Subjects were randomized to receive either 3–0 monofilament PGCL unidirectional barbed or non-barbed sutures. Incision closure time and ease of suture handling were recorded intra-operatively. Post-operatively, patients were monitored for incision healing using the Hollander wound evaluation scale (HWES) and intensity of pain using visual analog scale (VAS) on post-operative days 1, 3 and 7. Data analysis involved descriptive statistics, Chi-square, unpaired t test and multivariate analysis using the IBM SPSS-PC software (v.25.0). Results: A total of 60 subjects completed the study protocol, who were randomized into two groups (n1 = n2 = 30), comparable in terms of age, gender and treatment (TAE = 51; ORIF = 9) received. The incision healing outcomes were significantly better (p = 0.016) with barbed suture using HWES on day 7. The mean closure time using barbed suture (142.50 ± 34.803 secs) was significantly (p = 0.001) shorter than that with non-barbed suture (204.56 ± 52.94 secs). The mean VAS for the barbed suture (0.97 ± 1.89) was less (p = 0.015, 95% CI) than the non-barbed suture (2.50 ± 2.91) on day 3. The suture handling ease was comparable between the two groups. Conclusion: Monofilament unidirectional PGCL barbed suture has merits over the non-barbed suture with regards to superior post-operative incision healing, reduced incision closure time (43%), lower post-operative pain and comparable ease of suture handling. Hence, knotless PGCL suture is a promising alternative for intra-oral surgical incision closure in oral and maxillofacial surgery. [ABSTRACT FROM AUTHOR]

OBJECTIVE To describe the repair utilizing integral-anchor barbed suture in equine rectal tears. ANIMALS 3 horses aged 3 to 10 years old with grade 3 to 4 rectal tears. CLINICAL PRESENTATION Grade 3 and 4 rectal tears were referred for surgical repair immediately after iatrogenic tearing or tearing during parturition. Integral-anchor barbed suture (Stratafix Symmetric PDS Plus, size 1, 18" CT-1) was placed using longhandled instruments or hand closuredepending ontheaccessibilityand visibility of thetear. Closureof grade 3 tears was performed using a continuous appositional pattern. A horizontal mattress pattern was performed in the grade 4 tear. No other surgical procedures were performed. RESULTS Two grade 3 tears were successfully repaired with no complications and discharged from the hospital. One grade 4 tear was successfully repaired; however, 4 days post-surgery partial dehiscence of the suture site occurred, and the horse was euthanized. CLINICAL RELEVANCE Grade 3 rectal tears were repaired successfully by using an integral-anchor barbed suture. No post-operative complications were reported. Blind hand suturing could be performed in cranial locations when the laceration could not be made visible. For grade 4 rectal tears, additional surgical procedures beyond barbed suture closure are needed. [ABSTRACT FROM AUTHOR]

Background: Congenital diaphragmatic hernia (CDH) repair can be challenging, particularly when a larger defect is present. Barbed sutures prevent the suture from slipping back after approximation of the tissues. Although introduced almost 2 decades ago, barbed sutures have not been widely used for CDH repair. We report our initial experience and pitfalls. Methods: All patients presenting with CDH from 2021 onward underwent repair using barbed sutures. Demographics, operative parameters, complications, and outcomes were prospectively recorded. Results: A total of 13 patients underwent CDH repair during the study interval (median age 6 days, range 3 days to 5.75 years). Median operative time was 89 min (range 46 to 288 min). Five thoracoscopic and eight open procedures were performed. Severe pulmonary hypertension and ECMO (extracorporeal membrane oxygenation) were considered contraindications for thoracoscopic repair. The included patients were compared to a historic controlled group performed without barbed sutures. The barbed suture facilitated easy and quick closure of the defects in most cases and obviated the need for knot tying. One patient in the thoracoscopic group had a patch placed due to high tension after the barbed sutures tore the diaphragm. At a median follow-up time of 15 months (range 2 to 34 months), one patient had died, and one patient with complete diaphragmatic agenesis was home-ventilated. There were no recurrences. Median operative time trended lower (89 min) than in the historic control group repaired without barbed sutures (119 min, p < 0.06) after eliminating outliers with large, complex patch repairs. Conclusions: Barbed sutures simplify congenital diaphragmatic hernia repair regardless of whether a minimal-invasive or open approach is performed. Patch repair is not a contraindication for using barbed sutures. The resulting potential time savings make them particularly useful in patients with cardiac or other severe co-morbidities in which shorter operative times are essential. In cases with high tension, though, the barbs may tear through and produce a "saw" effect on the tissue with subsequent damage. [ABSTRACT FROM AUTHOR]

The primary objective of this study was to compare time efficiency and complication rates between smooth monofilament suture (SMS) and barbed suture (BS) using the three-layer continuous incisional closure pattern after ovariohysterectomy in a high-quality high-volume spay/neuter clinic. The study was designed as a randomized controlled trial enrolling 71 adult female dogs. Dogs were randomly assigned to SMS or BS treatments. The effect of closure with BS or SMS on closure time was tested through multilevel, multivariable linear regression in a generalized linear mixed model. Body condition score, weight, and pre-closure incision length were tested as covariates. Surgeon was included in the model as a random effect. Pre-closure incision length (p = 0.01) and method (p ≤ 0.0001) were associated with closure time. Adjusting for pre-closure incision length, the average time for closure with SMS was 6.5 min (range 3.70–10.31 min), and the average time for closure with BS was 4.91 min (range 3.05–8.05 min). Accounting for the closure method, the closure time increased by 39 s for each additional centimeter of incision length. BS was more efficient than SMS when performing the three-layer continuous suture pattern. No short-term telemedicine-assessed complications were noted with either treatment method. BS can improve efficiency in surgical closures, especially considering large volumes of animals, and appears to have a similar short-term, telemedicine-assessed complication rate when compared to SMS.

Background: Wound closure in joint replacement surgeries is crucial for postoperative rehabilitation. Despite substantial advances in total knee arthroplasty (TKA), no guidelines/recommendation or consensus practice statement available internationally or nationally around the optimal method of wound closure. The study aimed to develop evidence-based consensus on current practices, and proposed adoption of advanced wound closure initiatives. Methods: From Nov 2020 to Jan 2021, a group of 12 leading orthopedic surgeons from India met virtually under the Success in Total joint replacement through Recommendation In wounD closure (STRIDE) initiative. Expert committee used Delphi method to evaluate definitional statements that were identified through a comprehensive review of the published literature. Over three rounds of iterative voting, revision, and exclusion, the expert panel provided recommendations based on their clinical expertise and scientific evidence. Statements that reached ≥ 80% agreement was considered as "consensus". A survey poll was conducted following each round to add or suggest changes to the statements. Results: General recommendations include marking the arthrotomy before incision, placing the knee in flexion (less than 90°) for re-approximation during arthrotomy closure. The barbed suture can be a good alternative to traditional sutures for providing water-tight capsule closure and topical skin adhesives (TSAs) to staples for minimizing hospital visits and improving patient satisfaction. Conclusion: This consensus provides interim guidance and practical references to orthopedic surgeons of India enabling easy access to evidence-based healthcare solutions for TKA wound closure. These recommendations need to be periodically reviewed in light of emerging evidence. [ABSTRACT FROM AUTHOR]

The barbed suture, which can eliminate knot tying and accelerate the placement of sutures, is an innovative type of suture, whereas the benefits of cosmetic surgeries (CS) are controversial. This study aimed to comprehensively evaluate the effectiveness and safety of barbed sutures in CS. PubMed, EMBASE, Cochrane Library, and ClinicalTrials.gov were searched for English studies comparing the use of barbed with conventional sutures in CS up to October 2020. The updated Cochrane risk-of-bias tool (ROB2.0) and Newcastle-Ottawa Scale (NOS) were utilized to evaluate the risk of bias. Subgroup analysis was performed according to study designs and barbed suture types. A total of 14 studies, including 5 randomized controlled trials and 9 cohort studies, were included (risk of bias: moderate to low), representing 2259 patients. The barbed suture was identified to reduce suture time (mean difference [MD]=−6.18, 95% confidence interval [CI]: −8.75 to −3.60, P < 0.00001) and operative time (MD=−10.80, 95% CI: −20.83 to −0.76, P = 0.03) without increasing the hospital stays and total postoperative complications (most were Clavien I and IIIa). No significant difference was detected for incisional infection, delayed wound healing, and hematoma; however, increasing incidence of wound dehiscence (odds ratio [OR]=1.60, 95% CI: 1.09–2.34, P = 0.02) and suture extrusion (OR=3.97, 95%CI: 1.96–8.04, P = 0.0001) were found, particularly in the unidirectional barbed suture subgroup. Barbed sutures might also help CS advance and reduce seroma formation. The barbed suture was effective in CS; however, its safety needs to be cautiously interpreted as it might be related to more wound dehiscence and suture extrusion despite similar total postoperative complications with conventional sutures. This study might provide important references for decision-makers and clinicians, though further evidence of randomized design, larger sample size, longer follow-up, and standardized rating approaches are warranted.

A barbed suture has been demonstrated to be effective in shortening the stitching time and improving the aesthetic appearance of the stitches during the entire knee replacement. However, no meta‐analyses have been conducted specifically to evaluate the effect of the barbed thread on wound complications relative to the conventional suture. A comprehensive search of the PubMed database, the Embase database, the Cochrane Library and the Web of Science was performed to obtain search data up to June 2023, and only randomised controlled trials were included in this meta‐analysis. We used Review Manager 5.3 for data synthesis and analysis. This meta‐analysis included eight studies. It was found that the use of barbed sutures did not improve the incidence of the disease, the infection of the wound, the closure of the abscess and the injury. However, because of the limited sample size of the randomised controlled trials for this meta‐analysis, the data should be handled with caution. More high‐quality, large‐sample studies will be required to confirm the results. [ABSTRACT FROM AUTHOR]

Purpose: Barbed suture provides a rapid and effective method for closure in minimally invasive surgery. However, postoperative complications involving barbed suture have been reported in recent years. The aim of this study is to introduce a novel hidden stitching technique for peritoneal closure in laparoscopic hernia repair. Method: This study retrospectively analyzed the data of patients with laparoscopic transabdominal preperitoneal patch (TAPP). In the hidden stitch (HS) group, the barbed suture was hidden on the dorsal side of the peritoneum and two stitches were returned in the opposite direction after the suture reached the end point. In the non-hidden stitch (NHS) group, the barbed sutured was exposed in the peritoneal cavity with a tail stump of approximately 10 mm preserved to prevent the peritoneal sutures from loosening. Results: Twenty-seven patients in the HS group were compared with 53 in the NHS group. There were no differences in age, body mass index, surgical bleeding, or length of hospital stay between the two groups. The peritoneal defect closure time was slightly longer (3 min) in the HS group, but the overall operation time was not significantly extended. There were 8 cases of postoperative complications (P =.035) including 4 cases of bowel obstruction due to the tail of the barbed thread penetrating the small intestine mesenteric and two cases of seroma. There were no postoperative complications in the HS group. Conclusions: The hidden stitch method is a safe and feasible peritoneal closure technique that may reduce postoperative complications caused by barbed suture in laparoscopic hernia repair.

Abstract Introduction Peptic ulcers are caused by unbalanced acid production, and proton pump inhibitors (PPIs) in recent decades have helped to treat peptic ulcers effectively. Meanwhile, the incidence of perforated peptic ulcer (PPU) persists and has a high mortality rate if there is no adequate management. Primary closure with a modified Graham’s patch was well performed in early detected PPU with a small size

Inguinal hernias (IHs) and ruptures are a relatively common condition in horses, occurring in foals (congenital) and adult (acquired) animals. A retrospective observational analysis was conducted on 40 cases that underwent laparoscopic surgery to close the VRs using barbed sutures alone or combined with other techniques. Signalment, clinical presentation, surgery, and follow-up data were obtained. In total, fifty-nine VRs were closed using barbed sutures (alone or in combination with other methods), with six cases performed prophylactically and forty-four due to acquired IH. Of the forty-four cases with IH, four were non-strangulated hernias, while thirty presented with strangulated small intestines (twenty-eight acquired and two congenital). The results obtained in this study suggest that laparoscopic hernioplasty with barbed sutures is an effective and safe surgical procedure that could be recommended as a standard practice for managing inguinal hernias in horses, particularly when sparing testicles or preserving reproductive capabilities is a priority.

Abstract Background Incisional hernia following abdominal surgery is a frequent complication of midline laparotomy. This complication is strongly associated with the technique and material used for suture. While a monofilament absorbable suture is recommended to prevent incisional hernia, it can lead to suture loosening or surgical-knot breakage. Although barbed sutures can be an alternative suture material in abdominal fascial closure, evidence for its safety and effectiveness is lacking. Therefore, we designed a prospective randomized trial to evaluate the safety and efficacy of absorbable barbed sutures for midline fascia closure in minimally invasive surgery for colorectal and gastric cancers in comparison with conventional absorbable monofilament sutures. Methods A total of 312 patients who underwent minimally invasive surgery for colorectal and gastric cancers will be randomly allocated to either the absorbable barbed or monofilament suture group for abdominal fascia closure in a 1:1 ratio. The primary outcome is incisional hernia rate within 3 years after surgery, as verified by physical examination and computed tomography. Postoperative complications, including surgical site infection, postoperative pain, and quality of life, will be compared between two groups as secondary outcomes. The investigator will examine the patients until discharge and at 6, 12, 18, 24, and 36 months postoperatively. Discussion This is the first randomized controlled trial to compare absorbable barbed sutures with monofilament sutures for midline fascia closure in minimally invasive surgery. If absorbable barbed sutures demonstrate superior results to those of monofilament sutures, this type of suture material may be recommended as an alternative option for abdominal fascia closure.

Introduction: Peptic ulcers are caused by unbalanced acid production, and proton pump inhibitors (PPIs) in recent decades have helped to treat peptic ulcers effectively. Meanwhile, the incidence of perforated peptic ulcer (PPU) persists and has a high mortality rate if there is no adequate management. Primary closure with a modified Graham's patch was well performed in early detected PPU with a small size < 2 cm. A laparoscopic approach for PPU was prescribed for decades with proven feasibility and safety. We introduced an effective technique combined with barbed suture and modified Graham's patch, which can significantly reduce the surgical time without significantly increasing morbidity and mortality compared with traditional interrupted suture. Patients and method: We retrospectively collected data from January 2014 to December 2020 in Keelung Change Gung Memorial Hospital, and a total of 154 patients receiving laparoscopic repair of PPU were included. There were 59 patients in the V-loc group (V group) and 95 patients in the laparoscopic primary repair group (P group). Results: The V group had a significantly shorter operation time than the P group (96.93 ± 22.14 min vs. 123.97 ± 42.14, P < 0.001). Ten patients suffered from morbidity greater than the Clavien‒Dindo classification 4 (5 from V group, and 5 from P group). Three patients with leakage were reported. Two patients were in the V group, and one patient was in the P group (p = 0.432). Conclusion: Laparoscopic repair with barbed suture and modified Graham's patch provides a simple and effective technique in the management of acute abdomen. This technique can be easily performed by experienced surgeons and trainees in minimally invasive surgery without affecting patient safety. [ABSTRACT FROM AUTHOR]

Objective: To compare the ultrasonographic features of uterine scars and clinical symptoms after cesarean delivery (CD) using barbed and conventional smooth sutures. Methods: This case–control study enrolled women who underwent primary CD at 37 weeks of pregnancy or later. The uterus was closed using either double‐layer unidirectional barbed suture or conventional double‐layer smooth suture. Ultrasound scans of the uterine scar and evaluations of menstrual patterns were performed at 6, 12, and 24 months after surgery. Results: In all, 102 patients underwent uterine closure with barbed suture, while 135 patients underwent smooth suture. At 6 months, patients in the barbed group had a lower incidence of uterine niches (20.2% vs 32.6%) that were also shallower in depth (P < 0.001). Lower incidence of niches was also observed in the barbed group at 12 and 24 months (P = 0.043 and 0.048, respectively). At these two follow‐up times, the smooth group had a higher number of patients reporting postmenstrual spotting (P < 0.05) and more postmenstrual spotting days per month (P < 0.050). Conclusion: The use of double‐layer barbed suture during CD was associated with a lower incidence of scar niches and a more favorable menstrual pattern compared with the use of smooth suture. Synopsis: Compared to conventional smooth suture, double‐layer barbed suture during cesarean 26 delivery results in a lower incidence of scar niches and an improved bleeding pattern.

Background: In recent years, the thread‐lifting technique has become widely used in clinical settings. Several thread products are used in clinical practice, and there are many differences between products in terms of many aspects. Methods: Six commercial thread products were collected and evaluated. The general structure, microstructure, elastic modulus, and strength were evaluated using microscopies and tensile testing in vitro. Seventy‐two female rats were divided into six groups. Tissue samples were harvested and histologically evaluated at 1st, 4th, 8th, and 12th week using hematoxylin and eosin and Masson's trichrome staining. Results: There were differences between products in terms of barb shape, microstructure, elasticity, and strength, and that could be attributed to the materials and barb structures. All threads showed good biological safety, and the density of collagen area in the dermis was increased compared to that in the control group. Conclusions: This study provided an objective evaluation of barbed thread products, which indicated that all products can be used safely with certain effects in different indications.

Objective: To compare the effects of barbed suture (BS) and conventional suture (CS) on perioperative conditions and ovarian function in the excision of ovarian mature cystic teratoma (MCT) by laparo‐endoscopic single‐site surgery (LESS). Methods: The present study is an ambispective cohort study conducted in an affiliated tertiary hospital between May 2019 and October 2020. Women treated by LESS cystectomy for unilateral ovarian MCT were included. BS or CS were applied in the surgery. Results: BS and CS groups were matched 1:1 for age, body mass index and ovarian cyst volume (40 women per group). There were no significant differences in baseline characteristics. Mean operating time (53.89 ± 14.80 versuss 67.93 ± 19.23 min, P = 0.004) and suturing time (11.85 ± 6.68 versus 19.76 ± 12.75 min, P = 0.006) were significantly shorter in the BS group than the CS group. No significant differences were found in serum anti‐Müllerian hormone (AMH) levels between groups at baseline, postoperative day 1, 3 months, and 12 months. However, serum AMH was significantly lower than baseline at postoperative day 1, 3 months, and 12 months in both groups. Conclusion: BS provides shorter operating and suturing time than CS, without increasing damage to ovarian function in LESS cystectomy for ovarian MCT. Synopsis: Barbed suture is recommended to close the ovarian cortex in cystectomy for ovarian mature cystic teratoma by laparo‐endoscopic single‐site surgery. [ABSTRACT FROM AUTHOR]

Fixation of the cartilaginous vault is an important maneuver in preservation rhinoplasty to reduce hump recurrences. This paper presents a cartilaginous vault fixation technique with a barbed suture. Forty-six patients who underwent closed-approach high-septal-resection dorsal preservation rhinoplasty between August 2019 and March 2020 were included in this retrospective study. According to the cartilaginous vault fixation sutures applied, the patients were divided into two main groups as follows: (1) barbed suture and (2) conventional suture. Standardized postoperative 1-month lateral view photographs were scanned for the presence of any degree of hump recurrence. The Rhinoplasty Outcome Evaluation (ROE) scale was applied at 12 months. Hump recurrence was detected in one patient in the barbed suture group (n = 21) and one patient in the conventional suture group (n = 25; p > 0.05). For the ROE scores and number of satisfied patients, no statistically significant difference was found between the barbed and conventional suture fixation techniques (p > 0.05). Fixation with barbed suture showed similar results to conventional suture fixation. Barbed sutures can be used for cartilaginous vault fixation, taking advantage of the ease of placement in closed rhinoplasty. This study reflects level of evidence IV. [ABSTRACT FROM AUTHOR]

Background: Un-knotted barbed suture constructs are postulated to decrease repair bulk and improve tension loading along the entire repair site resulting in beneficial biomechanical repair properties. Applying this repair technique to tendons has shown good results in ex-vivo experiments previously but thus far no in-vivo study could confirm these. Therefore, this current study was conducted to assess the value of un-knotted barbed suture repairs in the primary repair of flexor tendons in an in-vivo setting. Methods: Two groups of 10 turkeys (Meleagris gallapovos) were used. All turkeys underwent surgical zone II flexor tendon laceration repairs. In group one, tendons were repaired using a traditional four-strand cross-locked cruciate (Adelaide) repair, while in group two, a four-strand knotless barbed suture 3D repair was used. Postoperatively repaired digits were casted in functional position, and animals were left free to mobilise and full weight bear, resembling a high-tension post-op rehabilitation protocol. Surgeries and rehabilitations went uneventful and no major complications were noted. The turkeys were monitored for 6 weeks before the repairs were re-examined and assessed against several outcomes, such as failure rate, repair bulk, range of motion, adhesion formation and biomechanical stability. Results: In this high-tension in-vivo tendon repair experiment, traditionally repaired tendons performed significantly better when comparing absolute failure rates and repair stability after 6 weeks. Nevertheless, the knotless barbed suture repairs that remained intact demonstrated benefits in all other outcome measures, including repair bulk, range of motion, adhesion formation and operating time. Conclusions: Previously demonstrated ex-vivo benefits of flexor tendon repairs with resorbable barbed sutures may not be applicable in an in-vivo setting due to significant difference in repair stability and failure rates. Level of Evidence: Level IV (Therapeutic) [ABSTRACT FROM AUTHOR]

Introduction: Posterior cervical spine approaches have been associated with increased rates of wound complications compared to anterior approaches. While barbed suture wound closure for lumbar spine surgery has been shown to be safe and efficacious, there is no literature regarding its use in posterior cervical spine surgery. In a cohort of patients undergoing elective posterior cervical spine surgery, we sought to compare postoperative complication rates between barbed and traditional interrupted suture closure. Methods: A retrospective review of demographics, past medical history, and operative and postoperative variables collected from a prospective registry between July 1, 2016, and June 30, 2020 was undertaken. All patients 18 years old and above undergoing elective posterior cervical fusion were included. The primary outcome of interest was wound complications, including surgical site infection (SSI), dehiscence, or hematoma. In addition, numerical rating scale (NRS) neck pain (NP), NRS arm pain (AP), Neck Disability Index (NDI), and operative time were collected. A variety of statistical tests were used to compare the two suture groups. Results: Of 117 patients undergoing posterior cervical fusion, 89 (76%) were closed with interrupted suture and 28 (24%) with barbed suture. The interrupted cohort were more likely to have >1 comorbidity (p

Abstract Background Anastomotic leakage (AL) is one of most severe postoperative complications following low anterior resection (LAR) for rectal cancer, and has an adverse impact on postoperative recovery. The occurence of AL is associated with several factors, while few studies explored the role of intracorporeal barbed suture reinforcement in it. Methods Consecutive cases underwent laparoscopic LAR for rectal cancer from Mar. 2018 to Feb. 2021 in our center were retrospectively collected. Cases were classified into the intracorporeal barbed suture reinforcement group and the control group according to whether performing intracorporeal reinforcement with barbed suture, and AL incidences were compared between two groups. Propensity score matching (PSM) was then performed based on identified risk factors to reduce biases from covariates between two groups. AL incidences in the matched cohort were compared. Results A total of 292 cases entered into the study, and AL incidences were significantly lower in the intracorporeal barbed suture reinforcement group compared with the control group (10.00% vs 2.82%, P = 0.024). Sex, BMI, preoperative adjuvant chemoradiotherapy and anastomotic level were chose for PSM analyses based on previous studies. In the matched cohort, the AL incidences were still significantly lower in the intracorporeal barbed suture reinforcement group (10.57% vs 2.44%, SD = 0.334). Conclusions Intracorporeal barbed suture reinforcement is associated with low AL incidences after laparoscopic LAR for rectal cancer, which is a potential procedure for reducing AL and worthy of application clinically.

The enrolled patients were divided into two groups according to the suture mode, with 45 cases (group A) receiving closure of the deep tissue with a barbed suture and intradermal suture of the incision with another barbed suture and 49 cases (group B) receiving closure of the deep tissue with absorbable suture and interrupted suture of the incision with nonabsorbable suture. Further comparisons were performed regarding incision length, suture time, postoperative incision complications, Hollander Wound Evaluation Score (HWES), Hospital for Special Surgery (HSS) knee score, American Knee Society (AKS) score, and Patient and Observer Scar Assessment Scale (POSAS). The clinical effects of the two suture modes in TKA and the patients’ aesthetic satisfaction with the incision were also evaluated at 2 weeks, 3 months and 6 months after the operation.Results: Compared with group B, group A had higher HWES at 2 weeks after the operation (P < 0.05), shorter suture times (P < 0.05) and lower POSAS scores at 3 and 6 months after the operation (P < 0.05). However, no significant difference was observed between the two groups in incision length, complication rate, HSS or AKS scores (P > 0.05).Conclusion: Compared with the interrupted suture, the use of whole-layer barbed suture for incision closure after TKA has the advantages of a safe and effective outcome, short operation time, high cosmesis degree of the wound scar and high patient satisfaction.Keywords: barbed suture, knee arthroplasty, interrupted suture, aesthetic satisfaction of incision

Background: Congenital diaphragmatic hernia (CDH) repair can be challenging, particularly when a larger defect is present. Barbed sutures prevent the suture from slipping back after approximation of the tissues. Although introduced almost 2 decades ago, barbed sutures have not been widely used for CDH repair. We report our initial experience and pitfalls. Methods: All patients presenting with CDH from 2021 onward underwent repair using barbed sutures. Demographics, operative parameters, complications, and outcomes were prospectively recorded. Results: A total of 13 patients underwent CDH repair during the study interval (median age 6 days, range 3 days to 5.75 years). Median operative time was 89 min (range 46 to 288 min). Five thoracoscopic and eight open procedures were performed. Severe pulmonary hypertension and ECMO (extracorporeal membrane oxygenation) were considered contraindications for thoracoscopic repair. The included patients were compared to a historic controlled group performed without barbed sutures. The barbed suture facilitated easy and quick closure of the defects in most cases and obviated the need for knot tying. One patient in the thoracoscopic group had a patch placed due to high tension after the barbed sutures tore the diaphragm. At a median follow-up time of 15 months (range 2 to 34 months), one patient had died, and one patient with complete diaphragmatic agenesis was home-ventilated. There were no recurrences. Median operative time trended lower (89 min) than in the historic control group repaired without barbed sutures (119 min, p < 0.06) after eliminating outliers with large, complex patch repairs. Conclusions: Barbed sutures simplify congenital diaphragmatic hernia repair regardless of whether a minimal-invasive or open approach is performed. Patch repair is not a contraindication for using barbed sutures. The resulting potential time savings make them particularly useful in patients with cardiac or other severe co-morbidities in which shorter operative times are essential. In cases with high tension, though, the barbs may tear through and produce a “saw” effect on the tissue with subsequent damage.
