Reproductive outcome after laparoscopic ovarian cystectomy using barbed sutures versus conventional smooth sutures: Aretrospective cohort study.

To investigate the effects of barbed and conventional sutures on reproductive outcomes and ovarian reserve after laparoscopic treatment for benign non-endometrioma ovarian cysts. 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. 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). 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.

Clinical outcomes of triclosan-coated barbed suture in open hernia repair: a retrospective cohort study

PurposeWe assessed clinical outcomes of patients undergoing open hernia repair using STRATAFIX™ Symmetric, a barbed triclosan-coated suture (TCS; Ethicon), versus conventional polydioxanone suture (PDS) for abdominal wall closure.MethodsThis single-center retrospective cohort study identified patients undergoing hernia repair. The site used PDS from 2013 to 2016 and switched exclusively to barbed TCS in 2017. Outcomes were assessed at 30, 60, and 90 days. Multivariate regression analyses and Cox proportional hazards models were used.ResultsOf 821 hernia repairs, 446 used barbed TCS and 375 used conventional PDS. Surgical site infections (SSIs) were significantly less frequent with barbed TCS (60 days, 5.9% vs. 11.4%; P = 0.0083; 90 days, 5.9% vs. 11.7%; P = 0.006) and this remained consistent after multivariate adjustment (60 days, OR [95% CI]: 0.5 [0.3–0.9]; 90 days, 0.5 [0.3–0.9]). Among patients with SSI, deep SSIs were less frequent with barbed TCS (60 days, 9.1% vs. 35.7%; P = 0.022; 90 days, 9.1% vs. 34.9%; P = 0.0252). Barbed TCS significantly reduced the risk of perioperative complications (HR [95% CI]: 0.5[0.3–0.8]; P = 0.0058). Hospital length of stay was 2.5 days shorter with barbed TCS (mean [95% CI]: 5.7[4.9–6.6] vs. 8.2[7.3–9.1] days; P < 0.0001). No differences in reoperation rate over time were observed by type of suture (HR[95% CI]:1.3 [0.5–3.4]; P = 0.4793).ConclusionsThis study showed that patients who underwent open hernia repair appeared to recover equally well regardless of the suture type. In addition, the use of barbed TCS was associated with significantly reduced risk of perioperative complications and hospital length of stay.

Outcomes of Purse-string versus Conventional Linear Suture Closure of the Skin Wound following Ileostomy Reversal

Background: Intestinal stomas are made in a variety of settings and their reversal is also a routine surgery. Due to their clean, contaminated nature, there is a high risk of surgical site infection post-operatively. The objective of this study is to determine the difference in outcomes in two different techniques of skin closure after stoma reversal&#x0D; Methods: The study was conducted at department of general surgery, Pakistan Institute of Medical Sciences, Islamabad, over a period of six months. Seventy-one patients who underwent ileostomy reversal surgery in an elective setting were assigned two groups randomly: 34 in Group A and 37 in Group B. The group A patients underwent purse string closure for stoma site skin wound, whereas patients in group B underwent conventional linear closure. Time taken for surgery was noted and the patients were followed over one month period for development of any surgical site infection or dog-ear deformity.&#x0D; Results: The incidence of surgical site infection was 8.8% in the purse string closure group compared to 43.2 % in the linear closure group. Seven patients in group B developed dog ear deformities, whereas no such case was noted in Group A.&#x0D; Conclusions: Purse string closure is an effective and applicable technique for the closure of skin wounds after stoma reversal surgery. It is comparatively better in terms of prevention of surgical site infection as well as dog ear deformity in the closure of skin wounds after ileostomy reversal.

Comparative Evaluation of Autologous Fibrin Glue and Conventional Sutures in the Treatment of Gingival Recession Using Connective Tissue Graft - A Randomised Controlled Clinical Trial.

The combination of the coronally positioned flap with connective tissue grafting in treating gingival recession defects has been shown to demonstrate the highest success rate. The aim of the present study was to compare and evaluate the efficiency between autologous fibrin glue (AFG) and conventional absorbable sutures in the treatment of marginal tissue recessions using connective tissue grafts (CTGs) and the coronally advanced flap (CAF) technique. Twenty Miller's class I and II recession sites in maxillary or mandibular areas in chronic periodontitis patients were treated as group I (test): CTG + CAF + AFG; and group II (control): CTG + CAF with conventional absorbable sutures. Clinical parameters in both groups were recorded at baseline (t0) and six months (t1) postoperatively in terms of gingival recession height (RH), root coverage esthetic score (RCES), visual analogue scale (VAS), and healing index (HI). The RH, RCES, VAS, and HI were significantly reduced at the end of six months compared to baseline ( P < 0.005) in both groups; however, there was no statistical difference between the groups, indicating the equivalent efficacy of AFG and conventional sutures in healing. All the treated sites were found to have appreciable root coverage with satisfactory post-operative healing. Hence, it may be suggested that both AFG and absorbable sutures are equally efficient in post-surgical soft tissue healing.

BackgroundPterygium is a common ocular surface disorder that requires surgical intervention for treatment. Conjunctival autografts are preferred over simple excision due to lower recurrence rates. This systematic review and meta-analysis...

Evaluation of two liver biopsy and rectal sealing techniques in dog cadavers undergoing Natural Orifices Transluminal Endoscopic Surgery (NOTES) by transrectal access

The aim of this study was to evaluate two liver biopsy techniques by transrectal Natural Orifice Transluminal Endoscopic Surgery (NOTES) and compare tensiometric parameters of rectal sealing using 2-octyl cyanoacrylate glue or conventional rectal sutures in a dog cadaver model. In sixteen dog cadavers two liver biopsy techniques were performed via transrectal NOTES using either polypectomy diathermy forceps or endoscopic oval biopsy forceps. The cadavers were divided into two groups: Glue Group (GG) where rectal sealing was performed with 2-octyl cyanoacrylate glue and Suture Group (SG) with the rectal defect sealed with simple continuous extracorporeal 3-0 polydioxanone sutures. The rupture pressure of the seals was measured on a rectal burst test. The diathermy polypectomy endoscopic forceps biopsy technique was significantly faster (p&lt;0.001) and provided larger diameter samples. Rectal sealing was significantly faster (p&lt;0.001) in the GG. There was no difference between the two groups with regard to rupture pressure (258.5 mmHg) with air insufflation. Using endoscopic oval biopsy forceps, biopsy samples can only be collected from the surface of the liver, whereas polypectomy forceps with a diathermy loop can be used to collect samples from the tip of the hepatic lobe. There was no difference in rectal rupture pressure in the burst test between the cadavers where sealing was performed with rectal sutures and those where cyanoacrylate adhesive was used.

Comparison of conjunctival pedicle flap to corneal fixation strength achieved by Tisseel® fibrin glue, ethyl cyanoacrylate adhesive, ReSure® hydrogel sealant, and conventional suturing with 8-0 VICRYL® ophthalmic suture.

To determine and compare the fixation strength of conjunctival pedicle flaps to cornea achieved via conventional ophthalmic suture and three different adhesive compounds. Ex vivo porcine globes. Following a 6 mm wide 500-micron-restricted depth lamellar keratectomy, conjunctival pedicle flaps were secured to the keratectomy site with either 8-0 VICRYL® suture or one of three adhesive products, including Tisseel® bioadhesive, ReSure® synthetic adhesive, or ethyl cyanoacrylate adhesive (n = 10 per surgical group). Adhesive application protocol varied by product based upon adhesive biocompatibility. Corneoconjunctival tissues were then harvested, clamped in a tensile testing device, and loaded at a rate of 1 mm/s under video surveillance until the point of failure. Peak load was determined for each test and used to compare fixation strength between samples. Forty conjunctival flaps were performed, with 6 omitted from evaluation due to dehiscence prior to tensile testing. Of the 34 flaps analyzed, 10 were secured with suture, 10 with cyanoacrylate, 8 with ReSure®, and 6 with Tisseel®. Flaps secured with suture withstood significantly higher applied tensile force compared with cyanoacrylate (p = .02474), ReSure® (p = .00000), and Tisseel® (p = .00002). Flaps secured with cyanoacrylate withstood significantly greater force than those secured with ReSure® and Tisseel® (p = .01194 and 0.01798, respectively). There was no significant difference in fixation strength between ReSure® and Tisseel® glue (p = .95675). Conjunctival pedicle flap fixation using 8-0 VICRYL® suture fixation was able to withstand significantly greater maximum tensile force compared to ReSure®, Tisseel®, or cyanoacrylate adhesives. Fixation strength achieved with cyanoacrylate adhesive was significantly greater than that achieved with ReSure® or Tisseel®.

Efficacy of Octyl-Cyanoacrylate Dermabond Adhesive Glue versus Polyglactin 3/0 Suture for Closure of Caesarean Section Skin Incision - A Prospective Randomised Controlled Trial

This was a prospective randomised controlled trial conducted at a tertiary hospital on 82 women who underwent caesarean section aiming to assess the efficacy of octyl-cyanoacrylate tissue adhesive glue versus polyglactin 3/0 suture for the closure of caesarean sections skin incision. The study group consisted of 41 women who underwent skin closure using octyl-cyanoacrylate tissue adhesive glue, whereas 41 women in the control group had subcuticular skin closure using polyglactin 3/0 sutures. The choice of anaesthesia, prophylactic antibiotic, operative technique, and immediate post-operative oral analgesia was standardised between the two groups. Time taken for skin closure, pain score at day 2 and 14, the total analgesia dose needed and duration (day two onwards), and any adverse events were recorded. The time required for skin closure was significantly less in the study group, with a mean difference of 97.7 seconds (170.8 seconds vs 268.5 seconds, p&lt;0.001). Pain scores on day 2 were similar between the two groups (4.0 vs 5.0, p=0.09), whereas pain score on day 14 was significantly lower in the study group (2.0 vs 4.0, p&lt;0.001). The median duration (day two onward) of oral analgesia use was four days in the study group and six days in the control group. The difference was statistically significant (p=&lt;0.001). The median amount of additional analgesia required was a third less in the tissue adhesive group than in the control group. On day 14, surgical site infection was similar in both groups. In conclusion, octyl-cyanoacrylate tissue adhesive glue may safely close a caesarean section skin incision. It was associated with faster application, lesser pain score, and lesser need for analgesia without additional adverse events compared to the conventional suturing method.

Robot-assisted Microsurgery in Lower Extremity Reconstruction

In recent years, various robotic systems specifically designed for microsurgical tasks have been developed and approved. There is not much evidence for these systems to date. In our study, we examined the use of robot-assisted microsurgery in the reconstruction of the lower extremity. Data was prospectively collected between February and November 2023. The Symani robotic system was used in 42 robot-assisted microsurgical procedures on the lower extremity, and the results were evaluated and documented. The average age of the patients was 57±18 years. A total of 39 free flap reconstructions (95%), one lymphatic surgical procedure (3%) and two nerve transfers (5%) were performed. In total, 46 anastomoses and coaptations were carried out. This included six arterial end-to-end anastomoses (11%), seven arterial end-to-side anastomoses (13%), 36 venous end-to-end anastomoses (65%), two lymphovenous anastomoses (4%), and five epineural coaptations in the context of nerve transfers (9%). Arterial end-to-end anastomoses took an average of 26±12 minutes, and arterial end-to-side anastomoses took 42±21 minutes. The venous anastomoses took an average of 33±12 minutes. Epineural coaptations took an average of 24±13 minutes. In no procedure was there a need for a conversion to conventional hand suturing. There were two arterial thromboses (5%), one of which was successfully revised to save the flap. One total flap loss occurred, but there were no partial flap losses. Using the Symani robotic system for microsurgical reconstruction of the lower extremity, we were able to demonstrate results that are comparable to conventional microsurgery.

Tough Adhesive Puncture Sealing Sutures with Swelling Triggered Bioadhesion for Enhanced Wound Closure

AbstractSurgical sutures are gold‐standard wound closure devices. However, they are unable to form a tight seal with surrounding tissues, raising the risks of body fluid leakage and surgical site infection. Additionally, the use of sutures can result in cracking at suture roots, damage and micro‐trauma to soft tissues due to the slicing and compression of suture fibers after their placement. Bioadhesives capable of mimicking natural biological interfaces are appealing alternatives, but they cannot achieve the same level of strength as conventional surgical sutures. Here, a tough adhesive puncture sealing (TAPS) suture, featuring swelling‐triggered bioadhesion to mend the gap between the suture and the surrounding tissues with a soft yet tough adhesive interface is reported. This unique design principle of TAPS sutures is applicable to diverse soft tissues of various defect sizes and can be controlled by modulating the hydrogel swelling kinetics. The advantages of the TAPS sutures for meniscal tear repair and intestine tissue sealing ex vivo, corroborates their favorable applications in managing mechanically active musculoskeletal and gastrointestinal tissues are demonstrated. The design and performance of the TAPS sutures offer extensive possibilities for redesigning surgical tools and developing next‐generation medical devices for wound management and tissue repair.

Beyond the Needle: A Comparative Evaluation of Silk Sutures and Cyanoacrylate for Periodontal Flap Closure.

Introduction As the incidence of periodontal diseases continues to surge, there is a concurrent elevation in the demand for periodontal treatment. Periodontal surgical therapy is done to control and eliminate disease activity. Conventionally, silk sutures have been considered the gold standard for post-operative flap closure that leads to biofilm accumulation and tissue trauma. Cyanoacrylates are alternate options to avoid the limitations. Objective The objective of the study was to assess clinical outcomes by comparing the healing after periodontal flap surgery when secured with 3-0 braided silk suture versus cyanoacrylate. Methodology Twenty surgical sites from 10 patients with moderate to severe periodontitis were selected and randomly divided into two groups after phase-1 therapy: the test group (isoamyl 2-cyanoacrylate) and the control group (3-0 silk braided suture). Post-operative wound healing, pain assessment using a verbal rating scale (VRS), and analgesic tablets taken were evaluated on the third, fifth, seventh, and 14th days. Statistical analysis was done using the ANOVA test with the post-hoc Bonferroni test. Results There was no statistically significant difference between the VRS and wound healing index at different levels of intervals during intergroup comparison, but the number of analgesics consumed post-operatively was less in the test group as compared to the control group. Conclusion The present study concluded that isoamyl 2-cyanoacrylate can be used as an alternative to conventional silk sutures as it decreases post-operative pain and discomfort.

MICROSURGICAL REIMPLANTATION OUTCOMES FOR COMPLETE AND INCOMPLETE AMPUTATIONS OF DISTAL PHALANGES OF FINGERS.

The intricate endeavor of replanting the distal phalanx of the finger remains a persistent challenge. In the pursuit of addressing this concern, microsurgical replantation procedures have been systematically examined for distal phalanx injuries encircling the distal interphalangeal (DIP) joint, conducted at the Orthopaedic Hospital situated in Ho Chi Minh City. This investigation encompassed a cohort of 31 patients, comprising individuals with 17 instances of complete and 21 instances of incomplete amputations of the distal phalanges. The subjects' ages spanned a range from 3 to 56 years. The study divulged that eight fingers, involving four complete amputations and four incomplete amputations, did not achieve successful outcomes. In contrast, the remaining 30 fingers exhibited survival. A meticulous long-term follow-up of 17 fingers, extending over a period exceeding six months, unveiled commendable achievements encompassing satisfactory sensory recovery, cosmetic enhancement, and the resumption of pre-injury occupational activities by the patients. Vein anastomosis was revealed as a notably challenging aspect of the surgical procedures. In scenarios where conventional vein suturing was rendered unfeasible, the innovative recourse of one-way drainage emerged as a viable alternative. The endeavor to replant the distal phalanx of the finger engenders a substantial level of complexity, particularly in the realm of venous anastomosis. This research underscores the need for focused efforts to address and surmount the intricacies associated with this aspect of surgical intervention.

Assessing the application of barbed sutures in comparison to conventional sutures for surgical applications: a global systematic review and meta-analysis of preclinical animal studies.

Following an initiative published by Lancet in 2002 and an IDEAL-D framework, the value of preclinical animal studies has garnered increasing attention in recent research. Numerous preclinical animal experiments tried to generate evidence to guide the development of barbed sutures. However, discernible drawbacks and incongruities in outcomes have emerged between clinical and preclinical animal studies. Therefore, this meta-analysis aimed to review the preclinical animal experiments comparing barbed sutures with conventional sutures. The authors hope to facilitate clinical translation of barbed sutures by evaluating effectiveness, safety, and physical properties/reliability. A systematic search of PubMed, EMBASE, Cochrane Library, and ClinicalTrials.gov was conducted to identify controlled preclinical animal experiments comparing barbed sutures with conventional sutures. The risk of bias was assessed using SYRCLE. GRADE approach was used to evaluate evidence quality. Revman was applied to analyze all the data. Subgroup, sensitivity, and meta-regression analyses were also performed. A total of 62 articles were eligible with low to moderate quality, including 2158 samples from 10 different animal species across 27 surgical procedures. Barbed suture exhibited a significant reduction in suture time, limited change in Cross-Sectional Area (CSA), and decreased instances of tissue disruption (all P <0.05). Subgroup analyses, considering both clinical and research significance, indicated that barbed sutures might cause more specific adverse events and demonstrate suboptimal performance of physical properties/reliability. Meta-regression suggested that heterogeneity resulted from variations in studies and animal models. Although barbed suture demonstrated superiority in numerous surgeries for time efficiency, its safety and physical properties/reliability might be influenced by diverse preclinical models, sutures' brand, surgeries, and anatomical sites. Further evaluation, based on standardized and well-designed animal experiments, is essential for medical device development and applications in human beings.

Cyanoacrylate vs. sutures in clean and clean-contaminated surgical wounds - a randomised control study.

Various techniques of closure of surgical incisions have been described ranging from various suture materials, staples and tapes to adhesive compounds. Cyanoacrylate is an adhesive compound available for surgical incision closure. Although sutures have been the preferred universal choice for surgical incision closure, glue is gaining popularity in specific places like pediatric injuries, facial injuries, laparoscopic incision closure, etc. This study aimed to compare the results between the application of cyanoacrylate and conventional suturing. In this randomized control study, patients were divided into two groups of 100 each. The surgical incisions were closed using cyanoacrylate glue in Group A patients and polyamide (EthilonTM 2-0) in Group B patients. Post-operative pain was assessed using Visual Analogue Scale on the first, third, and seventh day. The wounds were evaluated for complications on post-op days 1, 3, 7, and 30 using the ASEPSIS score. Cosmetic outcome was assessed at the end of first month using the Modified Hollander Cosmesis Scale. Post-operative pain was significantly less in the glue group on days 1, 3, and 7. Wound infection with dehiscence occurred in 4 cases (4 %) in Group A and one patient (1 %) in Group B, which was statistically insignificant. There was no significant difference in cosmetic outcomes in either Group. Cyanoacrylate is a good alternative to sutures in skin closure of clean and clean-contaminated surgical wounds.

Comparative analysis of wound healing techniques in postoperative bladder cancer patients.

Bladder cancer is a highly prevalent malignancy that presents significant difficulties in the management of wounds following surgery. The present study investigated the critical necessity to optimize wound healing techniques in patients undergoing bladder cancer surgery by contrasting conventional approaches with advanced modalities in order to promote recovery and mitigate complications. The study assessed the efficacy of conventional and advanced wound healing methods in these patients, taking into account the complex interaction of patient-specific factors and surgical complexities. A cross-sectional analysis was performed on 120 patients who underwent bladder cancer surgery at the first affiliated hospital of Wenzhou Medical University. In addition to medical record evaluations and direct wound assessments, patient interviews were utilized to gather information regarding demographics, surgical specifics, wound healing methodologies and postoperative results. Survival analysis and logistic regression were utilized in statistical analysis, with potential confounding variables such as age, comorbidities and type of surgery being accounted for. Advanced wound healing techniques, such as negative pressure wound therapy, tissue-engineered products, bioactive dressings and platelet-rich plasma (PRP), exhibited distinct advantage in comparison with conventional suturing. The aforementioned techniques, especially PRP, resulted in expedited wound healing, decreased rates of complications (p < 0.05) and enhanced secondary outcomes, including curtailed hospital stays and decreased rates of readmissions. PRP therapy, in particular, demonstrated significant improvements with the faster mean time to wound healing of 9 ± 2 days and lower complication incidence of 2 (6.7%) (p < 0.05), indicating its superior efficacy. A subgroup analysis revealed that younger patients, males and those undergoing laparoscopic surgery exhibited superior outcomes (p < 0.05). The results were further supported by logistic regression and Cox proportional hazards models, which further indicated that sophisticated techniques, notably PRP therapy with a hazard ratio of 3.00 (2.00-4.50) and adjusted odds ratio of 0.20 (0.09-0.43), were effective in improving postoperative recovery. The research clarified the significant advantages that advanced wound healing techniques offered in postoperative care of patients diagnosed with bladder cancer. By customizing these methods to suit the unique requirements of individual patients and specific circumstances of surgical procedures, they can significantly enhance the recuperation process after surgery and set a new standard for patient care.

Gold nanobipyramids-based laser-activated sealants for effective skin sealing and repair

Anisotropic gold nanostructures have gained increased attention for biomedical applications because of their remarkable optical properties. An emerging type of gold nanostructure—gold nanobipyramids (AuNBP)—has been shown to exhibit superior absorption properties compared to conventionally used gold nanoparticles, which makes them attractive for photothermal applications. We generated a high-shape-purity dispersion of AuNBP using a seed-mediated method and embedded them as photothermal conversion agents in a silk fibroin matrix to investigate their efficacy in photothermal sealing of incisional wounds in immunocompetent mice. These AuNBP-doped laser-activated sealants, or AuNBP-LASE were able to absorb near-infrared laser energy and convert it to heat, thereby inducing transient hyperthermia in the wound and the surrounding tissue. This photothermal conversion facilitated rapid sealing of the skin tissue by the AuNBP-LASE, which resulted in faster functional recovery of skin barrier function compared to nylon sutures at the early stages of repair. Further, the biomechanical properties of the healing skin closed with AuNBP-LASE those of intact skin more rapidly compared to incisions approximated with sutures. Histology studies indicated higher penetration of the LASE within the volume of the incision in skin tissue, lower scab formation, and a similar epidermal gap compared to conventional suturing. These results demonstrate that AuNBP-LASEs can be effective as wound approximation devices for photothermal sealing.

Comparative Evaluation of the Aesthetic Outcomes of Octyl-2-Cyanoacrylate Skin Adhesive and Ethilon Suture in Maxillofacial Surgery - A Randomised Clinical Study.

Wound closure methods have evolved, attributed to the armamentarium including the synthetic sutures, staples, surgical adhesive tapes and, most recently, the cyanoacrylate tissue adhesives. Cyanoacrylates have shown promising results in terms of aesthetic outcomes in other fields of surgery. The aim of this study is to compare the aesthetic value of Dermabond over Ethilon suture when used in case of facial surgical incisions. The purpose of this study was to demonstrate the efficacy of Dermabond for wound closure in the head-and-neck region. This study involved 20 subjects undergoing maxillofacial surgery. In 10 subjects, skin closure was done with conventional suturing (Ethilon) and other 10 subjects with tissue glue (2-octyl cyanoacrylate). Observations regarding skin closure time and scar assessment were made, and their results were compared. The mean time for closure in the Dermabond group was 217.2 ± 42.0 s and for Ethilon suture group was 383.3 ± 140.2 s. Dermabond was significantly better than Ethilon sutures at both 1 month and 3 months with P = 0.001 and P < 0.001, respectively. For Dermabond, the average score improved from 8.2 ± 2.5 at 1 month to 6.1 ± 1.6 at the 3rd month. The improvement was statistically significant (P = 0.001) for Ethilon sutures; the average score improved from 12.0 ± 1.2 at 1 month to 10.2 ± 2.0 at 3rd month. The improvement was statistically significant (P = 0.038). Adhesive glue appears to be superior to conventional suturing in clean elective surgeries. It is a safe and effective method of skin closure with less operative time and better cosmesis of the scar.

Comparison of bone tacks and sutures in free gingival graft procedures a clinical study

Objective The aim of the present study was to compare the efficacy of bone tacks and sutures in free gingival graft FGG stabilization during gingival augmentation procedures. Materials and Methods Twelve subjects participated in this study. One site in each subject was randomly assigned into each of the following experimental groups. In the test group, the FGG was stabilized with bone tacks whereas FGG procedure with conventional sutures was performed in the control group. Clinical parameters assessed were the width of keratinized gingiva and plaque index PI scores at baseline 1 month and 3 months. Surface shrinkage SS was recorded at 15 days 1 month and 3 months. Early wound healing score EHS was recorded postoperatively after an interval of 1 week. Results Bone tacks stabilized with FGG were effective in increasing the width of the keratinized gingiva but did not show any added advantage over sutures with no statistical difference between both groups p0.49. In both groups there was similar SS EHS and PI scores with no statistical significance difference between them p1.00. Conclusion This trial was conducted over a period of 3 months and it was observed that bone tacks can be used to stabilize the FGG during mucogingival procedures.

Biomechanical evaluation of the ST-knot: A new suture for flexor tendon repair

PurposeAlthough tendon lacerations are common, there is currently no consensus on choice of suture. Easy and fast sutures that impart enough strength to allow mobilization are needed. This study compared the ex vivo biomechanical strength (force required to create a 2 mm tendon gap) of a novel suture (ST-knot) with that of a conventional suture (double Kessler). Materials and methodsForty fresh deep flexor tendons from porcine forelimbs were used. Both repaired tendon ends were mounted on standard traction jaws of an axial traction machine at an initial distance of 40 mm for all tendons. A high-definition camera was used to determine the force forming a 2 mm gap. Ten tendons in group 1 (ST-knot) and 10 in group 2 (double Kessler) were prepared with PDS 4.0 (single thread for Kessler, double thread for ST-knot). Tendons in groups 3 (ST-knot) and 4 (double Kessler) were repaired with PDS 1.0 using the same principle. ResultsThere was no significant difference in the force required to form a 2 mm tendon gap between groups 1 and 2, and this trend was identical when using a stronger thread in groups 3 and 4. The maximum force before rupture, mode of repair failure, stress and stiffness were also comparable, with no significant differences between groups 1 and 2, or between groups 3 and 4. ConclusionsThe ST-knot showed comparable results to the double-Kessler knot, whichever the thread used. Because it involves fewer steps than conventional techniques and is easy to perform, the ST-knot may offer a therapeutic solution, particularly in complex trauma with multiple tendon injury.

Pain scores and functional outcomes of patients with shoulder labral repair using all-suture anchors versus conventional anchors.

The purpose of this study was to compare PROMs in patients undergoing anterior glenoid labral repair using all-suture versus conventional anchors. We hypothesized PROMs would be similar between groups. We performed a retrospective review of the Arthrex Global Surgical Outcomes System (SOS) database, querying patients who underwent arthroscopic glenoid labral repair between 01/01/2015 and 12/31/2020. Patients aged 18-100, who had isolated glenoid labrum repair with at least 12-month follow-up were included. The visual analog pain scale (VAS), Western Ontario Shoulder Instability Index, Veteran's RAND 12-items health survey, single assessment numeric evaluation and the American Shoulder and Elbow Surgeons score (ASES) were compared preoperatively, 3months, 6months, 1year and 2years postoperatively in patients who received all-suture anchors versus conventional anchors in the setting of anterior glenoid labrum repair. Our primary aim was comparison of PROMs between patients receiving all-suture versus conventional suture anchors. Secondarily, a sub-analysis was performed comparing outcomes based on anchor utilization for patients with noted anterior instability. We evaluated 566 patients, 54 patients receiving all-suture anchors and 512 patients receiving conventional anchors. At two-year follow-up there was no significant difference between the two groups in PROMs. In a sub-analysis of isolated anterior labrum repair, there was an improvement in ASES (P = 0.034) and VAS (P = 0.039) with the all-suture anchor at two-year follow-up. All-suture anchors provide similar or superior pain and functional outcome scores up to 2years postoperatively compared to conventional anchors. As all-suture anchors gain popularity among surgeons, this is the largest scale study to date validating their use in the setting of glenoid labrum repair.
