Background: This experimental comparative study was to evaluate the local effects of three different suture materials on in-testinal anastomosis healing.
Methods: Ethical approval was obtained from the University of Ethical Committee (E-60758568-020-176720). A prospective, experimental comparative analysis was conducted on 24 rats. They were divided into three equal groups; Group 1 underwent colonic anastomosis with Vicryl suture material, Group 2 underwent colonic anastomosis with polypropylene suture; and Group 3 underwent colonic anastomosis with polydioxanone (PDS) suture. The second operation underwent the 7th post-operative day. Adhesion score, anastomotic leakage, anastomotic bursting pressure, hydroxyproline levels, and histopathologic examination were evaluated.
Results: All animals survived, and no leakage, intestinal obstruction, or wound infection was observed during the experiment. The adhesion score was evaluated according to the Diamond classification and same in all groups. Median anastomotic bursting pressure was 125.75 mmHg (10-241) in the Vicryl group, 159.25 mmHg (113-190) in the polypropylene group, and 154.50 mmHg (20-212) in the PDS group. Hydroxyproline tissue concentrations were in the Vicryl group 1699.92±220.8 ng/mg (range: 1509.81-2186.47), in the polypropylene group 1126.24±607.12 ng/mg (range: 53.22-1815.63), and 1547.86±335.2 ng/mg (range: 973.66-1973.2) in PDS group. There was no difference among groups regarding the inflammatory response evaluated by histopathology. There was no statistical significance in all variables evaluated.
Conclusion: This experimental study demonstrates that suture materials did not worsen tissue healing during intestinal anastomosis. Absorbable, slowly-absorbable, and non-absorbable suture materials could be used safely in every situation.

Background/aim: Cesarean section (CS) is a widely performed operation worldwide but data about uterine closure are lacking. We aimed to evaluate scar niches and compare single-layer and double-layer uterine closure at 6 months following CS.
Materials And Methods: This prospective randomized trial assessed 56 women undergoing single- or double-layer uterine closure.

Evaluation of the Efficacy and Accuracy of Super-Flexible Three-Dimensional Heart Models of Congenital Heart Disease Made via Stereolithography Printing and Vacuum Casting: A Multicenter Clinical Trial.

Three-dimensional (3D) printing is an advanced technology for accurately understanding anatomy and supporting the successful surgical management of complex congenital heart disease (CHD). We aimed to evaluate whether our super-flexible 3D heart models could facilitate preoperative decision-making and surgical simulation for complex CHD. The super-flexible heart models were fabricated by stereolithography 3D printing of the internal and external contours of the heart from cardiac computed tomography (CT) data, followed by vacuum casting with a polyurethane material similar in elasticity to a child's heart.

Introduction: Closure of large hernia defects with minimally invasive surgery has long-been a challenge. Barbed sutures have helped us bridge this technical gap, but their off-label use is not well studied.
Materials And Methods: We describe a suturing technique for minimally invasive ventral hernia repair (MIS-VHR) termed "progressive defect tensioning" and explore its theoretical advantages.

Purpose: Displacement minimization of seeds is crucial during surgery in brachytherapy; however, only a few reports have compared the operability of different seeds. TheraStrand-SL is a seed, in which TheraAGX100 is wrapped in polyglactin 910 thread, and intra-prostatic displacement is expected to be reduced compared with that of Thera-AGX100, owing to the complex shape of TheraStrand-SL. We conducted a prospective study on the operability and treatment outcomes of TheraAGX100 and TheraStrand-SL placement by a single operator.
