Biomechanical Features of Bidirectional-barbed Suture: A Randomized Laboratory Analysis

The aim of the current prospective study was to evaluate the biomechanical stability of barbed suture vs. conventional suture. Biomechanical stability of a 14x14-cm PDO/polydioxanone, with a half circle and 36-mm needle, bidirectional barbed 0-Quill suture (Angiotech, Vancouver, British Columbia, Canada) vs. 1-Poliglecaprone 25 (Monocryl, Ethicon, Inc, Somerville, NJ) suture was evaluated on biological specimens. The 1-Monocryl suture was chosen because it is widely used by gynecological surgeons in the repair either of the vaginal cuff or the uterine wall defects. Forty specimens of aponeurotic muscle, obtained from abdominal wall of a lamb, were prepared, and randomly assigned to 1 of 2 repair groups: Group A (n = 20) classic repair with 1-Monocryl suture; Group B (n = 20) 0-Quill barbed suture. Each specimen was transected at the midpoint and then repaired. Biomechanical stability of the repaired specimen was verified on a CMT6000 electromechanical universal testing machine (SANS, MTS SYSTEMS, China Co., Ltd., Shenzhen, China), with a 1kN cell. Biomechanical tests showed that maximum force was similar for 1-Monocryl and 0-Quill respectively (p = non-significant). This randomized laboratory study shows that biomechanical stability of the sutures is comparable

Minilaparoscopic Myomectomy: A Mini-invasive Technical Variant

Objective: We propose a mini-invasive technical variant for laparoscopic myomectomy, which is currently less invasive and more feasible. Study Design: This was a prospective, controlled, randomized trial, involving 170 patients, who underwent laparoscopic myomectomy. Patients were randomized into two groups: Group A (n=98) underwent standard laparoscopic myomectomy, and Group B (n=72) underwent the mini-invasive technique. The current mini-invasive variant is performed with a 10-mm umbilical trocar and only two 5-mm ancillary trocars. Morcellation is transumbilical: a 0 degrees 5-mm optical system is used and is inserted either in the left or in the right iliac trocar according to the surgeon's preference. Results: The degree of surgical difficulty, evaluated using a visual analog scale (VAS), was similar in the two groups (P=nonsignificant). Postoperative pain measured on a VAS scale showed there was less pain experienced in patients in Group B than in Group A (P<.01). Esthetic results measured on a VAS scale showed a higher compliance for patients in Group B than Group A (P<.01). Conclusions: The mini-invasive laparoscopic myomectomy described is, in our opinion, currently less invasive and more feasible than techniques usually used. Finally, this technique is a valid approach for the surgeon, and it gives women very acceptable aesthetic results
