Use of Bidirectional Barbed Suture in Laparoscopic Myomectomy: Evaluation of Perioperative Outcomes, Safety, and Efficacy

STUDY OBJECTIVE To compare perioperative outcomes during laparoscopic myomectomy using a bidirectional barbed suture vs conventional smooth suture. DESIGN Retrospective analysis of 138 consecutive laparoscopic myomectomies performed by a single surgeon over 3 years (Canadian Task Force classification II-2). SETTING Major university teaching hospital. PATIENTS One hundred thirty-eight women with symptomatic uterine myomas. INTERVENTIONS In women undergoing laparoscopic myomectomy from February 2007 through April 2010, conventional smooth sutures were used in 31 patients, and bidirectional barbed suture in 107 patients. MEASUREMENTS AND MAIN RESULTS The primary indications for laparoscopic myomectomy in either group were pelvic pain or pressure and abnormal uterine bleeding. Use of bidirectional barbed suture was found to significantly shorten the mean (SD) duration of surgery (118 [53] minutes vs 162 [69] minutes; p <.05) and reduce the duration of hospital stay (0.58 [0.46] days vs 0.97 [0.45] days; p <.05). No significant differences were observed between the 2 groups insofar as incidence of perioperative complications, estimated blood loss, and number or weight of myomas removed during surgery. CONCLUSION Use of bidirectional barbed suture seems to facilitate closure of the hysterotomy site in laparoscopic myomectomy.

Robot-assisted laparoscopic myomectomy compared with standard laparoscopic myomectomy.

OBJECTIVE: To compare surgical outcomes of laparoscopic myomectomy and robot-assisted laparoscopic myomectomy. METHODS: Retrospective cohort study of 115 consecutive laparoscopic myomectomy and 174 consecutive robot-assisted laparoscopic myomectomy performed at Brigham and Womens Hospital over a period of 31 months. Uterine incisions were closed in multiple layers (running barbed suture was used for most cases in the laparoscopic myomectomy group). Surgical outcomes measured included operative time, estimated intraoperative blood loss, length of hospital stay, and perioperative complications. Odds ratios and 95% confidence intervals were calculated from multivariable logistic regression models; adjusted geometric means were estimated from linear regression models on logged outcomes because of skewed distributions. RESULTS: Surgical groups were similar in age, body mass index, and leiomyoma characteristics. Robot-assisted laparoscopic myomectomy had significantly longer operative time than laparoscopic myomectomy (adjusted geometric mean of 195.1 compared with 118.3 minutes, P<.001) and higher estimated blood loss (adjusted geometric mean of 110.0 compared with 85.9 mL, P=.04), but postoperative complications were similar. CONCLUSION: Robot-assisted laparoscopic myomectomy and laparoscopic myomectomy have similar operative outcomes in a high-volume surgical practice. Operative time and intraoperative estimated blood loss were significantly greater in the robot-assisted laparoscopic myomectomy group, but the level of statistical significance for intraoperative estimated blood loss was marginal and the clinical significance was undetermined. Use of barbed suture in the laparoscopic myomectomy group may account for these differences. LEVEL OF EVIDENCE: II

Bidirectional barbed suture: an evaluation of safety and clinical outcomes.

The use of bidirectional barbed suture appears to be safe for closing the vaginal cuff in a total laparoscopic hysterectomy and for closing the hysterotomy site during laparoscopic myomectomy.

Small Bowel Obstruction Associated With Use of a Gelatin-Thrombin Matrix Sealant (FloSeal) after Laparoscopic Gynecologic Surgery

We report 2 cases of laparoscopic gynecologic procedures, complicated by small bowel obstruction possibly related to use of a hemostatic agent. The cause was most likely from excess material not incorporated in the hemostatic clot at the site of application. Gentle irrigation and removal of excess material from the site of application is recommended by the manufacturer of FloSeal and may reduce the risk of postoperative adhesion formation and small bowel obstruction.
