    Abstract:
    BACKGROUND: Laparoscopic bariatric surgery relies on technically challenging intracorporeal suturing for critical parts of the operation. Barbed sutures have been developed to provide an alternative to suturing for certain manoeuvres within a procedure. Barbed sutures theoretically negate the need for knot tying and allow for continuous application of tension; however the barbs can unintentionally adhere to surrounding tissues. We describe a case series of three patients who developed V-Loc™ (barbed) suture related small bowel obstruction (SBO) to promote awareness of this unusual but preventable complication. METHODS: Medical records of patients diagnosed with V-Loc™ related SBO between 2018 and 2021 at a tertiary centre were reviewed. Data regarding presentation, diagnosis, management and outcomes were obtained. RESULTS: Three patients were identified where V-Loc™ sutures were aetiologically related to early post-surgical small bowel obstruction secondary to small bowel adherence to barbed suture tail or adhesions between barbed suture tail and unintended viscera. In these cases, non-absorbable V-Loc™ sutures were used to close the small bowel mesenteric defect at Roux-en-Y gastric bypass surgery. All patients required adhesiolysis at re-look laparoscopy prior to resolution. All patients were discharged home well after relook laparoscopy. CONCLUSION: Overly long or exposed V-Loc™ suture tails can result in SBO following laparoscopic bariatric surgery. Cutting the suture tail as close as practical to the final throw of the suture and/or covering exposed suture ends may prevent this complication.
