Objective: To evaluate the efficacy of a simple intra-operative test (white banner test) for the detection of a leak during laparoscopic sleeve gastrectomy.
Design: A prospective case series study.
Setting: Obesity center at Soran private hospital, Erbil, Iraq, during the period from January 2017 to June 2019.
Participants: eighty patients underwent the white banner test during laparoscopic sleeve gastrectomy. The records of intraoperative findings and post-operative follow up were analyzed.
Patients and methods: After completing the sleeve process and hemostasis, a gauze of 4*12 cm was introduced through the 12mm trocar and displayed along the course of remaining sleeved stomach, nasogastric tube inserted to the upper portion of the stomach, compression of the pylorus by grasper against the vertebrae, 100 milliliters of saline stained by methylene blue dye were injected slowly by the anesthetist through the nasogastric tube, waiting for 30 seconds, any discoloration of the gauze was recorded and the site of leak (if any) was identified and managed. If the gauze appeared white, gauze withdrawn and the procedure finished.
Results: In 80 patients, only two patients showed a blue spot at the gauze, which were fixed by suture. In all other patients, the gauzes were completely clean and (white). Postoperatively no early leak was detected.
Conclusion: This is a simple and not time-consuming intraoperative procedure that can be used to detect intra-operative leaks during laparoscopic sleeve gastrectomy.
