Management of Staple Line Leaks Following Laparoscopic Sleeve Gastrectomy for Morbid Obesity.

PURPOSES: Management of staple-line leaks following laparoscopic sleeve gastrectomy (LSG) is challenging and controversial. Guidelines for leak treatment are not standardized and often involve multidisciplinary management by surgical, medical and radiological methods. Herein we present our experience and proposed strategy for handling leaks after LSG.

PATIENTS AND METHODS: Retrospective data regarding LSG performed from April 2012 to October 2017 at the Surgical Oncology Division, Department of Human Pathology in Adulthood and Childhood ''G. Barresi'', University Hospital "G. Martino", University of Messina, Italy, were reviewed. The management approaches and the surgical, endoscopic, and percutaneous procedures used were examined. Outcomes measured included the prevalence of gastric leaks, radiological features, related morbidities and mortalities, hospital stay and management.

RESULTS: LSG was performed in 310 patients. Eight patients were managed for gastric leak within the 5-year period: 5 (1.6% overall prevalence) from our division, 3 referred from another hospital. All cases were successfully treated conservatively with combined CT/US-guided drainage using a locking pigtail catheter and endoscopic gastric stent positioning. Endoscopic therapy included the use of fully covered self-expanding esophageal metal stents (Hanarostent® 24 cm; M.I. Tech, Seoul, Korea) in addition to pigtail drains (Drainage Catheter Locking Pigtail 8F/21cm; Tru-Set® Ure-Sil, Skokie, IL, USA). Complete closure of the leak was achieved in all patients. The mean time from presentation to healing was 74 days ± 37.76 (SD). None of the patients underwent remedial surgery.

CONCLUSION: This study presents our management strategy for leak resolution in LSG patients. Based on our results, we strongly recommend the conservative and combined management of gastric leaks following LSG by endoscopic stenting and percutaneous drainage.
