The evolution of surgical treatment for chronic leak following sleeve.

BACKGROUND

Leak is estimated to be the most severe complication of laparoscopic sleeve gastrectomy (LSG), with sporadic failure of endoscopic techniques. In such cases, an aggressive management with surgical reconstructive procedures can be proposed to patients in whom all the conservative endoscopic techniques failed.

OBJECTIVES

The purpose of the present study was to report our experience with surgical approach for the treatment of chronic leak after LSG.

SETTING

University hospital, France.

METHODS

Between January 2013-December 2019, 21 consecutive patients underwent reconstructive surgery for the treatment of chronic leak after LSG. The initial intervention, the endoscopic approach, and the definitive surgical repair were carefully reviewed.

RESULTS

Twenty-one patients (17 women) with a mean (standard deviation [SD]) age of 42.7 years (9.81) and a mean (SD) body mass index (BMI) of 27.3 (5.2) kg/m underwent reconstructive surgery for persistent fistula. Seventeen patients (81%) had their early LSG performed in another hospital. Endoscopic treatment was represented by the pigtail drain or stent in 9 cases each, ovesco in 8 cases, and glue for 2 patients. The reconstructive surgery was performed within 6 months in 8 cases; between 6-12 months in 6 cases; between 1-3 years in 4 cases, and >3 years in 3 cases. There were 14 fistulo-jejunostomy (66.7%), 5 Roux-en-Y gastric bypass (23.8%), and 2 total gastrectomies (9.5%). The operative time was between 99 minutes and 5.5 hours (mean = 216.2, median = 225 min). The hospital stay ranged from 5-30 days (mean = 12.67, median = 11 d) and the surgical reintervention rate was 23.8% (5/21 patients), including 1 case of recurrent hemorrhage requiring 3 surgical operations over 1 month of postoperative follow-up. No postoperative mortality was recorded.

CONCLUSIONS

Surgery should be considered in case of failure of the endoscopic treatment of chronic leak after LSG. Further research is needed to clearly identify the appropriate treatment, but in our experience the fistulo-jejunostomy approach shows a low morbidity rate.
