Diagnosis and management of gastric leaks after laparoscopic sleeve gastrectomy for morbid obesity

Abstract

Background: Laparoscopic sleeve gastrectomy (LSG) is increasingly being recognised as a valid stand-alone procedure for the surgical management of morbid obesity. The leak rate from the gastric staple line ranges from 1.4% to 20%. From our experience of management of LSG leaks, we have been able to formulate an algorithm-based approach to the management of these patients.

Methods: All patients referred to our hospital within a 24-month period with a diagnosis of gastric staple line leak in the background of a previous LSG were included in the study. A retrospective case note review was undertaken for these patients and an algorithm formulated.

Results: There were fourteen patients in the study. There were four males and ten females. Patients were managed with a combination of laparotomy, laparoscopy, endoscopic covered stenting, percutaneous radiologically guided drainage,jejunal enteric feeding and total parenteral nutrition. In five patients, re-look laparoscopy or laparotomy with washout and drainage was performed. The remaining eight patients were managed conservatively. There were no deaths.

Conclusions: Although it is often disappointing when LSG leaks do occur, with adherence to the basic tenets of the surgical management of enterocutaneous fistulae as well as early detection and a high index of suspicion, these complications can be successfully managed using an algorithm-based multi-disciplinary team approach.
