Minimally invasive treatment of gastric leak after sleeve gastrectomy

Abstract

Obesity is a leading problem in Western countries, and laparoscopic sleeve gastrectomy (SG) is the most commonly used procedure for the surgical management of morbid obesity. SG is recognised as one of the safest and most effective bariatric procedures but it is limited by a rate of gastric leaks (GL) ranging from 1.4% to 20%. No international consensus exists about the treatment of GL. This paper reports our experience with the noninvasive management of GL. From July 2004 to December 2010, 16 patients with GL after SG were referred to our unit. All patients underwent contrast radiography (Gastrografin) and computed tomography (CT) examination. On the basis of the radiographic findings, patients were divided into those eligible for drainage and those not eligible. Twelve patients (75%) were eligible for percutaneous drainage. Of these, seven patients (44%) were successfully treated with percutaneous drainage alone, whereas five patients (31%) required placement of a covered stent due to incomplete resolution of the collection. After 1009.8±456.7 days of follow-up, one patient died from a cardiovascular event and two patients required a bilio-pancreatic-digestive bypass (BPD-BP). Twelve patients (75%) were in an excellent state of health with significant reduction of their body mass index (BMI). Our experience confirms the value of an algorithm based on patient eligibility for percutaneous drainage in the treatment of GL. The patient's general condition and in particular the presence of sepsis supports the value of this approach in preference to the conventional surgical approach.
