Gastric leak after sleeve gastrectomy: risk factors for poor evolution under conservative management.

Background: Gastric leak (GL) is the most highly feared early postoperative complication after sleeve gastrectomy (SG), with an incidence of 1% to 2%. This complication may require further surgery/endoscopy, with a risk of management failure that may require additional surgery, including total gastrectomy, leading to a risk of mortality of 0% to 9%.

Objectives: Assess the impact of factors that may lead to a poorer evolution of GL.
