Treatment for obesity has several options. Surgical techniques have shown to be the most effective. Of these techniques, the laparoscopic Roux-en-Y gastric bypass (LRYGB) and the laparoscopic sleeve gastrectomy (SG) are the two most performed.

Gastrointestinal (GI) leak after bariatric surgery is one of the most life-threatening surgical complications, with a mortality rate of 14%, occurring when there is discontinuity of tissue apposition at the site where the tissue has been stapled and divided. Leaks are more likely due to tissue ischemia caused by tension on the anastomosis, distal bowel obstruction, or hematoma.

The incidence of leak after bariatric surgery is 2.4–4.9% and varies according to the type of surgery.

Leaks are a major source of morbidity and mortality for patients, and management is often complex, resulting in longer hospitalizations and increases in overall complication rates. On the data of 12799 LSGS, the International Sleeve Gastrectomy Expert Panel Consensus Statement 2011, the leak rate was 1.06%, but the leak rate can vary between 1% and 3% for primary procedure and more than 10% in revision procedures.
