Sleeve gastrectomy is currently a stand-alone bariatric procedure with a low complication profile. A rare complication of leak following sleeve gastrectomy was reported in this study. A 34-year-old male patient with body mass index of 69.9 was admitted to hospital 4 months after sleeve gastrectomy with epigastric pain and fever, and leak at the gastroesophageal junction was observed on computed tomography scan. In addition, he had splenic vein thrombosis with infected partial splenic infarction with abscess formation. Endoscopic stent was used to cover the leak and percutaneous drainage of the splenic abscess was performed. Partial infarction of the spleen is not a rare occurrence after laparoscopic sleeve gastrectomy. However, abscess development is extremely rare. Familiarity with these rare complications will allow for prompt diagnosis and treatment.Keywords: Bariatric surgery, gastrectomy leak, laparoscopic sleeve gastrectomy.
