The epidemic in obesity has led to an increase in number of so called bariatric procedures. Doctors are less comfortable managing an obese patient after bariatric surgery. Peri-operative mortality is less than 1%. The specific feature in the obese patient is that the classical signs of peritoneal irritation are never present as there is no abdominal wall and therefore no guarding or rigidity. Simple post-operative tachycardia in obese patients should be taken seriously as it is a WARNING SIGNAL. The most common complication after surgery is peritonitis due to anastomotic fistula formation. This occurs typically as an early complication within the first 10 days post-operatively and has an incidence of 1-6% after gastric bypass and 3-7% after sleeve gastrectomy. Post-operative malnutrition is extremely rare after restrictive surgery (ring, sleeve gastrectomy) although may occur after malabsorbative surgery (bypass, biliary pancreatic shunt) and is due to the restriction and change in absorption. Prophylactic cholecystectomy is not routinely carried out during the same procedure as the bypass. Superior mesenteric vein thrombosis after bariatric surgery is a diagnosis which should be considered in the presence of any postoperative abdominal pain. Initially a first etiological assessment is performed (measurement of antithrombin III and of protein C and protein S, testing for activated protein C resistance). If the least doubt is present, a medical or surgical consultation should be requested with a specialist practitioner in the management of obese patients as death rates increase with delayed diagnosis.

A 33-year-old man presented with hepatic encephalopathy and was diagnosed to have a noncirrhotic extrahepatic portosystemic shunt (NCPSS). He presented with abdominal pain 16 months after the NCPSS diagnosis. Computed tomography revealed thrombosis between the intrahepatic portal vein and the left internal iliac vein, including the NCPSS, and varices of the sigmoid colon. Thrombosis was treated with danaparoid sodium and antithrombin III followed by edoxaban. After treatment, the thrombosis disappeared from the intrahepatic portal vein, but it remained in the NCPSS. The sigmoid colon varices were followed up without any treatment. Follow-up is needed in NCPSS patients in order to make an early detection of complications.
