A thirty-five-year-old male patient presented 3 days post Roux en y gastric bypass by severe abdominal pain & vomiting: (A) & (B) UGIS revealed: evidence of leakage track extending upwards, to the left and posterior from the gastric pouch to a large left upper quadrant collection. (C) & (D) MSCT axial images revealed; evidence of contrast leakage at the site of gastrojejunal anastomosis with a thin walled large air and contrast filled collection at the left hypochondrium and pneumoperitoneum. (E, F) shows; successful insertion of naso-enteric tube (blue arrow) under fluoroscopic guidance for drainage of the leak (white arrow). (a) and (b) UGIS and (c) and (d) MSCT follow up 1 week after insertion of a nasoenteric tube for drainage of the gastrogastric fistula for the same case show significant decrease in size of the fluid and air collections seen in the previous images but there is residual contrast at the excluded stomach (white arrow in c) due to fistulous tract formation which developed between the gastric pouch and excluded stomach probably through the jejunal stump.
