Gastric and pancreatoduodenal resection for malignant lesions after previous gastric bypass-diagnosis and methods of reconstruction

Gastric and pancreatoduodenal neoplasms after previous gastric bypass, although rare, will most likely increase as the number of bariatric operations increases. A high index of suspicion and focused diagnostic testing are key in identifying these lesions. Resection is feasible and safe but could require complex gastric and pancreatobiliary reconstruction.
