“…Previous studies have identified GISTs in postop bariatric patients, though these were either c-kit-negative tumors, or after bariatric surgery other than RYGB. 2-4 Our case is deemed significant as it presents as one of the few c-kit + GISTs arising from the excluded stomach remnant post-RYGB to be described in the literature.…”

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the GI tract. Despite this, they rarely occur, accounting for only 1% to 3% of all gastrointestinal tumors. This report describes a 53-year-old female patient with surgical history of Roux-en-Y gastric bypass (RYGB) who presented with right upper quadrant abdominal pain. CT imaging revealed a large 20 × 12 × 16 cm mass in the excluded stomach remnant. Ultrasound-guided biopsy confirmed this mass to be a GIST. The patient was treated surgically with exploratory laparotomy with distal pancreatectomy, partial colectomy, partial gastrectomy, and splenectomy. There are currently only 3 known reported cases of GISTs after RYGB.
