Abstract

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.

摘要

胃肠道间质瘤（GISTs）是胃肠道最常见的间叶性肿瘤。尽管如此，它们很少发生，仅占所有胃肠道肿瘤的 1%至 3%。本报告描述了一位 53 岁女性患者，她有 Roux-en-Y 胃旁路（RYGB）手术史，表现为右上腹疼痛。CT 成像显示在已排除的胃残端有一个 20×12×16cm 的大肿块。超声引导活检证实该肿块为 GIST。患者接受了手术治疗，行剖腹探查术，包括胰十二指肠切除术、部分结肠切除术、部分胃切除术和脾切除术。目前仅报道了 3 例 RYGB 后 GIST 的病例。
