摘要

Objectives

To report a rare case of adult gastroduodenal intussusception caused by a gastric gastrointestinal stromal tumor (GIST) and review its diagnostic and therapeutic approaches. 

Methods

We present a 68-year-old female with gastroduodenal intussusception secondary to a gastric GIST, diagnosed through combined endoscopy and computed tomography (CT). A systematic PubMed review identified 28 published cases, which were analysis for clinical presentation, imaging findings, and management strategies.

Results

The patient initially underwent laparoscopic-endoscopic cooperative surgery, which was unsuccessful and required conversion to open partial gastrectomy. Intraoperative findings confirmed a fundus mass extending into the duodenum, with histopathology confirming a low-risk GIST. Among the reviewed cases, all involved GISTs of gastric origin. Diagnostic evaluation consistently relied on CT and endoscopy, with surgical approaches varying based on tumor characteristics.

Conclusions

Gastric GISTs are a rare but clinically significant cause of adult gastroduodenal intussusception, typically necessitating surgical intervention. Multimodal imaging, particularly CT, plays a crucial role in preoperative diagnosis, while histopathological examination remains essential for definitive diagnosis and risk stratification. Treatment should be individualized based on tumor size, location, and patient factors.
