Gastric tumour causing gastroduodenal intussusception - Laparoscopic management

Area of Science:

• Gastroenterology
• Surgical Oncology
• Abdominal Imaging

Background:

• Adult gastroduodenal intussusceptions are exceedingly rare, often presenting with non-specific symptoms.
• Gastric gastrointestinal stromal tumors (GISTs) are uncommon neoplasms, and their presentation as gastroduodenal intussusception is atypical.
• Early and accurate diagnosis is challenging due to the subtle and overlapping clinical features with other gastrointestinal conditions.

Purpose of the Study:

• To report a rare case of gastric antral GIST causing gastroduodenal intussusception in an elderly male.
• To discuss the diagnostic challenges and management strategies for this rare clinical entity.
• To evaluate the feasibility and outcomes of laparoscopic surgery for gastroduodenal intussusception secondary to GIST.

Main Methods:

• Case report of an elderly male with symptoms of gastric outlet obstruction.
• Diagnostic workup included imaging and endoscopy to identify the cause.
• Surgical intervention involved laparoscopic distal gastrectomy for definitive treatment.

Main Results:

• Diagnostic imaging and endoscopy confirmed a gastric antral GIST leading to irreducible gastroduodenal intussusception.
• Laparoscopic distal gastrectomy was successfully performed as the definitive management.
• The laparoscopic approach offered comparable oncological outcomes to open surgery, with improved cosmesis and recovery.

Conclusions:

• Gastric GIST presenting as gastroduodenal intussusception is a rare but important differential diagnosis in patients with gastric outlet obstruction.
• Laparoscopic surgery is a feasible and effective treatment option for gastroduodenal intussusception caused by GIST, providing excellent outcomes.
• Minimally invasive surgery in such cases leads to faster recovery and better cosmetic results compared to traditional open procedures.
