Gastroduodenal Intussusception Resulting from Large Hyperplastic Polyp

Abstract

Gastroduodenal intussusception is an infrequent cause of gastrointestinal obstructive disease. Benign neoplasms, gastrointestinal stromal tumors and pedunculated adenocarcinomas of less than 5 cm have been reported to cause gastroduodenal intussusception. We report a case of 76-year-old woman who was presented with a 3-day history of nausea and vomiting due to upper gastrointestinal obstruction. Computed tomography revealed gastroduodenal intussusception with the transpyloric herniation of alarge gastric hyperplastic polyp. The patient underwent laparoscopic wedge resection with the eversion method.

Gastroduodenal Intussusception Secondary to Hyperplastic Polyps with Adenocarcinoma

“…12 Gastroduodenal intussusception is uncommon because it is unusual for a mass in the stomach to intussuscept into a much smaller duodenal lumen. 1,2,4 Most such cases are secondary to a benign lead point such as gastrointestinal stromal tumour, lipoma, hyperplastic polyp, or Ménétrier disease. [1][2][3][4][5] Gastroduodenal intussusception secondary to gastric carcinoma is uncommon.…”

[1][2][3][4][5] Gastroduodenal intussusception secondary to gastric carcinoma is uncommon. 6,7 Clinical symptoms of gastroduodenal intussusception vary from asymptomatic, mild chronic intermittent epigastric pain, to acute gastric outlet obstruction with vomiting, to pancreatitis.…”

“…6,7 Clinical symptoms of gastroduodenal intussusception vary from asymptomatic, mild chronic intermittent epigastric pain, to acute gastric outlet obstruction with vomiting, to pancreatitis. [1][2][3][4][5][6][7][8] One patient with gastroduodenal intussusception secondary to a large hyperplastic polyp was reported to present with acute symptoms. 1 Our patient experienced only mild symptoms despite similar underlying pathology.…”

“…1,2 Most such cases have an underlying condition (benign or malignant) as a lead point. [1][2][3][4][5][6][7][8] Gastric hyperplastic polyps are the most common type of non-fundic gland gastric polyps incidentally found during endoscopy. 9,10 They usually occur in the antrum and are rarely associated with dysplasia or carcinoma, with the reported risk being 0.6% to 19%.…”

“…2 Two cases of gastroduodenal intussusception caused by hyperplastic polyp have been reported, despite its high prevalence and its antral location. 1,11 We report a case of gastroduodenal intussusception secondary to conglomerate hyperplastic polyps that associated with severe dysplasia and focal intramucosal adenocarcinoma.…”
