Eosinophilic gastroenteritis causing stenosis of bulbo-duodenal junction: medical and endoscopic management

Abstract

Eosinophilic gastroenteritis is a rare disease characterised by tissue eosinophilia that can involve any layer or part of the gut from the oesophagus to the rectum. In Saudi Arabia, the disease has not been reported in the literature before. We report the disease entity as an unusual cause of gastric outlet obstruction. A 50-year-old man was admitted through the gastrointestinal clinic with complaints of epigastric pain associated with dyspepsia for 1 month, and weight loss of 4 kg in 2 months. Examination revealed only the epigastric tenderness on deep palpation. Laboratory investigations including full blood count, liver function tests and renal function tests were normal. Gastroscopy disclosed stenosis of the second and third part of the duodenum. Biopsies were taken and the patient underwent endoscopic dilatation of the pylorus and duodenal bulb. Histopathology showed chronic active eosinophilic inflammation. The patient was successfully treated with a tapering course of steroids and had a complete recovery post-endoscopic dilatation.

Circumferential Stenosis of the Second Part of the Duodenum Caused by Eosinophilic Gastroenteritis

“…However, the duodenum, jejunum, and colon were also involved in this case. Ashraf et al reported a case of EGE causing stenosis of the second and third part of the duodenum (21). EGE was diagnosed by a pathological examination using biopsy specimens after endoscopic dilation in Ashrafs' case.…”

Unusual presentations of eosinophilic gastroenteritis: Two case reports

“…The patient underwent dilation of the stenotic area with a pneumatic balloon in combination with a pharmacological treatment course (i.e., esomeprazol, domperidone, loratadine, and prednisone) (61). This was the first reported case in which the treatment involved an endoscopic intervention for a gastrointestinal tract obstruction due to EG, thereby circumventing the need for surgical resection.…”
