Abstract
- A 39-year-old man presented with dizziness and melena for 2 months. Abdominal CT scan showed constrictive wall thickening with enhancement and proximal loop dilatation of the jejunum. On endoscopic examination, there was large amount of bile stained fluid in duodenum. Enteroscopy using pediatric colonoscope demonstrated an encircling mass with obstruction approximately 20 cm distal to the ligament of Treitz. Endoscopic jejunal biopsy showed moderately differentiated adenocarcinoma. Small intestinal adenocarcinoma is uncommonly encountered in clinical practice. Because small intestine is relatively inaccessible via routine endoscopy, diagnosis of small intestinal neoplasm is often delayed for several months after the onset of symptoms. Most of the patients are diagnosed in advanced stage. Therefore, when a small bowel neoplasm is suspected, enteroscopy is the most useful study. If enteroscope is not available, enteroscopy using pediatric colonoscope may permit earlier preoperative diagnosis. We report a case of primary jejunal adenocarcinoma diagnosed by endoscopic biopsy using pediatric colonoscope.
