Early duodenal carcinoma successfully resected by endosopic mucosal resection / 대한내과학회지

ABSTRACT

Primary duodenal adenocarcinoma is rare disease with a poorly defined natural history. It represents less than 0.35% of all gastrointestinal tract malignant neoplasms and accounts for up to 33 to 45% of small bowel cancers. Diagnosis is always late because of the non-specific symptoms, consequently leading to poor prognosis. Surgical resection is the only potentially curative treatment, but not all patients whose tumor is removed necessarily survive long term. Recent widespread use of endoscopy has increased early detection of duodenal adenocarcinoma. Thanks to early detection, duodenal adenocarcinoma can now be treated endoscopically, which allows the patient's quality of life to be maintained. We have experienced one case of the primary early duodenal adenocarcinoma of the first portion, which was diagnosed by biopsy with endoscopic examination as part of a routine medical evaluation and was resected by endoscopic mucosal resection technique. We report the first primary early duodenal adenocarcinoma successfully treated by EMR method in Korea.
