Primary Adenocarcinoma of Duodenum Located in Third Portion Cured by Wedge Resection

ABSTRACT

Primary adenocarcinoma of duodenum is an uncommon neoplasm. Besides its rarity, vague symptoms and signs with the lack of physical findings can delay diagnosis and result in poor treatment outcome. Aggressive surgical managements including pancreaticoduodenectomy was generally recommended for localized cancers despite high operational mortality. However, if early stage cancer is detected, wedge resection can be a therapeutic option. The authors encountered a 2.5x1.5 cm sized subepithelial tumor like mass with spontaneous bleeding and central dimpling located in the third portion of duodenum on esophagogastroduodenoscopy. After repeated deep biopsy, the patient underwent wedge resection and regional lymph node dissection of the duodenum. Finally, the mass was proven as adenocarcinoma and the patient remains in good condition without recurrence for over 2 years. Due to it's low incidence and high mortality, meticulous endoscopic examination of duodenum is essential for early diagnosis and limited operational methods may improve survival and quality of life of patients.
