摘要

雙幽門症是一種腸胃異常，通常指在胃前庭與十二指腸球部間出現第二個通道，病例報告以後天性居多。我們的病例為一位五十八歲男性病患，因為解黑便而住院。經由胃鏡檢查顯示，在胃前庭幽門前區有一凸起腫塊，且合併有活動性潰瘍。由於懷疑為粘膜下腫瘤，故進行組織切片檢查，但結果僅為慢性胃炎。經過一個月的乙型阻斷劑治療，第二次胃鏡檢查仍只有表淺性胃炎。在往後四年的追蹤裹，由於不規則服用藥物治療，從第四次到第八次的胃鏡檢查，均顯示有另一通道沿胃前庭小彎進入十二指腸。藉由連續追蹤的胃鏡及上消化道攝影檢查，我們提出此雙幽門病例的發展過程。

Double pylorus is a gastrointestinal abnormality in which a second channel connects the antrum of stomach to the duodenal bulb, and appears to be an acquired lesion in the majority of cases reported. Herein, we present a case of double pylorus. The patient was a 58-year-old male who was admitted with complaints of tarry stool passage. Panendoscopic study disclosed a protruding mass with an A2 ulcer at prepyloric antrum and submucosal tumor had to be ruled out initially. Tissue biopsy showed merely chronic gastritis. The next follow-up panendoscopy after one-month treatment with H2-blocker simply revealed superficial gastritis. By the 4th to 8th endoscopy during the following four years, a second hole in lesser curvature side of antrum was persistently found. We present this case of evolving double pylorus with a series of panendoscopic studies and barium meal study of UGI series.
