A Case of Double Pylorus Associated with Ectopic Pancreas Presenting with Gastric Ulcer Bleeding / 대한소화기내시경학회지

ABSTRACT

Duplication of the pylorus is one of the rare anormalies of the intestinal tract. Most of the reported cases are secondary double pylorus caused by peptic ulcer. However, double pylorus may be a congenital anomaly sometimes combined with ectopic pancreas. Recently, we experienced a case of double pylorus combined with ectopic pancreas in a 76-year-old man. The patient presented with gastric ulcer bleeding. An esophagogastroduodenoscopy confirmed the presence of double pylorus, but subsequent endoscopic hemoclipping failed to control bleeding from an ulcer on the lesser curvature of the prepyloric antrum. The microscopic examination of the surgically resected specimen showed an ectopic pancreatic tissue in the gastric wall near the ulcer lesion. We report this case with a collected review of the Korean literature.
