Endoscopic hemostasis for hemorrhage from gastric cancer complicated by double-channel pylorus

Acute upper bleeding due to an unusual complication of peptic ulcer disease: double pylorus

“…In the majority of cases occurs on the lesser curve of the gastric antrum and connects to the superior wall of the duodenal bulb (2,3,5,8). There have been a few reports of double pylorus formed as a result of duodenal ulcer (9) and gastric cancer (10). The fistula in our case was lined by gastric epithelium and so it was a complication of a gastric ulcer.…”

A rare endoscopic finding: acquired double pylorus

“…Frequently, it is a complication of peptic ulcer disease, resulting from penetration of the peptic ulcer and the creation of a fistula between the duodenal bulb and the prepyloric antrum. Occasionally it may be congenital or secondary to gastric carcinoma [3,4]. The location of the second duct is commonly in the lesser curvature of the gastric antrum, near the anatomic pylorus.…”

A Case of Double Pylorus Caused by Recurrent Gastric Ulcers: A Long-Term Endoscopic Observation

“…While a congenital origin has been suggested in some cases, most of them are acquired (1,4). There have been a few reports of double pylorus formed as a result of duodenal ulcer and gastric cancer (1,5). However, in a majority of instances, it is a complication of gastric ulcer (1-3, 6-11).…”
