Gastroduodenal fistulae and double pyloric canal

Abstract

Abstract. Four cases of endoscopically proven gastroduodenal fistulae (double pyloric canal) are presented, and ten case reports in the literature are reviewed.

Acquired Double Pylorus or Gastroduodenal Fistula

“…Endoscopy performed to confirm the lesion previously detected by X-ray and to ascertain its nature shows the two channels: the demon stration of their opening into the duodenum can be carried out by introduction of either polyethylene catheters (21) or the endoscope itself (27) into the two channels.…”

“…Hegedus et al (12) found 13 cases out of 7,932 radiological examinations within a period of 3 years (0.16%). In the first 8 months of 1978, 19 cases have been reported (12,13,17,21) and this is probably due to a greater awareness toward the problem. The case we describe has been detected out of an amount of 1,428 upper digestive endoscopies (0.09%).…”

Double pylorus from a chronic gastric ulcer: an interesting and rare case

“…GDF is an interesting and rare condition with radiological appearances of an antral or ulcerating carcinoma, Crohn's disease or lymphoma . The presence of previous ulceration and scarring should aid in distinguishing it from a malignancy.…”

Clinical characteristics of double pylorus

“…However, some cases have been reported in which DP was evidently a congenital anomaly. [1][2][3][4][5] The first case of DP was detected endoscopically. 6 To date, there have been sporadic reports of more than 100 cases.…”

“…However, about 20% of the patients underwent surgery because of refractory symptoms or other complications. 3,5,7,8 There is no long-term follow-up study of DP. 3,5,[7][8][9] The association of DP with other systemic diseases 8,9 and Helicobacter pylori infection 9 is not well characterized.…”
