An operative case of gastric cancer with ectopic bile duct drainage in the lesser curvature of the stomach

TL;DR

A rare case of gastric cancer with an unusual bile duct drainage in the stomach is reported, highlighting the need for careful monitoring.

Contribution

This paper presents a rare clinical case of gastric cancer associated with ectopic bile duct drainage, contributing to the understanding of such anomalies.

Findings

A 67-year-old man had gastric cancer with ectopic left extrahepatic bile duct drainage in the stomach.

The patient underwent distal gastrectomy and bile duct jejunostomy with no post-operative complications.

The patient remained recurrence-free for 39 months, suggesting possible clinical implications of ectopic bile ducts in gastric cancer.

Abstract

Among the various anomalies of the biliary system, a double common bile duct with ectopic drainage in the stomach is rare. Furthermore, ectopic bile ducts are extremely rare in gastric cancers.

A 67-year-old man was admitted to our hospital with gastric cancer and ectopic left extrahepatic bile duct drainage in the stomach. Pre-operative testing revealed no communication between the intrahepatic bile ducts. Distal gastrectomy and bile duct jejunostomy were performed. The post-operative course was uneventful, and the patient did not exhibit recurrence for 39 mo.

Although it is uncertain whether sustained bile exposure from an ectopic bile duct is related to gastric cancer, short-term follow-up might be necessary because of the possibility of gastric cancer.
