A case of a bleeding benign gastrocolic fistula in 2014

INTRODUCTION

In the era of proton pump inhibitors in the treatment of peptic ulcer disease, the incidence of a gastrocolic fistula arising from unoperated gastric ulcers is extremely low.

PRESENTATION OF CASE

We present the case of a 68-year old farmer who presented with melaena and was found to have a benign gastrocolic fistula in the setting of untreated peptic ulcer disease, chronic NSAID ingestion and heavy alcohol intake. The diagnosis was made by gastroscopy. En bloc surgery was undertaken due to the size of the fistula and concomitant significant bleeding of the ulcer which would not have made it amenable to medical management.

DISCUSSION

The symptoms of a gastrocolic fistula are undifferentiated and the diagnosis can easily be missed in the setting of other complications such as bleeding or perforation of a hollow viscus. Barium enamas are the most accurate for the diagnosis but gastroscopy with biopsy is usually performed to rule out malignancy. The mainstay of treatment is usually surgical, though patients can be medically managed if he/she is not a surgical candidate.

CONCLUSION

Benign gastrocolic fistulas are rare and its diagnosis is easily missed.
