Tubular enteric duplication presenting as jejuno-colic fistula in a 38 years old adult

Colo-enteric fistula is a rare entity, malignancy being the commonest cause. Both adenocarcinoma and rarely lymphoma have been known to cause it. Benign jejuno-colic fistulas are mostly secondary to tuberculosis or inflammatory bowel disease. Here we present a case of a young adult male, who presented with altered bowel habits. Colonoscopy and oesophago-gastro-duodenoscopy (OGD) revealed a fistulous tract between the proximal jejunum to the splenic flexure of colon. Surgery revealed a small fistulous connection between the above-mentioned parts of the bowel about 1cm long. Histopathology demonstrated it to have all the layers of the intestinal anatomy, hence indicating a possibility of congenital aetiology, probably enteric duplication of communicating tubular variety.

Primary Malignant Jejunocolic Fistula: A Rare Presentation

Primary malignant fistulas of the gastro-intestinal tract are very rare. Usually they are secondary to diverticular disease, crohn'sgastric ulcer, lymphoma, post surgery etc. Here we have reported a very rare case of primary malignant fistula with primarylocated at recto-sigmoid junction, leading to a fistulous tract between the jejunum and sigmoid colon. We have briefed on thecourse of the disease, investigations done and management of the same.
