Successful palliation of diarrhea owing to malignant duodenocolic fistula by octreotide.

D uodenocolic fistula (DCF) is a very rare entity characterized by fistulous communication between duodenum and transverse colon; DCF owing to metastatic lymph nodes is even rarer. Intractable explosive diarrhea is the most consistent and troublesome symptom in DCF. Treatment is mostly palliative. We present the case of a patient with malignant DCF owing to lymph node metastasis from carcinoma of the rectum. This patient’s diarrhea was successfully controlled with octreotide. We believe that this is the first reported case of malignant DCF arising due to metastatic lymph nodes and successfully palliated by octreotide.
