Diagnosis and treatment of a patient with gastrocolic fistula in chronic intestinal ischaemia are reported. A gastrocolic fistula secondary to occlusion of splanchnic arteries has not been described before. The surgical management consisted of a revascularization procedure of the superior mesenteric artery and the common hepatic artery by a sequential saphenous graft from the right common iliac artery. Occlusion of splanchnic arteries should be excluded prior to surgery for benign gastrocolic fistula.
