Iatrogenic duodenocolic fistula.

Benign duodenocolic fistula is a rare, surgically curable, but potentially lethal entity. Etiology, symptomatology, diagnosis and management are discussed. The authors describe the fifth reported case of an iatrogenic cause and review the literature on benign duodenocolic fistula. Early diagnosis and aggressive nutritional and surgical management are necessary to avoid serious morbidity and malnutrition leading eventually to death.
