[Fistulae in diverticular disease of the colon].

Fistulas in colon diverticular disease are a not uncommon complication, that arise spontaneously in the evolution of a diverticulitis, and also as a complicated dehiscence of surgical anastomosis. The intermediate step of a fistula is a deep abscess that finds through the parietal layers of abdomen or towards other adjacent organs. So the surgeon can be confronted with external and internal and complex fistulas. As for diagnostic manoeuvres, the surgical choices are outside a rigid schedule, and is on the personal sensibility of the surgeon.
