A Sigmoid-Urachal-Cutaneous Fistula after Acute Diverticulitis

Abstract

The urachus is an embryonic remnant of communication between the bladder and the umbilicus; it usually obliterates and becomes a fibrous cord, but the incomplete obliteration or partial recanalization leads to the development of anomalies such as urachal cyst or patent urachus. As a consequence of the diverticulitis episode, the sigmoid colon or peridiverticular abscess may adhere to the patent urachus and develop a colourachal fistula with feculent umbilical drainage. Here, we evaluated a case of sigmoid-urachal-cutaneous fistula in the light of the current literature. (JAREM 2015; 5: 83-4)
