This case report describes a 26-year-old pregnant woman who presented with an acute abdomen and positive blood cultures for Bacteroides fragilis at 16 weeks of gestation. Surgical exploration revealed a colouterine fistula with pelvic sepsis, while histological analysis of resected specimens showed extensive uterine adenomyosis and cecal endometriosis forming the fistulous tract. The condition was further complicated by severe chorioamnionitis and endomyometritis resulting from the infection spreading through the abnormal connection. This paper is centrally about endometriosis — specifically illustrating a rare complication where intestinal endometriosis leads to a colouterine fistula associated with adenomyosis.

Abstract

In Brief BACKGROUND: Intestinal endometriosis may be complicated by bowel obstruction, colonic rupture, sepsis, and rarely, malignant transformation. Fistula formation is extremely rare. CASE: A 26-year-old woman presented at 16 weeks of gestation with an acute abdomen suggestive of ruptured appendicitis. Blood cultures were positive for Bacteroides fragilis. At laparotomy, she was found to have a colouterine fistula with pelvic sepsis. The resected specimens demonstrated extensive uterine adenomyosis and endometriosis of the cecum, with a fistulous tract lined by endometriosis and suppurative inflammation extending from the cecum to the uterine endometrial cavity associated with severe chorioamnionitis and endomyometritis. CONCLUSION: This case illustrates a rare complication of colouterine fistula secondary to intestinal endometriosis. We report a patient with a unique complication of pregnancy secondary to a colouterine fistula in an area of endometriosis with associated acute chorioamnionitis.
