Uterocutaneous fistula after surgical treatment of an incomplete abortion: methylene blue test to verify the diagnosis

Abstract

Introduction: Uterocutaneous fistula is an extremely rare clinical condition that can be seen after pelvic or uterine surgery. It can also complicate some obstetric procedures.

Case: We report of an unusual case of an uterocutaneous fistula that developed in a multiparous woman after surgical evacuation of an incomplete first trimester septic abortion. The fistula tract was depicted on computed tomography, and to verify the diagnosis methylene blue was given through a transcervically introduced uterine catheter, and blue dye flow out through the external opening of fistula was observed. At laparatomy fistula tract was completely excised along with the enclosing omentum. Postoperative recovery and follow-up were uneventful.

Discussion: Possible mechanisms of development of such a rare condition, and diagnostic and treatment options are discussed.
