Remnant Functioning Cervical Tissue After Laparoscopic Removal of Cavitated Noncommunicating Rudimentary Uterine Horn

Abstract

Cavitated noncommunicating rudimentary uterine horn is managed via surgical removal. During the past 20 years this has been performed primarily via laparoscopy. At our multidisciplinary specialized center, this condition has been treated in 29 patients over 10 years. Three patients had pelvic pain and recurrent symptoms of menstrual obstruction at 2, 5, and 6 years after the initial operation. Magnetic resonance imaging revealed blood-filled pelvic masses at the site of the previous procedures. After laparoscopic removal of these masses, histologic analysis confirmed the presence of remnant functioning cervical tissue. This is the first report of long-term follow-up of patients with a history of obstructed rudimentary uterine horn to demonstrate that complications can occur several years after such operations. It is essential that any reports of recurrent pain should be considered seriously and investigated.
