A female patient with a history of uterine surgery exhibiting a large uterine diverticulum complicated by abnormal uterine bleeding: a case report

The main symptoms of a previous Caesarean uterine scar diverticulum include abnormal uterine bleeding, chronic pelvic pain, and Caesarean scar pregnancy. Currently, laparoscopy combined with hysteroscopy provides a clear surgical field, allowing precise access to the uterine incision site under direct vision. This approach effectively reduces the risk of bladder damage while facilitating the repair of myometrial tissue. A 37-year-old woman who had undergone a caesarean section seven years earlier presented with vaginal bleeding that had persisted for more than a year. The diagnosis of a large uterine diverticulum was confirmed by magnetic resonance imaging and ultrasound. Laparoscopy combined with hysteroscopy was performed to repair the uterine scar diverticulum defect and recover the anatomy of the uterine isthmus. The surgery was successful, and the patient recovered well. At the three month follow-up, no interphase bleeding was observed. Laparoscopic folding and docking sutures combined with hysteroscopy are appropriate treatment options for correcting the uterine defect.
