Transvaginal small bowel evisceration after cervical loop electrosurgical excision procedure: a case report

Transvaginal small bowel evisceration is a life-threatening condition, which is usually seen in postmenopausal women with a history of gynecological surgery. Cervical loop electrosurgical excision procedure (LEEP) is widely used in the treatment of cervical intraepithelial neoplasia (CIN), and its surgical risk and postoperative complications are relatively low because of the simplicity of the operation. However, improper operation may result in perforation of the uterus, which can cause prolapse of the small bowel into the vagina. We here reported an extremely rare case of a young woman with transvaginal small bowel evisceration after cervical LEEP, achieving a good prognosis after the prolapsed bowel was reduced. The patient underwent cervical LEEP as a treatment for CIN III, but the LEEP resulted in a laceration of about 4.0 cm × 3.5 cm on the peritoneum of the uterovesical peritoneal reflection and a laceration of about 2.0 cm × 1.5 cm on the anterior wall of the cervical canal. Through the two lacerations, the pelvic cavity is connected to the vagina and the small intestine prolapsed into the vagina. Due to aggressive surgical intervention, the patient achieved a favorable prognosis after successfully reducing the prolapsed bowel.
