Uterocutaneous fistula (UCF) is a very clinical entity that occurs mostly following surgical injuries. We present a case of a 35-year-old nulliparous woman who developed UCF following openabdominal myomectomy. She was managed successfully using laparotomy with fistula tract excision and repair. Her symptoms resolved spontaneously after surgery,

Myomectomy is a procedure for the removal of uterine fibroids, it is more commonly carried out in women who desire to retain their reproductive function, vis-a-vis, childbearing. Although it is a common surgical procedure in our environment, it sometimes results in some complications, such as excessive bleeding, surgical site infection, inadvertent injury to contiguous structures, adhesion formation, wound dehiscence, enterocutaneous fistula, and rarely, uterocutaneous fistula (UCF).,, Development of these complications sometimes depends on the uterine size prior to surgery, other associated comorbidities, such as obesity, history of prior abdominal surgeries, skill of the surgeon, and among other risks.
A fistula is generally defined as an abnormal communication between two epithelial surfaces. There are several types of fistulas encountered in obstetrics and gynecological practice, ranging from ureterovaginal, vesicovaginal (such as juxta-urethral, mid-vaginal, juxta-cervical), vesicocervical or vesicouterine (including Youssef syndrome), rectovaginal, and very rarely UCF.,, Uterine fistulas usually involve the cervix, bladder, or the rectum (uterocervical, vesicouterine, or uterocolonic) and occasionally, the skin., The etiology of these fistulas includes direct causes from obstetric injuries, following improper use of drains, incomplete closure of incisions, postoperative injuries, multiple abdominal surgeries, iatrogenic injury during difficult cesarean sections, following surgical techniques for postpartum hemorrhage, gynecological malignancies, genital tract tuberculosis, major gynecological surgeries, and postoperative wound infection or after septic abortion.,,,,
There is no standardized protocol or guideline for the management of UCF owing to its rarity. However, many imaging modalities have been utilized in the diagnosis and treatment of women with UCF.,, These imaging techniques such as ultrasonography, fistulogram, magnetic resonance imaging, and computed tomography scan have found various use in the management of UCF.,, Currently, other modalities of management including exploratory laparotomy, laparoscopic and hysteroscopic excision, and repair the fistula tract have been utilized.,,, Medical management using gonadotropin-releasing hormone agonists to induce pseudomenopause to allow for proper evaluation and management has also been utilized.,,
A 35-year-old nulliparous woman was referred to our facility in 2019 with an inability to conceive and cyclical bleeding from abdominal scar of 8 years' duration. She was diagnosed with multiple uterine fibroids in 2011 following which she had open abdominal myomectomy at the referring facility. Her surgery was complicated by surgical site infection and wound breakdown, during which she had parenteral antibiotics and secondary wound closure thereafter. Two weeks later, her menses spontaneously returned partly through the vagina and partly through the surgical site. She was commenced on subcutaneous 3.6 mg of Goserelin monthly for 6 months, but the symptom returned following return of her menses. Physical examination revealed a hypertrophied midline subumbilical midline scar with two dimples and tenderness along the lower half of the scar. Pelvic ultrasonography revealed a uterus with a fundal defect and anterior surface adhered to the anterior abdominal wall with probe tenderness along the lower half of the scar, ultrasonography-guided uterine probe transcervically with an intra-uterine insemination catheter revealed probe beyond the uterus protruding through the fistulous tract on the anterior abdominal wall. A hysterosalpingography was done, during which an injected contrast was seen flowing through the abdominal incision site with no evidence of spill of filling of the Fallopian tubes.
She also had a hysteroscopy done which revealed a 2 cm defect at the fundal region of the uterus, tubal ostia were not visualized. She subsequently had exploratory laparotomy with excision and repair of the fistula. She had a repeat HSG and hysteroscopy subsequently which revealed no defect. Her menstrual flow restarted vaginally with no flow through the surgical site.
A case of 35-year-old nulliparous woman with UCF has been presented. Although one of the very rare types of fistulae, with few cases reported globally, UFC is most times misdiagnosed as endometriosis, wound infection, or even as an abscess. It is because of this rare occurrence that its approach to diagnosis and treatment has not been standardized.,,
Most cases of UCF reported are secondary to multiple abdominal surgeries, especially myomectomy and cesarean sections., However, other etiologies include UCF occurring post irradiation of the genital tract, tuberculosis, or even postB-lynch suturing for postpartum hemorrhage because of extensive uterine necrosis, postabdominal pregnancy, migration of intrauterine device, and secondary to congenital anomaly of the genital tract., Our patient was presented following abdominal myomectomy and failed medical therapy.
No standardized management approach exists currently, because of its rarity, few cases have been managed using medical therapy either to induce pseudomenopause or to relieve pain arising from other complications such as endometriosis., Majority of UCF are managed using surgical approach either laparotomy or laparoscopy., The extent of the surgery also depends on patients' desire and expertise of the surgeon., Our patient had laparotomy with fistula tract excision and repair. She was not fit for medical therapy because she presented after 8 years of the previous surgery, when the fistula tract had already undergone fibrosis and may not respond to medical treatment.
UCF is a very rare complication of abdominal myomectomies, with different modalities of management. It can be prevented by meticulous surgical technique, use of potent antibiotics to prevent surgical site infection, and optimizing the patient prior to surgery.
