Vaginal Approach to Cesarean Section Scar Pregnancies: A Standardized Ten-step Surgical Procedure.

Abstract

OBJECTIVE: To show a 10-step standardized vaginal surgical technique to treat first-trimester cesarean section scar pregnancies. DESIGN: A video article with a stepwise demonstration captured in an operation room of a tertiary medical center of a low-income country (Bolivia). SETTING: Cesarean section scar pregnancies have a wide variety of management options. We present a vaginal surgical approach that has been developed by our group with no observed complications in 6 consecutive cases at the time of this publication. INTERVENTIONS: A 10-step technique: (1) patient positioning, (2) cervical exposure and traction, (3) cervical infiltration with vasoconstrictor solution, (4) anterior mucosal incision and dissection of vesicovaginal space, (5) identification of vascular pedicle and ligation, (6) cold-knife isthmocele incision and ectopic pregnancy evacuation, (7) uterine cavity curettage, (8) hysterorrhaphy with interrupted suture, (9) cystoscopy, and (10) vaginal mucosa closure with running suture. We have used this technique in 6 consecutive patients. Operating time ranged between 20 and 25 minutes. All patients were discharged in postoperative day 1. CONCLUSION: We prefer surgical options for these patients because it provides both a complete removal of the ectopic pregnancy and repair of the isthmocele. A vaginal approach to such cases has proven to be a safe, simple, and fully reproductible technique. We find it applicable for any patient with this pathology but especially suitable for low-resource or somehow financially challenged hospitals.
