Laparoscopic Transabdominal Cerclage for Cervical Incompetence: A Feasible and Effective Treatment in 10 Steps

Abstract

To demonstrate the surgical technique of laparoscopic cerclage (LAC) in nonpregnant women with a clinical diagnosis of cervical incompetence. In this video, the authors describe the complete procedure in 10 steps to standardize and facilitate the comprehension and performance of the procedure in a simple and safe way. Step-by-step video demonstration of the surgical technique. Private hospital in Curitiba, Paraná, Brazil. The patient was 32 years old (gravidity and parity, G3A3; late progressive miscarriage), had no comorbidities, and had a radiologic diagnosis of cervical incompetence. The main steps of LAC are described in detail. A complete laparoscopic approach was performed. Under general anesthesia, the patient was placed in the 0-degree supine decubitus position with arms alongside her body. The operative setup included a 15-mm Hg pneumoperitoneum created using the closed Veress technique and 4 trocars: a 10-mm trocar at the umbilicus for a 0-degree laparoscope; a 5-mm trocar in the right iliac fossa; a 5-mm trocar in the left iliac fossa; and a 5-mm trocar in the suprapubic area. After systematic exploration of the pelvic and abdominal cavities, the procedure began. Step 1 involved identification of anatomic key landmarks and exposure of the operation field. Step 2 involved opening of the anterior peritoneum. The anterior peritoneal reflection was opened over the peritoneum uterovesicalis and then extended laterally until the uterine artery could be clearly identified on both sides. Step 3 involved dissection of the avascular space on each side of the uterus. The vesical-cervical avascular space was created, and the bladder was pushed down, away from the isthmus area. Step 4 involved preparation for a perfect stitch placement. A 5-mm Mersilene suture (Ethicon, Somerville, NJ) with a straight needle was introduced by a suprapubic trocar into the abdominal cavity before a complete identification of uterine vessels at both the sides using atraumatic graspers. Step 5 involved identification of the perfect space in the posterior aspect for Mersilene suture placement. Step 6 was to make a perfect anterior stitch. For this, the needle was grasped at the proximal portion in a 90-degree angle. In posterior position and when helped by a cranial and posterior uterine mobilization, the needle passed through the right, broad ligament in the avascular space created on the anterior leaf and medially from the uterine artery until the tip of the needle was seen on the posterior face above the uterosacral ligament. All steps were possible by synchronic uterine mobilization. Step 7 was to make a perfect posterior stitch. The procedure was then repeated contralaterally following the same anatomic and technical precepts but from posteriorly to anteriorly. Step 8 involved correct positioning and orientation of the Mersilene suture far away from the ureter and medial to the uterine arteries 2 cm over the uterosacral ligaments. Step 9 involved fixation of the Mersilene suture with an adequate blocking sequence. Step 10 involved fixation of the Mersilene suture and reperitonealization. The tape was knotted with an adequate blocking intracorporeal suturing sequence at the cervicoisthmic junction, and a Monocryl 2-0 stitch (Ethicon, Somerville, NJ) was made to fix the knot and left it horizontally. Finally, the procedure was ended with anterior reperitonealization, covering all the plica uterovesicalis and mesh, leaving it completely extraperitoneal. The surgery ended without any intraoperative complications and within 30 minutes. Patient was discharged on the first day postoperatively and became pregnant 6 months after surgery, with a C-section delivery of a healthy term newborn at 39 weeks of gestational age. LAC in nonpregnant women with a diagnosis of cervical incompetence is safe and feasible in experienced hands, adding all the intrinsic advantages of minimally invasive surgery and providing better obstetric outcomes. In this patient, the procedure was performed without any intra- or postoperative complications, and the patient had an uneventful term pregnancy in the follow-up period. We must remember that adequate standardization of surgical procedures will help reduce the learning curve.
