Lecture Handout Prepared from the Teaching Session by: Dr. R. K. Mishra

SUMMARY

This lecture provides a comprehensive overview of the laparoscopic pectopexy procedure for the surgical management of uterine prolapse. Dr. R. K. Mishra details the operative technique, emphasizing the use of the pectineal (Cooper's) ligament as the anchoring point for a synthetic mesh to support the uterus. The procedure is presented as a viable alternative to sacrocolpopexy, with advantages in ease of suturing. The lecture covers key steps including patient positioning, port placement, pneumoperitoneum creation, peritoneal dissection to expose the Cooper's ligaments, mesh preparation and fixation, and peritoneal closure. Emphasis is placed on meticulous dissection, secure suturing with non-absorbable material, and the principles of creating a tension-free yet supportive repair.

INTRODUCTION

Uterine prolapse is a common and distressing condition affecting a significant number of women, resulting from the weakening of the pelvic floor muscles and ligaments that support the pelvic organs. While hysterectomy has traditionally been a definitive treatment, uterus-preserving surgical techniques are increasingly favored, particularly in women who wish to retain their uterus. Laparoscopic pectopexy has emerged as an effective surgical option. This procedure involves suspending the uterus and cervix using a synthetic mesh, which is anchored superiorly to the robust pectineal (Cooper's) ligaments bilaterally. Compared to the technically demanding sacrocolpopexy, pectopexy offers a more accessible surgical field for suturing and avoids dissection in the sacral promontory region, thereby mitigating the risk to major vessels and nerves in that area. This lecture will detail the standardized technique for performing laparoscopic pectopexy.

LEARNING OBJECTIVES

To understand the indications and anatomical principles of laparoscopic pectopexy.
To learn the step-by-step surgical technique, including port placement, peritoneal dissection, and identification of the Cooper's ligament.
To master the methods of mesh preparation, suturing to the cervix, and fixation to the pectineal ligaments.

CORE CONTENT

1. Patient Preparation and Port Placement

Positioning: The patient is placed in a steep Trendelenburg position to displace the bowel and provide optimal visualization of the pelvic cavity. The uterus is manipulated into a retroverted position to facilitate anterior dissection.
Pneumoperitoneum: A Veress needle is introduced through an infraumbilical stab incision. Correct intraperitoneal placement is confirmed using the hanging drop test and irrigation/aspiration test. The abdomen is insufflated to a preset pressure of 15 mmHg with an initial flow rate of 1 L/min.
Port Placement:
- An 11 mm optical port is placed at the umbilicus.
- Two 5 mm working ports are placed ipsilaterally.
- One 5 mm working port is placed contralaterally. This configuration is similar to that used for a standard laparoscopic hysterectomy.

2. Peritoneal Dissection and Exposure of Cooper's Ligament

Initial Incision: The dissection begins by incising the anterior leaf of the broad ligament. This incision is extended across the vesicouterine fold and continues on the contralateral side. The incision should be made parallel to the round ligament, extending laterally towards the deep inguinal ring.
Bladder Dissection: The bladder is meticulously dissected and mobilized inferiorly off the anterior cervix and upper vagina. This step is crucial for adequate mesh placement and concurrent correction of a mild cystocele. A blunt dissector, such as a peanut pledget, is effective for creating this plane.
Accessing the Space of Retzius: To expose the Cooper's ligament, a transabdominal pre-peritoneal approach is utilized. The medial umbilical ligament is identified and retracted medially. Blunt dissection is then performed lateral to this ligament, entering the Space of Retzius. This maneuver avoids the bladder, which lies between the two medial umbilical ligaments.
Identification of Cooper's Ligament: The Cooper's (pectineal) ligament is identified as a pearly-white, fibrous structure. It is often referred to as a "lighthouse" due to its bright, reflective appearance under laparoscopic light. This process is repeated on both the right and left sides.

3. Mesh Preparation and Fixation

Mesh Preparation: A standard polypropylene mesh, approximately 6 cm x 20 cm, is used. It is trimmed into a 'T' shape. The long, vertical limb of the 'T' maintains a width of 6 cm, while the horizontal crosspiece is divided into two 'T-limbs,' each 3 cm in width.
Mesh Introduction: The prepared mesh is introduced into the abdominal cavity through the 11 mm optical port.
Cervical Fixation: The wider, vertical limb of the mesh is attached to the anterior aspect of the cervix and the vaginal fascia. This is performed using multiple interrupted, non-absorbable sutures (e.g., Dacron, Ethibond, or silk). It is imperative to take full-thickness bites through the cervical fascia to ensure a strong, durable repair. A surgeon's knot is typically used, with the option of a tumble square knot if slippage is a concern.
Cooper's Ligament Fixation: The two 'T-limbs' of the mesh are extended laterally to reach the previously exposed Cooper's ligaments. An assistant maintains the uterus at the desired level of elevation, ensuring the mesh is taut but not under excessive tension. The limbs are fixed to the Cooper's ligaments using either titanium tacks (e.g., ProTack) or non-absorbable sutures. Typically, 2-4 tacks are applied on each side.

4. Peritoneal Closure

Re-peritonealization: The final step is to completely cover the mesh by closing the peritoneal flaps. This is achieved using a continuous absorbable suture (e.g., Vicryl).
Suturing Technique: The closure begins laterally. A self-locking knot (e.g., Dandy jamming knot) can be used to start the suture line. The round ligament may be incorporated into the initial bites to aid in its plication. A locking stitch may be placed in the center to prevent suture loosening. The closure continues until the entire mesh is extraperitonealized, minimizing the risk of future bowel adhesion. The final knot is secured using an Aberdeen termination (loop-within-loop technique).
Final Inspection: Upon completion, the anatomical correction of the prolapse is immediately visible.

SURGICAL PEARLS

Dissection: Keeping the peritoneum under constant tension during dissection creates a clean, avascular plane and minimizes bleeding.
Suturing to Cervix: Ensure deep bites into the dense cervical fascia, not just superficial tissue. The movement of the entire uterus when tugging on the suture confirms a secure bite. Use multiple interrupted sutures for redundancy; if one fails, others will maintain the repair.
Suturing Angle: While ipsilateral port suturing is possible, it involves a narrow manipulation angle (approx. 30°), which can be challenging. Using the contralateral port for suturing often provides a more ergonomic angle.
Mesh Tension: The goal is a tension-free repair. The mesh should be snug enough to provide support but not so tight as to cause tissue erosion or ischemic changes. The assistant must hold the uterus at the final desired position while the mesh is being fixed to the Cooper's ligaments.
Tacker Application: When using tacks to fix the mesh to the Cooper's ligament, the tacker should be applied as perpendicularly as possible to the tissue to ensure secure deployment and fixation.

COMPLICATIONS AND THEIR MANAGEMENT

Intraoperative:
- Bleeding: Can occur during peritoneal dissection. Minimized by staying in the correct avascular planes. Bleeding from the inferior epigastric vessels can occur if dissection extends too far laterally during peritoneal closure; these vessels should be identified and avoided.
- Bladder Injury: A risk during the initial bladder mobilization. Careful, sharp, and blunt dissection over the colpotomizer tip helps prevent this.

MEDICOLEGAL AND PATIENT SELECTION CONSIDERATIONS

This procedure is an option for patients with uterine prolapse who wish to preserve their uterus.
The use of synthetic mesh carries inherent risks, including mesh erosion, infection, and chronic pain, which must be part of the informed consent process.
Surgical success is highly dependent on secure fixation. Inadequate suturing or tacking can lead to early recurrence, negating the benefit of the surgery. Taking a sufficient number of secure bites is a critical risk-mitigation strategy.

SUMMARY AND TAKE-HOME MESSAGES

Laparoscopic pectopexy is an effective uterus-preserving procedure for uterine prolapse, utilizing the Cooper's ligaments for durable apical support.
The key to the procedure is a TAPP-like pre-peritoneal dissection to safely expose the Cooper's ligaments, avoiding the bladder and major vessels.
Secure fixation of the mesh to the cervix with multiple non-absorbable sutures and to the Cooper's ligaments with tacks or sutures is paramount for long-term success.
Complete re-peritonealization of the mesh is a mandatory final step to prevent visceral adhesions and related complications.
