This video demonstrates Suprapubic Incisional Hernia Repair by Mishra's Knot and Mobilization of the Urinary Bladder Performed by Dr. R.K. Mishra at World Laparoscopy Hospital. The suprapubic hernia is the term to describe ventral hernias located less than 4 cm above the pubic arch in the midline. Hernias with an upper margin above the arcuate line encounter technical difficulties, and the differences in repair methods forced us to define them as large suprapubic hernias. Laparoscopic repair of large suprapubic hernias can be considered the first option in treatment. The low recurrence rates reported in the literature and the lack of recurrence, as observed in our study, support this view.

Suprapubic incisional hernia is a challenging form of ventral hernia that occurs following lower abdominal or pelvic surgeries such as cesarean section, hysterectomy, or prostate surgery. The anatomical proximity of the hernia defect to the urinary bladder, pubic symphysis, and neurovascular structures makes surgical repair technically demanding. Modern laparoscopic techniques, combined with innovative suturing methods such as Mishra’s Knot, have significantly improved outcomes in these complex hernias.

Anatomical Challenges of Suprapubic Incisional Hernia

The suprapubic region lacks adequate posterior rectus sheath support below the arcuate line. Additionally, the urinary bladder often adheres to the previous surgical scar, increasing the risk of bladder injury during dissection. Secure mesh fixation near the pubic bone is difficult due to limited space and the risk of chronic pain if tackers are improperly placed. These factors necessitate meticulous dissection and advanced suturing techniques.

Importance of Urinary Bladder Mobilization

Adequate mobilization of the urinary bladder is a critical step in suprapubic incisional hernia repair. The bladder must be gently dissected and pushed inferiorly to expose sufficient healthy tissue for mesh overlap. This step:

Prevents accidental bladder injury

Allows proper mesh placement with adequate inferior overlap

Reduces the risk of hernia recurrence

Enhances long-term surgical outcomes

Sharp and blunt dissection under direct laparoscopic vision ensures safe separation of the bladder from the abdominal wall.

Role of Mishra’s Knot in Hernia Repair

Mishra’s Knot, developed by Dr. R.K. Mishra, is a reliable extracorporeal knotting technique widely used in laparoscopic surgery. In suprapubic hernia repair, this knot offers several advantages:

Strong and secure mesh fixation

Precise control in difficult-to-access areas

Reduced dependence on tackers near the pubic bone

Lower risk of nerve injury and chronic postoperative pain

Mishra’s Knot ensures firm anchorage of the mesh even in areas where conventional fixation methods are limited.

Surgical Technique Overview

Patient Positioning and Port Placement: The patient is placed in a supine position with appropriate port placement to allow ergonomic access to the suprapubic region.

Adhesiolysis: Careful adhesiolysis is performed to free the hernia sac and surrounding structures.

Bladder Mobilization: The urinary bladder is gently dissected and mobilized inferiorly to create adequate space for mesh placement.

Mesh Placement: A suitably sized mesh is positioned with sufficient overlap beyond the hernia defect.

Mesh Fixation Using Mishra’s Knot: The mesh is securely fixed using Mishra’s Knot, ensuring tension-free repair and optimal stability.

Final Inspection: Hemostasis is confirmed, and the integrity of the repair is assessed.

Advantages of Laparoscopic Repair with Mishra’s Knot

Minimally invasive approach with reduced postoperative pain

Enhanced visualization of pelvic anatomy

Strong and durable mesh fixation

Lower recurrence rates

Faster recovery and shorter hospital stay

Postoperative Care and Outcomes

Patients typically experience minimal discomfort and can resume normal activities early. Proper bladder mobilization and secure mesh fixation significantly reduce complications such as recurrence, chronic pain, and urinary symptoms. Long-term outcomes are excellent when the procedure is performed by experienced laparoscopic surgeons.

Conclusion

Suprapubic incisional hernia repair requires a high level of surgical expertise due to complex anatomy and proximity to vital structures. The combination of urinary bladder mobilization and mesh fixation using Mishra’s Knot offers a safe, effective, and reproducible solution. This advanced laparoscopic technique, pioneered and taught by Dr. R.K. Mishra, represents a significant advancement in the management of complex ventral hernias.
