Gibson Incision: Indications, Anatomy, and Surgical Steps

Urologic Indications

In urology, a Gibson incision is used for kidney transplantation or as an extraperitoneal approach to the distal ureter.

Gibson incision: the arc-shaped incision starts 2 cm medial to the anterior superior iliac spine and continues to the rectus sheath's lateral border (3 cm cranial to the inguinal ligament).

Patient positioning:

Supine position with slight hyperextension of the lumbar spine.

Surgical Technique of a Gibson Incision

• See fig. gibson incision for the skin incision.
• Divide the external oblique abdominal muscle in the direction of the muscle fibers.
• Transsect the internal oblique and transverse abdominal muscles at the lateral edge of the rectus sheath in the area of their aponeurosis. For a better approach, the lateral edge of the rectus muscle can be incised caudally.
• The inferior epigastric vessels are transected between ligatures.
• Push off the peritoneum cranially and medially with blunt dissection to expose the iliac vessels and ureter.

Wound closure:

Fascial closure in two layers with continuous running (monofilament, elastic, slowly absorbable, suture size USP 0 or 2-0) or interrupted sutures: the first suture reapproximates the internal oblique and transverse abdominal muscle, the second suture closures the external oblique abdominal muscle.
