Open Inguinal Hernia Repair — Key Steps and Mesh Fixation

Preoperative Landmarks

  • Right inguinal hernia discussed; landmarks include the anterior superior iliac spine (ASIS) at the hip and the pubic bone.

  • Incision planned between the landmark points; local anesthetic given in the area.

Exposure and Anatomical Planes

  • Incision through subcutaneous tissues to access the external oblique and its fascia.

  • External oblique opened sharply to enter the inguinal canal.

  • Ilioinguinal nerve preserved unless absolutely necessary to cut it.

  • Cord structures contain vas deferens, testicular vessels, cremasteric muscles, and associated vessels.

  • Penrose drain placed around the cord to maintain control and retraction.

Identification of the Hernia and Cord Structures

  • Fat attached to the cord dissected away to reveal the hernia sac.

  • Vas deferens and surrounding venous structures identified; genital branch of the genital femoral nerve runs through and is preserved.

  • Floor of the inguinal canal inspected; no direct defect observed.

  • Goal: free hernia sac into the preperitoneal space above the internal ring and reduce contents back to proper position.

Sac Management and Reduction

  • Hernia sac clamped and ligated, then divided.

  • Sac opened; contents (intestines/abdominal fat) can be felt as the sac is reduced.

  • Sac closed and reduced back under the muscle.

  • Any cord lipoma removed with electrocautery.

Mesh Preparation and Placement

  • Mesh used: Barred Soft Mesh (thin and flexible).

  • Mesh fixed to the pubic bone with absorbable sutures to secure anchoring.

  • A slit is made in the mesh to allow cord structures to pass through; slit is then closed.

  • Mesh is laid along and around the inguinal canal, with the lateral (top) portion tucked between internal and external oblique muscles to provide coverage.

  • Mesh fixed to the inguinal ligament at several points to secure it.

  • The cord is passed through the mesh slit and the slit is closed again.

  • If the mesh opening around the cord is a bit loose, an additional suture is placed to tighten it.

  • Mesh wraps around the cord to create a barrier while not constricting the cord structures.

Nerve Handling and Final Positioning

  • Ilioinguinal nerve repositioned under the mesh to avoid compression.

  • Mesh and nerve placement ensure the nerve lies in its normal course beneath the mesh.

  • External oblique fascia closed over nerve and mesh.

Wound Closure and Postoperative Care

  • Local anesthetic provided for postoperative pain control.

  • Penrose drain removed before closure.

  • Scarpa's fascia closed in a couple of locations to approximate deep tissues.

  • Subcutaneous tissues closed, followed by a running subcuticular skin closure.

  • Dermabond (medical superglue) applied as the primary dressing.

  • Final checks ensure tissue layers are closed and clean before leaving the operating room.
