Inguinal Hernia Repair by TEP - general and visceral surgery

1 cm subumbilical skin incision Split the fatty tissue with Langenbeck retractors and expose the fascia/anterior rectus sheath. About 1 cm paramedian scalpel incision on the side of the hernia. Pull the medial flap of the fascia anteriad with a sharp clamp. Slip the Langenbeck retractor below the rectus muscle and lift it anteriad.

Tip: If the fascia is incised precisely in the midline, this will open the abdominal cavity and not the rectus sheath. In this case, close the fascia and incise more laterally.

With a long peanut sponge on the posterior lamina of the rectus sheath, bluntly dissect the preperitoneal space down retrosymphysially. Follow this with blunt insertion of the 10 mm trocar and then gas inflation at a pressure of 10 – 15 mmHg. Insert the laparoscope with the camera Under visual control insert a 5 mm trocar in the median plane exactly halfway between the umbilicus and pubic symphysis

Tip: Note the epigastric vessels regularly seen here, before inserting the 5 mm trocar. Use trocars with a locking mechanism since otherwise they will slip and massively hinder any preparation!

Dissect the preperitoneal space, primarily with the scissors, through the 5 mm trocar. Starting retrosymphysially, clear the tissue in one anteroposterior sweep from the posterior aspect of the pubic symphysis down to the bladder. Small vessels traversing the field can be coagulated.

Follow this by bluntly dissecting the lateral space in the same way until the lateral margin of the rectus sheath is seen. Transect it in small steps with the scissors up to the plane of the superior anterior iliac spine. Under visual control, insert the second 5 mm trocar about 2 cm medial to the iliac spine.

Tip: Sharply transect the lateral margin of the rectus sheath as far anterior as possible since otherwise this would open up the abdominal cavity!
