Inguinal hernia repair using TEP technique

1 cm long skin incision below the navel. Separate the adipose tissue with Langenbeck hooks and expose the fascia or anterior rectus sheath. This is incised with the scalpel on the side to be treated or, in the case of a bilateral hernia as in the example, on the side of the larger hernia, paramedian over a length of approximately 1 cm. The medial edge of the fascia is grasped with a sharp clamp. Using a Langenbeck hook, the medial rectus muscle is lifted anteriorly and laterally, thus exposing the posterior layer of the rectus sheath.

Tip: With a precisely median incision of the fascia, one enters directly into the abdomen and not into the rectus sheath. The fascia must then be closed again and incised further laterally!

A long preparation swab is advanced on the posterior leaf towards the symphysis and the preperitoneal space is bluntly dissected up to the retropubic area. Then, a 10mm trocar is inserted and CO2 gas is applied with pressures between 10 – 15 mmHg. The camera optics are introduced. Under visual control, a 5mm trocar is now inserted in the midline exactly between the navel and the symphysis.

Tip: Before inserting the 5mm trocar, pay attention to the epigastric vessels, which are usually visible. Use trocars with a locking mechanism, as they otherwise slip and significantly complicate the preparation!
