Paramedian laparotomy: skin incision 3–5 cm off the midline

Patient positioning:

Supine position with slight hyperextension of the lumbar spine.

Surgical Technique of a Paramedian Laparotomy

A paramedian skin incision 3–5 cm off the midline and a paramedian incision of the anterior lamina of the rectus sheath is done. Dissect the tendinous intersections from the rectus sheath's anterior lamina until the rectus muscle's medial edge is seen. The rectus muscle is pulled to the lateral by a retractor. For an extraperitoneal approach, a paramedian incision of the fascia transversalis (below arcuate line) and posterior lamina of the rectus sheath (above arcuate line) without incision of the peritoneum is done. Blunt dissection develops the retropubic space, and the peritoneum is dissected to the medial, beginning from caudal to cranial.

Wound closure:

Close the rectus sheath in two layers (anterior and posterior sheath) with continuous running suture (monofilament, elastic, slowly absorbable, suture size USP 0 or 2-0), tissue bites of 5 mm and intersuture spacing of 4--5 mm are applied exclusively to the fascia (Deerenberg et al., 2015).
