Dissecting Technique Open Surgery

The dissecting technique is commonly utilized by general surgeons and involves placing the catheter by minilaparotomy under general anesthesia (11). The layers of the abdominal wall are dissected under direct vision. The parietal peritoneum is identified and incised. The catheter is advanced into the peritoneal cavity by feel until the deep cuff is within the rectus muscle. The cuff is then secured in the rectus muscle by sutures placed at the peritoneal entry site and at the outer rectus sheath.
