Abstract
Laparoscopic peritoneal dialysis catheter insertion is an established method for peritoneal dialysis catheter placement. One critical aspect of this procedure is rectus sheath tunneling. Proper peritoneal dialysis catheter incorporation within the abdominal wall is important for reducing pericatheter leaks and for proper peritoneal dialysis functioning. Particularly, accurate positioning of the internal cuff within the rectus muscle sheath is crucial to prevent potential dialysate fluid leakage. In the present report, we describe the utilization of intraoperative ultrasound as a valuable tool for determining the ideal location of the internal cuff and assessing the course of the inferior epigastric artery during rectus sheath tunneling. This technique aims to optimize the position of the internal cuff and minimize complications such as vessel injury and pericatheter leaks. Furthermore, we demonstrate that post-catheter insertion, ultrasound imaging offers valuable insights into evaluating the appropriate placement of the internal cuff, external subcutaneous cuff, and potential bleeding within the abdominal wall.
