Laparoscopic v laparoscopy-assisted donor nephrectomy in the porcine model

Area of Science:

• Surgical Innovation
• Minimally Invasive Surgery
• Transplantation Research

Background:

• Laparoscopic donor nephrectomy is a standard procedure in porcine models.
• Comparing live laparoscopic (LAP) and laparoscopy-assisted (LAP-A) donor nephrectomy is crucial for optimizing surgical techniques.

Purpose of the Study:

• To compare intraoperative variables between live laparoscopic (LAP) and laparoscopy-assisted (LAP-A) donor nephrectomy.
• To evaluate the efficiency and outcomes of LAP-A donor nephrectomy using the Pneumosleeve.

Main Methods:

• Eight domestic pigs were divided into two groups (N=4 each).
• One group underwent traditional laparoscopic donor nephrectomy (LAP).
• The other group underwent laparoscopy-assisted donor nephrectomy (LAP-A) using the Pneumosleeve, followed by heterotopic autotransplantation.

Main Results:

• No significant differences were observed in vessel length, ureteral length, or postoperative urine output between the groups.
• Operating room time was significantly shorter in the LAP-A group (75.8+/-10.3 min) compared to the LAP group (108+/-12 min) (P = 0.0065).
• Warm ischemic time tended to be lower in the LAP-A group (70+/-3.0 sec) versus the LAP group (135+/-57 sec) (P = 0.059).
• Graft survival rates were identical in both groups.

Conclusions:

• Laparoscopy-assisted live donor nephrectomy, utilizing the Pneumosleeve, effectively shortens operative time.
• This technique demonstrates comparable graft survival to traditional laparoscopy in the domestic swine model.
• The LAP-A approach offers a more time-efficient method for live donor nephrectomy without compromising graft outcomes.
