Laparoscopic donor nephrectomy: short learning curve

Area of Science:

• Nephrology
• Minimally Invasive Surgery
• Transplant Surgery

Background:

• Laparoscopic donor nephrectomy (LDN) presents technical challenges for centers with low living donor volumes.
• The exact number of LDNs needed to master the procedure remains undefined.
• This study details the approach to LDN in a low-volume living donor transplant center.

Purpose of the Study:

• To evaluate the feasibility and safety of laparoscopic donor nephrectomy (LDN) at a low-volume transplant center.
• To assess the impact of a collaborative surgical approach on the learning curve and outcomes of LDN.
• To compare operative outcomes between a surgeon experienced in LDN and a trainee surgeon.

Main Methods:

• Retrospective review of donor records for two groups of six consecutive LDN cases each.
• Comparison of donor hospital stay, operative time, warm ischemia time, blood loss, and complications.
• Analysis of cases performed by an experienced surgeon versus a trainee surgeon under supervision.

Main Results:

• No conversions to open surgery or major/minor complications were reported in either group.
• Mean operative times were comparable between the experienced surgeon (267.5 min) and the trainee (300 min) (P = .28).
• Mean warm ischemia time was significantly shorter for the experienced surgeon (125 s) compared to the trainee (189.2 s) (P = .035).

Conclusions:

• Laparoscopic donor nephrectomy (LDN) can be safely and effectively performed in transplant centers with initial experience.
• A collaborative surgical model, involving an experienced LDN surgeon, is beneficial for minimizing donor risk.
• This approach aids in reducing the learning curve associated with LDN in lower-volume settings.
