BALTIMORE—In the largest study of its kind, living donors who had a kidney removed through a single port in the navel report higher satisfaction in several key categories, compared to donors who underwent traditional multiple-port laparoscopic removal.
The new technique has been described as virtually scarless, because nearly the entire incision, once healed, is hidden within the belly button. Researchers at the University of Maryland School of Medicine in Baltimore found the belly button group had significantly improved satisfaction with the cosmetic outcome and the overall donation process. Additionally, the new technique was associated with fewer limitations in bending, kneeling or stooping following surgery, and slightly less pain after surgery, compared to the multi-port approach. At the same time, the study found the two procedures equally safe. The results are published online in the Annals of Surgery.
“Everything we do in organ transplantation is based on the generosity of organ donors,” saidlead author Rolf Barth, MD, associate professor of surgery at the University of Maryland School of Medicine and transplant surgeon at University of Maryland Medical Center. “If we as surgeons can safely improve the donation process for our living donors by perfecting less-invasive surgical options, we should embrace these new approaches.”
Single-port donor nephrectomy, also known as laparoendoscopic single-site (LESS) surgery, has been the standard of care for living kidney donors at the University of Maryland Medical Center (UMMC) for the past three years; however, no objective data previously existed to compare the single-port with the multiple-port laparoscopic techniques. UMMC is only the third hospital in the country to consistently use this surgical approach on living donors and, to date, has employed the single-port technique in 215 donors.
