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.
