Advances Reported in Less Invasive Surgery

SAN DIEGO, Aug. 2 (UPI) — U.S. surgeons are finding ways to make already less invasive surgery even less invasive, resulting in a more rapid recovery and reduced pain.

Surgeons at the University of California, San Diego, School of Medicine have reduced already minimally-invasive surgery for cancer patients requiring only six small incisions to a single small incision.


The procedure Laparo-Endoscopic Single-Site Surgery can be used to remove a kidney — partially or totally — or to remove tumors and blood clots from the main kidney vein.

“For advanced as well as localized kidney cancer, our surgical team has been able to reduce and consolidate the number of incisions to one port hidden in the belly button,” Dr. Ithaar Derweesh, a professor of surgery, says in a statement. “With one small opening to deploy instruments and remove diseased tissue, patients benefit from fewer complications, minimal opiate-requirements, preserved quality of life and excellent short term outcomes.”

Derweesh says studies involved a small number of patients and larger studies are needed, but generally less incisions are linked to a more rapid recovery and reduced pain.

“What we are seeing is that techniques such as these are more technically rigorous for the surgeon but infinitely better for patients,” Derweesh says. “As our experience grows with single-port laparoscopy, we are committed to perfecting the operating tools and training new surgeons in these emerging techniques.”

The pilot studies are reported in the journals Central Urology and Diagnostic and Therapeutic Endoscopy.
