NYP -- In April of last year, surgeons at NewYork-Presbyterian Hospital/Columbia University Medical Center made headlines by removing a women’s gallbladder through her uterus using a flexible endoscope, aided by several external incisions for added visibility. Now, they have performed the same procedure without a single external incision in what surgeons report may be the first surgery of its kind in the United States. Led by Dr. Marc Bessler the procedure is offered as part of an ongoing clinical research trial and could prove to have advantages over traditional endoscopic surgery, including reduced pain, quicker recovery time and absence of visible scarring.
