Scar-free gallbladder removal is being offered to all suitable patients by a team of surgeons from Mt. Sinai Hospital in New York who have pioneered the technique. They are also extending this new type of surgical procedure to other operations in the abdomen.
They reported on their updated findings today at the 2010 Annual Clinical Congress of the American College of Surgeons.
The procedure is known as laparoendoscopic single-site surgery, or LESS. It marries laparoscopy, known commonly as minimally invasive surgery that requires small incisions in the abdomen to insert instruments, with endoscopy, a probe with a camera that lets the surgeon see inside the abdomen. Laparoscopy is an alternative to an open operation, which involves a large incision to actually open the surgical site.
The LESS procedure goes one better than minimally invasive surgery, according to study coauthor Edward Chin, MD, FACS, a general surgeon at Mt. Sinai Medical Center in New York. "Minimally invasive gallbladder surgery requires the surgeon to make four small incisions in a half-moon pattern in the abdomen, but the LESS procedure requires one incision made through the navel. Moreover, laparoscopy leaves behind four visible, small scars in the abdomen following a procedure. LESS leaves virtually none," he said.
The LESS approach to gallbladder surgery is not for everyone, Dr. Chin cautioned. Patients who need emergency surgery or who have had previous abdominal operations that built up scar tissue are probably not suitable candidates. "Those two populations aside, we try to offer this technique to everyone who is coming in for elective laparoscopic gallbladder surgery," he explained.
