Scarless Surgery Utilizes “Natural Orifices”

It has the ring of a “Ripley’s Believe It or Not” story — gallbladders are surgically removed through the mouth… a kidney is taken out via the vagina… a colon is extracted from the rectum. Yet it’s true — these and other natural orifice surgeries have been successfully performed at academic medical centers around the country, including Johns Hopkins University, University of California, San Diego Medical Center and New York Presbyterian Hospital-Columbia University Medical Center, and you’ll undoubtedly be hearing more about such procedures in the future.

These groundbreaking procedures are the latest twist in minimally invasive surgery, which reduces pain, scarring and recovery time. I spoke with Marc Bessler, MD, one of the surgeons who performed the first transvaginal gallbladder removal. Dr. Bessler is director of both the Minimal Access Surgery Center and the Center for Metabolic and Weight Loss Surgery at New York-Presbyterian Hospital/Columbia University Medical Center.

USING “NATURAL OPENINGS”

The trend toward less invasive procedures was evident in the late 1980s with laparoscopic surgery — where doctors thread narrow instruments and cameras into the body, their actions guided by video images displayed on monitors in the operating room. Now surgeons have pushed the envelope even further with natural orifice procedures. Dr. Bessler informed me that natural orifice surgery is still in an early and experimental stage, yet it shows great promise for the future. These revolutionary new procedures are collectively referred to as Natural Orifice Transluminal Endoscopic Surgery (NOTES), or — less scientifically — as “scarless” surgeries.

Dr. Bessler called that first gallbladder removal that he performed through the vagina a “hybrid” operation, since for safety’s sake he also made several small laparoscopic cuts in the patient’s belly. While many natural orifice procedures are still performed this way, Dr. Bessler and a small cadre of fellow pioneer surgeons have now started to do some surgeries through natural body openings without making any external cuts at all.

AVAILABLE PROCEDURES

The most common openings used are the vagina, mouth and anus. In addition to gallbladder operations, other procedures performed through these new routes include sleeve gastrectomy to treat obesity, tubal ligation, kidney and appendix removal, tumor removal and diagnostic evaluations.

Dr. Bessler cautions that while the cosmetic results of natural orifice surgery are a significant plus, since the scars are hidden internally, surgery is still surgery. Whether a surgeon enters the body through the vagina, mouth or rectum, he/she must still cut through internal tissue walls to reach and operate on organs. There will still be pain and recovery time, albeit at the less severe level of laparoscopic surgery rather than that of traditional open procedures. “We hope and many believe that we can achieve pain-free and recovery-free surgery using NOTES,” said Dr. Bessler.

Be aware, however, that although natural orifice procedures have enormous potential, the field is in its infancy and further trials are still being conducted. Dr. Bessler emphasizes that he and other surgeons are in the process of researching, developing, testing and perfecting these new surgical techniques. Far from being widely available, natural orifice procedures are primarily performed on an experimental basis at major surgical centers, and although this is likely to change in the future, few surgeons at present possess the skills and training to undertake them.
