Dr. Dennis Begoswas heavily involved in teaching other surgeons how to perform laparoscopic colon surgery when it was first making waves back in 1997. Dr. Begos began teaching his peers through courses at the Cleveland Clinic, Brown University, and other local hospital systems.
In the past, open surgery via a sizeable abdominal incision was the only way to access the colon and remove the diseased or infested area of the intestine. Dr. Dennis Begos was the first physician in the Boston area (likely all of Massachusetts) to perform laparoscopic colectomy, which is now a standard procedure.
Instead of a full abdominal incision, the minimally invasive procedure, Laparoscopic Colectomy, is performed directly through several tiny portal incisions in the abdomen and the navel. A small video camera is placed through one of the ports, and laparoscopic surgical tools are simultaneously used through the other tiny incisions. On a monitor, the surgeon can see the colon and surrounding areas to precisely retrieve the colon and pull it through one of the abdominal incisions. This allows the surgeon to operate on it outside of the body. The colon will easily be reinserted back into the body once the repairs have been made.
Dr. Dennis Begos training programs were detailed in several published papers, including Abstract, Journal of the Society of Laparoendoscopic Surgeons1andSurgical Endoscopy, Epub2. From 2016 to 2017 Dennis Begos, MD was heavily involved in hospital leadership, being the president of the medical staff at Winchester Hospital. Dr. Begos did his general surgery residency at Yale University (1990-96), where he was honorably named Chief Resident in his last year. Dr. Begos then went on to do a one-year fellowship in colon and rectal surgery at the Cleveland Clinic (1996-97), where he trained with some of the world’s foremost experts in the field.
Along with his numerous leadership positions, in the past, Dr. Dennis Begos has been instrumental as an Assistant Professor of Surgery at Tufts University School of Medicine. Dr. Begos is also very involved in the community as an outreach coordinator and volunteer.
