Department Of Surgical Gastroenterology And GI Oncology

The Department of Surgical Gastroenterology and GI Oncology is functioning from the year 1995. The 1st incumbent HOD was Dr.M.Subramanian. MS., M.Ch.

The department provides expert surgical services to the neighbouring districts of Dharmapuri, Osur, Krishnagiri, Kallakurichi, Namakkal, Erode & Tirupur in addition to the people of Salem. We deal with all gastroenterological disorders, in particular GI cancers. We do all sophisticated open surgical procedures of the GI tract from complex anal fistulas to complex liver, pancreas and esophageal surgeries. We provide bariatric surgical services as well. The department has performed and continues to do advanced laparoscopic procedures especially for GI cancers.

We have been on the mission of providing state of the art surgical care in the field of GI Surgery with a special focus on GI Oncology. We are continuously striving to make our department a centre for excellence in minimally invasive GI Surgery and GI Oncology. Our future goals are basic and clinical science research in GI Surgery, GI oncology and Robotic Surgery. Our efforts are underway for carrying out regular liver transplantation in our department. We are providing services that match international standards in GI Surgery.

We also impart scientific and surgical training to two MCh post graduates every year. The department encourages MS postgraduates to undertake dissertation topics related to Surgical Gastroenterology. We work in close liaison with the department of Medical Gastroenterology and are providing expert surgical help in the field of GI Surgery to other super-speciality and broad speciality departments. The Department has substantially shown good performance in every aspect performing major GI surgeries under the Chief Minister’s Comprehensive Health Insurance Scheme.
