A General Surgeon is a medical doctor who specializes in the diagnosis and operative and peri-operative care of patients suffering from a multitude of surgical conditions affecting virtually any area of the body but primarily focused on the abdomen. Additionally, the surgeon is usually responsible for the comprehensive management of the trauma victim and the critically ill surgical patient. General Surgeons are skilled in the use of minimally invasive techniques such as laparoscopy and endoscopies, and more and more are becoming proficient at robotic surgery techniques. Common surgical conditions include inguinal, hiatal, and other hernias, gallstones, appendicitis, breast lumps and tumors, thyroid nodules, pancreatitis, bowel obstructions, and colon cancer. Some General Surgeons pursue further specialization in the fields of Pediatrics (Pediatric General Surgeon), Oncology, Vascular, Trauma, Hospice and Palliative Medicine, and Transplant Surgery.
