General surgery is a surgical area of expertise that greatly focuses on different abdominal contents like the appendix, the gallbladder, the bile ducts, the pancreas, colon, small bowel, liver, stomach, and esophagus. Sometimes, it comprises the thyroid gland, but this largely depends on the referral patterns. General surgery also successfully deals with diverse diseases that affect peripheral vascular surgery, hernias, breast, trauma, soft tissue, as well as skin.
