General surgery, despite its name, is a surgical specialty that focuses on surgical treatment of abdominal organs, e.g. intestines including esophagus, stomach, colon, liver, gallbladder and bile ducts, and often the thyroid gland, hernias and breasts.

In the last few years minimally invasive surgery has become more prevalent. Minimally invasive surgery (sometimes called laparoscopic surgery) is done through small incisions. Using specialized techniques, miniature cameras with microscopes, tiny fiber-optic flashlights and high definition monitors. Dr. Denes performs most of his surgeries through an incision that requires only a stitch or two to close.

For patients, minimally invasive surgery means less trauma to the body, less blood loss, smaller surgical scars and less need for pain medication. Patients leave the hospital sooner after minimally invasive surgery and return to normal activities sooner than with conventional open surgery.
