Diverticulitis is one common reason why patients may see a colorectal surgeon. In patients with diverticulitis, small pouches on the lower colon  become inflamed or infected. While conservative therapies like rest, dietary changes and antibiotics can be helpful for treating mild cases of diverticulitis, surgery may be necessary for more severe cases, which can cause pain, nausea, fever, constipation, and other symptoms. During surgery, Dr. Mithani resects the diseased segment(s) of the colon and reconnects the healthy segments. In many cases, this bowel resection surgery can be done using a minimally invasive technique.
