A colectomy procedure to remove the left side of the colon is called Left Hemi-Colectomy. The surgeon removes the damaged part of the colon and reattaches the healthy parts. This surgery is performed for treating colonic cancer or bowel diseases like Crohn’s disease or diverticulitis. In Laparoscopic Left Hemi-Colectomy, small incisions are made in the abdominal wall and a thin scope with lens and light is inserted, along with other surgical instruments through the small incisions. In the open approach, longer cuts are made to access the colon. Due to larger cuts, recovery may take longer.
