Colon surgery is also performed for non-cancerous conditions, such as benign polyps, strictures, Crohn's disease, and diverticulitis. Diverticulitis is quite common and is thought to be associated with the low fiber diets of the Western world. High pressure in the colon causes an out-pouching, or diverticula, to form. These diverticula can become infected causing pain in the left lower abdomen and fever. Most patients will respond to antibiotic treatment; however, a significant number of people will require surgery, either emergent or elective, to treat the diseased portion of the colon. This surgery can often be done laparoscopically, and your surgeon will advise you which surgery is best for you.
