Colonic diverticulum surgery is a minimally invasive procedure. Colonic diverticulum is very common and refers to the outward protrusion of the mucosal layer and mucosal muscle layer of the colon, which can form a pouch-like structure. If the patient does not have any clinical symptoms, no treatment is needed. If diverticulitis occurs and is recurrent and conservative treatment is ineffective, surgery may be an option. If it is complicated by perforation or bleeding, surgical treatment is also required, usually choosing a minimally invasive procedure called laparoscopic surgery. Before the surgery, relevant tests, such as routine blood work, coagulation, colonoscopy, electrocardiogram, etc., should be completed to evaluate the patient’s physical condition before deciding whether to proceed with the surgery. After the surgery, nutritional support therapy, anti-infection therapy, etc. should be provided to facilitate the patient’s recovery.
