Subtotal Colectomy involves the removal of a portion of the colon, often used to treat conditions like colorectal cancer, ulcerative colitis, or other colon diseases. The procedure typically removes a large part of the colon, leaving the remaining part to function normally.

The surgery can be performed either through open surgery or laparoscopically, depending on the patient's condition and the extent of disease. In cases where cancer is present, additional treatments like chemotherapy or radiation may be required.

Postoperative care includes monitoring for complications such as bleeding, infection, or bowel obstruction. Patients may need to adopt a special diet and avoid heavy physical activity while recovering.

Subtotal colectomy provides significant relief for patients with severe colon diseases, offering the best chance for survival and symptom relief, especially when performed early.
