Lower anterior resection

Lower Anterior Resection (LAR) is a surgical procedure primarily used to treat rectal cancer. It involves the removal of a part of, or the entire, rectum (the lower part of the large intestine). This procedure is typically performed when the cancer is located in the upper part of the rectum.

Procedure

The procedure is performed under general anesthesia. The surgeon makes an incision in the lower part of the abdomen to access the rectum. The affected part of the rectum is then removed along with nearby lymph nodes to prevent the spread of cancer. The remaining part of the rectum is then reconnected to the colon (large intestine), allowing for normal bowel function post-surgery. In some cases, a temporary or permanent colostomy may be required.

Risks and Complications

Like any surgical procedure, Lower Anterior Resection carries certain risks and potential complications. These may include infection, bleeding, anastomotic leak (leakage of intestinal contents into the abdominal cavity), and changes in bowel function. Long-term complications may include sexual dysfunction and low anterior resection syndrome (LARS), a condition characterized by changes in bowel habits.

Recovery

Recovery from Lower Anterior Resection varies depending on the individual's overall health and the extent of the surgery. Hospital stay typically ranges from 5 to 10 days. Full recovery may take several weeks to months. During this period, patients may require a special diet and physical therapy to regain strength and bowel function.
