The bowel is a tube of intestine which runs from the stomach to the back passage. The lower half of the bowel is called the colon. The colon runs from the right side of the waist line, up to the right ribs, round across the upper part of the belly and passes down the left side. There it runs backwards into the pelvis as the back passage, where it is called the rectum.
Anterior resection of the rectum surgery (also known as low anterior resection surgery or LAR) is a medical process used to treat the rectum, naturally after the patient has suffered from rectal cancer. LAR is especially preferred when cancer has affected the upper two-thirds of the rectum. Some stage I and most stage II or II rectal cancers occur close to where the rectum joins with the colon in the upper two thirds of the rectum. During low anterior resection surgery, surgeons attempt to remove the cancerous tumor without affecting the anus. The colon is connected to the anus letting waste to leave the body in the normal manner.
Laxatives and enemas are performed before a low anterior resection surgery to make your bowel clean. The procedure is performed under general anesthesia, and the surgeon makes an incision in the abdomen to remove the cancerous tissue and fatty deposits. The colon is then rejoined to the rectum. After a low anterior resection surgery you can avoid a colostomy.
The patient will have a fine plastic tube, to drain the stomach. Swallowing may be a little uncomfortable. The wound will have a dressing and a drainage tube. The medical staff will prescribe pain medication. The day after surgery the patient should be able to get out of bed and start moving around.
For a few days the candidate will have a fine drainage tube in the penis or front passage to drain the urine from the bladder until they are able to get out of bed easily.
After a few days you will be coming to your normal activities. You will be allowed to stay in the family accommodation where you will be able to rest in comfort with your companion. The patient will be able to return home after 10 – 14 days.
Post-operative care procedure has thoroughly been envisaged and framed out by Dr.K.N.Srikanth MS, FRCS, which includes rest and routine follow-up physical examinations, blood tests, and imaging studies. Regular colorectal screening is recommended for high-risk patients. In this way, doctors can detect cancer much earlier, thus, negating the need for anterior resection of rectum surgery.
