It is essential to learn a little bit about the functioning of the digestive system to understand how the Lap LAR Ileostomy works. The food you eat passes through the oesophagus (food pipe) to the stomach, where the digestion process happens. The digested food then moves to the small intestine, where nutrients are absorbed. Everything that is left unabsorbed from here is waste which is sent to the large intestine or the colon. Your body reabsorbs some amount of water in the colon as the waste (stool) is sent to the rectum. The rectum holds the waste in the body for a while until it can be excreted through the anus.
What is Lap LAR?
The laparoscopic lower anterior resection is a surgery that is performed to treat cancers in the rectum. During the procedure, the part of the rectum which contains the cancer is removed, and the rest of the rectum is reconnected to the colon. The procedure can be performed using different techniques, and your medical caregiver will talk to you about your options. Depending on the decision, the surgeon will perform an open surgical procedure or a laparoscopic surgical procedure.
In an open surgical procedure during surgical gastro treatment in Sarjapur Road, one long incision is made in the abdomen to access the rectum. The part of the rectum with the cancer is removed through this incision.
In a minimally invasive surgery, a laparoscope is used to access the rectum through several small incisions in the abdomen. The procedure is performed, and the incision is closed.
Once the part of the rectum with the tumour is removed, it is reconnected to the colon with sutures (stitches) or metal staples. The joint where the two ends are reconnected is called anastomosis. The procedure takes about 4 hours, and you will be able to have normal bowel movements once you have recovered from the surgery. In many cases, an Ileostomy becomes necessary for a while after the LAR surgery.
What is an Ileostomy?
Until you recover from the LAR procedure, it is not possible to pass stool through the rectum and anus. Hence to stop the waste from entering the colon and rectum while the anastomosis is healing, an Ileostomy needs to be performed.
The ileum is the last and longest part of the small intestine, which connects to the colon (large intestine). An ileostomy is a procedure which stops the bowel movement from going to the colon to let the anastomosis heal.
During the procedure, the part of the small intestine is brought outside the body through an opening in the abdomen. This part of the ileum, which is now called a stoma, would look like a shiny pink protrusion. The bowel movement and gas can now leave the body through the stoma. Usually, a plastic pouch is wrapped around the stoma to collect the waste.
A wound, ostomy and continence (WOC) nurse will help you with care for the stoma and teach you how to look after it after the surgical procedure. The Ileostomy will typically be closed in a few months after the surgery. Consult with the doctors at Manipal Hospitals.
