Open/Laparoscopic Low Anterior Resections (LAR)

What are Open/Laparoscopic Low Anterior Resections?

A low anterior resection involves removing some or all of the sigmoid colon, which lies on the left side of your stomach and all, or nearly all of the rectum.

When are Open/Laparoscopic Low Anterior Resections done?

A LAR is commonly used to treat rectal cancer. Low anterior resections are most commonly used to treat stage 2 and 3 rectal tumours. Sometimes, they are used to treat stage 1 tumours. LAR can be used to treat upper, mid, and low rectal tumours. Dr Taylor will decide what type of procedure is best based on condition and unique factors.

What to expect from the procedure

You will have general anaesthesia before the surgery. LAR surgery can be done using different techniques. Dr Taylor will talk with you about which options are right for you. Depending on the type of surgery you have, he will make 1 or more incisions (surgical cuts) in your abdomen (belly).

The two main surgeries are open surgery and laparoscopic surgery.

During open surgery, one long incision is made on the abdomen. Next, the part of the rectum that contains the cancer or tumour will be removed through the incision.

During laparoscopic surgery, small incisions are made on your abdomen. Next, small surgical tools and a video camera will be put into the incisions to help guide Dr Taylor in removing the tumours.

Lastly, the incision will be sealed with sutures.
