During the surgery, the part of the rectum where the tumor is located is removed without affecting the anus, and the colon is attached to the remaining part of the rectum so that after the surgery you will have normal bowel movements. The passage of stool this way is preserved.

Depending on your overall health, the usual hospital stay for a low anterior resection is four to seven days and recovery time can be up to six weeks long. However, despite undergoing complete surgical removal of the malignant tumor, some patients may experience recurrence of the cancer. If this is the case radiation therapy and chemotherapy will be used.

LAR patients can experience pain in their lower abdomen after surgery. Less common complications related to LAR include:

  • bleeding
  • infection
  • temporary difficulty with emptying the bladder
  • sexual dysfunction after surgery, in some men

For LAR you will be given general anesthesia.

A LAR surgery is performed following these steps:

  • the surgeon makes an incision in the abdomen
  • the cancer and margins of normal tissue on each side of the tumor are removed, along with nearby lymph nodes, and fatty and fibrous tissue around the rectum
  • the colon is reattached to the rectum that is remaining, this way a permanent colostomy will not be necessary

It is common for a temporary ileostomy to be made if radiation and chemotherapy have been given before surgery. During the procedure, the last part of the small intestine called the ileum is brought out through a hole in the abdominal wall. Usually this can be reversed and the surgeon reconnects the intestines about 8 weeks later.

If the cancer is lower in the rectum:

  • the cut end of the large bowel can be attached directly to the anus
  • a temporary colostomy might be performed
  • after the patient has recovered from the surgery, the temporary colostomy is removed and stool is again passed normally through the large intestine
  • the colon is resewn to the anus

If you have been diagnosed with rectal cancer, your doctor may recommend a low anterior resection surgery. Ask your doctor about the minimally invasive da Vinci surgery to learn more about its advantages! 

da Vinci surgery requires just a few small incisions. The system features a magnified 3D high-definition vision system and special instruments that bend and rotate better than a human wrist. da Vinci LAR surgery offers the following potential benefits compared to traditional laparoscopy:

  • faster recovery
  • fewer major complications
  • less blood loss and pain
  • lower conversion rate to open surgery
  • shorter hospital stay
  • small incision for minimal scarring
  • quicker return of bowel function, sexual function, urinary function and to a normal diet

The da Vinci System translates the surgeon’s hand movements into smaller, more precise movements of tiny instruments inside your body.
