Anterior Resection (AR) Surgery for Rectal Cancer at PI Health Cancer Hospital
Anterior Resection (AR) is a specialized surgical procedure aimed at treating cancer in the rectum or lower colon. At PI Health Cancer Hospital, our skilled colorectal surgeons utilize advanced techniques to perform AR surgeries, focusing on effectively removing cancer while preserving normal bowel function and minimizing the need for a permanent colostomy whenever possible.
What is Anterior Resection?
Anterior Resection (AR) is a surgical approach that involves removing a section of the rectum affected by cancer, along with nearby lymph nodes, and reconnecting the healthy parts of the bowel. This procedure is primarily used for rectal cancers found in the upper and middle sections of the rectum.
One of the key benefits of AR is that it helps preserve the anal sphincter muscles, enabling patients to have normal bowel movements without the necessity of a permanent stoma (colostomy).
When is Anterior Resection Recommended?
AR is typically recommended for:
- Early-stage rectal cancer (Stages I–III)
- Tumors situated in the upper or middle rectum
- Large benign polyps that can’t be removed through endoscopy
- Certain cases of diverticulitis or other rectal conditions
How is Anterior Resection Performed?
At PI Health Cancer Hospital, AR surgery can be conducted using:
- Open surgery
- Laparoscopic (minimally invasive) surgery
- Robotic-assisted surgery (for enhanced precision and quicker recovery)
Procedure Steps:
- General anesthesia is administered.
- The cancerous section of the rectum and nearby lymph nodes are excised.
- The remaining part of the colon is reconnected to the remaining rectum (this is known as a colorectal anastomosis).
- A temporary ileostomy may be created to safeguard the connection during the healing process (this is typically reversed after a few months).
Recovery After Anterior Resection
Hospital Stay:
Typically lasts between 4 to 7 days, depending on the surgical technique used and the patient’s overall health.
Postoperative Recovery:
Patients can gradually return to their normal diet.
Most people can expect to fully recover within 6 to 8 weeks.
Guidance is provided on managing bowel health and making necessary dietary changes.
Temporary Side Effects:
You might experience an increase in bowel movements.
There may be a sense of urgency to use the restroom.
Some patients may encounter “Low Anterior Resection Syndrome (LARS)
Risks and Complications
While anterior resection is generally safe, there are some potential risks to be aware of:
- Anastomotic leakage (a leak at the reconnection site of the bowel)
- Bowel dysfunction (like LARS)
- Infection or bleeding
- Rarely, urinary or sexual dysfunction
At PI Health Cancer Hospital, we take every precaution to minimize these risks, ensuring patients receive thorough care before and after surgery.
Life After Anterior Resection
Most patients find they can return to a normal, active lifestyle after AR surgery. While bowel habits may shift temporarily, they usually improve with time.
Support at PI Health includes:
- Stoma care (if a temporary ileostomy is performed)
- Dietary advice
- Pelvic floor therapy
- Psychological support if needed
