Low Anterior Resection (LAR)
Low Anterior Resection (LAR) is a surgical procedure used to remove diseased or cancerous portions of the rectum while preserving the anal sphincter whenever medically appropriate. It is commonly performed as part of rectal cancer treatment and may also be considered for certain other rectal conditions. The goal is to remove the affected tissue while maintaining bowel continuity and supporting normal bowel function.
When Is Low Anterior Resection Recommended?
A Low Anterior Resection may be recommended for selected patients with rectal cancer, particularly when the tumor can be safely removed without requiring permanent removal of the anus. Your colorectal or gastrointestinal surgeon will assess the tumor location, size, stage, overall health, and other clinical factors before recommending surgery.
How Is LAR Performed?
During the procedure, the surgeon removes the affected section of the rectum along with surrounding tissues and nearby lymph nodes when required. The remaining colon is then connected to the remaining rectum or anus to restore bowel continuity. Depending on the individual case, a temporary ileostomy may be created to protect the surgical connection while it heals.
Recovery After LAR
Recovery varies depending on the surgical approach, overall health, and whether additional treatments such as chemotherapy or radiation therapy are required. Patients may initially experience changes in bowel frequency, urgency, or stool consistency. Follow-up care, dietary guidance, medications, and regular monitoring can help manage these changes during recovery.
