Which statement describes the LAR procedure?

• A. Low anterior resection; resection of low rectal tumors through an anterior abdominal incision
• B. Abdominal perineal resection with permanent end colostomy
• C. Ureterostomy
• D. Ileal conduit creation for urinary diversion

Answer: (A)

Low anterior resection is a bowel-sparing operation for cancers in the lower rectum. It is performed through an abdominal approach with the goal of removing the diseased portion while preserving the anal sphincter and restoring bowel continuity, often with a colorectal or coloanal connection. The described statement—resection of low rectal tumors through an anterior abdominal incision—fits this procedure because it emphasizes the abdominal approach and preservation of continence. In contrast, removing the rectum and anal canal with a perineal component (abdominoperineal resection) leads to a permanent end colostomy, and the other options refer to urinary diversions rather than colorectal surgery.
