**Core Concept**
Abdominal rectopexy is a surgical procedure used to treat complete rectal prolapse, characterized by the rectum protruding through the anus. This condition occurs due to weakened pelvic floor muscles and connective tissue. Abdominal rectopexy involves securing the rectum to the sacrum using mesh or sutures to restore its normal anatomical position.

**Why the Correct Answer is Right**
The correct answer is abdominal rectopexy because it is the most effective surgical approach for treating complete rectal prolapse. This procedure addresses the underlying anatomical issue by repositioning the rectum and strengthening the pelvic floor muscles. The rectum is fixed to the sacrum using a mesh or sutures, which helps to prevent further prolapse. This approach is preferred over other options because it provides long-term relief from symptoms and reduces the risk of recurrence.

**Why Each Wrong Option is Incorrect**
**Option B:** Delorme's procedure is a less invasive surgical approach that involves partial rectopexy and is typically used for incomplete rectal prolapse. It is not the preferred treatment for complete rectal prolapse.
**Option C:** Anterior resection is a surgical procedure used to treat rectal cancer or other rectal conditions, not complete rectal prolapse. It involves removing the affected portion of the rectum and reattaching the remaining rectum to the colon.
**Option D:** Goodall's procedure is not a recognized surgical approach for treating rectal prolapse. Goodall's rule is a clinical guideline used to determine the location of anal fistulas, not a treatment for rectal prolapse.

**Clinical Pearl / High-Yield Fact**
A key consideration in choosing the appropriate surgical approach for rectal prolapse is the patient's overall health and the severity of the condition. Abdominal rectopexy is generally recommended for patients with complete rectal prolapse and weakened pelvic floor muscles.
