**Core Concept**
Hirschsprung's disease is a congenital condition characterized by the absence of ganglion cells in the distal colon and rectum, leading to functional obstruction. The disease is typically diagnosed in infancy and requires surgical intervention to alleviate the obstruction and restore normal bowel function.

**Why the Correct Answer is Right**
The primary treatment for Hirschsprung's disease involves removing the affected segment of the colon and rectum, followed by a pull-through procedure to reestablish a normal anal sphincter mechanism. This approach aims to eliminate the obstructed segment and restore normal bowel function. The correct answer involves a procedure that is not part of this standard treatment approach.

**Why Each Wrong Option is Incorrect**
**Option A:** This procedure is actually a part of the treatment for Hirschsprung's disease, where the affected segment of the colon and rectum is removed and a pull-through procedure is performed to reestablish a normal anal sphincter mechanism.
**Option B:** This procedure is also a standard treatment for Hirschsprung's disease, involving the removal of the affected segment and reestablishment of a normal anal sphincter mechanism.
**Option C:** This option is incorrect because it is actually a part of the standard treatment for Hirschsprung's disease, involving the removal of the affected segment and reestablishment of a normal anal sphincter mechanism.

**Clinical Pearl / High-Yield Fact**
It's essential to note that the diagnosis of Hirschsprung's disease often involves a combination of clinical presentation, laboratory findings, and imaging studies. A key diagnostic clue is the presence of a transition zone between the affected and normal segments of the colon, which can be visualized on a barium enema study.

**Correct Answer: D.**
