**Core Concept**
Anastomosis of the small bowel involves the surgical connection of two segments of the small intestine, typically after resection due to a disease process such as Crohn's disease or a malignancy. This procedure is a critical aspect of gastrointestinal surgery.

**Why the Correct Answer is Right**
The most commonly used technique for small bowel anastomosis is the end-to-end anastomosis, also known as the end-to-end anastomosis using a single layer of sutures. This method involves aligning the two ends of the bowel and suturing them together using a continuous suture technique. The single layer of sutures provides adequate strength and prevents leakage, which is a major complication of bowel anastomosis. The use of a single layer of sutures also simplifies the procedure and reduces the risk of complications.

**Why Each Wrong Option is Incorrect**
**Option A:** Not applicable.
**Option B:** Not a standard technique for small bowel anastomosis.
**Option C:** Not a recognized method for small bowel anastomosis.

**Clinical Pearl / High-Yield Fact**
When performing small bowel anastomosis, it is essential to ensure that the bowel is not under tension, as this can lead to complications such as leakage or stricture formation. The use of a gentle, non-traumatic technique and the application of adequate sutures can help prevent these complications.

**Correct Answer: C. End-to-end anastomosis.**
