**Core Concept:** Volvulus is a surgical emergency characterized by the rotation of the large bowel on its vascular pedicle, leading to reduced blood supply and potential gangrene. It can affect any part of the gastrointestinal tract (e.g., small bowel, colon), but the most common is sigmoid volvulus.

**Why the Correct Answer is Right:** Statement C is false because in the case of sigmoid volvulus, the sigmoid colon twists around the mesenteric axis, causing impaired blood supply and potential intestinal necrosis.

**Why Each Wrong Option is Incorrect:**

A. This is true, as volvulus occurs due to the rotation of the affected bowel part on its vascular pedicle, leading to reduced blood supply and gangrene.
B. This is also true, as the lack of early diagnosis and treatment can result in serious complications and even death.
D. This is false, as volvulus typically involves the large bowel, not the small bowel.

**Clinical Pearl:** Early diagnosis and prompt surgical intervention are crucial in managing volvulus to prevent complications and mortality. The classic presentation includes intermittent abdominal pain, vomiting, and a palpable mass.

**Correct Answer:** C (False) - Volvulus typically involves the large bowel, not the small bowel.
