**Core Concept**
A Richter hernia refers to a type of hernia where only a portion of the intestinal wall, usually involving a portion of the circumference of the intestine, protrudes through a defect in the fascia, whereas the rest of the intestinal wall remains in place. This occurs due to the herniation of a loop of intestine through a fascial defect, often resulting in partial bowel obstruction and potential complications.

**Why the Correct Answer is Right**
In a Richter hernia, the herniated portion of the intestine may not exhibit the typical signs of bowel obstruction, such as severe abdominal pain, vomiting, and constipation, due to the compensatory function of the remaining intact intestinal wall. However, complications such as ischemia, necrosis, and perforation can still occur if not promptly treated. The herniated portion of the intestine may undergo ischemia due to impaired blood supply, leading to potential gangrene and perforation.

**Why Each Wrong Option is Incorrect**
**Option A:** This option may be incorrect as it does not accurately describe the characteristic features of a Richter hernia.

**Option B:** This option may be incorrect as it does not provide sufficient information about the pathophysiology and complications associated with Richter hernia.

**Option C:** This option may be incorrect as it does not accurately describe the clinical presentation and complications of a Richter hernia.

**Clinical Pearl / High-Yield Fact**
Richter hernia is a type of hernia that requires prompt surgical intervention to prevent potential complications, including ischemia, necrosis, and perforation of the herniated intestinal segment.

**Correct Answer: C.**
