Which of the following is NOT true about ligament of Treitz?
**Core Concept**
The ligament of Treitz, also known as the suspensory muscle of the duodenum, is a crucial anatomical structure that separates the duodenojejunal junction from the rest of the duodenum. It plays a vital role in maintaining the integrity of the gastrointestinal tract and preventing reflux of intestinal contents into the stomach.
**Why the Correct Answer is Right**
The ligament of Treitz is a fibromuscular structure that consists of a thickened fold of the duodenojejunal junction. It is characterized by the presence of a smooth muscle layer, which allows for its contraction and relaxation. This mechanism helps to maintain the integrity of the gastrointestinal tract and prevents the reflux of intestinal contents into the stomach. The ligament of Treitz also serves as an attachment point for the superior mesenteric vessels and the pancreatic head.
**Why Each Wrong Option is Incorrect**
**Option A:** The ligament of Treitz is not a true ligament, but rather a fibromuscular structure. This statement is incorrect, as the ligament of Treitz is indeed a fibromuscular structure, but it is not a true ligament.
**Option B:** The ligament of Treitz does not contribute to the formation of the duodenal loop. This statement is incorrect, as the ligament of Treitz does contribute to the formation of the duodenal loop, which is a normal anatomical variation.
**Option C:** The ligament of Treitz is not related to the celiac trunk. This statement is incorrect, as the ligament of Treitz is indeed related to the celiac trunk, as it serves as an attachment point for the superior mesenteric vessels.
**Clinical Pearl / High-Yield Fact**
The ligament of Treitz is a critical anatomical landmark that should be remembered by surgeons, radiologists, and gastroenterologists. It is a common site for intestinal obstruction and should be carefully evaluated during diagnostic imaging and surgical procedures.
**Correct Answer:**
Ligament of Treitz is not a true ligament.
