What condition is characterized by the twisting of the cecum causing obstruction?

Cecal volvulus refers to the condition in which the cecum, a pouch connected to the large intestine, twists around itself. This twisting, or volvulus, leads to an obstruction in the bowel, which can result in severe abdominal pain, vomiting, and potentially compromised blood flow to the affected area. When the cecum twists, it can obstruct the intestinal lumen, preventing the passage of contents through the bowel, which may necessitate surgical intervention to correct the twist and restore normal bowel function.

In contrast, other conditions listed do not specifically involve the cecum or twisting leading to obstruction. Intussusception involves a part of the intestine telescoping into an adjacent segment, which is a different mechanism of obstruction. A pilonidal cyst is a sac-like structure that forms in the skin, often at the tailbone, and does not involve the intestinal tract. Dehiscence refers to a surgical wound that has separated, rather than an issue originating from the gastrointestinal tract. Therefore, the defining characteristic of cecal volvulus aligns directly with the question about twisting of the cecum causing obstruction.
