How many patients with surgically confirmed cecal volvulus have CT topogram findings?
How many patients with surgically confirmed cecal volvulus have CT topogram findings?
In this institutional review board–approved, HIPAA-compliant retrospective study, the CT and CT topogram findings in 11 patients (one man, 10 women; age range, 26–100 years) with surgically confirmed cecal volvulus and 12 control patients were reviewed.
What are the signs and symptoms of cecal volvulus?
Patients with cecal volvulus may present with colicky abdominal pain, nausea, vomiting, and obstipation ( 4 ), all of which are signs of small-bowel obstruction, a far more common entity.
How long does it take to recover from cecal volvulus surgery?
For the patients with cecal volvulus, the time between CT and surgery ranged between 3 hours and less than 24 hours (median, <24 hours). For the control patients, the time between CT and either intervention or the final clinical diagnosis ranged between 4 hours and 12 days (median, <24 hours)
What is abnormal peritoneal fixation and cecal volvulus?
Abnormal peritoneal fixation is a common anatomic variation that allows proximal colon mobility. Cecal volvulus may occur if there is an additional insult such as scarring, adhesions, or an abdominal mass that serves as a fulcrum for rotation.
What is cecal volvulus of the cecum?
Volvulus of the cecum is a torsion of the bowel around its own mesentery that often results in a closed-loop obstruction. Cecal volvulus can only occur in the small percentage (11-25%) of the population who have a developmental failure of peritoneal fixation, allowing the proximal colon to be free and mobile [ 1 ].
Is there a CT sign for volvulus?
A specific CT sign for volvulus is the “whirl” (Fig. 5A, 5B), which has been described in volvulus of the midgut, cecum, and sigmoid colon [ 2, 4 ]. The whirl is composed of spiraled loops of collapsed cecum and sigmoid colon. Low-attenuating fatty mesentery with enhancing engorged vessels radiate from the twisted bowel.
