Mobile caecum is an anatomical variant and is often defined as a failure of the caecum, terminal ileum, and right colon, along with the mesentery, to fuse to the posterior parietal peritoneal wall. This results in increased mobility of the caecum.
It has been estimated to occur in 10-20 % of the population 4.
It is asymptomatic in many cases, but if symptomatic, may result in mobile caecum syndrome.
- caecal volvulus: rare, but may also carry a higher complication rate in the event that it occurs
- mechanical bowel obstruction: rare
Treatment and prognosis
Caecopexy (i.e. surgical fixation of the caecum) is sometimes performed in selected symptomatic cases.
