Résumé
Colonic volvulus is a condition in which part of the colon twist around its axis. We reported here two different types of caecal volvulus, the first an 18 yrs old male who was diagnosed as recurrent appendicitis and at laparotomy had a caecal volvulus with a long mesentry. Laparotomy derotation and caecopexy was done. The second patient, a 32 years old female who was diagnosed with small bowel intestinal obstruction. At laparotomy, she had caecal volvulus due to arrested gut malrotation. She underwent right hemicolectomy. Both had uneventful recovery and were asymptomatic 3 years later. Colonic volvulus is a condition in which part of the colon twist around its axis, being enabled by a large, mobile segment of the colon with a small mesenteric fixation. Caecal volvulus is the second most common type of colonic volvulus after sigmoid volvulus[1], accounting for 10-40% of colonic volvulus. Patients with caecal volvulus may present with highly variable clinical presentations. Lack of familiarity of this condition is a factor contributing to diagnostic and treatment delays[2]. We report two cases one had a caecum with long mesentry and the other with situs inversus abdominis
