Laparoscopic 'sleeve' caecectomy for idiopathic solitary caecal ulcer mimicking appendicitis

Idiopathic ulcer of the caecum is a rare condition of unknown aetiology. Its clinical presentation may mimic various pathologies, including appendicitis, inflammatory bowel disease and caecal malignancy. A definitive diagnosis is rarely established preoperatively, and is usually only confirmed histologically following surgical resection. We report a case of a young patient with caecal ulceration presenting with symptoms and signs of appendicitis, in whom laparoscopic anterior 'sleeve' caecectomy was performed to excise an inflammatory-looking mass involving the caecum. Histological examination demonstrated a deep mucosal ulcer and subsequent colonoscopy did not reveal any further pathology.
