These features may however be present with caecal pole tumour especially in the presence of tumour perforation or associated peritumoural inflammatory reaction. Caecal diverticulitis may actually be indistinguishable from carcinoma on the CT scan in about 10% of cases [15]. The early use of diagnostic laparoscopic in lower abdominal pain of indeterminate cause may be a useful tool in allowing accurate diagnosis and OSI-906 molecular weight planning the appropriate treatment. This is particularly important especially in young women with possible gynaecological pathology as the cause

of the pain. The surgical management of non-perforated caecal diverticulitis is highly controversial unlike that of the left sided diverticulitis [1–4, 6, 7]. Conservative management with

intravenous antibiotics and supportive care are the rule when a preoperative diagnosis of non-perforated caecal diverticulitis is made with confidence [3, 14, 15]. Conservative management can still be pursued even after an accurate diagnosis of uncomplicated caecal diverticulitis is made at diagnostic laparoscopy after an adequate washout. Complicated caecal diverticulitis with perforation can also be managed laparoscopically if the expertise is available [9, 16]. The variation in surgical resection ranges from an isolated diverticulectomy, ileocaecal resection or standard right hemicolectomy. Laparoscopic diverticulectomy has been described in the management of right-sided diverticulitis [16]. Fang et al [7] have recommended an aggressive Fludarabine manufacturer resection in a review of E7080 concentration 85 cases in an Asian population. Successful resolution of diverticulitis was achieved in less than 40% of their cases and this outcome informed their recommendation. Lane et al [6] in another series of 49 patients reported that 40% of their patients treated with diverticulectomy or antibiotics alone required subsequent hemicolectomy due to an on-going inflammatory process. Right hemicolectomy carries a higher morbidity and mortality but is generally recommended for an inflammatory mass where diverticulectomy is usually

impossible or when a carcinoma is suspected and an adequate lymphovascular clearance should be performed in such cases [5–7, 14, 15]. Our patient underwent a right hemicolectomy and standard lymphovascular clearance because of the findings of inflammatory mass in the presence of a normal appendix and a polypoid mass within the caecum. Conclusion Solitary caecal diverticulum is rare especially in the Caucasian populations. Therefore, a high index of suspicion is required in the diagnosis of caecal diverticulitis and should be considered as a possible differential diagnosis in patients presenting with acute right iliac fossa pain. Its diagnosis should particularly be suspected in patients with a longer history of pain with atypical presentations of acute appendicitis.
