Background: Since solitary caecal diverticulum is a rare condition, it is challenging to detect outside of preoperatively. A rare cause of acute abdomen, caecal diverticulitis typically manifests similarly to acute appendicitis. Treatment for this clinical condition is still debatable. Methods: In this observational study we report three cases of caecal diverticulitis. Three middle aged (27-67yrs)malepresented with right sided lower abdomen pain mimicking appendicitis. Results: One of them diagnosed preoperatively and other two patients were diagnosed in operation room (OR). Initial medical treatment failed in first case and subsequently was managed via Laparoscopic Right Hemicolectomy and Ileo- Ascending anastomosis done. The second patient was detected during laparoscopic appendicectomy, where appendectomy and diverticulectomy with primary repair was done. Thirdcase was detectedwhile exploring the abdomen for suspected appendicitis. The patient had undergone refashioning of margin and primary repair of caecum. Conclusion : Caecal diverticulitis is a rare clinical entity often encountered during operative intervention for acute appendicitis. High index of suspicion and modern imaging may diagnose it preoperatively. Management is diverse and includes both medical and surgical therapy.
