Caecal Diverticulitis with Perforation is a condition characterized by the inflammation and potential rupture of diverticula, which are small pouches that form in the wall of the caecum, the initial section of the large intestine. This rupture can lead to serious complications such as infection and peritonitis, necessitating prompt medical attention and often surgical intervention. Treatment typically involves segmental resection of the affected colon and diversion with a proximal end colostomy or a Hartmann's procedure (HP). The incidence of this condition ranges from 0.04% to 2.1%. A 45-year-old male was admitted with complaints of abdominal pain, vomiting, and fever persisting for three days. His medical history includes Type II Diabetes Mellitus (T2DM), Systemic Hypertension (HTN), and Dyslipidemia (DLP), all of which are currently being treated.
