Acute appendicitis is the most common acute surgical condition of the abdomen. Diagnosis is made based on full clinical history and examination as well as supported by a routine blood investigation and urine test. Prompt diagnosis and surgical referral may reduce the risk of perforation and prevent complications. The mortality rate of non-perforated appendicitis is less than 1 percent. Perforated appendicitis is associated with a higher mortality rate - as high as five percent and may be particularly more in extreme of age group attributed to delay in clinical presentation or diagnosis in the younger group and multiple co-morbidities in the elderly group. The aetiology is unknown. It may be linked with lack of fibre, familial tendency, or viral infection. It may be precipitated by faecaliths. The commonest site of the appendix is retrocaecal.
We report a case of a 46 year old male who was admitted under the surgical service in Mid-Western Regional Hospital, Limerick with suspected appendicitis which turned out to be a perforated caecum, a rare complication of an acute appendicitis. We performed a literature review comparing two main approaches - right hemicolectomy and primary closure with omental patch - discuss and highlight their differences as well as a guide to its management.
There are limited studies to compare these two surgical options in the literature. A larger prospective study is needed to compare both approaches and long term outcome.
