This paper will discuss adult patients to include patients aged 12 years and older diagnosed with acute appendicitis. Data collected included demographic data, clinical presentation, duration of symptoms and reasons for presentation delay, diagnostic investigations, operative and histology findings, length of hospital stay, and mortality so we can gain a better understanding of an ailment which has caused many emergency and operating room visits.
Predominant presenting symptoms for one study of a patient with appendicitis were right iliac fossa pain (95%), nausea (80%), and vomiting (73%), with 63% of patients presenting 2 days after onset of symptoms. Fever was present in 15% and only 31% of patients gave a typical history of acute appendicitis of vague peri-umbilical pain. The negative predictive values of white cell count and C-reactive protein for acute appendicitis were 28% and 50%, respectively. Sensitivity of the ultrasound to detect acute appendicitis was 60% with a negative predictive value of 31%; 30% of patients had complicated appendicitis. Histology results showed a normal appendix in 11% of patients. The 30-day mortality rate was 1.4%.
Though we are told in many books of the infamous belly pain, patients with acute appendicitis rarely present with a typical history of vague peri-umbilical pain. The negative predictive values of both white cell count and ultrasound proved that neither of these measurements was accurate in the diagnosis of acute appendicitis. Most of
