Area of Science:

  • General Surgery
  • Diagnostic Accuracy
  • Appendicitis Management

Context:

  • Clinical examination is the primary method for diagnosing acute appendicitis.
  • Retrospective analysis of 327 emergency laparotomies.
  • Significant diagnostic challenges persist in acute appendicitis.

Purpose:

  • To evaluate the accuracy of pre-operative diagnosis in suspected acute appendicitis.
  • To determine the rate of unnecessary laparotomies.
  • To assess the impact of observation time on diagnostic accuracy and perforation rates.

Summary:

  • Surgeons' diagnostic accuracy was 69.4%, leading to a 28.4% overall unnecessary laparotomy rate.
  • In females aged 12-40, 45.6% of surgeries were not required.
  • Diagnostic accuracy decreased significantly with longer observation times (77.7% to 52.2%), while perforation rates increased (18.6% to 33.3%).
