This study on acute appendicitis found that routine investigations and peritoneal fluid cultures offered little benefit. Antibiotic treatment duration for simple appendicitis could be shortened, and ampicillin resistance is a concern.

Area of Science:

  • Surgery
  • Infectious Diseases
  • Clinical Diagnostics

Background:

  • Acute appendicitis is a frequent surgical emergency, particularly in developing urban areas.
  • Current diagnostic and treatment protocols for acute appendicitis involve clinical judgment, investigations, and antibiotic therapy.

Purpose of the Study:

  • To analyze current practices in diagnosing and managing acute appendicitis.
  • To identify areas for improvement in diagnostic accuracy and treatment efficacy.

Main Methods:

  • Retrospective review of 103 adult patients with histologically proven acute appendicitis at Aga Khan University Hospital.
  • Analysis of diagnostic investigations (leukocyte count, ultrasound) and treatment outcomes (antibiotic duration, culture studies).

Main Results:

  • Clinical diagnosis was sufficient; investigations like leukocyte count and ultrasound showed no clear diagnostic advantage.
  • Routine investigations (hemoglobin, electrolytes) provided no additional information.
  • Peritoneal fluid cultures had low yield (26%) and did not impact management of simple appendicitis.
  • High resistance (73%) to ampicillin was observed in bacterial peritonitis.
  • Antibiotic treatment duration for acute simple appendicitis could potentially be reduced to a single preoperative dose.

Conclusions:

  • Diagnostic investigations beyond clinical assessment may not significantly improve accuracy for acute appendicitis.
  • Current antibiotic regimens, including ampicillin use and treatment duration, require re-evaluation due to resistance and potential for shorter treatment courses.
  • Further studies are needed to define optimal antibiotic strategies for acute simple appendicitis.
