Summary

Ultrasound effectively diagnosed appendicitis in unclear cases and identified other pathologies. However, it did not alter management when clinical assessment was definitive for appendicitis.

Area of Science:

  • Medical Imaging
  • Diagnostic Ultrasound
  • Abdominal Surgery

Background:

  • Appendicitis diagnosis can be challenging, often requiring imaging to confirm.
  • Clinical evaluation alone may be insufficient in complex cases.

Purpose of the Study:

  • To evaluate the utility of ultrasound in diagnosing appendicitis.
  • To assess ultrasound's role in identifying alternative pathologies.
  • To determine if ultrasound influences management decisions.

Main Methods:

  • Clinical evaluation of 56 patients with suspected appendicitis.
  • Ultrasound examination to visualize the appendix and surrounding structures.
  • Analysis of ultrasound findings in relation to clinical presentation and management.

Main Results:

  • Ultrasound visualized the appendix in 18 patients and identified other pathologies in six.
  • Ultrasound was valuable in 25 patients with unclear clinical pictures, diagnosing appendicitis in 10.
  • Ultrasound aided diagnosis in three critically ill patients and identified six unsuspected conditions.
  • Management was unaffected when clinical diagnosis of appendicitis was clear.

Conclusions:

  • Ultrasound is a valuable tool for diagnosing appendicitis, especially in diagnostically ambiguous cases.
  • Ultrasound aids in identifying alternative pathologies, improving diagnostic accuracy.
  • Ultrasound does not change management when clinical signs strongly suggest or exclude appendicitis.
