Summary

Ultrasound can detect acute gallbladder perforation by identifying specific signs like fluid collections and gallbladder wall changes. These findings aid in timely diagnosis and surgical intervention for patients with acute cholecystitis.

Area of Science:

  • Gastroenterology
  • Radiology
  • Surgical Pathology

Background:

  • Acute cholecystitis is a common surgical emergency.
  • Gallbladder perforation is a severe complication requiring prompt diagnosis.
  • Sonography is a primary imaging modality for acute cholecystitis.

Purpose of the Study:

  • To identify sonographic signs indicative of acute gallbladder perforation.
  • To differentiate between perforated and non-complicated acute cholecystitis using ultrasound.

Main Methods:

  • Retrospective analysis of patient files from two university hospitals (1978-1985).
  • Selection of patients with acute gallbladder perforation (n=9) and non-complicated acute cholecystitis (n=10) based on symptom duration and timing of sonography/operation.
  • Detailed analysis of sonographic findings in both groups.

Main Results:

  • Perforation group showed pericholecystic fluid, free peritoneal fluid, absent gallbladder wall echoes, echogenic areas with acoustic shadows, and inhomogeneous, echo-poor gallbladder walls.
  • Control group had distinct sonographic features not indicative of perforation.

Conclusions:

  • Specific sonographic findings are highly suggestive of acute gallbladder perforation.
  • Ultrasound is crucial for diagnosing gallbladder perforation in acute cholecystitis, guiding surgical decisions.
