Significance of wall thickness in symptomatic gallbladder disease

One hundred cases of patients who underwent urgent cholecystectomy after presenting with symptoms of acute or subacute gallbladder disease were retrospectively reviewed. Sixty patients had pathologically proved acute cholecystitis, and 40 had chronic cholecystitis alone. One patient had an incidental gallbladder carcinoma, and four had global gangrene of the gallbladder. Focal ischemia, transmural hemorrhage, or focal necrosis (indicating more severe disease) was present in 19 patients. Fifty-four percent of patients had thin-walled gallbladders. Among patients with more severe acute disease, 56% had thin walls. Conversely, 24% of thin-walled gallbladders and 22% of thick-walled gallbladders had evidence of focal necrosis or gangrene. We conclude that gallbladder wall thickness, although demonstrable on preoperative ultrasound examination in all patients, does not correlate directly with severity of disease or pathologic findings.
