Background:
The prevalence of cholelithiasis and gallbladder cancer may be different across ethnic groups.
Aim:
To study the prevalence of cholelithiasis and gallbladder cancer among Aymara individuals.
Material And Methods:
An abdominal ultrasound was carried out in a sample of 182 Aymara women aged 46 ± 16 years and 76 Aymara men aged 55 ± 16 years. In addition, the histopathological reports of both patients with a history of previous cholecystectomy and those operated after the study were reviewed.
Results:
Ultrasound was normal in 150 participants (58%), 76 had cholelithiasis (30%) and 32 (12%) had a history of cholecystectomy. Pathological reports of the excised gallbladder were available for 106 cases and showed a chronic cholecystitis in 98% of cases. Gallbladder cancer was not reported.
Conclusions:
There is a 42% prevalence of cholelithiasis and no gallbladder cancer in this sample of Aymara population.
