Gallstone disease prevalence in Mexico mirrors Western countries. Chemical analysis of Mexican gallstones reveals a similar mixed composition to those found in Western populations, indicating comparable physiochemical characteristics.

Area of Science:

  • Gastroenterology
  • Biochemistry
  • Public Health

Background:

  • Gallstone disease is prevalent in Mexico, with rates comparable to industrialized Western nations.
  • Western populations predominantly develop cholesterol gallstones.
  • Data on the chemical composition of gallstones in Mexico is lacking.

Purpose of the Study:

  • To determine the physiochemical characteristics of gallstones in the Mexican population.
  • To compare the chemical composition of Mexican gallstones with those from Western countries.

Main Methods:

  • Analysis of gallstone specimens from 59 patients undergoing surgery for symptomatic cholelithiasis.
  • X-ray diffraction was used for chemical analysis of gallstones.
  • Patients were recruited from five Mexican states and Mexico City.

Main Results:

  • 71.2% of analyzed gallstones were of mixed chemical composition.
  • The findings indicate a similarity in gallstone composition between Mexican and Western patients.

Conclusions:

  • The chemical composition of gallstones in Mexican patients is comparable to that observed in Western countries.
  • This study provides crucial data on the physiochemical properties of gallstones in a previously understudied population.
