Purpose: The objective of this study was to investigate the association of quality-of-life status with baseline laboratory findings among Taiwanese adults having symptomatic gallstone disease., Methods: A prospective quality-of-life survey was administered at a tertiary referral medical center among 102 consecutive adults with symptomatic gallstone disease. Patients underwent regular laboratory testing at admission and were evaluated using the 36-Item Short-Form Health Survey (SF-36) and the Gastrointestinal Quality of Life Index (GIQLI). Correlation and regression models were used to investigate quality-of-life predictors., Results: Compared with the general Taiwanese adult population, patients having symptomatic gallstone disease had significantly poorer performance on all eight SF-36 subscales (P < 0.001). Total GIQLI showed moderate to strong correlation with all eight SF-36 subscale scores (gamma = 0.29 ~ 0.62, P < 0.05). In multivariate analysis, serum levels of direct bilirubin (beta = -32.6, P = 0.001) and alkaline phosphatase (beta = -13.6, P = 0.032) were predictive of worse total GIQLI (adjusted R (2) = 0.183)., Conclusions: Symptomatic gallstone disease may considerably affect patient quality of life in terms of general health status and gastrointestinal-specific measures. Before gallstone surgery, serum levels of direct bilirubin and alkaline phosphatase significantly correlated with quality-of-life measures and can be used to evaluate patient well-being at admission.

Background and Aim: To examine associations between lifestyle risk factors and intrahepatic stone (IHS), we conducted a case-control study in Taiwan, which has the highest incidence of IHS in the world., Methods: Study subjects were 151 patients newly diagnosed with IHS at Chang Gung Memorial Hospital between January 1999 and December 2001. Two control subjects per case were selected randomly from patients who underwent minor surgery at the same hospital and from family members or neighbors of the hospital staff. Controls were matched to each case by age and gender. Information on lifestyle factors was collected using a self-administered questionnaire. Strength of associations was assessed using odds ratios derived from conditional logistic models., Results: Female patients were significantly shorter than female controls. Compared to subjects with two or fewer children, odds ratios for those with six or more children were 20.4 in men (95% confidence interval, 1.89-221) and 2.82 (0.97-8.22) in women. Increasing level of education lowered the risk of intrahepatic stone (trend P = 0.004 for men and < 0.0001 for women). Women who had consumed ground-surface water for a long period had a somewhat increased risk (trend P = 0.05)., Conclusion: Lower socioeconomic status and poor hygiene may be involved in the development of intrahepatic stones.
