Health-related quality of life in patients undergoing cholecystectomy

Abstract

This large-scale prospective cohort study of a Taiwan population applied generalized estimating equations to evaluate predictors of health-related quality of life (HRQOL) after open cholecystectomy (OC) and laparoscopic cholecystectomy (LC) procedures performed between February 2007 and November 2008. The Gastrointestinal Quality of Life Index and Short Form-36 were used in a preoperative assessment and in 3 rd month and 6 th month postoperative assessments of 38 OC and 259 LC patients. The HRQOL of the cholecystectomy patients were significantly improved at 3 months and 6 months postsurgery ( p < 0.05). At 3 months postsurgery, HRQOL improvement was significantly larger in LC patients than in OC patients. Patient characteristics, clinical characteristics, and health care quality were also significantly related to HRQOL improvement ( p < 0.05). Additionally, after controlling for related variables, preoperative health status was significantly and positively associated with each subscale of the Gastrointestinal Quality of Life Index and Short Form-36 throughout the 6 months ( p < 0.05). Patients should be advised that their postoperative HRQOL may depend not only on their postoperative health care but also on their preoperative functional status.
