How Do Quality-of-Life and Gastrointestinal Symptoms Differ Between Post-cholecystectomy Patients and the Background Population?

Abstract

Previous studies have indicated a correlation between indication for cholecystectomy and long-term gastrointestinal quality-of-life (QoL). The aim of the present study was to compare QoL in a post-cholecystectomy cohort with the background population and with historical controls. A post-cholecystectomy study group (on average 4 years after cholecystectomy) was compared with a control group from the background population using the Gastrointestinal Quality-of-Life Index (GIQLI). EQ-5D scores were compared with expected scores derived from recent historical data. The post-cholecystectomy study group (N=451) had better QoL measured by the EQ-5D compared with historical controls (p<0.001), similar total GIQLI scores as the control group (N=390), but scored worse on the GIQLI gastrointestinal symptoms subscale score (p<0.001). The results include an item-by-item breakdown of the GIQLI questionnaire where the scores for diarrhea, bowel urgency, bloating, regurgitation, abdominal pain, flatus, fullness, nausea, uncontrolled stools, belching, heartburn, restricted eating, and bowel frequency were found to be significantly lower (i.e. worse) in the post-cholecystectomy cohort than in the control group. The opposite was true for relationships, endurance, sexual life, physical strength, feeling fit, not being frustrated by illness, and being able to carry out leisure activities, i.e. items related to general performance and well-being. In this study, QoL after cholecystectomy was good, but there was an increased prevalence of gastrointestinal symptoms compared to the background population.
