Cholecystectomy or Cholelithiasis – a Missed Marker for Hyperlipidaemia? A Combined Retrospective and Prospective Study

Sivakumaran Sabanathan, Soonita Oomeer, Lloyd R Jenkinson

Abstract


Background: Multiple studies have shown an association between gallstones and abnormal lipids and the latter increases the risk of coronary artery disease and stroke. Our study investigates the current incidence of lipid abnormalities in patients who have undergone cholecystectomy (retrospective study) and who have gallstones (prospective study).
Methods: We conducted a retrospective analysis of the lipid profiles of 715 patients who underwent cholecystectomy in a rural district general hospital from 2003 to 2006. Details of the cholecystectomy patients were obtained from Patient Information and Management System (PIMS) and cross-referenced with biochemical and histological databases. Following this a prospective study was undertaken of 129 patients presenting with gallstones.
Results: Of the 715 patients, three quarters were women. Only 36.2% of women and 36.9% of men who had a cholecystectomy had a full lipid profile including high density lipoproteins (HDL) and low density lipoproteins (LDL). Of these, 76.4% of women and 70.7% of men had an abnormal lipid profile. In the prospective group, 91.1 % of women and 96.3 % of men had a full lipid profile. These were abnormal in 81.4% of women and 70.4 % of men. Hypercholesterolemia and raised LDL were the most common abnormalities in both sexes. Hypertriglyceridaemia was common in both sexes in both the groups.
Conclusions: Patients who have had a cholecystectomy or gallstones should have a full fasting lipid profile, including HDL and LDL, as a large proportion will be abnormal. Current guidelines suggest they are at an increased risk of cardiovascular disease and should be treated.
