Study of associationship between gall stone composition and bacteriological spectrum in chronic calculous cholecystitis

Background Chronic calculous cholecystitis is the benign disease affecting the gallbladder, frequently female population of middle age. This study was done with the objective of study the composition of gall stones, microbiological spectrum and their association in chronic calculous cholecystitis patients.

Methods This is a prospective study done on 131 cases of chronic calculous cholecystitis admitted in the department of General Surgery (DNB), K.K. Hospital, Lucknow for cholecystectomy during January 2018 to January 2019. 31 patients were excluded from the study based on exclusion criteria. USG of abdomen was done in all 100 cases. All patients underwent either open cholecystectomy (OC) or laparoscopic cholecystectomy (LC).During cholecystectomy bile was aspirated and was sent to laboratory for culture. Gallstone retrieved from the specimen and was classified based on morphology.

Results Out of 100 cases, 76 cases underwent LC and 24 cases were done with OC. Female dominance was seen in the study (69%). The predominant type of gall stone in present study was cholesterol (68%). The bile culture test was positive in 20% of cases. The most common isolated microorganism was E. coli (50%). No significant association was observed between composition/type of gall stone and isolated microorganisms in bile (p=0.126).

Conclusions The result concluded that chronic calculous cholecystitis was more common in females of middle age group. Bile culture was positive in 20% cases and E. coli was the common organism isolated. Identification of the type of organism is crucial for early management of the disease condition.
