Relevant statistical tests were applied, using SPSS version 13.0. From the studied patients 62 females, 38 males with a mean +/- SD of 60.8 +/- 15.9 years, 66 were underweight, 23 were overweight, and only 11 patients had normal weight. Most of the patients 76 had calculous cholecystitis, of which 50 65.8% were female, and 26 34.2%, were male. Seven females 11%, and 14 males 37% revealed jaundice p<0.002. Most 72% had a history of narcotics abuse, of which 69 95.8% abused opiates constantly, and 3 4.2% abused recreationally. A significant p<0.01 relationship was found between acute cholecystitis and opiate addiction. Opiate addiction was more common in patients from rural areas than urban p<0.03. Seventeen female patients 27.4% had a history of taking oral contraceptives. The patients were mostly from low socio-economic populations, and rural areas.
