Prospective observational study on cholelithiasis in patients with carcinoma gall bladder in a tertiary referral hospital of Eastern India

摘要

Context: Gallbladder carcinoma (GBCA) is the fifth most common types of gastrointestinal malignancy and is the most common malignancy of the biliary tract. Cholelithiasis, gallbladder polyps, porcelain gall, and choledochal cysts are common known associations with GBCA. Because of the better understanding of the etiopathogenesis, the traditional nihilistic attitude toward the prognosis has, over the years, given way to greater interest and hope for treating the disease. Long-term survival has been reported in patients with resectable lesions in the hands of expert hepatobiliary surgeons. Objective: This prospective observational study was conducted at a tertiary referral hospital of Eastern India on patients with the diagnosis of GBCA. The main objective was to assess the incidence of gallstones in patients with GBCA, and the relationship, if any, between the size and number of stones and GBCA in our patient cohort. Materials and Methods: This prospective observational study was conducted, over a period of 2 years, at a tertiary referral hospital of Eastern India which caters to patients from all the neighboring districts. A total of 54 patients with the diagnosis of GBCA were included in the study. Data on their demographic and clinical profile, the incidence of associated gallstones, their size (3 or ≥3cm), and number (solitary or multiple) were collected. Known predisposing factors of GBCA, if any, in those presenting without stones were noted. Results: GBCA was found to afflict females 2.4 times as frequently as males. Patients, irrespective of their sex, were mostly in their sixth decade. Approximately three-fourth of the cases had associated cholelithiasis. The number of stones had no correlation with the disease. However, contrary to available published data, stones 3 cm were significantly more common in our study cohort. Conclusion: The results of this study reaffirm that cholelithiasis is a strong predisposing factor for GBCA and females with gallstones in their sixth decade, are more at risk. Although number of stones was not found to be an independent risk factor, patients with stones 3 cm (mostly multiple) were found to be more at risk in our study.
