Relationship between clinical and histopathological features of patients undergoing cholecystectomy

Cholelithiasis is most common disease of the gallbladder and cholecystectomy is the one of the most performed surgical procedure worldwide.

To assess the relationship between the demographic, biochemical, and histopathological variables of patients who underwent cholecystectomy.

Demographic, biochemical, and histopathological data of 5077 patients undergoing cholecystectomy were compared in terms of two different aspects: open cholecystectomy (OC group; n = 2090) versus laparoscopic cholecystectomy (LC group; n = 2987), and an elective group (n = 4814) versus an emergency group (n = 263).

A total of 5077 patients aged between 13 and 97 years were included in the study. Aspartate aminotransferase (AST) levels, alanine aminotransferase (ALT) levels, mean platelet volume, and prevalence of acute/chronic cholecystitis were significantly higher in the LC group than in the OC group. On the other hand, age, direct bilirubin level, thrombocyte count, and prevalence of gallbladder cancer/gangrenous cholecystitis were significantly higher in the OC group than in the LC group. Levels of AST, ALT, white blood cells, neutrophils, and some prevalence of acute/chronic active cholecystitis were higher in the emergency group than in the elective group. On the other hand, the lymphocyte count and prevalence of chronic cholecystitis/hyperplastic polyps were higher in the elective group than in the emergency group. Histopathological analysis identified 32 patients with malignant gallbladder cancer as follows: adenocarcinoma (n = 21), mucinous adenocarcinoma (n = 3), papillary adenocarcinoma (n = 3), adenosquamous carcinoma (n = 1), clear cell adenocarcinoma (n = 2), squamous carcinoma (n = 1), and hepatocellular carcinoma metastasis (n = 1).

Even when the appearance of gallbladder specimens is normal, histopathological assessment allows for early diagnosis of many unusual findings such as gallbladder cancer.
