Laparoscopic Cholecystectomy for Gallbladder Polyps: Is It Overtreatment?

Abstract

The gallbladder polyp (GP) is an accepted risk factor of gallbladder cancer and an indication for laparoscopic cholecystectomy (LC). Generally, the pathologic result of GPs is benign, but it is difficult to distinguish a potential malignancy or a stone without pathological evaluation. This study compared the indication and pathologic result of cholecystectomy performed due to GP in our clinic. This study employed retrospective data analysis. Patients who underwent LC from August 2021 through August 2024 were included in the study. Demographic features, operation status, indications for surgery, hospital stay, concomitant surgery, pathologic outcomes, and complications were recorded from patients' data. Polyp sizes and number of polyps were taken from ultrasonography (USG) data. A total of 533 patients were included in the study. The mean age was 44.31 ± 12.14, and 64.35% (n = 343) were of female gender. Twenty patients (3.75%) underwent surgery for GP. The mean polyp size was 7.47 mm (2-15); 65% of the patients (n = 13) had multiple polyps, and 35% (n = 7) had a single polyp. The mean hospital stay was 1.59 ± 0.88 days. The pathologic result of GP was pseudopolyp in 55% (n = 11) of cases and non-polyp in 45% (n = 9). One patient (0.18%) who underwent an operation for gallstone had a malignancy. The sensitivity of USG in detecting polyps was found to be 64.7%. The complication rate was 1.5% (n = 8). The pathological result of many patients who undergo cholecystectomy due to GPs is pseudopolyp or adenoma. In our study, no carcinoma was observed in any patient who underwent surgery for polyps. Further studies are needed to determine the indication for surgery due to GP.
