Abstract
BACKGROUND

Metabolic dysfunction-associated steatotic liver disease (MASLD) is highly prevalent worldwide. Experimental studies have shown that cholecystectomy (Chx) increases metabolic dysfunction-associated steatotic liver (MASL) and is associated with MASLD in large retrospective cohort studies.

AIM

To prospectively evaluate the effect of Chx on MASL and fibrosis, assess the prevalence of MASLD, and identify its risk factors in this population.

METHODS

There were 213 MASLD patients enrolled, with 103 being Chx and 110 being non-Chx patients. The patients were followed up for 36 months.

RESULTS

Body mass index increased in the Chx group (30.15 ± 4.08 to 31.58 ± 4.64) vs (31.90 ± 4.07 to 30.03 ± 4.16) in the control group (P < 0.001). Median controlled attenuation parameter increased from 300.77 ± 47.42 to 314.17 ± 44.7 (Chx) and decreased from 325.06 ± 41.74 to 296.36 ± 56.51 (control) (P < 0.01). MASL/magnetic resonance imaging (MRI) moved from 14.22 ± 8.64 and 18.55 ± 8.57 at baseline to 15.98 ± 7.93 and 13.88 ± 8.12 at the end of the study (P < 0.001). The biological scores of MASL (fatty liver index, hepatic steatosis index, and lipid accumulation product) all progressed in the Chx group and regressed in the control group (P < 0.001). The prevalence of hepatic steatosis was 42.38% (Chx). Risk factors associated with significant hepatic steatosis were metabolic syndrome, Chx, MASL/MRI, and fatty liver index scores. Risk factors associated with advanced fibrosis are body mass index, aspartate aminotransferase/alanine aminotransferase ratio, diabetes mellitus score, stiffness, and Chx. Stiffness, obesity, Chx, gamma-glutamyl transferase, and MASL/MRI are associated with metabolic dysfunction-associated steatohepatitis (MASH) lesions.

CONCLUSION

Chx increases MASL and fibrosis. MASLD prevalence in the Chx group is higher than in the overall population.

Core Tip: Metabolic dysfunction-associated steatotic liver disease (MASLD) has emerged as the most common chronic liver disease. It is significantly linked to diabetes, obesity, and other cardiometabolic risk factors. It is more pronounced in cholecystectomized patients than in those with lithiasis. Recent research suggests that the gallbladder may help to maintain overall metabolic homeostasis. Recent data suggests that cholecystectomy (Chx) has metabolic effects and may operate as a risk factor for MASLD and metabolic syndrome. In our study, we found that Chx enhances metabolic dysfunction-associated steatotic liver and fibrosis. MASLD prevalence is higher in the Chx group than in the general population.
