Gallbladder polyps: evolving approach to the diagnosis and management.

Area of Science:

• Gastroenterology and Hepatology
• Diagnostic Imaging
• Surgical Oncology

Background:

• Gallbladder (GB) polyps are common mucosal projections, frequently detected via ultrasonography.
• Prevalence ranges from 1.3% to 9.5%, with most polyps being asymptomatic and benign.
• Cholesterol polyps constitute the majority (60-70%) of non-neoplastic GB lesions.

Purpose of the Study:

• To review current concepts regarding the diagnosis of GB polyps.
• To outline the treatment algorithm for GB polyps based on established guidelines.
• To discuss factors influencing clinical management decisions for GB polyps.

Main Methods:

• Literature review of commonly recognized concepts on GB polyp diagnosis and treatment.
• Summary of diagnostic modalities, focusing on ultrasonography findings.
• Analysis of factors influencing the decision for surgical intervention, such as polyp size and patient characteristics.

Main Results:

• Most GB polyps are benign, with cholesterol polyps being the most frequent type.
• Polyps larger than 1 cm are generally recommended for laparoscopic cholecystectomy due to malignant potential.
• Management decisions are influenced by polyp size, shape, number, patient age, and comorbidities like primary sclerosing cholangitis and gallstones.

Conclusions:

• GB polyps are frequently diagnosed, necessitating a clear understanding of their characteristics.
• A size threshold of 1 cm is a key indicator for considering surgical intervention.
• A comprehensive treatment algorithm integrates polyp features and patient risk factors for optimal management.
