Ito et al evaluated patients with polypoid lesions of the gallbladder (PLG) detected on imaging studies. They listed indications for cholecystectomy in these patients. The authors are from Memorial Sloan-Kettering Cancer Center in New York City.


Patient selection: polypoid lesion of gallbladder seen on ultrasound or other imaging study


Indications for cholecystectomy:

(1) patient preference

(2) polyp diameter > 10 mm

(3) presence of abdominal symptoms

(4) can be done along with another operation

(5) rapid increase in size within 4 to 12 months (ratio of followup-to-initial diameter ranged from 1.4 to 4)


A lesion < 6 mm rarely is neoplastic. A lesion that is <= 10 mm in diameter can be safely monitored by imaging studies. Benign lesions show no significant increase in diameter over 1 year.
