Determining the extent of cholecystectomy using intraoperative specimen ultrasonography in patients with suspected early gallbladder cancer

摘要

Accumulating evidence and guidelines recommend extended cholecystectomy for T1b or greater gallbladder cancers. This study aimed to evaluate the feasibility of intraoperative ultrasonography of a resected gallbladder specimen (specimen US) for the determination of the extent of cholecystectomy.
