Methods: This single-center, retrospective study included 202 patients aged >80 years with AC without common bile duct (CBD) stones who underwent PTGBD between January 2010 and December 2019.

Results: One hundred and forty-two patients underwent elective laparoscopic cholecystectomy (ELC), and 60 underwent conservative treatment, specifically PTGBD removal (PTGBD-R) in 36 patients and PTGBD maintained (PTGBD-M) in 24 patients.

Efficacy of sentinel lymph node biopsy with radioisotope alone and the prediction of sentinel node status using PET-CT in breast cancer.

Purpose: Sentinel lymph node biopsy (SLNB) using both a radioactive isotope (RI) and blue dye is considered highly effective; however, there were limitations with the use of both agents in some hospitals, and blue dye has been shown to have some adverse effects. Additionally, preoperative prediction of sentinel lymph node (SLN) status using the maximum standardized uptake value (SUVmax) on positron emission tomography-computed tomography (PET-CT) can help avoid unnecessary axillary dissection or SLNB. Thus, we evaluated the efficacy and oncologic safety of SLNB using an RI alone in terms of long-term outcomes and determined the association between SLN metastasis and SUVmax of the primary tumor.
