Does ROSE matter? Evaluation of final diagnostic, PD-L1 immunohistochemistry, and molecular testing yields of CT-guided lung biopsies performed before and after the onset of the COVID-19 pandemic.

Introduction: The onset of the COVID-19 pandemic, with urgent implementation of safety protocols limiting the number of on-site personnel, essentially terminated the use of rapid on-site evaluation (ROSE) for computed tomography (CT)--guided lung biopsies at our institution. The diminished use of ROSE during the pandemic prompted us to reevaluate the potential value of ROSE for CT-guided lung biopsies.

Materials And Methods: We retrospectively identified all CT-guided lung biopsies from 2017 to 2022.

CT characterization of retractor related liver injuries after pancreaticoduodenectomy: Retrospective analysis of a single institution experience.

Purpose: Retractor related liver injuries (RRLI) are reported after upper gastrointestinal tract surgeries; most commonly laparoscopic cholecystectomy and gastric surgeries. The aim of this study was to characterize the incidence, identification, type, severity, clinical features and risk factors for RRLI after open and robotic pancreaticoduodenectomy.

Methods: A 6-year retrospective study of 230 patients was performed.

Colon cancer metastatic to a urachus diagnosed by PET/CT.

A 50-year-old man presented with a mass in the transverse colon diagnosed by colonoscopy. He underwent a left hemicolectomy and was diagnosed with a moderately differentiated adenocarcinoma penetrating into the pericolic adipose but no lymph node metastases. His course was uneventful with enrollment in a monoclonal antibody research treatment protocol.
