An extraperitoneal single-port robotic approach to low anterior resection-Cadaveric experience.

Aim: A minimally invasive surgery (MIS) extraperitoneal (XP) approach to left-sided colorectal resection utilizing the laparoscopic approach has recently been shown to be safe and feasible and to have potential advantages over the transperitoneal approach, especially in high-risk surgical patients. The aim of this article is to provide a first cadaveric demonstration of the use of a single-port robotic platform in performing XP low anterior resection by MIS.

Method: A single-port robotic platform (DaVinci®SP™) was used to perform XP single-port low anterior resection in two cadavers with body mass indexes (BMIs) of 19 and 40 kg/m.

Metastatic Salivary Duct Carcinoma with ERBB2 Amplification and Sequential Response to Ado-Trastuzumab Emtansine and Neratinib: A Case Report.

Introduction: Salivary duct carcinoma (SDC) is an aggressive and rare subtype of salivary gland carcinoma. Surgical excision and radiotherapy are standard of care for early cancer. Chemotherapies with taxanes and platinum show overall response rates between 39% and 50%.

A third of the radiotracer dose: two decades of progress in pediatric [F]fluorodeoxyglucose PET/CT and PET/MR imaging.

Objectives: To assess the evolution of administered radiotracer activity for F-18-fluorodeoxyglucose (18F-FDG) PET/CT or PET/MR in pediatric patients (0-16 years) between years 2000 and 2021.

Methods: Pediatric patients (≤ 16 years) referred for 18F-FDG PET/CT or PET/MR imaging of the body during 2000 and 2021 were retrospectively included. The amount of administered radiotracer activity in megabecquerel (MBq) was recorded, and signal-to-noise ratio (SNR) was measured in the right liver lobe with a 4 cm volume of interest as an indicator for objective image quality.

Bone SPECT/CT in Advanced Diffuse Tenosynovial Giant Cell Tumor of the Wrist.

Tenosynovial giant cell tumor, previously known as pigmented villonodular synovitis, is a benign low-grade fibrohistiocytic proliferation with hemosiderin deposits in synovial joints. Mostly affecting the knee, it can also manifest in other synovial joints, infrequently also in the wrist. Tenosynovial giant cell tumor typically causes intense radionuclide uptake in all phases in planar bone scintigraphy, making a differentiation from other bone tumors or osteomyelitis difficult, especially in cases associated with extensive bone destruction.
