Comparison of microscopic full-laminectomy (open surgery) and microendoscopic minimally invasive hemilaminectomy for thoracic extramedullary spinal tumours.

Background: Minimally invasive treatments for spinal cord tumours are common. The aim of this study was to compare the perioperative outcomes of patients with thoracic extramedullary spinal tumours (TEST) treated by microendoscopic minimally invasive surgery-hemilaminectomy through a homemade tubular retractor (MIS-TR) and microscopic full laminectomy (open surgery).

Methods: Between February 2016 and February 2021, 51 patients with TEST were included.

Multi-center application of a convolutional neural network for preoperative detection of cavernous sinus invasion in pituitary adenomas.

Objective: Cavernous sinus invasion (CSI) plays a pivotal role in determining management in pituitary adenomas. The study aimed to develop a Convolutional Neural Network (CNN) model to diagnose CSI in multiple centers.

Methods: A total of 729 cases were retrospectively obtained in five medical centers with (n = 543) or without CSI (n = 186) from January 2011 to December 2021.
