Semi-automatic robotic puncture system based on deformable soft tissue point cloud registration.
Int J Comput Assist Radiol Surg
October 2024
Article Synopsis
- - The study introduces a semi-automatic robotic puncture system that utilizes real-time ultrasound imaging to address challenges in puncturing deformable soft tissues, like the liver, which are affected by respiratory movement.
- - This system constructs a 3D point cloud of the target tissue by combining ultrasound data and CT images, enabling quick and precise positioning for needle insertion, with an operation time of approximately 64.5 seconds and a needle accuracy error of about 0.8 mm in trials.
- - Results from phantom experiments and animal surgeries show a 100% success rate for the puncture robot system, emphasizing its high accuracy and efficiency for clinical applications in liver tissue puncture surgeries.
Coral polyps are composed of four tissues; however, their characteristics are largely unexplored. Here we report biological characteristics of tentacles (Te), mesenterial filaments (Me), body wall (Bo), and mouth with pharynx (MP), using comparative genomic, morpho-histological, and transcriptomic analyses of the large-polyp coral, Fimbriaphyllia ancora. A draft F.

Methods: Altogether, 136 patients diagnosed with achalasia by high-resolution manometry (HRM) were enrolled.
A prediction model of abnormal acid reflux in gastroesophageal reflux disease.
J Gastroenterol Hepatol
September 2024
Background And Aim: The measurement of esophageal acid exposure time (AET) using combined multichannel intraluminal impedance-pH (MII-pH) tests is the gold standard for diagnosing gastroesophageal reflux disease (GERD). However, this catheter-based 24-h test can cause considerable patient discomfort. Our aim is to identify factors affecting AET and to develop a scoring model for predicting AET abnormalities before conducting the MII-pH test.
View Article and Find Full Text PDFBackground: Vonoprazan, a potassium-competitive acid blocker, demonstrates more potent acid inhibition than proton pump inhibitors (PPIs). This study aimed to evaluate the effect of vonoprazan in patients with unproven gastroesophageal reflux disease (GERD) by comparing patients with vonoprazan-refractory heartburn with those with PPI-refractory heartburn.
Methods: This study included 104 consecutive patients with vonoprazan- or PPI-refractory heartburn (52 patients each), no erosive esophagitis on endoscopy and who underwent combined multichannel intraluminal impedance-pH (MII-pH) testing with vonoprazan/PPI discontinuation.
