Comparison of Motility between the Sphincter of Oddi and the Duodenum in Percutaneous Transhepatic Manometry of the Sphincter of Oddi
"배경 및 목적: 동물실험에서 Oddi 괄약근 운동성이 시간의 경과에 따라 주기적인 변화를 보이며, 이러한 주기적인 변화가 소장의 migrating motor complex (MMC)의 주기와 밀접한 연관성이 있다고 보고된 바 있다. 본 연구는 인체에서 경피적 경로를 통한 장기간의 Oddi 괄약근 내압 검사를 시행함으로써 Oddi 괄약근의 주기적 운동성을 포함하는 전체적인 운동성에 대해 살펴봄과 동시에 Oddi 괄약근의 주기적 운동성을 MMC의 각 단계로 나누어 보고, 십이지장의 MMC와의 관련성에 대해서도 알아보고자 하였다. …

Studies of Loop Ileostomy Morbidity and the Potential Benefits of Chyme Reinfusion
… of terminal ileal motility as assessed by manometry. A manometry sub-study investigated the impact of chyme reinfusion on terminal ileal motility. RESULTS: Eight clinical variables were significantly associated with dehydration-related readmissions after ileostomy formation. High rates of …

Risk and pathogenesis of dysphagia related to antireflux surgery
… Objective data were gathered using: i) luminal manometry alone; ii) impedance combined with manometry, to assess relationships between oesophageal pressure and bolus flow; and iii) three-dimensional pressure recordings of expiratory and inspiratory radial OGJ pressure to assess the contribution …

Hydrogen Cryosorption of Micro-Structured Carbon Materials
… In this study, a differential pressure based manometry system was designed and constructed for fast analysing hydrogen adsorption uptakes of sorbents up to a maximum of 10 wt% at 77 K and up to 11 bar. The safety design of the system in compliance with European ATEX directives (Zone 2) for …

Intragastric Mechanical Systems for Dysmotility Diagnosis and Obesity Treatment
… on gastric emptying rate. While high-resolution manometry is used to evaluate motility in narrow tubular organs, such as the esophagus and rectum, there is no analogous system for gastric motility evaluation. To address this, I have developed a motility mapping platform capable of 3D pressure …

Development and validation of a gastroenterology probe capable of measuring the position of the squamo-columnar junction
… position of the squamocolumnar junction to manometry and pH-metry catheters. The accuracy of the measurement was at most 5 millimetres, often better; a better resolution than either the high resolution manometer or custom pH device. The device was validated in-vivo, demonstrating a …

Ocular biomechanics of the anterior segment
… enucleated porcine eyes across a wide range of manometry internal ocular pressure (MIOP). The dynamic E-Modulus was found to be most affected by MIOP change. To investigate the in vivo distribution and heterogeneity of the corneal biomechanics, a novel set-up allowed the mapping of corneal …

Ruolo dello studio manometrico esofageo in pazienti affetti da tireopatia
I pazienti affetti da patologie tiroidee possono sviluppare varie forme di disfagia, sebbene diversi sono gli approcci per lo studio della problematica disfagica, la patologia tiroidea rende tali percorsi diagnostici poco codificati. Abbiamo selezionato mediante questionario swal-qol i pazienti che …

Non-invasive Assessment of Swallowing and Phonation using High-density Electromyography
… modalities including videofluoroscopy, manometry, and endoscopy. This established that the audio-based functional fiducial accurately correlated with manometric data of oropharyngeal swallow onset, allowing subsequent sEMG investigations to non-invasively align with functional onset. The …

RoSE Enhancement for In Vitro Simulations of Human Swallowing
