Endoscopy

Endoscopy and the cohomology of $GL(n)$

Let $G = {rm Res}_{F/mathbb{Q}}(GL_n)$ where $F$ is a number field‎. ‎Let $S^G_{K_f}$ denote an ad`elic locally symmetric space for some level structure $K_f.$ Let ${mathcal M}_{mu,{mathbb C}}$ be an algebraic irreducible representation of $G({mathbb R})$ and we let $widetilde{mathcal{M}}_{mu,{mathbb C}}$ denote the associated sheaf on $S^G_{K_f}.$ The aim of this paper is to classify the data ...

Capsule endoscopy assisted by traditional upper endoscopy.

BACKGROUND AND AIMS Capsule endoscopy (CE) can be prevented by difficulties in swallowing the device and/or its gastric retention. In such cases, endoscopic delivery of the capsule to duodenum is very useful. We describe the indications and outcomes of cases in which traditional endoscopic techniques allowed placement of the capsule in duodenum. PATIENTS AND METHODS This is a retrospective, d...

Ethical aspect in Gastrointestinal Endoscopy in Iran

    Abstract   Background: Gastroenterologists are required to obtain consent before undertaking   any endoscopic examination. Published data indicate that in practice there are many deficiencies in this process. The aim of this survey was to determine the quality of information given to patients before the endoscopic procedures in Iran .   Methods: A structured questionnaire about patient's in...

Photoacoustic endoscopy.

We have developed photoacoustic endoscopy with a miniaturized imaging probe. A light-guiding optical fiber, an ultrasonic sensor, and a mechanical scanning unit are integrated to enable circumferential sector scanning, which produces B-scan images. Biological tissues, including the gastrointestinal tract of a rat, have been imaged ex vivo or in situ.
