Non-contact Endoscopy at Covid-19 Outbreak

The COVID-19 outbreak and spread throughout the world now constitutes a global public health emergency. Direct contact between doctors and patients in daily practice bears potential risk of Covid-19 infection, and telemedicine, or non-contact medicine, in this circumstance, offers an ideal solution. Remote controlling capsule endoscopy system for gastric examination was recently developed and applicated in clinical practice.

Study Overview

• Status: Completed
• Conditions: Infectious Disease; Gastrointestinal Disease
• Intervention / Treatment: Device: Non-contact MCE system

Detailed Description

The novel non-contact magnetically-controlled capsule endoscopy (MCE) system (Ankon Technologies, China) adds a remote control workstation and a audio-visual exchange system to the original well-establish MCE system, which consists of a robotic magnetic arm, a workstation (now bypassed) and a capsule endoscope, and boasts a 90% sensitivity and 94% specificity for diagnosing gastric focal lesions. This feasibility study aims to evaluate the technical success, clinical success and adverse events of the first clinical application of non-contact MCE system.

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Non-contact MCE examination; Study subject in this arm receives non-contact MCE examination.

Device: Non-contact MCE system; After an overnight fasting and drinking 1000 mL water and simethicone for gastric dilatation and preparation, the study subject positions himself (herself) on the examination bed in Room A, while the operating doctor sits in Room B at the remote control workstation instructing her to swallow the capsule via the audio-visual exchange system. After the capsule entering the stomach, the doctor manipulated the two joysticks on the remote control workstation, mobilizing the robotic magnetic arm, and simultaneously driving the precise movement and rotation of the capsule to perform the gastric examination.
