“…There are two types of contraindications: the absolute and the relatives. Absolute contraindications include the bowel obstruction, extensive and active Crohn's, fistulas and strictures, intestinal pseudo-obstruction, young children examination [28]. The relative contraindications are for patients that have dysphagia, previous abdominal surgery, pregnancy, diverticulosis, cardiac pacemakers, and implanted electro-medical devices [28].…”

“…Absolute contraindications include the bowel obstruction, extensive and active Crohn's, fistulas and strictures, intestinal pseudo-obstruction, young children examination [28]. The relative contraindications are for patients that have dysphagia, previous abdominal surgery, pregnancy, diverticulosis, cardiac pacemakers, and implanted electro-medical devices [28]. The last two contraindications have been excluded from the absolute group since some studies noted no interference between capsule endoscopy and implantable devices functioning [29,30].…”

“…The capsule has a size of a vitamin and it can be easily swallowed, moving naturally through the GI tract until the excretion. This fact indicates a painless procedure, compared to the discomfort offered by the long endoscope of conventional endoscopy [28,31].…”

This paper presents new perspectives of photonic technologies for capsule endoscopy. It is firstly presented a review about conventional endoscopy (upper endoscopy and colonoscopy), followed by capsule endoscopy (CE), as well as their techniques, advantages, and drawbacks. The technologies for CEs presented in this paper have the potential of integration on the existing endoscopic systems commercially available. Such technologies include narrow band imaging (NBI), photodynamic therapy (PDT), confocal laser endomicroscopy (CLE), Optical coherence tomography (OCT) and Spectroscopy in order to improve the performance of the GI tract examination. In the context of NBI, two optical filters were designed and fabricated for integration into endoscopic capsules, allowing the visualization of light centered at the 415 nm and 540 nm. These optical filters are based on the principle of Fabry-Perot and were made of thin-films of titanium dioxide (TiO2) and silicon dioxide (SiO2). Moreover, strategies and aid solutions for the adaptation of ECs for PDT are also discussed.

“…Over the years many researchers have developed RFE platforms focused on various actuation and control approaches. There are several recent reviews (Li et al, 2007;Ciuti et al, 2016;Tapia-Siles et al, 2016;Li and Chiu, 2018;Boskoski and Costamagna, 2019;Ciuti et al, 2020;Visconti et al, 2020) that cover these technologies and other cutting-edge platforms in depth which is not the remit of this paper. A selection of them are listed in Table 1.…”

“…The less invasive a procedure is; the less risk it carries, more so in the current climate. Currently available capsules can visualize the small bowel (such as the PillCam (Li et al, 2007)) and therefore have good diagnostic capabilities but lack therapeutic capabilities. Capsules for upper GI tract are more difficult but some devices with handheld magnetic control have shown some promise, again solely for diagnostic use.…”

Guidelines for Robotic Flexible Endoscopy at the Time of COVID-19

et al. 2021

Flexible endoscopy involves the insertion of a long narrow flexible tube into the body for diagnostic and therapeutic procedures. In the gastrointestinal (GI) tract, flexible endoscopy plays a major role in cancer screening, surveillance, and treatment programs. As a result of gas insufflation during the procedure, both upper and lower GI endoscopy procedures have been classified as aerosol generating by the guidelines issued by the respective societies during the COVID-19 pandemic—although no quantifiable data on aerosol generation currently exists. Due to the risk of COVID-19 transmission to healthcare workers, most societies halted non-emergency and diagnostic procedures during the lockdown. The long-term implications of stoppage in cancer diagnoses and treatment is predicted to lead to a large increase in preventable deaths. Robotics may play a major role in this field by allowing healthcare operators to control the flexible endoscope from a safe distance and pave a path for protecting healthcare workers through minimizing the risk of virus transmission without reducing diagnostic and therapeutic capacities. This review focuses on the needs and challenges associated with the design of robotic flexible endoscopes for use during a pandemic. The authors propose that a few minor changes to existing platforms or considerations for platforms in development could lead to significant benefits for use during infection control scenarios.
