This prototype endocytoscope can consecutively increase the image magnification up to 380-fold (on a 19-inch monitor) with a hand lever, which covers a 700 × 600 μm area of tissue and the light focusing depth ranges from 0 to 50 μm. Using digital 1.6-fold magnification, the magnifying capability is up to 600-fold magnification (on a 19-inch monitor), covering a 440 × 380 μm area.

The endoscopy system used in the prospective trial consisted of a video processor (CV-260SL; Olympus Medical Systems, Tokyo, Japan) and a light source (CLV-260SL; Olympus Medical Systems) that worked in both the high resolution WLE and NBI modes. NBI uses narrow-band short-wavelength light (400 – 430 and 525 – 555 nm) to contrast vascular architecture and surface structure of the superficial mucosa 4 (link). Zoom videogastroscopy that can achieve a maximum of 80-fold optical magnification was used (GIF-Q240Z, GIF-H260Z and GIF-FQ260Z; Olympus Medical Systems). A soft black hood (MB162 or MB46; Olympus Medical Systems) was attached to the tip of the endoscope. The structure enhancement of the endoscopic video processor was set to B-mode level 4 or 6 for WLE and to B-mode level 8 for magnifying NBI. The color mode was set to level 1.

. Magnifying endoscopy that can achieve a maximum 80-fold optical magnification was used (GIF-Q240Z, GIF-H260Z, and GIF-FQ260Z; Olympus Co.). A soft black hood (MB162 or MB46; Olympus Co.) was attached to the tip of the endoscope to enable the endoscopist to maintain an adequate distance for maximal magnification of the endoscopic image. The structural enhancement of the endoscopic video processor was set to B-mode level 4 or 6 for white-light endoscopy and to B-mode level 8 for M-NBI. The color mode was set at level 1.

Colonoscopy Under Deep Sedation

Check if the same lab product or an alternative is used in the 5 most similar protocols

All colonoscopies were scheduled between 8:00 AM and 11:00 AM. Patients received midazolam (0.01-0.02 mg/kg), remifentanil (0.4 μg/kg), and propofol (1-2 mg/kg) intravenously to induce anesthesia. The patients were given nasal oxygen supplementation with a flow rate of 3 L/min. Patients were lying in a left lateral decubitus position during colonoscopy and maintained in deep sedation with a Ramsay sedation score of 4 or greater. The blood pressure, heart rate, and oxygen saturation of patients were monitored using a multifunctional monitoring system. All colonoscopies were performed using CLV-260SL (Olympus Medical Systems, Tokyo, Japan) and the Fujinon 4400 electronic video endoscope system (Fujinon Corporation, Tokyo, Japan). Upon completion of the colonoscopy, the patients were taken to a resuscitation room and were not allowed to leave until they had fully recovered from sedation. All patients were advised to consume liquid food at a low temperature, two hours after the procedure.

Endoscopic Evaluation of Subepithelial Lesions

Check if the same lab product or an alternative is used in the 5 most similar protocols

The video endoscopy system used was the EVIS-LUCERA SPECTRUM system (Olympus, Tokyo, Japan),
which consisted of a light source (CLV-260SL), a processor (CV-260SL), and a magnifying video
endoscope (GIF-H260Z). To obtain a clear view for ME-NBI, a soft hood (MB-46; Olympus) was
fitted on the distal tip of the endoscope to maintain the focal distance. ME-NBI was performed
by a single experienced endoscopist (GHK) who had previously performed more than 100 ME-NBI
examinations. All examinations were performed under conscious sedation with 2 to 5 mg of midazolam. During conventional endoscopy for subepithelial lesions, the following endoscopic features were prospectively recorded for all lesions: (1) location; (2) macroscopic shape (Yamada classification
6 (link)
); and (3) presence of central dimpling, umbilication, or opening on the surface. Subsequently, ME-NBI was performed; during ME-NBI, presence of a microscopic opening on the surface, the status of microsurface structure, and presence of a thickened submucosal vessel were prospectively evaluated (
Fig. 1).

EBUS-GS was performed using a dedicated endobronchial ultrasonography instrument [Xenon light source: CLV-260SL; endoscopic ultrasound system: EU-ME1; cavity ultrasound probe: UM-S20-17S; UM-S20-20R, Olympus (Olympus Sales Service Co., Ltd., Beijin, China)] after 8 h of fasting. Patients were routinely given glottic local anesthesia with 2% lidocaine.^{4 (link)} General anesthesia was performed for patients who could not tolerate local anesthesia.^{5 (link)} An endoscope was inserted through the nasal cavity or mouth. When lesions were detected, tissues were collected by negative pressure suction (the 20 ml volume negative pressure syringe tube was attached to the back end of the guide sheaths and tissues were collected by negative pressure). CT-TTNA was performed with a SIEMENS 64-slice spiral CT [SOMATOM Definition AS, Siemens Co., Ltd. (Beijing, China)]. Patients received a subcutaneous injection of 2% lidocaine as local anesthesia. After locating the lesions with CT, tissues were obtained via core needle biopsy under negative pressure. Patients in the CT-TTNA group were routinely biopsied with an 80 mm needle; if the lesion from the chest wall was >80 mm but ⩽100 mm, a 100 mm needle was used for biopsy operation.

The procedure was performed using an endoscope (GIF-H260Z or GIF-H290Z; Olympus Co., Tokyo, Japan). The endoscopy system consisted of a video processor (CV-260SL or CV-290; Olympus) and a light source (CLV-260SL or CLV-290SL; Olympus) that worked in both the high-resolution WLI and NBI modes. A soft black hood (MAJ-1989 or MAJ-1990; Olympus) was mounted on the tip of the endoscope to enable the endoscopist to maintain a consistent distance between the tip of the endoscope and the mucosal surface to obtain in-focus endoscopic images at maximal magnification. Structural enhancement of the endoscopic video processor was set to B-mode level 4 – 6 for white-light endoscopy and to B-mode level 8 for M-NBI. The color mode was set at level 1.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
