Measuring Gastric Juice pH and Endoscopic Screening

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

A high-resolution magnifying upper GI endoscope (GIF-Q240Z; Olympus Co. Ltd., Tokyo, Japan) or a high-definition magnifying upper GI endoscope (GIF-H260Z; Olympus Co. Ltd., Tokyo, Japan) and an electronic endoscopy system (EVIS LUCERA Spectrum; Olympus Co. Ltd., Tokyo, Japan) were used. Measurement of the fasting gastric juice pH and endoscopic examinations were carried out by specialists certified by the Japan Gastroenterological Endoscopy Society. Endoscopic studies were performed following an overnight fast of >12 h.
To prevent contamination from affecting the accuracy of the pH measurements, premedication (such as a mucolytic or deforming agent) was not administered, except for local pharyngeal anesthesia with an 8% lidocaine pump spray. After the endoscope had been inserted into the stomach, pooled gastric juice was aspirated and collected endoscopically according to a previously described technique [11 (link)]. The pH of the collected sample was immediately measured using a 14-step pH test strip (pH 1-14; AS ONE Co. Ltd, Osaka, Japan). Following this, the observer performed a routine screening endoscopy study by high-resolution white light electronic endoscopy. The endoscopic photos and the results were recorded in a digital filing system (NEXUS; Fuji Film Medical Co., Tokyo, Japan).

Endoscopic Observation of Cellular Structure

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

We used the prototype of ECS (GIF-Y0002; Olympus Corporation, Tokyo, Japan) connected to a video-endoscopy system (CV260, EVIS LUCERA SPECTRUM; Olympus). The GIF-Y0002 is an integrated type of endoscope with one lens that enables a progressive increase in magnification to ×380 (tissue field of view, 700 µm × 600 µm, 0.42 mm²) using a hand lever. Up to ×600 ultra-high magnification is available when the electronic zoom function (×1.6) is activated by pushing the button [24 (link)]. The consecutive zoom function allows us to find the target area through non-magnifying observation, while maintaining the center of the endoscopic view. The ECS system can visualize not only the gland duct lumens and villi, but also the shape of epithelial cells and nuclei at a focus depth of about 50 µm.

Magnifying Endoscopy for Gastric Neoplasia Assessment

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

The instruments used in the current study were a high-resolution magnifying upper gastrointestinal endoscope (GIF-Q240Z;Olympus Medical Systems, Tokyo, Japan) or a high-definition magnifying upper gastrointestinal endoscope (GIF-H260Z; Olympus Medical systems, Tokyo, Japan) and an electronic endoscopy system (EVIS LUCERA Spectrum; Olympus Medical Systems). A soft black hood (MAJ-1988 for the GIF-Q240Z, MAJ-1989 for the GIF-H260Z; Olympus) was mounted at the tip of the endoscope to enable the endoscopist to fix a consistent focal distance between the tip of the endoscope and the gastric mucosa. M-NBI examinations and the recording of endoscopic findings were carried out by four endoscopists ( T. U., K. T, Y. Y, and M. F.). The presence or absence of WOS was determined in each of the neoplasias based on the findings of M-NBI. Neoplasias with a partially positive WOS were considered “WOS positive”. For assesment of the background gastric mucosa, atrophy was graded endoscopically according to the Kimura and Takemoto classification 11 .

Endoscopic Resection Techniques for GI Lesions

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

ER was defined as endoscopic mucosal resection with a cap-fitted panendoscope (EMRC) and ESD. The decision to resect with ESD or EMRC depended on the size of the lesion, and the final decision was made by the endoscopist.
The video processor unit EVIS LUCERA SPECTRUM, EVIS LUCERA ELITE, or EVIS X1 (Olympus Corporation, Tokyo, Japan) and a single-channel upper gastrointestinal endoscope (GIF-Q260J, GIF-H290T; Olympus Co.) were used.
For ESD, hyaluronic acid (MucoUP; Boston Scientific, Tokyo, Japan or Ksmart; Olympus Co.) was used for submucosal injection. A DualKnife (KD-655Q or KD-655L, Olympus Co.), IT-nano knife (KD-612L, Olympus Co.), and Splash M-knife (Pentax Medical, Japan) were used for submucosal dissection.
For EMRC, snare (SD-221L-25, Olympus Co) was used for resection.

Microvessel Pattern Classification in Endoscopy

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

The instruments used in our study were an electronic endoscopic system (EVIS LUCERA Spectrum; Olympus, Tokyo, Japan) and a high resolution magnifying video endoscope (GIF-H260Z and GIF-H290Z, Olympus, Tokyo, Japan). A soft hood was mounted at the tip of the endoscope to obtain a clear view for ME-NBI. Microvessel patterns were classified into intralobular loop pattern (ILL), fine network patten (FNP), and corkscrew patten (CSP) according to previous studies [9 (link), 12 , 13 (link)]. If more than one pattern were observed in the lesion, the lesion was classified based on the predominant vascular pattern.

Endoscopic Screening Protocols Comparison

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

In the EUS group, all EGDs were performed immediately before EUS in the same session by EUS operators. In principle, screening EGD was performed in patients who had not undergone EGD at our hospital within approximately 1 year; additionally, screening EGD was performed if the attending physician deemed it necessary. EGD and EUS were performed under sedation with 0.1–0.5 mg of flunitrazepam and 17.5–35 mg of pethidine hydrochloride. The GIF-H260, H260Z, Q260, Q260, H290, or H290Z (Olympus Co., Japan) video endoscopy system (Evis Lucera Spectrum or Evis Lucera Elite; Olympus Co., Japan) was used for screening EGD at random. In contrast, in the MCC group, EGD was primarily performed by expert operators who were familiar with screening. The EG-L580NW7 (FujiFilm Co., Japan) and video endoscopy systems (LASEREO 7000 System; FujiFilm Co., Japan) were used for screening EGD. Magnification endoscopy or sedation was not used at the MCC. In both groups, image enhancement endoscopy (IEE) was used in all cases for esophageal observation, and as needed in other cases. Indigo carmine was not used for screening in our hospital.

Magnifying Endoscopic Evaluation of Gastric Mucosa

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

A single endoscopist (KY) with 15 years of experience with magnifying gastroscopy performed all endoscopic diagnostic procedures. The instruments used in the procedures were high-resolution magnifying upper gastrointestinal endoscopes (GIF-Q240Z or GIF-H290Z; Olympus, Tokyo, Japan) and an endoscopy system (EVIS LUCERA SPECTRUM; Olympus). In addition, a black soft hood (MAJ 1989; Olympus) was mounted at the tip of the scope in order to consistently fix the focal distance between the tip of the scope and the mucosal surface during magnifying observation at the maximal magnification rate. At 30 minutes prior to the endoscopic examination, patients drank 100 mL of a preparation solution that contained 10,000 units of pronase (Kaken Pharmaceutical, Tokyo, Japan), 1 g of sodium bicarbonate, and 10 mL of dimethylpolysiloxane (20 mg/mL; Horii Pharmaceutical Ind., Osaka, Japan). After inserting the endoscope, all of the gastric mucosa was inspected according to the systematic screening protocol for the stomach (SSS) [4 (link)]. When the SSS was completed, detected mucosal lesions were observed by conventional white-light imaging, non-magnifying narrow-band imaging (N-NBI), and magnifying narrow-band imaging (M-NBI) at the maximum magnification rate. All endoscopic images were recorded in an image filing system. A target biopsy was taken from the MWFL.

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.
