Gif q260

H pylori infection was detected with a biopsy urease test (CLO test, Pronto Dry, Gastrex, Poland) using standard EGD with gastrofiberscopes (GIFQ260, Olympus Optical, Tokyo Japan). A specimen for biopsy urease testing of each subject was taken from the gastric antrum using biopsy forceps and assessed within 60 minutes. The agar color turned from yellow to red when the biopsy specimen was infected by H pylori, which expresses an intracytoplasmic urease.

All EGDs were performed at the Health Evaluation Center. Some people had gastrointestinal discomfort, but most of the others did not show any discomfort clinically. The definition of having GERD was determined by EGDs findings, rather than being defined by the symptoms of clinically presenting GERD. Four experienced gastroenterologists blinded to the study aimed to perform the EGD using gastrofiberscopes (GIFQ260, Olympus Optical, Tokyo, Japan). The severity of GERD was graded from A to D according to the Los Angeles Classification.
Grade A: One (or more) mucosal break, no longer than 5 mm that does not extend between the tops of two mucosal folds.
Grade B: One (or more) mucosal break, more than 5 mm long that does not extend between the tops of two mucosal folds.
Grade C: One (or more) mucosal break that is continuous between the tops of two or more mucosal folds but involves less than 75% of the circumference.
Grade D: One (or more) mucosal break involving at least 75% of the esophageal circumference.

After fasting for 4 to 6 h, each patient underwent an upper endoscopy under local pharyngeal anesthesia with Lidocaine mucilage. Flexible endoscopes (GIF-Q240, GIF-Q260, GIF-H260, GIF-H290; Olympus Optical Co, Ltd., Tokyo, Japan) were used for the procedure. A variety of accessory devices were used to remove the FBs, which included foreign-body retrieval forceps, retrieval baskets and snares. A latex protector hood was used to protect the digestive tract while removing FBs.

All patients suspected of having ingested foreign bodies underwent routine radiologic and laryngologic examination to exclude oropharyngeal foreign bodies. Patients also underwent computed tomography scan of the chest, depending on the clinical setting and at the discretion of the attending physician, before or after the endoscopic procedure. Endoscopic foreign body removal was initially attempted using a flexible endoscope (GIF-H260 or GIF-Q260; Olympus Optical Co., Ltd., Tokyo, Japan). All patients were examined by board-certified endoscopists under local pharyngeal anesthesia with lidocaine. Because of the risk of aspiration, patients were not placed under conscious sedation. Vital signs, including blood pressure, heart rate, and oxygen saturation, were monitored continually throughout the procedure. Accessory devices used to remove foreign bodies included standard biopsy forceps, rat-tooth forceps, alligator forceps (FG-47 L-1; Olympus), a retrieval basket (MTW Endoskopie, Wesel, Germany), or a snare (MTW Endoskopie). Additional protective measures, such as a latex protector hood (DIAGMED, Thirsk, England), an overtube (TS-12,140 or TS-13,140; Fujinon, Saitama, Japan), or a transparent cap (Olympus), were occasionally used to prevent damage to the gastrointestinal tract during the removal of sharp or pointed foreign bodies.
