Upper gastrointestinal endoscopy
In our practice of gastrointestinal endoscopy we have noticed that the use of internal landmarks to determine the anatomical position of the endoscope tip can be inaccurate. This was especially the case during colonoscopy [1]; sometimes it has been required to spray water through the endoscope channel and watch how it fell because this was the only way to confirm the gravitational vertical direction, which does not necessarily match the upper and lower orientation of the video endoscopy monitor.

An HIV-infected man developed listeriosis six days after an upper gastrointestinal (GI) endoscopy. Although listeriosis has been rarely described following lower GI endoscopy, we believe this is the first case related to upper GI endoscopy.

Introduction: The role of neuro-endoscopy is emerging. Traditional endoscopy is complicated by limited 2D views that make surgical interventions difficult. We have developed a rigid endoscope with a variable direction view that provides 3D visualization. Materials and Methods: A prototype of the EndActive® endoscope was used to examine 2 brain/intraventricular models. A 360-degree view is controlled via integrated joystick. Alternatively, the computer can volumetrically capture the ventricular surface. The captured video image can be viewed later or processed to create a flat projection map. The performance of this endoscope was compared to standard endoscopy with fixed directions of view. To simulate endoscopy, the center of the first brain model had eight labeled projections. The model was inspected with the multidirectional endoscope, standard rigid endoscopes (0-, 30- and 70-degrees), and via a projection map. Ten neurosurgeons proficient in neuro-endoscopy were recruited for the experiments. The second brain model was labeled with 32 intraventricular tumors. Results: With a 0-degree endoscope, only the number directly opposite the site of entry was visualized. With increasing angles, additional numbers were visualized. The 70 -degree endoscope allowed 4 of 8 numbers to be visualized. Using the multidirectional endoscope, all 8 numbers were visualized. The multidirectional endoscope was more accurate in identifying markers compared to standard endoscopy (p = 0.031). The mean endoscopy times using the multidirectional endoscope and standard endoscopy were 143 and 117 seconds, respectively (p = 0.243). The best performance was obtained when the flat projection map was read (p < 0.01). Using the endoscope prototype, an average of 30.8 (96 %) tumors was identified on the brain model. Conclusion: The EndActive® endoscope is a rigid endoscope that provides complete visualization of a 3D space by controlling an adjustable viewing direction. In our study, the multidirectional endoscope provided superior visualization compared to standard endoscopy.

Objective To explore the diagnostic and therapeutic value of early endoscopy in upper gastrointestinal hemorrhage. Methods 143 upper gastrointestinal hemorrhage patients were examined and treated by early endoscopy. Results 141 cases upper gastrointestinal hemorrhage patients were recovered with endoscopy, but 2 cases were of no effect so changed with operation. Conclusion Early endoscopy is a kind of convenient, easy and safe method in diagnosis and treatment of upper gastrointestinal hemorrhage.

Background and Study Aims: Upper gastrointestinal endoscopy is performed without sedation in many countries. Unsedated patients experience more discomfort during endoscopy than sedated patients, but few studies have examined factors which could be modified to minimize discomfort during the procedure. We assessed the effect of endoscope diameter on patient discomfort during unsedated transoral gastroscopy.

Transnasal upper endoscopy has been implemented in the last decade as it is perceived as less fastidious than peroral endoscopy, and small-caliber gastroscopes are widely available in the endoscopic centres. We report the feasibility of performing a full colonic study with ileal intubation, using a small-caliber endoscope commonly used for transanal endoscopy, after failing with a standard gastroscope.

Abstract Background During postoperative follow-up, the visible range of maxillary sinus (MS) is limited, even combining 0° and 70° rigid endoscopes together. Flexible endoscope has been used in larynx examinations for a long time, but rarely in nasal cavity and sinus. We aimed to evaluate the application values of rigid and flexible endoscopes for visualization of MS. Methods We followed up 70 patients with lesions in MS via both rigid and flexible endoscopes. In addition, we used thin-slice CT image of the sinus to create a MS model and divided it into two parts for 3D printing. The inner surface of the 3D-printed sinus was marked with grid papers of the same size (5 mm × 5 mm), then the visual range under rigid endoscopes with different angle and flexible endoscopes was calculated and analyzed. Results In clinical follow-up, we found that flexible endoscopy can reach where rigid endoscopy cannot, which is more sensitive than medical imaging. Endoscopes showed the largest observation range of the posterolateral wall, more than half of which can be visualized by 0° endoscope. Almost all of the posterolateral wall can be revealed under 45° endoscope, 70° endoscope and flexible endoscope. The visual range of each wall under flexible endoscope is generally greater than that under rigid endoscopes, especially of the anterior wall, medial wall and inferior wall. Conclusion There was obviously overall advantage of using flexible endoscope in postoperative follow-up of MS lesions. Flexible endoscopy can expand the range of observation, and improve the early detection of the recurrent lesion. We recommend flexible endoscope as a routine application. Graphical abstract

Diagnostic upper gastrointestinal endoscopy is the most basic of endoscopy procedures and is the technique that trainee doctors first learn. Mastering the basics of endoscopy is very important because when this process is imprecise or performed incorrectly, it can severely affect a patient's health or life. Although there are several guidelines and studies that consider these basics, there are still no standard recommendations for endoscopy in Korea. In this review, basic points, including proper endoscope insertion, precise observation without blind spots, and appropriate photographing, for upper gastrointestinal endoscopy will be discussed.

In a prospective study including 1526 consecutive endoscopies, attempts were made to characterize the benefit of upper gastrointestinal endoscopy. Before endoscopy judgements were made about the most likely diagnosis and treatment and about the degree of suspicion of upper gastrointestinal malignancy. After endoscopy the same types of judgement were made again. The study showed that about half of the endoscopies disclosed clinically significant abnormalities. Furthermore, about every third endoscopy led to unpredicted diagnostic and diagnostic and therapeutic consequences. The benefit was comparably small in patients below the age of 40 years and particularly great in patients above the age of 65, in patients submitted to endoscopy because of barium meal pathology or general suspicion of malignancy, and in patients with upper gastrointestinal bleeding. In general, the present study supports the widespread use of upper gastrointestinal endoscopy in clinical practice.
