Abstract
BACKGROUND Gastrointestinal (GI) endoscopy is one of healthcare's main contributors to climate change. We aimed to assess healthcare professionals' attitudes and the perceived barriers to implementation of sustainable GI endoscopy. METHODS The LEAFGREEN web-based survey was a cross-sectional study conducted by the European Society of Gastrointestinal Endoscopy (ESGE) Green Endoscopy Working Group. The questionnaire comprised 39 questions divided into five sections (respondent demographics; climate change and sustainability beliefs; waste and resource management; single-use endoscopes and accessories; education and research). The survey was available via email to all active members of the ESGE and the European Society of Gastroenterology and Endoscopy Nurses and Associates (ESGENA) in March 2023. RESULTS 407 respondents participated in the survey (11% response rate). Most participants (86%) agreed climate change is real and anthropogenic, but one-third did not consider GI endoscopy to be a significant contributor to climate change. Improvement in the appropriateness of endoscopic procedures (41%) and reduction in single-use accessories (34%) were considered the most important strategies to reduce the environmental impact of GI endoscopy. Respondents deemed lack of institutional support and knowledge from staff to be the main barriers to sustainable endoscopy. Strategies to reduce unnecessary GI endoscopic procedures and comparative studies of single-use versus reusable accessories were identified as research priorities. CONCLUSIONS In this survey, ESGE and ESGENA members acknowledge climate change as a major threat to humanity. Further improvement in sustainability beliefs and professional attitudes, reduction in inappropriate GI endoscopy, and rational use of single-use accessories and endoscopes are critically required.

Abstract
Third-space endoscopy (TSE) is a subspecialty in interventional endoscopy that exploits the submucosa as a working space for the management of various gastrointestinal diseases. Over recent years, TSE has emerged as a viable alternative to surgery for the treatment of various conditions. The rapid dissemination and adoption of TSE has been largely supported by the advent of novel devices aimed to improve the efficacy and safety of these procedures. In this article, we review some of the recent developments in TSE devices and provide our initial experience with these instruments in clinical practice.

Abstract
Reprocessing of gastrointestinal (GI) endoscopes and accessories is an essential part of patient safety and quality control in GI endoscopy centers. However, current endoscopic reprocessing guidelines or procedures are not adequate to ensure patient-safe endoscopy. Approximately 5.4 % of the clinically used duodenoscopes remain contaminated with high-concern microorganisms. Thus, the Digestive Endoscopy Society of Taiwan (DEST) sets standards for the reprocessing of GI endoscopes and accessories in endoscopy centers. DEST organized a task force working group using the guideline-revision process. These guidelines contain principles and instructions of step-by-step for endoscope reprocessing. The updated guidelines were established after a thorough review of the existing global and local guidelines, systematic reviews, and health technology assessments of clinical effectiveness. This guideline aims to provide detailed recommendations for endoscope reprocessing to ensure adequate quality control in endoscopy centers.

Abstract
This ESGE Position Statement provides structured and evidence-based guidance on the essential requirements and processes involved in training in basic gastrointestinal (GI) endoscopic procedures. The document outlines definitions; competencies required, and means to their assessment and maintenance; the structure and requirements of training programs; patient safety and medicolegal issues. 1: ESGE and ESGENA define basic endoscopic procedures as those procedures that are commonly indicated, generally accessible, and expected to be mastered (technically and cognitively) by the end of any core training program in gastrointestinal endoscopy. 2: ESGE and ESGENA consider the following as basic endoscopic procedures: diagnostic upper and lower GI endoscopy, as well as a limited range of interventions such as: tissue acquisition via cold biopsy forceps, polypectomy for lesions ≤ 10 mm, hemostasis techniques, enteral feeding tube placement, foreign body retrieval, dilation of simple esophageal strictures, and India ink tattooing of lesion location. 3: ESGE and ESGENA recommend that training in GI endoscopy should be subject to stringent formal requirements that ensure all ESGE key performance indicators (KPIs) are met. 4: Training in basic endoscopic procedures is a complex process and includes the development and acquisition of cognitive, technical/motor, and integrative skills. Therefore, ESGE and ESGENA recommend the use of validated tools to track the development of skills and assess competence. 5: ESGE and ESGENA recommend incorporating a multimodal approach to evaluating competence in basic GI endoscopic procedures, including procedural thresholds and the measurement and documentation of established ESGE KPIs. 7: ESGE and ESGENA recommend the continuous monitoring of ESGE KPIs during GI endoscopy training to ensure the trainee's maintenance of competence. 9: ESGE and ESGENA recommend that GI endoscopy training units fulfil the ESGE KPIs for endoscopy units and, furthermore, be capable of providing the dedicated personnel, infrastructure, and sufficient case volume required for successful training within a structured training program. 10: ESGE and ESGENA recommend that trainers in basic GI endoscopic procedures should be endoscopists with formal educational training in the teaching of endoscopy, which allows them to successfully and safely teach trainees.

Abstract
Contamination due to failures or omissions in the reprocessing steps of gastrointestinal endoscopes is common in clinical practice. Ensuring the proper execution of each step is a challenge for reprocessing personnel. This cross-sectional study was conducted in an endoscopy setting between March and May 2021. We performed interviews about reprocessing practices, analyzed the life history of the equipment, and performed inspections through a borescope video of gastrointestinal endoscope channels that were stored and ready for use. A borescope is a complementary tool used to validate endoscope reprocessing, evaluate the internal visualization of channels, and identify changes that can compromise the safety of its use, which are often not detected in the leak test. Thirteen biopsy channels from stored gastrointestinal endoscopes were inspected. We found that 85% had stains and grooves, 69% contained moisture, and 46% had debris. There was at least one noncompliance issue in all of the channels inspected.

Abstract
An 83-year-old male with a history of Whipple procedure (pancreatoduodenectomy) due to pancreatic cancer, underwent endoscopic retrograde colangiopancreatography (ERCP) for acute cholangitis. Because of the altered anatomy, an upper gastrointestinal endoscope was used. Severe stricture of the hepaticojejunal anastomosis was found. The anastomotic stricture was dilated with a 12mm through-the-scope (TTS) balloon under fluoroscopy and direct visualization. Right and left ducts were explored with Dormia basket and balloon, with extraction of bile duct stones and pus. Cholangioscopy with upper gastrointestinal endoscope was performed and residual cholesterol stones were identified in branches of the left hepatic duct and these were removed with the stone extraction balloon under endoscopic visualization. Ciprofloxacin was administered for 5 days and post interventional course was uneventful. Direct peroral colangioscopy using a conventional endoscope provides high quality endoscopic imaging, enabling access to virtual chromoendoscopy and the 2.8 mm diameter working channel allows for interventional procedures. This strategy is useful and economical, helping confirm clearance of common bile duct stones, while allowing extraction of any residual stones. New, cost effective scopes for peroral cholangioscopy are needed to improve the safety and success rate.

Abstract
BACKGROUND Semicritical medical devices are defined as items that come into contact with mucous membranes or nonintact skin (e.g., gastrointestinal endoscopes, endocavitary probes). Such medical devices require minimally high-level disinfection. METHODS Analyze the methods used to reprocess semicritical medical devices and identify methods and new technologies to reduce the risk of infection. RESULTS The reprocessing methods for semicritical medical devices is described as well as a shift from high-level disinfection to sterilization for lumened endoscopes. CONCLUSIONS Strict adherence to current guidelines and transition to sterilization for endoscopes is required as more outbreaks have been linked to inadequately disinfected endoscopes and other semicritical items than any other reusable medical devices.

Abstract
Chronic pancreatitis (CP) is an ongoing inflammatory disease with most patients developing pancreatic calculi during their course of disease. Extracorporeal shock wave lithotripsy (ESWL) is a first-line treatment option in patients with large lumen obstructing pancreatic duct (PD) stones. In patients with CP and PD dilatation, digital single-operator pancreatoscopy (DSOP)-guided lithotripsy seems to be an appealing option to ESWL and surgery. DSOP-guided lithotripsy for the treatment of large symptomatic PD-stones has been demonstrated to be safe, technically, and clinically effective, and should be regarded as an alternative endoscopic treatment of certain patients.

Abstract
Stone clearance with extracorporeal shock wave lithotripsy is a safe and effective procedure for large pancreatic calculi not extractable by the standard endoscopic retrograde cholangiopancreatography techniques. In properly selected patients, this minimally invasive approach should be offered as the first line of therapy instead of surgery. Complete stone clearance can be achieved in three-fourths with long-term pain relief in two-thirds of patients. Re-intervention is required in less than half of the patients. Future studies should compare the extracorporeal approach with intraductal lithotripsy using the pancreatoscope.

Abstract
Rationale: Pancreatic cancer, comprising mostly pancreatic ductal adenocarcinoma (PDAC), is a highly malignant disease, typically known as a hypoxic tumor microenvironment. The application of PDT in pancreatic cancer in clinic is still hampered by several shortcomings, including the (i) deep location of pancreatic cancer, (ii) tissue damage induced by optical fibers, (iii) hypoxic microenvironment, (iv) short excitation wavelengths of traditional photosensitizers, and (v) poor delivery efficiency of photosensitizers. Methods: We designed an organic nanoparticle as photosensitizer for near-infrared II (NIR-II) fluorescent (FL) imaging that exerts a type I PDT effect on deep orthotopic pancreatic tumors under excitation by a NIR (808 nm) laser. Results: This novel photosensitizer exhibits enhanced accumulation in orthotopic pancreatic cancer in mice and could be used to effectively detect pancreatic cancer and guide subsequent laser irradiation for accurate PDT of deep pancreatic cancer. In addition, we built an endoscopic platform monitored by NIR-II FL imaging to achieve minimally invasive endoscopically guided interventional photodynamic therapy (EG-iPDT) with efficient inhibition of orthotopic pancreatic cancer, which prolonged overall survival up to 78 days compared to PBS + EG-iPDT group (*p < 0.05) in a mouse model. Conclusions: Minimally invasive EG-iPDT has promise as an intraoperative treatment for early-stage or unresectable or metastatic pancreatic cancer.

Abstract
INTRODUCTION Previous studies suggest that unmeasured organizational factors drive variability in anesthesia-assisted sedation (AA) use. METHODS A mixed-methods study of 11 Veterans Health Administration and community gastrointestinal endoscopy sites; qualitative interviews of key sedation decision-makers. RESULTS Three key interview themes were identified: (i) Increased AA demand and changes in endoscopist sedation training in fellowship drove site-level AA capacity expansion; (ii) this expansion further influenced sedation decisions in favor of AA use; and (iii) additional organizational factors influencing AA use included site-level decision-making processes and differences between Veterans Health Administration and community practice economics/mission. DISCUSSION Key organizational factors drive variability in AA use across settings.

Abstract
Endoscopy-related pathogen transmission may occur if microorganisms are spread from patient to patient by contaminated equipment. Effective and safe endoscope reprocessing includes bedside precleaning, mechanical cleaning, high-level disinfection, storage, and drying. The aim of this research study was to observe and report on the variation in practice regarding the use of detergent for bedside precleaning of flexible gastrointestinal endoscopes. Endoscopy nurses working in the endoscopy unit at the Princess Alexandra Hospital, Australia, prepared four samples of detergent solution as per normal routine. Twenty-nine nurses participated providing in total 116 samples. There was a significant variation in detergent concentration. The detergent concentration variated between 2.00 and 288.20 ml/L ( M = 34.55, SD = 39.21). Two samples revealed lower concentrations than required. More than 25% of the samples contained at least a 10 times higher concentration than required (>40 ml/L). Current practice of bedside precleaning of gastrointestinal endoscopes was not deemed safe or cost-effective as it did not guarantee an adequate concentration of detergent. More precise methods to establish the required concentration of the bedside precleaning solution were introduced to improve practice.

Abstract
BACKGROUND Effective drying of the internal channels of endoscopes is essential to prevent the growth of water-borne pathogens and to assure adequate sterilization with vaporized hydrogen peroxide or ethylene oxide. The aim of this study was to evaluate the dryness of endoscopes after a routine disinfection process in an automated endoscope reprocessor. METHODS Stripped endoscopes (SE) that allow for visual inspection of the inside channels were reprocessed per protocol in a large urban medical center, with a 3-minute or 10-minute air flush following reprocessing. SE was hung and observed for any water within the channels after reprocessing and after a week of ambient storage. Ready-for-use endoscopes were also randomly spot-checked for moisture visually and with moisture detection paper. RESULTS All SE were grossly wet after HLD with a 3-minute air flush, despite alcohol flush and drying cycle. The 10-minute air flush was effective at drying the biopsy/suction channel, but not the air/water channels. Hanging had limited effect, being most effective in the biopsy/suction channels. Of the 77 ready-for-use respiratory and gastrointestinal endoscopes assessed, 37 (48.1%) showed evidence of retained moisture. CONCLUSIONS Air flush cycles commonly used in the final steps of automated endoscope reprocessing may not adequately dry endoscope channels, particularly the narrower diameter air/water channels. An extended 10-minute air flush appears effective at drying the larger biopsy/suction channel, but has limited effect on the air/water channels.

Abstract
Recently, infection transmission risk associated with contaminated, patient-ready flexible endoscopes has attracted attention. Outbreaks of multidrug-resistant organisms resulting in infection and/or colonization have been particularly concerning. Recent CDC and FDA recommendations focus on reducing "exogenous" infection transmission and specifically recommend that endoscopy sites have quality systems in place for endoscope reprocessing. Another key recommendation is the culture of patient-ready endoscopes to detect contamination with organisms of concern. Remaining gaps in the guidelines include ensuring that optimal endoscope-channel sample methods are used and ensuring effective root-cause analysis and remediation when contamination is detected. In this review, we summarize the critical aspects of endoscope sample collection and present a practical approach to root-cause analysis and remedial action plans.

Abstract
STUDY OBJECTIVE To evaluate the impact of high flow nasal oxygenation (HFNO) on the risk of hypoxemia during gastrointestinal endoscopic procedures (GEPs) under sedation. DESIGN Meta-analysis of randomized controlled trials. SETTING Gastrointestinal endoscopy. INTERVENTION HFNO. PATIENTS Adults patients undergoing GEPs under sedation. MEASUREMENTS The primary outcome was risk of hypoxemia, while the secondary outcomes included risks of severe hypoxemia, hypercapnia, need for jaw thrust or other airway interventions, and procedural interruption as well as procedure time, minimum SpO2, and level of carbon dioxide (CO2). Analyses based on age, gender, flow rate, risk status of patients were performed to investigate subgroup effects. RESULTS Medline, Google scholar, Cochrane Library, and EMBASE databases were searched from inception to July 2021. Seven randomized controlled trials (RCTs) involving 2998 patients published from 2019 to 2021 were included. All GEPs were performed under propofol sedation. Pooled results revealed significantly lower risks of hypoxemia [relative risk (RR) = 0.31, 95% CI:0.13-0.75; 2998 patients], severe hypoxemia (RR = 0.38, 95% CI:0.2-0.74; 2766 patients), other airway interventions (RR = 0.34, 95% CI:0.22-0.52; 2736 patients), procedural interruption (RR = 0.12, 95% CI:0.02-0.64, 451 patients) and a lower CO2 level [standard mean difference (MD) = -0.21, 95% CI: -0.4 to -0.03; 458 patients] in HFNO group compared to control group. Subgroup analysis focusing on risk of hypoxemia showed no significant subgroup effects, indicating consistent benefits of HFNO in different clinical settings. There were no difference in minimum SpO2 (p = 0.06; 262 patients), risk of hypercapnia (p = 0.09; 393 patients), need for jaw thrust (p = 0.28; 2256 patients), and procedure time (p = 0.41, 1004 patients) between the two groups. CONCLUSION Our results demonstrated the efficacy of high flow nasal oxygenation for reducing the risk of hypoxemia in patients receiving elective gastrointestinal endoscopic procedures under sedation. Further studies are warranted to verify its cost-effectiveness in the gastrointestinal endoscopy setting.

Abstract
BACKGROUND At present, the most frequent method for processing flexible gastrointestinal (GI) endoscopes is cleaning followed by high-level disinfection as terminal sterilization is often not practicable. Post-processing monitoring studies consistently show high levels of positive cultures remaining on endoscopes, which can lead to patient infection and even fatality. The processing deficiency is attributed to the complex design of endoscopes, incomplete cleaning, formation of biofilms and lack of margin of safety with high-level disinfection. OBJECTIVE To demonstrate that flexible GI endoscopes can be practicably terminally sterilized. METHODS An endoscope sterilization cycle was developed in a vaporized hydrogen peroxide sterilization system. The cycle was used to study the sterilization of flexible GI endoscopes which included colonoscopes and duodenoscope and material compatibility for both original flexible GI endoscopes and those experimentally modified endoscopes using compatible materials. RESULTS Testing demonstrated that the vaporized hydrogen peroxide can sterilize flexible GI endoscopes (colonoscopes, duodenoscope) with a sterility assurance level of 10-6. Additionally, no recoverable survivors were detected when devices were artificially soiled with hard water and serum. Material compatibility test results demonstrated that replacing molybdenum disulphide lubricant with a graphite-based inert lubricant can make them compatible with vaporized hydrogen peroxide sterilizers. CONCLUSION Flexible GI endoscopes can be practicably terminally sterilized using vaporized hydrogen peroxide sterilization technologies if their materials are revised to become compatible.

Abstract
As part of the activities toward standardizing endoscopy procedures, the Japan Gastroenterological Endoscopy Society has prepared guidelines for cleansing and disinfection of gastrointestinal endoscopes. The environment of gastrointestinal endoscopy differs between Japan and advanced Western countries. In advanced Western countries, gastrointestinal endoscopy is performed almost exclusively at specialized facilities, where strict provisions are observed for cleansing and disinfecting endoscopes. In Japan, however, gastrointestinal endoscopy is performed even in small clinics, and the annual number of gastrointestinal endoscopy cases is enormous. In addition, the method for cleansing and disinfecting endoscopes differs among hospitals. Although there is a distinct lack of evidence for how gastrointestinal endoscopes are cleaned and disinfected, it is necessary to standardize the method for doing so to advance the field of endoscopic medicine.

Abstract
BACKGROUND Endoscopic en bloc resection of larger polyps is relevant because risk of advanced neoplasia or malignancy correlates with tumor size. Recurrence rates after piecemeal endoscopic mucosal resection (EMR) are high and endoscopic submucosal dissection (ESD) is associated with higher complication rates in the western world.
AIM To develop a modified endoscopic en bloc resection technique using an external additional working channel and novel agent for submucosal injection.
METHODS EMR+ was considered as modified grasp and snare technique. For simultaneous use of a grasping and cutting device a novel additional working channel was used (AWC®, Ovesco Endoscopy, Tübingen, Germany). AWC® is installed on the outer surface of the endoscope, covered with a plastic sleeve and designed for single use. For submucosal injection a new agent consisting of poloxamers was used (LiftUp®, Ovesco Endoscopy, Tübingen, Germany). The agent is liquid at room temperature and forms a stable and permanent gel cushion after injection. Safety of LiftUp® has been shown in a pre-clinical study in domestic pigs. LiftUp® is commercially not yet available but approval is expected in early 2019. EMR+ was first developed ex vivo (explanted pig stomach) and subsequently evaluated in vivo (stomach, porcine model, 3 domestic pigs). Main outcome measurements were: Procedure time, macroscopic en bloc resection and adverse events.
RESULTS Concept of EMR+ was first developed ex vivo (explanted pig stomach). Ex vivo, 22 resections were performed after technique was established. Median procedure time (measured from begin of injection to extraction of resection specimen) was 7 min (range 5-11, SD 1.68) and median size of resection specimens was 30 mm × 26 mm × 11 mm ex vivo. Subsequently 13 resections were performed in vivo (stomach, porcine model, 3 domestic pigs). In vivo, median procedure time (measured from begin of injection to extraction of resection specimen) was 5 min (range 3-12, SD 2.72) and median size of resection specimens was 35 mm × 35 mm × 11 mm. In vivo, resection was macroscopic complete in 92.3%, major adverse events were not observed. In one case (7.7%) minor periprocedural bleeding was observed and managed by coagulation.
CONCLUSION EMR+ appeared to be effective and safe and was easy and fast to perform in the porcine model. EMR+ needs to be further evaluated clinically in comparative trials.

Abstract
The advent of video capsule endoscopy into clinical routine more than 15 years ago led to a substantial change in the diagnostic approach to patients with suspected small bowel diseases, often indicating a deep enteroscopy procedure for diagnostical confirmation or endoscopic treatment. Device assisted enteroscopy was developed in 2001 and for the first time established a practicable, safe and effective method for evaluation of the small bowel. Currently with double-balloon enteroscopy, single-balloon enteroscopy and spiral enteroscopy three different platforms are available in clinical routine. Summarizing, double-balloon enteroscopy seems to offer the deepest insertion depth to the small bowel going hand in hand with the disadvantage of a longer procedural duration. Manual spiral enteroscopy seems to be a faster procedure but without reaching the depth of the DBE in currently available data. Finally, single-balloon enteroscopy seems to be the least complicated procedure to perform. Despite substantial improvements in the field of direct enteroscopy, even nowadays deep endoscopic access to the small bowel with all available methods is still a complex procedure, cumbersome and time-consuming and requires high endoscopic skills. This review will give an overview of the currently available techniques and will further discuss the role of the upcoming new technology of the motorized spiral enteroscopy (PowerSpiral).

Abstract
To improve the accuracy and operating flexibility of digestive diagnostic applications in situ, this paper demonstrates the design, fabrication, and evaluation of a miniaturized high-resolution integrated 360° electronic radial ultrasound endoscope. To improve the uniformity between elements of the radial array transducer, an optimal fabrication procedure based on a flexible matching layer was developed. The radial ultrasound endoscope has a 128.3° 5-million-pixel camera module integrated with an approximately 8-MHz 128-element radial ultrasonic array in a package with an outer diameter of 9.5 mm. The results showed that the array has a center frequency of 8.2 MHz, a -6-dB fractional bandwidth of 83.4%, and a two-way insertion loss of 39.62 dB at the center frequency. Annulus and wire phantoms can be distinctly imaged with the radial array. Printed eight-point font can be distinctly imaged with both a large view and a 3-18-mm depth of field in lumen short-range optical imaging. A porcine esophagus can be distinctly imaged in vitro with the integrated endoscope. The results indicate that the fabrication method based on a flexible matching layer can achieve high uniformity between elements of a radial array transducer. In addition, the proposed ultrasound endoscope demonstrates a good image resolution.

Abstract
With the digestive endoscopic tunnel technique (DETT), many diseases that previously would have been treated by surgery are now endoscopically curable by establishing a submucosal tunnel between the mucosa and muscularis propria (MP). Through the tunnel, endoscopic diagnosis or treatment is performed for lesions in the mucosa, in the MP, and even outside the gastrointestinal (GI) tract. At present, the tunnel technique application range covers the following: (1) Treatment of lesions originating from the mucosal layer, e.g., endoscopic submucosal tunnel dissection for oesophageal large or circular early-stage cancer or precancerosis; (2) treatment of lesions from the MP layer, per-oral endoscopic myotomy, submucosal tunnelling endoscopic resection, etc.; and (3) diagnosis and treatment of lesions outside the GI tract, such as resection of lymph nodes and benign tumour excision in the mediastinum or abdominal cavity. With the increasing number of DETTs performed worldwide, endoscopic tunnel therapeutics, which is based on DETT, has been gradually developed and optimized. However, there is not yet an expert consensus on DETT to regulate its indications, contraindications, surgical procedure, and postoperative treatment. The International DETT Alliance signed up this consensus to standardize the procedures of DETT. In this consensus, we describe the definition, mechanism, and significance of DETT, prevention of infection and concepts of DETT-associated complications, methods to establish a submucosal tunnel, and application of DETT for lesions in the mucosa, in the MP and outside the GI tract (indications and contraindications, procedures, pre- and postoperative treatments, effectiveness, complications and treatments, and a comparison between DETT and other operations).

Abstract
An 81-year-old man with esophageal cancer had undergone subtotal thoracic esophagectomy and retrosternal reconstruction using a gastric tube. He developed anemia. Gastrointestinal endoscopy was performed, which revealed a tumor in the posterior wall of the lower part of the gastric tube. Biopsy revealed well-differentiated adenocarcinoma. There was no lymph node metastasis and no distal metastasis on CT. We performed partial resection of the stomach tube because of his age and physical condition. We identified the position of the tumor by upper gastrointestinal series CT and gastrointestinal endoscopy. The tumor was located on the posterior wall of the lower part of the gastric tube and the back of the sternum lower border. Marking was performed by gastrointestinal endoscopy before operation. We simulated the operation and decided to perform laparostomy without sternotomy incision. We cut the anterior wall of the gastric tube in front of the tumor using the endoscope. We could then confirm the diagnosis of cancer, and clipped and removed the tumor from the posterior wall. The resected site was sutured with 4-0 absorbable thread. The pathological diagnosis was T1a(M)N0M0, ly0, v0, PM0, DM0, pStage ⅠA.

Abstract
AIM To evaluate the efficacy of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of pancreatic head cancer when pushing (push method) or pulling the echoendoscope (pull method).
METHODS Overall, 566 pancreatic cancer patients had their first EUS-FNA between February 2001 and December 2017. Among them, 201 who underwent EUS-FNA for pancreatic head lesions were included in this study. EUS-FNA was performed by the push method in 85 patients, the pull method in 101 patients and both the push and pull methods in 15 patients. After propensity score matching (age, sex, tumor diameter, and FNA needle), 85 patients each were stratified into the push and pull groups. Patient characteristics and EUS-FNA-related factors were compared between the two groups.
RESULTS Patient characteristics were not significantly different between the two groups. The distance to lesion was significantly longer in the push group than in the pull group (13.9 ± 4.9 mm vs 7.0 ± 4.9 mm, P < 0.01). The push method was a significant factor influencing the distance to lesion (≥ median 10 mm) (P < 0.01). Additionally, tumor diameter ≥ 25 mm (OR = 1.91, 95%CI: 1.02-3.58, P = 0.043) and the push method (OR = 1.91, 95%CI: 1.03-3.55, P = 0.04) were significant factors contributing to the histological diagnosis of malignancy.
CONCLUSION The pull method shortened the distance between the endoscope and the lesion and facilitated EUS-FNA of pancreatic head cancer. The push method contributed to the histological diagnosis of pancreatic head cancer using EUS-FNA specimens.

Abstract
Aims We describe the fourth reported case of granulomatous gastritis associated with gastric adenocarcinoma, with a review of the literature and considerations about the prognostic implications of this association. Results A 48-year-old woman who had been suffering from gastritis for ten years was admitted to our institute for increasing left epigastric pain associated with vomiting. After an endoscopic biopsy had revealed an ulcerated signet ring cell carcinoma, the patient was submitted to subtotal gastrectomy with regional lymph node dissection. Pathological examination of the resected specimen revealed a superficial signet ring cell carcinoma (early cancer) associated with multiple granulomas. The granulomas, which were observed within the mucosa and the submucosa at the periphery of the carcinoma, were composed of CD68-positive, CD15-negative epithelioid and giant cells of the Langhans type, confirming their true histiocytic nature, and were also extensively found within the dissected lymph nodes. Since no ocular, skin, pulmonary or other gastrointestinal lesions were found and the granulomas were negative for acid-fast and fungal stain, a diagnosis of granulomatous gastritis was made. Conclusions To the best of our knowledge this is the fourth example of gastric adenocarcinoma and granulomatous gastritis. These cases suggest an association between granulomatous gastritis and early gastric cancer.

Abstract
A 66-year-old man presented with recurrences in the peritoneum 3 years after heavy particle beam therapy with hepatocellular carcinoma(HCC)and underwent laparoscopic surgery.Five months after surgery, a new peritoneal dissemination found in the vicinity of the colon hepatic flexure area by CT examination, and laparoscopic resection was planned again.Indocyanine green(ICG)0.5 mg/kg was administered on the day before surgery.ICG imaging by the PINPOINT®system revealed 2 small ICG accumulation sites in the diaphragm, as well as the main lesion, and each lesion was excised laparoscopically.All lesions were diagnosed as peritoneal dissemination of HCC, and the postoperative course was uneventful.Although new dissemination nodules were appeared 6 months after surgery, he underwent laparoscopic surgery again and survives.In PINPOINT fluorescence mode, high-definition white-light image and fluorescence image was combined, and it was easy to determine the cut line but also to visualize the small lesion difficult to identify in the visible light mode.It was suggested that the PINPOINT®system might be useful in cases of HCC peritoneal dissemination.

Abstract
OBJECTIVE this work presents the design, fabrication, and testing of a miniaturized and integrated ultrasound endoscope for use as an in situ digestive diagnostic device to facilitate real-time ultrasound guidance of intervention treatments. METHODS we designed an optimal structure to integrate an auto-focus 5-megapixel camera module with an 8-MHz, 64-element curvilinear ultrasonic array in one miniaturized package. A novel three-axis auto-focusing voice coil motor (VCM) was designed and manufactured for the camera module to move the lens position for auto-focusing and to adjust the lens tilt. RESULTS the results showed that the array had a center frequency of 8.09 MHz and a -6-dB fractional bandwidth of 83%. At the center frequency, the two-way insertion loss was 40.6 dB. Endoscopic ultrasound imaging demonstrated satisfactory performance for imaging an anthropomorphic phantom of the esophagus. By slightly adjusting the tilt angle of the optical axis of the lens, the optical image captured by the auto-focusing lens obtained improved definition regardless of changes in the view angle of the camera with respect to the objects being captured. CONCLUSION the integrated convex ultrasound endoscope, possessing minimal size, improved optical imaging definition, and good ultrasound imaging performance, can become a useful tool in digestive tract imaging. SIGNIFICANCE the miniaturized and integrated convex ultrasound endoscope can facilitate real-time ultrasound intervention guidance, reducing risks associated with the operation.

Abstract
AIM To determine the frequency of bleeding source detection in patients with obscure gastrointestinal bleeding (OGIB) who underwent double balloon enteroscopy (DBE) after pre-procedure imaging [multiphase computed tomography enterography (MPCTE), video capsule endoscopy (VCE), or both] and assess the impact of imaging on DBE diagnostic yield.
METHODS Retrospective cohort study using a prospectively maintained database of all adult patients presenting with OGIB who underwent DBE from September 1st, 2002 to June 30th, 2013 at a single tertiary center.
RESULTS Four hundred and ninety five patients (52% females; median age 68 years) underwent DBE for OGIB. AVCE and/or MPCTE performed within 1 year prior to DBE (in 441 patients) increased the diagnostic yield of DBE (67.1% with preceding imaging vs 59.5% without). Using DBE as the gold standard, VCE and MPCTE had a diagnostic yield of 72.7% and 32.5% respectively. There were no increased odds of finding a bleeding site at DBE compared to VCE (OR = 1.3, P = 0.150). There were increased odds of finding a bleeding site at DBE compared to MPCTE (OR = 5.9, P < 0.001). In inpatients with overt OGIB, diagnostic yield of DBE was not affected by preceding imaging.
CONCLUSION DBE is a safe and well-tolerated procedure for the diagnosis and treatment of OGIB, with a diagnostic yield that may be increased after obtaining a preceding VCE or MPCTE. However, inpatients with active ongoing bleeding may benefit from proceeding directly to antegrade DBE.

Abstract
AIM To evaluate rebleeding, primary failure (PF) and mortality of patients in whom over-the-scope clips (OTSCs) were used as first-line and second-line endoscopic treatment (FLET, SLET) of upper and lower gastrointestinal bleeding (UGIB, LGIB).
METHODS A retrospective analysis of a prospectively collected database identified all patients with UGIB and LGIB in a tertiary endoscopic referral center of the University of Freiburg, Germany, from 04-2012 to 05-2016 (n = 93) who underwent FLET and SLET with OTSCs. The complete Rockall risk scores were calculated from patients with UGIB. The scores were categorized as < or ≥ 7 and were compared with the original Rockall data. Differences between FLET and SLET were calculated. Univariate and multivariate analysis were performed to evaluate the factors that influenced rebleeding after OTSC placement.
RESULTS Primary hemostasis and clinical success of bleeding lesions (without rebleeding) was achieved in 88/100 (88%) and 78/100 (78%), respectively. PF was significantly lower when OTSCs were applied as FLET compared to SLET (4.9% vs 23%, P = 0.008). In multivariate analysis, patients who had OTSC placement as SLET had a significantly higher rebleeding risk compared to those who had FLET (OR 5.3; P = 0.008). Patients with Rockall risk scores ≥ 7 had a significantly higher in-hospital mortality compared to those with scores < 7 (35% vs 10%, P = 0.034). No significant differences were observed in patients with scores < or ≥ 7 in rebleeding and rebleeding-associated mortality.
CONCLUSION Our data show for the first time that FLET with OTSC might be the best predictor to successfully prevent rebleeding of gastrointestinal bleeding compared to SLET. The type of treatment determines the success of primary hemostasis or primary failure.

Abstract
We report a successful tracheal intubation in a low birth weight infant with difficult airway by using an upper gastrointestinal endoscope. A 1-day-old female weighing 1.8 kg having micrognathia, lateral facial cleft, and bilateral microtia suggestive of Goldenhar syn- drome complicated with total anomalous pulmonary venous connection was scheduled for surgical repair of duodenal atresia. Awake intubation was planned because of anticipated difficult intubation. Direct laryn- goscopy with Miller blade (size 0) after intravenous lidocaine did not visualize the larynx or epiglottis (Cor- mack-Lehane grade 4). After several failed attempts at intubation using BURP procedure, Pentax Airway Scope? equipped with a neonatal-type Intlock* (ITL- N) was tried but a good view of the larynx was not obtained because of the narrow oral cavity and copious secretion. After failed attempts with Airway Scope?, an upper gastrointestinal endoscope was inserted into the oral cavity and equipped insufflation and suctioning of the secretion were utilized, which provided a good view of the vocal cords and enabled nasotracheal intu- bation. An upper gastrointestinal endoscope could provide a good view of the larynx by using insufflation, and suc- tioning, and can be one of the useful devices for tra- cheal intubation of difficult airway.

Abstract
A 71-year-old man was referred to our hospital and was diagnosed with jaundice and a liver function disorder. Although we suspected an intraductal papillary neoplasm of the bile duct (IPNB)-derived caudate branches on the basis of contrast-enhanced CT, MRI, and endoscopic retrograde cholangiopancreatography, we could not clearly identify the tumor. Therefore, we examined the lesion using endoscopic ultrasonography (EUS). We could visualize an iso-hyperechoic elevated tumor in the caudate branches. The tumor was observed as a hypervascular lesion using contrast-enhanced EUS, which is useful in preoperatively diagnosing IPNB and detecting the presence of lesions.

Abstract
Advances in endoluminal instrumentation and technology are enabling endoscopists to perform increasingly sophisticated procedures. Indications for these procedures are likely to expand as outcomes studies show they are efficacious and cost-effective. This article highlights several recent advances in endoluminal suturing, dissecting, and ligating and discusses the impact of these advances on the practice of gastrointestinal surgery. Endoluminal suturing offers select patients with gastroesophageal reflux disease a safe and effective alternative to laparoscopic surgery. Devices designed for endoluminal hemostasis and endoscopic mucosal resection can be used effectively for a broader range of applications and are already being used to perform transluminal surgery in animal models; human trials are forthcoming. Gastrointestinal surgeons should support efforts to critically evaluate endoluminal techniques because they have an opportunity to improve care. Surgical residents planning careers in gastrointestinal surgery need to understand endoscopic techniques and consider their training opportunities.

Abstract
Conventional endoscopic resection techniques such as endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) are powerful tools for the treatment of gastrointestinal (GI) neoplasms. However, those techniques are limited to the superficial layers of the GI wall (mucosa and submucosa). Lesions without lifting sign (usually arising from deeper layers) or lesions in difficult anatomic positions (appendix, diverticulum) are difficult - if not impossible - to resect using conventional techniques, due to the increased risk of complications. For larger lesions (>2 cm), ESD appears to be superior to the conventional techniques because of the en bloc resection, but the procedure is technically challenging, time consuming, and associated with complications even in experienced hands. Since the development of the over-the-scope clips (OTSC), complications like bleeding or perforation can be endoscopically better managed. In recent years, different endoscopic full-thickness resection techniques came to the focus of interventional endoscopy. Since September 2014, the full-thickness resection device (FTRD) has the CE marking in Europe for full-thickness resection in the lower GI tract. Technically the device is based on the OTSC system and combines OTSC application and snare polypectomy in one step. This study shows all full-thickness resection techniques currently available, but clearly focuses on the experience with the FTRD in the lower GI tract.

Abstract
Multiple robotic flexible endoscope platforms have been developed based on cross specialty collaboration between engineers and medical doctors. However, significant number of these platforms have been developed for the natural orifice transluminal endoscopic surgery paradigm. Increasing amount of evidence suggest the focus of development should be placed on advanced endolumenal procedures such as endoscopic submucosal dissection instead. A thorough literature analysis was performed to assess the current status of robotic flexible endoscopic platforms designed for advanced endolumenal procedures. Current efforts are mainly focused on robotic locomotion and robotic instrument control. In the future, advances in actuation and servoing technology, optical analysis, augmented reality and wireless power transmission technology will no doubt further advance the field of robotic endoscopy. Globally, health systems have become increasingly budget conscious; widespread acceptance of robotic endoscopy will depend on careful design to ensure its delivery of a cost effective service.

Abstract
AIM: To investigate the efficacy and clinical outcome of patients treated with an over-the-scope-clip (OTSC) system for severe gastrointestinal hemorrhage, perforations and fistulas.
METHODS: From 02-2009 to 10-2012, 84 patients were treated with 101 OTSC clips. 41 patients (48.8%) presented with severe upper-gastrointestinal (GI) bleeding, 3 (3.6%) patients with lower-GI bleeding, 7 patients (8.3%) underwent perforation closure, 18 patients (21.4%) had prevention of secondary perforation, 12 patients (14.3%) had control of secondary bleeding after endoscopic mucosal resection or endoscopic submucosal dissection (ESD) and 3 patients (3.6%) had an intervention on a chronic fistula.
RESULTS: In 78/84 patients (92.8%), primary treatment with the OTSC was technically successful. Clinical primary success was achieved in 75/84 patients (89.28%). The overall mortality in the study patients was 11/84 (13.1%) and was seen in patients with life threatning upper GI hemorrhage. There was no mortality in any other treatment group. In detail OTSC application lead to a clinical success in 35/41 (85.36%) patients with upper GI bleeding and in 3/3 patients with lower GI bleeding. Technical success of perforation closure was 100% while clinical success was seen in 4/7 cases (57.14%) due to attendant circumstances unrelated to the OTSC. Technical and clinic success was achieved in 18/18 (100%) patients for the prevention of bleeding or perforation after endoscopic mucosal resection and ESD and in 3/3 cases of fistula closure. Two application-related complications were seen (2%).
CONCLUSION: This largest single center experience published so far confirms the value of the OTSC for GI emergencies and complications. Further clinical experience will help to identify optimal indications for its targeted and prophylactic use.

Abstract
Background The intestinal microbiota is increasingly linked to the pathogenesis of chronic enteropathies (CE) in dogs. While imbalances in duodenal and fecal microbial communities have been associated with mucosal inflammation, relatively little is known about alterations in mucosal bacteria seen with CE involving the ileum and colon. Aim To investigate the composition and spatial organization of mucosal microbiota in dogs with CE and controls. Methods Tissue sections from endoscopic biopsies of the ileum and colon from 19 dogs with inflammatory bowel disease (IBD), 6 dogs with granulomatous colitis (GC), 12 dogs with intestinal neoplasia, and 15 controls were studied by fluorescence in situ hybridization (FISH) on a quantifiable basis. Results The ileal and colonic mucosa of healthy dogs and dogs with CE is predominantly colonized by bacteria localized to free and adherent mucus compartments. CE dogs harbored more (P < 0.05) mucosal bacteria belonging to the Clostridium-coccoides/Eubacterium rectale group, Bacteroides, Enterobacteriaceae, and Escherichia coli versus controls. Within the CE group, IBD dogs had increased (P < 0.05) Enterobacteriaceae and E. coli bacteria attached onto surface epithelia or invading within the intestinal mucosa. Bacterial invasion with E. coli was observed in the ileal and colonic mucosa of dogs with GC (P < 0.05). Dogs with intestinal neoplasia had increased (P < 0.05) adherent (total bacteria, Enterobacteriaceae, E. coli) and invasive (Enterobacteriaceae, E. coli, and Bacteroides) bacteria in biopsy specimens. Increased numbers of total bacteria adherent to the colonic mucosa were associated with clinical disease severity in IBD dogs (P < 0.05). Conclusion Pathogenic events in canine CE are associated with different populations of the ileal and colonic mucosal microbiota.

Abstract
Noninvasive imaging with CT and magnetic resonance enterography or direct visualization with wireless capsule endoscopy can provide valuable diagnostic information and direct therapy. Enteroscopy technology and techniques have evolved significantly and allow diagnosis and therapy deep within the small bowel, previously attainable only with intraoperative enteroscopy. Push enteroscopy, readily available in most endoscopy units, plays an important role in the evaluation and management of lesions located up to the proximal jejunum. Currently available device-assisted enteroscopy systems, DBE, SBE, and spiral enteroscopy each have their technical nuances, clinical advantages, and limitations. Newer, on-demand enteroscopy systems appear promising, but further studies are needed. Despite slight differences in parameters such as procedural times, depths of insertion, and rates of complete enteroscopy, the overall clinical outcomes with all overtube-assisted systems appear to be similar. Endoscopists should therefore master the enteroscopy technology based on institutional availability and their level of technical expertise.

Abstract
BACKGROUND AND AIMS Reports on the performance of unsedated ultrathin endoscopy via the transnasal (uTNE) and transoral (uTOE) routes are conflicting. We aimed to estimate the technical success rate, patient preference, and acceptability of uTNE and uTOE alone and in comparison with conventional EGD (cEGD; with or without sedation). METHODS A systematic review and meta-analysis was performed on all primary studies reporting the outcomes of interest. Electronic databases (Cochrane library, MEDLINE, EMBASE) were searched on February 1, 2014. RESULTS Thirty-four studies met the inclusion criteria with 6659 patients in total. The pooled technical success rate was 94.0% for uTNE (95% confidence interval [CI], 91.6-95.8; 30 studies) and 97.8% for uTOE (95% CI, 95.6-98.9; 16 studies). The difference in proportion of success for uTNE compared with cEGD was -2.0% (95% CI, -4.0 to -1.0; 18 studies), but that difference was not significant when uTNE < 5.9 mm in diameter was used (-1.0%; 95% CI, -3.0 to .0; 9 studies). There was no significant difference in success rate between uTOE and cEGD (.0%; 95% CI, -1.0 to 2.0; 10 studies). The pooled difference in proportion of patients who preferred uTNE over cEGD was 63.0% (95% CI, 49.0-76.0; 10 studies), whereas preference for uTOE versus cEGD was not significantly different (38.0%; 95% CI, -4.0 to 80.0; 2 studies). Acceptability was high for both uTNE (85.2%; 95% CI, 79.1-89.9; 16 studies) and uTOE (88.7%; 95% CI, 82.4-92.9; 10 studies). CONCLUSIONS Technical success rate for uTNE < 5.9 mm is equivalent to cEGD. uTNE has high patient acceptability, with better patient preference, and therefore could be a useful alternative to cEGD for screening purposes. uTOE had a similar technical success rate but an equivocal preference to cEGD.

Abstract
Conventional endoscopic resection techniques such as endoscopic mucosal resection or endoscopic submucosal dissection are powerful tools for treatment of gastrointestinal neoplasms. However, those techniques are restricted to superficial layers of the gastrointestinal wall. Endoscopic full-thickness resection (EFTR) is an evolving technique, which is just about to enter clinical routine. It is not only a powerful tool for diagnostic tissue acquisition but also has the potential to spare surgical therapy in selected patients. This review will give an overview about current EFTR techniques and devices.

Abstract
AIM: To compare the outcomes of endoscopic mucosal resection with a cap (EMR-C) with those of endoscopic submucosal dissection (ESD) for the resection of rectal neuroendocrine tumors.
METHODS: One hundred and sixteen lesions in 114 patients with rectal neuroendocrine tumor (NET) resected with EMR-C or ESD were included in the study. This study was performed at Pusan National University Yangsan Hospital between July 2009 and August 2014. We analyzed endoscopic complete resection rate, pathologic complete resection rate, procedure time, and adverse events in the EMR-C (n = 65) and ESD (n = 51) groups. We also performed a subgroup analysis by tumor size.
RESULTS: Mean tumor size was 4.62 ± 1.66 mm in the EMR-C group and 7.73 ± 3.14 mm in the ESD group (P < 0.001). Endoscopic complete resection rate was 100% in both groups. Histologic complete resection rate was significantly greater in the EMR-C group (92.3%) than in the ESD group (78.4%) (P = 0.042). Mean procedure time was significantly longer in the ESD group (14.43 ± 7.26 min) than in the EMR-C group (3.83 ± 1.17 min) (P < 0.001). Rates of histologic complete resection without complication were similar for tumor diameter ≤ 5 mm (EMR-C, 96%; ESD, 100%, P = 0.472) as well as in cases of 5 mm < tumor diameter ≤ 10 mm (EMR-C, 80%; ESD, 71.0%, P = 0.524).
CONCLUSION: EMR-C may be simple, faster, and more effective than ESD in removing rectal NETs and may be preferable for resection of small rectal NETs.

Abstract
Transanal endoscopic surgery (TES) consists of a series of anorectal surgical procedures using different devices that are introduced into the anal canal. TES has been developed significantly since it was first used in the 1980s. The key point for the success of these techniques is how accurately patients are selected. The main indication was the resection of endoscopically unresectable adenomas. In recent years, these techniques have become more widespread which has allowed them to be applied in conservative rectal procedures for both benign diseases and selected cases of rectal cancer. For more advanced rectal cancers it should be considered palliative or, in some controlled trials, experimental. The role of newer endoscopic techniques available has not yet been defined. TES may allow for new strategies in the treatment of rectal pathology, like transanal natural orifice transluminal endoscopic surgery or total mesorectal excision.
