Bowel preparation for colonoscopy: European Society of Gastrointestinal Endoscopy (ESGE) guideline.

BACKGROUND AND AIM: This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). It addresses the choice amongst regimens available for cleansing the colon in preparation for colonoscopy. METHODS: This Guideline is based on a targeted literature search to evaluate the evidence supporting the use of bowel preparation for colonoscopy. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was adopted to define the strength of recommendation and the quality of evidence. RESULTS: The main recommendations are as follows. (1) The ESGE recommends a low-fiber diet on the day preceding colonoscopy (weak recommendation, moderate quality evidence). (2) The ESGE recommends a split regimen of 4 L of polyethylene glycol (PEG) solution (or a same-day regimen in the case of afternoon colonoscopy) for routine bowel preparation. A split regimen (or same-day regimen in the case of afternoon colonoscopy) of 2 L PEG plus ascorbate or of sodium picosulphate plus magnesium citrate may be valid alternatives, in particular for elective outpatient colonoscopy (strong recommendation, high quality evidence). In patients with renal failure, PEG is the only recommended bowel preparation. The delay between the last dose of bowel preparation and colonoscopy should be minimized and no longer than 4 hours (strong recommendation, moderate quality evidence). (3) The ESGE advises against the routine use of sodium phosphate for bowel preparation because of safety concerns (strong recommendation, low quality evidence).

European Society of Gastrointestinal Endoscopy (ESGE) Guideline Development Policy.

Numerous scientific publications explore the field of gastrointestinal (GI) endoscopy (a Pubmed search currently yields > 73000 results). Therefore, guidelines have become an indispensable tool for incorporating up-to-date knowledge into daily clinical care. Since the 1990 s, the issuing of guidelines has been a central task of the European Society of Gastrointestinal Endoscopy (ESGE). Here, the ESGE clarifies the types of policy documents that it issues and the methodology used to produce them, taking into account recent methodological developments.

Biliary stenting: indications, choice of stents and results: European Society of Gastrointestinal Endoscopy (ESGE) clinical guideline.

This article is part of a combined publication that expresses the current view of the European Society of Gastrointestinal Endoscopy about endoscopic biliary stenting. The present Clinical Guideline describes short-term and long-term results of biliary stenting depending on indications and stent models; it makes recommendations on when, how, and with which stent to perform biliary drainage in most common clinical settings, including in patients with a potentially resectable malignant biliary obstruction and in those who require palliative drainage of common bile duct or hilar strictures. Treatment of benign conditions (strictures related to chronic pancreatitis, liver transplantation, or cholecystectomy, and leaks and failed biliary stone extraction) and management of complications (including stent revision) are also discussed. A two-page executive summary of evidence statements and recommendations is provided. A separate Technology Review describes the models of biliary stents available and the stenting techniques, including advanced techniques such as insertion of multiple plastic stents, drainage of hilar strictures, retrieval of migrated stents and combined stenting in malignant biliary and duodenal obstructions.The target readership for the Clinical Guideline mostly includes digestive endoscopists, gastroenterologists, oncologists, radiologists, internists, and surgeons while the Technology Review should be most useful to endoscopists who perform biliary drainage.

Learning, techniques, and complications of endoscopic ultrasound (EUS)-guided sampling in gastroenterology: European Society of Gastrointestinal Endoscopy (ESGE) Technical Guideline.

This article is the second of a two-part publication that expresses the current view of the European Society of Gastrointestinal Endoscopy (ESGE) about endoscopic ultrasound (EUS)-guided sampling, including EUS-guided fine needle aspiration (EUS-FNA) and EUS-guided Trucut biopsy. The first part (the Clinical Guideline) focused on the results obtained with EUS-guided sampling, and the role of this technique in patient management, and made recommendations on circumstances that warrant its use. The current Technical Guideline discusses issues related to learning, techniques, and complications of EUS-guided sampling, and to processing of specimens. Technical issues related to maximizing the diagnostic yield (e.g., rapid on-site cytopathological evaluation, needle diameter, microcore isolation for histopathological examination, and adequate number of needle passes) are discussed and recommendations are made for various settings, including solid and cystic pancreatic lesions, submucosal tumors, and lymph nodes. The target readership for the Clinical Guideline mostly includes gastroenterologists, oncologists, internists, and surgeons while the Technical Guideline should be most useful to endoscopists who perform EUS-guided sampling. A two-page executive summary of evidence statements and recommendations is provided.

Radiation protection in digestive endoscopy: European Society of Digestive Endoscopy (ESGE) guideline.

This article expresses the current view of the European Society of Gastrointestinal Endoscopy (ESGE) about radiation protection for endoscopic procedures, in particular endoscopic retrograde cholangiopancreatography (ERCP). Particular cases, including pregnant women and pediatric patients, are also discussed. This Guideline was developed by a group of endoscopists and medical physicists to ensure that all aspects of radiation protection are adequately dealt with. A two-page executive summary of evidence statements and recommendations is provided. The target readership for this Guideline mostly includes endoscopists, anesthesiologists, and endoscopy assistants who may be exposed to X-rays during endoscopic procedures.

Endoscopic treatment of chronic pancreatitis: European Society of Gastrointestinal Endoscopy (ESGE) Clinical Guideline.

BACKGROUND AND AIMS: Clarification of the position of the European Society of Gastrointestinal Endoscopy (ESGE) regarding the interventional options available for treating patients with chronic pancreatitis. METHODS: Systematic literature search to answer explicit key questions with levels of evidence serving to determine recommendation grades. The ESGE funded development of the Guideline. SUMMARY OF SELECTED RECOMMENDATIONS: For treating painful uncomplicated chronic pancreatitis, the ESGE recommends extracorporeal shockwave lithotripsy/endoscopic retrograde cholangiopancreatography as the first-line interventional option. The clinical response should be evaluated at 6 - 8 weeks; if it appears unsatisfactory, the patient's case should be discussed again in a multidisciplinary team. Surgical options should be considered, in particular in patients with a predicted poor outcome following endoscopic therapy (Recommendation grade B). For treating chronic pancreatitis associated with radiopaque stones ≥ 5 mm that obstruct the main pancreatic duct, the ESGE recommends extracorporeal shockwave lithotripsy as a first step, combined or not with endoscopic extraction of stone fragments depending on the expertise of the center (Recommendation grade B). For treating chronic pancreatitis associated with a dominant stricture of the main pancreatic duct, the ESGE recommends inserting a single 10-Fr plastic stent, with stent exchange planned within 1 year (Recommendation grade C). In patients with ductal strictures persisting after 12 months of single plastic stenting, the ESGE recommends that available options (e. g., endoscopic placement of multiple pancreatic stents, surgery) be discussed in a multidisciplinary team (Recommendation grade D).For treating uncomplicated chronic pancreatic pseudocysts that are within endoscopic reach, the ESGE recommends endoscopic drainage as a first-line therapy (Recommendation grade A).For treating chronic pancreatitis-related biliary strictures, the choice between endoscopic and surgical therapy should rely on local expertise, patient co-morbidities and expected patient compliance with repeat endoscopic procedures (Recommendation grade D). If endoscopy is elected, the ESGE recommends temporary placement of multiple, side-by-side, plastic biliary stents (Recommendation grade A).

Management of precancerous conditions and lesions in the stomach (MAPS): guideline from the European Society of Gastrointestinal Endoscopy (ESGE), European Helicobacter Study Group (EHSG), European Society of Pathology (ESP), and the Sociedade Portuguesa de Endoscopia Digestiva (SPED).

Atrophic gastritis, intestinal metaplasia, and epithelial dysplasia of the stomach are common and are associated with an increased risk for gastric cancer. In the absence of guidelines, there is wide disparity in the management of patients with these premalignant conditions. The European Society of Gastrointestinal Endoscopy (ESGE), the European Helicobacter Study Group (EHSG), the European Society of Pathology (ESP) and the Sociedade Portuguesa de Endoscopia Digestiva (SPED) have therefore combined efforts to develop evidence-based guidelines on the management of patients with precancerous conditions and lesions of the stomach (termed MAPS). A multidisciplinary group of 63 experts from 24 countries developed these recommendations by means of repeat online voting and a meeting in June 2011 in Porto, Portugal. The recommendations emphasize the increased cancer risk in patients with gastric atrophy and metaplasia, and the need for adequate staging in the case of high grade dysplasia, and they focus on treatment and surveillance indications and methods.

Colon capsule endoscopy: European Society of Gastrointestinal Endoscopy (ESGE) Guideline.

PillCam colon capsule endoscopy (CCE) is an innovative noninvasive, and painless ingestible capsule technique that allows exploration of the colon without the need for sedation and gas insufflation. Although it is already available in European and other countries, the clinical indications for CCE as well as the reporting and work-up of detected findings have not yet been standardized. The aim of this evidence-based and consensus-based guideline, commissioned by the European Society of Gastrointestinal Endoscopy (ESGE) is to furnish healthcare providers with a comprehensive framework for potential implementation of this technique in a clinical setting.

Biliary stents: models and methods for endoscopic stenting.

Biliary stenting is widely used to palliate malignant obstruction or to treat benign biliary diseases. Recently, the most important changes have related to self-expandable metal stents (SEMSs), which are now available in a wide variety of designs, and to treatment techniques. This article is part of a combined publication that expresses the current view of the European Society of Gastrointestinal Endoscopy (ESGE) about endoscopic biliary stenting: a technology review describes the stent models and stenting techniques, and a separate clinical guideline states the evidence and recommendations regarding stenting.

Indications, results, and clinical impact of endoscopic ultrasound (EUS)-guided sampling in gastroenterology: European Society of Gastrointestinal Endoscopy (ESGE) Clinical Guideline.

This article is part of a combined publication that expresses the current view of the European Society of Gastrointestinal Endoscopy (ESGE) about endoscopic ultrasound (EUS)-guided sampling in gastroenterology, including EUS-guided fine needle aspiration (EUS-FNA) and EUS-guided trucut biopsy (EUS-TCB), of submucosal tumors, diffuse esophageal/gastric wall thickening, pancreatic solid masses and cystic-appearing lesions, mediastinal lesions unrelated to lung or esophageal cancer, cancer of the esophagus, stomach, and rectum, lymph nodes of unknown origin, adrenal gland masses, and focal liver lesions. False-positive cytopathological results and needle tract seeding are also discussed. The present Clinical Guideline describes the results of EUS-guided sampling in the different clinical settings, considers the role of this technique in patient management, and makes recommendations on circumstances that warrant its use. A two-page executive summary of evidence statements and recommendations is provided. A separate Technical Guideline describes the general technique of EUS-guided sampling, particular techniques to maximize the diagnostic yield depending on the nature of the target lesion, and sample processing. The target readership for the Clinical Guideline mostly includes gastroenterologists, oncologists, internists, and surgeons while the Technical Guideline should be most useful to endoscopists who perform EUS-guided sampling.

Endoscopy and antiplatelet agents. European Society of Gastrointestinal Endoscopy (ESGE) Guideline.

With the increasing use of antiplatelet agents (APA), their management during the periendoscopic period has become a more common and more difficult problem. The increase in use is due to the availability of new drugs and the widespread use of drug-eluting coronary stents. Acute coronary syndromes can occur when APA therapy is withheld for noncardiovascular interventions. Guidelines about APA management during the periendoscopic period are traditionally based on assessments of the procedure-related risk of bleeding and the risk of thrombosis if APA are stopped. New data allow better assessment of these risks, of the necessary duration of APA discontinuation before endoscopy, of the use of alternative procedures (mostly for endoscopic retrograde cholangiopancreatography [ERCP]), and of endoscopic methods that can be used to prevent bleeding (following colonic polypectomy). This guideline makes graded, evidence-based, recommendations for the management of APA for all currently performed endoscopic procedures. A short summary and two tables are included for quick reference.

European Society of Gastrointestinal Endoscopy (ESGE) guideline: the use of electrosurgical units.

Electrosurgery is used in the majority of endoscopic therapeutic procedures. An understanding of the fundamental electrosurgical principles and various settings available on electrosurgical units is essential for the safe and effective use of electrosurgery during endoscopy. The aims of these technical guidelines are to: (1) expose physical principles relevant to the understanding of electrosurgery during endoscopy; (2) describe and provide practical recommendations regarding electrosurgical units that are commonly in use; (3) discuss the clinical relevance of technologies recently implemented in newer electrosurgical units; and (4) review factors relevant to commonly performed therapeutic procedures, including polypectomy, sphincterotomy, contact thermal hemostasis, and argon plasma coagulation.

European Society of Gastrointestinal Endoscopy (ESGE) Guideline: prophylaxis of post-ERCP pancreatitis.

Pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Risk factors for post-ERCP pancreatitis (PEP) are both patient-related and procedure-related. Identification of patients at high risk for PEP is important in order to target prophylactic measures. Prevention of PEP includes administration of nonsteroidal inflammatory drugs (NSAIDs), use of specific cannulation techniques, and placement of temporary pancreatic stents. The aim of this guideline commissioned by the European Society of Gastrointestinal Endoscopy (ESGE) is to provide practical, graded, recommendations for the prevention of PEP.

European Society of Gastrointestinal Endoscopy, European Society of Gastroenterology and Endoscopy Nurses and Associates, and the European Society of Anaesthesiology Guideline: Non-anesthesiologist administration of propofol for GI endoscopy.

Propofol sedation by non-anesthesiologists is an upcoming sedation regimen in several countries throughout Europe. Numerous studies have shown the efficacy and safety of this sedation regimen in gastrointestinal endoscopy. Nevertheless, this issue remains highly controversial. The aim of this evidence- and consensus-based set of guideline is to provide non-anesthesiologists with a comprehensive framework for propofol sedation during digestive endoscopy. This guideline results from a collaborative effort from representatives of the European Society of Gastrointestinal Endoscopy (ESGE), the European Society of Gastroenterology and Endoscopy Nurses and Associates (ESGENA) and the European Society of Anaesthesiology (ESA). These three societies have endorsed the present guideline.

What gastroenterologists should know about direct oral anticoagulants.

Direct oral anticoagulants are being increasingly used in patients with non-valvular atrial fibrillation and venous thromboembolism, due to their improved efficacy/ safety ratio, a predictable anticoagulant effect without need for routine coagulation monitoring, and fewer food and drug interactions compared with vitamin K antagonists. Gastrointestinal bleeding remains a serious complication, whose management is challenging for gastroenterologists due to the lack of a standardized clinical approach. Clinical experience on periendoscopic management of these drugs is still limited and there is a paucity of clinical data supporting guidelines recommendations', and this ultimately turns out in different, unsubstantiated and potentially harmful practices of patient management. Present study will provide a thorough revision on the risk of GI bleeding for DOAC therapy and the identification of patient risk factors to individualize treatment. Moreover, the approach to management of DOACs in case of bleeding complications is discussed, and an algorithm of different strategies in presence or not of plasma level measurement is proposed. Finally the periendoscopic management for elective procedures will be reviewed, at the light of the guideline recommendations and new evidences from observational studies.

Partially covered self-expandable metallic stents for benign biliary strictures due to chronic pancreatitis.

BACKGROUND AND STUDY AIMS: Benign biliary strictures (BBS) may occur in patients with chronic pancreatitis and may lead to secondary biliary cirrhosis or recurrent cholangitis. Although surgical diversion may provide definitive therapy, it can be associated with significant morbidity. Endoscopic therapy with plastic stents has been used as an alternative to surgery but has resulted in unsatisfactory long-term outcomes. We evaluated the temporary placement of partially covered self-expandable metallic stents (PCMS) in patients with BBS due to chronic pancreatitis. PATIENTS AND METHODS: A total of 20 patients with BBS due to chronic pancreatitis underwent temporary placement of PCMS over a 6-year period. The primary outcome of interest was the proportion of patients with stricture resolution persisting 6 months after stent removal. Secondary outcomes included the stent failure rate, number of endoscopic sessions required to achieve biliary drainage, total duration of stenting, and complication rate. RESULTS: Adequate biliary drainage was achieved in 19 patients with PCMS (95%). Eighteen of the 20 patients (90%) had persistent stricture resolution 6 months after PCMS removal. In two of the 20 patients (10%), PCMS stenting failed and these patients underwent alternative therapies. Complications occurred in four patients (20%). Median duration of PCMS placement was 5 months, requiring a median of two endoscopic procedures. CONCLUSION: In this series of patients with BBS due to chronic pancreatitis, temporary PCMS placement achieved persistent stricture resolution in the majority of patients with acceptable complication rates. Comparative trials evaluating temporary PCMS placement and plastic stenting in patients with BBS due to chronic pancreatitis are needed.

Intragastric balloon for weight loss: results in 100 individuals followed for at least 2.5 years.

BACKGROUND AND STUDY AIMS: To determine long-term outcome after treatment with an intragastric balloon for 6 months, with no structured weight maintenance program offered after balloon removal. PATIENTS AND METHODS: 100 consecutive overweight/obese individuals (mean body mass index [BMI] 35.0 +/- 5.6 kg/m (2)) were prospectively followed after endoscopic implantation of a saline-filled intragastric balloon; 97 completed final follow-up at a mean of 4.8 +/- 1.6 years. Successful intragastric balloon therapy was defined as weight loss at 6 months of > or = 10 % of weight at baseline, that remained > or = 10 % until 2.5 years, without bariatric surgery. All analyses followed intention-to-treat principles. RESULTS: At 6 months, mean weight loss was 12.6 +/- 8.3 kg, 63 individuals had > or = 10 % baseline weight loss; no severe morbidity was detected. During the first and second years following intragastric balloon removal, mean body mass increased by 4.2 +/- 6.8 and 2.3 +/- 6.0 kg, respectively ( P < 0.001 for both year-on-year comparisons). At 2.5 years, intragastric balloon therapy had been successful in 24 participants. At final follow-up (4.8 +/- 1.6 years), 28 had > or = 10 % baseline weight loss, 35 had undergone bariatric surgery (60 % had preoperative mass higher than baseline), and 3 were lost to follow-up; the 34 remaining had lost 1.5 +/- 5.8 kg compared with baseline. During follow-up, 13 had a second intragastric balloon implanted and 13 took sibutramine for short periods. CONCLUSION: Intragastric balloon therapy was relatively innocuous and associated with successful weight loss and maintenance at 2.5 years in a quarter of participants. It represents a valid option for weight loss.

[Role of endoscopy in the management of obscure gastrointestinal bleeding]. / Rôle de l'endoscopie dans la prise en charge des saignements digestifs d'origine obscure.

Obscure gastrointestinal bleeding is defined as a blood loss in the digestive tract without etiology found at upper digestive endoscopy and colonoscopy. Small bowel lesions, in particular angiodysplasias, are the most frequent cause. Endoscopic examination of the small bowel can be performed using an enteroscope (with or without balloon) or a videocapsule. Videocapsule endoscopy is a minimally invasive procedure, and it allows complete small bowel exploration in 80% of cases (vs. 40-80% with balloon-aided enteroscopy). In practice, videocapsule endoscopy is the first line exam, followed by enteroscopy for biopsy sampling or treatment. In case of completely negative investigations and persistent bleeding, videocapsule endoscopy may be repeated, generally after repeat upper digestive endoscopy and colonoscopy.

[Endoscopic management of benign biliary strictures]. / Prise en charge endoscopique des sténoses billaires bénignes.

Endoscopic management of benign biliary strictures has significantly changed in recent years. Excluding a malignant etiology remains the first, critical, step; significant progress is being made to increase diagnostic accuracy of bile duct stricture sampling, although negative predictive value does not reach 100%. The currently preferred treatment consists of stricture dilation followed by placement of multiple temporary plastic stents. Drawbacks of this technique include repetition of endoscopic procedures and a small risk of cholangitis. Larger diameter covered self-expandable metal biliary stents seem to be a promising alternative. In this review, we will discuss the various etiologies of benign biliary strictures, their clinical presentation, the diagnostic tools and the endoscopic treatment.
