RESUMEN
This ESGE Position Statement defines the expected value of artificial intelligence (AI) for the diagnosis and management of gastrointestinal neoplasia within the framework of the performance measures already defined by ESGE. This is based on the clinical relevance of the expected task and the preliminary evidence regarding artificial intelligence in artificial or clinical settings. MAIN RECOMMENDATIONS:: (1) For acceptance of AI in assessment of completeness of upper GI endoscopy, the adequate level of mucosal inspection with AI should be comparable to that assessed by experienced endoscopists. (2) For acceptance of AI in assessment of completeness of upper GI endoscopy, automated recognition and photodocumentation of relevant anatomical landmarks should be obtained in ≥90% of the procedures. (3) For acceptance of AI in the detection of Barrett's high grade intraepithelial neoplasia or cancer, the AI-assisted detection rate for suspicious lesions for targeted biopsies should be comparable to that of experienced endoscopists with or without advanced imaging techniques. (4) For acceptance of AI in the management of Barrett's neoplasia, AI-assisted selection of lesions amenable to endoscopic resection should be comparable to that of experienced endoscopists. (5) For acceptance of AI in the diagnosis of gastric precancerous conditions, AI-assisted diagnosis of atrophy and intestinal metaplasia should be comparable to that provided by the established biopsy protocol, including the estimation of extent, and consequent allocation to the correct endoscopic surveillance interval. (6) For acceptance of artificial intelligence for automated lesion detection in small-bowel capsule endoscopy (SBCE), the performance of AI-assisted reading should be comparable to that of experienced endoscopists for lesion detection, without increasing but possibly reducing the reading time of the operator. (7) For acceptance of AI in the detection of colorectal polyps, the AI-assisted adenoma detection rate should be comparable to that of experienced endoscopists. (8) For acceptance of AI optical diagnosis (computer-aided diagnosis [CADx]) of diminutive polyps (≤5 mm), AI-assisted characterization should match performance standards for implementing resect-and-discard and diagnose-and-leave strategies. (9) For acceptance of AI in the management of polyps ≥â6âmm, AI-assisted characterization should be comparable to that of experienced endoscopists in selecting lesions amenable to endoscopic resection.

The European Society of Gastrointestinal Endoscopy (ESGE) has developed performance measures and established a framework for quality assessment for gastrointestinal endoscopy in Europe. Most national societies actively undertake initiatives to implement and explicitly endorse these quality indicators. Given this, ESGE proposes that, at a national level, strong leadership should exist to disseminate and implement quality parameters. Thus, understanding the potential barriers that may vary locally is of paramount importance. ESGE suggests that each national society should prioritize quality and standards of care in gastrointestinal endoscopy in their activities and should survey/understand which measures are a local priority to their members and make measuring quality intrinsic to daily endoscopy practice.

BACKGROUND: Although bowel preparation before colonoscopy and capsule endoscopy is widely evaluated and usually follows established guidelines, a standard preparation regime for peroral small bowel enteroscopy is yet to be defined.The aim of the present study was to compare small bowel preparation with polyethylene glycol (PEG) and "fasting only" (FO) before peroral single-balloon enteroscopy (SBE). STUDY: We compared small bowel preparation with PEG versus "FO" for peroral SBE in a randomized European multicenter trial. Patients' and procedural characteristics were documented and carefully analyzed. Primary endpoint was the oral intubation depth of the small bowel. A modified Boston preparation scale was used to assess bowel cleansing as a secondary endpoint. RESULTS: In total, 43 patients were enrolled in this study (FO group: n=25; PEG group: n=18). In both groups, patients' characteristics were comparable. The indications for oral enteroscopy were equally distributed in both groups (P=0.894). The oral intubation depth was significantly higher in the PEG versus the FO group (261±87 vs. 203±66 cm; P=0.019; mean±SD), while the quality of bowel preparation was equally sufficient in both groups [complete visualization of the mucosa (Boston preparation scale) 83% versus 76% (P=1.000)]. CONCLUSIONS: Small bowel preparation with PEG for SBE yields significantly deeper intubation as compared with "FO" preparation. As patient comfort and safety was similar in both groups, PEG preparation might be favored, especially if deep intubation of the small bowel is desired. For patients requiring visualization of the proximal jejunum, a FO preparation seems to be sufficient.

The European Society of Gastrointestinal Endoscopy (ESGE) together with the United European Gastroenterology (UEG) recently developed a short list of performance measures for small-bowel endoscopy (i.âe. small-bowel capsule endoscopy and device-assisted enteroscopy) with the final goal of providing endoscopy services across Europe with a tool for quality improvement. Six key performance measures for both small-bowel capsule endoscopy and for device-assisted enteroscopy were selected for inclusion, with the intention being that practice at both a service and endoscopist level should be evaluated against them. Other performance measures were considered to be less relevant, based on an assessment of their overall importance, scientific acceptability, and feasibility. Unlike lower and upper gastrointestinal endoscopy, where performance measures had already been identified, this is the first time that small-bowel endoscopy quality measures have been proposed.
RESUMEN
SMALL-BOWEL CAPSULE ENDOSCOPY (SBCE): 1: ESGE recommends that prior to SBCE patients ingest a purgative (2âL of polyethylene glycol [PEG]) for better visualization.Strong recommendation, high quality evidence.However, the optimal timing for taking purgatives is yet to be established. 2: ESGE recommends that SBCE should be performed as an outpatient procedure if possible, since completion rates are higher in outpatients than in inpatients.Strong recommendation, moderate quality evidence. 3: ESGE recommends that patients with pacemakers can safely undergo SBCE without special precautions.Strong recommendation, low quality evidence. 4: ESGE suggests that SBCE can also be safely performed in patients with implantable cardioverter defibrillators and left ventricular assist devices.Weak recommendation, low quality evidence. 5: ESGE recommends the acceptance of qualified nurses and trained technicians as prereaders of capsule endoscopy studies as their competency in identifying pathology is similar to that of medically qualified readers. The responsibility of establishing a diagnosis must however remain with the attending physician.Strong recommendation, moderate quality evidence. 6: ESGE recommends observation in cases of asymptomatic capsule retention.Strong recommendation, moderate quality evidence.In cases where capsule retrieval is indicated, ESGE recommends the use of device-assisted enteroscopy as the method of choice.Strong recommendation, moderate quality evidence. DEVICE-ASSISTED ENTEROSCOPY (DAE): 1: ESGE recommends performing diagnostic DAE as a day-case procedure in patients without significant underlying co-morbidities; in patients with co-morbidities and/or those undergoing a therapeutic procedure, an inpatient stay is recommended.Strong recommendation, low quality evidenceThe choice between different settings also depends on sedation protocols.Strong recommendation, low quality evidence. 2: ESGE suggests that conscious sedation, deep sedation, and general anesthesia are all acceptable alternatives: the choice between them should be governed by procedure complexity, clinical factors, and local organizational protocols.Weak recommendation, low quality evidence. 3: ESGE recommends that the findings of previous diagnostic investigations should guide the choice of insertion route.Strong recommendation, moderate quality evidence.If the location of the small-bowel lesion is unknown or uncertain, ESGE recommends that the antegrade route should be generally preferred.Strong recommendation, low quality evidence.In the setting of massive overt bleeding, ESGE recommends an initial antegrade approach.Strong recommendation, low quality evidence. 4: ESGE recommends that, for balloon-assisted enteroscopy (i.âe., single-balloon enteroscopy [SBE] and double-balloon enteroscopy [DBE]), small-bowel insertion depth should be estimated by counting net advancement of the enteroscope during the insertion phase, with confirmation of this estimate during withdrawal.Strong recommendation, low quality evidence.ESGE recommends that, for spiral enteroscopy, insertion depth should be estimated during withdrawal.Strong recommendation, moderate quality evidence. Since the calculated insertion depth is only a rough estimate, ESGE recommends placing a tattoo to mark the identified lesion and/or the deepest point of insertion.Strong recommendation, low quality evidence. 5: ESGE recommends that all endoscopic therapeutic procedures can be undertaken at the time of DAE.Strong recommendation, moderate quality evidence.Moreover, when therapeutic interventions are performed, additional specific safety measures are needed to prevent complications.Strong recommendation, high quality evidence.

The European Society of Gastrointestinal Endoscopy (ESGE) and United European Gastroenterology present a list of key performance measures for endoscopy services. We recommend that these performance measures be adopted by all endoscopy services across Europe. The measures include those related to the leadership, organization, and delivery of the service, as well as those associated with the patient journey. Each measure includes a recommendation for a minimum and target standard for endoscopy services to achieve. We recommend that all stakeholders in endoscopy take note of these ESGE endoscopy services performance measures to accelerate their adoption and implementation. Stakeholders include patients and their advocacy groups; service leaders; staff, including endoscopists; professional societies; payers; and regulators.

To develop standards for high quality in gastrointestinal (GI) endoscopy, the European Society of Gastrointestinal Endoscopy (ESGE) has established the ESGE Quality Improvement Committee. A prerequisite for quality assurance and improvement for all GI endoscopy procedures is state-of-the-art integrated digital reporting systems for standardized documentation of the procedures. The current paper describes the ESGE's viewpoints on the requirements for high-quality endoscopy reporting systems in GI endoscopy. Recommendations 1 Endoscopy reporting systems must be electronic. 2 Endoscopy reporting systems should be integrated into hospitals' patient record systems. 3 Endoscopy reporting systems should include patient identifiers to facilitate data linkage to other data sources. 4 Endoscopy reporting systems shall restrict the use of free-text entry to a minimum, and be based mainly on structured data entry. 5 Separate entry of data for quality or research purposes is discouraged. Automatic data transfer for quality and research purposes must be facilitated. 6 Double entry of data by the endoscopist or associate personnel is discouraged. Available data from outside sources (administrative or medical) must be made available automatically. 7 Endoscopy reporting systems shall facilitate the inclusion of information on histopathology of detected lesions, patient satisfaction, adverse events, and surveillance recommendations. 8 Endoscopy reporting systems must facilitate easy data retrieval at any time in a universally compatible format. 9 Endoscopy reporting systems must include data fields for key performance indicators as defined by quality improvement committees. 10 Endoscopy reporting systems must facilitate changes in indicators and data entry fields as required by professional organizations.

The European Society of Gastrointestinal Endoscopy (ESGE) and United European Gastroenterology (UEG) have a vision to create a thriving community of endoscopy services across Europe, collaborating with each other to provide high quality, safe, accurate, patient-centered and accessible endoscopic care. Whilst the boundaries of what can be achieved by advanced endoscopy are continually expanding, we believe that one of the most fundamental steps to achieving our goal is to raise the quality of everyday endoscopy. The development of robust, consensus- and evidence-based key performance measures is the first step in this vision.ESGE and UEG have identified quality of endoscopy as a major priority. This paper explains the rationale behind the ESGE Quality Improvement Initiative and describes the processes that were followed. We recommend that all units develop mechanisms for audit and feedback of endoscopist and service performance using the ESGE performance measures that will be published in future issues of this journal over the next year. We urge all endoscopists and endoscopy services to prioritize quality and to ensure that these performance measures are implemented and monitored at a local level, so that we can provide the highest possible care for our patients.

Background and study aim: Gastrointestinal endoscopy is a rapidly evolving research field. The European Society of Gastrointestinal Endoscopy (ESGE) plays a key role in shaping opinion and endoscopy activity throughout Europe and further afield. Establishing key unanswered questions within the field of endoscopy and prioritizing those that are important enables researchers and funders to appropriately allocate resources. Methods: Over 2 years, the ESGE Research Committee gathered information on research priorities and refined them through a modified Delphi approach. Consultations were held with the ESGE Governing Board and Quality Improvement Committee to identify important unanswered questions. Research workshops were held at the 21st United European Gastroenterology Week. Research questions were refined by the ESGE Research Committee and Governing Board, compiled into an online survey, and distributed to all ESGE members, who were invited to rank each question by priority. Results: The final questionnaire yielded 291 responses from over 60 countries. The three countries with the highest response rates were Spain, Italy, and United Kingdom. Most responders were from teaching hospitals (62â%) and were specialist endoscopists (51â%). Responses were analyzed with weighted rankings, resulting in prioritization of 26 key unanswered questions. The top ranked generic questions were: 1) How do we define the correct surveillance interval following endoscopic diagnosis? 2) How do we correctly utilize advanced endoscopic imaging? 3) What are the best markers of endoscopy quality? Conclusion: Following this comprehensive process, the ESGE has identified and ranked the key unanswered questions within the field of gastrointestinal endoscopy. Researchers, funders, and journals should prioritize studies that seek to answer these important questions.

BACKGROUND AND STUDY AIMS: Hemostatic powders have been introduced to improve the management of gastrointestinal (GI) bleeding and to extend the variety of tools available for emergency endoscopy. The aim of the present pilot study was to evaluate the indication profiles and the short-term outcome of EndoClot. PATIENTS, MATERIALS AND METHODS: In a prospective observational pilot study patients with acute nonvariceal GI bleeding were included. Primary or secondary application of EndoClot was assessed. Hemoglobin, prothrombine time and platelets were documented before and after hemostasis. The efficacy of EndoClot was assessed 72 hours and 1 week after application. RESULTS: Seventy patients with acute GI bleeding were recruited into the study. Eighty-three percent (58/70) of the patients had upper and 17% (12/70) had lower GI bleeding. In the upper GI tract treatment success was achieved in 64% (30/47, 95% confidence interval, 50%-76%) after primary use and in all patients, when used after established techniques had failed (95% confidence interval, 70%-100%). In lower GI bleeding hemostasis was achieved in 83% of cases (10/12, 95% confidence interval 54%-97%). Rebleeding occurred in 11% (8/70), in 10% EndoClot served as a bridge to surgery (7/70). CONCLUSIONS: EndoClot expanded the therapeutic options in the management of GI bleeding. It was applicable as a monotherapy or in combination with other techniques from oozing bleeding type or lower. It was most effective in diffuse or extensive bleeding activity or when access to the bleeding vessel was difficult. EndoClot can be applied as a bridge to surgery when classical methods of hemostasis have failed.

This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). The Guideline was also reviewed and endorsed by the British Society of Gastroenterology (BSG). It addresses the roles of small-bowel capsule endoscopy and device-assisted enteroscopy for diagnosis and treatment of small-bowel disorders. Main recommendations 1 ESGE recommends small-bowel video capsule endoscopy as the first-line investigation in patients with obscure gastrointestinal bleeding (strong recommendation, moderate quality evidence). 2 In patients with overt obscure gastrointestinal bleeding, ESGE recommends performing small-bowel capsule endoscopy as soon as possible after the bleeding episode, optimally within 14 days, in order to maximize the diagnostic yield (strong recommendation, moderate quality evidence). 3 ESGE does not recommend the routine performance of second-look endoscopy prior to small-bowel capsule endoscopy; however whether to perform second-look endoscopy before capsule endoscopy in patients with obscure gastrointestinal bleeding or iron-deficiency anaemia should be decided on a case-by-case basis (strong recommendation, low quality evidence). 4 In patients with positive findings at small-bowel capsule endoscopy, ESGE recommends device-assisted enteroscopy to confirm and possibly treat lesions identified by capsule endoscopy (strong recommendation, high quality evidence). 5 ESGE recommends ileocolonoscopy as the first endoscopic examination for investigating patients with suspected Crohn's disease (strong recommendation, high quality evidence). In patients with suspected Crohn's disease and negative ileocolonoscopy findings, ESGE recommends small-bowel capsule endoscopy as the initial diagnostic modality for investigating the small bowel, in the absence of obstructive symptoms or known stenosis (strong recommendation, moderate quality evidence).ESGE does not recommend routine small-bowel imaging or the use of the PillCam patency capsule prior to capsule endoscopy in these patients (strong recommendation, low quality evidence). In the presence of obstructive symptoms or known stenosis, ESGE recommends that dedicated small bowel cross-sectional imaging modalities such as magnetic resonance enterography/enteroclysis or computed tomography enterography/enteroclysis should be used first (strong recommendation, low quality evidence). 6 In patients with established Crohn's disease, based on ileocolonoscopy findings, ESGE recommends dedicated cross-sectional imaging for small-bowel evaluation since this has the potential to assess extent and location of any Crohn's disease lesions, to identify strictures, and to assess for extraluminal disease (strong recommendation, low quality evidence). In patients with unremarkable or nondiagnostic findings from such cross-sectional imaging of the small bowel, ESGE recommends small-bowel capsule endoscopy as a subsequent investigation, if deemed to influence patient management (strong recommendation, low quality evidence). When capsule endoscopy is indicated, ESGE recommends use of the PillCam patency capsule to confirm functional patency of the small bowel (strong recommendation, low quality evidence). 7 ESGE strongly recommends against the use of small-bowel capsule endoscopy for suspected coeliac disease but suggests that capsule endoscopy could be used in patients unwilling or unable to undergo conventional endoscopy (strong recommendation, low quality evidence).

BACKGROUND AND STUDY AIMS: Carbon dioxide (CO2) insufflation has previously been shown to have advantages over air insufflation in terms of procedure-related pain and oral insertion depth during double-balloon enteroscopy. The aim of this prospective study was to evaluate the performance of CO2 vs. air insufflation during single-balloon enteroscopy. PATIENTS AND METHODS: This study was a randomized European multicenter trial (ClinicalTrials.gov: NCT01524055). Patients and endoscopists were blinded to the type of insufflation gas used. Patient discomfort during and after the procedure was scored using a visual analog scale. RESULTS: A total of 107 patients were enrolled in the study (52 in the CO2 group and 55 in the air group). Patient characteristics were comparable in both groups. The mean (±SD) oral intubation depth was not significantly deeper in the CO2 group vs. the air group (254±80 vs. 238±55 cm; P=0.726). However, in patients with previous abdominal surgery, oral intubation depth was significantly higher in the CO2 group compared with the air group (258±84 vs. 192±42 cm; P<0.05). In patients undergoing SBE via the anal approach, CO2 showed no significant difference in intubation depth compared with air insufflation (86±67 vs. 110±68 cm; P=0.155). The diagnostic yield was comparable (CO2 67%; air 73%). Procedure times, dosage of sedation, and therapeutic interventions did not differ between the two groups. Patients in the CO2 group reported less pain than those in the air group. CONCLUSIONS: This study demonstrated an advantage of using CO2 insufflation during single-balloon enteroscopy in patients with a history of previous abdominal surgery. Overall, single-balloon enteroscopy was a well-tolerated procedure that may benefit from the use of CO2 insufflation to reduce post-procedural pain.

OBJECTIVE: Bile duct stones that cannot be removed endoscopically are still a challenge in interventional gastroenterology. Extracorporeal shockwave lithotripsy (ESWL) with subsequent endoscopic extraction of residual fragments is an established treatment option if other endoscopic means are not successful. Our study aimed to investigate the efficacy and safety of ESWL for clearance of refractory bile duct stones. MATERIAL AND METHODS: A total of 73 consecutive patients treated for refractory choledocholithiasis with ESWL were retrospectively analyzed. Success and complication rates were calculated. RESULTS: Complete stone clearance was achieved in 66 cases (90%). Patients with complete clearance had a significantly lower body mass index or BMI (25.55 ± 5.01 kg/m² vs. 31.60 ± 6.26 kg/m², p = 0.035) and needed less ESWL treatments (3.61 ± 1.87 vs. 5.00 ± 1.63, p = 0.048). A relevant drop of hemoglobin occurred significantly more often in the group with partial clearance (43% vs. 6%, p = 0.005). CONCLUSIONS: ESWL proves to be an excellent clearing approach to refractory bile duct stones with high success rates. However, obesity is one risk factor for ESWL failure and higher procedural hazard.

BACKGROUND: Hydrogen breath tests are noninvasive procedures frequently applied in the diagnostic workup of functional gastrointestinal disorders. Here, we review hydrogen breath test results and the occurrence of lactose, fructose and sorbitol malabsorption in pediatric patients; and determine the significance of the findings and the outcome of patients with carbohydrate malabsorption. METHODS: We included 206 children (88 male, 118 female, median age 10.7 years, range 3-18 years) with a total of 449 hydrogen breath tests (lactose, n = 161; fructose, n = 142; sorbitol, n = 146) into a retrospective analysis. Apart from test results, we documented symptoms, the therapeutic consequences of the test, the outcome and the overall satisfaction of the patients and families. RESULTS: In total, 204 (46%) of all breath tests were positive. Long-term follow-up data could be collected from 118 patients. Of 79 patients (67%) who were put on a diet reduced in lactose, fructose and/or sorbitol, the majority (92%, n = 73) reported the diet to be strict and only 13% (n = 10) had no response to diet. Most families (96%, n = 113) were satisfied by the test and the therapy. There were only 21 tests (5%) with a borderline result because the criteria for a positive result were only partially met. CONCLUSIONS: Hydrogen breath tests can be helpful in the evaluation of children with gastrointestinal symptoms including functional intestinal disorders. If applied for a variety of carbohydrates but only where indicated, around two-third of all children have positive results. The therapeutic consequences are successfully relieving symptoms in the vast majority of patients.

BACKGROUND: Pancreatitis is a potentially life-threatening condition frequently accompanied by peri-pancreatic fluid collections (PPFC), such as pseudocysts or pancreatic necrosis. Aspiration of PPFCs during EUS interventions for microbiologic analysis is still rarely performed in clinical routine. OBJECTIVE: To evaluate the role of routine microbiologic analysis of PPFCs and its impact on antibiotic therapy in patients with pancreatitis. DESIGN: Prospective, observational, multicenter study. SETTING: Four treatment centers. PATIENTS: A total of 44 consecutive patients who presented for endoscopic treatment of PPFCs were included. INTERVENTION: Concomitantly, PPFC during intervention and concomitant blood cultures were obtained. MAIN OUTCOME MEASUREMENTS: Microbiologic examination of PPFCs and blood samples. RESULTS: Colonization of PPFCs was found in 59% of PPFC cultures, whereas all but 2 concomitant blood cultures showed no microbial growth. Risk factors for a colonization were the presence of necrosis (P = .006), acute pancreatitis (P = .033), leukocytosis (P = .001), elevated C-reactive protein levels (P = .003), fever (P = .02), turbid material (P = .031), and longer hospital stay (P = .003). In 23 patients with fluid colonization despite empiric antibiotic therapy, the treatment had to be adjusted in 18 patients (78%) according to the observed antibiotic susceptibility profile. LIMITATIONS: Contamination cannot be totally excluded. CONCLUSION: The microbiologic colonization of PPFCs in patients with pancreatitis is common. Only the direct microbiologic analysis of PPFCs, but not of blood cultures, is useful to optimize an effective antibiotic therapy in patients with pancreatitis.

PURPOSE: This study aims to compare double- (DBE) and single-balloon enteroscopy (SBE) in small bowel disorders with respect to procedural performance and clinical impact. METHODS: This retrospective analysis at a tertial referral center included 1,052 DBEs and 515 SBEs performed in 904 patients over 7 years. Procedural and patients' characteristics were precisely analyzed. RESULTS: Significantly more patients with anemia and gastrointestinal bleeding were investigated by DBE (P < 0.01). Oral insertion depth and length of investigated small bowel in the combined approach were significantly higher in the DBE compared to the SBE group (245 ± 65.3 vs. 218 ± 62.6 and 355 ± 101.9 vs. 319 ± 91.2, respectively; P < 0.001, each). By analyzing only recent years of enteroscopy (2008-2011), no difference in small bowel visualization could be observed. The anal insertion depths and complete enteroscopy rates (CER) were comparable. Procedure times were significantly shorter within the SBE procedure (oral: 50 vs. 40 min; anal: 55 vs. 46 min, P < 0.001) and the usage of sedation was significantly less (propofol: P < 0.001; pethidine: P < 0.05). Diagnostic yield was significantly higher in the SBE, compared to the DBE group (61.7 vs. 48.2 %; P < 0.001). The rate of severe adverse events was close to zero. CONCLUSION: Both enteroscopy techniques are safe diagnostic tools and proved to be indispensable in the daily gastroenterological practice. The lower insertion depths, but higher diagnostic yield, of SBE may reflect the more focused selection of patients scheduled for small bowel diagnostics in recent years.

BACKGROUND: Despite recent advances in imaging techniques, adequate classification of esophageal lesions is still challenging. Accurate staging of tumors of the esophagus is a precondition for targeted therapy. In this retrospective, multicenter study, we report the role of high-frequency endoscopic ultrasound (EUS) catheter probes in pretherapeutic staging of esophageal neoplasms and thus guiding treatment decisions. METHODS: A total of 143 patients (mean age of 63.8 ± 10.7 years) with esophageal carcinoma were recruited from five German centers (Münster, Oldenburg, Hannover, Wiesbaden, and Lüneburg). Tumor type was adenocarcinoma in 112 (78 %) cases and squamous cell carcinoma in 31 (22 %). Tumor localization was as follows: proximal 3, mid esophagus 7, and distal third 133. Histological correlation either through EMR or surgery was available. In all patients, pretherapeutic uT and uN classifications were compared to pT/pN classification obtained from surgically (esophagectomy, n = 93) or endoscopically (EMR, n = 50) resected tissue. RESULTS: Overall, accuracy of uT classification was 60 % and of uN classification was 74 %. Sensitivity, specificity, and accuracy rates for local tumor extension were as follows (%): T1: 68/97/83; T2: 39/84/75; T3: 72/81/79; T4: 13/97/93; T1/2: 73/81/75; T3/4: 78/82/81. Relating to positive lymph node detection, sensitivity and specificity were 76 and 71 %, respectively. CONCLUSIONS: Miniprobe EUS is an established method for the staging of esophageal tumors. Our large multicenter cohort shows a solid accuracy of miniprobe EUS with respect to differentiating locally advanced from limited cancer and assisting to determine the treatment regimen in the era of neoadjuvant therapy; consequently, 78 % of patients would have been assigned to the adequate therapeutic regimen, whereas 11 % of patients would have been overtreated and 11 % undertreated.
