Main Recommendations Prophylaxis 1 ESGE recommends routine rectal administration of 100 mg of diclofenac or indomethacin immediately before endoscopic retrograde cholangiopancreatography (ERCP) in all patients without contraindications to nonsteroidal anti-inflammatory drug administration.Strong recommendation, moderate quality evidence. 2 ESGE recommends prophylactic pancreatic stenting in selected patients at high risk for post-ERCP pancreatitis (inadvertent guidewire insertion/opacification of the pancreatic duct, double-guidewire cannulation).Strong recommendation, moderate quality evidence. 3 ESGE suggests against routine endoscopic biliary sphincterotomy before the insertion of a single plastic stent or an uncovered/partially covered self-expandable metal stent for relief of biliary obstruction.Weak recommendation, moderate quality evidence. 4 ESGE recommends against the routine use of antibiotic prophylaxis before ERCP.Strong recommendation, moderate quality evidence. 5 ESGE suggests antibiotic prophylaxis before ERCP in the case of anticipated incomplete biliary drainage, for severely immunocompromised patients, and when performing cholangioscopy.Weak recommendation, moderate quality evidence. 6 ESGE suggests tests of coagulation are not routinely required prior to ERCP for patients who are not on anticoagulants and not jaundiced.Weak recommendation, low quality evidence. Treatment 7 ESGE suggests against salvage pancreatic stenting in patients with post-ERCP pancreatitis.Weak recommendation, low quality evidence. 8 ESGE suggests temporary placement of a biliary fully covered self-expandable metal stent for post-sphincterotomy bleeding refractory to standard hemostatic modalities.Weak recommendation, low quality evidence. 9 ESGE suggests to evaluate patients with post-ERCP cholangitis by abdominal ultrasonography or computed tomography (CT) scan and, in the absence of improvement with conservative therapy, to consider repeat ERCP. A bile sample should be collected for microbiological examination during repeat ERCP.Weak recommendation, low quality evidence.

IMPORTANCE Case series suggest favorable results of peroral endoscopic myotomy (POEM) for treatment of patients with achalasia. Data comparing POEM with pneumatic dilation, the standard treatment for patients with achalasia, are lacking. OBJECTIVE To compare the effects of POEM vs pneumatic dilation as initial treatment of treatment-naive patients with achalasia. DESIGN, SETTING, AND PARTICIPANTS This randomized multicenter clinical trial was conducted at 6 hospitals in the Netherlands, Germany, Italy, Hong Kong, and the United States. Adult patients with newly diagnosed achalasia and an Eckardt score greater than 3 who had not undergone previous treatment were included. The study was conducted between September 2012 and July 2015, the duration of follow-up was 2 years after the initial treatment, and the final date of follow-up was November 22, 2017. INTERVENTIONS Randomization to receive POEM (n = 67) or pneumatic dilation with a 30-mm and a 35-mm balloon (n = 66), with stratification according to hospital. MAIN OUTCOMES AND MEASURES The primary outcome was treatment success (defined as an Eckardt score Յ3 and the absence of severe complications or re-treatment) at the 2-year follow-up. A total of 14 secondary end points were examined among patients without treatment failure, including integrated relaxation pressure of the lower esophageal sphincter via high-resolution manometry, barium column height on timed barium esophagogram, and presence of reflux esophagitis. RESULTS Of the 133 randomized patients, 130 (mean age, 48.6 years; 73 [56%] men) underwent treatment (64 in the POEM group and 66 in the pneumatic dilation group) and 126 (95%) completed the study. The primary outcome of treatment success occurred in 58 of 63 patients (92%) in the POEM group vs 34 of 63 (54%) in the pneumatic dilation group, a difference of 38% ([95% CI, 22%-52%]; P < .001). Of the 14 prespecified secondary end points, no significant difference between groups was demonstrated in 10 end points. There was no significant between-group difference in median integrated relaxation pressure (9.9 mm Hg in the POEM group vs 12.6 mm Hg in the pneumatic dilation group; difference, 2.7 mm Hg [95% CI, −2.1 to 7.5]; P = .07) or median barium column height (2.3 cm in the POEM group vs 0 cm in the pneumatic dilation group; difference, 2.3 cm [95% CI, 1.0-3.6]; P = .05). Reflux esophagitis occurred more often in the POEM group than in the pneumatic dilation group (22 of 54 [41%] vs 2 of 29 [7%]; difference, 34% [95% CI, 12%-49%]; P = .002). Two serious adverse events, including 1 perforation, occurred after pneumatic dilation, while no serious adverse events occurred after POEM. CONCLUSIONS AND RELEVANCE Among treatment-naive patients with achalasia, treatment with POEM compared with pneumatic dilation resulted in a significantly higher treatment success rate at 2 years. These findings support consideration of POEM as an initial treatment option for patients with achalasia.

Main Recommendations 1 ESGE recommends against diagnostic/therapeutic papillectomy when adenoma is not proven.Strong recommendation, low quality evidence. 2 ESGE recommends endoscopic ultrasound and abdominal magnetic resonance cholangiopancreatography (MRCP) for staging of ampullary tumors.Strong recommendation, low quality evidence. 3 ESGE recommends endoscopic papillectomy in patients with ampullary adenoma without intraductal extension, because of good results regarding outcome (technical and clinical success, morbidity, and recurrence).Strong recommendation, moderate quality evidence. 4 ESGE recommends en bloc resection of ampullary adenomas up to 20–30 mm in diameter to achieve R0 resection, for optimizing the complete resection rate, providing optimal histopathology, and reduction of the recurrence rate after endoscopic papillectomy.Strong recommendation, low quality evidence. 5 ESGE suggests considering surgical treatment of ampullary adenomas when endoscopic resection is not feasible for technical reasons (e. g. diverticulum, size > 4 cm), and in the case of intraductal involvement (of > 20 mm). Surveillance thereafter is still mandatory.Weak recommendation, low quality evidence. 6 ESGE recommends direct snare resection without submucosal injection for endoscopic papillectomy.Strong recommendation, moderate quality evidence. 7 ESGE recommends prophylactic pancreatic duct stenting to reduce the risk of pancreatitis after endoscopic papillectomy.Strong recommendation, moderate quality evidence. 8 ESGE recommends long-term monitoring of patients after endoscopic papillectomy or surgical ampullectomy, based on duodenoscopy with biopsies of the scar and of any abnormal area, within the first 3 months, at 6 and 12 months, and thereafter yearly for at least 5 years.Strong recommendation, low quality evidence.

ObjectiveCurrently available methods for small bowel endoscopy are often time consuming; motorised PowerSpiral Enteroscopy (PSE) is a further development of spiral enteroscopy to facilitate the approach to the small bowel. The aim of this bicentric prospective trial was to study feasibility and yield of peroral PSE.DesignConsecutive patients with suspected small bowel disease and indication for antegrade enteroscopy were included in two tertiary referral centres. Primary objective was diagnostic yield of antegrade PSE. Secondary objectives included technical success (defined as successful endoscope insertion at least to ligament of Treitz), depth of maximum insertion (DMI), median insertion time to DMI, rate of therapeutic procedures and adverse events.ResultsDuring a 30-month period, 140 procedures were performed on 132 patients (58 female, 74 male; median age: 68 (20–100) years) under general anaesthesia. Overall diagnostic yield of PSE was 74.2%; with 68.2% of procedures including some form of endotherapy. Technical success rate of PSE was 97%; median DMI was 450 cm (0–600) with a median insertion time to DMI of 25 min (3–122). Antegrade panenteroscopy to the cecum was achieved in 14 cases (10.6%). Overall adverse event (AE) rate was 14.4%; two major serious AEs occurred (1.5%), one delayed perforation, one bleeding from Mallory-Weiss lesion.ConclusionThis pilot clinical trial demonstrates that PSE is effective for diagnostic and therapeutic antegrade enteroscopy and may compare favourably with traditional methods of deep enteroscopy in ease of use and procedural duration. More comparative data are required to assess clinical application and safety of PSE.Trial registration numberNCT02965209
