Peroral endoscopic myotomy (POEM) does not include any antireflux procedure, resulting in a certain risk of iatrogenic gastroesophageal reflux disease (GERD). The aim of the present study was to evaluate the incidence of iatrogenic GERD after POEM and identify preoperative, perioperative and postoperative factors associated with GERD. ⋯ Preoperative, perioperative or postoperative factors minimally correlated with GERD after POEM. Clinically relevant GERD was identified in less than one-third of patients, but all patients were well controlled with medical therapy.

Management of patients on antithrombotic therapy undergoing endoscopic procedures can be challenging. Although guidelines from major gastrointestinal endoscopy societies provide useful recommendations in this regard, data are limited concerning the bleeding risk of new complex endoscopic procedures and the management of novel anticoagulants in patients needing invasive procedures. The approach to the management of antithrombotic therapy often needs to be formulated on an individual basis, especially in patients with high thrombotic risk undergoing a high-risk endoscopic procedure. ⋯ If possible, elective procedures with high bleeding risk should be delayed in patients on antithrombotic therapy for conditions with high thrombotic risk. If high-risk procedures cannot be delayed in these patients, thienopyridines, traditional and novel anticoagulants are usually withheld, whereas aspirin withdrawal is decided on a case by case basis. In patients with high thrombotic risk, communication with the prescribing clinician before proceeding to procedures with high bleeding risk is particularly important in optimizing the peri-procedural management plan of antithrombotic therapy.

Multicenter Study
Safety and benefits of self-expandable metallic stents with chemotherapy for malignant gastric outlet obstruction.
The influence of chemotherapy on placement of self-expandable metallic stents (SEMS) for malignant gastric outlet obstruction (MGOO) has not been evaluated extensively. We investigated the influence of chemotherapy on the clinical outcomes of SEMS placement for MGOO. ⋯ Various cancer patients with MGOO can undergo SEMS placement safely regardless of chemotherapy, and concurrent chemotherapy after stent placement can prolong survival time, although re-intervention and stent migration may be increased.

Randomized Controlled Trial Comparative Study
Efficacy of carbon dioxide versus air insufflation according to different sedation protocols during therapeutic endoscopic retrograde cholangiopancreatography: prospective, randomized, double-blind study.
Therapeutic endoscopic retrograde cholangiopancreatography (ERCP) tends to require considerable air insufflation, which results in abdominal pain or distension. We investigated the efficacy of carbon dioxide (CO2 ) compared with air insufflation when using two different sedation protocols in therapeutic ERCP. ⋯ CO2 with BPS showed the lowest VAS score for early abdominal pain, distension and GVS, and had a higher score for overall satisfaction for sedation.
