The aims of the study were to compare the procedure times, benefits, and safety of same-day BDE and conventional serial endoscopic examination (SEE). Patients and Methods All the patients undergoing evaluation with either BDE or SEE were prospectively enrolled at Ramaiah Medical College and Hospitals, Bangalore, from 1st December 2020 to 31st May 2021. EGD was immediately followed by colonoscopy in BDE. In SEE, EGD was followed by colonoscopy in 1 or 2 days. Clinical data and results were collected and evaluated. Results Two hundred consecutive patients who consented for BDE were enrolled in the study. The mean ± standard deviation (range) age of the patients was 45 ± 14.5 (22-60) years. Majority (124 [62%]) were men. The outcome measures of Boston Bowel Preparation Scale with the excellent/good preparation score and polyp detection rate were similar in both groups (p = 0.4). The total procedure time was significantly higher in the SEE group than in the BDE (p < 0.001). There were no adverse events noted in the study. The overall patient experience and satisfaction were higher in BDE than in SEE without any difference in the quality of the procedures (p < 0.001). Patients with weight loss and anemia were more likely to have a positive test result than the patients with abdominal pain and diarrhea. Conclusions In conclusion, same-day BDE is advised for patients with anemia and weight loss which can reduce the number of hospital visits and improve patient satisfaction in COVID times.","PeriodicalId":43098,"journal":{"name":"Journal of Digestive Endoscopy","volume":"13 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"57973790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Endoscopy plays an all-encompassing role in the diagnosis and management of EMDs including achalasia cardia. The focus on in-vogue third-space endoscopic procedures such as per-oral endoscopic myotomy often digresses the important role of endoscopy. Endoscopic evaluation forms the part of standard first-line evaluation of any dysphagia and serves to rule out a secondary cause such as an esophagogastric junction malignancy and eosinophilic esophagitis. Moreover, endoscopic evaluation may itself provide corroborative evidence that may contribute to the diagnosis of the motility disorder. Achalasia cardia may present with a wide spectrum of endoscopic findings from being entirely normal and the well-known and pathognomonic dilated sigmoid-shaped esophagus with food residue, to lesser-known ornate signs. The evidence on the role of endosonography in EMDs is conflicting and largely restricted to evaluation of pseudoachalasia. High-resolution manometry (HRM) remains the gold standard in the diagnosis of EMDs. Endoscopists must also keep abreast of the latest iteration of the Chicago classification version 4.0, which differs significantly from its predecessor in being more stringent in making diagnosis of esophagogastric junction outflow obstruction and disorders of peristalsis since these manometric findings may be seen in normal individuals and may be mimicked by opioid use and gastroesophageal reflux. The latest rendition also includes the use of provocative maneuvers and testing in both supine and sitting posture. Despite being the gold standard, there are certain lacunae in the use and interpretation of the Chicago classification of which the users should be well aware. Emerging technologies such as functional lumen imaging probe and planimetry, and timed barium esophagogram fill the lacuna in diagnosis of these motility disorders, which at times is beyond the resolution of HRM.","PeriodicalId":43098,"journal":{"name":"Journal of Digestive Endoscopy","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43832912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, several reports have confirmed higher incidence of gastroesophageal reflux (GER) following POEM. This review evaluates the current evidence regarding post-POEM GER, critically examines the potential contributing factors responsible for GER, limitations of the current available functional testing, and precautions and preventive measures, and provides future directions for research. Factors conclusively contributing to increased post-POEM GER include injury to the sling fibers of the lower esophageal sphincter, length of gastric myotomy > 2 cm, and others. Historically, these same factors have been implicated for development of GER after surgical (laparoscopic) myotomy. Although less invasive, optimal technique of POEM may be important to control post-POEM GER. Most post-POEM GER occurs during the immediate post-POEM period, is mild, and is easily treatable using proton-pump inhibitors. GER incidence plateaus at 2 years and is comparable to that after LHM. Patients should therefore be prescribed proton-pump inhibitors for at least 2 years. Antireflux procedures (ARPs) are infrequently required in these patients as the incidence of refractory GER is low. Novel ARPs have been recently described and are currently under evaluation. Conclusive diagnosis of GER is a clinical challenge. Most patients are asymptomatic, and GER is diagnosed only on abnormal esophageal acid exposure (EAE). Studies have demonstrated that current measures to diagnose GER are inadequate, inaccurate, and cannot differentiate between true GER and abnormal EAE due to food fermentation in the distal esophagus. The Lyon Consensus criteria should be implemented for confirmation of diagnosis of GER. Finally, the review recommends an evidence-based clinical algorithm for evaluation and management of post-POEM GER and provides guidelines for future research in this field.","PeriodicalId":43098,"journal":{"name":"Journal of Digestive Endoscopy","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45567178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is an audit of endoscopy findings in a community set up using a Mobile Endoscopy Unit (MEU). Patients' details were collected in a pre-designed questionnaire.
