POEM from A to Z: current perspectives

The "third space endoscopy" or also called "submucosal endoscopy" is a reality we can transfer to our patients since 2010. Various modifications of the submucosal tunneling technique allow access to the submucosa or deeper layers of the gastrointestinal tract. In addition to peroral endoscopic myotomy for the treatment of achalasia, also called esophageal POEM, other variants have emerged that make it possible to treat different esophageal motility disorders, esophageal diverticula, subepithelial tumors of various locations, gastroparesis, reconnection of complete esophageal strictures or even thanks to exceptional endoscopists, pediatric disorders such as Hirschsprung's disease. Although some technical aspects are yet to be standardized, these procedures are becoming widespread worldwide and will likely become the standard treatment of these pathologies soon.

Resumption of activity in gastroenterology departments. Recommendations by SEPD, AEEH, GETECCU and AEG

The set of measures proposed by SEPD, AEEH, GETECCU and AEG are aimed to help departments in their resumption of usual activity. We have prepared a number of practical recommendations regarding patient management and the stepwise resumption of healthcare activity. These recommendations are based on the sparse, changing evidence available, and will be updated in the future according to daily needs and the availability of expendable materials to suit them; in each department they will be implemented depending upon the cumulative incidence of SARS-CoV-2 infection in each region, and the burden the pandemic has represented for each hospital. The general objectives of these recommendations include: (a)To protect our patients against the risks of infection with SARS-CoV-2 and to provide them with high-quality care. (b)To protect all healthcare professionals against the risks of infection with SARS-CoV-2. (c)To resume normal functioning of our departments in a setting of ongoing risk for infection with SARS-CoV-2.

Clinical guidelines for endoscopic mucosal resection of non-pedunculated colorectal lesions

This document summarizes the contents of the Clinical Guidelines for the Endoscopic Mucosal Resection of Non-Pedunculated Colorectal Lesions that was developed by the working group of the Spanish Society of Digestive Endoscopy (GSEED of Endoscopic Resection). This document presents recommendations for the endoscopic management of superficial colorectal neoplastic lesions.

Esophageal capsule endoscopy in patients refusing conventional endoscopy for the study of suspected esophageal pathology

AIM

Esophageal capsule endoscopy is a well tolerated procedure that does not require sedation and has proved its value for the study of the esophagus. The aim of our study was to assess the feasibility, accuracy, safety and acceptability of esophageal capsule endoscopy for the study of gastroesophageal reflux disease and esophageal varices in patients who refused conventional upper gastrointestinal endoscopy.

PATIENTS AND METHODS

Thirty consecutive examinations performed in 28 patients (15 men/13 women; mean age: 58.5+/-12.4 years; range: 23-87 years) were reviewed. Twenty-five examinations were performed in 23 patients presenting with chronic gastroesophageal reflux disease symptoms and the remaining five were carried out in patients with cirrhosis for screening of esophageal varices. The procedures were done with the new PillCam ESO that harbors two viewing cupules and takes a total of 14 frames/s. Technical data (total recording time, esophageal transit time and Z-line visualization), clinical findings (Savary-Miller grade; presence and characteristics of esophageal varices or portal hypertension gastropathy), and patient's opinion (quality and comfort questionnaire) were analyzed.

RESULTS

All the patients ingested and excreted the capsule without complications. Two examinations in the gastroesophageal reflux disease group were repeated; one was issued as a follow-up and the other because no images were recorded in the first capsule endoscopy. From the former, only the satisfaction questionnaire was analyzed. Mean total recording time and esophageal transit time were 1224 and 243.79 s, respectively (range: 2-1192 s). Complete study of the Z-line was possible in 23 examinations (23/29; 79.3%). Esophageal erosions were seen in 58.33% (14/24) of the examinations carried out in patients with gastroesophageal reflux disease. Nine out of 14 patients (64.29%) presented with grade I esophagitis and the other five (35.71%) with grade II esophagitis. Among the five patients with cirrhosis, small varices were visualized in one (1/5; 20%), while large varices with red spots were evidenced in the remaining three (3/5; 60%). All four patients showing esophageal varices were found to have portal hypertension gastropathy. In most examinations, patients found the capsule easy to swallow (28/30; 93.33%), asymptomatic (29/30; 96.66%), evaluated the procedure as comfortable (29/30; 96.66%), and would repeat it if necessary (30/30; 100%).

CONCLUSIONS

Esophageal capsule endoscopy is an adequate alternative diagnostic method for the study of gastroesophageal reflux disease and for the screening of esophageal varices in patients refusing to undergo conventional upper gastrointestinal endoscopy.
