U p to 20% of health care personnel (HCP) were found to be infected with coronavirus disease (COVID-19) 1 in the outbreak in northern Italy. 2 Recommendations on patient and HCP protection have been made, such as postponing procedures, triage, use of personal protective equipment (PPE), and creation of differentiated in-hospital pathways. 3,4 However, several barriers against the adoption of these strategies exist, including cultural factors and shortages of medical resources; therefore, there are few reports of real-world experiences and outcomes with their adoption. 5 The aim of this survey was to investigate the burden of COVID-19 on endoscopic activity in a high-risk area of COVID-19 outbreak, approaches to evaluating patients, adoption and compliance of HCP with protective measures, and initial possible viral transmission outcomes from endoscopy units within a large, community-based setting (both between patients and HCP and between HCP). MethodsThe study was conducted as a survey between March 16 and March 21, 2020. Directors of emergency departments in highrisk areas of northern Italy (Supplementary Figure 1) were invited by e-mail to complete a questionnaire (Figure 1 and Supplementary Table 1). Participation was voluntary. Additional methodology is provided in the Supplementary Material. Results Characteristics of the Endoscopy UnitsA total of 42 endoscopy units were invited, of which 41 participated (97.6%). Most respondents (n ¼ 37, 90.2%) were from high-volume endoscopy units, for a total of 968 endoscopy personnel, including 323 endoscopists, 496 nurses, and 149 health care assistants. Changes in Endoscopy Activity Related to Coronavirus Disease 2019All endoscopy units had patients diagnosed with COVID-19 in their hospital. All but 1 center (40/41, 97.6%) reduced Infection Prevention and Control Measures for Coronavirus Disease 2019Regarding the preventive measures taken after the first Italian case (February 18, 2020), 5 (12.2%) endoscopy units did not take any measures, 29 (70.7%) endoscopy units adopted a triage for risk stratification of COVID-19 infection, 7 (17.1%) endoscopy units decreased endoscopic See editorial on page 36.

The incidence of AC in BE is low, confirming recent data from the literature reporting an overestimation of cancer risk in these patients. In our patient cohort, surveillance involved a large expenditure of effort but did not prevent any cancer deaths. The benefit of surveillance remains uncertain.

Background and Aims: A recent electron microscopy study suggested that dilated intercellular spaces (DIS) are specific for acid reflux-damaged esophageal epithelium. Electron microscopy is, however, expensive and difficult to apply to routine biopsies. The aims of this study are to establish a method for assessing DIS on light microscopy of esophageal biopsies and to estimate its association with current clinicopathological parameters of esophagitis. Materials and Methods: 21 patients with reflux symptoms were investigated. Light microscopy biopsies were assessed for DIS size by a semiquantitative method and computer-assisted, static morphometry. A DIS score accounting for DIS size and distribution was assigned to each patient and its association with 30 clinicopathological variables investigated by univariate and multivariate logistic regression. Results: Both the semiquantitative method and static morphometry identified 4 different classes of DIS size. The DIS score was significantly and independently associated with the esophageal symptoms score, the histological score of esophagitis and the relevant morphometry data. Conclusions: DIS may be efficiently assessed during light microscopy of routine esophageal biopsies. Since correlation with both the histology and the symptoms of esophagitis, the DIS score may be considered a novel parameter of esophagitis and is suggested for the routine evaluation of esophageal biopsies in patients with reflux disease.

Barrett’s oesophagus (BO) is the primary precursor lesion for oesophageal adenocarcinoma (ADC). The natural history of metaplasia-dysplasia-carcinoma sequence remains largely unknown. HER2/neu oncogene results overexpressed/amplified in preneoplastic lesions and in ADC of the oesophagus and it has been associated with poor prognosis. Our aim was to evaluate the role of HER2 overexpression/amplification in predicting the conversion from precursor lesions to ADC. We retrospectively evaluated by univariate analysis of single variables clinical records and histological specimens of 21 patients with a confirmed diagnosis of BO and/or oesophageal dysplasia. Clinical variables included age, gender, alcohol and smoking intake, presence of symptoms (pyrosis, disphagia) and endoscopic features (length). HER2 status was studied by immunohistochemistry and fluorescence in situ hybridization (FISH) on paraffin-embedded tissue. The end-points were the occurrence of progression and the time-to-progression (TTP) from the initial histologic lesion to the worst pathological pattern. Median age at diagnosis was 63 years (range 37–84). BO median length was 4.5 cm. Progression occurred in 11 of 21 patients and median TTP was 24 months. HER2 was overexpressed/amplified in 8 of 21 (38%) patients. HER2 overexpression/ amplification and the presence of dysplasia were statistically associated with progression (P= 0.038). This study provides evidence for a possible role of HER2 in the transition from dysplasia to ADC of the oesophagus. This fact could help in identifying patients at high risk of malignant transformation.

Background:The SARS-CoV-2 pandemic has had a huge impact on healthcare systems, resulting in many routine diagnostic procedures either being halted or postponed. Aims: To evaluate whether the diagnoses of colorectal, gastric and pancreatic cancers have been impacted by the SARS-CoV-2 pandemic in Italy. Methods: A survey designed to collect the number of histologically-proven diagnoses of the three cancers in gastroenterology services across Italy from January 1 to October 31 in 2017-2020. Non-parametric ANOVA for repeated measurements was applied to compare distributions by years and macro-areas. Results: Compared to 2019, in 2020 gastric cancer diagnoses decreased by 15.9%, CRC by 11.9% and pancreatic by 9.9%. CRC distributions showed significant differences between all years, stomach cancer be-
