Objectives: This study aimed to evaluate trends in hospitalizations and outcomes of acute pancreatitis (AP) according to first admitting hospital unit and hospital volumes., Methods: Hospital discharge records of patients with AP admitted in the Veneto Region (Northeast Italy) during the period 2001-2015 were examined., Results: A total of 23,389 patients (54% males; mean age, 62.2 years; standard deviation, 19.3 years) were admitted for AP. Both hospitalization (32.4 to 29.5/100,000 inhabitants per year; P < 0.05) and in-hospital mortality (1.41 to 0.79/100,000 inhabitants per year; P < 0.05) decreased over the study period. Case fatality rate was altogether 3.2%. The percentages of patients admitted in surgery, nongastroenterology medical units, gastroenterology, and intensive care were 52%, 30%, 16%, and 2%, respectively. Fewer fatalities were observed in gastroenterology units (1.7%) compared with nongastroenterology medical units (4.3%; odds ratio, 0.37; 95% confidence interval, 0.28-0.49) and surgical units (2.7%; odds ratio, 0.61; 95% confidence interval, 0.47-0.80). Fatalities decreased progressively with increasing hospital volumes from 3.7% to 2.9% (P < 0.05)., Conclusion: In the Veneto Region, both hospitalizations and in-hospital mortality for AP significantly decreased over the last 15 years. Case fatality rate was lowest for patients admitted in gastroenterology units.

Objective: To establish the incidence and risk factors for progression to high-grade intraepithelial neoplasia (HG-IEN) or Barrett's esophageal adenocarcinoma (BAc) in a prospective cohort of patients with esophageal intestinal metaplasia [(BE)]., Background: BE is associated with an increased risk of BAc unless cases are detected early by surveillance. No consistent data are available on the prevalence of BE-related cancer, the ideal surveillance schedule, or the risk factors for cancer., Methods: In 2003, a regional registry of BE patients was created in north-east Italy, establishing the related diagnostic criteria (endoscopic landmarks, biopsy protocol, histological classification) and timing of follow-up (tailored to histology) and recording patient outcomes. Thirteen centers were involved and audited yearly. The probability of progression to HG-IEN/BAc was calculated using the Kaplan-Meier method; the Cox regression model was used to calculate the risk of progression., Results: HG-IEN (10 cases) and EAc (7 cases) detected at the index endoscopy or in the first year of follow-up were considered to be cases of preexisting disease and excluded; 841 patients with at least 2 endoscopies {median, 3 [interquartile range (IQR): 2-4); median follow-up = 44.6 [IQR: 24.7-60.5] months; total 3083 patient-years} formed the study group [male/female = 646/195; median age, 60 (IQR: 51-68) years]. Twenty-two patients progressed to HG-IEN or BAc (incidence: 0.72 per 100 patient-years) after a median of 40.2 (26.9-50.4) months. At multivariate analysis, endoscopic abnormalities, that is, ulceration or nodularity (P = 0.0002; relative risk [RR] = 7.6; 95% confidence interval, 2.63-21.9), LG-IEN (P = 0.02, RR = 3.7; 95% confidence interval, 1.22-11.43), and BE length (P = 0.01; RR = 1.16; 95% confidence interval, 1.03-1.30) were associated with BE progression. Among the LG-IEN patients, the incidence of HG-IEN/EAc was 3.17 patient-years, that is, 6 times higher than in BE patients without LG-IEN., Conclusions: These results suggest that in the absence of intraepithelial neoplastic changes, BE carries a low risk of progression to HG-IEN/BAc, and strict surveillance (or ablative therapy) is advisable in cases with endoscopic abnormalities, LG-IEN or long BE segments.
