Heliosphere® BAG enables modest short-term weight loss with little side effects, although mid/long-term follow-up may entail partial weight gain. We believe it can be considered a useful bridge treatment in bariatric surgery in order to reduce chances of preoperative risks.

Background and study aims COVID-19 has dramatically impacted endoscopy practice because upper endoscopy procedures can be aerosol-generating. Most elective procedures have been rescheduled. Endoscopic retrograde cholangiopancreatography (ERCP) is frequently performed in emergency or urgent settings in which rescheduling is not possible. We evaluated the impact of the COVID-19 pandemic on ERCP in Italy during the SARS-CoV-2 lockdown, in areas with high incidence of COVID-19. Patients and methods We performed a retrospective survey of centers performing ERCP in high COVID-19 prevalence areas in Italy to collect information regarding clinical data from patients undergoing ERCP, staff, case-volume and organization of endoscopy units from March 8, 2020 to April 30, 2020. Results We collected data from 31 centers and 804 patients. All centers adopted a triage and/or screening protocol for SARS-CoV-2 and performed follow-up of patients 2 weeks after the procedure. ERCP case-volume was reduced by 44.1 % compared to the respective 2019 timeframe. Of the 804 patients undergoing ERCP, 22 (2.7 %) were positive for COVID-19. Adverse events occurred at a similar rate to previously published data. Of the patients, endoscopists, and nurses, 1.6 %, 11.7 %, and 4.9 %, respectively, tested positive for SARS-CoV-2 at follow up. Only 38.7 % of centers had access to a negative-pressure room for ERCP. Conclusion The case-volume reduction for ERCP during lockdown was lower than for other gastrointestinal endoscopy procedures. No definitive conclusions can be drawn about the percentage of SARS-CoV-2-positive patients and healthcare workers observed after ERCP. Appropriate triage and screening of patients and adherence to society recommendations are paramount.

Background & Aim: Standard 10-day sequential therapy is advised as first-line therapy for Helicobacter pylori (H. pylori) eradication by current Italian guidelines. Some data suggested that a 14-day regimen may achieve higher eradication rates. This study compared the efficacy of sequential therapy administered for either 10- or 14-days.Methods: This prospective, multicenter, open-label study enrolled patients with H. pylori infection without previous treatment. Patients were receiving a sequential therapy for either 10 or 14 days with esomeprazole 40 mg and amoxicillin 1 g (5 or 7 days) followed by esomeprazole 40 mg, clarithromycin 500 mg and tinidazole 500 mg (5 or 7 days), all given twice daily. Bacterial eradication was checked using 13C-urea breath test. Eradication cure rates were calculated at both Intention-to-treat (ITT) and per-protocol (PP) analyses.Results: A total of 291 patients were enrolled, including 146 patients in 10-day and 145 in the 14-day regimen. The eradication rates were 87% (95% CI = 81.5-92.4) and 90.3% (95% CI = 85.5-95.1) at ITT analysis with the 10- and 14-day regimen, respectively, and 92.7% (95% CI = 88.3-97) and 97% (95% CI = 94.2-99.9) at PP analysis (p =0.37). Among patients, who earlier had interrupted therapy, bacterial eradication was achieved in 8 out of 9 who completed the first therapy phase and performed at least ≥3 days of triple therapy in the second phase.Conclusion: This study found that both 10- and 14-day sequential therapies achieved a high eradication rate for first-line H. pylori therapy in clinical practice.

LETTERS TO THE EDITOR Myasthenia gravis in a patient with chronic active hepatitis C during interferon-a treatment Batocchi et all recently reported the occurrence of autoimmune myasthenia gravis during interferon-a (INF-a) treatment in two patients with malignancies. We report a patient who developed myasthenia gravis after INF-a treatment for chronic hepatitis C. A previously healthy 54 year old man developed malaise and dyspepsia three years ago. Increased serum concentrations of alanine aminotransferase and aspartate aminotransferase led to a serological diagnosis of hepatitis C infection. Liver biopsy showed a histological picture of chronic active hepatitis. Two years later, in March 1993, the patient received INF-a-nl (Wellferon, Wellcome, UK) subcutaneously at a dose of 9 x 106 U on alternate days. After nine
