A multicenter survey on endoscopic retrograde cholangiopancreatography during the COVID-19 pandemic in northern and central Italy.

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.

Endoscopic submucosal dissection: Italian national survey on current practices, training and outcomes.

BACKGROUND AND AIMS: Most of the evidence supporting endoscopic submucosal dissection (ESD) comes from Asia. European data are primarily reported by specialized referral centers and thus may not be representative of common European ESD practice. The aim of this study is to understand the current state of ESD practice across Italian endoscopy centers. METHODS: All Italian endoscopists who were known to perform ESD were invited to complete a structured questionnaire including: operator features and competencies, ESD training details and clinical outcomes over a 2-year period. RESULTS: Twenty-nine operators from 23 centers (69% response rate) completed the questionnaire: 18 (62%) were <50 years old; 7 (24%) were female; 16 (70%) were located in Northern Italy. Overall ESD volume was <40 cases in 9 (31%) operators, 40-80 in 8 (27.5%), 80-150 in 4 (13.8%) and >150 in 8 (27.5%). Colorectal ESD was predominant for operators with an experience >80 cases. En-bloc resection rates ranged from 77.2 to 97.2% depending on the anatomic location with an R0 resection rate range of 75.3-93.6%. ESD perforation rates in the colon and rectum were significantly lower when experience was >150 compared to 80-150 cases (p < 0.0001 and p = 0.006 for colon and rectum, respectively). CONCLUSION: ESD in Italy is performed by a significant number of operators. Overall, Italian endoscopists performing ESD have achieved a good competence level. However, there is much variability in training protocols, initial supervision of procedures, practice settings, case mix and procedural volume/year that are likely responsible for some of the suboptimal resectional outcomes and increased perforation risk, mainly in the colon. Standardized training programs, practice parameters and auditing of outcomes are required.

Temporary endoscopic metallic stent for idiopathic esophageal achalasia.

Idiopathic achalasia is a motor disorder of the esophagus of unknown etiology caused by loss of motor neurons determining an altered motility. It may determine severe symptoms such as progressive dysphagia, regurgitations, and pulmonary aspirations. Many therapeutic options may be offered to patients with achalasia, from surgery to endoscopic treatments such as pneumatic dilation, botulinum injection, peroral endoscopic myotomy, or endoscopic stenting. Recently, temporary placement of a stent was proposed by Cheng as therapy for achalasia disorders, whereas no Western authors have dealt with it up to date. The present study reports our preliminary experience in 7 patients with achalasia treated with a temporary stent. Partially covered self-expanding metallic stents (Micro-Tech, Nanjin, China) 80 mm long and 30 mm wide were placed under fluoroscopic control and removed after 6 days. Clinical follow-up was scheduled to check endoscopic success, symptoms release, and complications. The placement and the removal of the stents were obtained in all patients without complications. Mean clinical follow-up was 19 months. Five out of 7 patients referred total symptoms release and 2 experienced significant improvement of dysphagia. The procedure was not time consuming and was safe; no mild or severe complications were registered. In conclusion, our results may suggest a possible safe and effective endoscopic alternative treatment in patients with achalasia; however, further larger studies are necessary to confirm these promising, but very preliminary, data.

Enteroscope without overtube for cecal intubation after an incomplete colonoscopy.

BACKGROUND: Cecal intubation is one of the targets of colon endoscopic evaluation, however even under experienced hands 5-10% of colonoscopies are incomplete. AIMS: The aim of the study is to evaluate the usefulness of single balloon enteroscope (SBE) without employing overtube-balloon equipment in patients with incomplete colonoscopy. METHODS: Between January 2009 and July 2010, patients with an incomplete standard colonscopy were prospectively enrolled to perform a colonoscopy with a single balloon enteroscope. Examinations were performed by the same expert operator during the same session. RESULTS: Enteroscopy was performed on 79 patients, cecal intubation were obtained in 93.6% of the cases (74/79). It provided a new diagnosis in 43% of cases (34/79). Procedure was safe and well tolerated. Overall the additional use of single balloon enteroscope allowed to obtain the cecal intubation in up to 99.2% cases (898/905). CONCLUSIONS: The use of the enteroscope without overtube-balloon equipment may be an effective method to increase the cecal intubation rate after failure of a standard colonoscopy.

Endoscopic treatment of postgastrectomy duodenal fistula with an over-the-scope clip.

Bleeding peptic ulcer is a life threatening condition with high mortality rate but often treatable by endoscopy. Surgical indications in case of gastroduodenal ulcers are confined to endoscopic and radiological failures in bleeding control. Duodenal fistula (DF) is a rare complication of gastric resection and even if a rare event it may be a life threatening condition. Surgical and medical options could not solve the DF. Herein we report a case of an old patient underwent emergency gastrectomy for ulcer's bleeding who developed DF associated to sepsis, malnutrition and, hydro-electrolyte disorders not responding to surgical and medical attempts. We demonstrated, for the first time, the efficacy of over the scope clips (OTSC®) in the treatment of postoperative duodenal fistulas not responding to surgical and medical treatment in high risk patient.
