RÉSUMÉ
BACKGROUND AND STUDY AIM: The traditional endoscopic therapy of anastomotic strictures (AS) after orthotopic liver transplantation (OLT) is multiple ERCPs with the insertion of an increasing number of plastic stents side-by-side. Fully covered self-expanding metal stents (cSEMS) could be a valuable option to decrease the number of procedures needed or non-responders to plastic stents. This study aims to retrospectively analyse the results of AS endoscopic treatment by cSEMS and to identify any factors associated with its success. PATIENTS AND METHODS: Ninety-one patients (mean age 55.9 ± 7.6 SD; 73 males) from nine Italian transplantation centres, had a cSEMS positioned for post-OLT-AS between 2007 and 2017. Forty-nine (54%) patients were treated with cSEMS as a second-line treatment. RESULTS: All the procedures were successfully performed without immediate complications. After ERCP, adverse events occurred in 11% of cases (2 moderate pancreatitis and 8 cholangitis). In 49 patients (54%), cSEMSs migrated. After cSEMS removal, 46 patients (51%) needed further endoscopic (45 patients) or radiological (1 patient) treatments to solve the AS. Lastly, seven patients underwent surgery. Multivariable stepwise logistic regression showed that cSEMS migration was the only factor associated with further treatments (OR 2.6, 95% CI 1.0-6.6; p value 0.03); cSEMS implantation before 12 months from OLT was associated with stent migration (OR 5.2, 95% CI 1.7-16.0; p value 0.004). CONCLUSIONS: cSEMS appears to be a safe tool to treat AS. cSEMS migration is the main limitation to its routinary implantation and needs to be prevented, probably with the use of new generation anti-migration stents.

Familial adenomatous polyposis (FAP) is an autosomal-dominant hereditary condition associated with germline mutations in the adenomatous polyposis coli gene. Patient management involves prophylactic surgery and intensive life-long endoscopic surveillance. Diet is a major concern for patients with FAP, who are generally free of symptoms before surgery but tend to have issues related to bowel function postoperatively. We hypothesized that a low-inflammatory diet based on the principles and recipes of the Mediterranean diet would reduce markers of local and systemic inflammation. Twenty-eight patients with FAP over 18 years of age who underwent rectum-sparing prophylactic colectomy and were included in our surveillance program participated in a pilot dietary intervention study. Blood and stool samples at baseline (T0), at the end of the dietary intervention (T1, three months), and at the end of the study (T2, six months after T0) were collected. Gastrointestinal inflammation markers including fecal calprotectin, cyclooxygenase-2, and 15-hydroxyprostaglandin dehydrogenase were evaluated. Serum calprotectin, insulin, insulin-like growth factor-1, C-reactive protein, and glycated hemoglobin were also assessed. Significant changes in serum calprotectin, insulin, and insulin-like growth factor-1 levels occurred over time. Borderline significant changes were observed in the neutrophil-lymphocyte ratio. These changes were noticeable immediately at the end of the 3-month active dietary intervention (T1). A significant increase in 15-hydroxyprostaglandin dehydrogenase expression in the normal crypts of matched samples was also observed between T0 and T2. This pilot study supports the hypothesis that a low-inflammatory diet can modulate gastrointestinal markers of inflammation in individuals with FAP. PREVENTION RELEVANCE: Cancer is known to be related to inflammatory conditions. This study suggests that anti-inflammatory dietary intervention may potentially prevent adenomas and cancer in FAP patients by reducing systemic and tissue inflammatory indices.

INTRODUCTION: Endobronchial ultrasound (EBUS) is an endoscopic diagnostic procedure combining flexible fibrobronchoscopy with ultrasound techniques; it allows transbronchial needle aspiration biopsy for the diagnosis and staging of mediastinal masses. We present our preliminary experience with the use of the i-gel O2 supraglottic airway device for management of EBUS procedures. METHODS: An observational study on 39 patients who underwent EBUS under general anesthesia was performed. Airways were managed with i-gel O2 by anesthesiologists unfamiliar with it. Data collected included patient characteristics, i-gel O2 positioning, mechanical ventilation, procedure, and complications occurring during and after the EBUS. RESULTS: The i-gel airway was successfully positioned during the first attempt in 34/39 cases (87.2%). No failed positioning was recorded. The EBUS scope easily passed through the i-gel in all patients and in 14 (35.6%) cases it was also inserted through the esophagus allowing the examination or fine needle aspiration of paraesophageal lymph nodes. In one case, during the EBUS procedure, the i-gel was dislocated but easily put in place again. During EBUS, air leakages were significant in 2 cases (5.1%) and minimal in 14 cases (35.9%). A brief self-solved laryngospasm and a bronchospasm during bronchoscopy were recorded. After recovery, no patients had dysphagia; mild odynophagia and pharyngodinia were referred by 2 (5.1%) and 12 (30.1%) patients, respectively. CONCLUSIONS: The i-gel O2 airway is easy to position and manage even for anesthesiologists unfamiliar with it. This supraglottic airway device is suitable for a complete endosonographic evaluation of the mediastinum.

GOALS: The present survey from the Italian Society of Digestive Endoscopy (SIED-Società Italiana di Endoscopia Digestiva) was aimed at reporting infection control practice and outcomes at Digestive Endoscopy Units in a high-incidence area. BACKGROUND: Lombardy was the Italian region with the highest coronavirus disease-2019 (COVID-19) prevalence, at the end of March 2020 accounting for 20% of all worldwide deaths. Joint Gastro-Intestinal societies released recommendations for Endoscopy Units to reduce the risk of the contagion. However, there are few data from high-prevalence areas on adherence to these recommendations and on their efficacy. METHODS: A survey was designed by the Lombardy section of SIED to analyze (a) changes in activity and organization, (b) adherence to recommendations, (c) rate of health care professionals' (HCP) infection during the COVID-19 outbreak. RESULTS: In total, 35/61 invited centers (57.4%) participated; most modified activities were according to recommendations and had filtering face piece 2/filtering face piece 3 and water-repellent gowns available, but few had negative-pressure rooms or provided telephonic follow-up; 15% of HCPs called in sick and 6% had confirmed COVID-19. There was a trend (P=0.07) toward different confirmed COVID-19 rates among endoscopists (7.9%), nurses (6.6%), intermediate-care technicians (3.4%), and administrative personnel (2.2%). There was no correlation between the rate of sick HCPs and COVID-19 incidence in the provinces and personal protective equipment availability and use, whereas an inverse correlation with hospital volume was found. CONCLUSIONS: Adherence to recommendations was rather good, though a minority were able to follow all recommendations. Confirmed COVID-19 seemed higher among endoscopists and nurses, suggesting that activities in the endoscopy rooms are at considerable viral spread risk.

After the lockdown during the emergency phase of the Covid-19 pandemic, we have to deal with phase 2, a period of uncertain duration, with a controlled and progressive return to normalization, in which we need to reconcile our work and our movements with the presence of the virus on our territory. Digestive endoscopic activity is a high-risk transmission procedure for Covid-19. The measures put in place to protect healthcare personnel and patients are stressful and "time-consuming" and lead to a reduction in the number of endoscopic procedures that can be performed. In this scenario, the Oncological Institutes are forced to make a rigorous selection of patients to undergo endoscopic examinations and treatments, according to lists of exceptional priorities, in order to guarantee cancer patients and subjects at high risk of developing digestive tumors, a preferential diagnostic and therapeutic process, protected from contagion risks. For this purpose, cuts and postponing times of endoscopic performances are here proposed, which go beyond the guidelines of scientific societies and have little evidences in the literature. These changes should be applied limited to this exceptional period and in proportion to the capacity of each operating unit in order to meet the demands of the patients.

Colorectal cancer (CRC) screening programs help diagnose cancer precursors and early cancers and help reduce CRC mortality. However, currently recommended tests, the fecal immunochemical test (FIT) and colonoscopy, have low uptake. There is therefore a pressing need for screening strategies that are minimally invasive and consequently more acceptable to patients, most likely blood based, to increase early CRC identification. MicroRNAs (miRNAs) released from cancer cells are detectable in plasma in a remarkably stable form, making them ideal cancer biomarkers. Using plasma samples from FIT-positive (FIT+) subjects in an Italian CRC screening program, we aimed to identify plasma circulating miRNAs that detect early CRC. miRNAs were initially investigated by quantitative real-time PCR in plasma from 60 FIT+ subjects undergoing colonoscopy at Fondazione IRCCS Istituto Nazionale dei Tumori, then tested on an internal validation cohort (IVC, 201 cases) and finally in a large multicenter prospective series (external validation cohort [EVC], 1121 cases). For each endoscopic lesion (low-grade adenoma [LgA], high-grade adenoma [HgA], cancer lesion [CL]), specific signatures were identified in the IVC and confirmed on the EVC. A two-miRNA-based signature for CL and six-miRNA signatures for LgA and HgA were selected. In a multivariate analysis including sex and age at blood collection, the areas under the receiver operating characteristic curve (95% confidence interval) of the signatures were 0.644 (0.607-0.682), 0.670 (0.626-0.714) and 0.682 (0.580-0.785) for LgA, HgA and CL, respectively. A miRNA-based test could be introduced into the FIT+ workflow of CRC screening programs so as to schedule colonoscopies only for subjects likely to benefit most.

Patients with familial adenomatous polyposis (FAP) depend on a lifelong endoscopic surveillance programme and prophylactic surgery, and usually suffer nutritional problems. Intestinal inflammation has been linked to both FAP and colorectal cancer. Epidemiological studies show a relationship between diet and inflammation. Preventive dietary recommendations for FAP patients are so far lacking. We have designed a nonrandomized prospective pilot study on FAP patients to assess whether a low-inflammatory diet based on the Mediterranean diet principles and recipes, by interacting with the microbiota, reduces gastrointestinal markers of inflammation and improves quality of life. This report describes the scientific protocol of the study and reports the participants' adherence to the proposed dietary recommendations. Thirty-four FAP patients older than 18 years, bearing the APC pathogenic variant, who underwent prophylactic total colectomy with ileo-rectal anastomosis were eligible into the study. During the 3-month dietary intervention, they reported improvements in their consumption of Mediterranean foods (vegetables, fruits, fish, and legumes), and a reduction in pro-inflammatory foods (red/processed meat and sweets); this led to a significant increase in their adherence to the Mediterranean diet. The improvement was accompanied by a decrease in the number of diarrhoeal discharges. These preliminary results are encouraging with regard to feasibility, dietary outcome measures, and safety.

BACKGROUND AND OBJECTIVE: A new 20-gauge (G) biopsy needle with a core-trap technology has been developed with a large core size and enhanced flexibility. The aim of this multicenter study was to determine the feasibility, efficacy, and safety of EUS-guided fine-needle biopsy (EUS-FNB) with the new 20G needle in diagnosing subepithelial lesions (SELs). MATERIALS AND METHODS: Retrospectively collected data from consecutive patients with SELs undergoing EUS-FNB with the 20G needle at five centers were analyzed. RESULTS: A total of 50 SELs were included. The mean lesion size was 43.1 ± 17.5 mm. The lesion locations were esophagus (n = 1), stomach (n = 37), distal duodenum (n = 5), rectum (n = 6), and colon (n = 1). The procedure was technically feasible in all patients. Definitive diagnosis with full histological assessment including immunohistochemistry was obtained in 88% (44/50) of the patients. Considering malignant versus benign lesions, the sensitivity, specificity, positive predictive value, and negative predictive value were 85% (95% confidence interval [CI] 70.2-94.3), 100% (95% CI 58.7%-100%), 100% (95% CI 85.1%-100%), and 62.5 (95% CI 27.7-84.8), respectively. No major complications requiring additional care have been observed. CONCLUSIONS: In this multicenter study, we found that EUS-FNB with the new 20G core needle is an effective and safe method for the diagnosis of SELs with a high rate of producing adequate histological material and high diagnostic accuracy even from difficult-to-approach anatomical locations.
RÉSUMÉ
BACKGROUND: The most appropriate endo-therapeutic approach to biliary anastomotic strictures is yet to be defined. AIM: To retrospectively report on the endo-therapy of duct-to-duct anastomotic strictures during 2013 in Italy. METHODS: Data were collected from 16 Endoscopy Units at the Italian Liver Transplantation Centers (BASALT study group). RESULTS: Complete endo-therapy and follow-up data are available for 181 patients: 101 treated with plastic multistenting, 26 with fully covered self-expandable metal stenting and 54 with single stenting. Radiological success was achieved for 145 patients (80%), that is, 88% of plastic multistenting, 88% of self-expandable metal stenting and 61% of single stenting (P < 0.001 vs plastic multistenting; P < 0.05 vs self-expandable metal stenting). After first-line endo-therapy failure, the patients underwent a second-line endo-therapy with plastic multistenting for 25%, fully covered self-expandable metal stenting for 53% and single stenting for 22% of cases, and radiological success was achieved for 84%, that is, 100%, 85% and 63% with plastic multistenting, self-expandable metal stenting and single stenting (P < 0.05 vs plastic multistenting or self-expandable metal stenting) respectively. Procedure-related complications occurred in 7.8% of endoscopic retrograde cholangiopancreatographies. Overall, clinical success was achieved in 87% of patients after a median follow-up of 25 months. CONCLUSION: Plastic multistenting is confirmed as the preferred first-line treatment, while fully covered self-expandable metal stenting as rescue option for biliary anastomotic strictures. Single stenting has sub-optimal results and should be abandoned.

BACKGROUND: Hemospray is a new endoscopic haemostatic powder that can be used in the management of upper gastrointestinal bleedings. AIMS: To assess the efficacy and safety of Hemospray as monotherapy for the treatment of acute upper gastrointestinal bleeding due to cancer. METHODS: The endoscopy databases of 3 Italian Endoscopic Units were reviewed retrospectively and 15 patients (8 males; mean age 74 years) were included in this study. RESULTS: Immediate haemostasis was achieved in 93% of cases. Among the successful cases, 3 re-bled, one case treated with Hemospray and injection had a good outcome, while 2 cases died both re-treated with Hemospray, injection and thermal therapy. No complications related to Hemospray occurred. Finally, 80% of patients had a good clinical outcome at 30days and 50% at six months. CONCLUSION: Hemospray may be considered an effective and safe method for the endoscopic management of acute neoplastic upper gastrointestinal bleedings.

AIM: To determine the outcome of the management of iatrogenic gastrointestinal tract perforations treated by over-the-scope clip (OTSC) placement. METHODS: We retrospectively enrolled 20 patients (13 female and 7 male; mean age: 70.6 ± 9.8 years) in eight high-volume tertiary referral centers with upper or lower iatrogenic gastrointestinal tract perforation treated by OTSC placement. Gastrointestinal tract perforation could be with oval-shape or with round-shape. Oval-shape perforations were closed by OTSC only by suction and the round-shape by the "twin-grasper" plus suction. RESULTS: Main perforation diameter was 10.1 ± 4.3 mm (range 3-18 mm). The technical success rate was 100% (20/20 patients) and the clinical success rate was 90% (18/20 patients). Two patients (10%) who did not have complete sealing of the defect underwent surgery. Based upon our observations we propose two types of perforation: Round-shape "type-1 perforation" and oval-shape "type-2 perforation". Eight (40%) out of the 20 patients had a type-1 perforation and 12 patients a type-2 (60%). CONCLUSION: OTSC placement should be attempted after perforation occurring during diagnostic or therapeutic endoscopy. A failed closure attempt does not impair subsequent surgical treatment.

AIM: To investigate gastrointestinal complications associated with non-steroidal anti-inflammatory drug (NSAIDs) use in children. METHODS: A retrospective, multicenter study was conducted between January 2005 and January 2013, with the participation of 8 Italian pediatric gastroenterology centers. We collected all the cases of patients who refer to emergency room for suspected gastrointestinal bleeding following NSAIDs consumption, and underwent endoscopic evaluation. Previous medical history, associated risk factors, symptoms and signs at presentation, diagnostic procedures, severity of bleeding and management of gastrointestinal bleeding were collected. In addition, data regarding type of drug used, indication, dose, duration of treatment and prescriber (physician or self-medication) were examined. RESULTS: Fifty-one patients, including 34 males, were enrolled (median age: 7.8 years). Ibuprofen was the most used NSAID [35/51 patients (68.6%)]. Pain was the most frequent indication for NSAIDs use [29/51 patients (56.9%)]. Seven patients had positive family history of Helicobacter pylori (H. pylori) infection or peptic ulcer, and 12 had associated comorbidities. Twenty-four (47%) out of 51 patients used medication inappropriately. Hematemesis was the most frequent symptom (33.3%). Upper gastrointestinal endoscopy revealed gastric lesions in 32/51 (62%) patients, duodenal lesions in 17 (33%) and esophageal lesions in 8 (15%). In 10/51 (19.6%) patients, a diagnosis of H. pylori gastritis was made. Forty-eight (94%) patients underwent medical therapy, with spontaneous bleeding resolution, while in 3/51 (6%) patients, an endoscopic hemostasis was needed. CONCLUSION: The data collected in this study confirms that adverse events with the involvement of the gastrointestinal tract secondary to NSAID use are also common in children.

BACKGROUND: The guidewire biliary cannulation (GWC) technique may increase the cannulation rate and decrease the risk for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. The aim of our multicenter prospective randomized controlled trial was to determine if the use of an atraumatic loop-tip guidewire reduces the rate of post-ERCP pancreatitis (PEP) compared with the standard contrast-assisted cannulation (CC) technique. METHODS: From June 2012 to December 2013, a total of 320 patients who had a naïve papilla and were referred for ERCP were randomly assigned to the GWC group (nâ=â160) or the CC group (nâ=â160). GWC or CC was randomly used. In cases of failed cannulation in both arms after crossover, biliary access was attempted with alternative techniques (e.âg., dual-wire technique, pancreatic duct stenting, precut). RESULTS: The biliary cannulation rates were 81â% in the GWC group and 73â% in the CC group (Pâ=ân.âs.). Following crossover, cannulation was successful in 8â% and 11â% of patients in the GWC and CC groups, respectively. With use of an alternative technique, the cannulation rates were 98â% in the GWC group and 96â% in the CC group, respectively. The rates of PEP were 5â% in the GWC group and 12â% in the CC group (Pâ=â0.027). The post-interventional complication rates did not differ between the two groups. CONCLUSION: GWC with the new wire guide is associated with a lower rate of PEP in comparison with the CC technique. Clinical trial reference number: NCT01771419.

BACKGROUND: Chronic constipation is a risk factor of inadequate bowel preparation for colonoscopy; however, no large clinical trials have been performed in this subgroup of patients. AIMS: To compare bowel cleansing efficacy, tolerability and acceptability of 2-L polyethylene-glycol-citrate-simethicone (PEG-CS) plus 2-day bisacodyl (reinforced regimen) vs. 4-L PEG in patients with chronic constipation undergoing colonoscopy. METHODS: Randomized, observer-blind, parallel group study. Adult outpatients undergoing colonoscopy were randomly allocated to 2-L PEG-CS/bisacodyl or 4-L PEG, taken as split regimens before colonoscopy. Quality of bowel preparation was assessed by the Ottawa Bowel Cleansing Scale (OBCS). The amount of foam/bubble interfering with colonic visualization was also measured. RESULTS: 400 patients were enrolled. There was no significant difference in successful cleansing (OBCS score ≤6): 80.2% in the 2-L PEG-CS/bisacodyl vs. 81.4% in the 4-L PEG group. Significantly more patients taking 2L PEG-CS/bisacodyl showed no or minimal foam/bubbles in all colonic segments (80% vs. 63%; p<0.001). 2-L PEG-CS/bisacodyl was significantly more acceptable for ease of administration (p<0.001), willingness to repeat (p<0.001) and showed better compliance (p=0.002). CONCLUSION: Split 2-L PEG-CS plus bisacodyl was not superior to split 4-L PEG for colonoscopy bowel cleansing in patients with chronic constipation; however, it performed better than the standard regimen in terms of colonic mucosa visualization, patient acceptance and compliance.

INTRODUCTION AND OBJECTIVES: Acute gastrointestinal (GI) bleeding can lead from mild to immediately life-threatening clinical conditions. Upper GI bleeding (UGIB) is associated with a mortality of 6-10%. Spurting and oozing bleeding are associated with major risk of failure. Hemospray™ (TC-325), a new hemostatic powder, may be useful in these cases. Aim of this study is to review the efficacy of traditional endoscopic treatment in Forrest 1a-1b ulcers and to investigate the usefulness of Hemospray in these patients. PATIENTS AND METHODS: A MEDLINE search was performed and articles that evaluated hemostatic efficacy and rebleeding rate with traditional endoscopic techniques related to Forrest classification were reviewed. Patients with Forrest 1a-1b ulcers were treated with Hemospray, either as monotherapy or in association with other endoscopic techniques. Primary outcome was immediate hemostasis, secondary outcomes were recurrent bleeding and adverse events related to Hemospray use. RESULTS: Analysis of literature showed that mean initial hemostasis success rate in Forrest 1a-1b ulcers was of 92.8%, and mean rebleeding rate was of 13.3%. We enrolled 13 patients treated with Hemospray. Initial hemostasis was achieved in 100% and we reported three cases of rebleeding. No adverse events occurred. CONCLUSION: Forrest 1a-1b bleeding ulcer is very difficult to treat. Hemospray appears to be an effective hemostatic therapy for these ulcers. However, additional prospective studies are needed to validate these findings.
