RESUMO
BACKGROUND AND AIM: In surgically altered anatomy (SAA), endoscopic retrograde cholangiopancreatography (ERCP) can be challenging, and it remains debatable the choice of the optimal endoscopic approach within this context. We aim to show our experience and evaluate the technical and clinical success of endoscopic treatment performed in the setting of adverse events (AE) after pancreaticoduodenectomy (PD). METHODS: This study was conducted on a retrospective cohort of patients presenting biliopancreatic complications after PD from 01/01/2012 to 31/12/2022. All patients underwent ERCP at our Endoscopy Unit. Clinical, instrumental data, and characteristics of endoscopic treatments were collected. RESULTS: 133 patients were included (80 M, mean age = 65 y.o.) with a total of 296 endoscopic procedures (median = 2 procedures/treatment). The indications for ERCP were mainly biliary AE (76 cases, 57.1%). Technical success was obtained in 121 patients of 133 (90.9%). 112 out of 133 (84.2%) obtained clinical success. Nine patients out of 112 (8%) experienced AEs. Clinical success rates were statistically different between patients with biliary or pancreatic disease (93.4% vs 73.6%, p < 0.0001). Septic patients were 38 (28.6%) and showed a worse prognosis than non-septic ones (clinical success: 65.7% vs 91.5%, p = 0.0001). During follow-up, 9 patients (8%), experienced recurrence of the index biliopancreatic disease with a median onset at 20 months (IQR 6-40.1). CONCLUSION: Our case series demonstrated that the use of a pediatric colonoscope in ERCP procedures for patients with AEs after PD is both safe and effective in treating the condition, even in a long-term follow-up.
RESUMO
OBJECTIVES: Endoscopic retrograde cholangiopancreatography (ERCP) represents the gold standard for jaundice palliation in patients with distal malignant biliary obstruction (DMBO). Biliary drainage using electrocautery lumen apposing metal stent (EC-LAMS) is currently a well-established procedure when ERCP fails. In a palliative setting the endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) could represent an easy and valid option. We performed a prospective study with a new EC-LAMS with the primary aim to assess the clinical success rate of EUS-GBD as a first-line approach to the palliation of DMBO. METHODS: In all, 37 consecutive patients undergoing EUS-GBD with a new EC-LAMS were prospectively enrolled. Clinical success was defined as bilirubin level decrease >15% within 24 h and >50% within 14 days after EC-LAMS placement. RESULTS: The mean age was 73.5 ± 10.8 years; there were 17 male patients (45.9%). EC-LAMS placement was technically feasible in all patients (100%) and the clinical success rate was 100%. Four patients (10.8%) experienced adverse events, one bleeding, one food impaction, and two cystic duct obstructions because of disease progression. No stent-related deaths were observed. The mean hospitalization was 7.7 ± 3.4 days. Median overall survival was 4 months (95% confidence interval 1-8). CONCLUSION: Endoscopic ultrasound-guided gallbladder drainage with the new EC-LAMS is a valid option in palliative endoscopic biliary drainage as a first-step approach in low survival patients with malignant jaundice unfit for surgery. A smaller diameter EC-LAMS should be preferred, particularly if the drainage is performed through the stomach, to avoid potential food impaction, which could result in stent dysfunction.

BACKGROUND AND AIMS: The optimal endoscopic resection method of challenging colorectal lesions (ie, adenomatous recurrences, nongranular laterally spreading tumors [LST-NGs], lesions without lifting sign <30 mm) is still under debate. The aim of this study was to directly compare endoscopic submucosal dissection (ESD) and endoscopic full-thickness resection (EFTR) for the resection of challenging colorectal lesions in a randomized trial. METHODS: A multicenter, prospective, randomized study was performed in 4 Italian referral centers. Consecutive patients referred for endoscopic resection of challenging lesions were randomly assigned to undergo EFTR or ESD. Primary outcomes were complete (R0) resection and en bloc resection of lesions. Technical success, procedure time, procedure speed, area of the resected specimen, adverse event rate, and local recurrence rate at 6 months were also compared. RESULTS: Overall, 90 patients were included in the study, equally representing the 3 challenging lesion types. Age and sex were comparable in the 2 groups. En bloc resection was obtained in 95.5% of the EFTR group and in 93.3% of the ESD group. R0 resection rate was comparable in the 2 groups (EFTR vs ESD, 42 [93.3%] vs 36 [80%]; P = .06). The EFTR group exhibited a significantly shorter total procedure time (25.6 ± 10.6 minutes vs 76.7 ± 26.4 minutes, P ≤ .01), as well as overall procedure speed (16.8 ± 11.8 mm2/min vs 11.9 ± 9.2 mm2/min, P = .03). The EFTR group had a significantly smaller mean lesion size (21.6 ± 8.3 mm vs 28.7 ± 7.7 mm, P ≤ .01). Adverse events were reported less frequently in patients in the EFTR group (4.44% vs 15.5%, P = .04). CONCLUSIONS: EFTR is comparable to ESD in the treatment of challenging colorectal lesions in terms of safety and efficacy. EFTR is considerably faster than ESD in the treatment of nonlifting lesions and adenoma recurrences. (Clinical trial registration number: NCT05502276.).

PURPOSE: Garlic consumption has been inversely associated to intestinal adenoma (IA) and colorectal cancer (CRC) risk, although evidence is not consistent. Gut microbiota has been implied in CRC pathogenesis and is also influenced by garlic consumption. We analyzed whether dietary garlic influence CRC risk and bacterial DNA in blood. METHODS: We conducted a case-control study in Italy involving 100 incident CRC cases, 100 IA and 100 healthy controls matched by center, sex and age. We used a validated food frequency questionnaire to assess dietary habits and garlic consumption. Blood bacterial DNA profile was estimated using qPCR and16S rRNA gene profiling. We derived odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) of IA and CRC according to garlic consumption from multiple conditional logistic regression. We used Mann-Whitney and chi-square tests to evaluate taxa differences in abundance and prevalence. RESULTS: The OR of CRC for medium/high versus low/null garlic consumption was 0.27 (95% CI = 0.11-0.66). Differences in garlic consumption were found for selected blood bacterial taxa. Medium/high garlic consumption was associated to an increase of Corynebacteriales order, Nocardiaceae family and Rhodococcus genus, and to a decrease of Family XI and Finegoldia genus. CONCLUSIONS: The study adds data on the protective effect of dietary garlic on CRC risk. Moreover, it supports evidence of a translocation of bacterial material to bloodstream and corroborates the hypothesis of a diet-microbiota axis as a mechanism behind the role of garlic in CRC prevention.

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.

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.

BACKGROUND AND AIM: Clinically relevant pancreatic leaks of jejunal-pancreatic anastomosis after pancreato-duodenectomy (PD) occur in 9-15% of cases. Endoscopic strategies for management of pancreatic fistula, may allow to avoid reoperation and shorten times for fistula closure, but are still understudied and not widely performed. Aim of the present paper is to describe different endoscopic techniques used to treat such conditions. METHODS: It was a retrospective, single centre, study. All patients who underwent endoscopic treatment for pancreatic leaks following PD between 1st January 2013 and 31th May 2019 at our Centre were reviewed. Depending on the morphology and severity of the leak, four main endoscopic techniques were performed: (1) trans-anastomotic intraductal pancreatic stent insertion; (2) lumen-apposing metal stent between the jejunal loop and the retroperitoneum toward the pancreatic stump insertion ("yoyo-stent"); (3) large calibre nose-to-retroperitoneum drain insertion; (4) when a wide damage of the jejunal wall or a coexistent biliary-jejunal leak were observed, triple metal stent insertion was performed as follow in order to close the defect: enteral fully-covered SEMS in the jejunal stump, a pancreatic metal stent into the Wirsung duct and a fully-covered SEMS across the bilio-digestive anastomosis, through the meshes of the enteral stent. In all cases, surgical drain was simultaneously retracted. RESULTS: We identified 13 patients who underwent endoscopic treatment for POPF after PD. In total, 5 patients underwent "Yoyo stent insertion", 3 with nose-to-collection drain placement and four patients were treated with triple-stent insertion; in only one patient intrapancreatic SEMS insertion was performed. Technical success was 100% and clinical success was 83.3%. Mean time for leak closure was 4.8 days (range 2-10). During the follow-up interval, no leak recurrences were observed. CONCLUSIONS: Our experience confirms efficacy and safety of endoscopic management of POPF following pancreatoduodenectomy management. Endoscopy should play a central role in this clinical scenario.

Coronavirus disease 2019 (COVID-19) is a major worldwide threat caused by a novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), rapidly spreading to a global pandemic. As of May 11, 2020, 4,176,346 cases have been reported worldwide, 219,814 in Italy, and of them, 81,871 occurred in the Lombardy region.1 Although the respiratory manifestations of COVID-19 have been widely described, the impact on the gastrointestinal (GI) system remains less clear. The reported prevalence of digestive symptoms ranges from 3% to 79%, depending on the setting,2-5 but data on GI endoscopic and histologic findings in COVID-19 patients are lacking. Therefore, the aim of this study is to describe the GI endoscopic and histologic findings in COVID-19 patients.

BACKGROUND: Endoscopic papillary balloon dilation (EPBD) was introduced to overcome the risk of adverse events associated with endoscopic sphincterotomy in the removal of common bile duct (CBD) stones. We performed a meta-analysis of randomized controlled trials (RCTs) comparing efficacy and safety of EPBD vs. endoscopic sphincterotomy, focusing on stone size, balloon diameter, and balloon dilation time. METHODS: A multiple database search was performed, including MEDLINE, EMBASE and Cochrane Library, from their inception date until October 2017.âRCTs comparing the efficacy and safety of EPBD vs. endoscopic sphincterotomy in the removal of CBD stones were included. Cumulative meta-analyses over time, and subgroup analyses according to stone size, and balloon diameter and dilation time were carried out. RESULTS: 25 RCTs met the inclusion criteria. Despite the cumulative meta-analysis showing a trend over time in favor of endoscopic sphincterotomy in studies published up to 2004, the conventional meta-analysis revealed that EPBD was equally efficacious compared with endoscopic sphincterotomy in stone removal at first attempt (odds ratio [OR] 0.95, 95â% confidence interval [CI] 0.65â-â1.38). Endoscopic sphincterotomy was superior to EPBD in terms of overall stone clearance (OR 0.65, 95â%CI 0.43â-â0.99) in studies published since 2002, but no differences emerged in studies using large (â≥â10âmm) balloons (OR 1.37, 95â%CI 0.72â-â2.62). No statistically significant difference in pancreatitis occurrence emerged between EPBD and endoscopic sphincterotomy (OR 1.35, 95â%CI 0.90â-â2.03). Pancreatitis was more common with EPBD than with endoscopic sphincterotomy in studies using balloonsâ<â10âmm (OR 1.78, 95â%CI 1.07â-â2.97), whereas no difference emerged in studies using large balloons (OR 0.84, 95â%CI 0.46â-â1.53). EPBD had lower rates of bleeding and cholecystitis. CONCLUSIONS: Our latest data confirm that EPBD is currently inferior to endoscopic sphincterotomy in terms of overall stone clearance. However, EPBD using large balloons (≥â10âmm) was as effective as endoscopic sphincterotomy, both in stone clearance and the need for endoscopic mechanical lithotripsy, without carrying an increased risk of pancreatitis.

BACKGROUND: Management of biliary adverse events (BAEs) after biliodigestive anastomosis is challenging. We propose a new endoscopic approach to improve BAEs in this clinical setting. METHODS: Patients who had BAEs after a hepaticojejunostomy with Roux-en-Y loop or a Whipple procedure underwent creation of an entero-enteral endoscopic bypass (EEEB) between the duodenal/gastric wall and the biliary jejunal loop under endoscopic ultrasound (EUS) and fluoroscopic guidance using specifically designed fully covered self-expandable metal stents. RESULTS: 32 consecutive patients underwent EEEB, which was successful in all but one patient. One procedural and five long-term mild adverse events occurred. Endoscopic retrograde cholangiography (ERC) through the EEEB successfully treated all types of BAEs in these patients. Disease recurred in two patients who were successfully re-treated through the EEEB. CONCLUSIONS: Our retrospective study showed that in patients with BAEs after biliodigestive anastomosis, EEEB is safe, feasible, and allows a successful long-term treatment of different BAEs in a tertiary referral center with high-level experience in both endoscopic retrograde cholangiopancreatography and EUS.

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 AND AIMS: There are 2 techniques described for selective bile duct guidewire cannulation, the touch (T) technique (engaging the papilla with a sphincterotome and then advancing the guidewire) and the no-touch (NT) technique (engaging the papilla only with the guidewire). The aim of this prospective, multicenter randomized study was to compare the outcomes of the 2 guidewire cannulation techniques. METHODS: Three hundred consecutive patients with naïve papillae were enrolled in 2 groups (150 to T group and 150 to NT group). A maximum of 15 biliary cannulation attempts, for no longer than 5 minutes, or a maximum of 5 unintentional cannulations of the pancreatic duct for each group were performed. If biliary cannulation failed, the patient was crossed over to the other technique with the same parameters. The primary outcome was the guidewire cannulation success rate using either the T or NT technique. Secondary outcomes were the number of attempts and cannulation duration, number of pancreatic duct cannulations, and adverse events. RESULTS: The primary cannulation rate was significantly higher in the T group compared with the NT group (88% vs 54%, P < .001), and the cannulation rate was significantly higher using the T technique compared with the NT technique also after crossover (77% vs 17%, P < .001). The mean number of cannulation attempts was 4.6 in the T group versus 5.5 in the NT group (P = .006), and the duration of cannulation before crossover (P < .001) and overall cannulation duration after crossover (P < .001) were significantly lower in the T group. The number of unintended pancreatic duct cannulations was statistically higher using the T technique compared with the NT technique (P = .037). The rates of adverse events did not significantly differ between the 2 groups. CONCLUSIONS: Our results clearly indicated that the T technique is superior to the NT technique for biliary cannulation.

BACKGROUND: Self-expandable metal stents (SEMS) are used for palliation of distal malignant biliary strictures, but the role of covered SEMS is less clear. We performed an up-to-date meta-analysis to compare the performance of covered and uncovered SEMS in patients with unresectable distal malignant biliary strictures. METHODS: A computerized medical search was performed using MEDLINE, EMBASE, and the Cochrane Library between 2000 and December 2016 to identify all randomized trials that compared covered with uncovered SEMS in patients with distal malignant biliary strictures. Primary outcomes were stent failure and patient mortality; secondary outcomes were stent dysfunction and adverse events. Pooled estimates were computed using the random effects model. RESULTS: Overall, 11 RCTs involving 1272 patients were included. The primary outcomes of stent failure and patient mortality did not differ significantly between covered and uncovered SEMS (hazard ratio [HR] 0.68, 95â% confidence interval [CI] 0.40â-â1.17; HR 0.89, 95â%CI 0.76â-â1.05, respectively). However, stent migration and sludge formation were much more common with covered SEMS (odds ratio [OR] 5.11, 95â%CI 1.84â-â14.17; OR 2.46, 95â%CI 1.37â-â4.43). The use of covered SEMS was associated with a lower rate of tumor ingrowth (OR 0.21, 95â%CI 0.09â-â0.50) but a higher rate of tumor overgrowth (OR 2.00, 95â%CI 1.15â-â3.48) compared with uncovered stents. The rates of procedure-related adverse events were similar in both groups. CONCLUSION: There was a risk reduction of about 32â% for both stent failure and patient mortality with covered SEMS but this difference was not significant. Migration and sludge rates were higher with covered SEMS, whereas tumor ingrowth was more likely with uncovered SEMS.âThe data show no added benefit of covered SEMS; further stent evolution is desirable.

BACKGROUND AND AIM: Some case reports have shown that fully covered self-expandable metal stents (FC-SEMS) are effective in cases of Stapfer Type II perforation as rescue treatment. The aim of the study was to assess the efficacy and safety of temporary placement of FC-SEMS as primary treatment for Type II perforations and review the literature regarding the use of FC-SEMS in this setting. PATIENTS AND METHOD: Retrospective analysis of consecutive patients with Type II perforation treated with immediate placement of FC-SEMS. Primary outcomes were need for surgery and mortality rate. Secondary outcomes were complications, technical and clinical success, time to post-operative feeding, length of the hospitalization and time to stent removal. RESULTS: Overall, 18 consecutive patients were enrolled (median age 71.5). All patients were treated with FC-SEMS (6-10 mm, 4-8 cm long). In all patients, there were no need for surgery, and no patient died. Technical and clinical success were achieved both in 100% of cases. The median time to stent removal was 43 (2-105) days. The median hospital stay was of 10 (4-21) days. Median time to post-operative feeding was 4 days (2-15). CONCLUSION: FC-SEMS placement could be a safe and effective treatment in Type II perforations and represent a valuable development and innovation of conservative treatment.

Dysphagia in patients with lung cancer is usually due to direct invasion from bronchogenic carcinomas or nodal localizations, while metastases from distant lung neoplasms are considered rare. We report a case of a smooth esophageal narrowing secondary to intramural metastasis from pulmonary adenocarcinoma in a patient with no previous history of neoplasia. Since standard linear echoendoscope could not overpass the malignant stricture, we obtained a histological diagnosis by fine-needle aspiration biopsy using an echobronchoscope (EBUS), due to its lower diameter. The EBUS scope represents a valuable tool to obtain cytological specimens in patients with esophageal strictures.

Cricopharyngeal myotomy with flexible endoscope is a well-known and safe treatment for Zenker's diverticulum. We describe hereafter how we perform this flexible endotherapy. From January 2011 to January 2017, we treated 28 patients with this endotherapy. Our technique is described step-by-step in the paper: the main principle is to perform an endoscopic cut of the diverticular septum and cricopharyngeal muscle's fibers (see the video). We describe an objective measurement of the cutting length and depth of the myotomy. Technical success was achieved in all the patients. As to clinical success, 76.2% of patients showed a significant improvement and relevant disappearance of preoperative dysphagia. The present follow-up ranges from 6 months to 5 years. This flexible endoscopic technique can overcome some limitations of rigid endoscopic technique (i.e., upper teeth protrusion, inadequate jaw opening, or limited neck mobility). The main indication was based on clinical presentation and referred to the diverticular dimensions between 2 and 5 cm. Tips for the technique are described in the paper. This variant of cricopharyngeal myotomy with flexible endoscopy is feasible and effective for the treatment of Zenker's diverticulum in selected patients.
