RESUMO

INTRODUCTION: We assessed the prevalence and clinical outcomes of segmental colitis associated with diverticulosis (SCAD) in patients with newly diagnosed diverticulosis. METHODS: A 3-year international, multicenter, prospective cohort study was conducted involving 2,215 patients. RESULTS: SCAD diagnosis was posed in 44 patients (30 male patients; median age: 64.5 years; prevalence of 1.99%, 95% confidence interval, 1.45%-2.66%). Patients with SCAD types D and B showed worse symptoms, higher fecal calprotectin values, needed more steroids, and reached less likely complete remission. DISCUSSION: Although SCAD generally had a benign outcome, types B and D were associated with more severe symptoms and worse clinical course.

RESUMO

OBJECTIVE: To validate Lyon Consensus criteria for diagnosing gastro-oesophageal reflux disease (GORD) by reflux monitoring. DESIGN: Manual review of impedance-pH tracings from patients with proton pump inhibitor (PPI)-dependent heartburn, evaluated off PPI. Acid exposure time (AET) thresholds defined by the Lyon Consensus and impedance parameters were investigated, namely, total refluxes (TRs), postreflux swallow-induced peristaltic wave (PSPW) index and mean nocturnal baseline impedance (MNBI). RESULTS: The study included 488 patients, 178 (36%) with normal (<4%) AET, 89 (18%) with inconclusive (4%-6%) AET and 221 (45%) with abnormal (>6%) AET, alongside with 70 healthy controls. At receiver operating characteristic analysis, area under curve was 0.89, 0.95 and 0.89 for TRs, PSPW index and MNBI, respectively, and threshold values were 40, 50% and 2000 Ω; the 4% physiological AET threshold defined by the Lyon Consensus showed 100% specificity but 63% sensitivity. The thresholds defined for impedance parameters were validated against AET by means of ordered logistic regression, being in concordance with the 4% AET threshold (OR 2.5 for TRs, 18.9 for PSPW index and 5.7 for MNBI). TRs positivity and concordant PSPW index/MNBI positivity were found in 80%-90% of patients in the abnormal AET group, in 73%-74% of cases in the inconclusive AET group and in 28%-40% of cases in the group with normal AET. CONCLUSIONS: Our results show the overall validity of the Lyon Consensus approach to GORD diagnosis. Adding evaluation of impedance parameters, namely, TRs, PSPW index and MNBI to AET appraisal, substantially improves the diagnostic yield of reflux monitoring.

RESUMO

OBJECTIVE: To investigate the predictive value of the Diverticular Inflammation and Complication Assessment (DICA) classification and to develop and validate a combined endoscopic-clinical score predicting clinical outcomes of diverticulosis, named Combined Overview on Diverticular Assessment (CODA). DESIGN: A multicentre, prospective, international cohort study. SETTING: 43 gastroenterology and endoscopy centres located in Europe and South America. PARTICIPANTS: 2215 patients (2198 completing the study) at the first diagnosis of diverticulosis/diverticular disease were enrolled. Patients were scored according to DICA classifications. INTERVENTIONS: A 3-year follow-up was performed. MAIN OUTCOME MEASURES: To predict the acute diverticulitis and the surgery according to DICA classification. Survival methods for censored observation were used to develop and validate a novel combined endoscopic-clinical score for predicting diverticulitis and surgery (CODA score). RESULTS: The 3-year cumulative probability of diverticulitis and surgery was of 3.3% (95% CI 2.5% to 4.5%) in DICA 1, 11.6% (95% CI 9.2% to 14.5%) in DICA 2 and 22.0% (95% CI 17.2% to 28.0%) in DICA 3 (p<0.001), and 0.15% (95% CI 0.04% to 0.59%) in DICA 1, 3.0% (95% CI 1.9% to 4.7%) in DICA 2 and 11.0% (95% CI 7.5% to 16.0%) in DICA 3 (p<0.001), respectively. The 3-year cumulative probability of diverticulitis and surgery was ≤4%, and ≤0.7% in CODA A; <10% and <2.5% in CODA B; >10% and >2.5% in CODA C, respectively. The CODA score showed optimal discrimination capacity in predicting the risk of surgery in the development (c-statistic: 0.829; 95% CI 0.811 to 0.846) and validation cohort (c-statistic: 0.943; 95% CI 0.905 to 0.981). CONCLUSIONS: DICA classification has a significant role in predicting the risk of diverticulitis and surgery in patients with diverticulosis, which is significantly enhanced by the CODA score. TRIAL REGISTRATION NUMBER: NCT02758860.

RESUMO

BACKGROUND AND AIMS: Electrocautery-tip lumen-apposing metal stents (EC-LAMSs) have extended the indications of therapeutic EUS. We aimed to retrospectively evaluate safety and technical and clinical success of a newly developed EC-LAMS, the Hot-Spaxus (Taewoong Medical Co, Gimpo, Korea), for various EUS-guided procedures. METHODS: We included and retrospectively analyzed consecutive patients at 8 tertiary care referral centers who had undergone EUS interventional procedures using the Hot-Spaxus between October 2018 and February 2021. RESULTS: Of 58 included patients (male-to-female, 36:22; mean age, 63.5 ± 14.9 years), 29 had undergone pancreatic fluid collection drainage (50%), 22 (37.9%) biliary drainage for malignant distal obstruction, 3 (5.1%) gallbladder drainage for acute cholecystitis, 3 gastroenteroanastomoses, and 1 (1.7%) pelvic collection drainage. Technical success was achieved in 54 of 58 patients (93.1%) and clinical success in all 58. Adverse events occurred in 6 patients (11.1%): 2 early (3.7%), 1 late (1.8%), and 3 long term (5.6%). The outcomes were similar to those observed in a control group of patients treated with the Hot-Axios (Boston Scientific, Marlborough, Mass, USA), the other available EC-LAMS. CONCLUSIONS: Our study showed that the novel EC-LAMS has high technical and clinical success rates for various interventional EUS indications. Future multicenter prospective studies will better clarify the role of this new EC-LAMS for different indications.

RESUMO

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.

RESUMO

BACKGROUND: The management of difficult lithiasis of common bile duct (CBD) often requires a multimodal approach. Fully Covered Metal Stents (FCSEMS) could fragment the stones, dilate strictures of the CBD and progressively enlarge the papillary orifice. The aim of the study was to evaluate the efficacy of FCSEMS in the treatment of difficult lithiasis of CBD. METHODS: All consecutive cases of difficult lithiasis of CBD after an attempt of clearance with complete sphincterotomy were retrospectively considered from 2009 to 2019. Intrahepatic lithiasis cases were excluded. Multivariable analysis (stepwise logistic regression if p value < 0.1 at univariable analysis) was made to understand factors associated with efficacy of FCSEMS in difficult lithiasis of CBD. RESULTS: 163 cases of difficult lithiasis over 1516 cases of lithiasis of CBD (incidence of 11%) were considered. Among eligible patients, 96 (mean age 78 ± 11.9 years, 43% males) placed a FCSEMS during the first ERCP. Mean diameter of stone was 17.5 ± 5.5 mm. An attempt of dilation during the same procedure was made in 18% cases. After removal of the stent, 52 (54%) patients had complete clearance of CBD at cholangiography. The rest of patients (44), subsequently underwent multimodal treatment (final success of 95%). After logistic regression, variables positively associated with clearance of CBD were sex male (OR 3.5) and stent permanence ≥ 30 days (OR 3.2). Diameter of the stone ≥ 2 cm was associated with failure (OR 0.2). 7 post-ERCP pancreatitis, 6 post-sphincterotomy bleeding and 3 cholangitis occurred. CONCLUSIONS: FCSEMS are useful in the approach of difficult lithiasis of CBD with no significant adverse events associated.

RESUMO

BACKGROUND AND AIM: In presence of malignant dysphagia, in patients unfit for surgery, the placement of a self-expandable metal stent (SEMS) represents a safe and effective palliative treatment. Esophageal stents (ES) present an over-the-wire mechanism where the stent is deployed under X-ray control. Recently a through-the-scope (TTS) ES was launched. The aim of our retrospective study is to assess the technical and clinical success of the new TTS-ES. MATERIALS AND METHODS: Patients with malignant dysphagia caused by esophageal cancer or ab-extrinsic compression, who underwent TTS esophageal stent in six Italian endoscopic referral centers, were retrospectively reviewed. RESULTS: A total of 40 patients were enrolled. TTS stent placement was successful in 39/40 patients (97.5%). 31 patients had an Ogilvie score of 4, nine an Ogilvie 3. After 2 weeks from stent placement 29 reported Ogilvie score of 0, eight a score of 1. None of the patients developed retrosternal pain requiring drugs. No patient experienced perforation, bleeding or migration. A total of seven patients (18%) developed dysphagia as late adverse event (AE). CONCLUSION: Through-the-scope ES presented less AEs, in terms of bleeding and perforation, if compared to the previous published data. An anti-migration system could be helpful, especially when the stent is placed for "ab-extrinseco" malignant dysphagia.

RESUMO

OBJECTIVES: Role of reflux and mechanisms of response to proton pump inhibitor (PPI) therapy in eosinophilic esophagitis (EoE) have not yet been fully elucidated. Comprehensive assessment by impedance-pH monitoring could clarify these issues. METHODS: Prospective multicenter study comparing EoE patients with healthy controls and gastroesophageal reflux disease cases. Patients with EoE were evaluated off- and on PPI; responsiveness was assessed by histology. Impedance-pH appraisal included chemical clearance, assessed with the postreflux swallow-induced peristaltic wave (PSPW) index, and mucosal integrity measured with mean nocturnal baseline impedance (MNBI). RESULTS: Sixty consecutive patients with EoE were compared with 60 age- and sex-matched healthy controls and 60 subjects with gastroesophageal reflux disease. The number of total refluxes was higher, while the PSPW index was lower in patients with EoE than in healthy controls. Off PPI, a lower MNBI gradient between the mid and distal esophagus distinguished 20 patients with PPI-refractory EoE from 40 patients with PPI-responsive EoE and was a predictor of PPI failure. On PPI, a lower PSPW index was the sole reflux parameter distinguishing PPI-refractory from PPI-responsive EoE; all reflux parameters improved in PPI-responsive patients, whereas the PSPW index was not modified in PPI-refractory cases and was independently associated with PPI-responsiveness. MNBI in the distal and mid esophagus improved much more in PPI-responsive than in PPI-refractory EoE. DISCUSSION: Reflux plays a role in the pathogenesis of EoE, more relevant in PPI-responsive cases. Low impedance gradient between the mid and distal esophagus may be useful to predict PPI refractoriness. PPIs mainly act by improving chemical clearance, i.e., by an antireflux action supporting long-term prescription in PPI-responsive EoE.

RESUMO

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.

RESUMO

BACKGROUND AND AIMS: Self-expandable metal stents (SEMSs) are used to relieve malignant biliary obstructions. We aimed to compare stent patency, the adverse events rate, and overall survival of covered versus uncovered self-conformable metal stents in patients with primary malignant extrahepatic biliary strictures, not eligible for surgery. METHODS: This is a multicenter randomized trial analyzing 158 patients with inoperable distal malignant biliary obstruction conducted in 5 Italian referral centers between December 2014 and October 2016. Seventy-eight patients were randomized to receive a fully covered SEMS (FCSEMS), and 80 patients received uncovered SEMSs (USEMSs). Data from 148 (72 FCSEMSs and 76 USEMSs) of 158 patients were analyzed. RESULTS: Median time of stent patency was lower for FCSEMSs (240 days vs 541 days for USEMSs; P = .031). Adverse events occurred with 19 FCSEMSs (26.4%) and 10 USEMSs (13.2%); P = .061. The main causes of FCSEMS dysfunction were migration (7% vs 0% in the USEMS group) and early occlusion mainly because of sludge or overgrowth; late stent occlusion because of tumor ingrowth occurred in 13.2% of patients in the USEMS group. There were no significant differences either in levels of conjugated bilirubin improvement or in overall survival between the FCSEMS and USEMS groups. Median survival was 134 days in the FCSEMS group and 112 days in the USEMS group (P = .23). CONCLUSION: The number of stent-related adverse events was higher, although not significantly, among patients in the FCSEMS group. FCSEMSs had a significantly higher rate of migration than USEMSs, and stent occlusion occurred earlier. A significant difference in the patency rate was observed in favor of the USEMS group.

RESUMO

BACKGROUND: Clinical trials have shown a good efficacy of the "three-in-one" formulation of bismuth quadruple therapy (BQT) for Helicobacter (H.) pylori eradication. We aimed to assess the efficacy and safety of the three-in-one BQT in clinical practice, and investigate the effect of probiotic supplementation, in Italy. MATERIALS AND METHODS: A retrospective database, multicentre observational study was conducted in seven Italian Hospitals. Consecutive H. pylori-positive patients who received the three-in-one BQT for 10 days were included in the analysis. H. pylori eradication was assessed by histology, 13 C-urea breath test, or stool antigen test. Compliance and adverse events were evaluated by interview. RESULTS: A total of 376 patients were included in the intention-to-treat (ITT) and 352 in the per protocol (PP) analyses. One hundred and ninety-three subjects received probiotics supplementation. Overall, eradication rates were 90.2% (95% Confidence Interval (CI):86.7-93.0) in ITT and 94.6% (95% CI: 91.7-96.7) in PP analyses. The compliance was good (≥90% of treatment taken) in 94.9% of patients. The proportion of patients with a good compliance was not different with and without probiotics supplementation (94.8% vs 95.1%). Eradication rates were equally high for first-line (91.4%), second-line (87.5%), and third-line treatments (91.7%) in the ITT analysis (P = .48). Adverse events were reported by 32.4% of patients, but only 6.1% of patients discontinued treatment. CONCLUSIONS: The three-in-one BQT is highly effective and well tolerated for H. pylori eradication in daily clinical practice. Probiotics supplementation fails to improve compliance.

RESUMO

BACKGROUND AND AIMS: Radiofrequency ablation (RFA) is a well-recognized local ablative technique applied in the treatment of different solid tumors. Intraoperative RFA has been used for non-metastatic unresectable pancreatic ductal adenocarcinoma (PDAC), showing increased overall survival in retrospective studies. A novel RFA probe has recently been developed, allowing RFA under endoscopic ultrasound (EUS) guidance. Aim of the present study was to assess the feasibility and safety of EUS-guided RFA for unresectable PDACs. METHODS: Patients with unresectable non-metastatic PDAC were included in the study following neoadjuvant chemotherapy. EUS-guided RFA was performed using a novel monopolar 18-gauge electrode with a sharp conical 1 cm tip for energy delivery. Pre- and post-procedural clinical and radiological data were prospectively collected. RESULTS: Ten consecutive patients with unresectable PDAC were enrolled. The procedure was successful in all cases and no major adverse events were observed. A delineated hypodense ablated area within the tumor was observed at the 30-day CT scan in all cases. CONCLUSIONS: EUS-guided RFA is a feasible and safe minimally invasive procedure for patients with unresectable PDAC. Further studies are warranted to demonstrate the impact of EUS-guided RFA on disease progression and overall survival.

RESUMO

BACKGROUND AND AIM: The over-the-scope clip (OTSC) system is a recently developed endoscopic device. In the last few years, it has been successfully used for severe bleeding or deep wall lesions, or perforations of the gastrointestinal (GI) tract. We hereby report a series of patients with post-pancreaticogastrostomy pancreatic fistula in whom OTSC were used as endoscopic treatment. METHODS: From January 2012 to July 2015, we prospectively collected data on cases of postoperative pancreatic fistula. These patients underwent pancreaticoduodenectomy in a high-volume center of hepatobiliopancreatic surgery. After conservative management, OTSC closure was done by single skilled operators in anesthesiologist-assisted deep sedation. RESULTS: A total of seven patients were enrolled. According to the International Study Group of Pancreatic Surgery criteria, we observed grade B postoperative pancreatic fistula in all cases. All patients were treated with 12/6 t-type OTSC. In two cases, a second clip was successfully applied to a second site adjacent to the original closure site. In all cases, subsequent fluoroscopy showed no contrastographic spreading through the wall. There were no complications related to the procedure itself, not from the endoscopy point of view, nor from the anesthesiological perspective. There were no device malfunctions. Further clinical and endoscopic evaluation was made 8 weeks later and showed no fistula or anastomotic defect recurrence. No patients required additional endoscopic or interventional procedures. CONCLUSION: In consideration of clinical and technical success, OTSC placement in POPF seems to be effective, safe and technically relatively easy to carry out.

RESUMO

BACKGROUND & AIMS: Analyses of impedance parameters such as the post-reflux swallow-induced peristaltic wave (PSPW) index and the mean nocturnal baseline impedance (MNBI) have been proposed to increase the accuracy of diagnosis of reflux disease. We assessed whether these improve the diagnostic yield of impedance pH monitoring of reflux disease. METHODS: We performed a prospective study of consecutive patients with proton pump inhibitor-responsive heartburn who underwent 24-hour impedance pH monitoring at hospitals in Italy from January 2011 through December 2013. Reviewers blindly analyzed off-therapy impedance pH tracings from 289 patients with proton pump inhibitor-responsive heartburn, 68 with erosive reflux disease and 221 with non-erosive reflux disease (NERD), along with 50 healthy individuals (controls). The PSPW index, the MNBI, the esophageal acid exposure time, the number of total refluxes, and the bolus exposure were calculated, as well as the symptom association probability (SAP) and the symptom index (SI). RESULTS: In receiver operating characteristic analysis, the area under curve of the PSPW index (0.977; 95% confidence interval, 0.961-0.993) was significantly greater than that of the other impedance pH parameters in identifying patients with reflux disease (P < .001). The PSPW index and the MNBI identified patients with erosive reflux disease with the highest level of sensitivity (100% and 91%, respectively), as well as the 118 pH-positive (99% and 86%) and 103 pH-negative (77% and 56%) cases of NERD. The PSPW index and the MNBI identified pH-negative NERD with the highest level of sensitivity; values were 82% and 52% for the 65 SAP-positive and/or SI-positive cases and 68% and 63% for the 38 SAP-negative and SI-negative cases. Diagnoses of NERD were confirmed by pH-only criteria, including those that were positive on the basis of the SAP or SI, for 165 of 221 cases (75%) and by impedance pH criteria for 216 of 221 cases (98%) (P = .001). CONCLUSIONS: The PSPW index and the MNBI increase the diagnostic yield of impedance pH monitoring of patients with reflux disease. Analysis of impedance pH data by calculating the PSPW index and the MNBI can increase the accuracy of diagnosis of patients with reflux disease, compared with pH-only data.

RESUMO

Colonic diverticula are one of the most frequent conditions found during the endoscopic examination of the lower digestive tract, interestingly in >70% of people after 80 years old. Of them, only a few percentage develop complications such as acute diverticulitis or diverticular bleeding. Up to now, colonoscopy represents the most important diagnostic and therapeutic tool on the hands of the clinicians. On the basis of this the need for a standardized and reproducible approach is now emerging. This short review article is tasked to point out some open issues concerning the role of colonoscopy in diverticular disease.

RESUMO

BACKGROUND: A number of patients with inoperable pancreatic cancer may concurrently complain of pain, biliary obstruction, and duodenal stenosis. Endoscopic palliative treatments and opioid therapy are generally performed in these patients. The study aimed to assess the efficacy and safety of a multimodal 'one-Session Three Endoscopic Procedures' (one-STEP) to simultaneously treat cholestasis, restore duodenal transit, and achieve pain relief in selected patients with advanced pancreatic cancer. METHODS: Selected patients diagnosed with an advanced pancreatic cancer presenting with biliary obstruction, duodenal stenosis, and severe pain treated with the one-STEP were considered. The one-STEP endoscopic approach included biliary and duodenal stenting, and EUS-guided celiac plexus neurolysis. The technical success rate, complications, pain relief, and opioid use at follow-up were assessed. RESULTS: A total of 15 patients were treated. The one-STEP was successful in 13 (87 %) cases, while it failed in two patients due to the impossibility of dilating the neoplastic mass for creating a fistula. No endoscopy-related complications occurred. The median of pain intensity was 8 (range 7-10) at entry and significantly decreased to 2 (range 2-4) 72 h following celiac plexus neurolysis. At follow-up (median survival 4 months; range 3-8), only 3 (20 %) needed of narcotic treatment in the last period. CONCLUSIONS: The multimodal one-STEP is an effective and safe endoscopic approach for palliative treatment of biliary and duodenal stenosis, and for relieving chronic pain in patients with advanced pancreatic cancer.
