RÉSUMÉ
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.

AIM: To investigate the relationship between pathological oropharyngeal (OP) acid exposure and esophageal motility in patients with extra-esophageal syndromes. METHODS: In this prospective study we enrolled consecutive outpatients with extra-esophageal symptoms suspected to be related to gastroesophageal reflux disease (GERD). We enrolled only patients with a reflux symptom index (RSI) score-higher than 13 and with previous lung, allergy and ear, nose and throat evaluations excluding other specific diagnoses. All patients underwent 24-h OP pH-metry with the Dx probe and esophageal high-resolution manometry (HRM). Patients were divided into two groups on the basis of a normal or pathological pH-metric finding (Ryan Score) and all manometric characteristics of the two groups were compared. RESULTS: We examined 135 patients with chronic extra-esophageal syndromes. Fifty-one were considered eligible for the study. Of these, 42 decided to participate in the protocol. Patients were divided into two groups on the basis of normal or pathological OP acid exposure. All the HRM parameters were compared for the two groups. Significant differences were found in the median upper esophageal sphincter resting pressure (median 71 mmHg vs 126 mmHg, P = 0.004) and the median proximal contractile integral (median 215.5 cmâ¢mmHgâ¢s vs 313.5 cmâ¢mmHgâ¢s, P = 0.039), both being lower in the group with pathological OP acid exposure, and the number of contractions with small or large breaks, which were more frequent in the same group. This group also had a larger number of peristaltic contractions with breaks in the 20 mmHg isobaric contour (38.7% vs 15.38%, P < 0.0001). CONCLUSION: In patients with suspected GERD-related extra-esophageal syndromes pathological OP acid exposure was associated with weaker proximal esophageal motility.

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.

BACKGROUND: Colorectal cancer screening may reduce disease-related mortality by early-stage detection of cancers. AIMS: To study the effect of a single immunochemical faecal occult blood test (i-FOBt) screening round on reduction in colorectal cancer-related-mortality among average risk subjects. METHODS: Comparison of 5-year mortality rates in 3 cohorts from a Northern Italian province: (1) colorectal cancers detected at the 1st biennial round of a mass-screening programme targeting 50-69 years old subjects, (2) non-screening cancers symptomatically diagnosed during the same time period, and (3) cancers detected in the pre-screening biennium. Multivariate analyses were performed with the Cox regression model including tumour node metastasis (TNM) stage at diagnosis, anatomical distribution of cancers, age at diagnosis, gender and patient group. Kaplan-Meyer survival estimates and log-rank test for equality of survivor functions were calculated. RESULTS: Stage distribution significantly differed between screening and non-screening colorectal cancers: 73% of screen-detected colorectal cancers were stages I and II versus 43% and 40% of non-screening and pre-screening colorectal cancers. Cumulative 5-year mortality rate was significantly lower in screening compared to non-screening or pre-screening colorectal cancers patients (19% versus 37% and 41%, p < 0.001). CONCLUSIONS: Colorectal cancers were detected at earlier stages in i-FOBT-positive subjects in comparison with non-screening patients; colorectal cancers found at screening had a significantly improved 5-year survival.

BACKGROUND: Transoral incisionless fundoplication (TIF) with the EsophyX™ device creates an antireflux valve with good functional results in patients with gastro-esophageal reflux disease (GERD). The aim of this study was to assess the long-term effect of TIF 2.0 on pathological reflux and symptoms in GERD patients with daily dependence on proton pump inhibitors (PPI). METHODS: Fifty patients underwent TIF. All underwent GERD-HRQL and GERD-QUAL questionnaires, upper GI endoscopy, esophageal manometry, and 24-h pH-impedance before and 6, 12, and 24 months after TIF, and subsequent yearly clinical re-evaluation. RESULTS: Patients were followed for up to six years (mean 52.7 ± 19.7 months). In all, 83.7, 79.6, 87.8, and 84.4% of patients stopped or halved the PPI therapy 6, 12, 24, and 36 months after TIF. Three-year figure remained stable up to 6 years. Symptom scores off PPI were significantly lower at 6, 12, 24, and 36 months. At 6 months, Hill's grade I of the newly created valve persisted in all pre-procedure Hill's grade I patients, in 66.7% of grade II and 58.3% of grade III. This figure remained substantially unchanged at 12 and 24 months, too. Impedance monitoring indicated significantly fewer total and acid refluxes after treatment (p = 0.01). Factors predicting good outcomes were pre-procedure Hill's grade I-II, no hiatal hernia or hernia ≤2 cm (p = 0.03), absence of ineffective esophageal motility (p < 0.0001), and number of fasteners deployed (p = 0.01). CONCLUSIONS: TIF by the EsophyX achieved lasting elimination of daily dependence on PPI in 75-80% of patients for up to 6 years. TIF seems an effective therapy for selected symptomatic GERD patients.

INTRODUCTION: A multicenter study with a limited sample size found that absence of esophagitis, presence of functional digestive disorders, and overweight were associated with proton pump inhibitors (PPI) failure. AIM: To assess clinical and reflux patterns associated with PPI-responsiveness. MATERIALS AND METHODS: Patients with typical gastroesophageal reflux disease (GORD) symptoms had 24 hours pH-impedance monitoring off therapy. Responders had <2 days of symptoms per week while on standard-dose/double-dose PPI. Clinical and reflux parameters were considered for analysis. RESULTS: A total of 514 patients were included (267 women), 185 patients were considered PPI responders, and 329 were considered nonresponders. In the whole population, the only significant factor in the prediction of responsiveness to PPI at the multivariate analysis was the presence of esophagitis (P=0.028). The factors identified as significant in patients with a pathologic acid exposure (142 patients) in the prediction of responsiveness to PPI were overweight (body mass index >25 kg/m(2)) and the presence of esophagitis (P=0.019 and 0.043, respectively). CONCLUSIONS: We confirm that no reflux pattern demonstrated by 24 hours pH-impedance monitoring is associated to PPI response in GORD patients. Presence of esophagitis in the whole population and overweight in patients with pathologic GORD, but not dyspepsia, are strongly associated with PPI-responsiveness.

BACKGROUND: Lesion detection rate during colonoscopy may be influenced by the endoscopist's experience. EPK-i system colonoscopy (i-Scan) can improve mucosal and vascular visualization for detecting lesions. AIM: To compare mucosal lesions detection rate and the withdrawal time of the instrument among non-expert and expert endoscopists. METHODS: Colonoscopy records of all consecutive patients undergoing first HD+ with i-Scan- or SWL-equipped colonoscopy for colorectal cancer screening over a twelve-month period were evaluated, in a "post hoc" analysis. RESULTS: 542 colonoscopies (389 HD+ with i-Scan; 153 SWL): expert and non-expert endoscopists did respectively 272 and 117 HD+ with i-Scan and 83 and 70 SWL colonoscopies. Expert endoscopists did more i-Scan colonoscopies than non-experts (p=0.006). In the SWL procedures, the experts detected mucosal lesions in more colonoscopies than non-experts (61/22 vs. 23/47, p=0.0001) and found a significantly higher mean number of lesions (1.34 vs. 0.47; p=0.0001). Experts detected more or less the same mean number of lesions with both imaging techniques, while among non-experts detection with HD+ with i-Scan was significantly better than with SWL imaging (1.39 vs. 0.47; p=0.0001). CONCLUSIONS: HD+ with i-Scan imaging enables less skilled endoscopists to achieve results comparable to those of experienced ones in detecting mucosal lesions.

OBJECTIVE: Current methods of measuring pharyngeal pH are problematic. The aim of the study was to assess the ability of the oropharyngeal pH monitoring (Restech) in predicting the response to proton pump inhibitor (PPI) therapy in patients with gastroesophageal reflux disease-related laryngopharyngeal symptoms. STUDY DESIGN: The study design is prospective and uncontrolled. METHODS: Twenty-two consecutive naive patients with chronic laryngeal symptoms were enrolled. Reflux symptom index, fibrolaryngoscopy, and 24-hour oropharyngeal pH monitoring were performed. Both patients and laryngoscopist were blinded by the results of Restech. All the patients were given a 3-month therapy with pantoprazole of 40mg twice a day and then repeated both the reflux symptom index and fibrolaryngoscopic evaluation. Patients were considered as responders if a five-point decrease in symptom score was recorded. RESULTS: Thirteen of the 22 patients (59.1%) responded to therapy. Laryngoscopic findings did not correlate with the clinical improvement after the 3 months of PPI. Nine patients (40.9%) had a pathologic Restech study, and all resulted responsive to PPI; nine patients (40.9%) with a negative Restech were nonresponsive to PPI, and four patients (18.2%) despite a negative Restech resulted responsive to therapy. Responsive patients showed both a higher oropharyngeal acid exposure in orthostatic position and a higher Ryan score, compared with nonresponders (49.74±58.11 vs 2.12±0.0, P=0.002). Considering responsiveness to medical therapy as the gold standard of laryngopharyngeal reflux (LPR) for the diagnosis of LPR, Restech showed a sensitivity of 69% and a specificity of 100%. CONCLUSIONS: The high specificity and reasonable sensitivity of this technique make the Restech an interesting tool before therapy of patients with pharyngoesophageal reflux.

AIM: To investigate if high-definition (HD) colonoscope with i-Scan gave a higher detection rate of mucosal lesions vs standard white-light instruments. METHODS: Data were collected from the computerized database of the endoscopy unit of our tertiary referral center. We retrospectively analyzed 1101 consecutive colonoscopies that were performed over 1 year with standard white-light (n = 849) or HD+ with i-Scan (n = 252) instruments by four endoscopists, in an outpatient setting. Colonoscopy records included patients' main details and family history for colorectal cancer, indication for colonoscopy (screening, diagnostic or surveillance), type of instrument used (standard white-light or HD+ plus i-Scan), name of endoscopist and bowel preparation. Records for each procedure included whether the cecum was reached or not and the reason for failure, complications during or immediately after the procedure, and number, size, location and characteristics of the lesions. Polyps or protruding lesions were defined as sessile or pedunculated, and nonprotruding lesions were defined according to Paris classification. For each lesion, histological diagnosis was recorded. RESULTS: Eight hundred and forty-nine colonoscopies were carried with the standard white-light video colonoscope and 252 with the HD+ plus i-Scan video colonoscope. The four endoscopists did 264, 300, 276 and 261 procedures, respectively; 21.6%, 24.0%, 21.7% and 24.1% of them with the HD+ plus i-Scan technique. There were no significant differences between the four endoscopists in either the number of procedures done or the proportions of each imaging technique used. Both techniques detected one or more mucosal lesions in 522/1101 procedures (47.4%). The overall number of lesions recognized was 1266; 645 in the right colon and 621 in the left. A significantly higher number of colonoscopies recognized lesions in the HD+ plus i-Scan mode (171/252 = 67.9%) than with the standard white-light technique (408/849 = 48.1%) (P < 0.0001). HD+ with i-Scan colonoscopies identified more lesions than standard white-light imaging (459/252 and 807/849, P < 0.0001), in the right or left colon (mean ± SD, 1.62 ± 1.36 vs. 1.33 ± 0.73, P < 0.003 and 1.55 ± 0.98 vs. 1.17 ± 0.93, P = 0.033), more lesions < 10 mm (P < 0.0001) or nonprotruding (P < 0.022), and flat polyps (P = 0.04). The cumulative mean number of lesions per procedure detected by the four endoscopists was significantly higher with HD+ with i-Scan than with standard white-light imaging (1.82 ± 2.89 vs. 0.95 ± 1.35, P < 0.0001). CONCLUSION: HD imaging with i-Scan during the withdrawal phase of colonoscopy significantly increased the detection of colonic mucosal lesions, particularly small and nonprotruding polyps.

Gastro-oesphageal reflux disease results primarily from the loss of an effective antireflux barrier, which forms a mechanical barrier against the retrograde movement of gastric content. This review describes the technique of performing a transoral incisionless fundoplication with the EsophyX® device. Transoral incisionless fundoplication reconfigures the tissue so as to establish serosa-to-serosa plications which include the muscular layers, and construct 3-5 cm long valves 200-300° in circumference. The steps of the technique, as well as complications and their management are described in detail, and a recent literature review is also provided. At present, available prospective cohort studies indicate that transoral incisionless fundoplication using the EsophyX® device may be effective in approximately half PPI-responsive gastro-oesphageal reflux disease for up to 3 years' follow-up, without troublesome procedure-related persistent side effects.

INTRODUCTION: Transoral incisionless fundoplication (TIF) with the EsophyX(™) device is reported to be effective for creating a continent gastroesophageal valve and for good functional results, as measured by pH impedance in patients with gastroesophageal reflux disease (GERD). The aim of this study is to assess the long-term effect of TIF in patients with symptomatic GERD. PATIENTS AND METHODS: TIF 2.0 fundoplication was done in 42 consecutive patients. All were studied with GERD-HRQL and GERD-QUAL questionnaires, upper gastrointestinal (GI) endoscopy, esophageal manometry, and 24 h pH impedance before and at 6, 12, and 24 months after TIF. RESULTS: In all, 35 patients completed 6-month follow-up; 21 (60.0%) completely stopped proton pump inhibitor (PPI) therapy, 6 (17.1%) more than halved it, and 8 (22.9%) continued with the same dose as before the procedure. There were 26 patients with complete 24-month follow-up; 11 (42.3%) completely stopped PPI therapy, 7 (26.9%) more than halved it, and 8 (30.8%) were taking the same dose as before the procedure. Hiatal hernia and ineffective esophageal motility seemed to raise the risk of recurrence of symptoms (p = 0.02 and p < 0.001, respectively). The number of fasteners deployed during TIF was the only factor predictive of successful outcome (p = 0.018). CONCLUSIONS: TIF using the EsophyX device allowed withdrawal or reduction of PPI in about 77% of patients at 6-month follow-up and about 69% at 24 months. Larger number of fasteners deployed during TIF was predictive of positive outcome; pre-TIF ineffective esophageal motility and hiatal hernia raised the risk of recurrence of GERD symptoms, but were not significant from a prospective point of view.

BACKGROUND: Repeated attempts at cannulating the papilla of Vater and "needle-knife" precut sphincterotomy are independent risk factors for post-ERCP pancreatitis. Whether precut alone or repeated attempts at cannulation is the culprit factor in the development of post-ERCP pancreatitis remains controversial. AIM: To retrospectively assess the role of precutting and multiple cannulation in the occurrence of post-ERCP pancreatitis in a consecutive series of patients with bile stone disease. METHODS: 2004 patients who had undergone endoscopic retrograde cholangio-pancreatography over a 9-year period for bile stones were evaluated. Pancreatitis rate was assessed in relation to the number of cannulation attempts (<10 and ≥10) and precutting. RESULTS: Procedures were successful in 1878 patients (93.7%). Cannulation was done without precutting in 1717 cases and with in 161. Pancreatitis occurred in 2.7% of patients who had undergone biliary cannulation without precutting and in 6.5% with (p=0.006). It was lower with <10 attempts than with ≥10 (p<0.0001), either without (p<0.0001) or with precutting (p<0.01). Pancreatitis rate did not differ without and with precutting when <10 attempts at cannulation were done, whilst it was lower when precut was done before 10 attempts than when 10 or more attempts were made without precutting (p=0.02). CONCLUSIONS: Pancreatitis rate was lower when precut was done with <10 attempts than when ≥10 attempts were made without precutting. In experienced hands precut biliary sphincterotomy does not seem to be an independent risk factor for post-ERCP pancreatitis in patients undergoing endoscopic retrograde cholangio-pancreatography for bile duct stones.

OBJECTIVES: Prospective studies have identified a number of patient- and procedure-related independent risk factors for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis, with different conclusions, so various questions are still open. The endoscopist's expertise, case volume, and case mix can all significantly influence the outcome of ERCP procedures, but have been investigated little to date. METHODS: We identified patient- and procedure-related risk factors for post-ERCP pancreatitis and the impact of the endoscopist's experience and the center's case volume, using univariate and multivariate analysis, in a multicenter, prospective study involving low- and high-volume centers, over a 6-month period. RESULTS: A total of 3,635 ERCP procedures were included; 2,838 (78%) ERCPs were performed in the 11 high-volume centers (median 257 each) and 797 in the 10 low-volume centers (median 45 each). Overall, 3,331 ERCPs were carried out by expert operators and 304 by less-skilled operators. There were significantly more grade 3 difficulty procedures in high-volume centers than in low-volume ones (P<0.0001). Post-ERCP pancreatitis occurred in 137 patients (3.8%); the rates did not differ between high- and low-volume centers (3.9% vs. 3.1%) and expert and non-expert operators (3.8% vs. 5.5%). However, in high-volume centers, there were 25% more patients with patient- and procedure-related risk factors, and the pancreatitis rate was one-third higher among non-expert operators. Univariate analysis found a significant association with pancreatitis for history of acute pancreatitis, either non-ERCP- or ERCP-related and recurrent, young age, absence of bile duct stones, and biliary pain among patient-related risk factors, and >10 attempts to cannulate the Vater's papilla, pancreatic duct cannulation, contrast injection of the pancreatic ductal system, pre-cut technique, and pancreatic sphincterotomy, among procedure-related risk factors. Multivariate analysis also showed that a history of post-ERCP pancreatitis, biliary pain, >10 attempts to cannulate the Vater's papilla, main pancreatic duct cannulation, and pre-cut technique were significantly associated with the complication. CONCLUSIONS: A history of pancreatitis among patient-related factors, and multiple attempts at cannulation among procedure-related factors, were associated with the highest rates of post-ERCP pancreatitis. Pre-cut sphincterotomy, although identified as another significant risk factor, appeared safer when done early (fewer than 10 attempts at cannulating), compared with repeated multiple cannulation. The risk of post-ERCP pancreatitis was not associated with the case volume of either the single endoscopist or the center; however, high-volume centers treated a larger proportion of patients at high risk of pancreatitis and did a significantly greater number of difficult procedures.

BACKGROUND: Three previous studies from the same institution have reported that transoral incisionless fundoplication (TIF) with the EsophyX device is effective for creating a continent gastroesophageal valve and for good functional results as measured only by pH-metry in patients with gastroesophageal reflux disease (GERD). The objective of the present study was to evaluate the effect of TIF on symptoms, use of proton pump inhibitors (PPI), esophageal motility, and pH-impedance in patients with symptomatic GERD. METHODS: Twenty consecutive patients were enrolled to complete the GERD-HRQL and GERD-QUAL questionnaires while on and off PPI. They were also examined by upper gastrointestinal (GI) endoscopy to determine Hill grade and Jobe length of the gastroesophageal valve, and to check for hiatal hernia and esophagitis, esophageal manometry, and pH-impedance before and 6 months after TIF. RESULTS: Six months after TIF, the GERD-HRLQ and GERD-QUAL scores off-PPI therapy and the number of total and acid pH-impedance refluxes were significantly reduced (p < 0.05). The PPI had been completely stopped in 55% of the patient and was reduced in 22% of the patients. CONCLUSIONS: At 6-month follow-up, TIF performed using the EsophyX device reduces symptoms and pH-impedance refluxes, allowing interruption or reduction of PPI use in 78% of patients with GERD.

BACKGROUND: Acute pancreatitis is a complication of endoscopic retrograde cholangio-pancreatography. Aim of the study was to compare endoscopic retrograde cholangio-pancreatography-related acute pancreatitis with attacks caused by other factors. METHODS: A series of consecutive patients with non-endoscopic retrograde cholangio-pancreatography-related acute pancreatitis referred to our hospital in 2007-2008 were examined retrospectively, and compared with the same number of patients with post-endoscopic retrograde cholangio-pancreatography acute pancreatitis done in the same institution. Both groups comprised 116 patients and were comparable for mean age, sex, and body mass index. Duration of abdominal pain, pancreatic enzyme elevation, hospital stay, and type of analgesia administered were retrieved. RESULTS: There were no differences between the groups as regards the severity of pancreatitis, mortality rate and hospitalisation, although mortality was double in severe post-endoscopic retrograde cholangio-pancreatography acute pancreatitis. In the mild acute pancreatitis cases, serum amylase fell 50% from the peak in a mean of 46.4h (range 24-72) in group 1 and 38.9h (range 24-72) in group 2 (p<0.001). The peak amylase serum level halved within 48h in 73.6% of cases with non-endoscopic retrograde cholangio-pancreatography-related acute pancreatitis, and in 92% of patients with endoscopic retrograde cholangio-pancreatography-related acute pancreatitis (p<0.001). CONCLUSIONS: Non-endoscopic retrograde cholangio-pancreatography- and endoscopic retrograde cholangio-pancreatography-induced pancreatitis did not differ as regards severity, hospital stay or mortality; in mild pancreatitis, serum amylase halved significantly sooner in post-endoscopic retrograde cholangio-pancreatography cases.
