The high rate of spontaneous migration of small size common bile duct stones may allow a significant reduction in unnecessary ERCP and related complications: results of a retrospective, multicenter study.

INTRODUCTION: Common bile duct stones (CBDS) can spontaneously migrate through the duodenal papilla. In this case, ERCP could be unnecessary and a significant rate of complications could be avoided. In this study, we aim at retrospectively evaluating the rate of spontaneous stone passage in patients with an imaging diagnosis of CBDS and at analysing the factors associated to spontaneous stone migration. METHODS: We conducted a retrospective multi-centre analysis of patients undergoing ERCP for CBDS in a 12-month period. 1016 patients with CBDS were analysed. In all patients CBDS was diagnosed with adequate imaging methods performed prior to ERCP. ERCPs with failed biliary cannulation were excluded. Data regarding patients' characteristics, imaging findings and ERCP procedure were analysed. RESULTS: 1016 patients with CBDS undergoing ERCP were analysed (male sex 43.3%; mean age 69.9 ± 16.5 years). Diagnosis of CBDS was obtained by EUS in 415 patients (40.8%), MR in 343 (33.8%), CT in 220 (21.7%), and US in 38 (3.7%). No stones were found at ERCP in 179 patients (17.6%), in 14 (6.2%) when ERCP was performed within 6 h from imaging study, in 114 (18.5%) between 7 h and 7 days, in 32 (24.6%) between 8 and 29 days, and in 19 (43.2%) after 30 days. The rate of unnecessary ERCP occurred significantly more frequently in patients in whom imaging methods demonstrated either sludge or ≤ 5 mm CBDS (29.9 vs. 8.3%; p < 0.001). DISCUSSION: Spontaneous migration of small CBDS is a frequent event, and ≤ 5 mm size and a delay in ERCP > 7 days represent predictive factors for it. We suggest that CBDS ≤ 5 mm should not undergo immediate removal and this fact would allow reducing the rate of unnecessary ERCP with their related complications. Prospective studies are needed to confirm these results and demonstrate the safety of a conservative management in this setting.

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

Background and study aims COVID-19 has dramatically impacted endoscopy practice because upper endoscopy procedures can be aerosol-generating. Most elective procedures have been rescheduled. Endoscopic retrograde cholangiopancreatography (ERCP) is frequently performed in emergency or urgent settings in which rescheduling is not possible. We evaluated the impact of the COVID-19 pandemic on ERCP in Italy during the SARS-CoV-2 lockdown, in areas with high incidence of COVID-19. Patients and methods We performed a retrospective survey of centers performing ERCP in high COVID-19 prevalence areas in Italy to collect information regarding clinical data from patients undergoing ERCP, staff, case-volume and organization of endoscopy units from March 8, 2020 to April 30, 2020. Results We collected data from 31 centers and 804 patients. All centers adopted a triage and/or screening protocol for SARS-CoV-2 and performed follow-up of patients 2 weeks after the procedure. ERCP case-volume was reduced by 44.1 % compared to the respective 2019 timeframe. Of the 804 patients undergoing ERCP, 22 (2.7 %) were positive for COVID-19. Adverse events occurred at a similar rate to previously published data. Of the patients, endoscopists, and nurses, 1.6 %, 11.7 %, and 4.9 %, respectively, tested positive for SARS-CoV-2 at follow up. Only 38.7 % of centers had access to a negative-pressure room for ERCP. Conclusion The case-volume reduction for ERCP during lockdown was lower than for other gastrointestinal endoscopy procedures. No definitive conclusions can be drawn about the percentage of SARS-CoV-2-positive patients and healthcare workers observed after ERCP. Appropriate triage and screening of patients and adherence to society recommendations are paramount.

Inflammatory bowel disease in a colorectal cancer screening population: Diagnosis and follow-up.

BACKGROUND: Inflammatory bowel disease (IBD) is usually diagnosed in subjects with gastrointestinal symptoms, but may also be asymptomatic and diagnosed incidentally. AIMS: to determine the prevalence of IBD in asymptomatic adults. METHODS: we identified subjects who underwent colonoscopy between 1 September 2013 and 31 August 2019 in a regional colorectal cancer screening program with endoscopic findings suggestive of IBD, and retrieved their clinical, histological and therapeutic information. RESULTS: 5116 subjects underwent colonoscopy, and 4640 persons were considered assessable. Of these, 54 (1.16%) had endoscopic findings suggestive of IBD, including 40 of Crohn's disease (CD) and 14 of ulcerative colitis (UC). A definite diagnosis of IBD was made in 19 patients, for an overall IBD prevalence of 0.41%, with 13 cases of CD (0.28%) and 6 of UC (0.13%). The mean follow-up was 26.8 months after the first colonoscopy. Therapy was started in 5 of 13 CD patients and all UC patients. CONCLUSION: Endoscopic findings suggestive of IBD are not infrequent in an asymptomatic colorectal cancer screening population. Visualization of the terminal ileum is recommended in this setting. A definite diagnosis of IBD was made in about 1 out of 3 subjects with endoscopic lesions. Most IBD patients had a mild form of disease, but some needed biologic therapy.

Infection Control Practices and Outcomes of Endoscopy Units in the Lombardy Region of Italy: A Survey From the Italian Society of Digestive Endoscopy During COVID-19 Spread.

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.

Clinical Characteristics of COVID-19 Patients With Gastrointestinal Symptoms in Northern Italy: A Single-Center Cohort Study.

INTRODUCTION: The most typical presentation of COVID-19 is an acute respiratory syndrome whose most common symptoms include fever, cough, and dyspnea. However, gastrointestinal symptoms, such as diarrhea and nausea/vomiting, are increasingly reported in patients affected by COVID-19. This study aimed to describe the prevalence and time of onset of gastrointestinal symptoms in patients affected by COVID-19 and to find potential associations between gastrointestinal symptoms and clinical outcomes. METHODS: We performed a prospective single-center cohort study, enrolling patients who received diagnosis of COVID-19 at our institution between March 23, 2020, and April 5, 2020. We collected patient demographics and medical history, laboratory data, and clinical outcomes. Furthermore, we used a specifically designed questionnaire, administered to patients at time of diagnosis, to obtain data on the presence and time of onset of fever, typical respiratory symptoms, gastrointestinal symptoms, and other symptoms (fatigue, headache, myalgia/arthralgia, anosmia, ageusia/dysgeusia, sore throat, and ocular symptoms). RESULTS: In our cohort, 138 (69%) of 190 patients showed at least 1 gastrointestinal symptom at diagnosis; if excluding hyporexia/anorexia, 93 patients (48.9%) showed at least 1 gastrointestinal symptom. Gastrointestinal symptoms, in particular diarrhea, were associated with a lower mortality. At multivariate analysis, diarrhea was confirmed as independent predictive factor of lower mortality. DISCUSSION: Gastrointestinal symptoms are very frequent in patients with COVID-19 and may be associated with a better prognosis. These data suggest that, in some patients, the gastrointestinal tract may be more involved than the respiratory system in severe acute respiratory syndrome coronavirus 2 infection, and this could account for the less severe course of disease.

Efficacy of a novel self-assembling peptide hemostatic gel as rescue therapy for refractory acute gastrointestinal bleeding.

BACKGROUND: Acute gastrointestinal bleeding (AGIB) results in significant morbidity and mortality. Topical hemostatic products have been developed for endoscopic use to help in the management of difficult bleeding. Our aim was to demonstrate the ease of use, safety, and efficacy of PuraStat, a novel hemostat, to control AGIB. METHODS: We describe 77 patients (41 men) who were treated for acute upper and lower AGIB in a 2-year period. In 50 patients, bleeding occurred as a complication of a previous endoscopic procedure, predominantly endoscopic mucosal resection (EMR) and endoscopic retrograde cholangiopancreatography (ERCP); however, in the other 27 patients, it derived from peptic ulcers, angiodysplasia, cancers, and surgical anastomoses. Bleeding was spurting in 13 of the 77 patients and oozing in 64. PuraStat was used after the failure of at least two conventional hemostatic methods. RESULTS: A mean of 2.6 conventional hemostatic methods had been attempted prior to the application of PuraStat. PuraStat achieved successful hemostasis in 90.9 % of patients. In 41 patients, once hemostasis was obtained with PuraStat, endoscopists further stabilized hemostasis by using at least one additional method. Recurrence of bleeding was observed in eight patients (10.4 %). In 16 patients with intraprocedural bleeding, it was possible to complete the procedures (14 EMR, 2 ERCP) after PuraStat hemostasis. No adverse events related to PuraStat were recorded. CONCLUSIONS: PuraStat is feasible, safe, and effective in controlling different types of gastrointestinal hemorrhage after failure of conventional hemostatic methods. Its application also does not hinder continuing endotherapy.

Tolerability of Bowel Preparation and Colonoscopy in IBD Patients: Results From a Prospective, Single-Center, Case-Control Study.

Background: Endoscopy plays a fundamental role in the management of patients with inflammatory bowel disease (IBD). The aim of this study was to prospectively evaluate the tolerability and efficacy of bowel preparation and colonoscopy in ulcerative colitis (UC) and Crohn's disease (CD) patients compared to subjects participating in a colorectal cancer population screening program. Methods: Consecutive enrolment of CD and UC patients and screening subjects (SS) undergoing colonoscopy. Bowel preparation was done by split dose of 2 L PEG-ELS + simethicone. We recorded endoscopic, clinical, and demographic features; cleanliness rating using the Boston Bowel Preparation Scale (BBPS); and sedation doses. Bowel-preparation tolerability, discomfort, and pain during colonoscopy were assessed using a Visual Analogue Scale from 0 to 100 mm. Results: Sixty-three UC (mean age 49.9 ± 14.9 years), 63 CD (mean age 44.0 ± 14.0 years), and 63 SS (mean age 59.9 ± 6.3 years) patients were enrolled. Bowel preparation was similarly tolerated in UC, CD, and SS (P = 0.397). A complete colonoscopy was similarly performed in UC (59/63, 93.7%), CD (58/63, 92.1%), and SS (60/63, 95.2%) (P = 0.364). The BBPS did not show significant differences between UC (6.2 ± 1.6), CD (6.1 ± 1.3), and SS (6.2 ± 1.4) (P = 0.824). The need to increase sedation doses was significantly higher in CD (24/63, 38.1%) and UC (16/63, 25.4%) than in SS (4/63, 6.3%) (P < 0.0001). Conclusions: Bowel preparation is equally tolerated and efficacious in IBD patients and in healthy SS. In IBD, higher sedation doses are needed to guarantee an equally tolerated colonoscopy.

Intra-procedural and delayed bleeding after resection of large colorectal lesions: The SCALP study.

Background and aim: The safety of endoscopic resection of large colorectal lesions (LCLs) (≥20 mm) is clinically relevant. The aim of the present study was to assess the rate of post-resection adverse events (AEs) in a real-life setting. Patients and methods: In a prospective, multicentre, observational study, data from consecutive resections of LCLs over a 6-month period were collected in 24 centres. Patients were followed up at 15 days from resection for AEs. The primary endpoint was intra-procedural bleeding according to lesion morphology. Secondary endpoints were delayed bleeding and perforation. Patient and polyp characteristics, and polypectomy techniques were analysed with respect to the bleeding events. Results: In total, 1504 patients (female/male: 633/871, mean age, 66.1) with 1648 LCLs (29.1% pedunculated and 70.9% non-pedunculated lesions) were included. Overall, 168 (11.2%) patients had post-resection bleeding (8.5 and 2.0% immediate and delayed, respectively), while 15 (1.0%) cases of perforation occurred. Independent predictors of immediate bleeding for pedunculated lesions were bleeding prophylaxis (odds ratio (OR) 0.28, 95% confidence interval (CI) 0.13-0.62), simple polypectomy (versus endoscopic mucosal resection, OR 0.38, 95% CI 0.17-0.88) and inpatient setting (OR 2.21, 95% CI 1.07-5.08), while bleeding prophylaxis (OR 0.37, 95% CI 0.30-0.98), academic setting (OR 0.27, 95% CI 0.12-0.54) and size (OR 1.03, 95% CI 1.00-1.05) were predictors for those non-pedunculated. Indication for colonoscopy (screening versus diagnostic (OR 0.33, 95% CI 0.12-0.86)), antithrombotic therapy (OR 3.12, 95% CI 1.54-6.39) and size (OR 2.34, 95% CI 1.12-4.87) independently predicted delayed bleeding. Conclusions: A low rate of post-resection AEs was observed in a real-life setting, reassuring as to the safety of endoscopic resection of ≥2 cm colorectal lesions. Bleeding prophylaxis reduced the intra-procedural bleeding risk, while antithrombotic therapy increased delayed bleeding.CLINICALTRIAL: (NCT02694120).

Efficacy of withdrawal time monitoring in adenoma detection with or without the aid of a full-spectrum scope.

Background and study aims Withdrawal time (WT) monitoring and full-spectrum endoscopy (FUSE) have been suggested to increase adenoma detection rate (ADR) due to more accurate evaluation of the hidden areas of the colon. We aimed to evaluate the efficacy of WT monitoring and FUSE on ADR. Patients and methods This was a prospective observational study involving consecutive outpatients, aged 18 to 85 years, undergoing colonoscopy with unselected indications. In phase 1, endoscopists performed 660 colonoscopies either with standard forward-viewing endoscope (SFVE) (n = 330) or with FUSE (n = 330). In this phase, WTs were measured without endoscopist awareness of being monitored. In phase 2, endoscopists were informed of being monitored and performed additional 660 colonoscopies either with SFVE (n = 330) or with FUSE (n = 330). Results WT was lower in phase 1 compared to phase 2 (SFVE: 269 ±â€Š83 vs. 386 ±â€Š60 sec, P  < 0.001; FUSE: 289 ±â€Š97 vs. 403 ±â€Š65 sec, P  < 0.001). Use of FUSE increased ADR both in phase 1 (33.0 % vs. 27.3 %, P  = 0.127) and in phase 2 (41.8 % vs. 33.6 %, P  = 0.037). When endoscopists were aware of being monitored, ADR was higher in SFVE (33.6 % vs. 27.3 %; P  = 0.090) and FUSE arms (41.8 % vs. 33.0 %; P  = 0.024). Improvement in detection of proximal adenomas was associated with WT monitoring [OR 1.577 (95 % C. I. 1.158 - 2.148); P  = 0.004], whereas detection of distal adenomas was associated with use of FUSE [OR 1.320 (95 % C. I. 1.022 - 1.705); P  = 0.037]. Conclusions Unmonitored endoscopists have suboptimal WT, which increases when they are monitored. WT monitoring and use of FUSE are two reliable and alternative strategies to increase ADR.

Complications and early mortality in percutaneous endoscopic gastrostomy placement in lombardy: A multicenter prospective cohort study.

BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) is the most common endoscopic procedure used to provide nutritional support. AIM: To prospectively evaluate the mortality and complication incidences after PEG insertion or replacement. METHODS: All patients who underwent PEG insertion or replacement were included. Details on patient characteristics, ongoing therapies, comorbidities, and indication for PEG placement/replacement were collected, along with informed consent form signatures. Early and late (30-day) complications and mortality were assessed. RESULTS: 950 patients (47.1% male) were enrolled in 25 centers in Lombardy, a region of Northern Italy. Patient mean age was 73 years. 69.5% of patients had ASA status 3 or 4. First PEG placement was performed in 594 patients. Complication and mortality incidences were 4.8% and 5.2%, respectively. The most frequent complication was infection (50%), followed by bleeding (32.1%), tube dislodgment (14.3%), and buried bumper syndrome (3.6%). At multivariable analysis, age (OR 1.08 per 1-year increase, 95% CI, 1.0-1.16, p = 0.010) and BMI (OR 0.86 per 1-point increase, 95% CI, 0.77-0.96, p = 0.014) were factors associated with mortality. PEG replacement was carried out in 356 patients. Thirty-day mortality was 1.8%, while complications occurred in 1.7% of patients. CONCLUSIONS: Our data confirm that PEG placement is a safe procedure. Mortality was not related to the procedure itself, confirming that careful patient selection is warranted.

Comparison of asymmetric (low morning-dose) and standard split-dose regimen of PEG plus bisacodyl for bowel preparation: A randomized controlled trial.

BACKGROUND: Reducing the morning dose of PEG solution may be a reliable strategy to improve the patient compliance of split-dose regimens without affecting efficacy of bowel cleansing. AIMS: to compare the efficacy for bowel cleansing of an asymmetric split-dose regimen (25% of the dose on the day of colonoscopy and 75% on the day before) with the standard split-dose regimen. METHODS: Outpatients were enrolled in a randomized, single-blind, non-inferiority clinical trial. All subjects received a split-dose preparation with a 2L PEG-citrate-simethicone plus Bisacodyl. Patients were randomly assigned to: group A, asymmetric split-dose regimen; group B, symmetric split-dose regimen. Primary endpoint was the proportion of adequate bowel cleansing. RESULTS: Split-dose was taken by 81 and 80 patients in group A and B. Adequate bowel cleansing was achieved in 92.6% and 92.5% patients in group A and B (p = 1.000). No differences were observed regarding Boston Bowel Preparation Scale total score, adenoma detection rate and scores of each colon segment. CONCLUSIONS: The reduction of morning dose of PEG in a split-dose regimen is not inferior to the standard split-dose regimen in achieving an adequate bowel cleansing. However, further studies are needed to evaluate whether asymmetric preparation is associated to a higher tolerability compared to symmetric split-dose regimen. (NCT03146052).

Diagnostic yield and miss rate of EndoRings in an organized colorectal cancer screening program: the SMART (Study Methodology for ADR-Related Technology) trial.

BACKGROUND AND AIMS: The EndoRings add-on has been claimed to improve adenoma detection at colonoscopy, but available data are inconsistent. When testing a new technology, parallel and crossover methodologies measure different outcomes, leaving uncertainty about their correspondence. The aims of this study were to compare the diagnostic yield and miss rate of the EndoRings for colorectal neoplasia. METHODS: Consecutive patients undergoing colonoscopy after a positive fecal immunochemical test (FIT) within an organized screening program in 7 Italian centers were randomized between a parallel (EndoRings or standard) or a crossover (EndoRings/standard or standard/EndoRings) methodology. Outcomes measures were the adenoma detection rate (ADR) and advanced adenoma detection rate (AADR) in the parallel arms and the miss rate of adenomas in the crossover arms. RESULTS: Of 958 eligible patients, 927 (317 EndoRings; 317 standard; 142 EndoRings/standard; 151 standard/Endo-Rings) were included in the final analysis. In the parallel arms (mean ADR, 51.3%; mean AADR, 25.4%), no difference between standard and EndoRings was found for both ADR (relative risk [RR], 1.10; 95% confidence interval [CI], 0.95-1.28) and AADR (RR, 1.16; 95% CI, 0.88-1.51), as well as for the mean number of adenomas and advanced adenomas per patient (EndoRings, 1.9 ± 1.3 and 1.0 ± 1.2; standard, 2.1 ± 1.5 and 1.0 ± 1.2; P = not significant for both comparisons). In the crossover arms, no difference in the miss rate for adenomas between EndoRings and standard was found at per polyp (RR, 1.43; 95% CI, 0.97-2.10) or per-patient analysis (24% vs 26%; P = .76). CONCLUSIONS: No statistically significant difference in diagnostic yield and miss rate between EndoRings and standard colonoscopy was detected in patients with a positive FIT result. A clinically relevant correspondence between miss and detection rates was shown, supporting a cause-effect relationship. (ISRCTN registry: ISRCTN10357435.).

Endoscopic papillary large balloon dilation in patients with large biliary stones and periampullary diverticula: Results of a multicentric series.

INTRODUCTION: Stone extraction represents the most frequent indication for endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic papillary large balloon dilation (EPLBD) is a recent introduced approach consisting of an endoscopic papillary large balloon dilation following limited endoscopic sphyncterotomy (ES), which has been proven to be safe and effective for extraction of large common bile duct (CBD) stones. Peri-ampullary diverticula (PAD) are described in 10-20% of patients undergoing ERCP. Aim of our study is to evaluate efficacy and safety of EPLBD for the extraction of large biliary stones in patients with PAD. METHODS: The prospectively collected endoscopy databases of 4 Italian ERCP high-volume centers were reviewed retrospectively, and all consecutive patients with an instrumental diagnosis of large biliary stones and PAD, between September 2014 and October 2016, were included in this study. RESULTS: Eighty-one patients (36 males, median age 75 years) were treated between September 2014 and October 2016. Deep biliary cannulation was reached in 78/80 patients. Successful extraction was achieved in 74/78 patients at the first attempt. AEs occurred in 8 patients (1 severe). Younger age, stone size and incomplete stone extraction were significantly associated with AEs. CONCLUSIONS: EPLBD is an effective and safe technique in patients with PAD and large biliary stones, which avoids the need of other techniques, thereby reducing the risks of adverse events.

Aspecific ileitis: Crohn's disease or not Crohn's disease? A prospective study.

PURPOSE: It is not clear whether aspecific ileitis may represent an early manifestation or a milder variant of Crohn's disease or not. The aim of this study was to evaluate the clinical outcomes of aspecific ileitis. METHODS: Subjects with at least one of the following signs at retrograde ileoscopy: erythema, nodularity, aftae, erosions, and ulcers were considered. They should not have had defined gastrointestinal disease, biochemical signs of inflammation, use of drugs, celiac disease, and intestinal infectious disease. RESULTS: We enrolled 51 subjects (22 men), mean age (± SD) at colonoscopy of 41.1 ± 13.1 years. Indications to colonoscopy were overt or occult intestinal bleeding (18), diarrhoea (15), systemic signs (10), IBS-like symptoms (5), other (3). Ileal lesions were ulcers (9), erosions (26), aftae (10), nodularity (3), and erythema (3). At histological evaluation aspecific findings were observed. Forty-four out of 51 (86.3%) subjects underwent further investigations of small bowel. Second colonoscopy was performed in 31 (60.8%) persisting symptomatic subjects: ileitis was confirmed in 14 (46.6%). Ten out of 51 (19.6%) were eventually diagnosed as affected by Crohn's disease. CONCLUSIONS: A substantial proportion of subjects with endoscopic and histological findings of aspecific ileitis is eventually diagnosed as affected by Crohn's disease. In these subjects, a strict follow-up is strongly recommended.

Granulocyte-Monocyte Apheresis in Steroid-Dependent, Azathioprine-Intolerant/Resistant Moderate Ulcerative Colitis: A Prospective Multicenter Study.

BACKGROUND: Granulocyte-monocyte apheresis has been proposed for the treatment of ulcerative colitis, although it is limited by costs and variability of results. AIM: To assess effectiveness of granulocyte-monocyte apheresis in patients with steroid-dependent, azathioprine-intolerant/resistant moderate ulcerative colitis. METHODS: Consecutive patients fulfilling inclusion criteria were prospectively enrolled, treated by apheresis, and followed up for 12 months. The primary end point of the study was steroid-free clinical remission at 12 months, with no need for biologic therapy or surgery. RESULTS: From January to December 2013, 33 patients were enrolled. After one year of follow-up, 12 (36%) patients had clinical remission, were steroid-free, and had no need for biological therapy or surgery; 3 (9%) cases showed a clinical response (but not clinical remission). Moreover, 12 (36%) patients required biologic therapy, 4 (12%) underwent colectomy, and in the other 2 (6%) a reduction, but not withdrawal, of steroid dose was achieved. CONCLUSIONS: Our study shows that a standard course of granulocyte-monocyte apheresis is associated with a 36% steroid-free clinical remission in patients with steroid-dependent, azathioprine-intolerant or resistant moderate ulcerative colitis. Apheresis might represent an alternative to biologic therapy or surgery in this specific subgroup of patients. This trial is registered with Clinicaltrial.gov NCT03189888.

Early and delayed complications of polypectomy in a community setting: The SPoC prospective multicentre trial.

BACKGROUND: Colonoscopic polypectomy is effective in reducing the incidence of and mortality from colorectal cancer, but is not complication-free. AIMS: To evaluate the incidence of early and delayed polypectomy complications and factors associated with their occurrence in a community setting. METHODS: Web-database collection of patients' and polyp's features in consecutive colonic polypectomies during a 3-month period in 18 endoscopy centres. RESULTS: Data on 5178 polypectomies in 2692 patients (54.3% males, mean age 59 years) were collected. The majority of the polyps were <10mm (83.5%). Antithrombotic agents were taken by 22.7% of patients, 57.3% of which withheld them before the procedure. Overall, 5 patients experienced perforations (0.2%) and 114 had bleeding (4.2%); the overall complication rate was 4.4%. Early complications were observed in 87 (3.2%); delayed complications (all major bleedings) occurred in 32 (1.2%). At multivariate analysis polyp size (size >10mm: OR 4.35, 95% CI 5.53-7.48) and, inversely, right-sided location (OR 0.58, 95% CI 0.36-0.94) were correlated with bleeding events. The use of antithrombotics was associated with 5-fold increased risk of delayed bleeding. CONCLUSIONS: In the community setting, polypectomy was associated with a 1.4% risk of major complications. Polyp size and, inversely, right-sided location were associated with early bleeding; the use of antithrombotics increased the risk of delayed events.

The morphological and immunohistochemical spectrum of gastric biopsies of patients with absorptive hypercalciuria.

OBJECTIVE: Idiopathic hypercalciuria is characterised by renal stone formation and vertebral osteoporosis. The syndrome displays high clinical variability with patients almost equally distributed between fasting or renal type (prevalent calcium loss) and absorptive type (prevalent increase of intestinal absorption). Absorptive hypercalciuria (AH) is characterised by hypersensitivity of calcium-sensing receptors of antral G cells with normal fasting gastrinaemia and meal hypergastrinaemia. To the best of our knowledge, no study has been published about the morphological aspects of gastric biopsies of patients with AH and the immunohistochemical findings of gastrin-producing G cells. So we studied morphologically and immunohistochemically a group of 38 patients with AH, describing their gastric findings and associated lesion. DESIGN: All 38 patients had a clinical-laboratory diagnosis of AH with normal fasting hypergastrinaemia and an abnormal rise of gastrinaemia after a standardised meal test. Their 38 antral and 27 body-fundus biopsies, and 5 normal antral and body controls, were stained with H&E, Giemsa stain, polyclonal antiserum anti-Gastrin and a monoclonal antibody anti-Chromogranin A. RESULTS: Antral biopsies of all 38 patients showed a simple (15) or linear (23) hyperplasia of G cells, whereas only 2 of 27 body biopsies showed a nodular hyperplasia of endocrine cells. In five patients with AH, we found an association with fundic gland polyps (FGPs). CONCLUSIONS: We found in all of the patients with AH a correlation between meal hypergastrinaemia and morphological antral G-cell hyperplasia. Moreover, in five patients, AH was associated with FGPs. We know from literature data that FGPs' development in Zollinger-Ellison syndrome is statistically associated with hypergastrinaemia. From our present data, we suggest that even in AH the stimulated hypergastrinaemia may have a role in polyp development.
