RESUMO
Endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) are both crucial for the endoscopic management of biliopancreatic diseases: the combination of their diagnostic and therapeutic potential is useful in many clinical scenarios, such as indeterminate biliary stenosis, biliary stones, chronic pancreatitis and biliary and pancreatic malignancies. This natural and evident convergence between EUS and ERCP, which by 2006 we were calling the "Endoscopic ultrasonography retrograde colangiopancreatography (EURCP) concept", has become a hot topic in the last years, together with the implementation of the therapeutic possibilities of EUS (from EUS-guided necrosectomy to gastro-entero anastomoses) and with the return of ERCP to its original diagnostic purpose thanks to ancillary techniques (extraductal ultrasound (EDUS), intraductal ultrasound (IDUS), cholangiopancreatoscopy with biopsies and probe-based confocal laser endomicroscopy (pCLE)). In this literary review, we retraced the recent history of EUS and ERCP, reported examples of the clinical applicability of the EURCP concept and explored the option of performing the two procedures in only one endoscopic session, with its positive implications for the patient, the endoscopist and the health care system. In the last few years, we also evaluated the possibility of combining EUS and ERCP into a single endoscopic instrument in a single step, but certain obstacles surrounding this approach remain.
RESUMO
BACKGROUND AND AIMS: Telemonitoring is increasingly used in the management of IBD patients. We investigated the agreement between patients and physicians on scores of disease activity and burden. METHODS: Consecutive outpatients at one IBD clinic were recruited between February and December 2021. Enrolled patients completed a questionnaire for disease activity (Harvey-Bradshaw Index [HBI] for Crohn's disease or Simple Clinical Colitis Activity Index [SCCAI] for ulcerative colitis) and a test of disease burden (Pictorial Representation of Illness and Self Measure [PRISM]). They did the tests within 5 days of an outpatient visit, working independently on IBD Tool, a new web-based telemonitoring application. Concomitantly, the senior and junior physicians who examined them completed the same tests. The agreement was tested for every pair of scores. RESULTS: Five hundred and sixty patients (289 Crohn's disease; 271 ulcerative colitis) completed disease questionnaires on IBD Tool (in total, 742 times). By Spearman's correlation, the agreement was substantial both for HBI (rho 0.685-0.837) and SCCAI (rho 0.694-0.888) for comparisons between patients, junior and senior physicians. The agreement was moderate-to-substantial for PRISM (rho 0.406-0.725) for the same comparisons. The correlation between disease activity (HBI/SCCAI) and PRISM scores was substantial for senior (rho 0.757-0.788) or junior (rho 0.746-0.753) physicians and moderate for patients (rho 0.458-0.486). The median PRISM score difference was 2.3-1.6 points lower between patients and senior-junior physicians. CONCLUSION: Agreement between IBD patients and physicians was substantial for disease activity and moderate for disease impact. The inclusion of disease burden scoring in telemonitoring platforms provides important information for the management of IBD patients.Study highlightsWhat IS knownâ¢Continuous response to treatments and patient-reported outcomes became an essential goal for IBD patient management.â¢The use of tele-monitoring and eHealth technologies allows for regular disease assessments and for managing more efficiently IBD patients; disease questionnaires and tests are key to support eHealth tools.What is new hereâ¢Agreement between IBD patients and physicians was substantial for disease activity and moderate for disease burden, while agreement among junior and senior physicians was substantial for both.â¢PRISM performs as well for ulcerative colitis as for Crohn's patients.â¢The inclusion of disease burden tests might add to eHealth platforms valuable information, complemental to disease activity questionnaires.

Emergency subtotal colectomy is the standard treatment for acute severe ulcerative colitis (ASUC) unresponsive to medical treatment. No guidelines are available about surgical technique. The aim of the current survey was to identify the attitudes of Inflammatory Bowel Disease (IBD) surgeons concerning colectomy in patients with ASUC by means of a nationwide survey, with specific focus on intraoperative technical details. A survey was developed with focus on number of procedures performed, approach to vascular ligation, technique of bowel dissection, treatment of the omentum and of the rectal stump. Twenty Centres completed the survey. Seventy percent of responders started the colectomy laparoscopically. No significant differences were observed about vessels and mesocolic dissection as well as on the choice of the starting colon side and management of the omentum. Ileocolic vessels were ligated distally by 70% and at the origin by 30% and those who transect mesenteric vessels distally are significatively more likely to perform the dissection from lateral to medial and to cut the middle colic vessels distally and 100% of the ones linking left vessels at mesenteric axis transect middle colic vessels at the origin. No differences were observed in the treatment of rectal stump; however, all surgeons who performed a transrectal drainage (45%) left the rectal stump intraperitoneal (p < 0.05). No consensus exists about the technique of dissection, vascular ligation, treatment of the omentum and management of rectal stump. Further studies are needed to evaluate the impact of the different surgical techniques on patients' outcomes.

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 44.1â% compared to the respective 2019 timeframe. Of the 804 patients undergoing ERCP, 22 (2.7â%) were positive for COVID-19.âAdverse events occurred at a similar rate to previously published data. Of the patients, endoscopists, and nurses, 1.6â%, 11.7â%, and 4.9â%, respectively, tested positive for SARS-CoV-2âat follow up.âOnly 38.7â% 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.
RESUMO
BACKGROUND: The SARS-CoV-2 outbreak early in 2020 overwhelmed the Italian national health system, and hospitals were considered places at high risk of spreading the infection. We explored specific antibody seroprevalence of all employees at a single hospital in the epicentre of the outbreak, to identify areas of risk in nosocomial setting and to evaluate the usefulness of antibody testing. AIMS: Aim of this study was to explore SARS-CoV-2 seroprevalence in a single hospital workers cohort. METHODS: All hospital workers were invited to fill in a questionnaire and undergo a blood test for SARS-CoV-2 IgG, using two commercial tests (DiaSorin and Abbott). Seropositivity was determined overall and according to demographic and occupations characteristics, for both tests singly and combined. RESULTS: The study enrolled 1562 hospital workers (95% of the eligible population). Overall, 153 (9.8%) participants were positive for SARS-CoV-2 IgG on DiaSorin test, and 150 (9.6%) were positive on Abbott test; both tests were positive in 123 (7.9%) cases and at least one was positive in 180 (11.5%) cases. Factors associated with SARS-CoV-2 seropositivity included: being a smoker, working in emergency or medicine departments, being a healthcare practitioner, self-reporting a relative with COVID-19 or symptoms suggestive of COVID-19, and having undergone a nasopharyngeal swab test. The tests were accurate in discriminating infected cases, with an area under the receiver operating characteristic curve of 0.867 using manufacturer-suggested cut-offs and 0.929 using optimised cut-offs. For discriminating symptomatic subjects, this value was 0.915 using optimised cut-offs. CONCLUSIONS: Seroprevalence for SARS-CoV-2 in this population of hospital workers was overall about 10%, with an excess prevalence in roles and departments associated with contacts with COVID-19 patients.

Intestinal involvement in ulcerative colitis is generally limited to the colon and rectum. We describe a life-threatening case of ulcerative enteritis occurring after colectomy. Other 53 similar cases are reported in the literature. The aim of this narrative review was to focus on ulcerative enteritis characteristics and diagnostic workup. A 25-year-old boy affected by ulcerative colitis underwent a total colectomy in an urgent setting for septic shock. Postoperative course was characterized by elevated ileostomy output, raised up to 10 L/day. Critical clinical conditions required resuscitation therapy. After exclusion of surgical complications, intestinal infections, and histologic specimen revision, the patient underwent endoscopic examination. Ileal biopsies revealed ileal localization of ulcerative colitis. Steroid treatment was finally effective. After literature revision, we classified all cases of ulcerative enteritis in three groups, according to intestinal involvement pattern and timing of clinical manifestation after operation. Out of 54 cases, 18 occurred within 1 month since colectomy (early ileitis), 10 later on (late ileitis) and 26 do not involve ileus (nonileitis). Clinical manifestation is generally severe in the first group and mild and chronic in the others. Differential diagnoses of ulcerative enteritis are represented by infectious, immunological, toxic, and ischemic disorders. Those conditions excluded, ulcerative enteritis can be easily detected by endoscopic biopsies and treated with immunosuppressive agents. Long term surveillance seems important since recurrences are described. In conclusion, clinicians should suspect ulcerative enteritis in all patients with previous colectomy history that develop unexplained gastrointestinal syndromes, in order to avoid therapeutic delay.

BACKGROUND AND AIMS: Post-surgical recurrence of Crohn's disease (CD) after ileocolonic resection is common. Early identification of features associated with recurrence is a standard procedure of postoperative management, but the prognostic role of such features when detected at later time points is unclear. We compared the predictivity for Crohn's disease recurrence of common clinical-instrumental variables when assessed early (<12 months) or late (>36 months) after surgery. METHODS: This retrospective study considered CD patients who had ileocolonic resection and were followed for a median of 7.6 years. Clinical characteristics, post-surgical therapy, endoscopy recurrence (Rutgeerts' score ≥i2) and ultrasound features were compared between subgroups who had a early or late post-surgical assessment. Univariate and multivariate analyses were done to identify variables associated with recurrence (clinical and surgical). RESULTS: Of 201 patients, 70 (32%) had a early and 39 (19%) had a late post-surgical assessment. The Early and Late subgroups had similar clinical characteristics. Overall, clinical relapse was observed in 131 patients (66%), surgical relapse in 31 (16%), endoscopic recurrence in 149 (75%) and ultrasonographic recurrence in 132 (66%), without significant differences in frequencies between subgroups. By Cox proportional hazard regression, endoscopic recurrence was a significant predictor of clinical recurrence overall (HR=2.31, Pâ¯=â¯0.002) and in the Early (HR=3.85, Pâ¯=â¯0.002) but not Late subgroup. DISCUSSION: The most informative postoperative CD assessment is the one done within the first year of surgery. Later endoscopic evaluations have no prognostic value and should be done only for clinical needs or for research purposes.

BACKGROUND: Enhanced Recovery After Surgery (ERAS) offers many benefits for patients with colorectal cancer. However, its application to patients with Crohn's disease (CD) is questioned. AIM: The aim of this propensity-matched study was to validate the results of ERAS protocol on CD patients. METHODS: Patients undergoing ileocolic resection for primary or relapsed CD from 2007 to 2018 were retrospectively analyzed and propensity-matched into two equal groups (ERAS vs standard of care). Demographic characteristics, length of stay, bowel function, oral intake, and perioperative morbidity were analyzed. RESULTS: Ninety four out of 299 patients were selected for analysis. No significant difference was observed for age, gender, American Society of Anesthesiologists score, body mass index, previous surgery and therapy, operative time and laparoscopy. The median length of stay in ERAS and non-ERAS groups was 6 and 8 days (pâ¯<â¯0.001). Median postoperative days of first bowel movement and solid oral intake were day 1 and day 2 pâ¯<â¯0,001, and day 2 and day 4.5 pâ¯<â¯0,001 in ERAS and non-ERAS group, respectively. No statistically differences in other postoperative outcomes were shown. CONCLUSIONS: ERAS implementation showed decreased length of stay, faster bowel function restoration and earlier solid oral intake in patients who underwent laparoscopic or open ileocolic resection for primary or relapsing CD.

BACKGROUND: Inflammatory bowel disease is treated with anti-TNF agents such as infliximab and its biosimilars, but use of biosimilars is limited due to perceived risks of adverse events. AIM: To explore safety and effectiveness of switching from the infliximab originator to a first biosimilar. PATIENTS AND METHODS: Clinical and biological outcomes were compared between 53 patients who switched from the infliximab originator to the biosimilar CT-P13 (Switched group) and 13 patients treated with CT-P13 from the beginning (Naïve group). Infliximab trough levels and antidrug antibodies were measured. RESULTS: At enrolment, patients in the Switched group had a longer median duration of infliximab treatment than Naïve (4.0 vs. 0.6 years, pâ¯<â¯0.0001) but similar proportions of patients were in remission (77% and 62%, respectively). Infliximab discontinuation due to adverse events or loss of efficacy was less common in the Switched (26%) than Naïve group (62%, pâ¯=â¯0.017). Variables independently associated with time to discontinuation were disease activity (pâ¯<â¯0.0001) and immunomodulating treatment (pâ¯=â¯0.019) at enrolment. Trough levels and antidrug antibodies were similar between groups during observation. CONCLUSION: This study confirms that switching from infliximab originator to a first biosimilar is safe and effective. Patients at highest risk of losing treatment efficacy are those with active disease, irrespective of the therapeutic switch.

Percutaneous ultrasonography (perc-US) and magnetic resonance enterography (e-MR) are the present standards for staging patients with Crohn's disease (CD). However, intraoperative data still have some discrepancies with preoperative ones. The contribution of intraoperative ultrasonography (IOUS) has never been evaluated. Sixty-five consecutive patients scheduled for ileal/colonic resection for CD between 2010 and 2014 were prospectively enrolled. All patients had perc-US, e-MR and IOUS. Data from different imaging modalities were compared. The reference standard was the final pathology. Surgery was scheduled because of intestinal obstruction (n = 31 patients), inflammatory mass (n = 21), fistula (n = 10), or abdominal pain/sepsis (n = 3). Fourteen (21.5%) patients had a major discrepancy between preoperative and intraoperative data that required a modification of the surgical planning (five additional ileal lesions, three unknown ileo-sigmoid fistulas, and six not confirmed CD sites). IOUS correctly staged CD in all but one patients (missed ileo-colonic fistula). Pathology data differed from Perc-US data in 13 (20%) patients, from e-MR data in 14 (21.5%), and from IOUS data in one (1.5%). The sensitivity of Perc-US, e-MR and IOUS was: for the identification of CD sites 84.2%, 86.1%, and 100%; for the identification of stenoses 86.8%, 86.8%, and 100%; for the identification of fistulas 75.0%, 81.3%, and 93.8%, respectively. IOUS contributed to the surgical planning in 8 (12.3%) patients. IOUS is a safe, feasible and easy-to-perform procedure that optimizes staging of CD and, in some patients, helps to better define the treatment strategy. It could be helpful to face complex disease presentations on the basis of objective and reproducible data.

Perivascular epithelioid cell tumors (PEComas) are rare mesenchymal tumors that can affect any part of the body. They can be sporadic or arise in the setting of tuberous sclerosis (TSC). In this article, we report a series of three hepatic and two pancreatic PEComas diagnosed preoperatively with ultrasound-guided fine needle aspiration (FNA). All patients were female (age range 28-70), had no personal history of TSC and presented with a single, localized painless mass. Rapid on-site evaluation (ROSE) of cytologic samples was performed for all cases to evaluate for cellular content and adequacy of specimens. Direct smears and cell block preparations revealed a proliferation of medium to large polygonal epithelioid cells, with abundant eosinophilic and vacuolated cytoplasm, arranged in sheets and nests. On immunohistochemistry (IHC), neoplastic cells showed co-expression of melanocytic and smooth muscle markers and a diagnosis of PEComa was rendered. PEComas of the pancreas and liver are rare neoplasms, but should always be considered when examining "clear cell" neoplasms, especially in young female patients. If good quality cytologic samples are obtained by FNA, a correct diagnosis can be achieved with the help of IHC. This is of particular importance in order to plan adequate surgical strategy and to avoid overtreatment.

Helicobacter pylori (H. pylori) is a Gram-negative bacterium, usually acquired during childhood, whose natural habitat is the gastric lumen. H. pylori is accepted as the most important cause of gastritis and peptic ulcer in humans. Nevertheless, its important role in the pathogenesis of gastric cancer as well as in several extra-gastroduodenal diseases has been confirmed. The aim of this work is to discuss, for the first time in a single article, all publications concerning H. pylori infection arising from Piedmont region, Italy, where in 1893 Giulio Bizzozero was the first who observed and described spiral organisms in the stomach of animal models. A systematic review of all publications on the management of H. pylori in adults in Piedmont, based on a PubMed and a Scopus research from 1965 to 2017 was performed. The discussed aspects are the epidemiology, the study on gastric and extragastric diseases related to H. pylori, the diagnostic methods, the treatment of H. pylori infection, and the possibility of reinfection. In conclusions, with almost 70 publications, Piedmont has proudly maintained the tradition of the father of the H. pylori.

Basal plasmacytosis is an early-onset and highly predictive feature of inflammatory bowel disease (IBD), but may have several restrictions in routine histology. Considering evidences about cooperation between eosinophils and plasma cells in IBD pathogenesis, we investigated immunostain of these two cells as a marker of disease. 343 samplings from 83 patients (52 IBD, 31 non-IBD colitis) were evaluated. The sections were stained with monoclonal antibodies against plasma cells (CD138 and MUM1), and eosinophils (CD193). Eosinophilia-associated basal plasmacytosis (EBP) was related with the histologic diagnosis of IBD (90.3% IBD and 35.4% non-IBD colitides, p < 0.005, sensitivity 90.4%). A strong relation was detected between the occurrence of EBP and (i) the achieving of a complete endoscopic mapping; (ii) the presence of other characteristic lesions of IBD in single segmental sampling, although EBP was evident in more than 40% of samples without other IBD-related lesions. EBP is a sensitive histologic feature of IBD, especially at the first endoscopic sampling, even in the absence of the other characteristic histologic lesions, and may help in formulating a more precise diagnosis in this setting.

BACKGROUND: Treatment with infliximab is a common option for inflammatory bowel disease (IBD) patients. Therapeutic drug monitoring could improve treatment management. AIMS: To test inter-test reliability of two commercially available diagnostic kits for infliximab trough levels and infliximab antibodies, and their association with treatment outcomes. METHODS: 86 IBD outpatients on infliximab maintenance treatment were enrolled in a prospective cross-sectional study, 115 samples were available for inter-test reliability. RESULTS: Inter-test agreement was good both for trough levels (concordance correlation coefficient 0.78, weighted κ 0.60, Sperman's ρ 0.937) and for infliximab antibodies (weighted κ 0.79) measurement, when comparing Promonitor and ImmunDiagnostik kits. According to manufacturers' cut-off values, trough levels were classified as undetectable (17%), low (21%) or in range (63%). The only significant associations were: mucosal healing (p=0.026; OR 6.50), infliximab antibody status (p=0.0015; OR 0.031) and adverse events (p=0.009; OR 0.115). Higher trough levels were observed among patients on concomitant steroid/immunosuppressive therapy and among patients with dose-intensification. Infliximab antibodies were significantly associated to treatment-related adverse events (p=0.0003, OR 30.42), and to lower trough levels, but not to other clinical variables. CONCLUSION: The two tests performed equally well. Infliximab antibodies were associated to adverse events, while trough levels were not associated to treatment outcomes.

The difficulties involved in detecting and enumerating Mycobacterium avium subsp. paratuberculosis (MAP) as a pathogen potentially involved in Crohn's disease (CD) are well known. This study aimed to improve this situation through the application of multiple laboratory diagnostic tests to detect and isolate this bacterium from different specimens collected from CD-patients and non-CD subjects as controls. A total of 120 samples (terminal ileum and colon biopsies, blood and stool) were obtained from 19 CD-patients and from 11 individuals who did not have a clinicopathological diagnosis of CD (non-CD controls) attending for ileocolonoscopy. All samples were processed by staining techniques, culture on both solid and liquid media, and Insertion Sequence 900/F57 real-time PCR. The MAP frequency in CD-patients was found in a significantly greater proportion than in non-CD subjects; the most positive samples were biopsies from CD-patients tested by real-time PCR. MAP detection in biopsies, and in the other samples, by applying multiple and validated laboratory diagnostic tests, could be a marker of active infection, supporting MAP involvement in CD.

BACKGROUND: The diagnosis of inflammatory bowel disease can be challenging and requires the efforts of a multidisciplinary team. We performed a retrospective analysis with the aim of evaluating the adequacy of the prerequisites for arriving at an accurate histological diagnosis. METHODS: The following parameters were considered as prerequisites for a diagnosis of inflammatory bowel disease: clinical and endoscopic data; proper sampling and handling of biopsies; and elementary microscopic lesions. We collected 345 cases from 13 centres. RESULTS: The date of onset and treatment were available for 13% and 16% of the cases, respectively. Endoscopy information was accessible for 77% of the cases. Endoscopic mapping was completed in 13% of the cases. In no cases were the biopsies oriented on acetate strips. The diagnosis was conclusive in 47% of the cases. Activity, epithelial disruption and crypt distortion were described in 35% of the reports with a conclusive diagnosis. CONCLUSION: Our study showed that the diagnostic prerequisites were widely unfulfilled, although approximately half of the diagnoses were conclusive for inflammatory bowel disease. Thus, in our assessment of clinical practice: (1) clinicians seldom provide suitable clinical and/or endoscopic information for a histological diagnosis and (2) histopathological diagnoses of inflammatory bowel disease are often not supported by morphology.

This report contains clinically oriented guidelines for the diagnostic work-up and follow-up of cystic pancreatic neoplasms in patients fit for treatment. The statements were elaborated by working groups of experts by searching and analysing the literature, and then underwent a consensus process using a modified Delphi procedure. The statements report recommendations regarding the most appropriate use and timing of various imaging techniques and of endoscopic ultrasound, the role of circulating and intracystic markers and the pathologic evaluation for the diagnosis and follow-up of cystic pancreatic neoplasms.
