The serological support for early diagnosis and differential diagnosis of inflammatory bowel diseases (IBDs) is actually very limited. In this study, we evaluated the performance of a promising multiparametric method including either well-established and newly developed biomarkers. We conducted a multicenter cross-sectional study at the Gastroenterology Units of Udine (Italy), Rijeka (Croatia) and Belgrade (Serbia). Sera was collected from IBD patients, and autoantibody profiles were determined using a mosaic cell and tissue-based indirect immunofluorescence (IIF) method simultaneously investigating anti-saccharomyces cerevisiae antibodies (ASCAs), anti-atypical perinuclear neutrophilic antibodies (P-ANCAs), anti-pancreatic antigens antibodies (PABs) and anti-goblet cells antibodies (GAB). The study finally enrolled 156 patients with IBD: 100 affected by Crohn’s disease (CD) and 56 by ulcerative colitis (UC). Twenty age-sex matched blood donors (BDs) were included as controls. PAB (anti-CUZD1 and/or anti-GP2 antibodies) were present in 24 CD patients versus none of the UC patients or BDs (24% sensitivity, 100% specificity). As regards CD patients, combined positivity of PAB and ASCA (sensitivity 84%, specificity 71.4%) performed better than ASCA alone. Colon involvement (87.5% vs. 60.5%; p = 0.014), deep mucosal lesions (58.3% vs. 25.0%; p = 0.002) and need for biologic therapies (79.2% vs. 46.1%; p = 0.005) were significantly more prevalent in PAB-positive than in PAB-negative CD patients. Multivariate analysis identified PAB positivity (OR = 3.67; 95%CI = 1.29–10.46) and anti-CUZD1 in particular (OR = 3.54; 95%CI = 1.08–11.63) as significant risk factors for deep mucosal lesion development in CD. A multiparametric diagnostic approach appears very useful to better characterize IBD patients. PABs, whether isolated or combined with other autoantibodies, may support differential diagnosis but above all facilitate the selection of CD patients at risk for more severe disease. © 2024 by the authors.

BACKGROUND: Stenting of malignant hilar strictures remains a standard endoscopic treatment in patients with unresectable tumors. The aim of this two-center prospective study was to compare unilateral versus bilateral drainage in hilar malignant stenosis Bismuth-Corlette type II. METHODS: During a 3-year period, a total of 49 patients with hilar tumors (Bismuth-Corlette type II) were referred for endoscopic treatment, following the criteria of unresectability. Ultrasound, computed tomography scan and magnetic resonance cholangiopancreatography (MRCP) were previously performed in all patients in order to facilitate endoscopic retrograde cholangiopancreatography (ERCP). The stricture was first passed by the hydrophilic guide-wire and then contrast medium was injected. Mechanical bile duct dilation was performed, followed by plastic stent placement only in the liver lobe which was previously opacified. The procedures were performed under conscious sedation. The patients were followed up for the next 12 months with a stent exchange every 3 months. Primary outcome was assessed by patient survival in the first 12 months after the procedure. RESULTS: All 49 patients were treated with ERCP while 39 (79.59%) had successful stent placement. Among these, 32 had hilar cholangiocarcinoma (82%) and 7 (18%) had gallbladder cancer. Two groups of patients had Bismuth II strictures: A, 21 patients (54%) with unilateral contrast injection and drainage, and B, 18 (46%) with bilateral contrast injection and drainage. A total of 57 plastic stents were used (10 Fr, 89%; 11.5 Fr, 11%). Group B showed a lower bilirubin level 7 days after the procedure (P=0.008). Early complications were cholangitis (3 patients, 2 in group A and 1 in group B) and acute pancreatitis (2 patients, 1 each in A and B) with no statistical difference between the groups. Late complications were stent migration (5 patients, 1 in A and 4 in B) and stent clogging (6 patients, 2 in A and 4 in B) showing a significant difference between the groups (P<0.01). The first stent replacement after 3 months was successful in 87% of patients (four died due to disease progression and one due to cardiopulmonary insufficiency) showing no statistical difference between the groups. At 6 months follow-up, 72% patients survived, with no statistical difference between the groups. A final follow-up (12 months) showed the survival rate of 18% (4 patients from group A and 3 from group B) (P>0.05). CONCLUSIONS: A minimally invasive approach, based on the criterion that every bile duct being opacified needs to be drained, is associated with a lower incidence of early complications. Considering that the clinical outcome measured by bilirubin level was lower in patients with bilateral drainage 7 days after the procedure, we assumed that drainage of 50% or more of the liver volume leads to sufficient drainage effectiveness. © 2012, Hepatobiliary Pancreat Dis Int.

Objectives Colorectal cancer (CRC) is one of the most common malignancies worldwide. The aim of this study was to compare the outcomes of two different screening approaches in a small country (Montenegro, 650 000 inhabitants) with a CRC incidence lower than the European average. Methods Two structured invitation programs were compared with respect to compliance and neoplasia yield: (i) program A focused on first-degree relatives of CRC patients diagnosed in two hospitals (n=206), inviting them for colonoscopy; (ii) program B was an invitation program for fecal occult blood testing, followed by colonoscopy if positive, conducted in University Hospital, Podgorica, Montenegro, on 2760 randomly selected average-risk persons, age 50-74 years, living in a single municipality. Results Of 710 first-degree relatives of 206 CRC patients approached, 540 presented for colonoscopy (76.05% uptake). Overall, 31 were diagnosed with a cancer, 58 with advanced adenoma, and 151 with adenoma in general. In the general screening program, of 2760 individuals invited, 920 underwent fecal immunochemical test (33.3% uptake) and colonoscopy was performed in all 95 positive cases (10.3%); six cancers was found in five patients (one patient had two cancers), 19 patients were diagnosed with advanced adenoma, and 26 with any adenomas. The risk-targeted screening program had a significantly higher yield for cancers in both per invited (31/710 vs. 5/2760, P<0.001) and per eligible person analysis (31/540 vs. 5/920, P<0.001). Conclusion In a low-incidence country with limited resources, it may be advisable to start with CRC screening targeted to risk groups. Copyright © 2015 Wolters Kluwer Health, Inc.

Background & Aims: A hybrid technique may be a reasonable compromise to make endoscopic mucosal resection (EMR) more reliable for lesions ≥ 20 mm and a good way of approaching to endoscopic submucosal dissection (ESD). The aim of this study was to assess the efficacy and safety of a novel hybrid EMR technique, triple-anchoring EMR (T-EMR) for colorectal lesions 20-30 mm. Methods: Fifteen patients have been prospectively enrolled to T-EMR from December 2019 to April 2020 in two Endoscopy Units: Policlinico A. Gemelli, Rome, and University Hospital of Udine, Italy. Patients eligible for the study were ≥18 years old with superficial colorectal lesions 20-30 mm, morphologically liable to endoscopic treatment based on chromoendoscopy. The primary endpoint was assessment of the “en bloc” and the free resection margins (R0) rates. The secondary endpoints were resected specimen size, procedure time, complication rate, and recurrence rate at 6 months. Results: Among the 15 patients enrolled, 12 were males (80%), mean age 68.73±11.04 years. The mean size of the lesions was 24.93±2.89 mm. Mean procedure time was 22.13±4.31 min. T-EMR was performed en bloc in 14/15 patients (93.3%) with R0 in 13/15 patients (86.7%). No major intra-/peri-procedural or delayed complications occurred. At histological analysis, 13/15 lesions (86.7%) were adenomas, while 2 were early colorectal cancer. At a 6-month follow-up colonoscopy, only one patient (6.7%) had a recurrence of adenoma. Conclusions: T-EMR seems to be an effective and safe option to treat colorectal lesions between 20 and 30 mm, with a short procedure time and low costs. © 2022, Romanian Society of Gastroenterology.

Background and aim Postendoscopic retrograde cholangiopancreatography (post-ERCP) pancreatitis (PEP) is the most common complication following ERCP. We carried out a systematic review and meta-analysis of the global literature on PEP prevention to provide clinical guidance and a framework for future research in this important field. Methods PubMed, Embase, Science Citation Index, Ovid, and the Cochrane Controlled Trials Register were searched by two independent reviewers to identify full-length, prospective, randomized controlled trials (RCTs) published up until March 2016 investigating the use of pancreatic duct stents and pharmacological agents to prevent PEP. Results Twelve RCTs comparing the risk of PEP after pancreatic duct stent placement (1369 patients) and 30 RCTs comparing pharmacological agents over placebo (10251 patients) fulfilled the inclusion criteria and were selected for final review and analysis. Meta-analysis showed that prophylactic pancreatic stents significantly decreased the odds of post-ERCP pancreatitis [odds ratio (OR), 0.28; 95% confidence interval (CI), 0.18-0.42]. Significant OR reduction of PEP was also observed in relation to rectal administration of diclofenac (OR, 0.24; 95% CI, 0.12-0.48) and rectal administration of indometacin (OR, 0.59; 95% CI, 0.44-0.79) compared with placebo. Subgroup analysis showed a significant reduction with bolus-administered somatostatin (OR, 0.23; 95% CI, 0.11-0.49). Subgroup analysis showed a significant reduction with bolus-administered somatostatin (OR, 0.23; 95% CI, 0.11-0.49). Conclusion Pancreatic stent placement, rectal diclofenac, and bolus administration of somatostatin appear to be most effective in preventing post-ERCP pancreatitis.

6BACKGROUND. The etiology of tumors arising in the biliary tract remains unclear. Several previous studies have detected Helicobacter pylori organisms in bile from patients with gallstones or cholecystitis. The objective of this study was to determine whether there is an association between H. pylori in bile and biliary tract carcinoma. METHODS. The authors used polymerase chain reaction (PCR) assays to detect the presence of H. pylori in the stomach and bile from 89 patients: Sixty-three disease free patients had biliary calculi, 15 patients had carcinoma of the biliary tract, and 11 patients had neither gallstones nor carcinoma. Bile was considered to contain H. pylori only if the results of PCR determinations were positive in two or more samples assayed independently in two separate laboratories. RESULTS. There was a strong association between the presence of H. pylori in the stomach and in the bile (P≤0.01). Biliary H. pylori was associated with age but not with gender, and it was associated strongly with the clinical diagnosis. Patients with gallstones were 3.5 times as likely to have H. pylori in the bile compared with patients in a control group (95% confidence interval [95%Cl], 0.8-15.8; P = 0.100), and H. pylori was 9.9 times more frequent in patients with biliary tract carcinoma compared with patients in the control group (95%Cl, 1.4-70.5; P = 0.022). CONCLUSIONS. There is a strong association between biliary tract carcinoma and H. pylori in bile. If these results are confirmed by prospective studies, H. pylori may be responsible for a significant proportion of malignant biliary tract disease. © 2002 American Cancer Society.

Background/Objectives: Perforations represent rare but serious complications in ERCP. Although several therapeutic algorithms have been proposed to properly address these potentially life-threatening events, there is still no clear consensus on their management. We conducted a single-center retrospective study in order to assess the incidence of ERCP-related perforations and their management, as well as clinical outcomes. Methods: The hospital’s electronic database was searched in order to identify all the patients who developed ERCP-related perforations in the period 1 October 2018–30 June 2023. Perforations were classified according to the Stapfer classification. Conservative management included frequent abdominal examinations, the monitoring of vital signs, white blood cell count, complete bowel rest, nasogastric tube placement, and the administration of intravenous fluids and antibiotics. Endoscopic management included biliary stent placement and/or closing observed defects with clips. Results: We recorded eight (1.29%) cases of ERCP-related perforations out of the 619 procedures conducted. We observed six (75%) Stapfer type II and two (25%) type IV perforations. In all but one patient (87.5%), the indication for ERCP was bile duct stones. Seven patients (87.5%) were subjected to sphincterotomy (87.5%) and three (37.5%) to “pre-cuts”. All but one patient was treated conservatively (87.5%), with two of them—in which type II perforations were recognized intraprocedurally—also receiving endoscopic treatment with stent placement. On the day of ERCP, one patient with a type II perforation was operated on; suturing of the duodenum followed by duodenal exclusion was applied. Management was successful in all the patients, with a mean hospitalization time of 16.6 ± 4.78 days. Conclusions: Conservative and endoscopic management appear to be associated with good outcomes in Stapfer type II perforations. Nevertheless, an individual multidisciplinary approach involving endoscopists and a hepatobiliary surgeon is essential in order to properly guide the treatment. © 2024 by the authors.

Introduction: Although pancreatic tuberculosis (TB) is traditionally considered to be a rare clinical entity, in recent times, an increase in the number of reports of pancreatic TB has been noted. We conducted a systematic review in order to summarise currently available data on pancreatic TB. Methods: A comprehensive literature search of Medline, Scopus and ISI Web of Science databases was conducted in order to identify papers reporting cases of pancreatic TB. The eligibility criteria for inclusion in the review required that the studies reported patient(s) affected by pancreatic TB and that individual data on age, sex, clinical presentation and outcome were available. Results: In total, 116 studies reporting data on 166 patients were included in the analysis. The majority of patients were males (62.1%) diagnosed at a mean age of 41.61 ± 13.95 years. Most cases were diagnosed in Asia (50.0%), followed by North America (22.9%), Europe (20.5%), Africa (4.2%) and South America (2.4%). Human immunodeficiency virus (HIV) infection was diagnosed in 25.3% of those affected. Pancreatic TB most frequently presented itself in the form of a pancreatic mass (79.5%) localised mainly in the head (59.0%) and less frequently in the body (18.2%) and tail (13.4%). Extrapancreatic TB involvement most frequently affected the peripancreatic lymph nodes (47.3%). More than half of patients (55.2%) were subjected to laparotomy, while 21.08% underwent endoscopic ultrasound fine-needle aspiration biopsy. The presence of TB was identified most frequently through histological analysis (59.6%), followed by culture (28.9%), staining (27.7%) and, in a smaller number, by polymerase chain reaction (9.6%) and cytology (6.6%). Almost all patients received anti-tubercular pharmacological therapy (98.2%), while 24.1% underwent surgery. Despite treatment, 8.7% of patients died. Conclusion: Increased awareness of pancreatic TB is needed, not only in endemic areas but especially in relation to HIV infection and other clinical conditions associated with immunoincompetence. © Author(s) 2020.

Background: We conducted a systematic review in order to summarize the available data on pancreatitis associated with viral hepatitis. Methods: A comprehensive literature search of Medline, Scopus and ISI Web of Science databases was conducted and papers eligible for the inclusion identified. Results: In total, 46 studies reporting data on 73 patients were included in the analysis. Most of the cases were diagnosed in Asia (57.53%), followed by North America (23.29%), and Europe (13.70%). Most of the patients were affected by hepatitis A virus (HAV) (42.47%), followed by hepatitis E virus (HEV) (28.77%), hepatitis B virus (HBV) (8.22%), and hepatitis C virus (HCV) (1.37%), while 17.81% at the time of diagnosis were classified as affected by “hepatitis virus”. Pancreatitis was severe in 32.88% of cases. The respiratory system was affected in 2.74% of patients, 6.85% experienced renal failure, while 5.48% experienced a multiorgan dysfunction syndrome (MODS). Four patients (5.48%) needed pancreatic surgery. Despite the treatment, 21.92% of patients died. We identified fulminant hepatitis (p < 0.0001), MODS (p < 0.0001) and severe pancreatitis (p < 0.0001) to be significantly more present in patients who died in comparison to cured ones. Conclusion: Increased awareness of pancreatic involvement in viral hepatitis is needed because it can have a substantial impact on therapeutic approaches and outcomes. © 2020 by the authors.

Recognition of Helicobacter pylori as an important factor in genesis of gastric adenocarcinoma lead to a large number of studies concerning potential role of Helicobacter spp. in the development of extragastric digestive malignancies. The serological studies indicated possible localizations in the digestive system being from interest in enlightening Helicobacter spp. carcinogenic potential. The PCR obtruded itself as a gold standard in proving existence of actual correlation. In this review, the authors have examined studies conducted in the last 10 years examining Helicobacter spp. correlation with extragastric digestive carcinogenesis. Studies have been observed in four groups referring to hepatic carcinoma, bile duct cancer, pancreatic cancer, and colon cancer. The results of these researches have shown that there is a strong correlation between Helicobacter spp. colonization and primary liver tumors as well as bile duct tumors, whereas conclusions made by authors examining pancreatic cancer are contradictory and demands further investigation. No correlation between Helicobacter spp. and colon cancer have been proven. The PCR subtype most widely used in studies included in this review was nested PCR, whereas genes targeted most frequently for amplification are 16S rDNA of Helicobacter spp. and UreA gene or cagA gene of H. pylori. During the last 10 years PCR has proven itself as a sovereign method for Helicobacter spp. diagnostic in extragastric organs in the digestive system. Knowledge and experiences obtained in this domain could be encouraging for researchers in analogous fields of interest. © 2012 Wolters Kluwer Health | Lippincott Williams & Wilkins.

BACKGROUND AND AIMS: The most common complications after liver transplantation nowadays affect the biliary tract.We carried out a retrospective study to identify predictors of endoscopic treatment outcome in the management of post-transplantation biliary complications. METHODS: Data from all patients with post-transplantation biliary complications subjected to endoscopic treatment at the University of Udine between 2000 and 2012 were extracted. To identify predictors of endoscopic treatment outcome, a logistic regression analysis was carried out. Cox modeling was used to identify factors associated with mortality. RESULTS: We identified 142 patients who developed biliary complications: 83 of these patients had a successful endoscopic therapy, whereas 45 had a failure. Fourteen patients, who developed nonanastomotic biliary stricture, were excluded from the analysis. Patients with biliary complications who had pretransplant Model for End-Stage Liver Disease score more than 10 [odds ratio (OR) 3.88; 95% confidence interval (CI) 1.16-12.95; P=0.03] and stent retention time more than 12 months (OR 6.45; 95% CI 2.14-19.42; P<0.01) were less likely to respond to endoscopic therapy. In contrast, both dilatation and stenting procedures (OR 0.10; 95% CI 0.03-0.30; P<0.01) and 10Fr diameter stent placement (OR 0.21; 95% CI 0.07-0.70; P=0.01) predicted favorable endoscopic treatment outcome. Time to the occurrence of biliary complications of more than 3 months [hazard ratio (HR) 0.24; 95% CI 0.10-0.56] and placement of five or more stents (HR 0.31; 95% CI 0.12-0.79) were found to be protective against mortality, whereas hepatic artery thrombosis was a significant risk factor for mortality (HR 13.88; 95% CI 4.08-47.25). CONCLUSION: We found endoscopic treatment to be less effective in patients with pretransplant Model for End-Stage Liver Disease score more than 10 and stent retention time more than 12, whereas dilatation and stenting procedure and 10Fr diameter stent placement predicted a favorable outcome. © 2015 Wolters Kluwer Health, Inc.

Background & Aims: Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas have been reported to be associated with an increased risk of developing extra-pancreatic malignancies. A common genetic background has been hypothesised to be responsible for such an association. Human chromosomal region 8q24 has been associated with many types of cancer. The majority of these associations lie at approximately 128 Mb on chromosome 8. We conducted a study in order to examine the association between IPMN and single nucleotide polymorphisms (SNPs) from the 8q24 region, namely rs10505477, rs6983267, rs7014346, rs6993464, previously reported to influence general cancer susceptibility. Methods. The study was performed on 117 IPMN cases and 231 controls. Cases were enrolled at the Digestive Endoscopy Unit, Policlinico Agostino Gemelli from January, 2010 to June, 2011, with either a prevalent or incident IPMN diagnosis. Status of SNPs was determined using a StepOne Real-time PCR system (Applied Biosystems) and TaqMan SNP Genotyping Assay™ 40X. Unconditional multiple logistic regression models were used to estimate odds ratios and 95% confidence intervals for the association of selected SNPs and IPMNs. Results. Cases were more likely to report a 1st degree family history of cancer (p<0.001), as well as heavy smoking (p=0.001) and heavy drinking habits (p<0.001). No significant association was observed between IPMN and selected SNPs. The results were confirmed also when stratified according to any 1st-degree family history of cancer. Conclusion. Patients with IPMN do not have a higher prevalence of SNPs in the human chromosomal region 8q24 in respect to the control population. © 2016, Romanian Society of Gastroenterology.

Introduction and Aims: Patients treated with intragastric balloon (IGB) may benefit from treatment and follow-up by a multidisciplinary team, where the dietician is considered the only essential professional besides the endoscopist. The aim of this study is to evaluate the impact of dietician support and behavioral therapy in terms of weight loss in patients concomitantly treated with IGB while the device is in situ. Methods: Patients with IGB in situ, in period 2005–2018, were invited to undergo a dietician check-up (DC) every 1.5 months, accompanied by cognitive behavioral therapy. Considering their attendance at the dietician check-ups (DCs), patients were categorized as non-compliant (0 DC), partially compliant (1–2 DCs), and highly compliant (≥ 3 DCs). A comparison was made among the three groups regarding % of total body weight loss (%TBWL) and ΔBMI at 180 ± 15 days when the IGB was in situ. Results: One hundred eighty-three obese patients treated with fluid-filled IGB were included. Body weight data at 180 ± 15 days during the IGB in situ, as well as attendance at the DCs, were available for 170 out of 183 patients. There was no difference among compliant, partially compliant, and non-compliant patients to DCs regarding %TBWL at 180 ± 15 days (p = 0.17). However, non-compliant patients had a higher ΔBMI at 180 ± 15 days in comparison to those compliant or partially compliant to DCs (p = 0.03). Conclusion: Despite its undisputed educational role, attendance at DCs does not seem to correlate with an additional weight loss while the IGB is in situ. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.
