Scores in upper GI bleeding (UGIB) are used to stratify death risk and need for hospitalization at admission, but a tool that incorporates dynamic changes during the hospital stay is lacking. We aimed to develop a death risk score that considers changes in clinical status during hospitalization and compare its performance with existing ones.A multicenter cohort study enrolling patients with UGIB in 50 Italian hospitals from January 2014 to December 2015 was conducted. Data were collected and used to develop a risk score using logistic regression analyses. Performance curves (area under the receiver-operating characteristic [AUROC] curves), sensitivities, specificities, positive and negative predictive values, and outcomes classified as low, intermediate, and high death risk were calculated. The score's performance was externally validated and then compared with other scores.We included 1852 patients with nonvariceal UGIB in the development cohort and 912 in the validation cohorts. The new score, which we named the Re.Co.De (rebleeding-comorbidities-deteriorating) score, included 10 variables depicting the changes in clinical conditions while in the hospital. The mortality AUROC curves were .93 (95% confidence interval, .91-.96) in the derivation cohort and .94 (95% confidence interval, .91-.98) in validation cohort. In a comparison of AUROC curves with other scores, the new score showed a significant performance compared with pre- and postendoscopy scores. Patients with low and high scores had 30-day mortality rates of .001% and 48.2%, respectively.The Re.Co.De score has a higher performance for predicting mortality in patients with UGIB compared with other scores, correctly identifying patients at low and high death risk while in the hospital through a dynamic re-evaluation of clinical status.

Objectives A continuous 13-h infusion of gabexate starting 30–90 min before endoscopic cholangiopancreatography (ERCP) can reduce postprocedural pancreatitis, the onset of which is generally observed within the first 6 h after ERCP. This study was designed to verify whether a 6.5-h infusion of gabexate was as effective as a 13-h infusion, at the same concentration, for reducing the incidence of post-ERCP pancreatitis (primary endpoint) and pancreatic hyperenzymemia and pain (secondary endpoints). Methods A total of 434 patients (201 male and 233 female; mean age 63.9 yr, range 18–96 yr) scheduled for ERCP were prospectively recruited in 25 Italian centers. Patients were randomized double-blind to two treatment groups. All subjects enrolled were first treated with a 500-mg continuous intravenous infusion of gabexate, starting 30 min before the endoscopic maneuvers and continuing up to 6.5 h after it. Over the next 6.5 h, 214 patients (group I) continued the infusion of gabexate (for a total of 1 g over 13 h) and 220 patients (group II) were given placebo (saline solution). Results The overall incidence of acute pancreatitis was 1.8% (eight patients), which included 1.4% in group I (three of 214 patients) and 2.2% in group II (five of 220 patients). Serum amylase and lipase values over time, peak levels of the two enzymes, pancreatic pain, and need for analgesics did not significantly differ in the two groups. Conclusions These results suggest that a 6.5-h infusion of gabexate (for a total of 500 mg) is not less effective than a 13 h infusion, with evident savings.

OBJECTIVE: This study aimed to evaluate the surgical treatment of acute pancreatitis in Italy and to assess compliance with international guidelines. METHODS: A series of 1173 patients in 56 hospitals were prospectively enrolled and their data analysed. RESULTS: Twenty-nine patients with severe pancreatitis underwent surgical intervention. Necrosectomy was performed in 26 patients, associated with postoperative lavage in 70% of cases. A feeding jejunostomy was added in 37% of cases. Mortality was 21%. Of the patients with mild pancreatitis, 714 patients with a biliary aetiology were evaluated. Prophylactic treatment of relapses was carried out in 212 patients (36%) by cholecystectomy and in 161 using a laparoscopic approach. Preoperative endoscopic retrograde cholangiopancreatography was associated with cholecystectomy in 83 patients (39%). Forty-seven patients (22%) were treated at a second admission, with a median delay of 31 days from the onset of pancreatitis. Eighteen patients with severe pancreatitis underwent cholecystectomy 37.9 days after the first admission. There were no deaths. DISCUSSION: The results indicate poor compliance with published guidelines. In severe pancreatitis, early surgical intervention is frequently performed and enteral feeding is seldom used. Only a small number of patients with mild biliary pancreatitis undergo definitive treatment (i.e. cholecystectomy) within 4 weeks of the onset of pancreatitis.

Background Endoscopic retrograde cholangiopancreatography (ERCP) is associated with elevated levels of pancreatic enzymes and pancreatitis. Gabexate, a protease inhibitor, has been used to prevent pancreatic damage related to ERCP. Methods We conducted a multicenter, double-blind comparison of gabexate (1 g given by intravenous infusion starting 30 to 90 minutes before endoscopy and continuing for 12 hours afterward) with placebo (mannitol and sodium chloride, administered in the same fashion). A total of 435 adults scheduled to undergo ERCP and, when indicated, endoscopic sphincterotomy underwent randomization; 17 were excluded from the final analysis for various reasons. The remaining 418 patients (mean age, 60.4 years) — 208 in the gabexate group and 210 in the placebo group — were analyzed. Acute pancreatitis was considered to be present if serum amylase or lipase levels (or both) were five times greater than the upper limits of normal in association with the onset of pancreatic pain. Results After th...

PillCam colon capsule endoscopy (CCE) is an innovative noninvasive, and painless ingestible capsule technique that allows exploration of the colon without the need for sedation and gas insufflation. Although it is already available in European and other countries, the clinical indications for CCE as well as the reporting and work-up of detected findings have not yet been standardized. The aim of this evidence-based and consensus-based guideline, commissioned by the European Society of Gastrointestinal Endoscopy (ESGE) is to furnish healthcare providers with a comprehensive framework for potential implementation of this technique in a clinical setting. © Georg Thieme Verlag KG Stuttgart.

These recommendations on video capsule endos copy, an emerging technology with an impact on the practice of endoscopy, were developed by the European Society of Gastrointestinal Endoscopy (ESGE) Guidelines Committee. The first draft of each section was prepared by one or two members of the writing team, who were selected as experts on the content of that section on the basis of their published work. They used evidence-based methodology, performing MEDLINE and PubMed literature searches to identify relevant clinical studies. Abstracts from scientific meetings were included only if there was no published full paper on a particular topic. If there was disagreement, the first author of the Guideline made the final decision. Recommendations were graded according to the strength of the supporting evidence (Table1). The draft guideline was critically reviewed by all authors and submitted to the ESGE councillors for their critical review be fore approval of the final document. The ESGE Guidelines Committee acknowledges that this doc ument is based on a critical review of the data available at the time of preparation and that further studies may be needed to clarify some aspects. Moreover, this Guideline may be revised as necessary to account for changes in technology, new data, or other aspects of clinical practice. This document should be regarded as supplying recommendations only to gastroenterologists in providing care to their patients. It is not a set of rules and should not be construed as establishing a legal standard of care, or as encouraging, advocating, requiring, or discouraging any particular treatment. These recommendations must be interpreted according to the clinicians knowledge, expertise, and clinical judgment in the management of individual patients and, if necessary, a course of action that varies from recommenda tions must be undertaken. © Georg Thieme Verlag KG Stuttgart New York ISSN 0933-811X.

Up till now, only one study providing practically complete information on acute pancreatitis in Italy has been published. The aim of this prospective study was to evaluate the clinical characteristics, in terms of diagnostic assessment and outcome, of a large series of patients affected by acute pancreatitis in Italy.The study involved 56 Italian centres, homogeneously distributed throughout the entire national territory. Each participating centre was furnished with an ad hoc software including 530 items along with subsequent collection, tabulation and quality control of the data.One thousand five hundred and forty case report forms of patients affected by acute pancreatitis were collected but 367 of them (24%) were subsequently eliminated from the final analysis. Therefore, 1173 patients (581 females and 592 males) were recruited. Mean age of patients was 62.0+/-18.2 years (95% confidence interval, 60.9-63.0). On the basis of Atlanta classification, 1006 patients (85.8%) were defined as mild and 167 (14.2%) as severe pancreatitis. Biliary forms represented the most frequent aetiological category (813 cases, 69.3%) while alcoholic forms only 6.6% (77 cases); the remaining aetiologies accounted for 7.1% (83 cases) while 200 cases (17.1%) remained without a definite aetiological factor. Complete recovery was achieved in 1016 patients (86.6%) whereas morphological sequelae were found in 121 patients (10.3%) and mortality in 36 patients (3.1%; 0.4% in mild and 19.2% in severe acute pancreatitis). Ultrasonography was largely utilised as a first line diagnostic tool in all patients, with valuable visualisation of the pancreas in 85% of patients. Computer tomography scan was also widely used, with 66.7% of exams in mild and 33.3% in severe pancreatitis. Patients affected by biliary pancreatitis presented more severe (p=0.004) and necrotizing forms (p=0.021). Mortality was significantly related (p0.001) with the extension of pancreatic necrosis and with an age of over 70 years. Body mass index presented significantly greater values in severe than in mild forms (p0.001).Association of creatinine serum level over 2mg/dl with an abnormal chest X-ray showed a high significant correlation with a more severe outcome in terms of morphological sequelae and mortality (p=0.0001). Acute pancreatitis in Italy more commonly presents biliary aetiology and favourable outcome with low rate of complications and mortality. From a cost-effectiveness standpoint, diagnostic approach to this disease needs to be better standardised.

Oxygen-free radicalscan play a role in the development of chronic pancreatitis, altering the redox state with damage of cell constituents and decrease in antioxidant defences.To measure levels of lipoperoxidation products, conjugated dienes and lipid hydroperoxides, in pure pancreatic juice and serum of chronic pancreatitis patients and compare them to that in controls. To investigate a possible correlation with serum indexes of pancreatic inflammation (amylase and lipase).Pancreatic juice was collected during ERCP, after secretin stimulation, in 20 patients with chronic pancreatitis and 11 controls with biliary diseases.Lipid hydroperoxide levels were determined with FOX2 method and measured as absorbance at 560 nm. Conjugated diene levels were measured using second-derivative spectroscopy.No substantial difference was present in serum levels of lipid hydroperoxides, conjugated dienes (in both isomeric forms) and isomer-ratio values between those of patients with chronic pancreatitis and controls. In pancreatic juice, there was a significant increase in lipid hydroperoxides and conjugated dienes levels (especially trans-trans isomers) in chronic pancreatitis patients compared with controls, with a decrease in cis-trans isomers and a significant difference in isomer-ratio values.Increased levels of lipid hydroperoxides and conjugated dienes in the pancreatic juice of chronic pancreatitis patients is indicative of an enhanced lipoperoxidation and antioxidants consumption in pancreatic tissue, confirmed by the decreased isomer-ratio values as an indirect index of decreased antioxidant capacity. The lack of significant difference in conjugated diene and lipid hydroperoxide levels in the serum of chronic pancreatitis patients versus that of controls suggests an oxidative stress limited to pancreatic tissue and indicative of an organ-specific pathology, confirmed by the parallel behaviour of oxidative parameters (lipid hydroperoxides and conjugated dienes) and indexes of pancreatic inflammation (amylase and lipase).

In the diagnosis of exocrine diseases of the pancreas, three major questions should be addressed: when only MR cholangiopancreatography should be applied; when endoscopic retrograde cholangiopancreatography should be applied directly; when a combined approach should be applied. In pancreatic disease MRI has many indications because ultrasonography, the procedure of choice, is rarely able to resolve the diagnostic problem, with a clearcut indication for therapeutic endoscopic retrograde cholangiopancreatography. One of the rare cases where MRI could be omitted is represented by pancreatic cancer with biliary obstruction in non operable patients in whom a pancreatic mass was already visualized on ultrasonography. In all other diseases of the pancreas, the combination of MRI/MRCP with secretin stimulation and ERCP usually favors the first procedure, preventing a number of diagnostic ERCP.

In case of clinical and radiologic findings suggestive for periampullary cancer, primary goals of ERCP are the observation of the duodenum and the periampullary region and the opacification of biliopancreatic ducts to confirm the diagnosis of neoplastic stricture of biliopancreatic ducts and to establish its origin and extent at the level of the ducts and of the intestinal lumen. Secondarily, during ERCP, histologic and/or cytologic typing of the neoplasm by biopsy sampling and brushing of the lesion or exfoliative cytology of the bile and pancreatic juice, is feasible. At the level of the area of the pancreatic head various types of neoplasms can arise with different prognostic features which require different therapeutic approaches. Endoscopic cholangiopancreatography for its high sensitivity and specificity plays a major role in a correct combined radiodiagnostic imaging.

Jaundice is the dominant symptom in patients with biliary obstruction from carcinomas of the pancreatic head area. The many symptoms usually associated to prolonged biliary stasis (malnutrition, coagulopathy, pruritus hepatocellular failure, renal dysfunction, angiocolitis) is commonly resolved or relieved by biliary drainage. Palliation is frequently the only feasible treatment in these patients due to the biological aggressiveness of these tumors characterized by the early infiltration of adjacent tissues. Endoscopic and percutaneous procedures of biliary recanalization are as effective as those of surgical palliation, are more comfortable to the patients and burdened with a lower morbidity and mortality. In selected patients, palliation of jaundice can be combined with intraluminal radiotherapy or pancreatic drainage the latter aimed at the relief of the "obstructive" pain present in some patients with carcinoma of the area of the head of the pancreas.

Diagnostic and therapeutic endoscopic cholangio- pancreatography (ERCP) are more difficult in patients with Billroth II gastrectomy. A six-year experience including 274 ERCP in 175 Billroth II patients is reviewed. Overall diagnostic success-rate was 88.3% while a complete endoscopic treatment could be accomplished in 92.8% when indicated. Endoscopy related morbidity and mortality were 5.1% and 0 respectively, while in-hospital mortality was 2.3%. Diagnostic and therapeutic ERCP techniques in Billroth II patients are then discussed with special reference to the choice of the scope and of the accessories to perform a safe endoscopic sphincterotomy. The use of the lateral-viewing duodenoscope and of the long-nose sigmoid inverted sphincterotome (originally modified by our group) are emphasized. ERCP and endoscopic sphincterotomy in Billroth II subjects are today as safe and nearly as effective as in the non-gastrectomized patient.

After a brief examination of the technical problems of current pacemakers, with special reference to the battery state control, the authors present a new technique for such control. A power stabilizer able to generate a standard pulse of 4.3 in every condition of battery charge has been fitted on the power supply of a fixed rate pacemaker of normal production. By activating (through an external magnet) such apparatus, it is possible with an easy oscilloscopic measurement to obtain the real value of the battery voltage. Thus the comparison with previously taken measurements and the errors connected with the repetition of such measurements can be avoided. The stimulation rate and the pulse duration corresponding to the discharged state of the batteries can also be known in advance. The data obtained from the first two controls are reported.

A new case of Budd-Chiari syndrome following pregnancy is reported. The patient, shortly after her second normal delivery, showed clinical evidence of hepatic venous outflow impairment. The diagnosis of Budd-Chiari syndrome was supported by angiographic studies, computed tomography, liver scanning and histology. Because of the poor results reported in the literature following medical treatment, portosystemic shunting was considered. At laparotomy, due to the huge caudate lobe hypertrophy, a mesocaval H-graft shunt was performed, using a 10 mm woven Impraflex graft. The patient is well, with normal liver function tests, 24 months following the procedure.

Complications directly associated with the use of prosthetic materials in large hiatal hernia repair are rarely cited events in the literature. We herein report a case of a 47 year-old woman who came to our attention for a subacute onset of severe dysphagia and weight loss. She previously underwent laparotomic Nissen fundoplication with PTFE dual-mesh cruroplasty for a large recurrent hiatal hernia. With the clinical suspicious of "Tight Nissen", an endoscopy was performed and revealed a circular stenosis in the lower esophagus, a rotation of the stomach and, surprisingly, the presence of PTFE mesh free-moving in the gastric lumen With the use of rattooth forceps, the foreign body was removed and, after few days, the patient underwent a surgical debridement of hiatal scar tissue and a gastropexy procedure. In conclusion, dysphagia may manifest during the early postoperative period after mesh repair antireflux surgery, but such dysphagia usually resolves; if it doesn't or if it worsens, mesh migration must be excluded.

To explore the possibility that the preventive effect of gabexate mesilate on endoscopic retrograde cholangiopancreatography-related acute pancreatitis may be mediated by its modulation of acute phase proteins.Thirty consecutive patients who underwent endoscopic retrograde cholangiopancreatography were randomly assigned to receive 1g of gabexate mesilate (13 patients) or a placebo (17 patients) by continuous i.v. infusion starting 30 minutes before the endoscopy session and continuing for 12 hours afterward. In all patients, C-reactive protein, serum amyloid A and interleukin 6 serum concentrations were determined before endoscopy and 4, 8, 12 and 24 hours afterward.Interleukin 6 basal serum concentrations were not statistically different between patients who had been treated with gabexate mesilate and those who had received the placebo (P = 0.279), whereas C-reactive protein (P = 0.033) and serum amyloid A (P = 0.022) basal values were significantly lower in the gabexate mesilate group than in the placebo group. Compared to basal values, serum interleukin 6 concentrations significantly increased at 4 (P = 0.048) and at 8 (P = 0.025) hours; the increase of serum interleukin 6 concentrations was not significant at 12 (P = 0.092), but became significant at 24 (P = 0.025) hours. C-reactive protein and serum amyloid A serum concentrations increased significantly only at 12 (P = 0.001, P = 0.012, respectively) and 24 (P0.001, P = 0.013, respectively) hours. The modifications of serum concentrations of interleukin 6, C-reactive protein and serum amyloid A were not significantly different between the gabexate mesilate and the placebo groups.Gabexate mesilate does not affect serum concentrations of acute phase proteins after endoscopic retrograde cholangiopancreatography examination and it is able to prevent acute pancreatitis related to endoscopic retrograde cholangiopancreatography via a different mechanism than that explored in this study.

Nineteen patients with distal juxtapapillary choledochoduodenal fistula diagnosed by endoscopic retrograde cholangiopancreatography are reported. Eighty-four percent of the patients had undergone previous operations on the biliary tract. Fistula appears to be mostly secondary to common bile duct exploration with rigid probes or to a technical mistake in performing sphincteroplasty. Spontaneous fistula secondary to the passage of a stone into the duodenal lumen may also occur. Common duct stones were responsible for the symptoms in most cases (70%). Endoscopic sphincterotomy showed good results in cholecystectomized patients with stones. Surgery directed to the fistula or biliary by-pass are not recommended. Uncomplicated fistula probably does not require treatment.

This study was designed to evaluate the effectiveness of radical surgery for liver hydatid disease.Hospital charts of 104 consecutive patients with liver hydatidosis observed in our unit during the period 1982-1994 were reviewed. A total of 121 cysts in 89 patients were treated surgically: with cystopericystectomy in 66 and liver resection in 23.The overall incidence of postoperative complications was 19%: 19.7% and 17.1% after cystoperi-cystectomy and liver resection respectively (p = 0.32). Overall postoperative mortality was 1%. Among the 72 patients available for follow-up, only one (1%) had a local recurrence of the disease.Results suggest the safety and efficacy of radical procedures in the surgical management of liver hydatid disease. Total cystopericystectomy is the treatment of choice but liver resection is justified in selected cases.

Acute diarrhea is a very common symptom, which may recognize different causes and is basically the expression of an altered homeostasis of the bowel, which overcame current classifications. When approaching patients with acute diarrhea, we should firstly check body temperature and vital parameters and secondly provide a general medical examination mainly focused on the abdomen, in order to exclude surgical causes of diarrhea, such as acute appendicitis, diverticulitis, intestinal occlusion and others. Another important aspect is the assessment of the level of hydration in order to provide the right amount of fluids. There is no current indication for the administration of loperamide in infectious diarrhea, but there is a strong rationale for new class of drugs, which may be defined as "mucous regenerators", such as gelatin tannate. Further studies are needed on this matter in order to test the effect of gelatin tannate in adult patients with acute diarrhea.

The role of ERCP and endoscopic drainage in the diagnosis and treatment of patients with malignant biliary obstruction is well established. Endoscopic drainage is an effective therapy for palliation of malignant obstructive jaundice and does not preclude definitive treatment in appropriate candidate. We report our experience, in a retrospective review, of 505 patients with malignant biliary obstruction. In this series, endoscopic biliary drainage is shown to be safe and effective management for these patients. Relief of obstruction was obtained in a large majority of patients with a low, procedure related, morbidity and mortality. We conclude that ERCP, to diagnose and localize obstructive lesions, followed by endoscopic biliary drainage can be strongly considered in all patients with suspected malignant obstructive jaundice.

Endoscopic drainage is an effective therapy for palliation of patients with bile duct carcinoma. From November 1987 to November 1994 112 patients with cholangiocarcinoma were observed. The success rate of the procedure was 94.5%. The biliary drainage was successful in 99% of patients (in 4% of patients the complete biliary drainage was obtained with the aid of a transhepatically inserted guide-wire with the "rendez-vous" procedure). In 15 patients an intraluminal radiation therapy with Iridium-192 was associated. The morbility was 13% and the 30-days mortality 11%. A surgical operation was performed in 26% of patients with radical intent. The mean survival time in patients treated only endoscopically was 208 days for patients with lesions of the distal and middle third of the bile duct and 281 days for patients with hilar cholangiocarcinoma. In patients with intraluminal radiation therapy the mean survival time was 357 days, with a significative difference with the only endoscopically treated group (357 vs 238 days, p0.05). We conclude that endoscopic drainage is a safe and effective management for patients with cholangiocarcinoma and it does not preclude definitive surgical treatment in appropriate candidate.

Differential diagnosis of pancreatic cancer versus chronic pancreatitis may be difficult. The aim of this study is to determine whether a group of tumor-associated antigens could differentiate between the two pathologies.CA 19-9, TAG-72, CAR-3, and a newly discovered antigen termed "90K" were determined in the serum and in the pancreatic juice of 19 patients with pancreatic cancer, 20 patients with chronic pancreatitis, and seven controls with lithiasis of extrapancreatic bile ducts.The serum antigen levels of all three markers except 90K were significantly higher in pancreatic cancer than in chronic pancreatitis. High correlations were found between serum CA 19-9 and both TAG-72 and CAR-3. 90K did not correlate with other markers. In pancreatic juice, only 90K values were significantly higher in chronic pancreatitis than in pancreatic cancer, and only 90K and CA 19-9 were significantly correlated. At the stepwise discriminant analysis, serum CA 19-9 and pancreatic juice 90K had independent diagnostic roles. Used in combination, they correctly identified 84.2% of pancreatic cancer and 90% of chronic pancreatitis.These data suggest that pancreatic juice 90K and serum CA 19-9 can discriminate between chronic pancreatitis and pancreatic cancer. The data further support the complementary use of tumor-associated antigens along with other diagnostic tools.

The mechanisms underlying bowel disturbances in coeliac disease are still relatively unclear. Past reports suggested that small bowel motor abnormalities may be involved in this pathological condition; there are no studies addressing small bowel transit in coeliac disease before and after a gluten-free diet.The objective of this study was to determine whether capsule endoscopy (CE) could serve as a test for measurement of gastric and small bowel transit times in a group of symptomatic or asymptomatic coeliac patients at the time of diagnosis with respect to a control group.Thirty coeliac untreated patients and 30 age-, sex- and BMI-matched healthy controls underwent CE assessment of whole gut transit times.All subjects completed the study per protocol and experienced natural passage of the pill. No statistical significant differences between gastric emptying and small bowel transit times both in coeliac and control group were found (p = 0.1842 and p = 0.7134; C.I. 95%, respectively). No correlation was found in coeliac patients and control group between transit times and age, sex and BMI. By using the Pearson's correlation test, significant correlation emerged between gastric emptying time and small bowel transit times in coeliac disease (r = 0.1706).CE reveals unrecognized gender differences and may be a novel outpatient technique for gut transit times' assessment without exposure to radiation and for the evaluation of upper gut dysfunction in healthy patients suffering from constipation without evidence of intestinal malabsorption. Nevertheless, CE does not seem to be the most suitable method for studying gut transit times in untreated coeliac patients; this might be ascribed to the fact that CE consists of inert (non-digestible, non-absorbable) substances.

BACKGROUND: Autoimmune pancreatitis (AIP) is a rare, and relatively new, form of chronic pancreatitis. The management of AIP can vary considerably among different centres in daily clinical practice. OBJECTIVES: The aim of this study is to present a picture of epidemiological, clinical characteristics, outcomes, and the real-life practice in terms of management in several academic and non-academic centres in Italy. METHODS: Data on the clinical presentation, diagnostic work-up, treatments, frequency of relapses, and long-term outcomes were retrospectively collected in a cohort of AIP patients diagnosed at 14 centres in Italy. RESULTS: One hundred and six patients were classified as type 1 AIP, 48 as type 2 AIP, and 19 as not otherwise specified. Epidemiological, clinical, radiological, and serological characteristics, and relapses were similar to those previously reported for different types of AIP. Endoscopic cytohistology was available in 46.2% of cases, and diagnostic for AIP in only 35.2%. Steroid trial to aid diagnosis was administered in 43.3% cases, and effective in 93.3%. Steroid therapy was used in 70.5% of cases, and effective in 92.6% of patients. Maintenance therapy with low dose of steroid (MST) was prescribed in 25.4% of cases at a mean dose of 5 (±1.4) mg/die, and median time of MST was 60 days. Immunosuppressive drugs were rarely used (10.9%), and rituximab in 1.7%. Faecal elastase-1 was evaluated in only 31.2% of patients, and was pathological in 59.2%. CONCLUSIONS: In this cohort of AIP patients, diagnosis and classification for subtype was frequently possible, confirming the different characteristics of AIP1 and AIP2 previously reported. Nevertheless, we observed a low use of histology and steroid trial for a diagnosis of AIP. Steroid treatment was the most used therapy in our cohort. Immunosuppressants and rituximab were rarely used. The evaluation of exocrine pancreatic insufficiency is underemployed considering its high prevalence.

Background and Aims: Most of the evidence supporting endoscopic submucosal dissection (ESD) comes from Asia. European data are primarily reported by specialized referral centers and thus may not be representative of common European ESD practice. The aim of this study is to understand the current state of ESD practice across Italian endoscopy centers. Methods: All Italian endoscopists who were known to perform ESD were invited to complete a structured questionnaire including: operator features and competencies, ESD training details and clinical outcomes over a 2-year period. Results: Twenty-nine operators from 23 centers (69% response rate) completed the questionnaire: 18 (62%) were 150 in 8 (27.5%). Colorectal ESD was predominant for operators with an experience >80 cases. En-bloc resection rates ranged from 77.2 to 97.2% depending on the anatomic location with an R0 resection rate range of 75.3–93.6%. ESD perforation rates in the colon and rectum were significantly lower when experience was >150 compared to 80–150 cases (p < 0.0001 and p = 0.006 for colon and rectum, respectively). Conclusion: ESD in Italy is performed by a significant number of operators. Overall, Italian endoscopists performing ESD have achieved a good competence level. However, there is much variability in training protocols, initial supervision of procedures, practice settings, case mix and procedural volume/year that are likely responsible for some of the suboptimal resectional outcomes and increased perforation risk, mainly in the colon. Standardized training programs, practice parameters and auditing of outcomes are required.

The SARS-CoV-2 pandemic has changed the way we work, and health care services have to adapt. The use of personal protective equipment (PPE) and the delay of non-urgent procedures were the immediate measures adopted by Gastrointestinal (GI) Endoscopy Units at the time of crisis. As the peak has now passed in most countries, GI facilities are facing the next challenge of this pandemic: service providers must adapt their routine work to a ‘new normal’. Routine casework must resume, and waiting lists must be addressed: all in the awareness of the ongoing potential risks of COVID-19, and the threat of a second wave. In this review, we discuss strategies to manage the workload by improving procedure appropriateness and prioritization, whilst maintaining a ‘COVID-free’ environment. This includes monitoring of an adequate stock of PPE and the implications for the staff’s workload, and the GI trainees’ need of training.

Achalasia is a relatively rare primary motor esophageal disorder, characterized by absence of relaxations of the lower esophageal sphincter and of peristalsis along the esophageal body. As a result, patients typically present with dysphagia, regurgitation and occasionally chest pain, pulmonary complication and malnutrition. New diagnostic methodologies and therapeutic techniques have been recently added to the armamentarium for treating achalasia. With the aim to offer clinicians and patients an up-to-date framework for making informed decisions on the management of this disease, the International Society for Diseases of the Esophagus Guidelines proposed and endorsed the Esophageal Achalasia Guidelines (I-GOAL). The guidelines were prepared according the Appraisal of Guidelines for Research and Evaluation (AGREE-REX) tool, accredited for guideline production by NICE UK. A systematic literature search was performed and the quality of evidence and the strength of recommendations were graded according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Given the relative rarity of this disease and the paucity of high-level evidence in the literature, this process was integrated with a three-step process of anonymous voting on each statement (DELPHI). Only statements with an approval rate >80% were accepted in the guidelines. Fifty-one experts from 11 countries and 3 representatives from patient support associations participated to the preparations of the guidelines. These guidelines deal specifically with the following achalasia issues: Diagnostic workup, Definition of the disease, Severity of presentation, Medical treatment, Botulinum Toxin injection, Pneumatic dilatation, POEM, Other endoscopic treatments, Laparoscopic myotomy, Definition of recurrence, Follow up and risk of cancer, Management of end stage achalasia, Treatment options for failure, Achalasia in children, Achalasia secondary to Chagas' disease.

Background: A newly developed forward-viewing linear echoendoscope (FV-EUS) has recently become available. To date, however, only scanty data on the performance of the FV-EUS scope for fine-needle aspiration (FNA) of lesions throughout the gastrointestinal (GI) tract are available. This study aimed to evaluate the technical performance of the FV-EUS scope for FNA of solid and cystic lesions located throughout the GI tract in a large cohort of patients referred to a tertiary care center. METHODS: All patients who underwent endoscopic ultrasound (EUS)-guided FNA using the FV-EUS scope between January 2007 and December 2008 were included in this retrospective study. The performance of the FV-EUS scope for FNA was evaluated. RESULTS: During the study period, 285 patients with solid or cystic lesions throughout the GI tract underwent the procedure with the FV-EUS scope. A total of 300 FNAs were attempted, 6 (2 %) of which could not be performed. Of the 294 successful EUS-FNA procedures, 130 (44.2 %) were performed using a 22-gauge needle, 89 (30.3 %) using a 25-gauge needle, and 75 (25.5 %) using a 19-gauge needle. In all 67 cases of pancreatic cyst or dilated pancreatic duct, a specimen for cystic fluid analysis or cytologic examination could be obtained. Among the remaining 217 patients with solid lesion, a definitive diagnosis could be established for 211 patients (97.2 %). The FV-EUS scope had a sensitivity of 74.7 % (95 % confidence interval [CI] 68.1-80.6 %), a specificity of 100 % (95 % CI 89.9-100 %), a positive likelihood ratio of infinity, and a negative likelihood ratio of 0.251 (95 % CI 0.196-0.323). CONCLUSIONS: The FV-EUS scope is highly effective for FNA of solid and cystic lesions throughout the GI tract. Prospective studies comparing the FV-EUS scope and a curved linear scope are needed.

Gastroenteropancreatic neuroendocrine neoplasms have substantially increased over the last decades. Because of the indolent clinical course of the disease even in advance stages and the rise in the incidental diagnosis of small asymptomatic lesions, the prevalence of gastroenteropancreatic neuroendocrine neoplasms is higher than that of pancreatic, gastric and oesophageal adenocarcinomas, making them the second most prevalent cancer type of the gastrointestinal tract. This increase in the overall prevalence of gastroenteropancreatic neuroendocrine neoplasms has been paralleled by a growth in the importance of the endoscopist in the care of these patients, who usually require a multidisciplinary approach. In this manuscript the diagnostic and therapeutic role of endoscopic for gastroenteropancreatic neuroendocrine neoplasms will be reviewed.
