Knowledge on the role of Helicobacter pylori (HP) infection is continually evolving, and treatment is becoming more challenging due to increasing bacterial resistance. Since the management of HP infection is changing, an update of the national Italian guidelines delivered in 2007 was needed. In the III Working Group Consensus Report 2015, a panel of 17 experts from several Italian regions reviewed current evidence on different topics relating to HP infection. Four working groups examined the following topics: (1) "open questions" on HP diagnosis and treatment (focusing on dyspepsia, gastro-oesophageal reflux disease, non-steroidal anti-inflammatory drugs or aspirin use and extra-gastric diseases); (2) non-invasive and invasive diagnostic tests; (3) treatment of HP infection; (4) role of HP in the prevention of gastric cancer. Statements and recommendations were discussed and a consensus reached in a final plenary session held in February 2015 in Bologna. Recommendations are based on the best current evidence to help physicians manage HP infection in Italy. The guidelines have been endorsed by the Italian Society of Gastroenterology and the Italian Society of Digestive Endoscopy., (Copyright © 2015 Editrice Gastroenterologica Italiana S.r.l.

Background and Aim: Few studies have specifically addressed interobserver agreement in describing lesions identified during capsule endoscopy. The aim of our study is to evaluate interobserver agreement in the description of capsule endoscopy findings., Materials and Methods: Consecutive short segments of capsule endoscopy were prospectively observed by 8 investigators. Seventy-five videos were prepared by an external investigator (gold standard). The description of the findings was reported by the investigators using the same validated and standardized capsule endoscopy structured terminology. The agreement was assessed using Cohen's kappa statistic., Results: As concerns the ability to detect a lesion, the agreement with the gold standard was moderate (kappa 0.48), as well as the agreement relating to the final diagnosis (κ 0.45). The best agreement was observed in identifying the presence of active bleeding (κ 0.72), whereas the poorest agreement concerned the lesion size (κ 0.32). The agreement with the GS was significantly better in endoscopists with higher case/volume of capsule endoscopy per year. Diagnostic concordance was better in the presence of angiectasia than in the presence of polyps or ulcers/erosions., Conclusions: Correct lesion identification and diagnosis seem more likely to occur in presence of angiectasia, and for readers with more experience in capsule endoscopy reading., (Published by Elsevier Ltd.)

We report two unusual cases of occult intestinal bleeding due to lipoma of the small bowel. Both the patients underwent several inconclusive endoscopic and radiological procedures before the diagnosis of these lesions that was possible using video capsule endoscopy and double balloon enteroscopy. In the first case, the finding of capsule endoscopy was confirmed using enteroscopy, allowing us to diagnose the ileal mass. In the second and more recent case, we used double balloon enteroscopy for the further characterisation and management of the ileal lipoma. Lipoma is a very rare cause of intestinal bleeding and we describe the management and the outcome of our patients.

Background and Aims: The province of Ferrara has one of the highest incidences of colorectal cancer (CRC) in Italy. In January 2000, we set up a colonoscopy screening program focussing on first-degree relatives of CRC patients. We now report the results 5 years after the beginning of the project. SCREENEES AND METHODS: In October 1999, we started a campaign stressing the usefulness of colonoscopy for the first-degree relatives of CRC patients. Subjects included in the screening program were aged between 45 and 75 years with at least one first-degree relative affected by CRC. They were invited to an interview where a physician suggested colonoscopy as a screening option., Results: In 5 years, 776 subjects were interviewed and 733 (94.4%) agreed to an endoscopic examination (M/F:375/401; mean age 55 years): 562 colonoscopies were performed. Adenomas and cancers were found in 122 (21.7%) and 12 (2.1%) subjects, respectively. Histological examination in 181 persons with lesions (32.8%) showed (most serious lesion quoted) 47 hyperplastic polyps (26% of all lesions), 2 serrated adenomas (1.1%), 68 tubular adenomas (48%), 24 tubulovillous adenomas (13.3%), 9 adenomas with high grade dysplasia (5%) and 12 adenocarcinomas (6.6%). The majority of the cancers were at an early stage (8 Dukes A and 3 Dukes B). Sedation was used in only 42 colonoscopies (7.5%)., Conclusions: A colonoscopy-based screening in this selected high-risk population is feasible. Even without sedation subjects readily agreed to the endoscopic procedure. We identified a significant number of advanced neoplasms and cancers at an early stage suggesting that this could be a useful tool in early identification of CRC.

Biliary sludge is a mixture of particulate matter which has precipitated from bile. It generally consists of cholesterol monohydrate crystals, calcium bilirubinate or other calcium salts. In a clinical setting, biliary sludge is almost always an ultrasonographic diagnosis. Although it is less clinically applicable, direct microscopic examination of gallbladder bile is far more sensitive than ultrasonography into sludge detection, and has to be regarded as the diagnostic gold standard. The overall prevalence of sludge in the general population is relatively low. However, several clinical conditions are associated with a particularly high prevalence of biliary sludge, including pregnancy, rapid weight loss, total parenteral nutrition, octreotide therapy, bone marrow or solid organ transplantation. The clinical course of biliary sludge varies, and complete resolution, a waxing and waning course, and progression to gallstones are all possible outcomes. It may cause complications usually associated with gallstones, such as biliary colic, acute cholecystitis, and acute pancreatitis. The main pathogenic mechanism involved in sludge formation is probably gallbladder dismotility, and in selected patients measures aimed to maintain adequate gallbladder contractions has been shown to effectively prevent sludge development.

The case of a 22-year-old male who bled from a Meckel's diverticulum is described. The diagnosis was achieved after 99mTechnetium pertechnetate scintigraphy. With the administration of somatostatin very clear images were obtained. The histological examination confirmed the presence of ectopic gastric mucosa. The literature, over the last 10 years, has been reviewed to identify factors associated with bleeding in adults. Ectopic gastric mucosa is the most important factor predicting bleeding. The diagnostic approach to bleeding Meckel's diverticulum and the improvement in the quality of 99mTechnetium pertechnetate scintigraphy, following administration of somatostatin, is discussed.
