RESUMO

BACKGROUND: Suspected small bowel bleeding (SSBB) is the main indication for videocapsule endoscopy (VCE) and double balloon enteroscopy (DBE). We assessed the impact of both modalities in a large cohort of SSBB patients in a European tertiary center. METHODS: We retrospectively evaluated consecutive patients with SSBB undergoing VCE and/or DBE from March 2001 to July 2020. Demographic/clinical parameters, anticoagulant therapies, technical characteristics and adverse events were collected, as well as diagnostic yield (DY), VCE-DBE concordance, hemoglobin (Hb) values before and after DBE, and complications. RESULTS: 807 VCEs and 407 DBEs were performed in 751 patients. The DY was significantly higher in DBE compared with VCE (68.8% vs 57.7%), with the highest (75%) yield for overt active SB bleeding. The agreement between VCE and DBE was generally suboptimal (k = 0.059). This improved in cases where both procedures were done within 1-5 days of the other (k = 0.323). Post-procedural Hb values were significantly higher. In patients treated with direct oral anticoagulants (DOACs), there were no differences in DY, complications or Hb values compared with non-DOAC patients. CONCLUSION: VCE and DBE play a pivotal role in the diagnostic and therapeutic approach to SSBB, having a high clinical impact even in patients treated with DOACs.

RESUMO

OBJECTIVE: The purpose of this study is to assess the increase both in the use of the Internet and social media and in Google searches regarding eating disorders (ED) in Italy during the Covid-19 pandemic. Our aim is also to verify the possible impact of such an increase on ED, since patients treated for ED by the National Health Service (NHS) have increased in the first 6 months of 2020 as well. METHOD: We used data from Wearesocial surveys on Internet users in the first 6 months of 2020 and the Google searches related to the query of "food disorders" and "body shaming." The first results of a project of the Italian Ministry of Health on ED have been considered too. RESULTS: The social media users in July 2020 increased to 60% of the Italian population; a tendential increase in Google searches on these issues has emerged. Finally, new patients of NHS with ED showed a high increase in the first 6 months of 2020 (+40.9%). CONCLUSION: Considering the contents diffused on the Internet, it is fundamental to watch over net usage in the adolescent population and those with ED, because massive access to social media can be considered almost as a risk factor.

RESUMO

BACKGROUND AND AIM: Small-bowel neuroendocrine neoplasm (sbNEN) diagnosis has improved with double-balloon enteroscopy (DBE). DBE efficacy in the detection of sbNENs is unknown. We aimed to report the experience at a single referral center for NENs. METHODS: All consecutive patients with a suspected sbNEN selected for diagnostic DBE were enrolled. RESULTS: Between 2011 and 2016, 25 patients were referred for a suspected sbNEN. In 15/25 patients, a primary NEN was detected outside the small bowel; in 4, NEN was excluded. After extensive workup, 6 patients (4 males, median age 50 years) underwent DBE (3 anterograde, 2 retrograde, and 1 both; median time: 60 min; median insertion 200 cm). DBE was positive in 3 patients: one had an ileal 2-cm NEN G1, one had an ileal 1.3-cm NEN G1, and one had an ileal 1-cm NEN G2, all surgically removed. Of the 3 other patients, one had a metastatic NEN of unknown primary, the other two had small intestinal NENs, both surgically removed (1.6-cm G1 and G2 NEN). DBE showed a sensitivity of 60% and, in absence of false-positive results, a specificity of 100%. Accuracy resulted 67%. No complications were observed. CONCLUSIONS: In line with data from the literature, the present series showed that DBE is a safe and effective procedure in the diagnosis of sbNENs. Further studies are needed to better clarify the diagnostic role of DBE in the neuroendocrine tumor setting and its relationship with other techniques.

RESUMO

BACKGROUND: Intestinal ultrasound (IUS) examination is a first-line non-invasive imaging procedure for patients with suspicion of bowel diseases. AIM: To assess the feasibility, reproducibility and diagnostic accuracy of a pocket-size ultrasound device (PUD) in identifying the presence of intestinal alterations in patients consecutively recruited to undergo IUS examination. METHODS: 200 consecutive patients (57% female, 48.8 years) underwent both PUD (two independent investigators) and IUS examination on the same day. Nine ultrasonographic signs were systematically searched for. PUD inter-observer reproducibility was assessed by kappa statistic and ICC. The diagnostic accuracy of PUD as compared to IUS results was assessed by calculating sensitivity, specificity and corresponding positive and negative likelihood ratios. RESULTS: PUD and IUS examinations were successful in 100% of the patients. PUD reproducibility was good/excellent at evidencing the presence (ICC 0.84) and length (ICC 0.85) of an intestinal tract with thickened wall and abdominal free fluid (ICC 0.87). The diagnostic accuracy of PUD, compared to traditional IUS, was good with regard to the presence of bowel wall thickening (sensitivity 92%, specificity 95%), the length of the thickened bowel (sensitivity 94%, specificity 95%) and the presence of free fluid (sensitivity 81%, specificity 99%). CONCLUSIONS: PUD is a feasible, reproducible and accurate first-line screening tool for the assessment of the gastro-intestinal tract.

RESUMO

Objective: The chemopreventive effect of aspirin (ASA) has been observed in the setting of colorectal cancer and other solid neoplasms. Recently, ASA has demonstrated a promising anti-proliferative effect on GEP-NENs in vitro. However, the direct anti-neoplastic impact of ASA on GEP-NEN clinical outcome is yet to be clarified. Materials and methods: All the GEP-NEN patients followed up in three European Centers from January 2005 to September 2016 were retrospectively enrolled. Patients taking ASA in doses of 75-100 mg daily for cardiovascular prevention for at least six months were evaluated. The possible association between ASA and disease grading, staging, primary site, OS and PFS were evaluated. Results: Two hundred fifty one patients were included (117 males, median age 63 years). Of these, 64 patients were prescribed with ASA. No clear impact on OS or PFS was observed in GEP-NEN patients taking ASA compared to those not taking it. ASA intake was related with the patients' older age. At Cox multivariate analysis, stage IV and Ki-67 resulted independent predictors for OS and PFS. In the setting of intestinal NENs, a suggestive, but not statistically significant, protective role of ASA on PFS was observed [HR 0.41 (95% CI: 0.13-1.29)]. Conclusions: Despite ASA showed promising anti-proliferative effects in vitro and a chemopreventive action in NENs has been reported, a clear impact of ASA on survival in NENs has not emerged from the present study. However, in the subgroup of patients with small-intestine NENs, ASA showed a trend toward a protective role.

RESUMO

AIMS: Our aim was to review the rate of biliary duct stones (BDS) after liver transplantation (LT), risk factors, and treatments, and to identify predictive factors for their onset. METHODS: LTs performed in our center from 2004 to 2014 were studied. Risk factors for the onset of BDS were identified using univariable Cox's proportional hazards models. RESULTS: Three hundred and sixty-four grafts with 317 duct-to-duct end-to-end biliary anastomosis on a T-tube and 47 hepaticojejunal anastomosis (HJ) were analyzed. BDS were identified in 13 of 364 (3.5%) grafts, including 10 duct-to-duct end-to-end biliary anastomosis on a T-tube grafts (3.2%) and 3 HJ grafts (6.4%). Predictive factors for BDS were biliary strictures (hazard ratio [HR] 9.94; 95% confidence interval [95% CI] 3.25-30.4), bilirubin (HR 1.04; 95% CI 1.01-1.06, for 1 unit increase), Model for End-Stage Liver Disease score (HR 1.07; 95% CI 1.01-1.14, for 1 unit increase), surgery time (HR 1.04; 95% CI 1.01-1.08, for 10-minute increase), hepatocellular disease (HR 8.3; 95% CI 1.09-64.0), hepatic artery thrombosis (HR 6.71; 95% CI 1.47-30.6), and retransplantation (HR 3.69; 95% CI 1.02-13.43). Among 51 grafts (14%) with biliary strictures, female sex was identified as a risk factor for BDS (HR 5.19; 95% CI 1.29-20.98). Multimodality treatment of BDS was often successful but open surgery was still needed in 23% of them. One-, 5-, and 10-year graft survival was not influenced by the onset of BDS. CONCLUSION: Main predictive factor for BDS in liver grafts is biliary stricture. Recipient's age and body mass index failed to show any statistical importance. In grafts with biliary strictures, female sex is the main risk factor for BDS. In the absence of biliary strictures, hepatic artery thrombosis lead to an increase in the risk of BDS. Multimodality treatment of BDS is often successful. BDS do not influence outcome.

RESUMO

BACKGROUND: To date no studies evaluated liver stiffness and pancreatic stiffness by shear-wave elastography, in alcoholic liver disease setting. AIMS: To assess feasibility and reproducibility of Shear-wave elastrography in measuring liver and pancreatic stiffness in alcoholic liver disease and investigate the correlation among liver and pancreatic stiffness and clinical data. METHODS: Liver and pancreatic stiffness were measured by elastography (2 examiners) in patients with alcoholic liver disease and in healthy volunteers, for reference values. Effect of clinical data was evaluated on log-transformed pancreatic or liver stiffness, using univariate and multivariate linear regression model. RESULTS: 87 patients and 46 healthy volunteers enrolled. Both the stiffness values were higher in patients than healthy volunteers (p < 0.001). For liver stiffness: no failure measurements found, the Intraclass correlation coefficient (between 2 examiners) was 0.72 and the variables significantly correlated at multivariate analysis were cirrhosis (p < 0.0001) and steatosis (p = .007). For pancreatic stiffness: 2 failures found, with ICC 0.40 and the only variable significantly correlated at multivariate analysis was liver cirrhosis (p = .005). CONCLUSIONS: Shear-wave elastography feasibility was good for liver and pancreatic stiffness. Reproducibility was good for liver stiffness, whereas fair for pancreatic one. Both the stiffness correlated with alcoholic liver disease severity. Elastography could be a useful tool to detect and monitor alcohol-related liver and pancreatic damage.

RESUMO

BACKGROUND AND AIMS: Blue-light imaging (BLI) is a new chromoendoscopy technique, potentially useful for differentiating neoplastic from nonneoplastic lesions. The present study was aimed at comparing BLI with high-definition white light (HDWL) in the real-time histology prediction of colon polyps <10 mm. METHODS: Consecutive outpatients undergoing colonoscopy with the ELUXEO 7000 endoscopy platform and 760 series video colonoscopes (Fujifilm Co, Tokyo, Japan) who had at least 1 polyp <10 mm were randomized to BLI or HDWL for polyp characterization. The accuracy of high-confidence real-time histology prediction (adenoma vs not adenoma) by either BLI or HDWL for polyps <10 mm (primary end-point) and diminutive (≤5 mm) polyps was calculated, along with sensitivity, specificity, and positive and negative predictive values, with histopathology as the reference standard. RESULTS: A total of 483 polyps were detected in 245 randomized patients (125 and 120 in the BLI and HDWL arms, respectively). A total of 358 were diminutive, and 283 were adenomas. Overall, 222 (85.7%) and 193 (86.1%) polyps were characterized with high confidence by BLI and HDWL, respectively (P = .887), with an overall accuracy of 92% and 84%, respectively (P = .011). The accuracy was significantly higher by BLI than HDWL, also for diminutive polyps (92% vs 83%; P = .008). When BLI was used, the negative predictive value for diminutive rectosigmoid polyps was 88%, and the post-polypectomy surveillance interval was correctly attributed in 85.7% and 93.7% of patients, respectively, according to U.S. and European guidelines. CONCLUSION: BLI was superior to HDWL for the real-time prediction of histology in polyps <10 mm. A BLI-dedicated classification might further improve the endoscopist performance.

RESUMO

BACKGROUND: Chronic autoimmune atrophic gastritis (CAAG) is an autoimmune disease characterized by hypo/achlorhydria. A role of CAAG in the pathogenesis of nutritional deficiencies has been reported, therefore we hypothesized a possible association between CAAG and 25-OH-Vitamin D [25(OH)D] deficiency. Aim of the present study is to evaluate the prevalence of 25(OH)D deficiency in CAAG patients. METHODS: 87 CAAG patients (71 females; mean age 63.5 ± 12.8 years) followed at our Centre from January 2012 to July 2015 were consecutively evaluated. 25(OH)D, vitamin B12, parathormone, and calcium were measured in all the CAAG patients. The results were compared with a control group of 1232 healthy subjects. RESULTS: In the CAAG group the mean 25(OH)D levels were significantly lower than in the control group (18.8 vs. 27.0 ng/ml, p < 0.0001). 25(OH)D levels < 20 ng/ml was observed in 57 patients, while levels < 12.5 ng/ml in 27 patients. A significant correlation between vitamin B12 values at diagnosis and 25(OH)D levels was observed (rs = 0.25, p = 0.01). Interestingly, the CAAG patients with moderate/severe gastric atrophy had lower 25(OH)D values as compared to those with mild atrophy (11.8 vs. 20 ng/ml; p = 0.0047). Moreover, the 25(OH)D levels were significantly lower in CAAG patients with gastric carcinoid as compared to those without gastric carcinoid (11.8 vs. 19.8 ng/ml; p = 0,0041). CONCLUSION: Data from the present study showed a significant reduction of 25(OH)D levels in CAAG patients and a possible impairment of vitamin D absorption in CAAG may be postulated. Any implication to the genesis of gastric carcinoids remains to be elucidated.

RESUMO

OBJECTIVES: Little is known about chromogranin A (CgA) during follow-up of gastroenteropancreatic neuroendocrine neoplasms. We hypothesized that serial CgA monitoring might be useful for the assessment of tumor progression, and we performed a systematic review of the literature and meta-analysis. METHODS: A bibliographical search was performed in PubMed using "chromogranin A" and "neuroendocrine tumors" and "follow-up" and "biomarker" to identify all pertinent articles published in the last 10 years. RESULTS: Eight studies were included in current meta-analysis. Chromogranin A as a follow-up marker shows sensitivity between 46% and 100% and specificity between 68% and 90%. The meta-analysis results showed an overall accuracy of 84% (95% confidence interval [CI], 81-86.6), a cumulative sensitivity of 74.6% (95% CI, 61.9-85.4), and a cumulative specificity of 84.7% (95% CI, 81.3-87.7). These data indicate that circulating CgA has a better overall accuracy in the follow-up setting; it can be used to rule the diagnosis of recurrence/progression in, rather than to rule it out. CONCLUSIONS: Chromogranin A is more reliable when used to monitor disease progression and response to treatment and for the early detection of recurrence after treatment rather than in the diagnostic setting. It is more sensible to use this marker in those cases where the initial values were impaired.

RESUMO

BACKGROUND/OBJECTIVES: The pancreatic localization of serotonin-staining neuroendocrine neoplasms is extremely rare. This is a retrospective study aimed at analyzing the endoscopic ultrasound appearance of pancreatic serotoninoma. METHODS: Between 2010 and 2016, all consecutive patients with histologically proven pancreatic serotoninoma who had undergone endoscopic ultrasound were enrolled. RESULTS: Eight patients (six F, median age 68.5 years) had a diagnosis of pancreatic serotoninoma and underwent endoscopic ultrasound examinations. Median diameter of the lesion was ten mm. The nodule echotexture was hypoechoic in seven out of eight cases. The most frequent localization was the pancreatic neck (four); in three cases, the tumor was located in the pancreatic head and in one in the body. In seven cases the tumor caused a main pancreatic duct dilation; in three cases also the secondary ducts were dilated. In one case a dilation of the common bile duct was observed. At contrast-enhanced endoscopic ultrasound no one showed the typical contrast-enhancement. Elastography (available in two patients) showed a rigid pattern of the lesion. CONCLUSIONS: From this case series a specific endoscopic ultrasound appearance resulted for pancreatic serotoninoma, different from other types of pancreatic neuroendocrine neoplasm, but it is difficult to differentiate it from a pancreatic adenocarcinoma or an intraductal papillary mucinous neoplasm.

RESUMO

The ingestion of gluten has been associated with gastrointestinal symptoms even in the absence of detectable immune responses. Little is known about the pathophysiological effects of gluten on the upper gastrointestinal tract. We aimed to assess whether the ingestion of gluten leads to an impairment of the physiological mechanisms of gastric emptying, gallbladder contraction and relaxation. A total of 17 healthy subjects underwent ultrasound evaluation of gastric emptying dynamics and gallbladder contractions at baseline and every 30 min after a standard gluten-containing and gluten-free meal (250 kcal, 70% carbohydrates). The pattern of gastric emptying was similar after a standard meal with or without gluten, but differed in terms of the peak of the antral filling curve, which was wider (mean area 5.69, median 4.70, range 3.71‒9.27 cm² vs. mean 4.89, median 4.57, 2.27‒10.22 cm², p = 0.023) after the gluten-containing meal. The pattern of gallbladder contractions was different after the gluten-free meal (p < 0.05), with higher gallbladder volumes in the late refilling phases. The results of this study show that gluten ingestion exerts objective effects on gastric and gallbladder motility. Although the underlying pathophysiological mechanism remains unknown, these results could account for some of the gluten-related symptoms reported by patients with celiac disease and non-celiac gluten sensitivity.

RESUMO

BACKGROUND: The optimal management of duodenal neuroendocrine neoplasms (dNENs) is unclear, and endoscopic resection is increasingly performed instead of surgery. METHODS: This is a retrospective analysis of patients with histologically confirmed diagnosis of dNENs, managed at five Italian tertiary referral Centers in Italy. RESULTS: From 2000 to 2017, 108 patients (69 males, 39 females, median age 59.5 years) were included in this study. Seventy-one patients had G1, 21 G2, 4 G3 dNENs (12 Ki-67 not available). Fifty-four patients showed metastases at diagnosis, and 20 patients developed metachronous metastases. Thirty patients had a functioning dNEN (14 metastatic). Fifty-seven patients had the dNEN surgically resected, 16 endoscopically, 23 metastatic, received medical therapy + surgery or endoscopy. Seven patients underwent liver-directed therapies, and one patient had PRRT. Median OS was 187 months. During a median follow-up of 76 months, 20 patients died (19 of disease-related causes). At Cox's multivariate proportional hazard regression, grading and age were the only variables independently related to OS. Median PFS was 170 months. Grading and staging at the initial diagnosis were independently related to PFS. No differences in terms of OS and PFS were observed between patients treated surgically or endoscopically. CONCLUSIONS: dNENs prognosis may be highly variable. These tumors can be metastatic in up to 50% of cases at the time of first diagnosis and can develop metastases thereafter. Functioning neoplasms express high metastatic potential. Nuclear imaging should be performed to exclude distant metastases in all dNENs. Endoscopy and surgery play a primary role in the management of the disease. Further prospective studies are needed.

RESUMO

BACKGROUND: Duodenal neuroendocrine neoplasms (dNENs) are rare tumors, which usually show good prognosis. The optimal management of these tumors is still far from being clearly understood because of their rarity and the poor level of knowledge about their natural history. Herein, we have reviewed the literature on dNENs to collect and analyze the current data on epidemiology, diagnosis and management of these rare tumors. METHODS: Bibliographical searches were performed in PubMed, using the following keywords: duodenal neuroendocrine neoplasm; duodenum; gastrinoma; diagnosis; therapy; guidelines. We searched for all relevant articles published over the last 15 years. Non-English language papers were excluded. RESULTS: We reviewed the pertinent articles about dNENs. Upper gastrointestinal endoscopy with biopsy is the cornerstone of the dNENs diagnostic process. Endoscopic ultrasound with fine-needle aspiration/biopsy should be performed in order to locally stage the disease and in all cases of non-diagnostic endoscopy. Endoscopic or complete surgical removal of the primary lesion is the recommended treatment and is generally achievable for the majority of the patients. A less aggressive approach may be suggested for well-differentiated low-stage tumors. After NEN removal, patients should be closely followed-up especially during the first 3 years by endoscopic examination, imaging tests and CgA measurements. CONCLUSIONS: The multi-disciplinary approach and the preservation of the quality of life of the patients play a key role in the therapeutic process for dNENs. Further studies are needed to better define standardized guidelines specific to dNENs, including optimal management approaches and follow-up intervals.

RESUMO

OBJECTIVES: Studies investigating patients with coeliac disease (CD) on very long-term follow-up are limited. We aimed to evaluate the characteristics of patients with CD diagnosed more than 30 years ago. METHODS: Clinical, histologic, genetic, and demographic data of patients with CD diagnosis made before 1985 were collected and their standardised mortality ratio calculated. According to the gluten-free diet (GFD) status, CD patients were divided into 3 groups and a specific questionnaire on GFD awareness and gluten-free products was administered to patients and caregivers. RESULTS: A total of 337 CD patients were included in the study. The standardised mortality ratio was 0.37 (confidence interval 0.10 to 0.94) compared with a matched population. A total of 197 patients were grouped according to GFD compliance, with 35 CD patients reporting chronic voluntary gluten ingestion. No significant differences were found between groups regarding family history of CD, symptoms and histology at diagnosis, autoimmune disorders. Follow-up histology was performed in 63 patients. Twenty patients had normal histology on gluten-containing diet (GCD). Questionnaire scores were lower in patients on GCD. Caregivers scores were not correlated with patients' gluten consumption. CONCLUSIONS: Although poor adherence to GFD is the major predictor of persistence of mucosal lesions at follow-up histology, a proportion of patients did not show a relapse of villous atrophy in spite chronic voluntary gluten ingestion, nor increase in mortality. Moreover, GFD knowledge and adherence could be partly lost during the transition between childhood and adulthood.

RESUMO

BACKGROUND: Linked color imaging (LCI) is a newly developed image-enhancing endoscopy technology that provides bright endoscopic images and increases color contrast. We investigated whether LCI improves the detection of neoplastic lesions in the right colon when compared with high definition white-light imaging (WLI). METHODS: Consecutive patients undergoing colonoscopy were randomized (1:1) after cecal intubation into right colon inspection at first pass by LCI or by WLI. At the hepatic flexure, the scope was reintroduced to the cecum under LCI and a second right colon inspection was performed under WLI in previously LCI-scoped patients (LCI-WLI group) and vice versa (WLI-LCI group). Lesions detected on first- and second-pass examinations were used to calculate detection and miss rates, respectively. The primary outcome was the right colon adenoma miss rate. RESULTS: Of the 600 patients enrolled, 142 had at least one adenoma in the right colon, with similar right colon adenoma detection rates (r-ADR) in the two groups (22.7 % in LCI-WLI and 24.7 % in WLI-LCI). At per-polyp analysis, double inspection of the right colon in the LCI-WLI and WLI-LCI groups resulted in an 11.8 % and 30.6 % adenoma miss rate, respectively (P < 0.001). No significant difference in miss rate was found for advanced adenomas or sessile serrated lesions. At per-patient analysis, at least one adenoma was identified in the second pass only (incremental ADR) in 2 of 300 patients (0.7 %) in the LCI - WLI group and in 13 of 300 patients (4.3 %) in the WLI - LCI group (P = 0.01). CONCLUSIONS: LCI could reduce the miss rate of neoplastic lesions in the right colon.

RESUMO

Gallium-68 DOTA-peptide positron emission tomography/computed tomography (68Ga-PET/CT) has emerged as a promising tool for the diagnosis and staging of gastro-entero-pancreatic neoplasms, thanks to its high sensitivity and specificity. Heterotopic pancreas, which is relatively rare, has never been reported as a possible cause of false positives of 68Ga-PET/CT. We report on the first case of a heterotopic pancreas showing pathological uptake at 68Ga-PET/CT, thus mimicking an intestinal neuroendocrine tumor. The present case suggests that heterotopic pancreas should be included among the possible causes of false positives at 68Ga PET.
