RESUMO
MR1: ESGE recommends small-bowel capsule endoscopy as the first-line examination, before consideration of other endoscopic and radiological diagnostic tests for suspected small-bowel bleeding, given the excellent safety profile of capsule endoscopy, its patient tolerability, and its potential to visualize the entire small-bowel mucosa.Strong recommendation, moderate quality evidence. MR2: ESGE recommends small-bowel capsule endoscopy in patients with overt suspected small-bowel bleeding as soon as possible after the bleeding episode, ideally within 48 hours, to maximize the diagnostic and subsequent therapeutic yield.Strong recommendation, high quality evidence. MR3: ESGE does not recommend routine second-look endoscopy prior to small-bowel capsule endoscopy in patients with suspected small-bowel bleeding or iron-deficiency anemia.Strong recommendation, low quality evidence. MR4: ESGE recommends conservative management in those patients with suspected small-bowel bleeding and high quality negative small-bowel capsule endoscopy.Strong recommendation, moderate quality evidence. MR5: ESGE recommends device-assisted enteroscopy to confirm and possibly treat lesions identified by small-bowel capsule endoscopy.Strong recommendation, high quality evidence. MR6: ESGE recommends the performance of small-bowel capsule endoscopy as a first-line examination in patients with iron-deficiency anemia when small bowel evaluation is indicated.Strong recommendation, high quality evidence. MR7: ESGE recommends small-bowel capsule endoscopy in patients with suspected Crohn's disease and negative ileocolonoscopy findings as the initial diagnostic modality for investigating the small bowel, in the absence of obstructive symptoms or known bowel stenosis.Strong recommendation, high quality evidence. MR8: ESGE recommends, in patients with unremarkable or nondiagnostic findings from dedicated small-bowel cross-sectional imaging, small-bowel capsule endoscopy as a subsequent investigation if deemed likely to influence patient management.Strong recommendation, low quality evidence. MR9: ESGE recommends, in patients with established Crohn's disease, the use of a patency capsule before small-bowel capsule endoscopy to decrease the capsule retention rate.Strong recommendation, moderate quality evidence. MR10: ESGE recommends device-assisted enteroscopy (DAE) as an alternative to surgery for foreign bodies retained in the small bowel requiring retrieval in patients without acute intestinal obstruction.Strong recommendation, moderate quality evidence. MR11: ESGE recommends DAE-endoscopic retrograde cholangiopancreatography (DAE-ERCP) as a first-line endoscopic approach to treat pancreaticobiliary diseases in patients with surgically altered anatomy (except for Billroth II patients).Strong recommendation, moderate quality evidence.

GOALS: The aim of this study was to investigate the implementation of a 14-day quadruple nonbismuth concomitant regimen, as proposed by recent Guidelines and Consensus Statements. BACKGROUND: In Greece, a region with >20% clarithromycin resistance where bismuth is unavailable, the 10-day quadruple concomitant scheme has already been adopted as the accepted first-line Helicobacter pylori eradication treatment. STUDY: Our prospective randomized study included 364 patients with newly diagnosed H. pylori infection, randomized to receive a 10-day or a 14-day nonbismuth quadruple concomitant scheme. Treatment outcome was assessed by C-urea breath test and/or histology at least 4 weeks after therapy. Intention to treat and per protocol analyses of the eradication rates were performed. Secondary endpoints included patient adherence, safety, and the impact of prior antibiotic exposure in treatment efficacy. RESULTS: The overall eradication rates of the 2 treatments were 87.9% versus 87.4% in the intention to treat analysis, P=1.000, and 93% versus 94.1%, P=0.859, in the per protocol analysis for the 10-day and the 14-day treatment group, respectively. Both groups displayed excellent compliance rates (99.5% for the 10-day vs. 96.2% for the 14-day treatment duration, P=0.067). As regards treatment safety, serious adverse events that led to the discontinuation of both regimens were few, with no statistical difference between the 2 groups (0.5% in the 10-day group and 2.2% in the 14-day group, P>0.05). Previous antibiotic exposure was not significant with regard to treatment efficacy. CONCLUSION: In Greece, the 10-day concomitant nonbismuth quadruple regimen for first-line treatment remains the most efficient strategy for H. pylori eradication.

BACKGROUND AND AIMS: Small-bowel varices (SBVs) are an uncommon consequence of portal hypertension. Radiologic intervention is usually considered for first-line management. When radiologic intervention is not possible, management options become very limited. The aim of this study was to evaluate the usefulness of double-balloon enteroscopy (DBE)-facilitated cyanoacrylate-injection endotherapy of SBVs. METHODS: This was a retrospective review of DBE-facilitated cyanoacrylate-injection endotherapy of SBVs (December 2015 to October 2016). RESULTS: Ten DBEs were performed in 6 patients (4 women; median age, 68.5 years). No radiologic or surgical options were deemed feasible. Thirteen nests of SBVs were identified and injected with cyanoacrylate glue without hemorrhagic or embolic adverse events. At the 30-day follow-up after therapy, only 1 patient had experienced a mild recurrence of mid-gut bleeding; this was managed conservatively. One patient presented with acute GI bleeding 7 months later, and a repeat DBE with cyanoacrylate-injection endotherapy was successfully performed. One patient succumbed to his underlying advanced cholangiocarcinoma after 2 months. The remaining patients had a median follow-up of 12 months without any recurrent GI bleeding. CONCLUSIONS: DBE-facilitated cyanoacrylate-injection endotherapy of SBVs appears to be a safe and effective option when other first-line options are not feasible.

BACKGROUND: Small intestinal neuroendocrine tumours (SI NETs) represent 30-50% of small bowel neoplasms and often present at an advanced stage. To date, there is relatively limited literature regarding prognostic factors affecting overall survival (OS) in stage IV disease. In addition, the prevalence of mesenteric fibrosis (MF) in SI NETs and its effect on OS have not been sufficiently explored in the literature. AIM: The primary aim of this study was to perform a large-scale survival analysis in an institutional cohort of 387 patients with metastatic (stage IV) SI NETs. The secondary aim was to provide epidemiological information regarding the prevalence of MF and to evaluate its effect on OS. RESULTS: The median OS was 101 months (95% CI 84, 118). Age > 65 years, mesenteric metastases with and without desmoplasia, liver metastases, carcinoid heart disease (CHD) and bone metastases were associated with a significantly shorter OS, while primary tumour resection was predictive of a longer OS. The benefit of surgical resection was limited to symptomatic patients. MF was present in approximately 50% of patients with mesenteric lymphadenopathy. Elevated urinary 5-HIAA levels correlated strongly with the presence of CHD (p < 0.001) and to a lesser extent (p = 0.02) with MF. MF and CHD did not usually co-exist, suggesting that different mechanisms are likely to be involved in the development of these fibrotic complications. CONCLUSIONS: This study has identified specific prognostic factors in a large cohort of 387 patients with advanced SI NETs and has provided useful epidemiological data regarding carcinoid-related fibrotic complications.

Background and study aims Full-spectrum colonoscopy (FSC) promises to increase adenoma detection by providing a wider field of view. The aim of this study was to compare adenoma miss rates of FSC with those of conventional colonoscopy complemented by right-colon re-examination using scope retroflexion (CC/R). Patients and methods At two tertiary endoscopy facilities, patients who were scheduled for colonoscopy for the assessment of symptoms or for colorectal cancer screening/surveillance were randomized (1:1) to undergo same-day, back-to-back colonoscopies (FSC or CC/R first), performed by one of five endoscopists who had documented adenoma detection rates >â35â%. Per-protocol data were analyzed. Results We randomized 220 patients. There were five FSC technical failures (three air pump and two left screen); therefore, 107 and 108 cases were analyzed in the FSC and CC/R index procedure arms, respectively. Withdrawal times were similar for FSC and CC/R (7.7 minutes vs. 7.6 minutes). Overall, we detected 3 cancers and 153 adenomas (FSCâ=â92; CC/Râ=â61); 81 were detected in the proximal colon, 3 of which were detected by retroflexed examination. By per-lesion analysis, FSC showed a significantly lower adenoma miss rate compared with CC/R overall (10.9â% [95â% confidence interval (CI) 3.8 to 18.1] vs. 33.7â% [95â%CI 23.4 to 44.1]) and in the proximal colon (13.9â% [95â%CI 2.6 to 25.2] vs. 42.2â% [95â%CI 27.8 to 56.7]). The advanced adenoma miss rate was lower with FSC overall (4.3â% [95â%CIâ-â4.0 to 12.7] vs. 25.9â% [95â%CI 9.4 to 42.5]). There were no adverse events. Conclusions FSC outperformed conventional colonoscopy with right-colon scope retroflexion in the detection of missed adenomas, both overall and in the proximal colon, even when performed by experienced endoscopists.Trial registered at ClinicalTrials.gov (NCT02117674).

OBJECTIVE: The objective of this study is to compare, in Greece, a region with >20% local resistance to clarithromycin, the efficacy rates of the concomitant versus the sequential H. pylori eradication therapy. MATERIALS AND METHODS: Our prospective randomized study included 364 patients with newly diagnosed H. pylori infection, randomized to receive a 10-day concomitant or 10-day sequential therapy. Treatment outcome was assessed by C(13)-urea breath test at least 4 weeks after therapy. Intention to treat (ITT) and per protocol (PP) analysis of the eradication rates were performed. Secondary end points included patient compliance and safety. RESULTS: The concomitant therapy group achieved statistically significant higher eradication rates when compared with the sequential treatment group, both in the ITT and in the PP analysis (84.6% versus 70.9%, p = 0.002, and 90.6% versus 78.1%, p = 0.001, respectively), after adjusting for age, gender, smoking status, and the presence or not of ulcer and/or non-ulcer dyspepsia. Both groups displayed excellent compliance rates (99.5% for the concomitant therapy group and 96.2% for the sequential therapy group, p = 0.067). Regarding treatment safety, major adverse events that led to the discontinuation of both regimens were few, with no statistical difference between the two groups (7.0% for the concomitant therapy group and 2.9% for the sequential therapy group). CONCLUSIONS: Concomitant therapy led to statistically significant higher eradication rates over sequential therapy. Both therapies showed excellent compliance and an acceptable safety profile. The 10-day quadruple concomitant scheme should be the adopted for first-line H. pylori eradication in Greece.

Small-bowel tumors represent a rare entity comprising 0.6% of all new cancer cases in the US, and only 3% of all gastrointestinal neoplasms. They are a heterogenous group of neoplasms comprising of about forty different histological subtypes with the most common being adenocarcinoma, neuroendocrine tumors, stromal tumors and lymphomas. Their incidence has been reportedly increasing over recent years, partly owing to the advances and developments in the diagnostic modalities. Small-bowel capsule endoscopy, device assisted enteroscopy and dedicated small-bowel cross-sectional imaging are complimentary tools, supplementing each other in the diagnostic process. Therapeutic management of small-bowel tumors largely depends on the histological type and staging at diagnosis. The aim of the present review article is to discuss relevant advances in the diagnosis and management of small-bowel tumors.

Air embolism (a result of direct communication with the vasculature and an external pressure gradient from the gastrointestinal or the biliary tract), although rare, is a potentially devastating adverse event seen in endoscopic retrograde cholangiopancreatography (ERCP) procedures. Whether venous, arterial, or paradoxical, the clinical presentation ranges from asymptomatic patients to cardiorespiratory arrest. This is of particular importance because it makes the diagnosis of air embolism even more difficult in an already sedated patient. Since early recognition increases the chances of patients' survival, endoscopists should be highly motivated and trained to recognize this complication as early as possible. With only 60 cases of air embolism reported (and even fewer related to paradoxical air embolism), we aimed to report a case of paradoxical cerebral air embolism in a patient undergoing ERCP due to a common bile duct stricture and to provide a mini-review of this clinical entity that can serve as a bedside quick reference guide for endoscopists worldwide.
RESUMO
The impact of small-bowel (SB) capsule endoscopy and device-assisted enteroscopy on clinical practice, since their introduction 2 decades ago, has been remarkable. These disruptive technologies have transformed the investigation and management of SB pathology and now have a firmly established place in guidelines and clinical algorithms. Furthermore, recent years have witnessed innovations, driven by the demand of new goals in the management of inflammatory bowel disease (IBD), such as mucosal healing and evolving strategies based on tight monitoring and accelerated escalation of care. These developments in SB endoscopy have also been paralleled by refinement in dedicated radiological SB imaging technologies. This updated review highlights the current state of the art and more recent innovations with a focus on their role in IBD.
RESUMO
Chronic inflammation of the intestinal mucosa has been associated with the appearance of inflammatory polyps or pseudopolyps. Among the distinct categories of inflammatory polyps are inflammatory myoglandular polyps (IMGP) usually found in the colorectum. Only one case of IMGP in the terminal ileus has been described since their first description. We report the first case of an inflammatory polyp with both hyperplastic and myoglandular histological characteristics, in the terminal ileum of a patient with quiescent Crohn's disease, causing recurrent intussusception.
RESUMO
INTRODUCTION: Cytoreductive surgery (CRS) with hyperthermal intraperitoneal chemotherapy (HIPEC) are established treatments for peritoneal carcinomatosis that prolong survival in carefully selected patients. At the time of diagnosis, 4-7% of patients with colorectal cancer (CRC) have metastasis to the peritoneum. There is a lack of evidence in the literature if J-pouch can be applied simultaneously with HIPEC to improve quality of life in patients with familial adenomatous polyposis syndrome (FAP) and peritoneal carcinomatosis. CASE PRESENTATION: We describe a case of a 41-year-old Caucasian male with Familial Adenomatous Polyposis which was diagnosed as metastatic colorectal cancer in the liver and peritoneum. He was treated with systemic chemotherapy followed by total proctocolectomy with a J-shaped IPAA, liver metastasectomy, right hemidiaphragm resection, CRS and HIPEC. DISCUSSION: CRS and HIPEC have been implicated with high morbidity and mortality rates. A major independent risk factor correlated with high morbidity is anastomotic failure. J-Pouch formation although considered a technique with high complication rates, improves the quality of life of patients after total proctocolectomy and is related to high patient satisfaction. There are inconclusive data on whether anastomotic failure rates are higher when performing J-Pouch and HIPEC together. CONCLUSIONS: J-Pouch after CRS and HIPEC can be offered as a treatment as long as the patient is carefully selected, in high volume centers with experienced surgeons.
RESUMO
BACKGROUND: Much attention has been paid to the study and reporting of gastrointestinal (GI) symptoms in COVID-19 patients. Moreover, an increasing number of COVID-19 patients have been noted to experience hepatic and pancreatic injury. In this study, we retrospectively investigated symptoms and laboratory findings related to the GI system in a single center in Athens, Greece, and assessed the role of these parameters in relation to survival and disease severity. METHOD: We retrospectively studied 61 adult COVID-19 patients admitted to the Army Share Fund Hospital (NIMTS) in Athens, Greece, from April 6th to May 6th, 2020. RESULTS: Sixty-one COVID-19 cases were assessed in the study period. Regarding both survival and disease severity, diarrhea was the most common finding. The multivariate analysis revealed that elevated serum aspartate aminotransferase levels and low serum albumin levels were associated with worse patient survival (odds ratio [OR] 1.029, 95% confidence interval [CI] 1.007-1.05, P=0.0088; and OR 0.219, 95%CI 0.066-0.723, P=0.0127, respectively). As far as disease severity is concerned, only a low serum albumin level (measured at hospital admission) was correlated with more severe disease (OR 0.025, 95%CI 0.004-0.161, P=0.0001). CONCLUSIONS: Outpatients with new-onset GI symptoms should be considered for COVID-19 testing in a high COVID-19 prevalence setting, as these symptoms are observed more and more in clinical settings. As prospective studies begin to emerge, clinicians will have more robust research data to diagnose COVID-19 patients earlier and identify patients in need of more intensive treatment.
RESUMO
The incidence of esophageal adenocarcinoma, a poor prognosis neoplasia, has risen dramatically in recent decades. Barrett's esophagus represents the best-known risk factor for esophageal adenocarcinoma development. Non-steroidal anti-inflammatory drugs through cyclooxygenase-2 inhibition and prostaglandin metabolism regulation could control cell proliferation, increase cell apoptosis and regulate the expression of growth and angiogenic factors. Statins can achieve equivalent effects through prenylation and subsequently control of cellular signaling cascades. At present, epidemiological studies are small and underpowered. Their data could not justify either medication as a chemo-preventive agent. Population based studies have shown a 43% reduction of the odds of developing an esophageal adenocarcinoma, leaving out or stating a 25% reduction in patients consuming non-aspirin nonsteroidal anti-inflammatory drugs and a 50% reduction in those patients consuming aspirin. They have also stated a 19% reduction of esophageal cancer incidence when statins have been used. Observational studies have shown that non-steroidal anti-inflammatory drugs could reduce the adenocarcinoma incidence in patients with Barrett's esophagus by 41%, while statins could reduce the risk by 43%. The cancer preventive effect has been enhanced in those patients taking a combination of non-steroidal anti-inflammatory drugs and statins (a 74% decrease). Observational data are equivocal concerning the efficacy of non-steroidal anti-inflammatory drug subclasses. Non-steroidal anti-inflammatory drugs clearly have substantial potential for toxicity, while statins are rather safe drugs. In conclusion, both non-steroidal anti-inflammatory drugs and statins are promising chemopreventive agents and deserve further exploration with interventional studies. In the meanwhile, their use is justified only in patients with cardiovascular disease.

Gastric submucosal tumors (GSMTs) are frequently found incidentally on routine upper endoscopy. Definitive diagnosis based on histological confirmation is relatively difficult. Even without accurate diagnosis before treatment, open or laparoscopic surgery is considered the standard of care for most GSMTs. Alternatively, endoscopic resection of GSMTs using different techniques has been reported in a limited number of papers. We describe a case of an antral submucosal tumor, more specifically a leiomyoma of muscularis mucosa origin, in a 78-year-old woman, that was completely resected en bloc using an endoscopic submucosal technique with a TT-knife. It is suggested that ESD is a feasible option for the diagnosis and treatment of GSTMs.
