RESUMO
BACKGROUND: First-line over-the-scope (OTS) clip treatment has shown higher efficacy than standard endoscopic therapy in acute nonvariceal upper gastrointestinal bleeding (NVUGIB) from different causes. We compared OTS clips with through-the-scope (TTS) clips as first-line mechanical treatment in the specific setting of peptic ulcer bleeding. METHODS: We conducted an international, multicenter randomized controlled trial on consecutive patients with suspected NVUGIB. Patients with Forrest Ia-IIb gastroduodenal peptic ulcer were randomized 1:1 to OTS clip or TTS clip treatment. The primary outcome was the rate of 30-day rebleeding after successful initial hemostasis. Secondary outcomes included the rates of successful initial hemostasis and overall clinical success, defined as the composite of successful initial hemostasis and no evidence of 30-day rebleeding. RESULTS: 251 patients were screened and 112 patients were randomized to OTS (n = 61) or TTS (n = 51) clip treatment. The 30-day rebleeding rates were 1.6% (1/61) and 3.9% (2/51) in patients treated with OTS clips and TTS clips, respectively (Kaplan-Meier log-rank, P = 0.46). Successful initial hemostasis rates were 98.4% (60/61) in the OTS clip group and 78.4% (40/51) in the TTS clip group (P = 0.001). Overall clinical success rates were 96.7% (59/61) with OTS clips and 74.5% (38/51) with TTS clips (P = 0.001). CONCLUSIONS: Low rates of 30-day rebleeding were observed after first-line endoscopic treatment of acute peptic ulcer bleeding with either OTS or TTS clips. However, OTS clips showed higher efficacy than TTS clips in achieving successful initial hemostasis and overall clinical success.
RESUMO
BACKGROUND: The Endocuff Vision device (Arc Medical Design Ltd., Leeds, UK) has been shown to increase mucosal exposure, and consequently adenoma detection rate (ADR), during colonoscopy. This nationwide multicenter study assessed possible benefits and harms of using Endocuff Vision in a fecal immunochemical test (FIT)-based screening program. METHODS: Patients undergoing colonoscopy after a FIT-positive test were randomized 1:1 to undergo Endocuff-assisted colonoscopy or standard colonoscopy, stratified by sex, age, and screening history. Primary outcome was ADR. Secondary outcomes were ADR stratified by endoscopists' ADR, advanced ADR (AADR), adenomas per colonoscopy (APC), withdrawal time, and adverse events. RESULTS: 1866 patients were enrolled across 13 centers. After exclusions, 1813 (mean age 60.1 years; male 53.8â%) were randomized (908 Endocuff Vision, 905 standard colonoscopy). ADR was significantly higher in the Endocuff Vision arm (47.8â% vs. 40.8â%; relative risk [RR] 1.17, 95â% confidence interval [CI] 1.06-1.30), with no differences between arms regarding size or morphology. When stratifying for endoscopists' ADR, only low detectors (ADRâ<â33.3â%) showed a statistically significant ADR increase (Endocuff Vision 41.1â% [95â%CI 35.7-46.7] vs. standard colonoscopy 26.0â% [95â%CI 21.3-31.4]). AADR (24.8â% vs. 20.5â%, RR 1.21, 95â%CI 1.02-1.43) and APC (0.94 vs. 0.77; P â=â0.001) were higher in the Endocuff Vision arm. Withdrawal time and adverse events were similar between arms. CONCLUSION: Endocuff Vision increased ADR in a FIT-based screening program by improving examination of the whole colonic mucosa. Utility was highest among endoscopists with a low ADR.

GOALS: The present survey from the Italian Society of Digestive Endoscopy (SIED-Società Italiana di Endoscopia Digestiva) was aimed at reporting infection control practice and outcomes at Digestive Endoscopy Units in a high-incidence area. BACKGROUND: Lombardy was the Italian region with the highest coronavirus disease-2019 (COVID-19) prevalence, at the end of March 2020 accounting for 20% of all worldwide deaths. Joint Gastro-Intestinal societies released recommendations for Endoscopy Units to reduce the risk of the contagion. However, there are few data from high-prevalence areas on adherence to these recommendations and on their efficacy. METHODS: A survey was designed by the Lombardy section of SIED to analyze (a) changes in activity and organization, (b) adherence to recommendations, (c) rate of health care professionals' (HCP) infection during the COVID-19 outbreak. RESULTS: In total, 35/61 invited centers (57.4%) participated; most modified activities were according to recommendations and had filtering face piece 2/filtering face piece 3 and water-repellent gowns available, but few had negative-pressure rooms or provided telephonic follow-up; 15% of HCPs called in sick and 6% had confirmed COVID-19. There was a trend (P=0.07) toward different confirmed COVID-19 rates among endoscopists (7.9%), nurses (6.6%), intermediate-care technicians (3.4%), and administrative personnel (2.2%). There was no correlation between the rate of sick HCPs and COVID-19 incidence in the provinces and personal protective equipment availability and use, whereas an inverse correlation with hospital volume was found. CONCLUSIONS: Adherence to recommendations was rather good, though a minority were able to follow all recommendations. Confirmed COVID-19 seemed higher among endoscopists and nurses, suggesting that activities in the endoscopy rooms are at considerable viral spread risk.

BACKGROUND: COVID-19 pandemic has impacted the Italian National Health Care system at many different levels, causing a complete reorganization of surgical wards. In this context, our study retrospectively analysed the management strategy for patients with acute cholecystitis. METHODS: We analysed all patients admitted to our Emergency Department for acute cholecystitis between February and April 2020 and we graded each case according to 2018 Tokyo Guidelines. All patients were tested for positivity to SARS-CoV-2 and received an initial conservative treatment. We focused on patients submitted to cholecystostomy during the acute phase of pandemic and their subsequent disease evolution. RESULTS: Thirty-seven patients were admitted for acute cholecystitis (13 grade I, 16 grade II, 8 grade III). According to Tokyo Guidelines (2018), patients were successfully treated with antibiotic only, bedside percutaneous transhepatic gallbladder drainage (PC) and laparoscopic cholecystectomy (LC) in 29.7%, 21.6% and 48.7% of cases respectively. Therapeutic strategy of three out of 8 cases, otherwise fit for surgery, submitted to bedside percutaneous transhepatic gallbladder drainage (37.5%), were directly modified by COVID-19 pandemic: one due to the SARS-CoV-2 positivity, while two others due to unavailability of operating room and intensive care unit for post-operative monitoring respectively. Overall success rate of percutaneous cholecystostomy was of 87.5%. The mean post-procedural hospitalization length was 9 days, and no related adverse events were observed apart from transient parietal bleeding, conservatively treated. Once discharged, two patients required readmission because of acute biliary symptoms. Median time of drainage removal was 43 days and only 50% patients thereafter underwent cholecystectomy. CONCLUSIONS: Percutaneous cholecystostomy has shown to be an effective and safe treatment thus acquiring an increased relevance in the first phase of the pandemic. Nowadays, considering we are forced to live with the SARS-CoV-2 virus, PC should be considered as a virtuous, alternative tool for potentially all COVID-19 positive patients and selectively for negative cases unresponsive to conservative therapy and unfit for surgery.

Background and Objective: Pediatric guidelines on celiac disease (CD) state that children with anti-transglutaminase antibodies (TGAs) >×10 upper limit of normal (ULN) may avoid endoscopy and biopsy. We aimed to evaluate whether these criteria may be suitable for villous atrophy diagnosis in CD adults. Materials and Methods: We retrospectively enrolled patients with CD aged >18 years. TGAs were expressed as xULN. Duodenal lesions were classified as atrophic or non-atrophic according to Marsh-Oberhuber. Fisher's exact and t-test were used for variables comparison. Receiver operating characteristics (ROC) curve analysis was performed with estimation of area under the curve (AUC), sensitivity, specificity, and positive and negative predictive value (PPV/NPV). Results: One hundred and twenty-one patients were recruited. Sixty patients (49.6%) had TGA >×10 ULN, and 93 (76.8%) had villous atrophy. The cut-off of >×10 ULN had sensitivity = 53.7%, specificity = 64.3%, PPV = 83.3%, and NPV = 29.5% to predict atrophy. Therefore, considering pediatric criteria, in 50 (41.3%) patients, biopsy could have been avoided. Patient subgroup with atrophy had higher TGA levels despite being not significant (37.2 ± 15.3 vs. 8.0 ± 1.3 ULN, p = 0.06). In adults, a slightly better diagnostic performance was obtained using a cut-off of TGA >×6.2 ULN (sensitivity = 57.1%, specificity = 65.6%, and AUC = 0.62). Conclusions: Despite our confirmation that villous atrophy is linked to high TGA levels, CD and atrophy diagnosis based only on serology is not reliable in adults.

OBJECTIVE. The purpose of this study was to evaluate the accuracy of CT colonography (CTC) in the diagnosis of synchronous colonic lesions in a cohort of patients with an occlusive colorectal cancer (CRC) causing incomplete colonoscopy. SUBJECTS AND METHODS. Among 109 patients with CRC causing incomplete colonoscopy who underwent CTC with IV contrast enhancement after cathartic purgation, fecal tagging, and colon distention, 70 (mean age, 70 years) for whom reference standards (surgical reports, first surveillance colonoscopy) were available were evaluated. Per-patient and per-lesion sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) of CTC in the diagnosis of synchronous colonic lesions measuring 6 mm or larger were assessed. RESULTS. Twenty-seven of the 70 patients (39%) had at least one 6-mm or larger synchronous lesion, and four patients (6%) had a total of five synchronous CRCs. Per-patient sensitivity in diagnosing synchronous CRC was 1.00 (4/4). There were 59 lesions: 20 with a diameter of 10 mm or greater; 30, 6-9 mm; and nine, 5 mm or less. The overall per-patient CTC sensitivity in detecting synchronous lesions 6 mm or larger was 0.93 (25/27); specificity, 0.98 (42/43); PPV, 0.96; and NPV, 0.95. Per-patient sensitivity for the diagnosis of synchronous advanced neoplasia (advanced adenoma and colorectal cancers) was 0.94 (15/16). Per-lesion CTC sensitivity for detecting synchronous lesions 6 mm or larger was 0.88 (37/42); all adenomatous lesions, 0.89 (55/62); and advanced neoplasia, 0.92 (22/24). CONCLUSION. CTC is a highly accurate test for detecting synchronous colonic lesions in patients with occlusive CRC. The prevalence of advanced neoplasia is high (23%).

BACKGROUND AND AIMS: There are 2 techniques described for selective bile duct guidewire cannulation, the touch (T) technique (engaging the papilla with a sphincterotome and then advancing the guidewire) and the no-touch (NT) technique (engaging the papilla only with the guidewire). The aim of this prospective, multicenter randomized study was to compare the outcomes of the 2 guidewire cannulation techniques. METHODS: Three hundred consecutive patients with naïve papillae were enrolled in 2 groups (150 to T group and 150 to NT group). A maximum of 15 biliary cannulation attempts, for no longer than 5 minutes, or a maximum of 5 unintentional cannulations of the pancreatic duct for each group were performed. If biliary cannulation failed, the patient was crossed over to the other technique with the same parameters. The primary outcome was the guidewire cannulation success rate using either the T or NT technique. Secondary outcomes were the number of attempts and cannulation duration, number of pancreatic duct cannulations, and adverse events. RESULTS: The primary cannulation rate was significantly higher in the T group compared with the NT group (88% vs 54%, P < .001), and the cannulation rate was significantly higher using the T technique compared with the NT technique also after crossover (77% vs 17%, P < .001). The mean number of cannulation attempts was 4.6 in the T group versus 5.5 in the NT group (P = .006), and the duration of cannulation before crossover (P < .001) and overall cannulation duration after crossover (P < .001) were significantly lower in the T group. The number of unintended pancreatic duct cannulations was statistically higher using the T technique compared with the NT technique (P = .037). The rates of adverse events did not significantly differ between the 2 groups. CONCLUSIONS: Our results clearly indicated that the T technique is superior to the NT technique for biliary cannulation.

BACKGROUND: Early detection of small pancreatic cancer is important because expected survival is markedly better for tumors ≤ 2 cm. A new endoscopic ultrasound-(EUS) guided biopsy needle with side fenestration has been recently developed to enable fine-needle biopsy (FNB) under EUS guidance. The aim of this study was to evaluate the outcome of EUS-FNB using a 22-gauge ProCore needle in solid pancreatic lesions ≤ 2 cm, in terms of diagnostic accuracy and yield. METHODS: From January 2011 to December 2012, all consecutive EUS-guided tissue sampling of small pancreatic lesions (≤ 2 cm) were performed using 22-gauge ProCore needles; the data of these patients were analyzed retrospectively. RESULTS: Sixty-eight patients with a mean age of 65.7 years were included. The mean lesion size was 16.5 mm (range 5-20). None of the patients developed complications. On pathological examination, the tissue retrieved was judged adequate in 58 out of 68 cases (85.3 %) and the presence of a tissue core was recorded in 36 out of 68 cases (52.9 %). The overall sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 80, 100, 100, 40, and 82 %, respectively. CONCLUSION: Our results suggested that EUS-FNB of small pancreatic lesions using a 22-gauge ProCore needle is effective and safe, and supports our hypothesis that EUS-FNB is highly useful in establishing the nature of small pancreatic lesions.

INTRODUCTION: Impairment of the gastrointestinal barrier leads to microbial translocation and peripheral immune activation, which are linked to disease progression. Data in the setting of primary HIV/SIV infection suggest that gut barrier damage is one of the first events of the pathogenic cascade, preceding mucosal immune dysfunction and microbial translocation. We assessed gut structure and immunity as well as microbial translocation in acutely and chronically-infected, combination antiretroviral therapy (cART)-naive individuals. METHODS: Fifteen people with primary HIV infection (P-HIV) and 13 with chronic HIV infection (C-HIV) c-ART-naive participants were cross-sectionally studied. Gut biopsies were analysed in terms of gut reservoirs (total, integrated and unintegrated HIV DNA); tight junction proteins (E-cadherin, Zonula Occludens-1), CD4 + expression, neutrophil myeloperoxidase (histochemical staining); collagen deposition (Masson staining). Flow cytometry was used to assess γδ T-cell frequency (CD3 + panγδ+Vδ1+/Vδ2+). In plasma, we measured microbial translocation (LPS, sCD14, EndoCAb) and gut barrier function (I-FABP) markers (ELISA). RESULTS: P-HIV displayed significantly higher tissue HIV DNA, yet neutrophil infiltration and collagen deposition in the gut were similar in the two groups. In contrast, microbial translocation markers were significantly lower in P-HIV compared with C-HIV. A trend to higher mucosal E-cadherin, and gut γδ T-cells was also observed in P-HIV. CONCLUSION: Early HIV infection features higher HIV DNA in the gut, yet comparable mucosal alterations to those observed in chronic infection. In contrast, microbial translocation is contained in primary HIV infection, likely because of a partial preservation of E-cadherin and mucosal immune subsets, namely γδ T-cells.

PURPOSE: Surgical decompression is the traditional treatment for acute colorectal cancer obstruction. In recent years, colorectal stenting has been used to relieve the obstruction. This study used meta-analytic techniques to compare colonic stenting versus surgical decompression for colorectal cancer obstruction. METHODS: A comprehensive search of several databases was conducted. The search identified 321 potential abstracts and titles of which eight randomized trials involving 353 patients were retrieved in full text. A meta-analysis of the studies included was carried out to identify the differences in outcomes between the two procedures. RESULTS: The pooled analysis showed no significant differences for mortality (odds ratio (OR) 0.91) and morbidity (OR 2.05) rates between the two strategies while the permanent stoma creation rate was significantly higher in the surgical group as compared to the stent group (OR 3.12). By comparing surgery and colonic stenting in studies which analyzed the use of stenting as a "bridge to surgery," the pooled analysis showed that primary anastomosis was more frequent in the stent group as compared to the surgical group (OR 0.42), and the stoma creation was more frequent in the surgical group as compared to the stent group (OR 2.36). CONCLUSION: Our study suggested that, in patients with acute colorectal cancer obstruction, stent placement improved several outcomes, such as primary anastomosis, stoma formation, and permanent stoma, while it failed to show an improvement in mortality and morbidity risk.

Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are rare tumors derived from the neuroendocrine cell system, which that have increased in incidence and prevalence in recent years. Despite improvements in radiological and metabolic imaging, endoscopy still plays a pivotal role in the number of GEP-NENs. Tumor detection, characterization, and staging are essential in management and treatment planning. Upper and lower gastrointestinal (GI) endoscopy is essential for correct localization of the primary tumor site of GI NENs. Endoscopic ultrasonography (EUS) has an important role in the imaging and tissue acquisition of pancreatic NENs and locoregional staging of GI neuroendocrine tumors. Correct staging and histological diagnosis have important prognostic implications. Endoscopic operating techniques allow the removal of small GI NENs in the early stage of mucosal or submucosal invasion of the intestinal wall. Preoperative EUS-guided techniques may help the surgeon locate small and deep tumors, thus avoiding formal pancreatic resections in favor of parenchymal-sparing surgery. Finally, locoregional ablative treatments have been proposed in recent studies with promising results in selected patients.

OBJECTIVE: The aim of this study was to evaluate the outcomes of through-the-scope (TTS) large diameter self-expanding metal stent (SEMS) placement for palliation of malignant colorectal obstruction. MATERIAL AND METHODS: Between January 2005 and December 2009, all patients who underwent endoscopic SEMS placement for palliation of malignant colorectal obstruction were prospectively enrolled. RESULTS: Thirty-nine patients (17M and 22F; mean age 75.9 ± 10.6 years, range 50-91) were enrolled. The most frequent location was the sigmoid colon (13 cases). The causes of obstruction were colorectal malignancy in 32 patients and extracolonic malignancy in 7. Technical success was achieved in 36/39 patients (92.3%) and clinical success in 35/39 patients (89.7%). Technical failure was related to female sex (p = 0.04) and the extracolonic etiology of the stricture (p < 0.001). There were three early complications: two procedure-related perforations successfully managed conservatively and one hemorrhage treated with APC. Early complications were related to the location of strictures at the recto-sigmoid junction (p < 0.001). Late complications occurred in 10 patients: 8 of these patients experienced occlusive symptoms (attributable to tumor ingrowth in 5 cases and stool impaction in 3 cases); the remaining 2 were one case of tumor ingrowth with sub-occlusive symptoms and hemorrhage, and one case of distal migration. There was no procedure-related mortality and all complications were managed without surgical intervention. SEMS patency duration was 236 ± 128 days (range 31-497) and mean survival of the patients was 259 ± 121 days (range, 32-511). CONCLUSIONS: In our experience, TTS large-diameter SEMS placement is a safe and effective treatment for palliation of malignant colorectal obstruction.

The diagnosis of coeliac disease (CD) in adult patients requires the simultaneous assessment of clinical presentation, serology, and typical histological picture of villous atrophy. However, several years ago, the European Society of Pediatric Gastroenterology, Hepatology, and Nutrition guidelines approved new criteria for the diagnosis in children: Biopsy could be avoided when anti-transglutaminase antibody (TGA) values exceed the cut-off of × 10 upper limit of normal (ULN) and anti-endomysium antibodies are positive, independently from value. This "no biopsy" approach is a decisive need for pediatric population, allowing to avoid stressful endoscopic procedures in children, if unnecessary. This approach relies on the correlation existing in children between TGA levels and assessment of mucosal atrophy according to Marsh's classification. Several lines of evidence have shown that patients with villous atrophy have markedly elevated TGA levels. Therefore, we aim to perform a narrative review on the topic in adults. Despite that some studies confirmed that the × 10 ULN threshold value has a very good diagnostic performance, several lines of evidence in adults suggest that TGA cut off should be different from that of pediatric population for reaching a good correlation with histological picture. In conclusion, the heterogeneity of study reports as well as some conditions, which may hamper the serological diagnosis of CD (such as seronegative CD and non-celiac villous atrophy) and are much more common in adults than in children, could represent a limitation for the "no biopsy" approach to CD diagnosis in patients outside the pediatric age.

The incidence of colorectal cancer (CRC) is characterized by rapid declines in the wake of widespread screening. Colonoscopy is the gold standard for CRC screening, but its accuracy is related to high quality of bowel preparation (BP). In this review, we aimed to summarized the current strategy to increase bowel cleansing before colonoscopy. Newly bowel cleansing agents were developed with the same efficacy of previous agent but requiring less amount of liquid to improve patients' acceptability. The role of the diet before colonoscopy was also changed, as well the contribution of educational intervention and the use of adjunctive drugs to improve patients' tolerance and/or quality of BP. The review also described BP in special situations, as lower gastrointestinal bleeding, elderly people, patients with chronic kidney disease, patients with inflammatory bowel disease, patients with congestive heart failure, inpatient, patient with previous bowel resection, pregnant/lactating patients. The review underlined the quality of BP should be described using a validate scale in colonoscopy report and it explored the available scales. Finally, the review explored the possible contribution of bowel cleansing in post-colonoscopy syndrome that can be related by a transient alteration of gut microbiota. Moreover, the study underlined several points needed to further investigations.

BACKGROUND: Leaks are the major complication associated with laparoscopic sleeve gastrectomy. OBJECTIVE: The study aimed to assess the efficacy and safety of specifically designed large covered metal stents for the management of post-laparoscopic sleeve gastrectomy leaks. METHODS: Prospectively collected databases from three Italian Endoscopy Units were reviewed. The primary outcome of the study was to evaluate the clinical success of stents placement, defined as complete resolution of clinical and laboratory signs of sepsis with radiological evidence of leak closure. Secondary outcomes were stent-related adverse events and mortality. RESULTS: Twenty-one patients (67% females, mean age 45 years) were included in the study and a total of 26 stents were placed. Technical success of stent placement was achieved in all cases (100%). Clinical success was observed in 85.5% of patients. Stent-related adverse events occurred in 9 patients (43%), with stent migration as the most frequent complication (33%). Adverse events were more frequently observed in patients who had undergone bariatric surgery prior to laparoscopic sleeve gastrectomy compared to patients without previous surgery (83% et al. 27%, p=0.018). CONCLUSION: The placement of specifically designed covered metal stents appears to be an effective and safe therapeutic approach for post-laparoscopic sleeve gastrectomy leaks. Stent migration can be a frequent complication.

BACKGROUND AND STUDY AIMS: The study examines the outcomes of the 'inject and cut' endoscopic mucosal resection (EMR), for large sessile and flat colorectal polyps. PATIENTS AND METHODS: Between January 2006 and December 2008 all patients referred to our institution for EMR of large polyps were prospectively evaluated. The accuracy of lifting sign and the rate of en bloc and piecemeal resection, complications and recurrence were analyzed. RESULTS: A total of 157 patients with 182 lesions (median size 24.7 +/- 10.2 mm) were included in the study. The most frequent location was the sigmoid colon in 30.2%. Because of non-lifting sign, 5/182 lesions were referred to surgical resection and 177 (43 flat and 134 sessile) were resected, 79 (44.6%) en bloc and 98 (55.4%) piecemeal. There were 20 procedural (11.3%) and 2 late (1.1%) bleeding, 4 post-polypectomy syndrome (2.2%) and 2 perforations (1.1%). Bleeding was related to malignancy (p = 0.01). Intramucosal cancer was observed in 5 cases (2.8%) while invasive cancer was seen in 8 (4.5%). Malignancy was related to polyp size >or=30 mm (p = 0.002). Follow-up colonoscopy was performed in 147 patients with 172 EMR for a mean of 19.8 months. Recurrence was observed in 12/172 (6.9%) polyps. CONCLUSION: Inject and cut EMR is practical and effective with a low risk of complication and local recurrence.

BACKGROUND: The most common complication of polypectomy is hemorrhage, and various techniques have been used to prevent this complication. AIM: This study evaluates the outcomes of endoclip-assisted polypectomy in patients with large pedunculated colorectal polyps, in comparison with a historical control group of patients treated with endoloop-assisted polypectomy. METHODS: Between January and December 2007, 32 patients with 32 large pedunculated polyps (>or=15 mm) were treated with endoclip-assisted polypectomy (group A). Between January and December 2006, 35 patients with 35 large pedunculated polyps were treated; 33 with endoloop-assisted polypectomy (control, group B) and two cases with endoclips and needle knife, which were included in group A for the analysis. RESULTS: The mean (+/- standard deviation [SD]) size of polyp head was 26.8 +/- 8.1 mm (range 15-50) in group A and 22.3 +/- 4.1 mm (range 15-30) in group B (P = 0.004). In group A, six polyps had a mean (+/-SD) head size of 40.8 +/- 5.8 mm (range 35-50) and were resected with clips and needle knife. In group A, bleeding occurred in two cases (5.9%), which were associated with the presence of cancer at histology (P = 0.006) and were managed by applying new clips. No bleeding occurred in patients of group B and no perforation and post-polypectomy syndrome occurred in either group. There were three (8.8%) cancerized adenomas in group A and one (3%) in group B. Clip application was possible in all patients, while in two cases, loop placement was impossible. CONCLUSIONS: In our experience, endoclip-assisted resection is a safe alternative to endoloop for the resection of large pedunculated colorectal polyps when endoloop placement is difficult or impossible.

BACKGROUND AND AIMS: Liver cirrhosis (LC) of any origin has always been a source of several emergencies for physicians working at the Emergency Department (ER). LC patients can present with several complications that are sometimes difficult to recognize and treat. Thus, we reviewed the literature evidence for the diagnosis and management of several LC related emergencies. METHODS: We conducted a search on the main medical databases for papers, reviews, metanalyses, case series, and RCTs using the following keywords and their associations: liver cirrhosis, variceal hemorrhage, ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, hepato-renal syndrome, emergency. RESULTS: Main LC emergencies are upper gastrointestinal hemorrhage, decompensated ascites and spontaneous bacterial peritonitis, hepatic encephalopathy, hepato-renal syndrome. Their management is partly medical and interventional. Very often, the final cure of some complications, such as hepato-renal syndrome, is represented by liver transplantation. CONCLUSION: Although LC prevalence is going to fall in the following years, due to HBV and HCV optimized treatments, its complications represent a significant admission percentage at the ER and challenge for physicians' skills.
