RESUMEN
BACKGROUND/AIMS: Polyps greater than 30 mm are classified as "giants". Their endoscopic removal represents a technical challenge. The choice of the endoscopic removal technique is important because it provides a resection sample for precise histopathological staging. This is pivotal for diagnostic, prognostic, and management purposes. METHODS: From a retrospective analysis, we obtained a sample of 38 giant polyps. Eighteen polypectomies were performed using the epinephrine volume reduction (EVR) method, nine polypectomies utilized endo-looping or clipping methods, and 11 patients underwent surgery. RESULTS: We obtained en bloc resection with the EVR method in all cases; histology confirmed the correct indication for endoscopic resection in all cases. Moreover, no early or delayed complications were observed, and no patient required hospitalization. Using endo-looping or clipping methods, we observed advanced histology in 1/9 (11.1%) cases, while another patient (1/9, 11.1%) had delayed bleeding. Among patients who underwent surgery, 5/11 (45.5%) were deemed overtreated and three had post-surgical complications. CONCLUSIONS: We propose EVR as an alternative technique for giant polyp resection due to its safety, effectiveness, cost-efficiency, and the advantage of avoiding the need to postpone polypectomy to a later time. Further prospective studies might help improve this experience and enhance the technique.
RESUMEN
BACKGROUND: Endoscopic full-thickness resection (EFTR) is an effective and safe technique for nonlifting colorectal lesions. Technical issues or failures with the full-thickness resection device (FTRD) system are reported, but there are no detailed data. The aim of our study was to quantify and classify FTRD technical failures. METHODS: We performed a retrospective study involving 17 Italian centers with experience in advanced resection techniques and the required devices. Each center shared and classified all prospectively collected consecutive failures during colorectal EFTR using the FTRD from 2018 to 2022. The primary outcome was the technical failure rate and their classification; secondary outcomes included subsequent management, clinical success, and complications. RESULTS: Included lesions were mainly recurrent (52â%), with a mean (SD) dimension of 18.4 (7.5) mm. Among 750 EFTRs, failures occurred in 77 patients (35 women; mean [SD] age 69.4 [8.9] years). A classification was proposed: type I, snare noncutting (53â%); type II, clip misdeployment (31â%); and type III, cap misplacement (16â%). Among endoscopic treatments completed, rescue endoscopic mucosal resection was performed in 57 patients (74â%), allowing en bloc and R0 resection in 71â% and 64â%, respectively. The overall adverse event rate was 27.3â%. Pooled estimates for the rates of failure, complications, and rescue endoscopic therapy were similar for low and high volume centers (Pâ=â0.08, Pâ=â0.70, and Pâ=â0.71, respectively). CONCLUSIONS: Colorectal EFTR with the FTRD is a challenging technique with a non-negligible rate of technical failure and complications. Experience in rescue resection techniques and multidisciplinary management are mandatory in this setting.
RESUMEN
BACKGROUND: Although endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) using lumen-apposing metal stents (LAMS) has become one of the treatments of choice for acute cholecystitis (AC) in fragile patients, scant data are available on real-life settings and long-term outcomes. METHODS: We performed a multicenter retrospective study including EUS-guided GBD using LAMS for AC in 19 Italian centers from June 2014 to July 2020. The primary outcomes were technical and clinical success, and the secondary outcomes were the rate of adverse events (AE) and long-term follow-up. RESULTS: In total, 116 patients (48.3% female) were included, with a mean age of 82.7 ± 11 years. LAMS were placed, transgastric in 44.8% of cases, transduodenal in 53.3% and transjejunal in 1.7%, in patients with altered anatomy. Technical success was achieved in 94% and clinical success in 87.1% of cases. The mean follow-up was 309 days. AEs occurred in 12/116 pts (10.3%); 8/12 were intraprocedural, while 1 was classified as early (<15 days) and 3 as delayed (>15 days). According to the ASGE lexicon, two (16.7%) were mild, three (25%) were moderate, and seven (58.3%) were severe. No fatal AEs occurred. In subgroup analysis of 40 patients with a follow-up longer than one year, no recurrence of AC was observed. CONCLUSIONS: EUS-GBD had high technical and clinical success rates, despite the non-negligible rate of AEs, thus representing an effective treatment option for fragile patients.
RESUMEN
BACKGROUND: The new dedicated stents for endoscopic ultrasound (EUS)-guided transluminal drainage of peripancreatic fluid collections (PFCs) demonstrated optimal efficacy and safety profiles. AIMS: This study aimed to evaluate the safety, technical and clinical success, and recurrence rate of PFCs drained with Lumen Apposing Metal Stent (LAMS) or Bi-Flanged Metal Stent (BFMS). METHODS: Data from a multicenter series of PFCs treated with LAMS or BFMS at 30 Italian centers during a 5-year period were retrieved. The rate of adverse events (AEs), technical success, clinical success, PFC recurrence were evaluated. To overcome biases, a 1-to-1 match was created using propensity score analysis. RESULTS: Out of 476 patients, 386 were treated with LAMS and 90 with BFMS, with a median follow-up of 290 days (95% CI 244 to 361). Using propensity score matching, 84 patients were assigned to each group. The incidence of AEs did not differ between the two stents (13.1% versus 15.5%, p = 0.29), mainly bleeding or recurrence rate (4.7% versus 3.5%, p = 1). Technical and clinical success in the BFMS and LAMS groups were 92% versus 95% (p = 0.36) and 91% versus 94% (p = 0.64), respectively. CONCLUSION: Our study demonstrates that LAMS and BFMS have comparable safety profiles with similar technical and clinical success rates for EUS-guided PFC drainage.

BACKGROUND AND AIMS: EUS-guided gallbladder drainage (EUS-GBD) with lumen-apposing metal stents (LAMSs) has been reported as a rescue treatment with encouraging results for the relief of jaundice in patients with distal malignant biliary obstruction (DMBO) and after failure of both ERCP and EUS-guided choledochoduodenostomy. METHODS: This was a multicenter retrospective analysis of all cases of consecutive EUS-GBD with LAMSs used as a rescue treatment for patients with DMBO in 14 Italian centers from June 2015 to June 2020. Primary endpoints were technical and clinical success, whereas the secondary endpoint was the adverse event (AE) rate. RESULTS: Forty-eight patients (52.1% women) with a mean age of 74.3 ± 11.7 years were included in the study. Biliary stricture was related to pancreatic adenocarcinoma (85.4%), duodenal adenocarcinoma (2.1%), cholangiocarcinoma (4.2%), ampullary cancer (2.1%), colon cancer (4.2%), and metastatic breast cancer (2.1%). The mean diameter of the common bile duct was 13.3 ± 2.8 mm. LAMSs were placed transgastrically in 58.3% of cases and transduodenally in 41.7%. Technical success was 100%, whereas clinical success was 81.3%, with a mean total bilirubin reduction after 2 weeks of 66.5%. The mean procedure time was 26.4 minutes, and the mean hospital stay was 9.2 ± 8.2 days. AEs occurred in 5 patients (10.4%): 3 were classified as intraprocedural and 2 were classified as delayed because they occurred after >15 days. When the American Society for Gastrointestinal Endoscopy lexicon was used, 2 AEs were mild and 3 were moderate (2 buried LAMSs). The mean follow-up was 122 days. CONCLUSIONS: Our study shows that EUS-GBD with LAMSs used as a rescue treatment for patients affected by DMBO represents a valuable option in terms of technical and clinical success rates, with an acceptable AE rate. To the best of our knowledge, this is the largest study concerning the use of this procedure. (Clinical trial registration number: NCT03903523.).

INTRODUCTION: Preoperative gastric cancer (GC) staging is the most reliable prognostic factor that affects therapeutic strategies. Contrast-enhanced computed tomography (CECT) and radial endoscopic ultrasound (R-EUS) scans are the most commonly used staging tools for GC. The accuracy of linear EUS (L-EUS) in this setting is still controversial. The aim of this retrospective multicenter study was to evaluate the accuracy of L-EUS and CECT in preoperative GC staging, with regards to depth of tumor invasion (T staging) and nodal involvement (N staging). MATERIALS AND METHODS: 191 consecutive patients who underwent surgical resection for GC were retrospectively enrolled. Preoperative staging had been performed using both L-EUS and CECT, and the results were compared to postoperative staging by histopathologic analysis of surgical specimens. RESULTS: L-EUS diagnostic accuracy for depth of invasion of the GC was 100%, 60%, 74%, and 80% for T1, T2, T3, and T4, respectively. CECT accuracy for T staging was 78%, 55%, 45%, and 10% for T1, T2, T3, and T4, respectively. L-EUS diagnostic accuracy for N staging of GC was 85%, significantly higher than CECT accuracy (61%). CONCLUSIONS: Our data suggest that L-EUS has a higher accuracy than CECT in preoperative T and N staging of GC.
RESUMEN
BACKGROUND & AIMS: Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is emerging as a safe and effective treatment for pancreatic neuroendocrine tumors. We aimed to compare EUS-RFA and surgical resection for the treatment of pancreatic insulinoma (PI). METHODS: Patients with sporadic PI who underwent EUS-RFA at 23 centers or surgical resection at 8 high-volume pancreatic surgery institutions between 2014 and 2022 were retrospectively identified and outcomes compared using a propensity-matching analysis. Primary outcome was safety. Secondary outcomes were clinical efficacy, hospital stay, and recurrence rate after EUS-RFA. RESULTS: Using propensity score matching, 89 patients were allocated in each group (1:1), and were evenly distributed in terms of age, sex, Charlson comorbidity index, American Society of Anesthesiologists score, body mass index, distance between lesion and main pancreatic duct, lesion site, size, and grade. Adverse event (AE) rate was 18.0% and 61.8% after EUS-RFA and surgery, respectively (P < .001). No severe AEs were observed in the EUS-RFA group compared with 15.7% after surgery (P < .0001). Clinical efficacy was 100% after surgery and 95.5% after EUS-RFA (P = .160). However, the mean duration of follow-up time was shorter in the EUS-RFA group (median, 23 months; interquartile range, 14-31 months vs 37 months; interquartile range, 17.5-67 months in the surgical group; P < .0001). Hospital stay was significantly longer in the surgical group (11.1 ± 9.7 vs 3.0 ± 2.5 days in the EUS-RFA group; P < .0001). Fifteen lesions (16.9%) recurred after EUS-RFA and underwent a successful repeat EUS-RFA (11 patients) or surgical resection (4 patients). CONCLUSION: EUS-RFA is safer than surgery and highly effective for the treatment of PI. If confirmed in a randomized study, EUS-RFA treatment can become first-line therapy for sporadic PI.

BACKGROUND AND AIM: The diagnostic role of endoscopic ultrasound (EUS) guided fine needle aspiration (FNA) and fine needle biopsy (FNB) of pelvic masses has not been well established. We aimed to evaluate the diagnostic accuracy of EUS plus FNA/FNB in suspected local recurrence of pelvic masses. MATERIALS AND METHODS: All consecutive patients with a history of lower gastrointestinal and pelvic mass undergone EUS-FNA/FNB were included in the study. RESULTS: In total 34 patients who underwent EUS-guided FNA or FNB of a perirectal mass were enrolled. The sampled lesion was a mass in 22 patients (64.7%) and a lymph node in 10 patients (29.4%). The univariate logistic regression analysis for diagnostic accuracy showed lesion size as a significant predictor of diagnostic accuracy [odds ratio (OR), 1.61; 1.08-2.27; P = 0.02]. Diagnostic sensitivity was 100% (71.5-100%) with EUS-FNB and 75% (34.9-96.8%) with EUS-FNA ( P = 0.12); specificity was 100% in both groups ( P = 1.0). Sample adequacy was 94.1% in the whole cohort, with 20/20 adequacy rate (100%) in the EUS-FNB group and 12/14 (85.7%) in the EUS-FNA group ( P = 0.28). CONCLUSION: This is the first study demonstrating the diagnostic yield of EUS plus FNA/FNB in patients with pelvic masses comparing the two needles. Our results highlight the relevance of this technique, especially in undefined masses during oncological follow-up.

BACKGROUND : The advantage of using the macroscopic on-site evaluation (MOSE) technique during endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) performed with 22G Franseen needles has not been investigated. We aimed to compare EUS-FNB with MOSE vs. EUS-FNB performed with three needle passes. METHODS : This randomized trial involved 10 Italian referral centers. Consecutive patients referred for EUS-FNB of pancreatic or nonpancreatic solid lesions were included in the study and randomized to the two groups. MOSE was performed by gross visualization of the collected material by the endoscopists and considered adequate when a white/yellowish aggregate core longer than 10âmm was retrieved. The primary outcome was diagnostic accuracy. Secondary outcomes were specimen adequacy, number of needle passes, and safety. RESULTS : 370 patients with 234 pancreatic lesions (63.2â%) and 136 nonpancreatic lesions (36.8â%) were randomized (190 EUS-FNB with MOSE and 180 with standard EUS-FNB). No statistically significant differences were found between EUS-FNB with MOSE and conventional EUS-FNB in terms of diagnostic accuracy (90.0â% [95â%CI 84.8â%-93.9â%] vs. 87.8â% [95â%CI 82.1â%-92.2â%]; Pâ=â0.49), sample adequacy (93.1â% [95â%CI 88.6â%-96.3â%] vs. 95.5â% [95â%CI 91.4â%-98â%]; Pâ=â0.31), and rate of adverse events (2.6â% vs. 1.1â%; Pâ=â0.28). The median number of passes was significantly lower in the EUS-FNB with MOSE group (1 vs. 3; Pâ<â0.001). CONCLUSIONS : The accuracy of EUS-FNB with MOSE is noninferior to that of EUS-FNB with three needle passes. MOSE reliably assesses sample adequacy and reduces the number of needle passes required to obtain the diagnosis with a 22G Franseen needle.

BACKGROUND AND AIM: Intraparenchymal lung masses inaccessible through bronchoscopy or endobronchial ultrasound guidance pose a diagnostic challenge. Furthermore, some fragile or hypoxic patients may be poor candidates for transbronchial approaches. Endoscopic ultrasound-guided fine-needle aspiration/biopsy (EUS-FNA/FNB) offers a potential diagnostic approach to lung cancers adjacent to the esophagus. We aimed to evaluate the feasibility, accuracy, and safety of trans-esophageal EUS-FNA/FNB for tissue sampling of pulmonary nodules. METHODS: We retrospectively analyzed data from patients with pulmonary lesions who underwent EUS-FNA/FNB between March 2015 and August 2021 at eight Italian endoscopic referral centers. RESULTS: A total of 47 patients (36 male; mean age 64.47 ± 9.05 years) were included (22 EUS-FNAs and 25 EUS-FNBs). Overall diagnostic accuracy rate was 88.9% (76.3-96.2%). The sensitivity and diagnostic accuracy were superior for EUS FNB sampling versus EUS-FNA (100% vs. 78.73%); P = 0.05, and (100% vs. 78.57%); P = 0.05, respectively. Additionally, sample adequacy was superior for EUS-FNB sampling versus EUS-FNA (100% vs. 78.5%); P = 0.05. Multivariate logistic regression analysis for diagnostic accuracy showed nodule size at the cutoff of 15 mm (OR 2.29, 1.04-5.5, P = 0.05) and use of FNB needle (OR 4.33, 1.05-6.31, P = 0.05) as significant predictors of higher diagnostic accuracy. There were no procedure-related adverse events. CONCLUSION: This study highlights the efficacy and safety of EUS-FNA/FNB as a minimally invasive procedure for diagnosing and staging peri-esophageal parenchymal lung lesions. The diagnostic yield of EUS-FNB was superior to EUS-FNA.

INTRODUCTION: Common bile duct stones (CBDS) can spontaneously migrate through the duodenal papilla. In this case, ERCP could be unnecessary and a significant rate of complications could be avoided. In this study, we aim at retrospectively evaluating the rate of spontaneous stone passage in patients with an imaging diagnosis of CBDS and at analysing the factors associated to spontaneous stone migration. METHODS: We conducted a retrospective multi-centre analysis of patients undergoing ERCP for CBDS in a 12-month period. 1016 patients with CBDS were analysed. In all patients CBDS was diagnosed with adequate imaging methods performed prior to ERCP. ERCPs with failed biliary cannulation were excluded. Data regarding patients' characteristics, imaging findings and ERCP procedure were analysed. RESULTS: 1016 patients with CBDS undergoing ERCP were analysed (male sex 43.3%; mean age 69.9 ± 16.5 years). Diagnosis of CBDS was obtained by EUS in 415 patients (40.8%), MR in 343 (33.8%), CT in 220 (21.7%), and US in 38 (3.7%). No stones were found at ERCP in 179 patients (17.6%), in 14 (6.2%) when ERCP was performed within 6 h from imaging study, in 114 (18.5%) between 7 h and 7 days, in 32 (24.6%) between 8 and 29 days, and in 19 (43.2%) after 30 days. The rate of unnecessary ERCP occurred significantly more frequently in patients in whom imaging methods demonstrated either sludge or ≤ 5 mm CBDS (29.9 vs. 8.3%; p < 0.001). DISCUSSION: Spontaneous migration of small CBDS is a frequent event, and ≤ 5 mm size and a delay in ERCP > 7 days represent predictive factors for it. We suggest that CBDS ≤ 5 mm should not undergo immediate removal and this fact would allow reducing the rate of unnecessary ERCP with their related complications. Prospective studies are needed to confirm these results and demonstrate the safety of a conservative management in this setting.

Background and study aims Feasibility of EUS-guided choledochoduodenostomy (EUS-CDS) using available lumen-apposing stents (LAMS) is limited by the size of the common bile duct (CBD) (≤â12âmm, cut-off for experts; 15âmm, cut-off for non-experts). We aimed to assess the prevalence and predictive factors associated with CBD size ≥â12 and 15âmm in naïve patients with malignant distal biliary obstruction (MDBO). Patients and methods This was a prospective cohort study involving 22 centers with assessment of CBD diameter and subjective feasibility of the EUS-CDS performance in naïve jaundiced patients undergoing EUS evaluation for MDBO. Results A total of 491 patients (mean age 69â±â12 years) with mean serum bilirubin of 12.7â±â6.6âmg/dL entered the final analysis. Dilation of the CBD ≥â12 and 15âmm was detected in 78.8â% and 51.9â% of cases, respectively. Subjective feasibility of EUS-CDS was expressed by endosonographers in 91.2â% for a CBD ≥â12âmm and in 96.5â% for a CBD ≥â15âmm. On multivariate analysis, age ( P â<â0.01) and bilirubin level ( P â≤â0.001) were the only factors associated with both CBD dilationâ≥â12 andâ≥â15âmm. These variables were poorly associated with the extent of duct dilation; however, based on them a prediction model could be constructed that satisfactorily predicted CBD size ≥â12âmm in patients at least 70 years and a bilirubin level ≥â7âmg/dL. Conclusions Our study showed that at presentation in a large cohort of patients with MDBO, EUS-CDS can be potentially performed in three quarters to half of cases by expert and less experienced endosonographers, respectively. Dedicated stents or devices with different designs able to overcome the limitations of existing electrocautery-enhanced LAMS for EUS-CDS are needed.
RESUMEN
BACKGROUND: Neuroendocrine gastrointestinal tumors (NETs) are rare and have different natural behaviors. Surgery is the gold standard treatment for local disease while radiotherapy has been demonstrated to be ineffective. Poorly differentiated neuroendocrine carcinomas (NECs) represent only 5%-10% of digestive NETS. Due to aggressive growth and rapid metastatic diffusion, early diagnosis and a multidisciplinary approach are mandatory. The role of surgery and radiotherapy in this setting is still debated, and chemotherapy remains the treatment of choice. CASE SUMMARY: A 42-year-old male with an ulcerated bleeding rectal lesion was diagnosed with a NEC G3 (Ki67 index > 90%) on May 2015 and initially treated with 3 cycles of first-line chemotherapy, but showed early local progressive disease at 3 mo and underwent sphincter-sparing open anterior low rectal resection. In September 2015, the first post-surgery total-body computed tomography (CT) scan showed an early pelvic disease relapse. Therefore, systemic chemotherapy with FOLFIRI was started and the patient obtained only a partial response. This was followed by pelvic radiotherapy (50 Gy). On April 2016, a CT scan and 18F-fluorodeoxyglucose positron emission tomography imaging showed a complete response (CR) of the pelvic lesion, but pathological abdominal inter-aortocaval lymph nodes were observed. Due to disease progression of abdominal malignant nodes, the patient received radiotherapy at 45 Gy, and finally obtained a CR. As of January 2021, the patient has no symptoms of relapse and no late toxicity after chemotherapy or radiotherapy. CONCLUSION: This case demonstrates how a multimodal approach can be successful in obtaining long-term CR in metastatic sites in patients with high grade digestive NECs.
RESUMEN
BACKGROUND AND AIMS: The benefit of rapid on-site evaluation (ROSE) on the diagnostic accuracy of endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) has never been evaluated in a randomized study. This trial aimed to test the hypothesis that in solid pancreatic lesions (SPLs), diagnostic accuracy of EUS-FNB without ROSE was not inferior to that of EUS-FNB with ROSE. METHODS: A noninferiority study (noninferiority margin, 5%) was conducted at 14 centers in 8 countries. Patients with SPLs requiring tissue sampling were randomly assigned (1:1) to undergo EUS-FNB with or without ROSE using new-generation FNB needles. The touch-imprint cytology technique was used to perform ROSE. The primary endpoint was diagnostic accuracy, and secondary endpoints were safety, tissue core procurement, specimen quality, and sampling procedural time. RESULTS: Eight hundred patients were randomized over an 18-month period, and 771 were analyzed (385 with ROSE and 386 without). Comparable diagnostic accuracies were obtained in both arms (96.4% with ROSE and 97.4% without ROSE, P = .396). Noninferiority of EUS-FNB without ROSE was confirmed with an absolute risk difference of 1.0% (1-sided 90% confidence interval, -1.1% to 3.1%; noninferiority P < .001). Safety and sample quality of histologic specimens were similar in both groups. A significantly higher tissue core rate was obtained by EUS-FNB without ROSE (70.7% vs. 78.0%, P = .021), with a significantly shorter mean sampling procedural time (17.9 ± 8.8 vs 11.7 ± 6.0 minutes, P < .0001). CONCLUSIONS: EUS-FNB demonstrated high diagnostic accuracy in evaluating SPLs independently on execution of ROSE. When new-generation FNB needles are used, ROSE should not be routinely recommended.

Background and study aims Esophageal cancer (EC) is one of the most lethal malignancies worldwide. Staging of EC is performed with computed tomography (CT), positron-emission tomography (PET), and endoscopic ultrasonography (EUS). Patient management mostly depends on lymph node status. Compared to histopathology, the accuracy of EUS for T and N parameters is about 85â% and 75â%, respectively. Errors in staging may change prognosis. The aim of this study was to assess the role of EUS in T2-N0 EC considering the experience of two high-volume digestive endoscopic centers. Methods Two prospectively collected databases were queried to identify all patients with EC, staged as cT2N0 by EUS, with no distant metastases at CT/PET scan and who underwent transthoracic esophagectomy. Preoperative EUS staging (cTNM) was compared to histopathology of the surgical specimen (pTNM) to evaluate accuracy. Results Of 729 consecutive patients with EC between January 2011 and September 2018, 72 (49 men) had cT2N0 disease. CT and PET scans confirmed the absence of distant metastasis. In 43 of 72 patients (60â%), the evaluation was correct, 23 of 72 (31,7â%) were understaged, and six of 72 patients (8,3â%) were overstaged. Among the understaged patients, eight were understaged by tumor depth (35â%), seven by nodal involvement (30â%), and eight by both (35â%). All six patients who were overstaged had T1b-N0 disease. EUS accuracy was 77â% in staging for tumor depth and 82â% in staging for nodal metastases. The positive predictive value (PPV) for cT2N0 EC was 60â% (43 pT2N0â/72 cT2N). Conclusions The accuracy of EUS staging of T2N0 EC is low, with only 60â% of patients undergoing appropriate therapy based on histopathology.
RESUMEN
BACKGROUND & AIM: Although acute lower GI bleeding (LGIB) represents a significant healthcare burden, prospective real-life data on management and outcomes are scanty. Present multicentre, prospective cohort study was aimed at evaluating mortality and associated risk factors and at describing patient management. METHODS: Adult outpatients acutely admitted for or developing LGIB during hospitalization were consecutively enrolled in 15 high-volume referral centers. Demographics, comorbidities, medications, interventions and outcomes were recorded. RESULTS: Overall 1,198 patients (1060 new admissions;138 inpatients) were included. Most patients were elderly (mean-age 74±15 years), 31% had a Charlson-Comorbidity-Index ≥3, 58% were on antithrombotic therapy. In-hospital mortality (primary outcome) was 3.4% (95%CI 2.5-4.6). At logistic regression analysis, independent predictors of mortality were increasing age, comorbidity, inpatient status, hemodynamic instability at presentation, and ICU-admission. Colonoscopy had a 78.8% diagnostic yield, with significantly higher hemostasis rate when performed within 24-hours than later (21.3% vs.10.8%, pâ¯=â¯0.027). Endoscopic hemostasis was associated with neither in-hospital mortality nor rebleeding. A definite or presumptive source of bleeding was disclosed in 90.4% of investigated patients. CONCLUSION: Mortality in LGIB patients is mainly related to age and comorbidities. Although early colonoscopy has a relevant diagnostic yield and is associated with higher therapeutic intervention rate, endoscopic hemostasis is not associated with improved clinical outcomes [ClinicalTrial.gov number: NCT04364412].

BACKGROUND: During the COVID-19 outbreak in Italy, only fast-track endoscopic procedures have been performed; nevertheless, a significant drop in their number has been reported. We evaluated whether the pandemic has impacted the appropriateness and diagnostic yield of fast-track endoscopic procedures compared with those performed in 2019. METHODS: This retrospective study involved endoscopy services in Northern Italy. We compared data regarding endoscopic procedures performed in March and April 2020 with those performed during the same period in 2019. RESULTS: In 2020, there was a 53.6â% reduction in the number of fast-track endoscopic procedures compared with 2019. Patients undergoing endoscopy in 2020 were younger than in 2019.âBoth appropriate referral and diagnostic yield increased in 2020 for both upper and lower endoscopy. A higher rate of cancer was diagnosed in 2020 by upper endoscopy (3.6â% vs. 6.6â%; Pâ=â0.04). CONCLUSIONS: The high level of inappropriate endoscopy referrals registered in 2019 significantly improved during the COVID-19 outbreak of 2020, with an increase in the diagnostic yield.

INTRODUCTION: Nowadays, endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA), and fine needle biopsy (FNB) are considered the best procedures for the diagnosis of biliopancreatic lesions. These methods represent a milestone since they proved to be both safe for the patient and useful to achieve diagnostic material useful to plan the best treatment strategy. OBJECTIVE: Since in the literature, a debate between cytology and histology supporters is still ongoing and the trend is changing in favor of FNB, we would like to present our experience about the diagnostic yield of FNA and FNB. The aim of our study is to highlight FNA versus FNB diagnostic role of biliopancreatic lesions, highlight advantages, and drawbacks of these procedures, and our view on these 2 procedures and whether they should still be considered complementary or opposing techniques. METHODS: We retrospectively reviewed our hospital series of 469 EUS diagnostics procedures of biliopancreatic lesions performed in 419 patients, between 2015 and 2019. RESULTS: The overall adequacy rates of FNA and FNB were, respectively, 98.9 and 100%. Stratifying cases according to anatomic location of the mass (pancreas vs. biliary system), we detected 168 malignancies out of 349 pancreatic lesions (168/349; 48.1%), while biliary system cases positive for malignancy represented 33.8% (23/68 cases) (p value = 0.045, χ2 test). As for concomitant FNB, our series displayed a high rate of diagnostic concordance (88.8%). CONCLUSIONS: Despite numerous data published, it is still unclear which is the most feasible method to use; therefore, we compared FNA, FNB, or their combination to understand the best applicable technique. Our experience confirmed that FNA is extremely efficient in the diagnosis of biliopancreatic lesions, especially in the hands of expert endoscopists and pathologists. Considering anatomic location, EUS-FNA is more accurate for mass-forming neoplasms in the pancreatic parenchyma rather than for lesions of the biliary system. Moreover, concomitant FNB usually confirmed the cytological diagnosis, allowing a deeper immunohistochemical characterization of the neoplasia. This proves that a "pure" cytology and "pure" histology approach should be looked differently since these are complementary techniques especially if we can obtain a cellblock from FNA.

BACKGROUND: Inflammatory bowel disease (IBD) is usually diagnosed in subjects with gastrointestinal symptoms, but may also be asymptomatic and diagnosed incidentally. AIMS: to determine the prevalence of IBD in asymptomatic adults. METHODS: we identified subjects who underwent colonoscopy between 1 September 2013 and 31 August 2019 in a regional colorectal cancer screening program with endoscopic findings suggestive of IBD, and retrieved their clinical, histological and therapeutic information. RESULTS: 5116 subjects underwent colonoscopy, and 4640 persons were considered assessable. Of these, 54 (1.16%) had endoscopic findings suggestive of IBD, including 40 of Crohn's disease (CD) and 14 of ulcerative colitis (UC). A definite diagnosis of IBD was made in 19 patients, for an overall IBD prevalence of 0.41%, with 13 cases of CD (0.28%) and 6 of UC (0.13%). The mean follow-up was 26.8 months after the first colonoscopy. Therapy was started in 5 of 13 CD patients and all UC patients. CONCLUSION: Endoscopic findings suggestive of IBD are not infrequent in an asymptomatic colorectal cancer screening population. Visualization of the terminal ileum is recommended in this setting. A definite diagnosis of IBD was made in about 1 out of 3 subjects with endoscopic lesions. Most IBD patients had a mild form of disease, but some needed biologic therapy.
