Background and Aims: EUS-guided gastroenterostomy (EUS-GE) is increasingly used for malignant gastric outlet obstruction (GOO) in inoperable patients. However, the impact of EUS-GE on patient quality of life (QoL) has not been evaluated prospectively., Methods: Consecutive patients with unresectable malignant GOO who underwent EUS-GE between August 2019 and May 2021 at 4 Spanish centers were prospectively assessed using the European Organization for Research and Treatment of Cancer QoL Questionnaire Core 30 at baseline and 1 month after the procedure. Centralized follow-up by telephone calls was undertaken. The Gastric Outlet Obstruction Scoring System (GOOSS) was used to assess oral intake, defining clinical success as a GOOSS ≥2. Differences between baseline and 30-day QoL scores were assessed using a linear mixed model., Results: Sixty-four patients were enrolled, 33 (51.6%) men, with a median age of 77.3 years (interquartile range, 65.5-86.5). The most common diagnoses were pancreatic (35.9%) and gastric (31.3%) adenocarcinoma. Thirty-seven patients (57.9%) presented a 2/3 baseline Eastern Cooperative Oncology Group performance status score. Oral intake was restarted within 48 hours in 61 patients (95.3%), and the median postprocedure hospital stay was 3.5 days (interquartile range, 2-5). The 30-day clinical success rate was 83.3%. A clinically significant increase of 21.6 points (95% confidence interval, 11.5-31.7) in the global health status scale was documented, with significant improvements in nausea and vomiting, pain, constipation, and appetite loss., Conclusions: EUS-GE relieves GOO symptoms in patients with unresectable malignancy, allowing rapid oral intake and hospital discharge. It also provides a clinically relevant increase in QoL scores at 30 days from baseline.

Background and Aims: Digital single-operator cholangioscopy (d-SOC) with cholangioscopic biopsy sampling has shown promise in the evaluation of indeterminate biliary strictures. Some studies have suggested higher sensitivity for visual impression compared with biopsy sampling, although assessors were not blinded to previous investigations. We aimed to investigate the diagnostic accuracy and interobserver agreement (IOA) of d-SOC in the visual appraisal of biliary strictures when blinded to additional information., Methods: A multicenter, international cohort study was performed. Cholangioscopic videos in patients with a known final diagnosis were systematically scored. Pseudonymized videos were reviewed by 19 experts in 2 steps: blinded for patient history and investigations and unblinded., Results: Forty-four high-quality videos were reviewed of 19 benign and 25 malignant strictures. The sensitivity and specificity for the diagnosis of malignancy was 74.2% and 46.9% (blinded) and 72.7% and 62.5% (unblinded). Cholangioscopic certainty of a malignant diagnosis led to overdiagnosis (sensitivity, 90.6%; specificity, 33%), especially if no additional information was provided. The IOA for the presence of malignancy was fair for both assessments (Fleiss' κ = .245 [blinded] and κ = .321 [unblended]). For individual visual features, the IOA ranged from slight to moderate for both assessments (κ = .059-.400 vs κ = .031-.452)., Conclusions: This study showed low sensitivity and specificity for blinded and unblinded d-SOC video appraisal of indeterminate biliary strictures, with considerable interobserver variation. Although reaching a consensus on the optical features of biliary strictures remains important, optimizing visually directed biopsy sampling may be the most important role of cholangioscopy in biliary stricture assessment., (Copyright © 2021.

Background: EUS-guided cholangiopancreatography (ESCP) allows transmural access to biliopancreatic ducts when ERCP fails. Data regarding technical details, safety, and outcomes of ESCP are still unknown., Objective: To evaluate outcomes of ESCP in community and referral centers at the initial development phase of this procedure, to identify the ESCP stages with higher risk of failure, and to evaluate the influence on outcomes of factors related to the endoscopist., Design: Multicenter retrospective study., Setting: Public health system hospitals with experience in ESCP in Spain., Patients: A total of 125 patients underwent ESCP in 19 hospitals, with an experience of <20 procedures., Intervention: ESCP., Main Outcome Measurements: Technical success and complication rates in the initial phase of implantation of ESCP are described. The influence of technical characteristics and endoscopist features on outcomes was analyzed., Results: A total of 125 patients from 19 hospitals were included. Biliary ESCP was performed in 106 patients and pancreatic ESCP was performed in 19. Technical success was achieved in 84 patients (67.2%) followed by clinical success in 79 (63.2%). Complications occurred in 29 patients (23.2%). Unsuccessful manipulation of the guidewire was responsible for 68.2% of technical failures, and 58.6% of complications were related to problems with the transmural fistula., Limitations: Retrospective study., Conclusion: Outcomes of ESCP during its implantation stage reached a technical success rate of 67.2%, with a complication rate of 23.2%. Intraductal manipulation of the guidewire seems to be the most difficult stage of the procedure., (Copyright © 2012 American Society for Gastrointestinal Endoscopy. Published by Mosby, Inc.
