Background: Management of biliopancreatic pathology in Roux-en-Y gastric bypass (RYGB) patients is challenging despite the availability of multiple approaches like single-balloon enteroscopy-assisted ERCP (SBE-ERCP), laparoscopy-assisted ERCP (LA-ERCP), and EUS-directed transgastric intervention (EDGI). We evaluated the outcomes of the interchangeable combination of endoscopic procedures to treat biliopancreatic pathology in RYGB patients., Materials and Methods: This is a monocentric retrospective study of consecutive RYGB patients with biliopancreatic pathology between June 2014 and September 2023. Primary endpoints were technical success, adverse events (AE), and parameters of endoscopic procedures according to etiology. A clinically useful management algorithm was developed., Results: A total of 102 patients with RYGB (73 women; mean age 55 ± 10 years) were included. A total of 113 SBE-ERCP (in 90 patients), 26 EDGI (in 23 patients), and 2 LA-ERCP (in 2 patients) were performed. Technical success of SBE-ERCP was lower compared to EDGI (74.4% vs 95.1%, p = 0.002). The AE rate was lower using SBE-ERCP compared to EDGI (12.4% vs 38.5%, p = 0.003). Two sub-groups based on etiology were identified as "common bile duct stone" (CBDS) and "Other." In the CBDS group, the mean number and time of procedures were lower in SBE-ERCP as the first-line technique compared to first-line EDGI (1.1 vs 2.7, p < 0.00 and 91 ± 20.7 min vs 161 ± 61.3 min, p < 0.00)., Conclusion: A combination of endoscopic procedures can achieve high technical success in managing biliopancreatic pathology in RYGB patients with an acceptable AE rate. In the case of CBDS, SBE-ERCP appeared to be a good first-line single-step option. For other indications, EDGI should be proposed as the first line., (© 2024.

Background: Endoscopic treatment of biliopancreatic pathology is challenging due to surgically altered anatomy after Whipple's pancreaticoduodenectomy. This study aimed to evaluate the feasibility and safety of single-balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography (SBE-ERCP) to treat biliopancreatic pathology in patients with Whipple's pancreaticoduodenectomy surgical variants., Methods: We retrospectively analyzed 106 SBE-ERCP procedures in 46 patients with Whipple's variants. Technical and clinical success rates and adverse events were evaluated., Results: Biliary SBE-ERCP was performed in 34 patients and pancreatic SBE-ERCP in 17, including 5 with both indications. From a total of 106 SBE-ERCP procedures, 76 were biliary indication with technical success rate of 68/76 (90%) procedures and clinical success rate of 30/34 (88%) patients. Mild adverse event rate was 8/76 (11%), without serious adverse events. From a total of 106 SBE-ERCP procedures, 30 were pancreatic indication with technical success rate of 24/30 (80%) procedures (P = 0.194 vs. biliary SBE-ERCP) and clinical success rate of 11/17 (65%) patients (P = 0.016 vs. biliary SBE-ERCP). Mild adverse event rate was 6/30 (20%) (P = 0.194 vs. biliary SBE-ERCP), without serious adverse events. After SBE-ERCP failure, endoscopic ultrasound-guided drainage, percutaneous drainage and redo surgery were alternative therapeutic options., Conclusions: Biliopancreatic pathology after Whipple's pancreaticoduodenectomy variants can be treated using SBE-ERCP without serious adverse events. Technical and clinical success rates are high for biliary indications, whereas clinical success rate of pancreatic indications is significantly lower. SBE-ERCP can be considered as first-line treatment option in this patient group with surgically altered anatomy., (Copyright © 2023 First Affiliated Hospital, Zhejiang University School of Medicine in China.

Background: This study evaluated the safety and efficacy of salvage endoscopic submucosal dissection (ESD) for Barrett's neoplasia recurrence after radiofrequency ablation (RFA)., Methods: Data from patients at 16 centers were collected for a multicenter retrospective study. Patients who underwent at least one RFA treatment for Barrett's esophagus and thereafter underwent further esophageal ESD for neoplasia recurrence were included., Results: Data from 56 patients who underwent salvage ESD between April 2014 and November 2022 were collected. Immediate complications included one muscular tear (1.8%) treated with stent (Agree classification: grade IIIa). Two transmural perforations (3.6%; treated with clips) and five muscular tears (8.9%; two treated with clips) had no clinical impact and were not considered as adverse events. Seven patients (12.5%) developed strictures (grade IIIa), which were treated with balloon dilation. Histological analysis showed 36 adenocarcinoma, 17 high grade dysplasia, and 3 low grade dysplasia. En bloc and R0 resection rates were 89.3% and 66.1%, respectively. Resections were curative in 33 patients (58.9%), and noncurative in 22 patients (39.3%), including 11 "local risk" (19.6%) and 11 "high risk" (19.6%) resections. At the end of follow-up with a median time of 14 (0-75) months after salvage ESD, and with further endoscopic treatment if necessary (RFA, argon plasma coagulation, endoscopic mucosal resection, ESD), neoplasia remission ratio was 37/53 (69.8%) and the median remission time was 13 (1-75) months., Conclusion: In expert hands, salvage ESD was a safe and effective treatment for recurrence of Barrett's neoplasia after RFA treatment., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Introduction: The study aimed to develop international consensus recommendations on the safe use of lumen-apposing metal stents (LAMSs) for on- and off-label indications., Methods: Based on the available literature, statements were formulated and grouped into the following categories: general safety measures, peripancreatic fluid collections, endoscopic ultrasound (EUS)-biliary drainage, EUS-gallbladder drainage, EUS-gastroenterostomy, and gastric access temporary for endoscopy. The evidence level of each statement was determined using the Grading of Recommendations Assessment, Development, and Evaluation methodology.International LAMS experts were invited to participate in a modified Delphi process. When no 80% consensus was reached, the statement was modified based on expert feedback. Statements were rejected if no consensus was reached after the third Delphi round., Results: Fifty-six (93.3%) of 60 formulated statements were accepted, of which 35 (58.3%) in the first round. Consensus was reached on the optimal learning path, preprocedural imaging, the need for airway protection and essential safety measures during the procedure, such as the use of Doppler, and measurement of the distance between the gastrointestinal lumen and the target structure. Specific consensus recommendations were generated for the different LAMS indications, covering, among others, careful patient selection, the preferred size of the LAMS, the need for antibiotics, the preferred anatomic location of the LAMS, the need for coaxial pigtail placement, and the appropriate management of LAMS-related adverse events., Discussion: Through a modified international Delphi process, we developed general and indication-specific experience- and evidence-based recommendations on the safe use of LAMS., (Copyright © 2023 by The American College of Gastroenterology.)

Background and Aims: Circumferential endoscopic submucosal dissection (cESD) in the esophagus has been reported to be feasible in small Eastern case series. We assessed the outcomes of cESD in the treatment of early esophageal squamous cell carcinoma (ESCC) in Western countries., Methods: We conducted an international study at 25 referral centers in Europe and Australia using prospective databases. We included all patients with ESCC treated with cESD before November 2022. Our main outcomes were curative resection according to European guidelines and adverse events., Results: A total of 171 cESDs were performed on 165 patients. En bloc and R0 resections rates were 98.2% (95% confidence interval [CI], 95.0-99.4) and 69.6% (95% CI, 62.3-76.0), respectively. Curative resection was achieved in 49.1% (95% CI, 41.7-56.6) of the lesions. The most common reason for noncurative resection was deep submucosal invasion (21.6%). The risk of stricture requiring 6 or more dilations or additional techniques (incisional therapy/stent) was high (71%), despite the use of prophylactic measures in 93% of the procedures. The rates of intraprocedural perforation, delayed bleeding, and adverse cardiorespiratory events were 4.1%, 0.6%, and 4.7%, respectively. Two patients died (1.2%) of a cESD-related adverse event. Overall and disease-free survival rates at 2 years were 91% and 79%., Conclusions: In Western referral centers, cESD for ESCC is curative in approximately half of the lesions. It can be considered a feasible treatment in selected patients. Our results suggest the need to improve patient selection and to develop more effective therapies to prevent esophageal strictures., Competing Interests: Disclosure The following authors disclosed financial relationships: E.

Background: Combined endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound-guided tissue acquisition (EUS-TA) are accurate procedures for the diagnosis and staging of mediastinal lymph nodes (MLNs) in lung cancer. However, the respective contribution of separate and combined procedures in diagnosis and staging has not been fully studied. The aim of this study was to assess their respective performances., Methods: Patients with suspected malignant MLNs in lung cancer or recurrence identified by PET-CT who underwent combined EBUS-TBNA and EUS-TA were retrospectively reviewed., Results: A total of 141 patients underwent both procedures. Correct diagnosis was obtained in 82% with EBUS-TBNA, 91% with EUS-TA, and 94% with the combined procedure. The overall sensitivity, specificity, and positive and negative predictive values (PPV and NPV) of EBUS-TBNA, EUS-TA, and the combined procedure for diagnosing malignancy were [75%, 100%, 100%, 58%], [87%, 100%, 100%, 75%], and [93%, 100%, 100%, 80%], respectively, with a significantly better sensitivity of the combined procedure ( p < 0.0001). Staging (82/141 patients) was correctly assessed in 74% with EBUS-TBNA, 68% with EUS-TA, and 85% with the combined procedure. The overall sensitivity, specificity, PPV, and NPV of EBUS-TBNA, EUS-TA, and the combined procedure for lung cancer staging were [62%, 100%, 100%, 55%], [54%, 100%, 100%, 50%], and [79%, 100%, 100%, 68%], respectively, significantly better in terms of sensitivity for the combined procedure ( p < 0.001)., Conclusion: The combined EBUS-EUS approach in lung cancer patients showed better accuracy and sensitivity in diagnosis and staging when compared with EBUS-TBNA and EUS-TA alone.
