Pancreatoduodenectomy Following Preoperative Biliary Drainage Using Endoscopic Ultrasound-Guided Choledochoduodenostomy Versus a Transpapillary Stent: A Multicenter Comparative Cohort Study of the ACHBT-FRENCH-SFED Intergroup.

Background: It is unclear whether preoperative biliary drainage (PBD) by endoscopic retrograde cholangiopancreatography (ERCP) is equivalent to electrocautery-enhanced lumen-apposing metal stent (ECE-LAMS) before pancreatoduodenectomy (PD).

Methods: Patients who underwent PBD for distal malignant biliary obstruction (DMBO) followed by PD were retrospectively included in nine expert centers between 2015 and 2022. ERCP or endoscopic ultrasound-guided choledochoduodenostomy with ECE-LAMS were performed.

Oral anticoagulants but not antiplatelet agents increase the risk of delayed bleeding after endoscopic papillectomy: a large study in a tertiary referral center.

Background: Endoscopic papillectomy (EP) is an effective curative treatment in patients with ampullary adenomas. However, EP is burdened by a not-negligible risk of bleeding. The aim of this study was to determine risk factors for delayed bleeding after EP.

Pancreaticoduodenectomy following endoscopic ultrasound-guided choledochoduodenostomy with electrocautery-enhanced lumen-apposing stents an ACHBT - SFED study.

Background: After ERCP failure or if ERCP is declined for preoperative biliary drainage before pancreaticoduodenectomy, endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) with electrocautery-enhanced lumen-apposing stents (ECE-LAMS) might be needed. The aim of the present study was to assess the technical feasibility and short-term outcomes of pancreaticoduodenectomy (PD) following endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) with electrocautery-enhanced lumen-apposing stents (ECE-LAMS).

Methods: A retrospective study of all EUS-CDS procedures with ECE-LAMS followed by PD performed in France since the availability of the device in 2016.

Genomic profile concordance between pancreatic cyst fluid and neoplastic tissue.

Background: DNA mutational analysis of pancreatic cystic fluid (CF) is a useful adjunct to the evaluation of pancreatic cysts. KRAS/GNAS or RAF/PTPRD/CTNNB1/RNF43 mutations are highly specific to precancerous or advanced neoplasia. Several studies recently demonstrated the ability of next-generation sequencing (NGS) analysis to detect DNA mutations in pancreatic CF, but few studies have performed a systematic comparative analysis between pancreatic CF and neoplastic surgical tissue (NT).

Impact of needle-based confocal laser endomicroscopy on the therapeutic management of single pancreatic cystic lesions.

Background And Aim: The diagnosis and therapeutic management of large single pancreatic cystic lesions (PCLs) represent major issues for clinicians and essentially rely on endoscopic ultrasound fine-needle aspiration (EUS-FNA) findings. Needle-based confocal laser endomicroscopy (nCLE) has high diagnostic performance for PCLs. This study aimed to evaluate the impact of nCLE on the therapeutic management of patients with single PCLs.

Can endoscopic papillectomy be curative for early ampullary adenocarcinoma of the ampulla of Vater?

Background: The therapeutic role of endoscopic papillectomy (EP) for early ampullary cancer (AC) is still controversial. The aim of the present study was to evaluate the curative potential of EP for early AC and to identify predictors of lymph node metastases (LNMs).

Methods: We retrospectively reviewed 173 patients who were prospectively included in a database and who underwent EP between 1999 and 2013.

In vivo characterization of pancreatic cystic lesions by needle-based confocal laser endomicroscopy (nCLE): proposition of a comprehensive nCLE classification confirmed by an external retrospective evaluation.

Background And Aims: The differential diagnosis of solitary pancreatic cystic lesions is sometimes difficult. Needle-based confocal laser endomicroscopy (nCLE) performed during endoscopic ultrasound-fine-needle aspiration (EUS-FNA) enables real-time imaging of the internal structure of such cysts. Criteria have already been described for serous cystadenoma and intraductal papillary mucinous neoplasm (IPMN).

A novel approach to the diagnosis of pancreatic serous cystadenoma: needle-based confocal laser endomicroscopy.

Background And Study Aims: The differential diagnosis of solitary pancreatic cystic lesions is frequently difficult. Needle-based confocal laser endomicroscopy (nCLE) performed during endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a new technology enabling real-time imaging of the internal structure of such cysts. The aim of this pilot study was to identify and validate new diagnostic criteria on nCLE for pancreatic cystic lesions.

[Esophageal leiomyoma. Six cases of video-assisted enucleation].

Aim Of The Study: To report our experience with video-assisted enucleation of esophageal leiomyomas.

Method: Retrospective analysis of six (five men and a woman) patients who underwent video-assisted submucosal tumor enucleation (4 with thoracoscopy and 2 with laparoscopy).

Results: Only one patient had postoperative complications: a parietal hematoma at a trocar site and a fever with right pleural, resolved after pleural drainage.
