Background: The ileocecal valve (ICV) is considered to be one of the most difficult locations for endoscopic submucosal dissection (ESD). The objective of this study was to evaluate the efficacy and safety of traction-assisted ESD in this situation.

Methods: All patients who underwent traction-assisted ESD for an ICV lesion at three centers were identified from a prospective ESD database.

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.

What distinguishes endoscopic submucosal dissection (ESD) from endoscopic mucosal resection is the need for three foot pedals to activate the electrosurgical unit, flushing and knife injection. The lack of connection between the various pedals of different shapes and brands leads to numerous pedals displacements and potential mistakes. The aim of this study was to evaluate an Innovative PEdal FIXator (IPEFIX) to reduce pedal mistakes during ESD.

Endoscopic submucosal dissection (ESD) in colorectal lesions is demanding, and a significant rate of non-curative procedures is expected. We aimed to assess the rate of residual lesion after a piecemeal ESD resection, or after an en bloc resection but with positive horizontal margins (local-risk resection-LocRR), for colorectal benign neoplasia. A retrospective multicenter analysis of consecutive colorectal ESDs was performed.

Introduction: Endoscopic submucosal dissection (ESD) is a well-established resection technique for colorectal superficial tumors, but its role in the treatment of anorectal junction (ARJ) lesions still remains to be determined. With this study, we aimed to evaluate the feasibility, safety, and efficacy of ESD for the resection of ARJ lesions, in comparison to more proximal rectal lesions.

Methods: We performed a retrospective analysis of prospectively collected data concerning all consecutive rectal ESD procedures performed in two European centers, from 2015 to 2021.

Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is an emerging and minimally invasive technique that seems promising for treatment of focal pancreatic and peripancreatic lesions. Our aim was to prospectively evaluate the feasibility, safety, and technical and clinical success of pancreatic and extra-pancreatic EUS-RFA. We prospectively collected clinical and technical data for all patients who underwent EUS-RFA at two Belgian academic centers from June 2018 to February 2022.

Article Synopsis
  • A study examined whether a positive horizontal resection margin after endoscopic submucosal dissection (ESD) is linked to local recurrence of colorectal lesions.* -
  • The research included 354 patients with various lesions and found that, for noninvasive lesions, having a positive margin resulted in a slightly higher, but not significant, recurrence rate compared to clear margins.* -
  • However, for T1 lesions, the data indicated a notable increase in recurrence rates with positive margins, emphasizing the need for careful evaluation in these cases.*

BACKGROUND : Endoscopic submucosal dissection (ESD) in colorectal lesions is technically demanding and a significant rate of noncurative procedures is expected. We aimed to assess the rate of residual lesions after a noncurative ESD for colorectal cancer (CRC) and to establish predictive scores to be applied in the clinical setting. METHODS : Retrospective multicenter analysis of consecutive colorectal ESDs.

Emerging evidence indicates that migrants from endemic regions are at risk of delayed presentation of malaria. We report three cases of malaria occurring years after arrival in Europe. All patients were originally from Sub-Saharan Africa.
