Article Abstract
Background And Aims: Endoscopic suturing using a conventional suturing device has a steep learning curve. This study assesses the ease of use of a novel endoscopic suturing system compared to the conventional device using a validated simulator.
Methods: This randomized, crossover study included suturing experts and novices performing pursestring suturing on a transoral outlet reduction simulator. Subjects were randomized to use the novel or conventional device first. Simulator scores and workload using National Aeronautical and Space Administration Task Load Index were recorded.
Results: Ten subjects participated (4 experts, 6 novices). The novel device achieved higher simulator scores (179.3 ± 73.7 vs. 99.8 ± 94.1; P = 0.049) and lower workload (39.2 ± 15.9 vs. 70.5 ± 22.1; P = 0.002) than the conventional device. Novices demonstrated the greatest benefit.
Conclusion: This novel endoscopic suturing system improves ease of use and reduces workload, especially in endoscopists without prior suturing experience.

Purpose: Primary ventral hernia repair is a common elective procedure; however, mesh placement practices vary widely, and there is limited evidence to guide optimal placement. This international study examined surgeons' preferences and considerations regarding mesh placement in elective primary ventral hernia repair.
Methods: We conducted an international cross-sectional survey targeting surgeons experienced in primary ventral hernia repair.

Rationale: Ureteral stricture is a complex urological condition often requiring surgical intervention. Autologous tissue grafts, such as lingual mucosa, have emerged as a promising option for reconstruction due to their favorable biocompatibility and vascularity. However, reports on complications associated with these techniques remain limited.

Endoscopy Center and Endoscopy Research Institute, Zhongshan Hospital, Fudan University, Shanghai, China.
Background And Aims: Traditional endoscopic full-thickness resection (EFTR) involves complete removal of the lesion followed by defect closure. The separated resection and closure technique results in mucosal eversion and misalignment of the muscularis propria layers, making reliable closure difficult. Here, we developed an innovative "cut-and-seal-as-you-go" technique, "Zipper-EFTR" and evaluated the feasibility and safety of the new technique.
