Laparoscopic Surgical Staplers: Comparative Analysis of Current Technologies and Clinical Applications

Inleiding

Surgical staplers have revolutionized modern surgery, enabling faster, more consistent tissue approximation while reducing operative time and potentially improving outcomes across a wide range of procedures. The evolution of these devices from their rudimentary origins to today’s sophisticated laparoscopic platforms represents one of the most significant technological advances in surgical instrumentation. As we navigate through 2025, the landscape of laparoscopic staplers continues to evolve rapidly, with multiple competing platforms offering varied approaches to tissue compression, staple formation, and integration with advanced imaging and sensing technologies.

The journey of surgical staplers began with basic mechanical devices designed for open surgery, progressed through early laparoscopic adaptations, and has now reached an era of sophisticated powered systems with tissue-sensing capabilities, articulation, and integration with digital surgical platforms. These developments have dramatically expanded the application of staplers from basic bowel anastomoses to complex thoracic, bariatric, and oncologic procedures. Simultaneously, the evidence base supporting these technologies has matured from case series and technical reports to high-quality comparative studies and large-scale registry analyses.

This comprehensive analysis explores the current state of laparoscopic surgical staplers in 2025, with particular focus on comparative platform capabilities, tissue-specific considerations, and clinical outcomes across different surgical applications. From basic principles to next-generation systems, we delve into the evidence-based approaches that are reshaping surgical practice and expanding the benefits of advanced stapling technology to an increasingly diverse range of procedures and patient populations.
