The Role of Surgical Staplers in Gastrectomy: Applications, Advancements, and Future Prospects

The application of surgical staplers in gastrectomy has become an indispensable step in modern surgical practice, mainly utilized to treat conditions like gastric cancer, peptic ulcers, and obesity. Given the stomach’s rich blood supply and delicate tissue, precise suturing and secure closure during surgery are critical. Surgical staplers provide accurate anastomosis and rapid operation, significantly reducing surgery time and minimizing both intraoperative and postoperative complications. This article discusses the advantages, technical advancements, and future prospects of surgical staplers in gastrectomy.

The principle of surgical staplers lies in efficient and precise tissue suturing and closure. In gastrectomy, it is essential to perform accurate anastomosis of the digestive tract, a task that traditionally relied on meticulous manual suturing, requiring high levels of surgical skill and experience. Manual suturing is time-consuming and often carries a higher risk of postoperative complications. Staplers, with their pin-like or ring-like devices, allow for secure and rapid tissue alignment, improving anastomotic stability and reducing complications like bleeding and leakage. Standardized and simplified stapler operations also enhance team coordination, reducing surgical complexity.

In gastrectomy, staplers are applied in several steps, each with unique characteristics across different types of procedures, such as total, distal, and proximal gastrectomy. In total gastrectomy, the stapler connects the esophagus to the small intestine to replace the removed stomach and restore the digestive pathway. In distal gastrectomy, it connects the remnant stomach to the small intestine, facilitating digestion, while in proximal gastrectomy, it secures the remnant stomach to the small intestine to reconstruct the digestive channel.

Surgical staplers bring distinct benefits to gastrectomy, particularly in terms of shortening surgery time. Gastrectomy is a complex and time-intensive procedure, especially total gastrectomy, where precision is required for each junction. Manual suturing can take hours, while staplers significantly reduce this time. The shorter surgery time lowers anesthesia risk and reduces intraoperative bleeding, improving surgical safety. Staplers also provide consistent and stable suturing results. Manual suturing quality depends on the surgeon's experience and skill, and even the most skilled surgeons may be affected by fatigue, while staplers ensure consistent stapling force and depth, maintaining high-quality results. Additionally, stapler use reduces postoperative complication rates. Common post-gastrectomy complications like anastomotic leakage and infection, which often complicate recovery, are minimized by staplers, as they allow for smoother closures with less tissue trauma, preserving local blood flow and lowering complication risks.

The main types of staplers used in gastrectomy are linear and circular staplers. Linear staplers are suited for stomach removal and small intestine anastomosis, providing a stable, straightforward, linear closure. Circular staplers are used for end-to-end anastomoses, such as those between the esophagus and small intestine or stomach and small intestine, ideal for total or partial gastrectomies that require digestive tract reconstruction. Circular staplers perform anastomoses quickly, producing smooth, tight closures. Recently, automated staplers have been introduced to gastrectomy. These devices automatically adjust stapling force and staple length based on tissue thickness, further improving anastomotic quality.

The use of surgical staplers not only enhances the safety of gastrectomy but also influences the direction of surgical advancement. As medical technology evolves, so does the sophistication of staplers. For example, biodegradable staples eliminate the need for removal, reducing patient discomfort; intelligent staplers monitor suturing quality in real-time via built-in sensors. In the future, advancements in smart, portable, and biocompatible staplers will make them even more applicable across various surgical types.

However, despite their crucial role in gastrectomy, staplers still face challenges in clinical practice. First, stapler cost remains high, making access difficult in regions with limited medical resources. Secondly, stapler operation requires professional training. Although generally standardized, surgeons must be adept at handling staplers to ensure reliable results. Additionally, individual differences in stomach tissue structure can impact suturing effectiveness, particularly for obese patients or those with severe gastric ulcers, where staplers may have limited applicability.

To further enhance stapler efficacy in gastrectomy, future research and development will focus on several areas. Material innovation, particularly biodegradable and infection-resistant materials, will make staplers safer and more eco-friendly, reducing postoperative infection risks without adverse effects. Additionally, smart technology will make staplers more precise. For instance, AI can help staplers automatically adjust stapling parameters during surgery, ensuring each staple meets tissue needs. Moreover, miniaturized stapler designs will make them more portable and applicable to minimally invasive surgeries, expanding their use.

The future potential for staplers in gastrectomy is vast. With the continuous development of biomaterials, intelligent technology, and minimally invasive techniques, staplers will continue to improve. In robotic-assisted surgery, staplers can be combined with robotic technology for highly accurate operations. In complex gastrointestinal reconstruction, robots control staplers in narrow surgical views, reducing human error.

In summary, surgical staplers in gastrectomy not only significantly enhance efficiency and safety but also propel surgery toward intelligent, minimally invasive methods. Although challenges remain, such as device costs and training, technological advances will likely address these issues. The future of surgical staplers is promising, with a growing role in gastrectomy and other surgical types, providing patients with superior healthcare.
