Abstract
BACKGROUND: At present, the concept of surgical treatment of gastric cancer (GC) has changed from "radical treatment" to "care for patients" to a certain extent. The reconstruction method is the most likely to affect the postoperative life of the patient. Currently, the traditional Roux-en-Y esophagojejunostomy anastomosis is a commonly used method for gastrointestinal reconstruction after total gastrectomy for GC. However, more recent studies have shown that the traditional Roux-en-Y anastomosis is complicated in operation procedure, with more reconstruction steps and longer reconstruction time, and the incidence of postoperative complications such as adhesive intestinal obstruction, internal abdominal hernia and volvulus is high. Moreover, the incidence of Roux stasis syndrome is 10%-30% after traditional Roux-en-Y reconstruction. Thus, we modified the traditional Roux-en-Y alimentary tract reconstruction, and designed a new digestive tract reconstruction method for laparoscopy-assisted Roux-en-Y anastomosis for total gastrectomy of GC. AIM: To evaluate the clinical advantages, feasibility, and safety of a modified Roux-en-Y digestive tract reconstruction in laparoscopy-assisted total gastrectomy for the treatment of GC compared with the traditional Roux-en-Y method. METHODS: Ninety-seven patients who underwent laparoscopy-assisted D2 radical gastrectomy (total gastrectomy) for GC were divided into two groups: fifty-four in the conventional Roux-en-Y reconstruction group (Orr group) and forty-three in the modified Roux-en-Y reconstruction group (the modified group). Perioperative and short-term outcomes were analyzed, including complications, postoperative weight loss, hemoglobin levels, and nutritional status. RESULTS: The Orr group and the modified group showed no statistically significant differences in baseline characteristics. Compared with the Orr group, the modified group had shorter digestive tract reconstruction and operation times, less intraoperative bleeding, and shorter postoperative hospital stays compared to the Orr group. Although both groups had similar amounts of intraoperative blood loss, postoperative recovery times, and hospital expenses, the Orr group experienced longer operation times and digestive tract reconstruction times. Furthermore, the modified Roux-en-Y group demonstrated significantly fewer short-term and long-term complications, with a reduced incidence of reflux esophagitis and improved nutritional status. CONCLUSION: The modified Roux-en-Y digestive tract reconstruction method after laparoscopy-assisted total gastrectomy for GC offers safety, simplicity, and a reduction in bile reflux. This method shortens operation times and minimizes postoperative complications, aligns with modern rapid rehabilitation surgery trends and potentially improves patient prognosis and overall survival. This method warrants further clinical application and promotion.
