Laparoscopic Radical Gastrectomy for Remnant Gastric Cancer

Remnant gastric cancer (RGC) is a serious long-term complication following gastrectomy, for which radical resection remains the standard treatment. With continued advancements in laparoscopic techniques, laparoscopic radical gastrectomy (LRG) has emerged as an important therapeutic option for early-stage and select advanced cases of RGC. This procedure offers reduced surgical trauma, faster postoperative recovery, and a lower incidence of complications. However, several challenges remain in its clinical application. On the one hand, postoperative anatomical changes and intra-abdominal adhesions can limit the surgical field, complicating lymphadenectomy and digestive tract reconstruction. On the other hand, no consensus has been reached regarding the optimal surgical approach, the extent of lymphadenectomy, or the anastomotic technique, resulting in variation in procedural standardization. Nonetheless, with ongoing refinement of laparoscopic techniques, this approach has been increasingly adopted across multiple centers. Its successful implementation largely depends on the surgeons' technical proficiency and clinical experience. This study aims to systematically introduce the experiences of LRG for RGC and provide supplementary information for the existing research data on these techniques.
