Impact of Preoperative VFA on Intraoperative Adverse Events in Patients Undergoing Laparoscopic Radical Gastrectomy

Preoperative visceral fat area (VFA) is associated with an increased incidence of postoperative complications in gastric cancer (GC). However, the relationship between VFA and intraoperative adverse events (iAEs) remains unclear. Therefore, this study aimed to evaluate the impact of preoperative VFA on iAEs in patients undergoing laparoscopic radical gastrectomy for GC, using data from two prospective trials. Simultaneously, a predictive model for iAEs was constructed to provide a basis for the early identification of high-risk populations and the implementation of personalized perioperative management measures.
