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.

About this study

A post hoc analysis was performed using data from two previous prospective studies ([NCT02327481] and [NCT01609309]). The patients were divided into high- and low-VFA groups. All iAEs were reviewed from the surgical videos and graded using ClassIntra. Logistic regression analyses were used for the construction of nomograms as predictive models.

Treatment and study plan

Primary outcomes

intraoperative adverse events(iAEs)

Time frame: During surgery

Intraoperative adverse events (iAEs) are important indicators for evaluating surgical quality and encompass a range of circumstances such as intraoperative bleeding, injury, and anesthesia-related events that may impact postoperative outcomes

Secondary outcomes

Postoperative complications

Time frame: 30 days after surgery

Postoperative complications were evaluated according to the Clavien-Dindo classification and categorized as surgical or medical
