Abstract
BACKGROUND: Type II cesarean scar pregnancy (CSP) is a rare and serious condition. The triglyceride-glucose index (TyG) may influence postoperative recovery-related factors (PRRF) as a marker of insulin resistance. This study investigates the relationship between TyG and PRRF in patients with type II CSP undergoing transvaginal surgery. METHODS: Forty-five patients treated from January 2019 to September 2023 were analyzed. Data on surgical duration, intraoperative blood loss, length of stay, hospitalization costs, and recovery were collected and assessed against TyG levels. RESULTS: A significant correlation was found between TyG and hospitalization costs (β = -677.5, p = 0.02). Higher TyG levels were associated with shorter hospital stays and lower costs, while no significant associations were observed with other factors. CONCLUSION: TyG is associated with hospitalization costs and length of stay in type II CSP patients, suggesting its potential to predict healthcare resource utilization. Further research is needed to explore its role in surgical risk assessment.
