Prediction of Myocardial Injury After Laparoscopic Pheochromocytoma/ParaGangLioma Resection

This observational study was conducted in patients undergoing elective laparoscopic pheochromocytoma/paraganglioma(PPGL) resection. It mainly answers the following two main questions: 1. What are the risk factors for myocardial injury after laparoscopic PPGL resection？ 2. How to establish the myocardial injury prediction model of laparoscopic PPGL resection? Participants were not required to perform additional research work other than the usual postoperative follow-up within 30 days after surgery. No control group was set in this study, and no additional clinical intervention was performed.
