Objective: To investigate the effects of intraoperative hemodynamic instability on postoperative complications of laparoscopic surgery for pheochromocytoma. Methods: It was a retrospective cohort study. According to inclusion/exclusion criteria, adult patients underwent laparoscopic surgery for pheochromocytoma from January 2005 to December 2017 in Peking University First Hospital were enrolled in this study. Eligible patients were divided into two groups by evidence of postoperative complications to find out the effects of intraoperative hemodynamic instability and its' effects on other prognostic indices. The normally distributed continuous variables were compared between two groups by Student's t test, Mann-Whitney U test were used for the comparison for non-normally distributed continuous variables and χ(2) test for categorical variables. Results: A total of 198 patients were finally enrolled in this study, including 87 males and 111 females with an average age of (47±15) years. Postoperative complications occurred in 17 patients with an incidence of 8.6%, and intraoperative hemodynamic instability occurred in 45 patients (22.7%). It was found that history of stroke[odds ratio ( OR )=13.387, 95% confidence interval ( CI ): 2.284-78.460, P =0.004], intraoperative hemodynamic instability ( OR =3.351, 95% CI: 1.119-10.039, P =0.031) and intraoperative positive fluid balance (for each additional 100 ml) ( OR =1.087, 95% CI: 1.031-1.146, P =0.002)were the independent risk factors of postoperative complications of laparoscopic surgery for pheochromocytoma. Furthermore, more postoperative complications, higher rate of admitting to ICU and longer hospital stay was found in patients with hemodynamic instability. Conclusion: Intraoperative hemodynamic instability is an independent risk factor for postoperative complications of laparoscopic surgery in patients with pheochromocytoma, and it associates with more postoperative complications and higher rate of admitting to ICU.
