Abstract Background Surgical resection is the main treatment for pheochromocytoma (PHEO). Although open surgery (OS) has been shown to be safe and feasible, the safety and efficacy of laparoscopic surgery (LS) for PHEO remain controversial due to the uncertain effects of pneumoperitoneum on haemodynamics and the complexity of the tumour itself. This study was performed to compare the treatment outcomes of OS with those of LS for patients with PHEO. Methods A systematic search through November 11, 2019, was conducted. All studies comparing outcomes of LS and OS for PHEO were included according to eligibility criteria. This meta-analysis was conducted using Review Manager Software, version 5.3, and STATA software, version 12.0. The quality of the included studies was assessed using the Newcastle-Ottawa scale. Results Fourteen studies involving 626 patients were included in this meta-analysis. LS was associated with lower rates of intraoperative haemodynamic instability (IHD) [odds ratio (OR) = 0.61, 95% CI: 0.37 to 1.00, P = 0.05], less intraoperative blood loss [weighted mean difference (WMD) = − 115.27 ml, 95% confidence interval (CI): − 128.54 to − 101.99, P < 0.00001], lower blood transfusion rates [OR = 0.33, 95% CI: 0.21 to 0.52, P < 0.00001], earlier ambulation (WMD = − 1.57 d, 95% CI: − 1.97 to − 1.16, P < 0.00001) and food intake (WMD = − 0.98 d, 95% CI: − 1.36 to − 0.59, P < 0.00001), shorter drainage tube indwelling time (WMD = − 0.51 d, 95% CI: − 0.96 to − 0.07, P = 0.02) and postoperative stay (WMD = − 3.17 d, 95% CI: − 4.76 to − 1.58, P < 0.0001), and lower overall complication rates (OR = 0.56, 95% CI: 0.35 to 0.88, P = 0.01). However, no significant differences in operative time, postoperative blood pressure control, rates of severe complications, postoperative hypotension or cardiovascular disease (CVD) were found between the two groups. Conclusions LS is safe and effective for PHEO resection. Compared with OS, LS caused less IHD, providing an equal chance to cure hypertension while also yielding a faster and better postoperative recovery.
