Clinical study of 3D laparoscopic surgery for adrenal pheochromocytoma / paraganglioma / 中华泌尿外科杂志

ABSTRACT

Objective To investigate the efficacy and safety of 3D-laparoscopic surgery in adrenalpheochromocytomas /paragangliomas.Methods From December 2012 to July 2014,23 cases of adrenal pheochromocytomas/paragangliomas were treated by 3D-laparoscopic surgery.Among them,7 cases were male and 16 cases were female,whose mean age are 47 (32-68) years old.Their clinical symptoms including sustained hypertension in 11 cases,intermittent hypertension in 8 cases,sustained hypertension with intermittent progression in 2 cases and asymptom in 2 cases.All tumors were diagnosed by endocrine examination,image test and nuclear medicine.Mean diameter of tumors are 8 cm,ranged from 3-14cm.In order to adjust the blood pressure,patients took α-receptor blocker for 2-4 weeks preoperatively.Under the general anesthesia,19 patients received the 3D-laparoscopic surgery via retroperitoneal approach and 4 cases received the procedure via peritoneal approach.Results All operations were completed successfully.There were no major intraoperative complications.Mean operating time was (78 ± 21) min and mean estimated blood loss was (54.8 ± 36.3) ml.Mean hospital stay after operation was (3.8 ± 1.4) days.The pathological diagnosis included pheochromocytomas in 15 cases and paragangliomas in 8 cases.During the 3 to 18 months following up,no recurrence or metastasis was found in this study.Conclusions 3D-laparoscopic surgery has obvious advantage in spatial location and the sense of depth for adrenal pheochromocytomas /paragangliomas,which shortens the operation time and increase the safety obviously.
