腹膜后副神经节瘤39例临床分析

Objective To summarize the clinicopathologic features and clinical diagnosis and treatment experience of retroperitoneal paraganglioma. Methods This study retrospectively analyzed the clinical, pathological and follow-up data of 39 patients admitted to the First Affiliated Hospital of Xi'an Jiaotong University from 1 Oct 2012 to 1 Oct 2022 for retroperitoneal paragangliomas undergoing resection. Results There were 19 males and 20 females with tumor being functional in 11 cases (28%) and non-functional in 28 cases (72%). CT angiography showed that the tumors were distributed around the abdominal aorta and inferior vena cava in most cases. All 39 patients underwent tumor rescetion.Patients in laparoscopic group had shorter operation time and postoperative hospital saty compared with open sugery [(135±66)min vs. (194±67)min, t=-2.529, P=0.016; (6.6±2.2)d vs.(9.6±4.8)d, t=-2.096, P=0.043], while there was no statistically significant difference between the two groups in terms of intraoperative blood loss [(152±151)ml vs. (361±608)ml, t=-1.169, P=0.250]. There were no major postoperative complications in the laparoscopic group, and pulmonary infection in 1 case and intestinal obstruction in 1 case in the open group. Thrity-six cases were followed up, ranging from 2 to 115 months, 1 patient in the laparoscopic group died 1 year after surgery due to recurrence and metastasis. In the open group, 1 case recurred 2 years later and was discharged after the second operation, and 1 case died of recurrence 2 years after surgery. Conclusions Surgery is indicated for retroperitoneal paraganglioma. Adequate perioperative management is the key to the success of the operation. Laparoscopic surgery is superior to open surgery in terms of operation time and postoperative recovery .
