Objective To compare the postoperative extubation time and length of PACU retention between patients who had undergone retroperitoneal laparoscopic unilateral adrenal pheochromocytoma resection and other adrenal tumor resection.Methods A retrospective study of 57 hypertensive patients who had undergone retroperitoneal laparoscopic unilateral adrenal tumor resection under the general anesthesia was conducted.Nineteen patients with adrenal pheochromocytoma were assigned to group S,and other 38 patients were assigned to group D.We recorded and compared the gender ratio,ASA grade,age,weight,height,duration of operation and anesthesia,dosage of anes thetics,extubation time,and length of PACU retention between the two groups.Results There were no significant differences in gender ratio,ASA grade,age,weight,height,duration operation and anesthesia,as well as doses of propofol,midazolam,fentanyl and muscle relaxants between the two groups.As to extubation time and length of PACU retention,those of group S were both significantly longer than those of group D [30.0(25.0-42.5)min vs 20.0(15.0-20.0)min;70.0(57.5-82.5)min vs 45.0(33.5-55.0) min,P＜0.05,respectively].Conclusion Retroperitoneal laparoscopic unilateral adrenal pheochromocytoma resection might lead to postoperatively longer extubation time and length of PACU retention.It does not relate to the dosage of anesthetics used perioperatively.

Primary bone lymphoma (PBL) is a rare extranodal lymphoma that lacks specific clinical symptoms and imaging manifestations. Patients with PBL have been commonly treated with chemotherapy, radiotherapy or the combination of both. The prognosis of PBL is generally better than that of other extranodal lymphomas. This paper reviews the clinical symptoms, pathological diagnosis and treatment methods of PBL to deepen the understanding of the disease.
