Background
LESS (laparoendoscopic single-site) surgery has been developed as a treatment option for adrenal tumors that has less postoperative pain and greater cosmetic benefits. Some reports proposed that patient selection criteria should be stringent, and pheochromocytoma (PHE) should be taken as an advanced indication. The aim of this study is to compare LESS adrenalectomy (ADX) with conventional adrenalectomy (CL-ADX) in patients with PHE, with attention paid not only to immediate postoperative outcomes but also to the intraoperative hemodynamic changes that occur with each technique.
Methods
The records of 265 consecutive patients who underwent laparoscopic ADX at Keio University Hospital in Tokyo from January 2001 to June 2011 were entered into a database. Surgical procedures were performed or supervised by two experienced laparoscopic surgeons, who performed more than 100 cases of urologic laparoscopic surgery in 2011. Twenty consecutive patients who underwent LESS-ADX from December 2009 to October 2011 were compared with patients who underwent CL-ADX (controls, n = 30) to look at differences in hemodynamic parameters and surgical outcomes in a case–control analysis.
Results
Each group was equivalent with respect to age, sex, and BMI. The mean size of 50 PHE was 45.1 ± 4.0 mm, the mean operative time was 151.8 ± 10.6 min, and there was no significant difference between the two groups. In one case of LESS-ADX, two additional ports were added. There was no significant difference between the CL-ADX and LESS-ADX groups in terms of operation time, total fluid during the operation, estimated blood loss, first oral feeding, postoperative stay in the intensive care unit, or postoperative hospital stay.
Conclusions
We consider the safety of LESS-ADX of PHE as similar to that of CL-ADX. With appropriate pre- and intraoperative hemodynamic control and experienced hands, LESS-ADX could become one of the treatments of choice for resection of PHE.
