Objective: To compare the safety and efficacy of en bloc stapling and separate ligation techniques for renal vascular control during laparoscopic nephrectomy. Patients and Methods: Clinical data were collected from 60 patients who underwent laparoscopic nephrectomies using en bloc stapling (n = 27, group 1) or the separate ligation method (n = 33, group 2). Comparative analysis was carried out between the two groups, examining operative times, blood loss, intra- and postoperative complications and hospital stay. Results: Compared with the separate ligation method, the en bloc hilar control technique was associated with a shorter total operating time (98 vs. 121 min, p = 0.029). However, both groups were similar in terms of estimated blood loss, hemoglobin drop, changes in creatinine level and postoperative hospital stay. The total complication rates in group 1 and 2 were 3.7 and 15.1%, respectively, with a statistically significant difference. There were no complications related to the use of the endo-GIA stapler and no patients required conversion to open surgery in group 1. In group 2, 2 patients required conversion to open surgery, including 1 due to renal vein bleeding secondary to inaccurate vascular control and the other due to bleeding from the vena cava during dissection. In addition, 1 patient had a superficial bowel injury that was repaired laparoscopically and another had a superficial liver tear that was managed without conversion or transfusion. Conclusion: En bloc ligation of the renal hilum is an easy and reliable technique that allows safe and fast control of the renal pedicle. (C) 2014 S. Karger AG, Basel
