Retrospective study of the efficacy and complication of thoracoabdominal incision for nephrectomy: a comparison with flank approach

Abstract

This retrospective study was performed to compare the outcome of thoracoabdominal incision versus flank incision for radical nephrectomy in the patients with large renal tumors. A questionnaire assessing postoperative pain, administration of pain medications and the return to activities and work was sent to the patients who undergoing radical nephrectomy through the 11th rib (group 1: underwent flank incision, including 96 patients) or the 9th to 10th rib (group 2: undergoing thoracoabdominal incision, including 98 patients) from 2003 to 2007 in our hospital. A case retrospective analysis assessing operation time, perioperative hemorrhage volume, size of tumor, success in the treatment of tumor thrombus in renal vein or vena cava, time length of presence of drainage tube, postoperative analgesia usage and length of stay was conducted in patients whose questionnaires were returned. A total of 56 patients (58%) in group 1 and 60 (61%) in group 2 responded to the questionnaire. Time lengths of operation and presence of abdominal drainage tube were shorter in group 2 than those in group 1. Perioperative hemorrhage volume in group 2 was obviously less than that in group 1. The mean size of tumors in group 1 was significantly smaller than that in group 2 (P< 0.0005). The success rate of treating thrombus in renal vein or vena cava in group 2 was significantly higher than that in group 1 (P<0.05). Lengths of off-bed time and stay were the same in both groups. There were no differences between groups in terms of pain severity on postoperative day 1, on day of discharge and 1 month postoperatively (P >0.05). There were no significant differences between groups in the time following surgery when pain completely disappeared, when pain medications were discontinued, and when the patient returned to daily activities and work (P >0.05). The thoracoabdominal incision provides excellent exposure and allows for early vascular control. Efficacy and complication was comparable for thoracoabdominal and flank incisions in terms of incisional pain, analgesic requirements after discharge and return to normal activities.
