Retroperitoneoscopic adrenalectomy in semilateral supine position / 中华泌尿外科杂志

ABSTRACT

Objective To discuss the semilateral supine position for retroperitoneoscopic adrenalectomy. Methods From Jan. 2006 to Dec. 2008, 36 patients (20 males and 16 females with mean age of 43 years) underwent retroperitoneoscopic adrenalectomy in 60° -70° semilateral supine position. There were adrenal cortex adenomas in 18 cases, pheochromocytoma in 6 cases, adrenal cysts in 3 cases, myelolipoma in 2 cases, gangliocytoma in 1 case, lymphangioma in 1 case, metastatic tumor in 1 case and corticohyporplasia in 4 cases. The mean diameter of the tumors was 2.6 cm( 0.5 - 7.7 cm ). The tumors were superior to the renal pole in 5 cases, anteromedial in 10 cases and superomedial in 17 cases. The three ports that were usually used in lateral position and were placed anteriorly to create retroperitoneal place the first port was placed 2 -4 cm superior to the iliac crest along the anterior axillary line, the other two were placed just below the costal margin along the midaxillary line and at the same level along the midclavicular line, and dissected along the anterior surface of kidney to its superomedial aspect, so as to avoid the hampering of the kidney in the exposing of the diseased adrenal gland. Results The procedure was completed successfully in all of the cases with the operating time of 37 - 145 min ( mean 69 min) and intraoperative blood loss of 30 - 100 ml (mean 48 ml). Six cases had rupture of peritoneum, which were sutured and the procedure was continued to completion. The postoperative hospital stay was 3 -8 d (mean 5 d ). Thirty-five patients were available for follow-up of 3 - 28 months ( mean 14 months). The case of metastatic tumor died of the primary diseases in the 12th month postoperatively. No other complication was found. Conclusion With this alternative position and ports' location, the procedure of retroperitoneoscopic adrenalectomy could be easier and safer than the conventional position.
