Abstract

Objectives: To report our initial experience with transumbilical laparo-endoscopic single-site adrenalectomy for adrenal tumors by using a single port with a multichannel cannula and bent laparoscopic instrumentation. Methods: Between December 2009 and December 2010, 30 patients underwent transumbilical laparo-endoscopic single-site adrenalectomy at our hospital. The procedure was carried out for adrenal cortical adenoma in 17 patients, adrenal pheochromocytoma in seven patients and other types of tumors in six patients. A multichannel port, bent laparoscopic instruments and Opti4 laparoscopic electrodes were used in all patients. The intraperitoneal space was approached through the umbilicus. The multichannel port was placed through a 2-cm incision at the inner edge of the umbilicus. A 5-mm flexible laparoscope was introduced to maintain an adequate laparoscopic view, and surgical specimens were extracted using an Endocatch bag. Results: All procedures were successfully completed, with only one incision through the umbilicus, and without conversion to a standard laparoscopic approach. Mean operative time was 120.1±34.7min. Tumor laterality and patient body mass index did not affect surgical morbidity. The initial 15 patients had a significantly longer mean pneumoperitoneum time (95.8±37.5min) than the last 15 patients (70.5±18.7min). Only one postoperative complication was observed (postoperative hematoma). Conclusions: A transumbilical approach for laparo-endoscopic single-site adrenalectomy is safe and feasible, and it results in superior cosmesis. Improvements in surgical devices might facilitate further development of this approach.
