Objective: To summarize our preliminary clinical experiences of laparoendoscopic single-site (LESS) retroperitoneal adrenalectomy.
Methods: Since October 2009 to January 2011, the investigators have performed LESS retroperitoneal adrenalectomy for 7 patients with adrenal tumors. A waist axillary midline incision of around 2 - 3 cm was made and a single incision for inserting a homemade port. Cambridge endo flexible laparoscopic instrument and other common laparoscopic accessories were used during the surgical procedures.
Results: LESS retroperitoneal adrenalectomies were technically successful in 6 cases with no extra skin incisions, no conversion into an open procedure or standard laparoscopy. Conversion to standard laparoscopy (3 ports) was inevitable in one case. The reason for conversion was due to tumor size (6 cm). No perioperative complication occurred. The mean operative duration was 139 min (95 - 200 min), the mean volume of blood loss 96 ml (30 - 350 ml) and the mean hospital stay 5 d (3 - 8 d).
Conclusion: LESS retroperitoneal adrenalectomy is technically feasible and safe for the treatment of small adrenal tumors.
