Abstract

BACKGROUND:

Laparoscopic adrenalectomy (LA) has been shown to reduce hospital stay and morbidity when compared to open adrenalectomy (OA). It is uncertain if the laparoscopic resection of large (>/=6 cm) potentially malignant adrenal tumours is appropriate due to concern over incomplete resection and local recurrence. The aim of the present study was to compare the outcomes of LA for tumours >/=6 cm with those < 6 cm.

METHODS:

Details of all patients referred with adrenal tumours between January 1999 and January 2006 had been recorded prospectively on a database. LA was performed using a lateral transabdominal approach. Contraindications to LA were local invasion requiring en bloc resection of adjacent organs or the requirement of additional open procedures.

RESULTS:

103 patients were referred for adrenal resection. Three with metastatic adrenal carcinoma and two with severe cardiorespiratory disease were deemed unsuitable for operation. One hundred and eleven adrenalectomies were performed: 101 LAs and 10 OAs. Thirty-nine LA were for tumours >/=6 cm while nine OA were for tumours >/=6 cm. There were no significant differences between the median total anaesthetic time, postoperative complications or postoperative stay for patients undergoing LA for tumours >/=6 cm versus tumours <6 cm. Of the six conversions, five were performed for adrenal tumours >/=6 cm [local invasion (n = 3), adhesions (n = 1), primary renal carcinoma (n = 1)]. All tumours in the LA group were resected with clear margins and at a median follow up of 50 months (range 38-74 months). There has been no evidence of local recurrence.

CONCLUSIONS:

In the absence of local invasion, the outcomes of laparoscopic adrenalectomy for patients with tumours >/=6 cm were comparable to those with tumours <6 cm. This has helped confirm a policy of initial laparoscopic resection for all noninvasive adrenal tumours can be applied safely.
