[Transperitoneal laparoscopic adrenalectomy for adrenal neoplasm: a report of 371 cases].

Background And Objective: Open adrenalectomy has been almost replaced by mini-invasive laparoscopic surgery. There are two popular mini-invasive laparoscopic adrenalectomy approaches: retroperitoneal and transperitoneal approaches. This study was to summarize our experience in transperitoneal laparoscopic adrenalectomy.

Methods: In total 371 cases undergoing transperitoneal adrenalectomy in the First Affiliated Hospital of Zhengzhou University from February 2003 to August 2008 were reviewed retrospectively. There were 127 cases of primary hyperaldosteronism adenoma, 117 cases of Cushing's adenoma, 58 cases of phaeochromo-cytoma, 37 cases of incidentoma and 32 cases of other types. The type of adrenal diseases, operating time, blood loss, complications and prognosis were summarized and the operating method was analyzed.

Results: Three hundred and sixty-five out of 371 patients (98.4%) were successfully operated, five cases (1.4%) were transferred to open surgery, and one patient gave up surgery due to extensive invasion. The operating time was 40-240 min (average, 70 min). The blood loss was 20-1000 ml (average, 80 ml). Two patients suffered from diaphragm injuries, one patient had right renal vein injury and one had colon injury. The mean time of hospital stay was five days.

Conclusion: Transperitoneal laparoscopic adrenalectomy is one of the favorable approaches for the treatment of adrenal neoplasm.
