Transperitoneal laparoscopic adrenalectomy: experience in 100 patients.
Between July 1992 and October 1996, 100 transperitoneal laparoscopic adrenalectomies were performed on 99 patients at our hospital and affiliated hospitals. The clinical diagnoses were primary aldosteronism (41 patients), Cushing's syndrome (15), pre-Cushing's syndrome (6), pheochromocytoma (7; 8 adrenal glands), adrenal cancer (2), nonfunctioning adenoma (22), myelolipoma (3), and complicated adrenal cyst (3). Ninety-seven glands were removed laparoscopically. The mean operative time was 240 +/- 76 (SD) minutes and the mean blood loss 68 +/- 80 mL for the series. The mean blood was 77 +/- 113 mL when the three operations that were converted to open surgery are included. The mean times for the return to a normal diet and unassisted ambulation were 1.3 +/- 0.6 and 1.4 +/- 0.8 days, respectively. The mean duration of the use of analgesics was 1.5 +/- 1.3 days, including the day of surgery. In contrast, in the latest 10 open adrenalectomies done at Kyoto University Hospital, the mean operative time was 186 +/- 53 minutes and the mean blood loss 220 +/- 170 mL. The mean times for return to a normal diet and for unassisted ambulation and the mean duration of the use of analgesics were 1.9 +/- 0.3, 2.9 +/- 1.1, and 2.9 +/- 1.7 days, respectively. Thirty-six operations, excluding one converted to open surgery, performed at Kyoto University Hospital were selected to look at the learning curve for transperitoneal laparoscopic adrenalectomy and evaluated for operative time and blood loss. The mean operative time and mean blood loss in the first 10 procedures performed at Kyoto University Hospital were 256 +/- 63 minutes and 89 +/- 57 mL; however, these values were reduced to 177 +/- 39 minutes and 48 +/- 32 mL in the next 10 procedures at the same hospital. Laparoscopic adrenalectomy via the transperitoneal anterior approach can be equivalent to open adrenalectomy in efficiency with a shorter convalescence.
