Background: The aim of this study was to compare the outcome of laparoscopic adrenalectomy (LA) performed for benign adrenal neoplasm to the open procedure in a similar group of patients. Methods: All consecutive patients who underwent LA between June 1996 and February 1999 were evaluated. Data analysis included patient's age and gender, indication for surgery, histological diagnosis, size of specimen, comorbid conditions, length of stay and ileus, postoperative narcotic consumption, and time to return to normal activity. The results were compared retrospectively to a well-matched group of patients who underwent an open adrenalectomy (OA). Results: Twenty-eight LA were performed in 24 patients for the following disorders: adrenocortical adenoma, 16 (four Cushing's syndrome, 12 Conn's syndrome); pheochromocytoma, 10; and nonfunctioning tumor, two. These cases were compared with a well-matched group of 28 patients who underwent OA in the same department. There were two conversions to open surgery (7%) in the laparoscopic group and no deaths in either group. Of all the evaluated parameters, the following statistically significant differences between the two groups were noted: The mean operative time was longer in the LA group (188 vs 139 min, p < 0.001.); however, this became insignificant in the last 10 cases of LA, when the mean length of surgery was reduced to 130 min. The overall morbidity was lower in the LA group (16% vs 39%, p = 0.05), as was the mean time to tolerate a regular diet (2 vs 3.9 days), mean meperidine consumption (mg) (109 vs 209), mean length of stay (4 vs 7.5 days), and mean time to return to normal activity (2.2 vs 5.2 weeks), (p < 0.001 for all). Conclusion: LA for benign adrenal disorders is a safe procedure that is associated with significantly lower morbidity, shorter ileus and hospitalization, reduced postoperative pain, and a faster return to normal activity than the open procedure.
