Transition from open to laparoscopic adrenalectomy

Background: We sought to determine the learning curve for laparoscopic adrenalectomy (LA), current use of the procedure, and if indications for adrenalectomy had changed in the past decade. Methods: A retrospective chart review was performed for all adrenalectomies after 1990. Practicing community surgeons in Oregon were mailed a questionnaire. Results: Seventy-five LAs were performed at the Oregon Health and Sciences University and Portland VA Medical Center. Average operating room (OR) time was 161 min and average estimated blood loss (EBL) was 84 ml. There were four complications and two conversions. Comparing the first 20 to the last 20 patients, OR times were 154 vs 159 min (not significant), and EBL was 102 vs 47 ml (p < 0.05). There were two vs one complications (p > 0.05) and one conversion each. Most residents completed less than two procedures during training, and community surgeons performed none during training. Of 17 currently performing LA, 14 had postresidency training. Open technique was used more often for hormonal ablation and malignancy. Conclusion: Operative time and complications do not decrease with experience, but EBL does. Few, if any, residents acquire enough experience to perform LA in practice. The procedure is performed laparoscopically more often for benign disease.
