Through a review of 83 cases reported in literature, including our experience of two successful right laparoscopic adrenalectomies performed in a 3-year-old girl for androgen-secreting adenoma and in a 9-year-old male for pheochromocitoma, we have anaIyzed the indications, the techniques and the results of laparoscopic or retroperitoneoscopic adrenalectomy in children. Nineteen pheochromocytomas, 18 neuroblastomas, 15 adenomas, 12 ganglioneuromas, 9 hyperplasias, 2 carcinomas, 1 teratoma and 1 adrenogenital syndrome have been treated with excellent results (follow-up 1 month to 4 years) with no evidence of recurrence. The age range is from 1 month to 16 years with an equal female/male ratio. The tumor size range from 10 mm to 80 mm with approximately a mean of 40 mm. Sixty-three laparoscopies of which 54 lateral and 9 anterior have been performed versus 14 posterior retroperitoneoscopies. Regarding right adrenalectomy, 29 were laparoscopic and only 2 retroperitoneoscopic. With regards to left adrenalectomy, 23 were laparoscopic and 9 retroperitoneoscopic. Looking at bilateral lesions, these tumors were approached laparoscopically in 6 cases alternating both sides and 1 retroperitoneoscopically (this case was already operated on the other side). The operative time ranged from 25 minutes in newborn to 320 minutes in bilateral cases with an average of 120 minutes. Conversion rate is higher in retroperitoneoscopy (30%) (4 cases out of 13), than laparoscopy (6%) (4 cases out of 63). Specifically, for right retroperitoneoscopic adrenalectomy conversion rate was 100% (2 cases out 2), for left retroperitoneoscopic adrenalectomy 22.2% (2 cases out 9), for right laparoscopic adrenalectomy 6.8% (2 cases out of 29) and for left laparoscopic adrenalectomy 8.6% (2 cases out of 23). Only in 1 case were blood transfusions requested. Hospital stays ranged from 35 hours to 17 days with an average of 4 days. In conclusion the indications of endoscopic adrenalectomy in children are not different from those of traditional surgery and the well-known advantages of laparoscopic adrenal surgery should be applied to pediatric patients. It seems that there is no age and tumor size limits for a well-trained surgical team. Lateral transperitoneal approach is the most utilized with the child positioned in 90-degree flank decubitus. Laparoscopy is undoubtly preferred for right adrenalectomy (93% of cases), while for left adrenalectomy retroperitoneoscopy has been used in 39% of the cases. Considering the conversion rate and on the basis of our experience with adults, we recommend laparoscopic adrenalectomy for both right and left adrenal lesions, but we think that the pediatric surgeon should feel free to choose the approach in which he/she is more skilled. However, the best surgical result will be achieved if the pediatric and adult surgeon collaborate with their different experiences. Lastly, we suggest the use of new technological devices such as Ultracision Harmonic Scalpel which was a critical factor in our two successful right adrenalectomies. |
