Minimal invasive surgery in pediatric solid tumors.
BACKGROUND
There is only limited experience of using the minimally invasive surgery (MIS) technique in resecting pediatric solid tumors. In this paper, we report our experience of using the MIS technique in the management of pediatric solid tumors.


METHODS
A retrospective review was undertaken on all children who had undergone MIS for their solid tumors between 1995 and 2005.


RESULTS
Over a 10-year period, there were 38 patients who had undergone MIS for tumor resection. The mean age at the time of surgery was 7.5 years (range, 1 day to 15 years). There were 22 ovarian tumors, 4 sacrococcygeal tumors, 3 adrenal tumors, 3 retroperitoneal tumors, 1 kidney tumor, 1 liver mass, 1 intra-abdominal testicular tumor, and 3 intrathoracic masses. Thirty of 38 patients had undergone a successful resection using the MIS technique (78.9%). Eight patients required a conversion to the open procedure because of limited intraperitoneal space in 7 and excessive bleeding in 1. Of the 28 successfully MIS-resected intra-abdominal tumors, 18 required enlargement of the umbilical incision and 5 required an additional Pfannenstiel incision for tumor retrieval. Enlargement of the thoracic port site for specimen retrieval was required in the 2 successfully MIS-resected intrathoracic masses. The mean operation time was 171 minutes (range, 45-275). There was no postoperative complication encountered. On an average follow-up of 3.1 years, there was no recurrence observed, even in the 7 patients with malignant tumors, and all patients with successful MIS tumor excision had good cosmetic results.


CONCLUSIONS
With the advance of laparoscopic instruments and techniques, a variety of pediatric solid tumors can be resected safely by the MIS technique. This has the potential benefit of a more rapid postoperative recovery and better cosmetic results. The role of the MIS technique in resecting malignant tumors is uncertain, as the number of cases in the current series is too small to draw any conclusion.
