title: The laparoscopic approach to sacrococcygeal teratomas.
abstract: BACKGROUND
  Sacrococcygeal teratomas (SCT) are classically approached posteriorly through an inverted chevron incision. In large, external, mainly solid SCT, prior interruption of the arterial supply is warranted because of impending heart failure and life-threatening hemorrhagic diathesis. Hitherto, this has required prior laparotomy. A laparotomy is also added when the tumor extends presacrally into the pelvis. The presacral region is, however, difficult to access. A laparoscopic-assisted approach seems to offer a solution for both problems.
  
  
  METHODS
  A laparoscopic-assisted approach was used in five patients with SCT. In one neonate, it was used to interrupt the arterial blood supply only; in the other four patients, it was used to dissect the internal extension of the tumor.
  
  
  RESULTS
  Laparoscopic interruption of the median sacral artery proved to be simple in the neonate with a large, external, mainly solid SCT. In three of the remaining four patients with presacral extension of the tumor, good visualization and dissection of the intrapelvic portion of the tumor was obtained. In one patient, the procedure had to be converted because of a lack of working space due to extensive intraabdominal growth of the tumor.
  
  
  CONCLUSIONS
  A laparoscopic-assisted approach seems to be ideal for SCT. It provides the opportunity to interrupt the median sacral artery before the dissection. Moreover, it enables far better access to the presacral area than the conventional surgical approach when the SCT extends presacrally into the pelvis. Such a meticulous laparoscopic dissection may improve the functional results.
