Sacrococcygeal teratoma in infants and children.

BACKGROUND

The purpose of this study is to share our experience with extensive sacrococcygeal teratoma, paying particular attention to neurological function, intraoperative hemorrhage, rate of tumor recurrence, and the surgical procedure.

METHODS

Infants and children with sacrococcygeal teratoma were selected and generally examined in order to detect other associated anomalies. Patients with giant sacrococcygeal tumor and high output heart failure were managed by the abdominosacral route while patients with small sacrococcygeal tumor and normal cardiac function were managed by the sacral approach. All operated patients were observed and followed-up regularly for a period of 1-3 years after tumor excision.

RESULTS

This study presents 22 patients with sacrococcygeal teratoma managed over a period of 40 months; 18 patients presented in the first 2 months of life and four children aged 2-4 years. Fifteen patients were treated by sacral excision and seven patients were corrected by abdomenosacral excision and temporary colostomy. Benign teratoma presented in 17 patients, one of whom died (6%), and five patients had malignant tumor, one of whom died (20%). The fecal and urinary state was good in all patients treated by the sacral route. Patients corrected by abdominosacral excision showed varied degrees of urinary incontinence and constipation. Survival in excised malignant tumor was good following chemotherapy; three patients received chemotherapy with a 70% survival rate.

CONCLUSION

Benign sacrococcygeal teratoma has an excellent outcome after early surgery, but the incidences of malignancy increase if resection is delayed.
