Laparoscopic-Assisted Abdominosacral Resection for Altman Type II Sacrococcygeal Teratoma in a Neonate

Sacrococcygeal teratoma (SCT) is the most common neonatal tumor, and complete resection including the coccyx is the standard treatment. Although a combined abdominosacral approach has been traditionally used for Altman type II-III lesions, the use of laparoscopy as an adjunct to facilitate dissection and improve cosmetic outcomes has been reported in a limited number of cases.

We report a full-term male neonate with an Altman type II SCT measuring approximately 7 cm in maximal diameter, composed of both cystic and solid components. On day 6 of life, a laparoscopic-assisted abdominosacral resection was performed. Laparoscopy allowed safe mobilization of the tumor from the cranial side within the abdominal cavity, while the sacral approach enabled complete en bloc excision with the coccyx. The specimen was diagnosed as immature teratoma, Grade I. The postoperative course was uneventful, and the cosmetic result was excellent.

Laparoscopic-assisted abdominosacral resection offers a minimally invasive and cosmetically favorable alternative for selected SCT cases, enabling safe circumferential dissection while minimizing large abdominal or sacral incisions.
