從1978年到1993年,在國泰醫院共有17例兒童腹部畸胎瘤的病例。男女比例9:8,年齡由兩天到十三歲大不等。在症狀方面,腹部腫塊最爲多見(13/18),腹脹次之(7/18)。17例中有15例爲後腹腔腫瘤,另二例分別爲胃及未下降睪丸引起之畸胎瘤。所有病人在確立診斷後均接受腫瘤切除且術後情況良好,除了一例胃畸胎瘤的病人在術後隔天因突發的呼吸竭而死亡,餘十六例均無需進一步的治療。病理檢查均爲良性,追蹤期間亦無複發情形。超音波對腫瘤的定位及診斷是一項有用的工具。對大多數的腹部畸胎瘤而言,手術切除就可算治癒,但長期追蹤仍是必要的,因爲有少數復發的病例報告。
Seventeen cases of abdominal teratoma were studied retrospectively. These patients had been diagnosed at Cathay General Hospital from 1978 to 1993. The male to female ratio was 9:8, the range of age at diagnosis was from 2 days to 13 years. The chief complaints were palpable abdominal mass in 13 patients (76 %) and abdominal distention in 7 (41%). Fifteen teratomas were located in the retroperitonium; also, I of the 17 had gastric teratoma and another, a tumor originating from an undescendedtestes. The tumors were resected in all patients. Postoperative courses were smooth except for one patient, who died suddenly on the day following surgery. No further specific management was needed because the pathologic findings were all benign in nature. Ultrasonography is of benefit in locating, as well as diagnosing, abdominal teratoma. Surgical excision is curative for the majority of cases. Long term follow-up is necessary, in consideration of the rare chance of recurrence.
