[Nerve-sparing retroperitoneal lymph node dissection for stage IIA testicular embryonal carcinoma: a case report].
A 32-year-old man who had left testicular embryonal carcinoma with low volume left para-aortic lymph node swelling was treated initially with 3 courses of cisplatin-based combination chemotherapy. Pathological findings of the primary lesion revealed no yolk sac element and no elevation of serum alpha fetoprotein (alpha-FP) and beta-human chorionic gonadotropin (beta-HCG) levels even before the left orchiectomy. Therefore, the retroperitoneal lymph node dissection (RPLND) was performed despite marked shrinkage of the enlarged nodes. The L1-3 lumber splanchnic nerves from the right sympathetic truncus were detected in the intra-aortocaval region to prevent impairment of ejaculatory function and the lymph nodes in the area were removed one by one between the preserved neurofibers. On the other hand, the left para-aortic lymphatic tissue which included enlarged nodes was dissected in en bloc manner. The pre-aortic lymphatic tissue caudally to the inferior mesenteric artery was preserved not to be touched. The patient ejaculated normally 3 weeks after the RPLND. Treatment of stage IIA disease with chemotherapy first might be helpful in performing RPLND, if necessary, with keeping both ejaculatory function and radicality.
