経鼠径的腹腔鏡が有用であった非触知停留精巣の2例

TRANSINGUINAL LAPAROSCOPY FOR NONPALPABLE TESTIS: REPORT OF TWO CASES

　非触知停留精巣の2例に対して経鼠径的に腹腔鏡検査を行った。片側停留精巣症例では患側の鼠径管を切開し，直視下にヘルニア嚢からトロッカーを挿入し腹腔鏡検査を施行した。両側例では一側の精巣を触知したため，その精巣固定術の途中でヘルニア嚢から腹腔鏡検査を施行し，対側の非触知精巣を観察した。本法は直視下にアプローチできるため安全な方法であるばかりでなく，通常の臍下縁からの腹腔鏡と比べても観察に関しては遜色ない。

Laparoscopy was performed on 2 boys with nonpalpable testis via an inguinal approach.

A 12-year-old boy was referred for evaluation of a nonpalpable right testis. Right inguinal skin incision was done. Although inguinal ring was opened, right testis could not be found. A 5 mm. trocar was inserted under direct vision intraperitoneally and 3-zero silk string suture was secured the opening. The abdomen was insufflated using carbon dioxide. Laparoscopy was performed through the processus. The right testis was found situated away from the internal inguinal ring.
