Rectal Prolapse in Children

어린이 탈직장의 경화요법

Because rectal prolapse in pediatric age was known to have a self-limitting natural history in weeks to years, this disease is prone to be regarded as a minor condition to the most of surgeons. But to the children and the parents who have to be suffered each time could be a heavy distress. Even though operative or nonoperative methods can be applicable for treatment, the main problem is in surgeon's side, whose preference is based on the experiences of adult patients. The authors have experienced 16 cases of ano-rectal prolapse for 9 years since 1986. Eleven of them were true rectal prolapses. In 7 cases of true type, injection therapy has been tried. One ml of five percent phenol in glycerine was injected into the submucosal layer of the ano-rectal angle level at both lateral and posterior sides. After first trial of each cases, 5 of them were cured completely so far. Recurrences were in two cases, but one of them was temporary to be subsided afterward. Complete bowel cleansing and adequate sedations were required as preoperative preparations. Two days' oral antibiotics and two weeks' laxatives for free of defecation straining were recommended after the procedure. The safety of sclerosis was supported by the experimental histology. In pediatric rectal prolapse, sclerosis seems to be a safe and effective treatment of choice without any significant morbidity.

어린이 탈직장 11례 중 7례에서 5% 페놀을 포함한 글리세린액 직장점막하주사법을 이용한 경화요법을 시행하고 그 시술방법과 치료결과를 보고하였다. 이 방법은 간단하며, 단 1회 시술 후 6례에서 완치되어 치료율도 높았다. 시술 후 합병증이 없었다는 점과 실험적 조직소견으로 보아 본 치료법이 안전한 방법이며, 경화제에 의한 점막하층의 섬유화유발이 치료기전일 가능성의 증거도 제시되었다. 외래 혹은 입원상태에서의 국소요법 혹은 전신마취하 시술 등 상황에 따라 시술법도 자유롭게 선택할 수 있으나 시술 전 장청소과정과 시술 중 좌인지감각에 의한 주의깊은 점막하층 접근은 합병증을 피하기 위하여 반드시 지켜져야할 중요한 점으로 강조되어야 하겠다. 어린이의 탈직장에 대한 치료는 성인환자들과는 반드시 구분되어야 하며, 경화요법은 안전하고 편리하며 효과적인 우선적 치료법이라고 판단된다.
