慢性腸套疉是指腸套疊持續存在超過14天。慢性腸套疊的臨床表現與一般常見的急性腸疉有所不同,因而很容易延誤診斷。我們報告一位八歲男孩,因腸內息肉引起慢性腸套疊的症狀,而至本院求診。超音波具有相當的診斷價值。但因鋇劑灌腸無法成功而接受手術治療。根據文獻報告,大孩子的慢性腸套疉常因潛伏性的病灶引起因而常常須要接受手術治療。而慢性腸套疊在臨床上的診斷要點是:陣發性腹痛,顯著的體重減輕和腹部腫塊。
Chronic intussusception is defined as intussusception lasting for 14 days or more. Because the clinical manifestation is different from that of acute intussusception, the diagnosis is usually delayed or missed. Ultrasonography is of diagnostic value. We present a 8-year-old boy who had the complaints of marked body weight loss and intermittent abdominal pain for one month. Hydrostatic reduction failed in this case. Laparotomy revealed an ileo-colic intussusception, the leading point of which was a colonic polyp. We would like to emphasize that chronic intussusception frequently appears a nonacute abdominal condition, usually intermittent abdominal pain, and sometimes marked body weight loss and an abdominal mass. Surgical intervention is usually needed in older children because a high incidence of underlying lesions in them.
