Case material was reviewed to determine the value of the rectosigmoid index in the diagnosis of both segmental and total-colon aganglionosis in infants less than one month old. Data indicate that a rectosigmoid index higher than 0.9 may rule out a diagnosis of rectosigmoid aganglionosis but may be a misleading indicator of longer segment or total-colon aganglionosis.
回顾病例资料以确定直肠乙状结肠指数在诊断1个月以内婴儿节段性和全结肠无神经节细胞症中的价值。数据表明，直肠乙状结肠指数高于0.9可能排除直肠乙状结肠无神经节细胞症的诊断，但对于较长节段或全结肠无神经节细胞症可能是一个误导性指标。
