Malformation of the anus and rectum, frequently refered to as imperforate anus are the most common of congenital anomalies among the congenital anomalies of gastrointestinal tract, occuring about once in every 5,000births. They consist of variety of lesions ranging from mild congenital stenosis of the anus which requires simple dilation for cure to complex deformities which present some of the most vexing and discouraging problem in management. This is the report of clinical analysis and evaluation of 67 patients with congenital anorectal malformation, experienced at Severance Hospital, during past 15 years form Jan. 1963 to Dec. 1978. The results of observation were as follows: 1. Incidence of observation were as follows: 2. There were 47 males and 18 females and 2 cases of unknown sex, than male/female ratio was 2.6 : 1. 3. First and second born were more commonly observed than the others. 4. High anomalies were 37.3%, intermediate anomales were 11.9% and low anomalies were 46.3%. 5. Associated anomalies were noted in 12 out of 67 cases, which consist of congenital heart diseases, skeletal anomalies, single umbillical artery, congenital megacolon etc. 6. In general, perineal anoplasty with or without preliminary colostomy were performed in low anomalies and some cases of intermediate anomalies. And abdominoperineal pull-through operation with or without preliminary colostomy were done in high anomales. 7. Complication after surgery were main wound infection ad disruption, intestinal obstruction, fecal incontinence, urinary incontinence, vaginal perforation, and urethral injury etc. 8. Overall mortality was 19.4% and operative mortality was 9.4%. 9. Factors influencing on mortality were congenital heart diseases, sepsis, prematurity, multiple congenital anomalies, respiratory insufficiency, meningomyelocele and tracheoesophageal fistula.
