Abstract

|
Sinoe it had been evidenced clinically, bacteriologically and histopathologically that infection of the anal crypts had its origin in narrow, duct-like structures which opened into or through the muscular coat of the bowel, and ended blindly in the connective tissue, etiological classification of the anal fistulas could be done.
This paper deals with the etiological classification of anal fistulas, etiological percentage of patients, the ratio of males and females, age incidence, due time for operation, operative technique and postoperative measures.
The following facts relative to 91 consecutive cases of fistula-in-ano treated at the Seoul National University Hospital from April, 1960 to September, 1965 are of interest.
Tuberculosis accounted for 5.49%- Cancer was initiating factor in 4.39%, and fissre-in-ano in 5.49%. Anal cancer was developed from anal fistula in 1.09%. The remaining 83.51% were due to infection arising in the anal crypts.
The disease was more common in males, 76.92% than in females, 23.08%, and 63.73% of the patients were in the age group between 21 to 40 years of age.
Immediate incision and drainage for the abscesses about the rectum which were not only due to non-specific infection but tuberculous in origin are required to reduce the necrosis of overlying tissue.
The sphincter muscle can be cut not only posteriorly, but anteriorly or at a diagonal without the development of incontinence.
