“…The recurrence rate of the sphincter-preserving procedure for ischiorectal anal fistula in Japan has been reported to be 1.5% to 9.2% [15,29,34]. Since the 1980s, the seton method was classified as radical treatment for deep anal fistula because of the poor results of this sphincter-preserving procedure [37,38]. According to Kurokawa et al (2002), the basic idea of the seton method is to not open the fistula tract all at once, but to take time to open it with a rubber band or with medical wire.…”

In the 1950s, the cause of anal fistulas was identified as an infection of the anal gland (cryptoglandular infection theory). Thereafter, treatment for this disorder began in the 1960s with the lay-open procedure, which involved incising the sphincter and the fistula tract. However, it was found that too much invasion into the sphincter could result in postoperative fecal incontinence. Thus, to reduce such risk, sphincterpreserving surgery was applied for superficial anal fistula in 1961 and for deep anal fistula (ischiorectal fistula) in 1965. Over the years, more effective sphincter-preserving procedures for ischiorectal fistula have been developed to improve the quality of life of the patient. In this review article, we aim to first introduce the basic surgical techniques for ischiorectal fistula. We will discuss the anatomy of the anus and the pathogenesis of ischiorectal fistula and will provide some diagnostic methods. Representative sphincterpreserving procedures that have been performed for ischiorectal fistula since 1965 will also be categorized and outlined chronologically. The discussion will look at the following techniques for ischiorectal fistula and outline the advantages and disadvantages of each procedure so that they can be used as a reference for ischiorectal fistula surgery in the future: the lay-open procedure (fistulotomy and fistulectomy), the Hanley procedure (first partial sphincter-preserving procedure), the muscle-filling procedure, the Moriya method and Ui method (modified partial sphincter-preserving procedure), the Takano method and the sphincterpreserving lateral procedure (complete sphincter-preserving procedure), the seton method (a cross between the lay-open procedure and sphincter-preserving procedure), and the overseas sphincter-preserving procedure.

Formerly in Japan, the treatment of anal diseases was performed with techniques transmitted from Asian countries such as China and Korea using herbs, necrotizing agents, ligation, seton, and other methods. Before World War II, western medicine and techniques were brought in from Germany, including Whitehead's operation. After the war, new knowledge was introduced from the United Kingdom and the United States: ligation and excision for hemorrhoids, sphincter-preserving methods such as Hanley's and Parks' for fistulas, and sliding skin graft methods such as Carmels' for anal fissure. After their introduction, those methods were revised and improved in Japan. Unfortunately, however, the results of those improvements were not introduced to other countries in medical journals or in presentations at international conferences. At this time, I am honored to give an overview of proctology in Japan for this special Japanese issue.

After the articles by Eisenhammer, Parks, Hanley, and Goligher and the classification system established by Sumikoshi, surgeons in Japan became very active in creating and modifying new sphincter-preserving surgical procedures for low intersphincteric and ischiorectal fistulas. This article reviews the literature, summarizes each procedure, identifies the transitions, and discusses recurrence rates, cures, and subsequent variations. Japanese surgeons favor sphincter-preserving techniques for low intersphincteric fistulas that involve partial or complete coring out of fistula tracts. Common sphincter-preserving procedures for ischiorectal fistulas involve coring-out techniques and muscle-filling procedures. The recurrence rates of sphincter-preserving procedures for low intersphincteric fistulas are between 5 and 6 percent, whereas the recurrence rates for the sphincter-preserving techniques used on ischiorectal fistulas are in the 7 to 10 percent range.
