ABSTRACT
The aim of this work is to define the endosonographic criteria of fistula in ano as a trial to avoid recurrent perianal fistula. 42 patients underwent endosonography preoperatively in an outpatient setting. Analysis of endosonographic findings revealed the presence of positive results in 38 cases for positive location of an internal opening. The following endosonographic criteria were demonstrated [1] root like budding formed by the intersphincteric tract that contracts the internal sphincter [3 cases], the appearance of root like budding with internal sphincter defect [6 cases] and subepithelial breach connecting to intersphincteric tract through an internal sphincteric defect [29 cases]. False negative results were recorded in four cases. It is concluded from these findings that endosonography is of particular importance in locating the internal opening of the perianal fistula and hence helping in the prevention of recurrence
