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

Ultrasound examination for the stomach is a non-aggressive and easy technique validated versus scintigraphy. It has been used to assess gastric motility and emptying. The adoption of the [Fluid filled stomach technique] helped a lot to overcome certain difficulties which prevent good gastric imaging namely the presence of air inside the stomach which attenuates the transmission of the U.S. waves. We studied simultaneously the rate of gastric emptying in 10 healthy controls and in 10 patients with non-ulcer dyspepsia [Chronic Upper Gastrointestinal Symptoms Without Organic lesion] after ingestion of 500 cc. freshly tap water, and 500 cc of liquid mixed meal. We found with the liquid mixed meal, that patient with non-ulcer dyspepsia had a significant delay in gastric emptying
