Abstract
The purpose of the work is to review current data on the possibilities of transabdominal ultrasound (ultrasound) in the diagnosis of intestinal diseases, as well as to present our own results on improving the echographic visualization of the wall of the small and large intestine.
There are the following main options for the technique of transabdominal ultrasound of the intestine: 1) without any special preparation, and the study is best done on an empty stomach, but in emergency gastroenterology, echography after eating is possible; 2) enteroclisis ; 3) contrasting of the small intestine; 4) ultrasonic irrigoscopy ; 5) Ultrasound of the intestine emptied from the contents after cleaning the colon with a solution of polyethylene glycol (PEG) taken orally (as for colonoscopy ); 6) contrasting the small and large intestine with a PEG solution taken orally.
The best visualization of the intestinal wall was noted when using a two-stage application of PEG, when half the dose of PEG was taken in the evening, ultrasound was performed in the morning, and then the second half of PEG was taken and ultrasound was performed 30–120 minutes later, depending on the area of interest. The best visualization of the small intestine wall occurs 30-60 minutes after the morning PEG intake. For the diagnosis of exophytic tumors of the colon, it is proposed to perform the above-described technique of ultrasound of the colon approximately 2 hours after the second dose of PEG. Among the methods of radiation imaging, ultrasound should be the 1st line of diagnosis in inflammatory bowel diseases.
