Abstract:

This article is devoted to results of beam diagnostics, namely, ultrasonic diagnostics and spiral computed tomography at patients with clinical manifestations of the local peritonitis as a complication of microperforation of a thick gut tumor.

Aim: was to define the main beam semiotic signs of microperforation of a tumor of a thick gut with allocation of characteristic symptom group.

Materials and methods: We analyzed data of beam diagnostics of 24 patients with microperforation of a tumor of a thick gut, complicated by local peritonitis. Researches were carried out on the Brilliance 64 tomograph (Philips, Holland, 2008) and ultrasonic Philips AU-22 scanners (Philips, the USA, 2007).

Results: were estimated following semiotics signs: changes of a gut in a zone of palpatory soreness, its walls were visualized in the form of non-uniform, hypoechoic swelling with indistinct contours. Round the changed gut, perifocal infiltrate was revealed, with the form of formation of an average echogenicity, decided on an indistinct external contour. Outside the changed gut, between it and perifocal infiltrate, congestions of liquid with the wrong form were visualized. Computed tomography with contrast enhancement allowed to specify prevalence of process and point extravasation of contrast agents out of limits of a wall of hollow body in a place of perforation of the affected gut. During ultrasonography in all patients, liquid congestions in the abdominal cavity were revealed, at 17 patients - with perifocal infiltrate. In 15 patients - changes of a wall of a gut in the form of hypoechoic swelling with indistinct contours.

Conclusions: computed tomography is a method of choice in detection of tumor' prevalence and an extravasation of contrast agents. Ultrasonography is more informative in diagnostics of liquid congestions and infiltrates.
