Loops of a small bowel. Shift is characterized by change of a usual arrangement of lean and ileal guts, their pushing off to the left, to the right, down or up (fig. 1). At the same time loops of a small bowel are pulled together, it is from each other difficult to separate them, they represent one conglomerate or a ball of loops, each of which separately is not differentiated. Filling with a contrast agent more often uneven, in the form of separate inclusions. The relief is reconstructed, mobility is limited, contours in most cases indistinct.

Morphological substrate — an inflammatory and tumoral infiltration and development of cicatricial fabric in abdominal organs and retroperitoneal space. It is observed at a tumor and tumorous formations of abdominal organs and retroperitoneal space, a tubercular mesadenitis, metastasises in lymph nodes. It is distinguished at roentgenoscopy and a X-ray analysis with use of a contrast agent and pharmacological drugs in various projections in vertical and horizontal position. For clarification of the reason of a symptom the intravenous urography, research in the conditions of a pneumoperitoneum, a pneumoretroperitoneum and an angiography are recommended.
