GI-Small intestine

Acute (spastic) or chonic-reoccuring abdominal complaints.  

Short-term invaginations with spontaneous release is often seen in GI-infections.

In case of no spontaneous devagination while performing ultrasound: a pathologic trigger for the invagination (lymph node in mesenterial lymphadenitis, Meckel diverticulum, small polipous tumors) should be suspected.

Ultrasound 1: Bulls-eye structure (gut in gut) in the area of the small intestines. Often an echogenic mesenterium between the two walls of the invaginate can be seen.

Dessucation is often very short.

Ultrasound 2: Here too one sees a lymph node in the dessucated mesenterium.

Surgery / Histo  

Intestinal wall lymphomas
Purpura Schönlein Hennoch
GvH-Reactions of the intestinal wall.  

Often, spontaneous devagination.
In case of invaginate persistence: unknown.  

Controversial discussion of a case, in which we monitored the invagination. The parents dismissed surgical intervention, since no clinical symptoms were seen.  

Laurell had already written about Peyer's plaques, the possible cause of the invaginates that he described.
