On the etiology and therapy of prolapse of the rectum in young children. Kollmann (Med. Welt, 1927, No. 44)

According to Kollmann, two groups of causes play a role in the origin of this disease: constitutional and those directly causing the prolapse. It usually occurs in neuropathic children who have increased tendon reflexes, dermographism, symptoms of Schaustek and Aschner, strong nervous excitability, habitual vomiting, pavor nocturnus, etc. Of the anatomical features, the considerable length of the mesentery colonis and s romani, and the indirect direction of the vertebral column favor prolapse. Directly causing prolapse are diarrhea, constipation, severe pressure while urinating, coughing (especially in whooping cough).
