[Intestinal recirculation in the management of experimental short bowel syndrome (author's transl)]. / Recirculación intestinal como tratamiento del síndrome de intestino corto experimental

A short bowel syndrome was produced in 33 mongrel puppies less than one month of age, by resecting 80% of the small bowel. An end-to-end anastomosis was performed in 14 dogs (Group A). Sixteen dogs were reanastomosed by performing an isoperistaltic circular intestinal loop, modified from Tanner and Mackby (Group B). Three dogs had a circular loop performed using Mackby method, but this technique was abandoned because of intraluminal stasis. Long term survival on 18 dogs was 12,5% for Group A and 57% for Group B. Weight gain on the survivors was over 25% higher in Group B. Intestinal transit time was abnormally short only in Group A. The loop procedure seems worthy of further clinical trial.
