Study of a human excluded jejunal loop (Thiry-Vella loop).

A case of a human jejunal loop excluded from the intestinal transit was studied. The loop was located in the retrosternal space as the first step of esophageal transit reconstruction, after an unsuccessful esophagocoloplasty performed in order to treat a caustic stenosis of the esophagus. The motility, secretion of electrolytes and the absorption of glucose and alanine by the loop were determined.
