An attempt was made to correlate Billroth II gastrectomy in steatorrhea in dogs with the length of the afferent loop. With greater lengths of afferent loop, increasing steatorrhea was noted.
Qualitative and quantitative bacteriologic studies of the duodenum were carried out before and after creation of an afferent loop. Postoperatively, there was very little change in bacterial content with different lengths. Antibiotics which reduced the bacterial count of the afferent loop did not mitigate the steatorrhea.
This study indicates that postgastrectomy steatorrhea with a Billroth II anastomosis is related to the length of the afferent loop, although the precise physiologic mechanism is not clear. Possible explanations for the steatorrhea are discussed.
