[The chronic afferent loop syndrome (author's transl)].

Between 1968 and 1973, 12 patients with a chronic afferent loop syndrome were treated at the University Surgical Hospital in Munich (6 from own hospital and 6 B II resected patients from external hospitals). 11 of them had to undergo reoperation (1 patient refused). X-ray and gastroscopy confirmed the diagnosis of chronic afferent loop syndrome type I in all 12 cases. The obstruction was caused by: adhesion and kinking of the loop (7 cases), too long and mobile loops (6 cases) incorrect anastomosis (3 cases), torsion and stenosis in the mesocolonic slit (2 cases), internal hernia (1 case). 8 patients showed good operative results, in 2 patients symptoms still persist; 1 patient died of sepsis postoperatively.
