Roux-en-Y reconstruction without gastrectomy. A short-type SBE could not reach the blind end. (a) A short-type SBE could not reach the blind end because the length of the enteroscope was too short to adequately shorten the intestine. The white line indicates the course of the intestine up to the choledochojejunal anastomosis as confirmed during insufflation on radiography. (b) After switching to a long-type SBE, the intestine was successfully shortened. The blind end was reached.
