Duodenal stenosis resulting from a preduodenal portal vein and an operation for scoliosis

Figure 3 Operative findings and performed procedures in our patient. A: Operative findings. The PDPV was found to induce the severe stenosis of the duodenal first portion and the stenosis ranging from the second to third portions was the result of stretching by spinal correction. No intestinal malrotation was found. The liver was confirmed to be a symmetrical liver. The head of the pancreas was found to be attached to the stenosis of the first duodenal portion. The duodenum is colored gray in this figure; B: Performed procedures. A gastrojejunostomy with Braun’s anastomosis was performed for the stenosis in the first portion. In addition, a duodenojejunostomy between the duodenal second portion and jejunum was performed for smooth passage of the duodenal contents. The duodenum is also colored gray in this figure.
