Treatment of afferent loop syndrome using fluoroscopic-guided nasointestinal tube placement: Two case reports

Figure 1 In patient 1, gastroscopy revealed that the anastomosis of the esophagus and jejunum was unobstructed, but the afferent loop was so twisted that the endoscope failed to pass.

Figure 2 Abdominal contrast-enhanced computed tomography before and after fluoroscopic-guided nasointestinal tube placement. A and B: Before the placement, images show the dilatation of the afferent loop; C: Six days after placement; D: Fourteen days after placement.

Figure 3 Fluoroscopic-guided nasointestinal tube placement. A: Before the placement, abdominal Xray shows the dilatation of the afferent loop; B: Placement of the hard guide wire and guiding catheter into the duodenum.
