Esophageal intramural pseudodiverticulosis of the residual esophagus after esophagectomy for esophageal cancer

Figure 1 Endoscopy showing an anastomotic stricture with multiple diverticula (arrow) and numerous white plaques (arrow).

Figure 2 Radiological examination revealing an anastomotic stricture (arrow) (A) and numerous fine, gastrografin-filled projections (arrow) (B).

Figure 3 Computed tomography imaging showing the thickness of the wall of the residual esophagus without any sign of metastatic lesions.

Figure 4 Endoscopic examination. A: Endoscopic examination revealed that the dilated anastomosis remained and the mucosal inflammation was partially improved; B: Three weeks after discharge, endoscopic examination revealed that the dilated anastomosis remained, while the mucosal inflammation had worsened; C: Two weeks after readmission, endoscopic examination revealed improvements in the mucosal inflammation. Only tiny orifices, corresponding to pseudodiverticulosis, remained.
