An upper contrast study (UCS) showed a normal-caliber anastomotic site but a narrowing in the distal esophagus consistent with CES at one year of age (Figure 1a). Endoscopic biopsies were taken and 13.5 mm balloon dilatation was applied (Figure 1b). A UCS confirmed the cystic structure was an ED (Figure 1c). The histopathology revealed the excised diverticulum contained cartilaginous tissue on esophageal side (Figure 1d).

An endoscopy (EG-450PE5, Fujinon) revealed a widely patent anastomosis at the 14th cm but a circular narrowing at the 20th cm which precluded entry into the stomach (Figure 2a-b). An endoscopic assessment showed presence of a left-sided distal esophageal diverticulum which was non-existent in previous endoscopies performed with the endoscope passing though the GEJ into the stomach readily (Figure 2c-d).

There was a left preaortic diverticular 17X14 mm cystic structure located 2 cm above gastroe-sophageal junction (Figure 3).
