Case Report


Esophageal intramural pseudodiverticulosis (EIPD) is an uncommon benign disorder leading to esophageal strictures. The etiology remains unknown; however, anti-fungal treatments or endoscopic balloon dilation can improve early esophageal strictures and these rarely require surgical treatment. We report a case of a 46-year-old male with a 6 cm-long esophageal stricture due to EIPD, which did not improve following treatment with an anti-fungal agent, eventually causing aspiration pneumonia. Therefore, we performed a thoraco-laparoscopic esophagectomy, and his symptoms were improved after surgery. This case suggests that a surgical treatment should be considered in patients with extensive, severe strictures attributable to EIPD.
