HighlightsThis report emphasizes that physicians should be alert and consider airway obstruction and signs of dyspnea as severe and threatening symptoms in extensive cases of achalasia with megaesophagus.Early surgical treatment provides a therapeutic option to obviate the occurrence of acute respiratory distress and consecutive complications.In particular, difficulties in intubation prior to surgery must be considered. Due to potential tracheomalacia, the status of “bull frog neck” in achalasia, including severe tracheal compression caused by megaesophagus with concomitant cervical swelling, may also lead to extubation problems and deserves special care in the postoperative period.
