Pseudoachalasia in a patient after truncal vagotomy surgery successfully treated by subsequent pneumatic dilations

Figure 1 A: Barium esophagography and upper gastrointestinal series showing an intact gastroesophageal junction; B: dilated distal esophageal lumen with food retention and narrowing of gastroesophageal junction after truncal vagotomy; C: barium esophagography showing a non-dilated esophageal lumen with smooth passage of contrast medium through gastroesophageal junction after pneumodilations.

Figure 2 Confirmation of achalasia by manometric findings of esophageal aperistalsis and incomplete relaxation of the lower esophageal sphincter during wet swallowing.

Figure 3 Manomteric studies showing restoration of esophageal motility with normal peristalsis as a healthy subject after dilations.
