Perforation of the esophagus is a well-described complication of pneumatic dilatation in patients with achalasia. Although successful management of these patients without surgical intervention has been reported, little follow-up data exist. We report the successful nonsurgical management of esophageal perforation after pneumatic dilatation in three patients. Manometric and radionuclide esophageal emptying studies in these patients showed satisfactory results after the dilatations despite the occurrence of perforation, and the excellent symptomatic response has been maintained during a follow-up period ranging from one to four years.

Aortic dilatation is a severe pathology that increases the risk of rupture and its hemodynamics could be accurately assessed by using the 4D flow cardiovascular magnetic resonance (CMR) technique but flow assessment under complex flow patterns require validation. The aim of this work was to develop an in vitro system compatible with CMR to assess the accuracy of volume flow measurements in dilated aortas. Approach.

Background: Achalasia is characterized by failure of relaxation of the lower oesophageal sphincter (LOS) and abnormal peristalsis during swallowing. The study aimed to observe the effects of intervention in three sub-types of achalasia and compare the intervention outcomes among the three sub-types.
Methods: Forty-one patients underwent Eckardt scoring for severity of achalasia, followed by high-resolution manometry (HRM).
