“…It has been reported that propulsive peristaltic contractions could be restored after dilatation in some achalasia patients. 7 We had observed previously the restoration of peristaltic contractions in two achalasia patients after dilatation (ZF Wang, MY Ke, MW Qin, unpubl. data).…”

OBJECTIVE: To explore the effect of balloon dilatation on esophageal motility in patients with achalasia. METHODS: In 48 patients diagnosed with achalasia based on clinical observations, barium radiography, endoscopy and esophageal manometry, the following parameters were evaluated before dilatation, and 4 and 12−24 weeks after dilatation: symptom score, maximal width of esophagus (MWE), lower esophageal sphincter pressure (LESP), lower esophageal sphincter relaxation rate (LESRR), and contraction amplitude of esophageal body. RESULTS: The symptom score and MWE decreased significantly after dilatation (P < 0.05). The LESP decreased (P < 0.05) and LESRR increased (P < 0.05) significantly 4 weeks and 12−24 weeks after dilatation. The percentages of patients with LESP <2.67 kPa were 45.41% before dilatation, and 82.48% and 85.87% 4 weeks and 12−24 weeks after dilatation, respectively (P < 0.05). The percentages of patients with LESRR ≥80% were 6.74% before dilatation, and 55.97% and 43.78% 4 weeks and 12−24 weeks after dilatation, respectively (P < 0.05). Peristaltic waves were not observed after dilatation in any patient. CONCLUSIONS: Balloon dilatation may significantly improve the symptoms of achalasia and reduce esophageal distention by decreasing LESP and increasing LESRR. The mechanism by which balloon dilatation increases LESRR needs to be further studied.

“…We have not followed a validated scale (although the commonly accepted scales are also scarcely validated). We have not included chest pain, because, as has been reported by others [10], some patients presented with spastic esophageal images in the esophagogram, with a persistent or even increasingly painful reaction, even though their dysphagia had ameliorated or disappeared.…”
