Abstract:
Objective To explore the effect of achalasia with temporary metal internal stent dilation on esophageal motility.Methods Twenty nine patients with achalasia were undertaken temporary metal internal stent placement under X ray control (stents were of 20 25 mm in diameters). After stent dilation 3 7 days, the stents were removed by endoscopy. We measured the lower esophageal sphincter (LES) residual pressure and carried out 24h pH value monitor on the patients, and only LES pressure with relaxation rate for 12 healthy subjects (HS). Results LES residual pressure before stent dilation were markedly higher than that after stent dilation ( P 0.05).Conclusions Temporary metal internal stent dilation shows LES pressure and higher rate of GER for achalasia
