Usefulness of Pyloromyotomy With Transhiatal Esophagectomy in Improving Gastric Emptying
Abstract
Methods: Forty patients with esophageal cancer underwent THE. 20 patients underwent THE without pyloromyotomy (group A), while the other 20 patients (group B) underwent THE with pyloromyotomy. Using Technetium-99 m, gastric scintigraphy-using gamma camera, was done for all the patients 6 months post-surgery to measure the gastric half emptying time (T50).
Results: For the liquid phase, the mean (T50) in the patients without pyloromytomy (group A) was 74.5 ± 56.71 minutes ± SD versus 62.85 ± 59.35 minutes ± SD in the patients with pyloromytomy (group B) which is not significant (P = 0.529). For the solid phase, the mean (T50) in patients of group A was 139.40 ± 94.156 minutes ± SD versus 141.15 ± 48.423 minutes ± SD in group B (P value 0.941) which is also not significant.
Conclusion: Six months after THE, pyloromyotomy done with THE showed no significant value on affecting the mean gastric emptying time compared to those underwent THE without pyloromyotomy.
