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.
