Y-U advancement pyloroplasty as an alternative to transverse pyloroplasty to relieve pyloric stenosis in dogs.

Two commonly used surgical procedures i.e., transverse pyloroplasty and Y -U advancement flap pyloroplasty were compared to observe the relieve of pyloric stenosis in dogs . In this experimental design, twelve healthy mongrel dogs were used with further division of three group s, A, B and C comprising of four dogs in each group. The dogs of group A were subjected to Transverse pyloroplasty whereas Y-U advancement pyloroplasty was performed on dogs of group B. The group C was kept as control. Both surgical techniques were assessed by normal feeding pattern, vomiting, hematemesis, hemochazia, duration of external wound healing and contrast radiography. Results indicated that Y-U advancement flap pyloroplasty was superior to the transverse pyloroplasty in terms of simplicity, safety, maximal channel size with minimal operating time and better gastric emptying time.
