Stomach is important and biggest dilatation of alimentary canal which mainly serves the purpose of digestion of food. The stomach has two extremities cardia and pylorus, it also has fundus and body. The pyloric extremity is connected with the duodenum by pyloric canal. The gastric emptying of food is controlled by pyloric sphincter. Many problem have been diagnosed in the pylorus such as gastric and duodenal ulcers, neoplaisa, chronic gastritis, drugs and chemicals resulting in pyloric stenosis. Various surgical attempts were made in the past to treat such problems, these includes pyloromyotomy, pyloroplasty, transverse and YU advancement pyloroplasty and partial or complete pylorectomy.

Keeping in view the importance of this part of stomach two surgical procedures were tried Transverse pyloroplasty and YU advancement pyloroplasty as a solution to the obstructive problems of the pylorus. Although these techniques are well established methods and have been used by the various surgeons in the past as a remedy to the stenotic problems of the pylorus but no work has been done on comparative efficacy of these two procedures concerned.

The present project was designed to study the comparative efficacy of these two techniques. Twelve healthy mongrel dogs were selected and were divided into three groups comprising four animals each.ln group A Transverse Pyloroplasty , in group B YU Advancement Pyloroplasty was performed and dogs of C group were kept as control. The efficacy of the procedures was evaluated on basis of physical examination, radiographic evaluation, and postmortem examination.

Laparotomy was performed in aseptic condition and pylorus was exteriorized in both the groups. In dogs of group A, longitudinal incision was given over the pylorus which was closed in transversed fashion. After checking any leakage at the operated site the abdomen was closed in routine manner. In group B, Y shaped incision was given at the pylorus which was converted into U. Dogs of group C were kept as control and they were not subjected to any surgical procedure.

Barium study procedure was performed in the dogs of all groups to estimate the rate of gastric emptying and post mortem was preformed to evaluate the change in diameter of the pylorus.

The results of this study clearly indicated that although both the techniques are effective in increasing the diameter and improving the gastric emptying but Y U Advancement Pyloroplasty was more useful and effective procedure.
