Publisher: 2011 Dissertation note: The dog's stomach is a sac-like structure designed to store large volumes of food and begin the digestive process. Where the stomach empties into the duodenum, there is a circular valve-like muscle called the pyloric sphincter. The stomach can be divided into cardia, fundus, body, antrum, and pylorus. Gastric glands provide all the secretions.The stomach wall is made up of different layers, which are (from lumen outwards). The mucosa, the submucosa, two layers of muscularis, with an outer longitudinal and an inner circular layer the serosa.
Nonspecific, self-resolving acute gastritis or gastroenteritis is the most common GI disease seen in small animals. Congenital pyloric stenosis caused by congenital muscular hypertrophy also leads to pyloric outflow Obstruction. Acquired pyloric stenosis may be the result of external compression of the pylorus, caused, for example, by a pancreatic or hepatic tumor. Pyloric obstruction is common in humans and dogs. The only conclusive diagnostic test for pyloric stenosis is a satisfactory response to surgery, Ramstedt's pyloromyotomy being the simple and safest procedure. Various surgical procedure have been described for the relief of pyloric stenosis. Pyloroplasty (Heinekemukulicz procedure) , Y-U pyloroplasty, gasttroduodenostomy, gastrojejunostomy , and the procedures including the various bypass operations.
In the view of above the present study was designed to evaluate the efficacy of Biliroth I, Biliroth II, and Roux-en-y resection procedure as a treatment of pyloric stenosis in dogs with special emphasis on the effectiveness of procedures used in the terms of physical evaluation, healing of wound, radiography, and postmortem studies. Twenty four mongrel dogs were selected and divided into four groups comprising six animals each.
In group A, group B, and group C, Biliroth I, biliroth II, and roux-en-y resection procedures were used respectively. Group D was kept as a control group.
The operations were conducted in aseptic condition. The stomach was exposed through the celiotomy incision to proceed the three surgical procedures in dogs of group A, group B, and group C. The incision was closed in routine manner. Clinical evaluation was performed to evaluate the efficacy of the techniques and postmortem was performed to see the gross changes in the stomach and abdomen cavity of dog. The results of this study suggested that all the three procedures are effective roux-en-Y resection procedure was more effective and useful. Although Roux-en-Y resection procedure is more difficult procedure to perform but it is more effective than Biliroth - I and Billroth - II procedures regarding clinical evaluation (vomiting, diarrhea, healing of wound) delayed gastric emptying time and least postoperative complications and postmortem studies.
