Comparative Evaluation of Gastroduodenostomy and Gastrojejunostomy for Stomach Reconstruction Following Partial Gastrectomy in Dogs

Diana A.F. Matta, Samir R. Nouh, Mahmoud El-Kammar, Ahmed O. Korritum.


The present experimental study was aimed to perform partial gastrectomy through surgical excision the distal part of the stomach in dogs (approximately 1/5 stomach size), and then performing two types of reconstruction techniques: Gastroduodenostomy (Billroth I) and Gastrojejunostomy (Billroth II). The current experimental study was carried out on 10 apparently healthy mongrel dogs (7 males and 3 non-pregnant females), aging (8 months to 2 years old) and weighing (12 to 30 kg).
Two types of surgical technique were used: A. Billroth I (Gastroduodenostomy): Partial gastroectomy with gastroduodenal anastomosis (5 dogs were used) B. Billroth II (Gastrojejunostomy): Partial gastroectomy with gastrojejunal anastomosis (5 dogs were used). All dogs recovered from anesthesia with no complications during the surgery and recovery. There was no evidence of wound infection.
Dogs started to eat on Day 3 after surgery without any sign of regurgitation. No serious postoperative complications were observed. There were no signs of premature vasomotor disturbances, such as dizziness, weakness and alimentary disorders. One month after surgery radiographic findings cleared that there was neither stricture, narrowing, obstruction nor leakage at site of anastomosis in both groups.
On conclusion; Both Billroth I and Billroth II might be considered as suitable approaches for reconstructing gastro-intestinal tract following partial gastrectomy in dogs with no particular difference in clinical and para-clinical parameters in dogs. Billroth I doesn’t change the normal anatomy and function of the digestive system as performed anastomosis of the stomach stump to the duodenum, it’s conductive to the digestion of food falling from the stomach into the intestine mixing with pancreatic, duodenal and biliary secretion while in Billroth II mixing process occurs in the jejunum. The time consumed during Billroth II operation was higher than Billroth I also the risk adjusted complication rate was also higher in Billroth II group. Billroth I method should be the first choice after a distal gastrectomy as long as the anatomic and oncological environment allows us to perform it.

Key words: Reconstructive techniques; gastroduodenostomy; gastrojejunostomy; partial gastrectomy; dogs.
