Abstract

Introduction: The objective of this study was to describe a laparoscopic abomasal cannulation (LAC) technique, and compare the extent of the surgical trauma after LAC and open abomasal cannulation (OAC) by examining postoperative visual analog scale (VAS) pain scores and serum values of interleukin-6 and tumour necrosis factor-α in sheep. Material and Methods: Twelve healthy ewes, weighing 38-43 kg, were used. Three-portal laparoscopic techniques were used for LAC procedures. OAC was performed by a right flank laparotomy. Results: Abomasal cannulation was accomplished in all sheep without major intraoperative and postoperative complications. The abomasal contents were collected easily in both groups. Comparative studies found that open procedures exhibit a more pronounced short-term increase in cytokines and significantly higher VAS pain scores than the corresponding laparoscopic procedures. Conclusion: The laparoscopic technique proved to be less traumatic than the conventional open technique.

Abstract

The objective of this study was to describe laparoscopic-assisted colopexy (LAC) technique, and compare the extent of the surgical trauma after LAC and open colopexy (OC) by examing postoperative serum values of C-reactive protein (CRP) in dogs. Twelve healthy mixed-breed dogs with body weight ranging from 15 to 25 kg were used. Two portal sites were used for LAC procedures. OC was performed by laparotomy on linea alba. Colopexy was accomplished in all dogs without major intraoperative and postoperative complications. A permanent adhesion between the colon and abdominal wall was observed. There were statistically significant differences in serum CRP levels between LAC and OC immediately after the procedure and 1 d post operation. LAC had a similar pexy effect to OC, but had fewer surgical trauma than OC in dogs.
