Left displaced abomasum with perforated ulcer

Jersey cow undergoing right-flank surgery for left displaced abomasum. During manual maneuvers to return the abomasum to its natural position, recent adhesions with abundant fibrin are found between the visceral peritoneum of the abomasum and the parietal peritoneum of the abdominal cavity. Proceeding cautiously, the adhesions are manually released via blunt dissection, then attempting to bring the abomasum back to the level of the laparotomy incision. If necessary, the incision is extended ventrally. In this case, a large amount of recently formed fibrin can be seen, which allowed us to completely free the abomasal wall from the abdominal wall. If adhesions are already fibrotic and impossible to resolve via blunt dissection, it may be useful to perform a left-flank laparotomy to address them directly.
