Notes about this article

• This article describes the approximate duration of each technique and the figure given includes examination of the patient and completion of the surgical procedure.
• Deflation of the abomasum:
  • Defined as "passive" when the inflated organ deflates without any intervention from the surgeon.
  • Defined as "active" when it is necessary for the surgeon to assist with deflation by massaging the organ.
• It has been assumed that regardless of technique, all cases will receive post-operative oral rehydration therapy Fluid therapy: overview with or without transfaunation Transfaunation.
• This article has been summarized as a table LDA techniques comparison table.
