Clinical Application: Q3

Q3: You operated on a colicking llama 5 days ago and have to go back in because of persistent postoperative colic. The ventral midline incision of the first surgery has become infected (do you get the impression this case is not going so well? These cases keep you humble and test your mettle for sure). To avoid the contaminated midline incision site at the second surgery, you chose to do a ventral paramedian incision, ie parallel to and about 6 cm to the side of midline.
