Shunt Malfunction

Well, Daddy was scheduled for surgery to repair the hernia next Tues., Feb. 15 but in the past couple of days, it has become clear that his shunt is not functioning properly. His belly is retaining fluid again and he's gained 12lbs or so. Tomorrow he will go into radiology (for a CT scan, I'm assuming) to check what's going on. Assuming this is just a common shunt malfunction, they will remove some fluid, and he is scheduled for surgery to correct the problem (whatever they discover the problem is) on Monday. There is a possibility that they will go ahead and do the hernia repair on Monday as well, but otherwise it will be postponed. We should know more tomorrow afternoon. Sorry for the vagueness, but that's all I've got right now. We appreciate your prayers. We are all supposed to go to a baby shower for Wendi on Saturday, and are hoping that we can carry with the celebrations as planned.
