Hiatal hernia repairs are quite common along with WLS, as they are a common problem amongst the morbidly obese. Ditto with gallbladders - it is not overly unusual to see them removed along with WLS if they had been causing problems, or can be anticipated to cause problems. My surgeon routinely removes them when he does the DS (which is a sleeve along with malabsorptive intestinal rerouting) but only removes them with the VSG if he feels stones when he is in there doing the surgery.
Based upon that, I wouldn't expect the trifecta to be all that unusual, though I haven't gone through that myself.
