CTscan=Possible umbilical hernia. What's differential diagnosis? Have had 2 cesarean, 1 EXTREME dehisence, wound vac, revision surgery b/c not healing, PAIN

Hernia versus other. If I'm understanding correctly you had wound healing complications after you C-devotion. You still have pain and a non-healing wound wound? You could have a hernia, and the CT should show that. If not you mace have scar tissue or adhesions causing pain. Generally if a wound is chronic after surgery you would worry about infection or chronic irritation around a suture. .
