Illeal conduit associated parastomal hernias: A novel laparoscopic top hat repair

Parastomal hernias (PH) are a well-known complication following ileal conduit urinary diversion. We present a case report of a woman in her mid-nineties with a symptomatic parastomal hernia at the site of her ileal conduit which was repaired laparoscopically by an inverted top-hat technique. The “top hat” is constructed by assembling a transected ring of synthetic mesh with a secondary mesh cylinder and laparoscopically securing this mesh construct in an underlay fashion. At eighteen months follow-up, the patient remains pain free and without evidence of hernia recurrence.
