The use of biosynthetic mesh to enhance hiatal repair at the time of redo Nissen fundoplication.

OBJECTIVE: There are a number of reports in the literature describing the need for a redo fundoplication in patients who have previously undergone open fundoplication. However, these data are not well characterized in our current era of laparoscopic surgery. The purpose of this report is to document the management of patients requiring a redo fundoplication who originally underwent a laparoscopic Nissen fundoplication.

METHODS: After internal review board approval, the senior surgeon performed a retrospective chart review on all patients undergoing laparoscopic fundoplication between January 2000 and April 2006. Data collected included the patient's age, sex, neurologic impairment, need for gastrostomy, time interval between the initial and redo fundoplication, operative approach for the redo fundoplication, use of a biologic patch for the redo procedure, and length of follow-up.

RESULTS: Two hundred seventy-three patients underwent laparoscopic Nissen fundoplication by the senior author during this time interval. Twenty-one patients have required a redo fundoplication and repair of the enlarged hiatus after laparoscopic fundoplication. No patient has undergone a redo procedure without the development of transmigration of the fundoplication wrap. A redo operation was performed without mesh in 13 patients, of which there were 4 recurrences (31%). The other 8 cases were repaired with Surgisis (Cook, Inc, Bloomington, Ind), and none of these have recurred, with a minimum of 11 months' follow-up and a mean follow-up of 26 months. In the 4 patients requiring a second redo procedure, the enlarged esophageal hiatus was reinforced with Surgisis, and none of these cases have recurred, with a minimum of 3 years' follow-up.

CONCLUSIONS: Our data support the use of a biosynthetic mesh to reinforce the crural closure during the repair of iatrogenic hiatal hernias in children.
