Symptomatic, Radiological, and Quality of Life Outcome of Paraesophageal Hernia Repair With Urinary Bladder Extracellular Surgical Matrix: Comparison With Primary Repair.

INTRODUCTION: Paraesophageal hernia repairs are prone to recurrence and mesh reinforcement is common. Both biologic and prosthetic meshes have been used. We report a comparison of a new type of biologically derived graft, Gentrix Surgical Urinary Bladder Matrix (UBM). METHODS: The medical records of 65 patients who underwent paraesophageal hernia repair (PEHR) were reviewed. Primary data points included demographics, first-time or recurrent hernia, operative approach, graft or primary repair, operative time, and postoperative complications. Patients then underwent upper gastrointestinal series, completed the GERD-HRQL symptom severity questionnaire, and the SF-36 generic quality of life instrument. RESULTS: A total of 32 patients underwent graft-reinforced repair, 33 underwent primary repair. More patients in the UBM group were being treated for recurrent PEH. Demographic data and postoperative complications were similar. There was no difference in recurrence rates, size of recurrence, postoperative symptomatic or quality of life improvement. Patients who suffered recurrence in the primary repair group had more severe symptoms and a higher rate of dissatisfaction. Of the 3 patients with recurrences after Gentrix placement, reoperation demonstrated anterior failure where no reinforcement had occurred because of the posteriorly placed U-shaped graft. CONCLUSIONS: The use of UBM was not associated with an increased complications despite use in more difficult patients. Although there appeared to be no difference in recurrence rate or size, it was associated with less severe symptomatic recurrences. The U-shape configuration is prone to recurrence at the site of the repair not covered by the graft, suggesting that a keyhole configuration may be superior.

Reoperative fundoplications are effective treatment for dysphagia and recurrent gastroesophageal reflux.

With wide application of antireflux surgery, reoperations for failed fundoplications are increasingly seen. This study was undertaken to document outcomes after reoperative fundoplications. Sixty-four patients, 26 men and 38 women, of average age 55 years+/-15.6 (SD), underwent reoperative antireflux surgery between 1992 and 2003. Fundoplication prior to reoperation had been undertaken via celiotomy in 27 and laparoscopically in 37. Both before and after reoperative antireflux surgery, patients scored their reflux and dysphagia on a Likert Scale (0 = none, 10 = continuous). Reoperation was undertaken because of dysphagia in 16 per cent, recurrent reflux in 52 per cent (median DeMeester Score 52), or both in 27 per cent. Failure leading to reoperation was due to hiatal failure in 28 per cent, wrap failure in 19 per cent, both in 33 per cent, and slipped Nissen fundoplication in 20 per cent. Laparoscopic reoperations were completed in 49 of 54 patients (91%); 15 had reoperations undertaken via celiotomy. Eighty-eight per cent of reoperations were Nissen fundoplications. With reoperation, Dysphagia Scores improved from 9.5+/-0.7 to 2.6+/-2.8, and Reflux Scores improved from 9.1+/-1.4 to 1.8+/-2.7. Seventy-nine per cent of patients with reflux prior to reoperation, 100 per cent with dysphagia, and 74 per cent with both noted excellent or good outcomes after reoperation. We conclude that failure after fundoplication occurs. Reoperations reduce the severity of dysphagia and reflux, thus salvaging excellent and good outcomes in most. Laparoscopic reoperations are generally possible. Reoperative fundoplications are effective treatment for dysphagia and recurrent gastroesophageal reflux, and their application is encouraged.
