INTRODUCTION: Impedance planimetry (FLIP) provides objective feedback to optimize fundoplication outcomes. Ideal FLIP ranges for differing wraps and bougies have not yet been established. We report FLIP measurements during fundoplication grouped by choice of wrap and bougie with associated outcomes.
METHODS: A retrospective review of a prospective gastroesophageal database was performed for all Nissen or Toupet fundoplication with intraoperative FLIP using an 8-cm catheter, 30-mL and/or 40-mL fill and/or 16-cm catheter, 60-mL fill. Surgeons used no bougie, the FLIP balloon as bougie, or a hard bougie. Outcomes included perioperative data, Reflux Symptom Index, GERD-HRQL, Dysphagia scores, need for dilation, postoperative EGD findings, and hernia recurrence. Group comparisons were made using two-tailed Kruskal-Wallis and Fisher's exact tests.
RESULTS: Between 2016 and 2022, 333 patients underwent fundoplication and intraoperative FLIP. Procedures included Toupet with hard bougie (TFHB, N = 147), Toupet with FLIP bougie (TFFB, N = 69), Toupet without bougie (TFNB, N = 78), Nissen with hard bougie (NFHB, n = 20), or Nissen with FLIP bougie (NFFB, N = 19). FLIP measurements at 30-mL/40-mL fills varied significantly between groups, notably distensibility index at crural closure (CCDI) and post-fundoplication (FDI). No significant differences in FLIP measurements were seen between those who developed poor postoperative outcomes and those who did not, including when grouping by choice of wrap and bougie. At a 40-mL fill, abnormal motility patients with CCDI > 3.5 mm2/mmHg developed zero postoperative dysphagia. TFFB abnormal motility patients with CCDI > 3.5 mm2/mmHg or FDI > 3.6 mm2/mmHg developed zero postoperative dysphagia.
CONCLUSION: Intraoperative FLIP measurements vary by fundoplication and bougie choice. A CCDI > 3.5 mm2/mmHg (40 mL fill) should be sought in abnormal motility patients, regardless of wrap or bougie, to avoid postoperative dysphagia. TFFB abnormal motility patients with FDI > 3.6 mm2/mmHg (40 mL fill) also developed zero postoperative dysphagia. FDI > 6.2 mm2/mmHg (40 mL fill) was seen in all postoperative hernia recurrences.
