This study found that the key factors affecting the efficacy of LF treatment in patients with e-GERD are acid reflux time, longest reflux time, number of refluxes longer than 5 minutes, and distal contractile integral. These factors influence the effectiveness of LF treatment.
Purpose To identify the factors that affect laparoscopic fundoplication (LF) treatment efficacy in patients with erosive gastroesophageal reflux disease (e-GERD) esophagitis, based on the findings of multichannel intraluminal impedance pH (MII-pH) and high-resolution manometry (HRM). Methods The subjects were 102 patients with e-GERD diagnosed by endoscopy, who underwent LF as the initial surgery. To analyze the findings of MII-pH and HRM, the patients were divided into two groups: a cured group (CR), comprised of patients whose esophagitis was cured postoperatively; and a recurrence group (RE), comprised of patients who suffered recurrent esophagitis. Results There were 96 patients in the CR group and 6 in the RE group. MII-pH indicated that the acid reflux time, the longest reflux time, and the number of refluxes longer than 5 min, were significantly higher in the RE group than in the CR group (p = 0.0028, p = 0.0008, p = 0.012, respectively). The HRM indicated that only the distal contractile integral (DCI) was significantly lower in the RE group (p = 0.0109). Conclusion The results of this study indicate that esophageal clearance may affect the treatment outcome of LF. Based on the findings of MII-pH, the longest reflux time and the number of refluxes longer than 5 min were important factors influencing the therapeutic effect, whereas based on the HRM, the DCI value was most important.
