Influence of Wrap Fixation Technique on the Results of Fundoplication

Different techniques of wrap fixation in laparoscopic Nissen fundoplication (LNF) have been proposed with of the aim to reduce the complications, but the optimal technique is yet to be determined. The aim of our prospective study was to evaluate several techniques of wrap fixation and determine whether the application of a combined approach to perform wrap fixation reduces the failure rate in short-term and long-term follow-up.

One hundred two patients with sliding or paraesophageal hiatal hernia (type I or type II), who underwent antireflux surgery were randomized into 2 groups. In group I, LNF was supplemented with suturing the wrap to the diaphragmatic crura (35 patients) or to the body of stomach (16 patients). This was dependent on the strength of the crura (defined as weak or strong). The control group (51 patients) underwent LNF without wrap fixation. All patients were assessed using a validated symptom and quality of life (gastroesophageal reflux disease-Health Related Quality of Life) questionnaire, 24-hour impedance-pH monitoring, and barium swallow.

At the 48-month follow-up, the overall rate of complications was not significantly different between the 2 groups; however, there was a tendency toward a lower frequency of reoperations in the first group (P=0.059). Fixation of the fundoplication of wrap was noted to lead to significantly lower rates of postoperative dysphagia (P<0.05). These patients (group I) were also found to have significant improvement in gastroesophageal reflux disease-Health Related Quality of Life score (from 19.3±13.2 to 4.3±3.9 vs. from 18.7±11.9 to 9.3±7.7).

Fixation of the Nissen fundoplication wrap has been shown to have a positive impact on the reduction of postoperative dysphagia and leads to an improvement in disease-specific quality of life.
