Evaluation of short-term and long-term results after laparoscopic antireflux surgery: esophageal manometry and 24-h pH monitoring versus quality of life index.

Purpose: The objective of this long-term study is to compare data on postoperative quality of life with objective functional measurements in patients with gastroesophageal reflux disease who have undergone laparoscopic antireflux surgery.

Methods: Between 1995 and 2005, 162 patients with gastroesophageal reflux disease underwent laparoscopic surgery. A minimum of 4 years after surgery, 60 patients were contacted at random, 29 of whom agreed to follow-up examination. The following examinations were performed preoperatively, 6 months postoperatively, and 4-12 years postoperatively: esophageal manometry, 24-h gastroesophageal pH-metry, and assessment of patient quality of life based on the gastrointestinal quality of life index (GIQLI).

Results: The number of postsurgical reflux episodes was reduced significantly, both at 6 months and at 4 or more years after surgery. The number of episodes dropped from 183 before surgery to 58 at 6 months after surgery and remained constant ≥ 4 years later. Surgery also produced a significant drop in reflux time, seen both 6 months and ≥ 4 years later. Six months after surgery, the median reflux time had fallen from 134 min (preoperatively) to 27 min, and at ≥ 4 years it was still significantly reduced at 35 min. Sphincter length (median preoperative length, 3 cm; median postoperative length (at 6 months and at ≥ 4 years), 4 cm) and sphincter pressure (median preoperative pressure, 3 mmHg; median at 6 months, 12 mmHg; median at ≥ 4 years, 10.9 mmHg) were significantly improved by surgery as well. Finally, surgery produced an improvement in quality of life. The median preoperative GIQLI was 102, while at 6 months after surgery it was 113 and at ≥ 4 years after surgery it was 124.

Conclusion: Laparoscopic fundoplication guarantees long-term improvement in symptoms and quality of life for patients suffering from gastroesophageal reflux disease. The effectiveness of reflux surgery can thus be demonstrated by long-term quality of life assessments and postoperative functional measurements. No statistically significant correlation between total score (DeMeester) and GIQLI could be demonstrated.
