Background
Long-term results in antireflux surgery may depend on fundoplication type and wrap length. We compared the outcome of two different wrap lengths among the patients undergoing partial or total fundoplications. This study is the next part of a prospective 5-year follow-up assessment.
Methods
A total of 153 patients were randomized to Nissen or Toupet 1.5- or 3-cm wrap laparoscopic fundoplication. The primary endpoint—treatment failure rate was defined as a recurrent GERD or persistent dysphagia. Intensity of heartburn, dysphagia, gas-bloating, presence of esophagitis were assessed as a secondary outcome at 1-year and 5-year follow-up.
Results
At 5-year follow-up, data were collected from 129 (85 %) patients. At 1-year follow-up, 17 (11 %) treatment failures were detected. At the end of the fifth year, the numbers reached 23 (15 %). The failures were more common in the 1.5-cm Toupet (25 %) and the 3-cm Nissen group (18.2 %). The significant difference in failure rates was found between 1.5-cm and 3-cm Toupet groups (P < 0.05). Dysphagia remained low during the follow-up in all of the groups. The prevalence of higher scores of heartburn after 5 years was detected in Nissen 1.5-cm group (20.8 %). The lowest scores were observed in Toupet 3-cm group. Bloating symptoms were more prevalent among Nissen and Toupet 3-cm group patients at 5-year follow-up. At the end of the fifth year, the prevalence of esophagitis was lower in Nissen 1.5-cm (19.3 %) and Toupet 3-cm (13.3 %) groups. The highest prevalence of esophagitis—32.4 %—was found in Toupet 1.5-cm group.
Conclusions
Nissen and Toupet fundoplication achieved sufficient control of reflux with success rate of 85 % at 5-year follow-up. There were no significant differences in the postoperative dysphagia, esophagitis, and bloating rates. However, the distribution of treatment failures leads us to conclude that 1.5-cm wrap length is insufficient in cases of posterior partial fundoplication.
