The index of failure of the antireflux function of the cardia (IFAFC), as a criterion for the effectiveness of its videolaparoscopic correction for gastroesophageal reflux disease (gerd) in pthe index of failure of the antireflux function of the cardia after video-laparoscopic correction in gerd patients with hiatal hernia

Abstract

The purpose of the study was to create an index based on the total results of special research methods that characterizes the antireflux function of the cardia in the long term after its video-laparoscopic correction in GERD patients with hiatal hernia (HH). Long-term results of video-laparoscopic antireflux intervention in 213 patients with GERD and HH were analyzed. Based on the results of a remote survey and instrumental examination, the patients were divided into three groups. The first group consisted of the patients who had symptoms of GERD, but the presence of pathological gastroesophageal reflux was not confirmed by instrumental methods (122 patients, 57.3 %); the second group included the patients with recurrent GERD (19 patients, 8.9 %); the third group (72 patients, 33.8 %) consisted of the patients without GERD symptoms or its recurrence. To assess the antireflux function of the cardia in the long term after its video-laparoscopic correction, the index of failure of the antireflux function of the cardia (IFAFC) was developed based on the generalized results of instrumental research methods. Before surgery in all groups of the patients, the IFAFC did not have a statistically significant difference and indicated a very significant severity of signs of failure of the antireflux function of the cardia (0.70±0.06, 0.74±0.05, and 0.70±0.06, respectively; р>0.05). In the long term after surgery, the patients with false-positive GERD symptoms showed an improvement in the IFAFC by 87.14 % (p<0.001), the patients without symptoms of GERD and its recurrence — by 92.86 % (p<0.001), and the patients with recurrent GERD — by 16.22 % (p<0.05). The IFAFC allows assessing the results of the antireflux surgery. In the absence of recurrent GERD, the IFAFC is 0.05±0.01; in patients with recurrent GERD, it is 0.62±0.07. The IFAFC equal to 0.09±0.07 is typical for patients at risk with false-positive symptoms of GERD without confirmation of its relapse by special studies. These patients require follow-up.
