| Description | We estimated the ideal intra-operative LESp increase to lie between 8 mm Hg and 20 mm Hg.Rearrangement of the study group patients into 3 subgroups was performed (A: LESp increase under 7,5 mmHg; B: LESp increase between 7,6-14,9 mmHg; C: LESp above 15 mmHg). There were not significant differences in the efficacy of antireflux surgery among the subgroups. There was a significant difference in the incidence of the persistent dysphagia between the subgroup C and the other two subgroups (p = 0,023 for the group A, p = 0,18 for the group B respectively) and A+B together (p=0,021). The highest risk of the persistent dysphagia was revealed in the subgroup C with the intraoperative LESp increase above 15mm Hg ( p = 0,001). The risk of the persistent post-operative dysphagia increased non-linearly with the LESp increase reaching its highest and stable value at 15mm Hg. The confidence intervals of this curve were too wide to make this functional dependence reliable. |
