Introduction: Preoperative inspiratory muscle training (IMT) can minimize the occurrence of complications after esophagectomy. Objective: To evaluate the effects of preoperative IMT in patients undergoing esophageal surgery by determining respiratory muscle strength (PImax and PEmax), pulmonary function (FEV1, FVC, FEV1/FVC) and functional capacity by the 6-minute walk test (6MWT). Methods: Twenty-two patients were randomized into two groups: a control group (CG; n = 10) and an intervention group (IG; n = 12). Only IG performed IMT for a minimum period of 2 weeks. The assessments were conducted pre- and post-surgery. Results: An increase of PImax was observed in IG, but not in CG, in the second preoperative assessment (p = 0.014). Assessment on postoperative day 1 showed a reduction in maximal respiratory pressures in the two groups, but the reduction was more marked in IG (p < 0.05). Partial recovery of the variables evaluated was observed at discharge in the two groups. These variables had fully returned to initial values on postoperative day 30. The distance walked in the 6MWT was greater in IG, but the difference was not significant (p = 0.166). There was no difference in the frequency of pulmonary complications between groups. Conclusion: Preoperative IMT performed in our study improved inspiratory muscle strength but did not influence the postoperative pulmonary function or functional capacity of patients undergoing esophagectomy.Downloads
