Impact and effect of preoperative short-term preoperative pulmonary-related training on patients with gastric cancer: a randomized controlled single center trial.

[PURPOSE] This study aimed is to evaluate the impact of pre- and postoperative pulmonary-related training, including respiratory and aerobic training, on postoperative pulmonary complications (PPCs) after radical resection of gastric cancer (GC).

[METHODS] We conducted a randomized controlled trial of 121 participants who received a systematic, comprehensive, high-intensity pulmonary exercise regimen for 5 days preoperatively and at least 5 days postoperatively. The control group received standard preoperative care. We analyzed the occurrence of PPCs in both groups as the primary outcome RESULTS: A total of 43 of 121 participants (35.5%) were diagnosed as having PPCs, and the incidence of PPCs was markedly lower in the training group than in the control group (26.2% [16 of 61] vs 45.0% [27 of 60]; P = .031). Moreover, the duration of the postoperative hospital stay was shorter in the training group (8.69 ± 1.92 days) than the control group (9.57 ± 2.16 days; P = .020) and reduced hospitalization costs, amounting to €9605.1 ± €2556.26 in the training group and €10,594.6 ± €2560.7 in the control group (P = .035).

[CONCLUSION] Our study established that a perioperative pulmonary-related training notably diminishes the incidence of PPCs, curtails the duration of hospitalization, and mitigates hospitalization expenses for patients undergoing GC surgery.
