Abstract
BACKGROUND The study aimed to compare the patient-reported outcomes in patients who underwent early vs conventional feeding after thoracoscopic lung cancer resection. MATERIAL AND METHODS The study enrolled 211 patients who underwent thoracoscopic lung cancer resection at a tertiary hospital between July 2021 and July 2022. Patients were randomly assigned to the conventional group or the early feeding group. There were 106 patients in the early feeding group and 105 patients in the conventional group. The conventional group received water 4 h after extubation and liquid/semi-liquid food 6 h after extubation. In contrast, the early feeding group received water 1 h after extubation and liquid/semi-liquid food 2 h after extubation. The primary outcomes were the degree of hunger, thirst, nausea, and vomiting. The secondary outcomes were postoperative complications, duration of hospital stay, and chest tube drainage. RESULTS No differences were found between the 2 groups in the degrees of postoperative nausea, vomiting, or pain after extubation for 1, 2, 4, and 8 h. Postoperative complications, duration of chest tube drainage, and duration of hospital stay were also similar (P=0.567, P=0.783, P=0.696). However, the hunger and thirst scores after extubation for 2 h and 4 h decreased and were lower in the early feeding group (both P<0.001). No patients developed choking, postoperative aspiration, gastrointestinal obstruction, or other complications. CONCLUSIONS Early oral feeding after thoracoscopic lung cancer resection is safe and can increase patient comfort postoperatively.
