A case–control study on early removal of thoracic drainage tube and gastric tube after MIE

Abstract

ObjectiveTo investigate the feasibility and safety of early removal of gastric tube and thoracic drainage tube after minimally invasive esophagectomy.MethodsA retrospective analysis was performed on 93 patients undergoing thoraco-laparoscopic assisted esophagectomy between January 2022 and September 2022. All patients were divided into two groups, the early group and the conventional group. The differences in drainage volume on the first day after operation, days of thoracic drainage tube indwelling, thoracic drainage tube replacement, incidence rate of pleural effusion, atelectasis, pneumothorax as well as pulmonary infection, respiratory insufficiency, and postoperative hospital stay were compared between the two groups. The criteria for thoracic drainage tube removal is the daily thoracic drainage volume of less than 250 ml in the early group. The gastric fluid volume on the first day after operation, the number of days of gastric tube indwelling, the rate of gastric tube replacement after removal, and the time of intestinal exhaust were compared between the two groups. In the meantime, the incidence of complications, such as anastomotic leakage and pulmonary infection, was observed in the two groups.ResultsThe removal time of gastric tube and thoracic drainage tube was significantly earlier in the early group than in the control group (P < 0.05). There was no significant difference in the gastric fluid volume and pleural fluid between the early group and the conventional group. P > 0.05), but there were significant differences in postoperative anastomotic leakage between the two groups (P < 0.05). There was no significant difference in the incidence of pleural effusion, atelectasis, pneumothorax, and pulmonary infection (P > 0.05), nor in thoracentesis rate and gastric tube replacement (P > 0.05). The postoperative hospital stay was significantly shorter in the early group than in the conventional group (P < 0.05)ConclusionThe early removal of the thoracic drainge tube and gastric tube is safe and effective, which does not increase the incidence of postoperative complications.
