Objective To explore the clinical effect of multi-groove silicone hose combined with monomial negative pressure drainage system in single utility lung cancer surgery.

Methods Clinical data of 200 patients who underwent single utility thoracoscopic lung cancer surgery at Changzheng Hospital, Naval Medical University from May 2018 to October 2019 were analyzed retrospectively. According to the different methods of postoperative thoracic drainage, the patients were divided into the conventional thoracic tube drainage group (thoracic tube group, n=100) and the multi-groove silicone hose combined with monomial negative pressure drainage group (new system group, n=100). The epidemiological and clinicopathological data of the two groups were compared before operation, and the clinical effect of thoracic drainage were compared after operation between the two groups.

Results There was no significant difference in age, gender, pathological type, and histological characteristics between the two groups. There were no serious perioperative complications such as pleural hemorrhage and bronchopleural fistula in the two groups. There was no significant difference in extubation time, hospital stay, and complication rate between the two groups. However, the incidences of pleural effusion and poor incision healing in the new system group were lower. Visual analogue scale (VAS) of the new system group was lower than that in the thoracic tube group at each postoperative interval (P < 0.05), and the frequency of analgesic drugs was lower in the new system group.

Conclusions The multi-groove silicone hose combined with the monomial negative pressure drainage system is better than the conventional thoracic tube drainage system in single utility thoracoscopic lung cancer surgery, and patients have high tolerance. Hence, it could be used as an alternative to thoracic drainage with thoracic tube after single utility lung cancer surgery.
