Study on the Clinical Effect and Safety of Single-hole Video-assisted Thoracoscopic Surgery Technique Combined with Iodine Tincture Mechanical Pleurodesis in the Treatment of Spontaneous Pneumothorax
Objective To study the clinical effect and safety of single-hole video-assistedthoracoscopic surgery (VATS) combined with iodine tincture mechanical pleurodesis in the treatment of spontaneous pneumothorax (SP).Methods A total of 62 patients with SP admitted to Yudu People's Hospital from September 2020 to August 2023 were selected and divided into single-port group (31 patients) and traditional group (31 patients) by random number table method. The single-port group was treated with single-port VATS+iodine tincture mechanical pleurodesis,while the traditional group was treated with traditional VATS+iodine tincture mechanical pleurodesis. The surgical efficacy,perioperative indexes (operation time,intraoperative blood loss,chest tube drainage time,postoperative drainage volume),blood gas indexes[arterial partial pressure of oxygen (PaO2),arterial partial pressure of carbon dioxide (PaCO2)]and postoperative complications were compared between the two groups.Results There was no significant difference in the excellent and good rate of operation between the two groups (P>0.05). The operation time and chest tube drainage time of the single-hole group were shorter than those of the traditional group,and the intraoperative blood loss and postoperative drainage volume were less than those of the traditional group (P<0.05). One day after operation,PaO2 increased and PaCO2 decreased in the two groups,and PaO2 in the single-hole group was higher than that in the traditional group,and PaCO2 was lower than that in the traditional group (P<0.05). The incidence of postoperative complications in the single-hole group was lower than that in the traditional group (P<0.05).Conclusion Single-hole VATS combined with iodine tincture mechanical pleurodesis is effective in the treatment of SP,which can reduce intraoperative bleeding,shorten the time of operation and chest tube drainage,improve the blood gas index of patients and reduce the risk of postoperative complications while ensuring the curative effect of operation.
