OBJECTIVE: Recently, single-port video-assisted thoracic surgery (VATS) has been proposed as an alternative to conventional three-port VATS for bullectomy/blebectomy for primary spontaneous pneumothorax. The aim of this study is to evaluate the feasibility of single-port VATS for primary spontaneous pneumothorax.
METHODS: VATS was performed for primary spontaneous pneumothorax in 40 patients from March 2011 to June 2012. We reviewed the medical records of these 40 patients, retrospectively.
RESULTS: Eighteen patients underwent conventional three-port VATS (three-port group) and 22 patients underwent single-port VATS (single-port group). The mean age of patients was 19.8 years in three-port group and 21.6 years in single-port group. The mean operation time was 40.3 minutes in three-port group and 42.5 minutes in single-port group. There was no difference in number of wedge resection, amount of chest tube drainage, operation time and postoperative pain between both groups. The mean length of chest tube drainage and hospital stay were shorter in single-port group than three-port group. These differences were statistically significant. There were less postpoerative paresthesias in single-port group than three port group (p=0.04). There was postoperative recurrence of pneumothorax in one patient in three-port group and two patients in three-port group. There was no significant difference between two groups, statistically.
The median size of surgical wound was 2.0cm (range, 1.5-2.5) in single-port group.
CONCLUSIONS: In our study, single-port VATS and three-port VATS for primary spontaneous pneumothorax offered similar result. There were many advantages in length of drainage, hospital stay, postoperative paresthesia and cosmetic result in single-port group compare to three-port group. In well selected patients, single-port VATS would be considered for primary spontaneous pneumothorax.
