The adequacy of single-incisional thoracoscopic surgery as a first-line endoscopic approach for the management of recurrent primary spontaneous pneumothorax: a retrospective study

Background: Thoracoscopic surgery is a commonly used endoscopic surgical treatment approach in patients with primary spontaneous pneumothorax. The conventional thoracoscopic approach utilizes three or more small wounds for surgery. Currently, a single port approach is a potential alternative procedure in general thoracoscopic surgery. We investigated whether a single-port approach is suitable as a first-line endoscopic approach for all patients with primary spontaneous pneumothorax requiring surgery. Methods: From July 1st, 2008 to Dec 31, 2009, a total of 62 patients was included in this study. All the patients were admitted to our ward because they had surgical indications for surgery. Twenty-six patients underwent conventional three-port thoracoscopic surgery and thirty-six underwent single-port thoracoscopic surgery. All of the clinical data were analyzed retrospectively. Variables were compared and analyzed to determine the outcomes of the different surgical approaches. Results: The mean age of the 62 patients was 27.2 years. Forty-nine patients were men and thirteen patients were women. The mean time required for the operation was 61.6 minutes. There was one patient who had a recurrence in single-port group and 2 patients had a recurrence in three-port group during the period of follow-up. The average pain scores at 24 and 48 hrs after the operation were similar, but the pain scores at 72 hrs in the single-port group were better than the three-port group. There was no case that required conversion from a single-port to multiple wound approach in this study. There was no immediate postoperative recurrence. The follow-up duration was greater than 12 months. Conclusion: This study showed that single-port thoracoscopic surgery is a feasible and reasonable first-line endoscopic approach in the surgical treatment of primary spontaneous pneumothorax.
