One-port videothoracoscopic surgical intervention.

Background: One-port video-assisted thoracic surgery (VATS) has recently been proposed as an alternative to conventional 3-port VATS. To reduce pain, chest wall paresthesia, and hospital stay, lesser ports are the current direction.

Materials And Methods: From 2007 to 2010, 98 patients underwent 1-port VATS procedure. The charts were retrospectively evaluated. A 2.5 cm long incision was made at the sixth intercostal space in the median axillary line. A single flexible port was used. Both the camera and the endoinstruments were introduced through the port. Patient characteristics, visual analog score, and postoperative paresthesia scores were evaluated.

Results: The study enrolled 38 women and 60 men with the mean age of 49.1±1.5 years (range, 19 to 75 y). Thirty-one patients (28.6%) were diagnosed with malignant pleural effusion. Perioperative pleurodesis with talc was performed in 81% of them. One-port VATS approach was used for pleura biopsies in 77 (78.6%), wedge resection in 4 (3.8%), pleurectomy in 13 (12.4%), and biopsy with talc chemical pleurodesis in 4 (3.8%) instances. The mean operation time was 24.4 minutes (range, 15 to 50 min). No major cardiorespiratory or surgical complications were noted. The median observation time was 60 months (range, 36±81 mo). Among benign pathology patients, 56 (82.3%) of them did not complain about any pain; however, 12 patients had prolonged discomfort (2 pinprick, 6 numbness, and 4 pruritus).

Conclusions: One-port VATS in selected patients are feasible and seems to be safe in thoracic surgical interventions instead of conventional 3 ports that was presented in this series.
