Background:
This study aimed to determine the usefulness and limitations of videoassisted thoracoscopic (VATS) lobectomy using one-window and puncture method (1WPM).
Methods:
This study involved 14 patients who underwent lobectomy using the 1WPM at our institute from 2008 to 2017.
Results:
The study patients comprised of 3 men and 11 women with a median age of 10.5 years (range, 0-72 years). There were eight cases in children younger than 18 years old and the youngest patient was 9 days old. The diagnoses were congenital pulmonary cystic disease (n = 7), primary lung cancer (n = 4), metastatic lung tumor (n = 1), and others (n = 2). The 1WPM was successful in 9 of 14 patients (64.3%) and, in 5 cases (35.7%), needed conversion to either two-window method (TWM) using additional port (n = 3) or open thoracotomy (n = 2). The causes for conversion were need for additional bronchoplasty or lymph node dissection (n = 3), failure of one-lung ventilation (n = 1), and presence of a small thoracic cavity that made the procedure extremely difficult (n = 1). In the group that was successfully treated with 1WPM, the median values were as follows: operation time, 193 min (range, 112-480 min); blood loss, 0 ml (range, 0-90 ml); drainage duration, 1 day (range, 1-4 days); and postoperative hospital stay, 7 days (range, 4-13 days).
Conclusions:
Lobectomy by 1WPM can be safely performed and has good postoperative course and this procedure can be applicable and effective in small infants.
Insights
Video-assisted thoracoscopic surgery (VATS) lobectomy using the one-window and puncture method (1WPM) is a safe and effective procedure, particularly for infants. While successful in most cases, conversion to other methods may be necessary for complex situations.
Area of Science:
- Thoracic Surgery
- Minimally Invasive Surgery
- Pediatric Surgery
Background:
- Video-assisted thoracoscopic surgery (VATS) is a key minimally invasive technique.
- The one-window and puncture method (1WPM) is a specific VATS approach.
- Evaluating the utility of 1WPM for lobectomy is crucial.
Purpose of the Study:
- To assess the efficacy and limitations of VATS lobectomy using the 1WPM.
- To determine the safety and applicability of 1WPM in a diverse patient group, including infants.
Main Methods:
- Retrospective analysis of 14 patients undergoing lobectomy via 1WPM between 2008 and 2017.
- Inclusion of pediatric and adult patients with various pulmonary conditions.
- Documentation of conversion rates and reasons for conversion to alternative surgical methods.
Main Results:
- The 1WPM was successful in 64.3% of cases (9/14 patients).
- Conversion to two-window method or open thoracotomy was required in 35.7% of cases due to surgical complexity or technical challenges.
- Successful 1WPM cases showed favorable outcomes: median operation time 193 min, 0 ml blood loss, 1-day drainage, and 7-day hospital stay.
Conclusions:
- Lobectomy using the 1WPM can be performed safely with good postoperative results.
- The 1WPM is a viable and effective option for lobectomy, even in very young infants.
- Careful patient selection and surgeon experience are important for optimizing 1WPM outcomes.
