Background/objective: Cosmetic factors are important when considering minimally
invasive surgery. For cosmetic improvement, a complete thoracoscopic lobectomy is accomplished
via the three-port two-instrument (TPTI) technique. The resected specimen is removed
without extending the port wounds. Only three wounds at 1.2 cm are used to finish the procedure.
Methods: From June 2012 to December 2013, 60 patients with lung cancer were to undergo lobectomy
and complete mediastinal lymph node dissection via the TPTI technique without an accessory
wound. The initial 28 cases (learning curve group) and the latest 28 cases were compared to
assess the learning curve.
Results: Excluding four cases of conversion, there were 28 cases in each group. There were no differences
between these two groups with respect to age, sex, tumor size, location of the lobectomy,
mean blood loss, mean postoperative drainage time, and mean hospitalization time
(p > 0.05). The mean surgery time significantly decreased, the mean number of lymph nodes
removed significantly increased, and the postoperative stage was significantly more advanced
in the latest 28 cases (p < 0.05). The conversion rate was similar in both groups.
Conclusion: Three-port complete thoracoscopic lobectomy with the two-instrument technique is
feasible for lung cancer treatment. The length of the learning curve consisted of 28 cases. This
TPTI technique should be popularized.
