Comparative study of the anatomic segmentectomy versus lobectomy for clinical stage IA peripheral lung cancer by video assistant thoracoscopic surgery.

Objective: The objective of this study was to compare the completely thoracoscopic anatomic segmentectomy with lobectomy to treat stage I_A peripheral lung cancer <2 cm. Materials and Methods: A retrospective study was performed that 54 cases stage I_A peripheral lung cancer patients were selected, including 26 cases of segmentectomy and 28 cases of lobectomy. We observed the operative time, blood loss, number of lymphadenectomy, post-operative chest drainage, hospital days, post-operative complications and mortality, post-operative recurrence and 3-year survival rate. Results: There was no significant difference about complications such as post-operative atelectasis, severe pneumonia, arrhythmia and cardiovascular/cerebrovascular in two groups (P > 0.05). The local recurrence rate was not significant different in two groups (P > 0.05). Two groups of operative time, blood loss and number of dissected lymph nodes was not statistically significant (P > 0.05), However, the difference was statistically significant in average chest drainage and less decreased pulmonary function, which led to patients received segmentectomy recovered faster and hospitalized less time (P < 0.05). We also found there was no significant difference on survival rate with 1 and 3 year follow-up of two groups (log-rank Chi-square = 0.028, P > 0.05). Conclusions: For stage I_A peripheral lung cancer, the thoracoscopic anatomic segmentectomy was safe and effective just as thoracoscopic lobectomy, and furthermore with faster post-operative recovery.
