[A clinical study of lobectomy with minimally invasive incision].

Objective: To study the application of small thoracic incision for lobectomy with effects comparable to that of conventional incision.

Methods: A total of 386 patients with lung tumors were prospectively randomized into thoracic small incision group (n=184; average length of incision, 12.7 cm) and standard thoracic incision group (control group, n=152). The incision length, operation time, intra-operative bleeding volume, postoperative drainage volume, transfusion, hemostatic dosage, ambulation time, hospital stay and major complications were compared between the two groups.

Results: All of the indices in small incision group were significantly better than those of the control group (P<0.01) except the operation time (P>0.05). No severe complications occurred in small incision group, and in 4 cases conventional thoracotomy was performed instead due to adhesion or giant tumors.

Conclusions: Muscle-sparing thoracic small incision can achieve excellent clinical result and has such advantages as less invasiveness, reduced bleeding volume, pain and hospital stay, less complications, and better postoperative appearance. This procedure meets the requirements of lobectomy and provides an alternative for routine lobectomy for pulmonary tumors.
