title: [Stump consolidation after video-assisted thoracoscopic segmentectomy].
abstract: Pulmonary segmentectomy by video-assisted thoracic surgery (VATS) is used for minimally invasive surgery for removal of small lung neoplasms, and stump consolidation is one of the potential postoperative complications. The objective of the present study is to clarify the incidence of stump consolidation and its predictive factors by assessing patients who underwent VATS segmentectomy in our department. Stump consolidation was defined as atelectatic lesions along the surgical stump with >10 mm thickness in horizontal sectional view by computed tomography, at least 3 months after surgery. Between February 2007 and September 2010, 70 patients (38 men and 32 women) with primary lung cancer (43 patients) and metastatic pulmonary tumor (27 patients) underwent VATS segmentectomy. Stump consolidations were seen in 7 patients. Univariate analysis showed the significant difference for the period of performed operation. Left-sided operation, especially segmentectomy of left S(1+2), was another predictive factor, though not significant. Stump consolidation after VATS segmentectomy can be deueloped by conbined workspace for stapling and misidentification of intersegmental plane. When division of the intersegmental plane is difficult, open thoracotomy should be undertaken to prevent such compliance.
