Thoracoscopic segmentectomy for intralobar sequestration in adult: a case report

BACKGROUND: Surgical resection is the first choice for intralobar sequestration (ILS). A lobectomy is often performed, though we consider that a segmentectomy may be sufficient for benign cases if the sequestration is completely included within a segment. CASE PRESENTATION: We treated a 36-year-old female diagnosed with ILS. Chest computed tomography (CT) revealed several cystic lesions with niveau formation and consolidation in left segment (S)10 without communication of the bronchus and abnormal artery branching from the descending aorta. We performed a sublobar resection of left S10 including sequestration through a thoracoscopic minimally sized incision. The sequestration had dark red appearance and was completely included in the S10. The boundary line of S10 was clear with inflation of the lung after cutting bronchus 10. The postoperative course was uneventful. Chest CT findings at 2 years after surgery showed good expansion of the residual left lower lobe with no consolidation and respiratory function were nearly the same as the preoperative condition. CONCLUSIONS: A thoracoscopic segmentectomy for ILS is a feasible and useful procedure for qualified cases, even in adult patients who had repeated inflammation.
