再手術時に確認できた酸化再生セルロースシートの術後癒着防止の有効性

Usefulness of Oxidization-regenerated Cellulose Sheets in Preventing Postoperative Adhesion Confirmed at Second Surgery for Lung Cancer

酸化再生セルロースは，腹部手術において安全に癒着発生を減少させることが示されている1）．また，気胸再手術において酸化再生セルロースは周囲組織への癒着を起こしにくい．われわれは，区域切除術2年後に右肺下葉切除術を施行し，葉間部の癒着防止においても酸化再生セルロースシートが有効であった症例を経験したので報告する．

The patient was a 42-year-old woman who had been found to have a mixed ground glass opacity in the lung on chest computed tomography, and had underwent right S6 segmentectomy. At surgery, the plain between the upper and lower lobe was covered with a regenerative oxidized cellulose membrane. Two years later, multiple small shadows appeared in the remaining right lower lobe and completion right lower lobectomy was performed by thoracoscopy due to the adhesion to the absence of adhesion. Both of the histological examinations confirmed the diagnosis of minimally invasive adenocarcinoma of the lung. An oxidization regenerated cellulose sheet was effective in preventing postoperative adhesion in pulmonary resection.
