[Longitudinal bronchotomy on the pars membranacea for endoscopic foreign body extraction]

Purpose of this paper is to report a case of foreign body obstructing the middle lobe bronchial origin, surgically removed through a longitudinal bronchotomy on the pars membranacea, reached by passing posteriorly to the lung. Anatomical considerations suggest that longitudinal bronchotomy on the pars membranacea of the main bronchial axis (stem bronchi, intermedius br (right), and lower lobar bronchus) gives direct visualization from inside also of foreign bodies sited into the lobar bronchi (sup, middle and lingula), allowing an easy bronchotomy repair, without lumen distortion or stenosis. Since the pulmonary artery is not in contact with this pars membranacea, broncho-arterial fistula in case of suture line dehiscence is quite improbable.
