In March 2007, under the guidance of the Ministry of Health, Labour and Welfare, a committee released Japanese guidelines for cardiopulmonary bypass (CPB) with the purpose to standardize CPB hardware and software for patient's safety and education of medical personnel. In April 2007, the Japanese Society of Extra Corporeal Technology in Medicine (JaSECT) released recommendations concerning safety devices for cardiopulmonary bypass. An on-site training session for CPB troubles was held at the 38th annual meeting of Japanese Society for Cardiovascular Surgery in February 2008 as a measure to ensure safety of CPB. ⋯ Of the 7 certified or uncertified perfusionists who participated, only one certified perfusionist made an effort to accomplish the recommendation. CPB accidents are rare, but as a medical team, tragedies such as death and life-threatening complication due to CPB accident should be prevented at all costs. We believe that the 1st step to prevent CPB incident is to read and understand the CPB guidelines thoroughly, and to accomplish the "required" items listed in the recommendations.

Eighty-six cases of small peripheral lung cancer without contact with the chest wall on computed tomography (CT) scans were studied on the presence of radiological pleural indentation and pathological pleural invasion. Twenty-three tumors in 44 cases with pleural indentation were found to reach the pleura histologically, but only one in 42 cases without pleural indentation. ⋯ Pleural indentations were more frequently seen in small adenocarcinomas of low ground-glass opacity (GGO) ratio or Noguchi's type C. Small lung nodules with pleural indentation had better be removed as early as possible because of the possibility of pleural invasion and pleural dissemination.
