title: [New operative technic for resecting cardiac cancers with dissection of the lower mediastinal lymph nodes through transabdominal phrenotomy using an improved hook suspender and an autosuture surgical stapling instrument].
abstract: To obtain a sufficient operative field at the operation for cardiac cancer, especially with esophageal infiltration, thoracotomy or sternotomy has been added to laparotomy. These procedures are not easy and cause great stress in patients. Through our new technique, left sided thoracotomy and sternotomy can be eliminated in favor of transabdominal phrenotomy, which is able to be performed much easier to obtain a good operative field. In order to perform the phrenotomy, the diaphragm has to be stretched using our modified hook suspender, by which the costal arch is lifted strongly upward and cranially. With these procedures, about a 5cm long esophagus is able to be resected with lymph node dissection in the lower mediastinum without difficulty. No marked influence of the hook suspender as well as the phrenotomy has been recognized on respiratory and circulatory systems. The anastomosis between the esophagus and jejunum or residual stomach seems to be very difficult, because the site of the anastomosis is located quite deep in the mediastinum. This problem, however, can be completely resolved by means of a surgical stapling autosuture instrument.
