[The influence of thoracotomy and laparotomy on the chest wall movement].

The influence of thoracotomy and laparotomy on the chest wall movement was examined using newly produced 6-channeled linear magnetometer. Two groups (one is the group of the patients who had undergone thoracotomy and laparotomy for esophageal cancer and the other is the group of the patients who had undergone laparotomy) were examined 2 to 8 weeks after operation. The chest wall movement was restricted analward at the operative wound of the chest wall. The other points had no remarkable restriction. From the view point of the chest wall movement this study shows thoracotomy and laparotomy at the same time and only laparotomy had almost the same influence.
