title: [Thoracoscopy versus thoracotomy. The dilemma of the comparison and its meaning for quality assurance in thoracic surgery].
abstract: The need for scientific investigation into the benefits of thoracoscopy in comparison to thoracotomy as well as State intervention to assure quality in the field of surgery motivated the members of the commission of endoscopic surgery of the German Society of Thoracic Surgery to conduct a pilot project at their hospitals. This pilot project was expected to analyse data on the outcome and a selection of variables concerning trauma and postoperative quality of life of some 400 patients treated between 8/95 and 10/95 at 5 thoracic surgical clinics. On completion of the pilot project the course of 141 patients undergoing different thoracic operations at 4 thoracic surgery departments had been documented to various degrees. 60 patients for various indications received a thoracoscopy, 72 a thoracotomy. In 9 patients thoracoscopy was converted to thoracotomy (6.4%). Eight of the 141 patients died in the postoperative course (5.7%), overall morbidity was 15.6%. There was a slight but statistically not significant difference concerning mortality and morbidity in favor of thoracoscopy (1.7 vs. 9.7% and 10 vs. 19.4%). But, there was a selection of malignant diseases, higher age and high risk patients towards thoracotomy. In subgroups of patients undergoing operations not bigger than the resection of three lung wedges only time of operation and length of incision revealed to be significantly shorter for thoracoscopy (69(25-190) min vs. 128(24-240)min, p = 0.0013; 6(4-8)cm vs. 23(12-35)cm, p = 0.0001). Borderline significance was reached by the Spitzer-Index in advantage for thoracoscopy (8(2-10)points vs. 7(0-10)points, p = 0.0728). Thoracotomy and thoracoscopy are access procedures used with different indications in different patients. Differences concerning trauma and quality of life if present are marginal and will need studies to be outlined. Quality assurance in thoracic surgery using a standardized documentation will not succeed under the given circumstances.
