title: [Anatomical resection for liver metastases of the carcinoma of the large intestine and the rectum].
abstract: Resection of the colorectal carcinoma liver metastases is an effective therapeutical procedure with a five-year survival rate in 20-50% of the operated. Opinions on the most optimal type of the resection procedure remain to be controversial. The aim of this study was to assess all indication criteria for anatomical resections of the colorectal carcinoma liver metastases.
  
  
  METHODS
  This retrospective study analyzed 98 patients with liver resection for colorectal metastases. In 31 patients, extensive anatomical resections of the liver were conducted, segmentotomie were conducted in 20 patients and nonanatomical wedge resections in 47 patients. Extensive anatomical resections were conducted in cases of tumorous foci larger than 2cm and located marginally between individual segments of a single lobe, and in cases of multiple tumorous foci affecting a single liver lobe. The nonanatomical resections were conducted in cases of metastases smaller than 2 cm, localized on the liver surface or in cases of multiple peripheral foci, including cases when both liver lobes were affected.
  
  
  RESULTS
  In the group with the wedge-type resections, a histologically positive border was found in 4 cases. Postoperative complications were recorded in 10 (19.6%) patients with the anatomical resection and in 9 (19.1%) with the wedge resection.
  
  
  CONCLUSIONS
  1. Anatomical resection of the liver for the colorectal carcinoma metastases is indicated in cases of larger foci (over 2 cm), located marginally between segments or in multiple metastases affecting a single liver lobe. 2. Anatomical approach to the resection lowers the rates of histologicaly non-radical resections (R 1). 3. The new surgical technique of the liver transsection lowered, even in cases of anatomical resections, the postoperative morbidity rates.
