[Extragastrointestinal stromal tumor (EGIST)--a case review].

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract. Due to the presence of thyrosine kinase receptors within the tumor tissue, GIST is thought to originate from gastrointestinal pacemaker cells, the intersticial cells of Cajal. Tumors with the same morphological and imunohistochemical characteristics detected outside the gastrointestinal tract, are called extragastrointestinal stromal tumors (EGIST).

[An example of the liver metastases downstaging following chemoport implantation].

The case review describes a case of a patient, hospitalized with T3N0M1 carcinoma of the splenic flexure, with multiple metastases in the both liver lobes. The patient underwent left-sided hemicolectomy with cholecystectomy. Having considered the inoperable liver findings, a chemoport was implanted.

[Liver metastasis in colorectal carcinoma].

The authors describe the method and therapeutic results of liver metastases of colorectal carcinoma in a group of 14 patients followed up for 2 to 33 months. In these patients in five instances (35.7%) resection with subsequent intraarterial chemotherapy (HAI) was possible.

Carpal tunnel syndrome. Revision of the thenar motor branch?

This paper presents the authors' views and experience with operations of carpal tunnel syndrome. Because of the multifactorial etiology of the disease they cannot recommend a schematic solution using a single surgical procedure for the treatment of all patients. During an operation much depends on the local findings as well as on the neurological ones.

[Laparostomy--technical remarks].
