BACKGROUND There are several well-known procedures to treat abdominal wall hernias, but the results are quite controversial. The aim of study was to compare the results of different surgical modalities - mesh (onlay vs. sublay position) and suture repair - in the treatment of abdominal wall hernias. METHODS A five-year randomized, multicentric,(More)
BACKGROUND Cancer of the colorectal region is the second most frequent cause of death among malignant diseases. The influence of two allelic polymorphisms of GSTM1 and GSTT1, and that of p53 gene codon 72 on colon cancer was investigated. PATIENTS AND METHODS Intraoperatively removed tissue samples were processed from colorectal cancer patients.(More)
BACKGROUND Surgical site infections (SSI) are the third most common hospital-acquired infections and account for 14% to 16% of all such infections. In elective colorectal operations, the international SSI rate ranges from 4.7%-25%. In a previous retrospective study in this department, the SSI rate was unacceptably high (25%), and the promising different(More)
Cold preservation prior to small bowel transplantation can moderate tissue oxidative injury. This stress triggers several intracellular pathways via mitogen activated protein (MAP) kinases. MAP kinases include the extracellular signal related kinase (ERK), c-Jun N-terminal kinase (JNK), and p38 MAP kinase. Pituitary adenylate cyclase-activating polypeptide(More)
Tissue injury caused by cold preservation and reperfusion during small bowel transplantation remains an unsolved problem. Increasing evidence suggests that pituitary adenylate cyclase-activating polypeptide (PACAP) has protective effects in several ischemia-reperfusion (I/R) models. This study investigated the effect of PACAP-38 on oxidative stress in(More)
OBJECTIVE Applicability of harmonic scalpel in lung biopsy was investigated in a randomised single institute study. METHODS Safety of the method, morbidity, drainage duration and in-hospital stays were compared in two randomised groups of patients in which either ultrasonic harmonic scalpel (n:20) or endostapler (n:20) were used for pulmonary biopsies(More)
Chronologically, complications can be classified as intraoperative, early, and late. The authors analyze complications according to this classification on the basis of more than 400 esophageal operations and related literary data. As regards intraoperative complications, they deal only with those occurring at transhiatal esophagectomy (e.g., tracheal tear,(More)
BACKGROUND AND STUDY AIMS In 1981, the authors introduced balloon catheter dilation for postoperative gastric outlet stenosis and later for peptic, corrosive and postvagotomy gastric outlet stenosis. This retrospective study evaluates the effectiveness, safety and outcome of balloon catheter dilation in these various indications. PATIENTS AND METHODS(More)
Laparoscopic removal of normal and moderately enlarged spleens has become the gold standard operation in recent years because its short operative time, technical safety, and quick patient recovery time. The best method for extraction of the removed spleen, however, has not yet been determined. The authors present a new method for the extraction of the(More)
AIMS Three gastrointestinal autonomic nerve tumours (GANT) were characterized by immunohistochemistry and flow cytometry. Two of the three cases occurred in the small intestine, while the third was found in the stomach. Besides the immunohistochemical and ultrastructural description, the aim of this study was to examine the relation between the known and(More)
