Background: The significance of the free radicals is emphasized in the pathophysiology of diabetes and the progression of chronic diabetic complications. Smoking cigarettes increases the risk of developing type II diabetes and intensifies pathophysiological processes during the development of type I diabetes. Tobacco smoke is also additional source...

Schwannoma is a tumor formed of spindle cells that arise from the nerve plexus Schwann sheath cells of the gastrointestinal tract wall. It appears to be rare among the tumors of the gastrointestinal tract (GIT) and occurs mainly in the stomach, representing only 0.2% of all cancers of the stomach. It is usually a benign and slow growing tumor, and...

Androgen insensitivity syndrome (AIS) is a congenital disorder in which a defect in the androgen receptor (AR) gene leads to cellular resistance to androgens. Defects in the AR gene, located on the X chromosome, result in the development of a feminine phenotype in chromosomally male (46, XY) individuals. In this case report, we present a 44 years o...

Negative pressure wound therapy (NPWT) has become a standard in the treatment of chronic and difficult healing wounds. Negative pressure wound therapy is applied to the wound via a special vacuum-sealed sponge. Nowadays, the endoscopic vacuum-assisted wound closure system (E-VAC) has been proven to be an important alternative in patients with upper...

Zenker diverticulum (ZD) is the most common type of diverticula of the esophagus. Most often refers to men with a peak incidence in the seventh and eighth decade of life. In the majority diverticula remains asymptomatic and in patients with symptomatic course of the disease symptoms are often nonspecific. Aim of the study was to present the authors...

Peritoneal adhesions, the fibrotic bands that form between the surfaces in the peritoneal cavity following surgery, still pose a difficult clinical challenge. To evaluate the SprayShield™ Adhesion Barrier System (PEG ester amine solution and a buffer solution) in reducing post-operative adhesion formation. This was a prospective, multi-center, rand...

The authors present a 32-year-old male patient with incarceration of a recurrent esophageal hiatal hernia after laparoscopic repair. A life-threatening strangulation of the stomach and the transverse colon occurred within a few days after the operation. Relapse of hiatal hernias amounts to almost half of early complications characteristic for the l...

Vacuum-assisted closure (VAC) therapy is a widely acknowledged method for chronic and traumatic wound healing. The feasibility of VAC therapy used for the treatment of intestinal fistulas is still a subject of debate. Complex postoperative wounds pose significant therapeutic problems, especially when there are several fistula openings in the wound...

The aim of the study was to compare the results of treatment by local excision of two different clinical stages of the rectal cancer. Fifty-eight patients with early rectal carcinoma were operated on during the last 26 years using different methods of local excision. The carcinomas were initially assessed as not-exceeding the muscularis layer of th...

Aim of the study was to present the development of methods and results of local rectal carcinoma excisions during the last 26 years. Material and methods. The study group comprised 58 patients with rectal carcinoma initially assessed as non-infiltrative. The tumors, localized 12 cm from the anus margin, were removed by means of "parachute" excision...

The aim of the study was endoscopic and histological evaluation of mucosal inflammatory changes in the ileal reservoir after restorative proctocolectomy with ileoanal anastomosis (IPAA) because of FAP (27 patients) and ulcerative colitis (34 patients). Endoscopic symptoms of pouchitis (edema, granularity, contact bleeding, loss of vascular pattern,...

At present, endoscopic polypectomy is a routine procedure. It is due to the theory, which claims polyps to be premalignant lesions in the development of colorectal cancer and so their removal should prevent the fatal disease. Endoscopic polypectomy was performed in 1204 patients. In all of them complete colonoscopy with the removal of all encounter...

Transanal Endoscopic Microsurgery (TEM) was introduced to clinical practice by Buess in 1983. After several years of gaining experience technique has been used for the excisions of rectal tumours. TEM enables excisions of the tumours localised in the rectum and distal portion of the sigmoid colon from 5 to 25 cm from the anal verge. Until now 13 pa...

The paper presents the operation of local excision of a rectal polyp using TEM technique. The operation was performed at our Department on the 12th of April 1996 with the instruments for transanal endoscopic microsurgery made by Wolf Company according to professor Buess. The patient was 49 year old woman, in whom rectoscopy revealed at 8 cm above t...

The authors discuss 56 patients operated for rectal cancer primarily estimated as noninvasive. Applied procedures were: local excision through stretched anus /46 cases/, Localio technique /6 cases/, rectotomy during a laparotomy /1 case/ and Transrectal Endoscopic Microsurgery /3 cases/. The patients were divided into 3 groups according to tumor's...

Transanal can be performed with excision of rectal tumors the TEM technique (Transanal Endoscopic Microsurgery) and the conventional transanal method. TEM was introduced to clinical practice by Buess in 1983. The lesions within the rectum are visualized through the rectoscope with 40 mm diameter, connected to the CO2 insufflator and stereoscopic op...

The aim of this study was to compare therapeutic efficacies of drugs which decrease portal pressure: octreotide (somatostatin analogue), vasopressin and balloon tamponade in cases of bleeding from esophageal varices. Octreotide was administered in 21 patients in continuous intravenous infusion of 50 μg/h for 48 h, vasopressin in 12 patients in the...

The integrity of stapled anastomoses was controled upon completion in 118 patients. Intraoperatively leakage was demonstrated in 10 cases. In 4 patients it was due to partial or total anastomosis dehiscence. In those cases the reconstruction of the low anastomosis had to be performed by hand suturing. The stumps were reanastomosed either from the a...
