[Selective bowel decontamination].

Infective complications play major role in mortality of high risk patients demanding intensive care. Selective Bowel Decontamination prevents endogenous infections by reducing the number of potentially pathogen microbes (aerobic bacteria, fungi) in the oropharynx and gastrointestinal tract, saving anaerobic bacteria. It had been used 20 years ago for the first time. Authors survey it's literature ever since. Selective Bowel Decontamination is performed by the mixture of antibiotics and antimycotic drug, administered orally in hydrogel, and suspension form in nasojejunal tube. The number of Gram negative optional aerobic bacteria and fungi decrease significantly in the gut, and the microbial translocation is following this tendency. Foreign authors achieved good results in acute necrotizing pancreatitis, after liver transplant, in polytrauma, in serious burn and in haematological malignancies. According to the literature Selective Bowel Decontamination shows advantages in selected groups of high risk surgical patients. In some studies the administration took few months, but the minimum time was one week. There was no report of increasing MRSA appearance. Regular bacteriological sampling is highly recommended in order to recognize any new antibiotic resistance in time.

[Emergency video-assisted thoracoscopic surgery for intrathoracic foreign bodies].

The aim of this retrospective study is to highlight the advantages of video-assisted thoracic surgery (VATS) in the assessment of thoracic trauma. In the past 4 years 3 patients had intrapleural or intrapulmonary Kirschner needles which penetrated from the site of a previous humeroscapular osteosynthesis and one patient with a gunshot projectile and haemothorax in the left thorax. They were treated by VATS removal of intrathoracic foreign bodies. No complications developed postoperatively, the chest wall pain was minimal, the duration of hospital stay (3-5 days) and recovery was short. The widespread use of minimal invasive VATS procedure is an alternative approach that provides safe and less invasive operation for acute chest trauma patients. We believe that its extended use for both diagnostic and therapeutic purposes even in some special circumstances is justified today.

Late complications of coloesophagoplasty and long-term features of adaptation.

OBJECTIVES: Revisional surgery of late complications after 141 substernal by-pass operations (1962-1990), except three cases with isoperistaltic (except seven with anisoperistaltic) transverse colon grafts for caustic esophageal strictures, are presented. Long-term adaptation of the grafts was investigated with cineradiographical and histochemical methods. METHODS: Correction of the "pseudodiverticulum" of the proximal anastomosis as a complication of the standard by-pass procedure (in five patients) was achieved by closure of the esophagus below the anastomosis or by end-to-end reanastomosis. Cervical anastomosis stricture (in seven) was solved either by plasty or resection and a similar reanastomosis. Delayed passage due to an intra-abdominal redundant graft (in five) was managed by abdominal shortening coloplication or by side-to-side gastrocolostomy. Late pyloric obstruction as a cause of gastrocolic reflux required pyloroplasty in two instances. Mixed barium-bread bolus for a cineradiographical transit study and periodic acid Schiff reaction plus Alcian Blue staining for a mucopolysaccharide search were used 8 years after the operations. RESULTS: In all but one case, redo surgery was successful. Characteristic coordinated multihaustral propulsive movement developed in the distal colonic segment, playing a secondary but active role in the final phase of swallowing in isoperistaltic substitution. These grafts were free from gastrocolic reflux. Augmentation of neutral mucopolysaccharide was observed on the surface and in the Lieberkühn glands of colonic mucosa. CONCLUSIONS: This experience attests that the majority of late complications following colonic esophageal substitution may be corrected by revisional surgery. The predominantly automatic propulsive movements of the isoperistaltically interposed grafts seem to provide an effective antireflux barrier against the gastrocolic reflux if some technical requirements (high gastric anastomosis, good gastric drainage, etc.) are respected. The graft mucosa showed signs of a positive adaptation. The best functional results were achieved by isoperistaltically interposed left colic transplants, which may be considered as an ideal graft (both technically and functionally) in extensive caustic strictures.
