The early results of a prospective randomized clinical trial of selective proximal vagotomy with and without gastric drainage in a total of 36 patients are reported. In spite of adequate average acid reduction and little evidence of gastric retention two definite recurrent ulcers have occurred in the 16 patients who did not have a pyloroplasty. Further trials of the effect of selective proximal vagotomy without gastric drainage are necessary before the procedure is widely adopted. 相似文献

Two independent trials of selective vagotomy without the addition of a drainage procedure in the treatment of uncomplicated duodenal ulcer have shown that gastric stasis may occur after the operation and that in some cases this may be complicated by gastric ulcer. These findings do not support the contention that selective vagotomy alone allows normal gastric emptying. 相似文献

From January 1963 to December 1965 inclusive 192 men with duodenal ulcer were treated by elective truncal vagotomy and pyloroplasty with one death. Ten subsequent deaths were due to causes unrelated to the ulcer or operation, and 17 patients became untraceable. The remaining 164 patients have been followed up for five to eight years. The late results have been compared with those obtained in a previous study of patients five to eight years after truncal vagotomy and gastroenterostomy, truncal vagotomy and antrectomy, and subtotal gastrectomy respectively for duodenal ulcer.Of the various postgastric operation syndromes early dumping, late dumping, bilious vomiting, and diarrhoea were all less frequent, but not significantly so, after vagotomy and pyloroplasty than after vagotomy and gastroenterostomy.Recurrent ulceration was commoner after vagotomy and pyloroplasty than after all the other operations, the incidence of proved and suspected recurrent ulcers being respectively 6·7 and 7·3% after vagotomy and pyloroplasty, but only 2·5 and 5·9% after vagotomy and gastroenterostomy, 0 and 5·2% after vagotomy and antrectomy, and 0·9 and 3·7% after subtotal gastrectomy. The differences between vagotomy and pyloroplasty and vagotomy and antrectomy or subtotal gastrectomy are statistically significant, but those between vagotomy and pyloroplasty and vagotomy and gastroenterostomy are not.Overall assessment (Visick grading) of the outcome gave poorer results after vagotomy and pyloroplasty than after any other operation, with 14% of category IV cases after vagotomy and pyloroplasty, 11% after vagotomy and gastroenterostomy, 8% after vagotomy and antrectomy, and 6% after subtotal gastrectomy—differences that are significant between vagotomy and pyloroplasty and vagotomy and antrectomy or subtotal gastrectomy but not between vagotomy and pyloroplasty and vagotomy and gastroenterostomy.In the light of these findings it is suggested that truncal vagotomy and pyloroplasty has not lived up to expectations and its place as the currently most popular procedure in the elective surgical treatment of duodenal ulcer should be reconsidered. 相似文献

The results of surgical treatment for duodenal ulcer were compared in two groups of patients—51 who had undergone selective vagotomy without drainage and 17 who had had selective vagotomy and pyloroplasty. It is suggested that in the absence of organic pyloric or duodenal stenosis the former method seems both preferable and desirable, since postoperativley dumping does not occur and there is a steady improvement in gastric emptying. 相似文献

The pattern and rate of gastric emptying have been studied in 16 patients before and after vagotomy and pyloroplasty. The rate of emptying, expressed as half life in minutes, was not greatly changed by operation. After operation, however, there was a rapid initial phase of emptying, particularly marked in patients who had post-vagotomy diarrhoea. 相似文献

A retrospective survey of 4,026 patients having truncal vagotomy and pyloroplasty for duodenal ulceration showed a mortality rate of 1·4% (55 patients). On analysis the commonest causes of death were found to be bronchopneumonia 37% (18 patients) and sepsis 20% (10 patients). More than half of the deaths occurred in patients aged over 50. 相似文献

The results of elective truncal vagotomy and drainage in 547 duodenal ulcer patients are reported. Altogether, 204 patients were randomly allocated to pyloroplasty and 200 to gastrojejunostomy. In 101 patients gastrojejunostomy was electively chosen and in 42 patients the duodenum was opened to confirm the diagnosis. Operative mortality was 0·5%, the incidence of proved recurrent ulceration 3·3%, severe dumping 2%, and severe diarrhoea 1·1%. There were no significant differences between the groups, with the exception of bilious vomiting which occurred more often in patients with gastrojejunostomy. 相似文献

Seventy-three unselected patients with perforated duodenal ulcer were treated by vagotomy and pyloroplasty in a six-year period. Postoperative complications were commoner when the operation was carried out after more than six hours after perforation. The follow-up results were similar to those for elective vagotomy and pyloroplasty carried out in the hospital during the past nine years. 相似文献

Immediate postoperative results of vagotomy and pyloroplasty were compared with those of subtotal gastrectomy. Ulcer recurrence rate and the long-term complications of the two procedures were not studied. Age and sex distribution, and preoperative indications in the two groups of patients were almost identical. Vagotomy and pyloroplasty has gradually superseded subtotal gastrectomy at St. Michael''s Hospital, Toronto. One hundred and seventy vagotomy and drainage procedures were compared with 173 subtotal gastric resections performed over a five-year period. There were 39 postoperative complications and five deaths in the subtotal gastrectomy group, an overall mortality of 2.8% and an elective mortality of 2.4%. In the vagotomy and pyloroplasty group there were 31 postoperative complications and two deaths, an overall mortality of 1.2% and an elective mortality of zero. Vagotomy and pyloroplasty is a relatively safe procedure, associated with fewer complications, shorter hospital stay and a lower mortality than subtotal gastrectomy. 相似文献

The aim of this study was to investigate the incidence of piperacillin-specific drug antibody in patients with and without piperacillin. Piperacillin antibody was detected by piperacillin-induced hemolysis test kit. Three hundred samples were collected from patients who had been treated with piperacillin within 3 months; and 222 samples were from patients who were treated with other antibiotics; and a normal group of 120 samples was from healthy blood donors. The results showed that the positive rates in the piperacillin group, the other antibiotic group and the control group were 11.33%, 4.95% and 1.67%, respectively, which was statistically significant. The antibody titer was from 2 to 64. The antibody titer of the piperacillin group was significantly higher than that of the other two groups. The study suggests that piperacillin is able to induce piperacillin-specific drug antibody and drug antibody detection is useful for maintaining the safety of medication. 相似文献

Matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS) and electrospray ionization mass spectrometry (ESI MS) analysis of a 6x His-tagged recombinant form of rat mutant selenoprotein W (RMSW) reveals that aerobic growth conditions primarily produce a form of RMSW without bound glutathione (10,305 Da) whereas anaerobic conditions produce a glutathione-bound (305 Da) form (10,610 Da). Purification of RMSW was achieved with a procedure employing acetone precipitation and DEAE-cellulose chromatography, in addition to Ni-NTA agarose chromatography. Additional steps, including polyvalent metal ion binding (PMIB) resin chromatography and CM-cellulose chromatography, were necessary after elution from the Ni-NTA agarose column, in order to maintain solubility of the purified protein. 相似文献

The acridine dyes acridine orange (AO) and coriphosphine O (CPO) and ethidium bromide (EtBr) were used to stain bacterial digests after electrophoresis in native and denaturing (SDS) polyacrylamide gels and were shown to stain DNA and RNA preferentially over other subcellular components in the gels. Vegetative cell digests of Bacillus subtilis, Escherichia coli, Micrococcus luteus, and Staphylococcus aureus showed intense staining of DNA with AO and CPO near the top of the gel, but little or no staining of other cellular constituents. EtBr stained both DNA and RNA in the gels. Protein standards and non-nucleic acid cellular constituents stained faintly with high concentrations (> 100 μM) of AO, lower concentrations (13.9 μM) of CPO, and did not stain with 0.5 μg/ml EtBr in denaturing gels. The complete set of cellular biochemicals was visualized by silver staining, while the protein subset was detected by Coomassie blue staining. The highest concentrations of AO (120 μM) and CPO (13.9 μM) were shown to detect purified DNA in gels with a sensitivity in the range of 25–50 ng per band. This work demonstrates the specificity of acridine and ethidium dyes for nucleic acids, while illustrating the level of non-nucleic acid-specific interactions with other cellular components by staining of electrophoretically separated cellular components in a gel matrix. 相似文献

The presence of highly heat-resistant spores of Bacillus sporothermodurans in ultrahigh-temperature or sterilized consumer milk has emerged as an important item in the dairy industry. Their presence is considered undesirable since they hamper the achievement of commercial sterility requirements. By using a selective 30-min heat treatment at 100°C, 17 Belgian dairy farms were screened to evaluate the presence, sources, and nature of potentially highly heat-resistant spores in raw milk. High numbers of these spores were detected in the filter cloth of the milking equipment and in green crop and fodder samples. About 700 strains were isolated after the selective heating, of which 635 could be screened by fatty acid methyl ester analysis. Representative strains were subjected to amplified ribosomal DNA restriction analysis, 16S rRNA gene sequencing, percent G+C content, and DNA-DNA reassociations for further identification. The strain collection showed a remarkable diversity, with representatives of seven aerobic spore-forming genera. Bacillus licheniformis and Bacillus pallidus were the most predominant species overall. Twenty-three percent of the 603 spore-forming isolates proved to belong to 18 separate novel species. These findings suggest that the selective heating revealed a pool of unknown organisms with a higher heat-resistant character. This study showed that high spore counts can occur at the dairy farm and that feed and milking equipment can act as reservoirs or entry points for potentially highly heat-resistant spores into raw milk. Lowering this spore load by good hygienic measures could probably further reduce the contamination level of raw milk, in this way minimizing the aerobic spore-forming bacteria that could lead to spoilage of milk and dairy products. Assessment and characterization of this particular flora are of great importance to allow the dairy or food industry to adequately deal with newly arising microbiological problems. 相似文献
