Influence of various proton pump inhibitors on intestinal metaplasia in noneradicated Helicobacter pylori patients 总被引:1,自引:0,他引:1

AM: Intestinal metaplasia (IM) is more often found in patients with Helicobacterpylori(Hpylori) infection, while eradication of H pylori results in significant reduction in the severity and activity of chronic gastritis. We aimed to determine in patients with unsuccessful eradication of Hpylori the role of various proton pump inhibitors (PPIs) having different mechanisms in the resolution of IM. METHODS: We confirmed endoscopically and pathohistologically (Sydney classification) the IM in 335 patients with gastritis before and after medication for eradication of H pylori (Maastricht Protocol 2002). H pylori infection was determined by using histology, urease test and culture. Control endoscopy and histology were done after 30 d and thereafter (within 1 year). Unsuccessful eradication was considered if only one of the three tests (histology, urease and culture) was negative after therapy protocol. We used omeprazole, pantoprazole, lansoprazole in therapy protocols (in combination with two antibiotics). RESULTS: We found no significant difference in resolution of IM by using different PPI between the groups of eradicated and noneradicated patients (P<0.4821 and P<0.4388, respectively). CONCLUSION: There is no significant difference in resolution of intestinal metaplasia by different proton pump inhibitors. 相似文献

Purpose
Only a few series of patients with a spigelian hernia managed on an outpatient basis have been reported in the literature. The aim of this prospective study was to evaluate the results of the elective spigelian hernia repair as an ambulatory procedure.Methods
From June 2007 to June 2010, 8 patients with 9 spigelian hernias were electively operated on under local anesthesia as a day case. Four patients had unilateral spigelian hernia, 1 had spigelian and inguinal on the same side, 1 had spigelian and epigastric, 1 had spigelian and umbilical, and 1 patient had bilateral spigelian and umbilical hernia. Spigelian hernia was managed by the “open preperitoneal flat mesh technique.” In patients with several ventral hernias at different sites, “the open preperitoneal flat mesh technique” was performed using one separate flat mesh for each of the hernias; for the patient with inguinal hernia, the Lichtenstein procedure was performed in addition.Results
No complications and recurrences were recorded during a mean follow-up of 23.5 months (range: 11–35).Conclusion
The elective spigelian hernia can be successfully repaired under local anesthesia as a day-case procedure. The “open preperitoneal flat mesh technique” provides excellent results under these conditions. 相似文献5.
BACKGROUND/AIMS: Intraoperative blood loss is still a major concern for surgeons operating on the liver since it is associated with a significantly higher rate of postoperative complications and shorter long-term survival. An original radiofrequency (RF)-assisted minimal blood loss technique for transecting liver parenchyma is presented. METHODS: In a prospective study, starting November 2001 and ending December 2005, a total of 90 RF-assisted liver resections were done. Pre-cut coagulative desiccation was produced by the Cool-tip (Valleylab, Tyco) water-cooled, single, RF tumor ablation electrode connected to a 480-kHz 200 W generator (Valleylab Cool-tip RF System). Vascular occlusion techniques and low central venous pressure anesthesia were not used. RESULTS: Only 14 (15.5%) patients received blood transfusion (mean transfused blood volume 397 ml; mode 310 ml) and 10 of 14 patients received <310 ml of blood. There was no statistical difference between the patients who underwent major and minor liver resection in frequency of blood transfusion. Blood loss was associated with dense adhesions and difficult liver mobilization and not with liver transection. CONCLUSION: The 'sequential coagulate-cut' RF-assisted liver resection technique is a safe liver transection technique associated with minimal blood loss and it has facilitated tissue-sparing liver resection. 相似文献

The results are presented of 50 intertrochanteric osteotomies after a minimum observation time of 9.3 years. This method of treatment was found to be of lasting benefit in 86 per cent of the patients. the results encourage us to consider osteotomy also in younger patients with osteoarthritis. 相似文献

The design, synthesis and biological activity of a series of novel non-covalent D-Phe-Pro-Arg motif-based thrombin inhibitors incorporating 4,5,6,7-tetrahydrobenzothiazol-2-amine as a novel arginine surrogate are described. Compound 9, the most potent in the series of thrombin inhibitors, exhibited an in vitro K(i) of 128 nM and 342-fold selectivity against trypsin. The binding mode of this novel class of thrombin inhibitors in the enzyme active site, based on the X-ray crystal structure of compound 9 co-crystallized with human alpha-thrombin, is discussed. 相似文献

BACKGROUND: The modern concept of type-related individualized groin hernia surgery imposes a demand for precise and accurate preoperative determination of the type of groin hernia. The aim of this prospective study was to evaluate the accuracy of ultrasonography in classification of groin hernias, according to the criteria of the unified classification system. Unified classification divides groin hernias into nine types (grades): type I (indirect, small), II (indirect, medium), III (indirect, large), IV (direct, small), V (direct, medium), VI (direct, large), VII (combined-pantaloon), VIII (femoral), and O (other). PATIENTS AND METHODS: One hundred and twenty-five adult patients with clinically diagnosed or suspected groin hernias were examined. Ultrasonography of both groins was performed with a 5 to 10-MHz linear-array transducer. Preoperative ultrasonographic findings of type of groin hernia were compared with the intraoperative findings, which were considered the gold standard. RESULTS: Total accuracy of ultrasonography in determination of type of groin hernia was 96% (119 of 124 correct predictions of type of groin hernia compared with surgical explorations). All hernias of types I, IV, V, VII, and VIII were correctly identified with ultrasonography (sensitivity and specificity 100%). In the remaining five cases of the 124 (4%), hernia was incorrectly classified with ultrasonography: type VI (direct, large) was misdiagnosed as type III (indirect, large) in three cases, type III as type VI in one case, and type III as type II (indirect, medium) in one case. The sensitivity and the specificity of ultrasonography in classifying type II were 100 and 99%, respectively, for type III, 85 and 97%, and for type VI, 90 and 99%. CONCLUSION: Ultrasonography of the groin regions could be used with great accuracy for precise classification of groin hernias in adults. Each type of groin hernia, according to the unified classification system that we used for classification, has a characteristic ultrasonographic presentation, which is demonstrated in this study. 相似文献

A commercially available automated device (MagNA Pure LC) was adapted for nucleic acid extraction of urogenital specimen for subsequent PCR detection of Chlamydia trachomatis and Neisseria gonorrhoeae in a clinical laboratory. Results were compared to the standard manual extraction procedure and showed excellent correlation, with even slightly increased sensitivity. 相似文献
