RESUMO
Gastroscopy is a widely used examination for the diagnosis and treatment of upper gastrointestinal diseases in most countries and regions. High quality gastroscopy is much important for the diagnosis, treatment and prevention of gastrointestinal diseases. Gastroscopy is an operation highly dependent on the skills of gastroscopy physician, and the difference in the quality of operation may have an important impact on the quality of gastroscopy. It is an urgent problem for gastroscopy clinicians to improve the quality of gastroscopy. The improvement of gastroscopy quality not only can reduce the morbidity and mortality of upper gastrointestinal diseases, but also can improve the overall medical quality. This article reviewed the progress of research on the quality indicators of diagnostic gastroscopy.
RESUMO
<p><b>OBJECTIVE</b>To explore whether bariatric surgery can decrease the incidence of obesity-related tumors in obesity patients.</p><p><b>METHODS</b>Relevant studies comparing the incidence of obesity-related tumors in obesity patients between bariatric surgery and non- bariatric surgery were identified by search of PubMed, Medline, EBSCO, High Wire Press, OVID, EMbase, China hownet (CNKI) and Wanfang databases since the self-built database. In strict accordance with the standard after the screening, literature quality and extracted data were evaluated. Review manager 5.2 software was used to perform meta-analysis and sensitivity analysis. Inverted funnel chart was used to investigate the publication bias.</p><p><b>RESULTS</b>Five articles including 108 954 patients were enrolled in the analysis. Among them, 26 218 cases were bariatric surgery group, and 82 736 cases of non-surgical weight loss were the control group. Meta analysis showed that bariatric surgery could obviously decrease the incidence of postoperative obesity-related tumor(RR=0.60, 95% CI:0.45-0.80, P=0.0005). Subgroup analysis showed that cancer risk difference of obesity-related tumor in male patients was not significant between two group, while the postoperative incidence of obesity-related tumor of female patients in bariatric surgery group was significantly lower compared to those female patients in control group(RR=0.68, 95% CI:0.61-0.77, P<0.01). During follow-up of 1 to 10 years, the incidence of obesity-related tumor in bariatric surgery group was significantly lower than that in control group(P<0.05). When follow-up was more than 10 years, the incidence of obesity-related tumors was similar between two groups(P=0.70).</p><p><b>CONCLUSION</b>Bariatric surgery can decrease the overall risk of obesity-related cancer, especially for female patients, but with the prolongation of time, such effect of bariatric surgery is not obvious.</p>
RESUMO
<p><b>OBJECTIVE</b>To investigate the impact of intestinal spasmolytic on colon polyps and adenoma detection rate during colonoscopy.</p><p><b>METHODS</b>Literatures related to the effect of intestinal spasmolytic on colon polyp or adenoma detection rate were retrieved from PubMed, Medline, EBSCO, High Wire Press, OVID, EMBASE, and the China National Knowledge Articles, etc. published before July 2014. Unified data were extracted by two researchers independently and organized using Jadad scale to evaluate the quality of the enrolled studies through Review manager 5.2 Meta-analysis software.</p><p><b>RESULTS</b>Six articles were enrolled with total 47,509 cases, including 16,867 cases in the scopolamine group and 30,642 cases in the placebo group. Meta analysis showed spasmolytic could increase the detective rate of polyps (OR=1.24, 95% CI:1.19-1.30), adenoma (OR=1.25, 95% CI:1.19-1.30) and high-risk adenoma (OR=1.22, 95% CI:1.16-1.29).</p><p><b>CONCLUSION</b>Using colonoscopy spasmolytic scopolamine can increase the detection rate of colonic polyp and adenoma.</p>
