Objective To compare endoscopic sinius surgery plus middle meatus fenestration with endoscopic sinius surgery plus middle and inferior meatus fenestration for fungus ball maxillary sinusitis. Methods Applying a prospective randomized controlled trial, 80 patients with fungal ball maxillary sinusitis from January, 2010 to March, 2011 were collected and then divided into two groups, including experiment (40 cases) and control groups (40 cases). The trial group received endoscopic sinius surgery plus middle and inferior meatus fenestration, which the control group received endoscopic sinius surgery plus middle meatus fenestration. Then a follow-up was conducted from the end of surgery to February 28th, 2013. All patients took subjective and objective assessment before and after the surgery, including VAS, SNOT-20, Lund-Mackay CT system scores and Lund-Kennedy endoscopic mucosal score. Results with the trial group was superior to the control group in VAS score, SNOT rating and Lund-Kennedy mucosa score 6 months, 1 year, and 2 years after surgery (Plt;0.01). Lund-Mackay CT score of the control group was significantly higher than the trial group after 1 year of surgery (Plt;0.01). According to the Haikou standard to assess the efficacy of surgery, we found that the total effectiveness rate of the trial group (100.0%; recovery: 36 cases; improved: 4 cases) was higher than that of the control group (87.5%; recovery: 28 cases; improved: 4 cases), with a significant difference (P=0.021). Conclusion Endoscopic sinius surgery plus middle and inferior meatus fenestration with a lower reoccurrence rate is superior to endoscopic sinius surgery plus middle meatus fenestration for fungus ball maxillary sinusitis in clinical efficacy.
Objective To systematically review the effectiveness of endoscopic dacryocystorhinostomy (En-DCR) with versus without Mitomycin C (MMC) for nasolacrimal obstruction. Methods Databases such as PubMed, EMbase, CENTRAL (Issue 12, 2012), VIP, WanFang Data, CBM and CNKI were electronically searched to collect the randomized controlled trials (RCTs) which investigated the comparison between En-DCR with and without MMC for nasolacrimal obstruction. The searched data was updated to December 31st, 2012. According to the inclusion and exclusion criteria, literature was screened, data were extracted, and the methodological quality of the included studies was also assessed. Then, meta-analysis was performed using RevMan 5.2.0 software and the quality of evidences was graded using GRADEpro 3.6 software. Results A total of 9 RCTs were included in the meta-analysis. The results of meta-analysis showed that, the recovery rate in the MMC group was significantly elevated (RR=1.13, 95%CI 1.04 to 1.22, P=0.003), the area of ostium in the MMC group was bigger at 1, 6 and 12 months than in the control group, postoperatively (MD=6.68 mm2, 95% 5.43 to 7.94, Plt;0.000 01; MD=11.61 mm2, 95%CI 4.67 to 18.55, P=0.001; MD=15.65 mm2, 95%CI 2.95 to 28.34, P=0.02), respectively, but the area of ostium in the MMC group at the third month was bigger than that in the control group (MD=8.20 mm2, 95%CI –6.67 to 23.08, P=0.28). The operative time was significantly prolonged in the MMC group (MD=10.1 min, 95%CI 8.00 to 12.20, Plt;0.000 01). Conclusion En-DCR combined with MMC could improve the recovery rate and prevent the over shrinkage of ostium area effectively due to nasolacrimal obstruction.
Objective To compare proton pump inhibitors (PPI) and H2 receptor antagonists (H2RA) for both the prevention of bleeding and the healing of ulcer after endoscopic submucosal dissection (ESD), so as to provide best evidence for treating ESD-induced ulcer in clinic. Methods Databases including PubMed, CENTRAL, EMbase, ISI Web of Knowledge, VIP, CNKI, CBM and WanFang Data were searched from the date of their establishment to October 26, 2012 to collect the randomized controlled trials (RCTs) about comparison of PPI and H2RA on the prevention of bleeding and the healing of ulcer after ESD. Meanwhile the references of the included studies were also retrieved manually. According to the inclusion and exclusion criteria, literature selection, data extraction and quality assessment were performed by four reviewers independently, and meta-analysis was performed using RevMan 5.1 software. Results A total of 6 studies involving 616 patients were included finally. The results of meta-analysis showed that: for the prevention of ulcer bleeding after ESD, PPI preceded H2RA apparently (OR=0.51, 95%CI 0.29 to 0.89, P=0.02), especially when the treatment course was 8-week (OR=0.43, 95%CI 0.22 to 0.82, P=0.01); but among the merged, 8-week and 4-week groups, there were no significant differences between PPI and H2RA in the healing of ESD-induced ulcer (OR=0.85, 95%CI 0.39 to 1.86, P=0.69; OR=1.33, 95%CI 0.28 to 6.27, P=0.72; OR=0.75, 95%CI 0.31 to 1.79, P=0.52). Conclusion PPI is superior to H2RA for the prevention of ulcer bleeding induced by ESD, but there is no significant difference between them in the healing of ulcer, so PPI is recommended to prevent ESD-induced ulcer bleeding in clinic. Due to the limitation of quantity and quality of the included studies, the safety of PPI has to be further proved by conducting more high quality, large scale and multicenter RCTs.
Objective To evaluate the clinical effectiveness of endoscopic third ventriculostomy (ETV) and ventriculal peritoneum shunt (VPS) for hydrocephalus. Methods A fully recursive literature search was conducted in PubMed (1996 to June, 2011), EMBASE (1996 to June, 2011), Cochrane Central Register of Controlled Trials (Issue 3, 2011), CBM (1996 to June, 2011), CNKI and Wanfang Database (1996 to June, 2011) in any language. The randomized or non-randomized controlled trials of hydrocephalus treated by endoscopic third ventriculostomy and ventriculal peritoneum shunt were considered for inclusion. The analyzed outcome variables were overall complications and the survival rate of all time points. Data related to clinical outcomes were extracted by two reviewers independently. Statistical analyses were carried out by using RevMan 5.0 software. Results Nine published reports of eligible studies involving 1 187 participants met the inclusion criteria. Compared with VPS, ETV had no significant differences in short-term (1 or 2 years) survival rate (RR=1.02, 95%CI 0.90 to 1.16, P=0.74; RR=1.14, 95%CI 1.00 to 1.30, P=0.06), but there were significant differences between the two groups in overall complication rate (RR=0.70, 95%CI 0.57 to 0.89, P=0.001), postoperative 3-year survival rate (RR=1.23, 95%CI 1.07 to 1.41, P=0.004), and postoperative 5-year survival rate (RR=1.14, 95%CI 1.29 to 1.66, P=0.05). So the outcomes indicated ETV was superior in controlling the overall complication rate and prolonging the long-term survival rate. Conclusion Current evidence suggests that endoscopic third ventriculostomy is superior to ventriculal peritoneum shunt in reducing the overall complications and prolonging the long-term survival rate, but there is no significant difference in short-term survival rate between the two methods. The effectiveness of the two operational methods for hydrocephalus caused by all specific reasons still has to be further proved by more high-quality, multi-centered and double-blind RCTs.
