Objective To summarize the visual outcome of patients with severe ocular trauma treated with vitreous surgery. Methods Clinical data of 188(191 eyes) with severe ocular trauma treated with vitreous surgery in a period from November 1996 to April 1998 were analysed retrospectively. Results The study included penetrating injury in 56 eyes, foreign bodies in the posterior segment in 70 eyes, blunt injury in 41 eyes , and globe rupture in 24 eyes. Main complications included endophthalmitis in 35 eyes, choroidal bleeding in 20 eyes, retinal detachment in 60 eyes, and vitreous hemorrhage in 97 eyes. Post-opera-tively, out of 188 eyes, except for 3 of patients too young to examine, visual acuity improved in 133(70.7%), including 85(45.2%) with visal acuity 0.02-1.0, 46(24.5%) remained unchanged; and 9(4.8%) had worse vision. Among 34 with no-light-perception, 12 had light-perception or over. Conclusion A majority of severe trauma eyes can be salvaged with considerable visual recovery after adequate and timely vitreous surgery. (Chin J Ocul Fundus Dis,1999,15:4-6)
Objective To assess the safety and effectiveness of laparoscopic hysterectomy (LH) for women with benign gynecological diseases. Methods Such databases as CENTRAL (The Cochrane Library, Issue 5, 2012), MEDLINE, EMbase, CNKI, WanFang Data, VIP and CBM were searched from the date of their establishment to May 2012, meanwhile the relevant gray literature was also retrieved to identify the randomized controlled trials (RCTs) about LH versus abdominal hysterectomy (AH) for benign gynecological diseases. The literature was screened according to the inclusion and exclusion criteria by two reviewers independently, and the methodology quality was evaluated after extracting the data, then RevMan 5.1 software was used for meta-analysis. Results A total of 22 RCTs involving 3 304 patients were included. The results of meta-analysis showed that, compared with AH, LH was shorter in the time of both hospital stay (MD=–2.31, 95%CI –3.03 to –1.60, Plt;0.000 01) and postoperative recovery (MD=−13.86, 95%CI −17.70 to −10.03, Plt;0.000 01), and lower in the incidences of both postoperative fever and other nonspecific infections (OR=0.72, 95%CI 0.54 to 0.95, P=0.02), but it was higher in the incidence rate of intraoperative urinary systematic injuries (OR=2.41, 95%CI 1.21 to 4.82, P=0.012), and longer in the operation time (MD=20.27, 95%CI 3.95 to 36.59, P=0.03). There were no significant differences between the two groups in the incidence of complications such as intraoperative intestinal injuries, vessel injuries, postoperative fistulizaion, postoperative urethral dysfunction, postoperative vaginal infection, etc. (Pgt;0.05). Conclusion This systematic review shows when treating benign gynecological diseases, LH is superior to AH in shortening the time of hospital stay and postoperative recovery, and in decreasing the incidence of operative fever and other nonspecific infections, but it results in a higher incidence of intraoperative urinary systematic injuries and longer operative time. Because there is no result regarding to the postoperative long-term life quality, so it expects to be further proved by more high quality RCTs.
ObjectiveTo study the gastric function of vagus-preserved patients after esophagectomy, and to evaluate the significance of keeping vagus and the value of gastric tube with vagal-sparing esophagectomy. MethodsWe retrospectively analyzed clinical data of 15 patients in West China Hospital between June 2012 and January 2014. They were divided into two groups. There were 8 patients with 6 males and 2 females with average age of 57 years ranging from 44 to 77 years, in a gastric pull-up group with vagal-sparing esophagectomy. There were 7 patients with 6 males and 1 female at average age of 60 years ranging from 50 to 70 years in a gastric tube group with vagal-sparing esophagectomy. We chose 8 patients with 7 males and 1 female at average age of 62 years ranging from 47 to 69 years as a control group with a classical esophagectomy and a gastric pull-up. Then we evaluated the function of the vagal nerves and gastric reservoir after vagal-sparing esophagectomy. ResultsAll 23 surgeries were successfully performed. In subjective symptom, diarrhea was rare in the vagal-sparing esophagectomy patients and statistically more common in patients with a standard esophagectomy. Dumping and early satisfaction situation were similar among 3 groups. The 60 minutes gastric emptying rate was much better in the vagal-sparing group than that in the control group. And the esophageal manometry of the vagal-sparing group was statistically hihger than that in the control group. The gastroscope showed that the incidence of reflux esophagitis in the vagal-sparing group was statistically lower than that of the control group. There was no statistic difference in weight in the vagus-preserved group before and after the surgery while the weight decreased statistically in the control group. ConclusionsFor both esophageal replacement and gastric tube, preserving the vagus can reduce the functional dyspepsia after esophagectomy.
Objective To systematically evaluate the effectiveness and safety of laparoscopic hepatectomy (LH) versus open hepatectomy (OH) for hepatocellular carcinoma (HCC). Methods Databases including PubMed, EMbase, MEDLINE, SCI, CNKI, CBM, WanFang Data and The Cochrane Library (Issue 3, 2012) were searched to collect the randomized controlled trails (RCTs) and non-RCTs about LH versus OH for HCC. The retrieval time was from inception to August 2012. The studies were screened according to the inclusion and exclusion criteria, the data were extracted and the quality was evaluated by 2 reviewers independently. Then the meta-analysis was conducted using RevMan 5.1 software. Results A total of 13 non-RCTs involving 701 patients were included. The results of meta-analysis showed that: Compared with OH, LH had lesser amount of intraoperative bleeding (MD=?144.09, 95%CI ?194.25 to ?93.94, Plt;0.000 01), shorter hospital stay (MD=?5.48, 95%CI ?7.10 to ?3.85, Plt;0.000 01), and lower postoperative complications (OR=0.43, 95%CI 0.27 to 0.66, P=0.000 1). But there were no differences between the 2 groups in operation time (MD=?0.64, 95%CI ?22.95 to 21.68, P=0.96), perioperative death rate, 3-5 year survival rate, and tumor free survival rate. Conclusion LH is superior to OH in treating HCC for it is associated with smaller wound, lesser operative blood loss, shorter hospital stay, and lower postoperative complications. And it is similar as OH in operation time, perioperative death rate and 3-5 year survival rate. So LH is safe and feasible for treating HCC when its indications are strictly controlled. However, for the quantity and quality limitation of the included studies, this conclusion still requires to be further proved by performing large scale and high quality RCTs. It suggests that doctors should choose a best therapy for HCC patients according to an integrative disease assessment.
Objective To systematically review the effectiveness and safety of single-incision laparoscopic cholecystectomy (SILC) versus conventional multiport laparoscopic cholecystectomy (CMLC). Methods We electronically searched PubMed, EMbase, The Cochrane Library (Issue 1, 2013), CBM, CNKI, VIP and WanFang Data for randomized controlled trials (RCTs) on SILC versus CMLC from inception to January 1st, 2013. According to the Cochrane methods, the reviewers screened literature, extracted data, and assessed the methodological quality. Then, meta-analysis was performed using RevMan 5.2 software. Results Finally, 17 RCTs involving 1 233 patients were included. The results of meta-analysis showed that, compared with CMLC, SILC was lower in 24 h postoperative pain score (visual analogue scale, VAS) (SMD= –0.40, 95%CI –0.76 to –0.04, P=0.03), higher in cosmetic results score (SMD=1.56, 95%CI 0.70 to 2.43, P=0.000 4), and longer in operative time (MD=13.11, 95%CI 7.06 to 19.16, Plt;0.000 1). However, no significant difference was found in 6 h postoperative pain scores (VAS), postoperative complications, port-site hernia and hospital stay between the two groups. Conclusion SILC is a safe and effective technique for the treatment of uncomplicated benign gallbladder diseases, and it has certain advantages compared with CMLC, which is recommended in clinical application.
Objective To assess the safety and effect of different intravenous chemotherapic regimens in patients with gastric carcinomas who had received gastrectomy. Method A systematic review of all the relevant randomized controlled trials (RCTs) was performed. RCTs were identified from Medline and Embase (1980-2001.4), Chinese Bio-medicine Database (1990-2001.1). Literature references were checked at the same time. We included randomized andquasi-randomized trials in patients with confirmed gastric carcinomas who had received gastrectomy comparing the effect of intravenous chemotherapy after gastrectomy with that of gastrectomy alone.Results Twenty trials involving 4 171 patients were included. Meta-analysis was done with fixed effects model. Heterogeneity analyses was performed also. The effects of intravenous chemotherapy with 5FU + MCCNU, 5FU + MMC, 5FU + BCNU or FAM after gastrectomy were failed to show have better effects than that of surgery alone. There were eleven trials which detailed the side effects according to the toxicity grade by WHO standard. The side effects halting treatment were haematologic and biochemical toxicity, debilitating nausea and vomiting. There were twenty-two patients died of chemotherapic toxicity. Conclusions Based on the review, there is no enough evidence to show that intravenous chemotherapy after gastrectomy have positive treatment effect on gastric cancer.
Objectives To assess the clinical effectiveness of non-penetrating trabecular surgery versus trabeculectomy for open angle glaucoma. Methods We searched the Cochrane Central Register of Controlled Trials (issue 2, 2007), MEDLINE (1966 to May 2008), EMbase (1980 to May 2008), and CMB-disk (1979 to May 2008). We also hand searched relevant journals and conference proceedings. Data were extracted by two reviewers independently using an extraction form. The Cochrane Collaboration’s RevMan 5.0 software was used for statistical analysis. Results Three RCTs involving 127 participants (144 eyes) with previously untreated open angle glaucoma were included. Meta-analysis showed that compared with non-penetrating trabecular surgery, trabeculectomy increased the proportion of patients with reduced postoperative intraocular pressure (WMD2.78, 95%CI 1.41 to 4.15), improved the operation success rate (RR 0.53, 95%CI 0.37 to 0.77), and reduced the use of postoperative antiglaucoma medication (WMD 0.96, 95%CI 0.84 to 1.08). Non-penetrating trabecular surgery reduced the incidence of postoperative complications (RR 17.00, 95%CI 8.36 to 26.00). Conclusion Since the sample sizes of the included trials are relatively small, and the two procedures are also related to progressive visual field loss and optic disk damage, more well-designed large-scale RCTs are required.
Objective To evaluate the effect of epristeride on gross hematuria secondary to transurethral resection of prostate (TURP). Methods A total of 50 patients with gross hematuria secondary to TURP were divided into two groups: 25 patients were treated with routine treatment plus 5 mg epristeride, twice a day for 3 months, while the other 25 only received routine treatment. Results At the 6-month follow-up visit, gross hematuria recurred in 63% of patients in the control group, but in only 30% of patients in the epristeride group. The difference was statistically significant (Plt;0.05). Moreover, the grade of gross hematuria was significantly lower in the epristeride group (Plt;0.05). Conclusion Epristeride appears to be effective in treating gross hematuria secondary to TURP.
