METHODS: A Meta-analysis was performed using databases, including Pubmed, Embase, and the Cochrane library. At least one of the clinical outcomes and/or complications data in each included randomized controlled trials(RCT) was reported. The quality of the RCT was assessed with the Cochrane risk assessments tool.RESULTS: Overall, 25 RCTs including 3781 eyes were included. No statistically significant difference detected between FLACS and CPCS in terms of corrected distant visual acuity(CDVA), uncorrected distant visual acuity(UDVA), and central corneal thickness(CCT) at the longterm follow up, although FLACS showed better CDVA at 1 wk postoperatively, and less increase in CCT at 1 d and 1 wk. FLACS had better postoperative endothelial cell count(ECC) at 1 and 4-6 wk, while there was no significantly difference between FLACS and CPCS at 1 d, 3 and 6 mo [weighted mean difference(WMD): 51.54, 95% confidence interval(CI):-5.46 to 108.54, P=0.08;WMD: 48.52, 95%CI:-17.54 to 114.58, P=0.15;WMD: 12.17, 95%CI:-48.61 to 72.94, P=0.69, respectively]. Postoperative endothelial cell loss(ECL) of the FLACS was significantly lower than that of the CPCS at 1, 4-6 wk, and 3 mo(P=0.02, 0.008, 0.03, respectively). However, there was no significant difference between two groups at 6 mo(WMD:-30.36, 95%CI:-78.84 to 18.12, P=0.22). No significant difference was discovered with respect to the macular edema [odds ratio(OR): 0.93, 95%CI: 0.42 to 2.05, P=0.85], capsular complication excluding posterior capsular tears(OR: 0.79, 95%CI: 0.42 to 1.50, P=0.47) and intraocular pressure change(OR: 0.82, 95%CI: 0.39 to 1.72, P=0.60). However, posterior capsular tears were more common in CPCS group(OR: 0.12, 95%CI: 0.01 to 0.98, P=0.05). The effective phacoemulsification times were significantly lower in the FLACS group compared to the CPCS group(WMD:-0.78, 95%CI:-1.23 to-0.34, P=0.0006).CONCLUSION: No statistically significant difference is discovered between FLACS and CPCS in clinical outcomes at the long-term follow up. However, higher rate of posterior capsular tears is detected in patients receiving CPCS.展开更多

The underlying principle is to enable patients to recover from surgery and leave the hospital sooner by minimizing the stress responses on the body during surgery. Our aim was to compare the outcome of fast-track protocol and conventional methods in colorectal surgery. Method: It was an observational cross-sectional study carried out at the Department of Surgery in different tertiary level hospitals, Dhaka Bangladesh during the period January 2014 to December 2017. Among this population, 50 patients were placed in the fast-track program (Group A) from January 2014 to December 2015 and 50 patients were in the conventional method (Group B), from January 2016 to December 2017. The fast-track patients were selected after receiving ethical approval from the Bangladesh College of Physician & Surgeons. Data analysis was done using the statistical package for social science (SPSS) for windows version 20. Results: The average age of the patients was 45.24 ± 16.65 years (range: 11 - 70 years) in the fast track group (Group A) and 43.24 ± 17.76 years in the conventional method (Group B). The majority were female between two groups, with 56% in group A and 52% in group B. General and surgical complications occurred in 9 (18%) patients and 11 (22%) patients respectively in group A. On the other hand in group B general and surgical complications occurred in 10 (20%) patients and 13 (26%) patients respectively. The average hospital stay was 9.24 ± 5.99 days in group A and the average hospital stay was 10.10 ± 6.04 days in group B. Conclusion: Making the decision to adopt fast-track surgery will challenge current traditional practice for all members of the multidisciplinary team across the whole local health community.展开更多
