RESUMO
The purpose of the current study was to compare outcomes of diclofenac versus corticosteroids following strabismus surgery. A systematic review and meta-analysis were performed in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. An electronic search was performed to include comparative studies of diclofenac versus corticosteroids following strabismus surgery. The analysis was based on fixed and random effect models. Primary outcomes included discomfort, chemosis, inflammation, conjunctival gap, intraocular pressure, and conjunctival injection. Secondary outcomes were conjunctival congestion, discharge, and drop intolerance. Eight studies with a sample of 469 eyes were included. At weeks 1 and 4 postoperatively, there were no statistically significant differences between the diclofenac and corticosteroid groups, except for conjunctival injection at week 1 (mean difference [MD] = -0.21, P = .04) favoring diclofenac. Interestingly, all primary outcomes significantly favored diclofenac at week 2: discomfort (MD = -0.34, P = .03), conjunctival chemosis (MD = -0.16, P = .04), conjunctival inflammation (MD = -0.16, P = .02), conjunctival gap (MD = -0.17, P = .002), intraocular pressure (MD = -2.53, P < .00001), and conjunctival injection (MD = -0.30, P = .03). Moreover, conjunctival congestion was significantly improved for dexamethasone, whereas discharge and drop intolerance was not statistically different. Diclofenac is comparable to various corticosteroids when used following strabismus surgery. However, it is important to note that diclofenac yielded significant improvements in discomfort, conjunctival chemosis, inflammation, conjunctival gap, intraocular pressure, and conjunctival injection, mainly at 2 weeks postoperatively.

RESUMO
This study aimed to compare the outcomes of coblation versus bipolar diathermy in pediatric patients undergoing tonsillectomy. A systematic review and meta-analysis were performed per the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Guidelines. An electronic search of information was conducted to identify all Randomized Controlled Trials (RCTs) comparing the outcomes of coblation versus bipolar in pediatric patients undergoing tonsillectomy. Primary outcome measures were intraoperative bleeding, reactionary hemorrhage, delayed hemorrhage, and post-operative pain. Secondary outcome measures included a return to a normal diet, effects on the tonsillar bed, operation time, and administration of analgesia. Fixed and random-effects models were used for the analysis. Seven studies enrolling 1328 patients were identified. There was a significant difference between coblation and bipolar groups in terms of delayed hemorrhage (Odds Ratio [OR] = 0.27, P = 0.005) and post-operative pain (standardized mean difference [MD] = -2.13, P = 0.0007). Intraoperative bleeding (MD = -43.26, P = 0.11) and reactionary hemorrhage did not show any significant difference. The coblation group improved analgesia administration, diet and tonsillar tissue recovery, and thermal damage for secondary outcomes. No significant difference was reported in terms of operation time. In conclusion, coblation is comparable to a bipolar technique for pediatric patients undergoing tonsillectomy. It improves postoperative pain and delayed hemorrhage and does not worsen intraoperative bleeding and reactionary hemorrhage.
RESUMO
Purpose: To compare outcomes of diclofenac versus dexamethasone in patients after strabismus surgery. Methods: A systematic review and meta-analysis were performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A search was conducted on MEDLINE, EMBASE, EMCARE, CINAHL, and the Cochrane Central Register of Controlled Trials (CENTRAL). All randomized controlled trials (RCTs) comparing the outcomes of diclofenac versus dexamethasone poststrabismus surgery were included. An extraction spreadsheet for data collection and Review Manager 5.3 were used for data analysis based on the fixed and random effects models. Discomfort, inflammation, chemosis, conjunctival gap, and intraocular pressure (IOP) were primary outcome measures. Secondary outcomes included conjunctival congestion and injection, discharge, and drop intolerance. Fixed and random effects models were used for the analysis. Results: Five RCTs enrolling 248 subjects were enrolled. At week 2 postoperatively, there was a significant difference favoring diclofenac over dexamethasone in terms of discomfort (mean difference [MD] = -0.37, P = 0.02), conjunctival inflammation (MD = -0.16, P = 0.02), conjunctival chemosis (MD = -0.16, P = 0.04), and postoperative conjunctival gap (MD = -0.17, P = 0.002). In terms of IOP, there were no significant differences. However, no statistically significant differences were noted at weeks 1 and 4 postoperatively. For secondary outcomes, dexamethasone had significantly improved conjunctival congestion; however, diclofenac had significantly less injection at the site of muscle attachments at week 2. No significant difference was noted in terms of discharge and drop intolerance. Conclusion: Diclofenac is comparable to dexamethasone when used following strabismus surgery. However, a significant difference favoring diclofenac in terms of discomfort, inflammation, conjunctival chemosis, and conjunctival gap was only noted at 2 weeks postoperatively. The authors suggest conducting further studies to support the effectiveness of diclofenac as an alternative to corticosteroids following strabismus surgery.
