The Impact of Platysma Closure on Post-Thyroidectomy Outcomes: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Aim: This systematic review and meta-analysis of randomized controlled trials (RCTs) compare the impact of platysma muscle layer closure technique among patients undergoing thyroidectomy in terms of postoperative outcomes, specifically pain. Methods: Five electronic databases (PubMed, Scopus, Web of Science, Google Scholar, and Cochrane Central Register of Controlled Trials) were searched from inception until July 22, 2023. The Cochrane risk of bias tool 2 was employed for risk of bias (ROB) assessment. Data were pooled as mean difference (MD), standardized MD (SMD), or risk ratio (RR) based on data type (continuous or dichotomous) using RevMan software. Results: This meta-analysis included four RCTs with a total of 426 patients. Three RCTs had a low risk of bias, while one had some concern regarding bias. The overall MD of the postoperative pain score favored the non-closure group over the closure group (MD = 0.63; 95% CI: [0.09, 1.18]; P = 0.02). However, no significant differences were observed between the two groups in terms of patient scar assessment scale (MD= -0.61; 95% CI: [-3.39, 2.17]; P = 0.67), observer scar assessment scale (SMD = 0.26; 95% CI: [-0.30, 0.81]; P = 0.37), length of the scar (MD = 0.27; 95% CI: [-0.12, 0.67]; P = 0.17), wound infection (RR = 0.63; 95% CI: [0.13, 3.16]; P = 0.57), and seroma or hematoma (RR = 3.00; 95% CI: [0.49, 18.55]; P = 0.24). Conclusion: Our findings suggest that the platysma muscle layer closure during thyroidectomy might lead to increased postoperative pain but does not significantly impact scar outcomes or postoperative complications.

Efficacy of LigaSure Versus Harmonic Devices in Laparoscopic Sleeve Gastrectomy: A Systematic Review and Meta-Analysis.

Our goal is to conduct a thorough systematic review and meta-analysis of comparative studies to evaluate the efficacy of LigaSure (Valleylab, Boulder, CO) compared with Harmonic (Ethicon Endo-Surgery, Inc., Cincinnati, OH) devices in patients undergoing laparoscopic sleeve gastrectomy (LSG). Our search strategy, from inception until March 1, 2024, involved multiple databases, including the Cochrane Controlled Register of Trials (CENTRAL), Web of Science (WOS), PubMed, Scopus, and Google Scholar. We evaluated randomized clinical trials using the Cochrane Risk of Bias tool for randomized trials (RoB-2) tool and non-randomized studies using the Risk of Bias In Non-randomized Studies for Interventions (ROBINS-I) tool. The primary outcomes assessed were operative time, mean length of hospital stay, and the rates of intraoperative complications such as bleeding, organ injury, leakage, and hematoma formation. Additionally, we collected data on postoperative complications, including bleeding, abscess formation, leakage, fever (>38°C), and reoperation rates. Data were analyzed using random-effects models and reported as mean difference (MD) or risk ratio (RR) with a 95% confidence interval (CI) using Review Manager software (RevMan, version 5.4 for Windows, The Cochrane Collaboration, 2020). Four studies, comprising two randomized clinical trials (RCTs) and two retrospective cohort studies, involving a total of 692 patients, were included in the analysis. Both the operative time and length of hospital stay did not significantly differ between the LigaSure and Harmonic groups (p>0.05). The pooled analysis also revealed no significant difference between the LigaSure and Harmonic groups in terms of intraoperative and postoperative complications (p>0.05). In conclusion, our systematic review and meta-analysis found no significant statistical or clinical differences between LigaSure and Harmonic devices in terms of operative outcomes and complication rates in patients undergoing LSG.

Efficacy and Safety of Preoperative Melatonin for Women Undergoing Cesarean Section: A Systematic Review and Meta-Analysis of Randomized Placebo-Controlled Trials.

Background: Cesarean section (CS) has been linked to a number of negative effects, such as pain, anxiety, and sleeping problems. The aim of this systematic review and meta-analysis was to investigate the safety and efficacy of preoperative melatonin on postoperative outcomes in pregnant women who were scheduled for elective CS. Methods: We systemically searched 4 electronic databases (PubMed, Scopus, Web of Science, and Cochrane Library) from inception until 10 March 2023. We included randomized controlled trials (RCTs) comparing melatonin and placebo for postoperative outcomes in CS patients. For risk of bias assessment, we used the Cochrane Risk of Bias 2 tool. Continuous variables were pooled as mean difference (MD), and categorical variables were pooled as a risk ratio (RR) with a 95% confidence interval (CI). Results: We included 7 studies with a total of 754 pregnant women scheduled for CS. The melatonin group had a lower pain score (MD = -1.23, 95% CI [-1.94, -0.51], p < 0.001) and longer time to first analgesic request (MD = 60.41 min, 95% CI [45.47, 75.36], p < 0.001) than the placebo group. No difference was found regarding hemoglobin levels, heart rate, mean arterial pressure, total blood loss, or adverse events. Conclusions: Preoperative melatonin may reduce postoperative pain in CS patients without side effects. This research offers a safe and affordable pain management method for this population, which has clinical consequences. Further research is needed to validate these findings and determine the best melatonin dosage and timing.

Efficacy of Harmonic Scalpel Versus Bipolar Diathermy in Hemorrhoidectomy: A Systematic Review and Meta-Analysis of Nine Randomized Controlled Trials.

Hemorrhoidectomy is one of the most common surgical interventions to remove the third and fourth degrees of prolapse hemorrhoid. We carried out this systematic review and meta-analysis of the randomized controlled trials (RCTs) to comprehensively evaluate the efficacy of harmonic scalpel (HS) versus bipolar diathermy (BD) methods in terms of decreasing intraoperative and postoperative morbidities among patients undergoing hemorrhoidectomy. Suitable citations were found utilizing digital medical sources, including the CENTRAL, Web of Science, PubMed, Scopus, and Google Scholar, from inception until December 2022. Only RCTs that matched the inclusion requirements were selected. We used the updated Cochrane risk of bias (ROB) tool (version 2) to assess the quality of the involved citations. The Review Manager (version 5.4 for Windows) was used to perform the pooled analysis. Data were pooled and reported as mean difference (MD) or risk ratio (RR) with a 95% confidence interval (CI) in random-effects models. Overall, there was no significant difference between HS and BD in terms of decreasing intraoperative morbidities like operative time, intraoperative blood loss, mean duration of hospital stay, and mean duration of first bowel movement (P>0.05). Similarly, the rate of postoperative complications like pain, bleeding, urinary retention, anal stenosis, flatus incontinence, and wound edema; was similar in both groups with no significant difference (P>0.05). In conclusion, our pooled analysis revealed there was no substantial difference between HS and BD in terms of intraoperative and postoperative endpoints. Additional RCTs with larger sample sizes are needed to consolidate the power and quality of the presented evidence.
