1. Meta-analysis of single-incision versus three-port laparoscopic appendectomy comparing operation time and postoperative pain.
Across 21 RCTs (n=2454), single-incision appendectomy had a nonsignificant 3.8-minute longer operative time versus three-port, a trend toward reduced time differences in recent years, similar pain scores at 12 and 24 hours, and comparable complications and conversion rates. Cosmetic satisfaction was higher with SILA, though 7% required an additional trocar.
Impact: This high-quality meta-analysis of RCTs integrates cosmetic satisfaction with standard surgical outcomes, supporting SILA as a patient-centered option without sacrificing safety.
Clinical Implications: For patients prioritizing cosmetic outcomes, SILA can be offered with counseling about slightly longer operative time and a small chance of needing an extra port, while expecting similar pain and complication profiles to CLA.
Key Findings
- SILA averaged 3.80 minutes longer than CLA (MD 3.80; 95% CI −0.25 to 7.85; p=0.07).
- Meta-regression showed operative time differences decreased in more recent studies (p=0.003).
- CLA required fewer additional analgesics (SMD 0.24; 95% CI 0.10 to 0.38; p<0.01), but pain scores at 12 and 24 hours were not different.
- Postoperative complications and open conversion rates were similar between groups.
- Cosmetic satisfaction favored SILA; 7% of SILA cases required an additional trocar.
Methodological Strengths
- Systematic inclusion of 21 RCTs with exclusion of high risk-of-bias trials
- Meta-regression explored temporal trends, improving interpretability
Limitations
- Heterogeneity in analgesic protocols and outcome definitions across trials
- Limited long-term outcomes; cosmetic satisfaction measures may vary by study
Future Directions: Conduct contemporary RCTs with standardized analgesia and core outcome sets including validated cosmetic and patient-reported outcomes; evaluate hernia and port-site complications over longer follow-up.
BACKGROUND: Unresolved debates persist regarding operative time and postoperative pain when comparing single-incision laparoscopic appendectomy (SILA) with three-port conventional laparoscopic appendectomy (CLA) for acute appendicitis. To address these issues, we conducted a systematic review and meta-analysis of randomized clinical trials (RCTs) comparing the clinical outcomes of SILA and CLA. METHODS: An electronic search was performed using PubMed, Embase, and the Cochrane Central Register of Controlled Trials through January 2025. The primary outcomes were operative time and postoperative pain, while secondary outcomes included the incidence of postoperative complications, additional trocar requirements, open conversion rate, and cosmetic satisfaction. A meta-regression was conducted to assess the relationship between surgical outcomes and the era in which the surgery was performed. RESULTS: After excluding four RCTs because of a high risk of bias in the randomization process, a total of 21 RCTs encompassing 2454 patients were included. The pooled analysis showed that SILA required an average of 3.80 minutes longer than CLA (mean difference [MD] = 3.80 minutes, 95% confidence interval [CI]:-0.25 to 7.85; p = 0.07). However, meta-regression of studies arranged by initiation year revealed a significant trend toward a decreased MD with more recent surgeries (p = 0.003). Although the CLA group required fewer additional analgesics (standardized mean difference [SMD] = 0.24, 95% CI: 0.10 to 0.38, p < 0.01), no significant differences were found in pain scores at 12 hours (MD = -0.04, 95% CI:-0.72 to 0.63, p = 0.91) or 24 hours (MD = 0.08, 95% CI:-0.30 to 0.46, p = 0.67). Furthermore, while postoperative complications and open conversion rates were similar between groups, the SILA group reported higher cosmetic satisfaction. Additional trocars were inserted in 60 of 932 SILA cases (weighted proportion = 0.07, 95% CI: 0.05 to 0.10). CONCLUSION: Given the diminishing difference in operative time and manageable postoperative pain compared with CLA, SILA may be considered a viable alternative for the treatment of acute appendicitis, particularly in selected patients for whom cosmetic outcomes are a priority.
2. Impact of Scar on Quality of Life in Well-Differentiated Thyroid Carcinoma: A Systematic Review.
Across 9 studies (14 cohorts; n=3658), scar-related QoL items ranked among the least important concerns in thyroidectomy survivors, often last. Despite biases and heterogeneity, findings were consistent across regions. Remote access thyroidectomy should be justified by benefits beyond cosmetic scar concealment.
Impact: Challenges a prevailing assumption that scar concerns dominate QoL after thyroidectomy, reframing indications for cosmetic-driven remote access approaches.
Clinical Implications: Counsel patients that scar-related QoL burden is generally low; remote access techniques should offer demonstrable functional, oncologic, or recovery advantages to warrant their use.
Key Findings
- In 12/14 cohorts, scar-related QoL items ranked below sixth among domains assessed.
- In 7 cohorts, scar-related items ranked the lowest among all QoL items.
- Thyca-QoL was the most frequently used instrument; common limitations included selection and recall biases.
- Consistency across geographically and culturally diverse populations.
Methodological Strengths
- Comprehensive multi-database search with inclusion of validated QoL instruments
- Large combined sample size (n=3658) and formal study quality assessment (JBI)
Limitations
- Predominantly cross-sectional designs limit causal inference
- Heterogeneity of instruments and timing; potential selection and recall biases
Future Directions: Prospective, longitudinal studies comparing open versus remote access techniques with standardized, validated QoL and cost-effectiveness outcomes.
OBJECTIVE: Remote access techniques in thyroid surgery have been developed to improve cosmetic outcomes, based on the presumed impact of surgical scars on patients' quality of life (QoL). This systematic review aimed to evaluate the impact of surgical scars on the overall QoL of patients who have undergone thyroidectomy for low-risk thyroid carcinoma. The review focuses on the rank of scar-related QoL issues relative to other aspects assessed by validated QoL instruments. DATA SOURCES: MEDLINE, EMBASE, CENTRAL, LILACS, Google Scholar (no language or time restrictions). REVIEW METHODS: A systematic review was conducted for original articles using validated QoL instruments with scar-related domains in thyroid cancer patients who had undergone OT. Study quality was assessed using the JBI critical appraisal tool for cross-sectional studies. Data were analyzed from 14 patient groups across 9 studies, representing 3658 patients. RESULTS: In 12 of 14 samples, scar-related issues ranked lower than sixth place in QoL assessments, with 7 samples placing scar-related items at the lowest position. The Thyca-Qol questionnaire was the most commonly used tool, though most studies had limitations, including selection and recall biases. However, across geographically and culturally diverse populations, scar-related concerns consistently ranked lower in importance compared to other QoL factors. CONCLUSIONS: The impact of surgical scars on QoL in thyroid cancer survivors is low, with scar-related items ranking among the least significant issues. Remote access techniques designed primarily for cosmetic outcomes should demonstrate additional benefits to justify their use.
3. Detection of nontoxic BoNT/A levels in post-facial Botox injection breastmilk.
In a five-participant analytical case series, ELISA detected very low BoNT/A concentrations in breastmilk after facial injections, peaking around day 4 (167 pg/mL) and again near 2 months (133 pg/mL), with detectability up to >1 year. Orthogonal methods (LC-MS, WB, Raman) did not confirm BoNT/A, and levels are likely safe for infants.
Impact: Provides rare human data on BoNT/A in breastmilk after cosmetic use, directly informing risk communication for breastfeeding patients considering Botox.
Clinical Implications: Breastfeeding patients receiving facial Botox may be reassured that detected BoNT/A levels are extremely low; shared decision-making can address timing of injections relative to feeding and individual risk tolerance.
Key Findings
- ELISA detected BoNT/A in breastmilk ranging 34.4–167 pg/mL; peak at 4 days (167 pg/mL) and around 2 months (132.725 pg/mL) post-injection.
- BoNT/A remained detectable in some samples more than a year after injection.
- LC-MS, Western blotting, and confocal micro-Raman spectroscopy did not clearly detect BoNT/A; WB and Raman show promise for future development.
- Authors conclude the measured concentrations are likely safe for infants.
Methodological Strengths
- Multiple orthogonal analytical techniques applied to human breastmilk samples
- Serial sampling across a wide post-injection timeline (hours to >1 year)
Limitations
- Very small sample size (n=5) limits generalizability
- Lack of infant clinical outcomes and inconsistent detection across methods
Future Directions: Larger prospective studies with standardized assays, pharmacokinetic modeling, and linkage to infant outcomes to establish exposure thresholds and clinical guidance.
The use of cosmetic Botox (BoNT/A) has become increasingly prevalent among women, even during the post-pregnancy breastfeeding period. However, there is currently a limited understanding of the extent Botox enters breastmilk and its potential effect on the breastfeeding infant. In this study, breastmilk samples were acquired from five women aged between 28 and 45. Three sample sets ranged from 1 h to 1 year after facial Botox treatments (64 U), whereas the remaining two were from women who never received Botox. BoNT/A concentrations in samples were detected using standard Enzyme-Linked Immunosorbent Assay (ELISA), unreduced and reduced Western Blotting, confocal micro-Raman Spectroscopy, and Mass Spectrometry (LC-MS). From ELISA, the greatest breastmilk BoNT/A concentration was found from woman 1, 4 days after Botox injection (167 pg/mL). Levels were highest overall in the first week (82.45-167 pg/mL) and around 2 months (132.725 pg/mL) after injection. No clear indication of BoNT/A was detected in Mass Spectrometry (LC-MS), Western Blotting and confocal micro-Raman Spectroscopy, but Western blot and confocal micro-Raman Spectroscopy show promise of development into future means of detection. From our study, the amount of BoNT/A in breastmilk peaks around 4 days (167 pg/mL) and at 2 months (132.725 pg/mL) after facial injection. Even over a year after injection, BoNT/A can be detected. However, all quantities of BoNT/A detected (between 34.4 pg/mL and 167 pg/mL) are likely to be safe for infants.
