Introduction: Minimally invasive surgery (MIS) has become standard of care in many high-income countries, but its adoption in low- and middle-income countries (LICs/MICs) has been impeded by resource- and training-related barriers. We hypothesized that trainees in MICs perform MIS procedures less often, and that as procedure complexity increases, the rate of MIS decreases.

Methods: A 22-question survey, distributed to representative leaders across Latin America, collected country-specific graduating trainee case requirements and volumes for four index procedures (cholecystectomy, appendectomy, inguinal hernia repair, colectomy) using MIS or open surgery (OS). USA data was obtained from the Accreditation Council for Graduate Medical Education. Kruskal-Wallis and Mann-Whitney U tests were performed to determine whether the rate of MIS differed across all countries, procedure complexity classes, and high income countries (HICs)/MICs.

Results: Seven experts (70% response rate) completed the survey, representing: Brazil, Chile, Ecuador, Guatemala, Mexico, Panama, and Paraguay. The percentage of MIS completed by trainees varied with mean and interquartile ranges as follows: cholecystectomy (60% ± 54%), appendectomy (41% ± 69%), inguinal hernia repair (19% ± 23%), colectomy (16% ± 29%). There was a significant difference in mean MIS experience across the eight countries (H = 17.6, p = 0.014) and between most complex and least complex procedures (p = 0.039). No difference was found between MICs and HICs (p = 0.786).

Conclusions: We found a significant difference of general surgery trainee exposure to MIS versus OS across the Americas, but the difference was not significantly associated with World Bank Income Groups. Different trainee experiences with MIS and OS may highlight an opportunity for international and bidirectional collaboration.

Introduction: Fibrinolytic agents (FA) activate the fibrinolytic system, converting plasminogen into plasmin to break down fibrin. Their use for irrigation of abdominal abscesses is debated, and this meta-analysis evaluates their efficacy.

Methods: We searched PubMed, Embase, and Cochrane Central for randomized controlled trials (RCTs) comparing FA and saline in percutaneous drainage of abdominal abscesses. Outcomes included length of hospitalization, duration of drainage, and drainage volume. We pooled mean differences (MD) and 95% confidence intervals (CI) using a random-effects model. We also performed a trial sequential analysis (TSA).

Results: We included six RCTs encompassing 299 patients. In the overall analysis, FA increased drainage volume (MD 104.25 mL; 95% CI 35.72-172.77 mL; p = 0.003; I² = 0%). In children, saline reduced hospitalization duration (MD -1.26 days; 95% CI -1.98 to -0.55 days; p = 0.0006; I² = 0%), whereas FA increased drainage volume (MD 84.66 mL; 95% CI 5.77-153.54 mL; p = 0.04; I² = 0%). In adults, FA significantly reduced hospitalization duration (MD -11.12 days; 95% CI -15.16 to -7.08 days; p < 0.00001; I² = 0%) and duration of drainage (MD -6.53 days; 95% CI -9.25 to -3.81 days; p < 0.00001; I² = 0%) while increasing drainage volume (MD 164.47 mL; 95% CI 26.16-302.78 mL; p = 0.02; I² = 0%). On TSA, the required information size was achieved only for the adult subgroup's hospitalization and drainage duration.

Conclusion: In adults, FA reduce hospitalization and drainage duration and increase drainage volume. In children, saline seems more effective in reducing hospitalization duration, while FA increase drainage volume. These findings underscore the need for age-specific treatments and further research, especially in the pediatric population.

Background: Comprehensive studies on priority areas for improving geriatric surgery outcomes, inclusive of geriatric-pertinent data, are limited.

Methods: The ACS NSQIP geriatric database (2014-2018) was used to abstract older adults (≥65 years) undergoing inpatient general surgery procedures. Thirty-day complication, functional decline, and mortality rates were analyzed, with a focus on two geriatric-pertinent complications: delirium and new/worsening pressure ulcers.

Results: There were 9062 patients; 41.9% were ≥75 years. Mean age was 73.9 years. The majority of patients were female (54.0%), White (77.7%), and had independent functional status before surgery (94.0%). Overall 30-day complication, functional decline, and mortality rates were 33.6%, 34.5%, and 3.5%, respectively; failure to the rescue rate was 9.7%. Including geriatric-pertinent complications increased the overall complication rate by 20.4%. Delirium emerged as the leading complication (11.9%), followed by bleeding (11.1%), and wound-related complications (10.1%); these three accounted for 53.7% of complications. Delirium and pressure ulcers were associated with a >50% rate of postoperative functional decline (52.0% and 71.4%, respectively); pressure ulcers were also notable for a 25.5% failure to the rescue rate. Both were also among complications most likely to occur following the 3 most common procedures (colorectal surgery, pancreatic resections, and exploratory laparotomy), which overall accounted for approximately 79.6% of complications, 73.4% of patients experiencing functional decline, and 82.3% of mortality.

Conclusions: Delirium is the leading complication among older adults undergoing inpatient surgery. Overall, a small number of complications and procedure groups account for most surgical morbidity and mortality among older adults and thus constitute priority areas for outcomes improvement.

Background: Global disparities in valvular surgery services exist. Cost-effectiveness analysis (CEA) and cost-utility analysis can be used to guide national investment decisions. This scoping review aims to synthesize economic evaluations for valvular surgery by income settings and provide recommendations.

Methods: A systematic literature review identified primary CEAs or CUAs in English comparing surgical management strategies for valvular heart disease. MEDLINE, Embase, CINAHL, Web of Science, and Business Source Complete were searched using keywords "valvular surgery," "valve disease," "cost-effectiveness," and "cost-benefit analysis". Articles comparing outcomes or costs only were excluded. Search results were uploaded and screened on COVIDENCE. Variables from eligible articles were charted in a spreadsheet.

Results: Twenty articles were eligible, six from low- and middle-income countries (LMICs) and 14 from high-income countries (HICs). In HICs, the top conditions were degenerative aortic valve disease (7/14) and mitral valve disease (4/14) compared to congenital (2/6) and rheumatic heart diseases (2/6) in LMICs. HICs evaluated new technologies and techniques, whereas LMICs compared different valve types or surgery versus no intervention. Most articles used published studies (12/20) or databases (7/20) to conduct their CEA and quality-adjusted life years was the most common effectiveness measure (12/20). Comparator interventions were cost-effective in all LMIC articles and in 8/14 for HICs.

Conclusion: Economic evaluations are mostly conducted in HICs and for adult conditions. More analyses in LMICs are needed. This can be facilitated by maintaining databases, documenting costs, and implementing quality of life assessments.

Background: The aim of this study was to elucidate the clinical impact of the CALLY index in patients with gastric cancer (GC) undergoing gastrectomy.

Methods: Between January 2014 and December 2020, 617 patients who underwent gastrectomy for GC at the Osaka City General Hospital were enrolled in this study. The CALLY index was calculated using the following formula: [albumin (g/dL) × lymphocytes (/μl)]/[CRP (mg/dL) × 10⁴]. We compared the predictive value of four biomarkers [CALLY index, modified Glasgow prognostic score (mGPS), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR)] for short- and long-term outcomes and focused on the CALLY index to elucidate its clinical value.

Results: Receiver operating characteristic analysis showed that the area under the curve for the CALLY index was the highest among the four biomarkers. The 5-year overall survival (OS) and cancer-specific survival (CSS) rates in the low and the high CALLY groups were statistically significant. Multivariate analysis identified the CALLY index as an independent factor for OS and CSS but not NLR or PLR. The mGPS was an independent factor for OS but not for CSS in multivariate analysis. Regarding complications, only the CALLY index was an independent predictor of major complications (≧ Clavien-Dindo grade 3) in multivariate analysis but not others.

Conclusions: The CALLY index may have a clinical value in predicting OS, CSS, and major complications in GC patients undergoing gastrectomy.

Background: Indigenous knowledge healers (IKHs) provide alternative healthcare to formal health services in rural South Africa, but there is a gap in knowledge regarding their treatment of surgical conditions. This study evaluated IKH surgical care and described their perspective of the dual health system.

Methods: A cross sectional survey of IKHs in the Madwaleni Hospital catchment of the Eastern Cape, South Africa was conducted. Topics included the training and experience of IKHs, treatment of nine common surgical conditions, referral patterns, disease origin beliefs, benefits and limitations of care, and collaborative opportunities between the two health systems.

Results: Thirty-five IKHs completed the survey. IKHs were consulted by persons with all nine surgical conditions. The most common forms of treatment were application of an ointment on the affected site (88%) and oral medication (82%). Operative treatment was only done for abscess. Referrals to the formal healthcare sector were made for all surgical conditions. IKHs reported that they were limited by their lack of training and resources to perform operations. On the other hand, they perceived the treatment of the spiritual aspect of surgical disease as a benefit of their care. Thirty-five (100%) IKHs were interested in closer collaboration with the formal health sector.

Conclusion: IKHs treat surgical conditions but refer to the formal health sector when diagnostic and operative services are needed. More research is needed to determine the potential advantages and disadvantages between the formal health sector and IKH collaboration.

Background: Remote-access thyroidectomies have gained popularity, but track recurrence, which is the implantation of thyroid tissue or lesions along the surgical access route, has been reported in case studies. This systematic review aims to review cases of track recurrence following remote-access thyroidectomies.

Methods: A comprehensive literature search was conducted using PubMed, the Web of Science, the Cochrane Library, and Google Scholar to identify case reports on track recurrence after endoscopic or robotic thyroidectomy up to June 2024. Data included patient demographics, details of the initial surgery and diagnosis, methods and timing of recurrence detection, and management strategies.

Results: The search yielded 1578 articles, of which 17 case reports comprising 18 patients were included. The patients (16 females and two males) had a mean age of 34.6 ± 14.9 years. The mean size of initial tumors was 3.9 ± 1.2 cm, with diagnoses of eight cancers and 10 benign lesions. The initial surgeries included 12 endoscopic and six robotic procedures. Track recurrence was most often detected by palpable nodules followed by routine imaging and elevated serum Tg levels. The interval between initial surgery and recurrence ranged from 3 months to 8 years. Management varied from surgical resection and radioactive iodine therapy to close observation. There were no further recurrences in all but one case postoperatively.

Conclusion: Track recurrence after remote-access thyroidectomy is rare but significant. Proper surgical techniques, careful handling of thyroid tissue, and rigorous postoperative monitoring are essential to minimize this risk. Awareness and prompt management of track recurrence may lead to favorable outcomes.

Background: Seroma is the most common complication after breast surgery. Some studies showed that tranexamic acid (TA) can be used in breast surgery to reduce seroma formation and drain volume. We studied the effect of intra-operative and postoperative topical TA on the duration of drain and volume of seroma in patients undergoing axillary lymph node dissection (ALND) for breast cancer.

Patients and methods: Breast cancer patients planned for ALND were enrolled in the study between July 2020 and July 2021. Patients were randomized into three groups where one group (n = 50) received a single intraoperative dose of diluted topical TA, the second group, in addition, received daily postoperative doses till day 5 through the suction drain, and the third group (n = 50) did not receive any dose. Chi-square tests and ANOVA were used to analyze the primary outcomes-the total volume of drain fluid and total drain duration, and secondary outcomes-daily drain output till postoperative-day-5, wound infection, and seroma rates.

Results: Patients receiving multiple doses of topical TA had a decreasing trend in total drain volume, although this was not statistically significant (1597 vs. 1763 vs. 1773 mL: p = 0.269). There was no significant change in the duration of the postoperative drain (21.6 vs. 19.2 vs. 19.55 days: p = 0.54). There was no statistically significant difference in complications between the groups.

Conclusion: There is no significant reduction in drain duration, total drain volume, or the rate of complications with the use of single or multiple doses of topical TA.

Background: Major trauma is a leading cause of death and disability in younger individuals and poses a significant public health concern. There is a growing interest in understanding the complex relationships between socioeconomic deprivation and major trauma. Anecdotal evidence suggests that deprivation is associated with more violent and debilitating injuries. There remains a paucity in literature evaluating major trauma outcomes in relation to socioeconomic deprivation.

Methods: A comprehensive search of MEDLINE, Embase, and CENTRAL databases was performed to identify studies from 1947 to March 2024. The primary outcome was to establish the distribution of injuries based on deprivation, with secondary outcomes evaluating surgical intervention rates, length of stay, and mortality. Quantitative pooling of data was based on the random-effects model.

Results: Fourteen studies and 878,872 trauma patients were included. A substantial proportion (28%) of trauma incidents occurred in the most deprived group. Patients from the lowest socioeconomic group were considerably younger (weighted mean difference [WMD] -9.85 years and 95% confidence intervals [CI] -9.99 to -9.70) and more likely to be male (odds ratio [OR] 1.36 and 95% CI 1.14-1.63). There were no differences in surgical intervention (OR 1.74 and 95% CI 0.97-3.13), length of stay (WMD 1.15 days and 95% CI -0.32-2.62), and mortality (OR 1.04 and 95% CI 0.95-1.14) regardless of background.

Conclusion: Major trauma is prevalent in deprived areas and in younger individuals, with an increasing trend of deprivation in male patients. Although the rates of surgery, length of stay, and mortality did not differ between groups, planning of public health interventions should target areas of higher deprivation.
