Background: Enhanced recovery after surgery (ERAS) protocols are proposed to enhance perioperative care, but their impact on various surgical outcomes requires further insight. Objective: This extensive meta-analysis aimed to systematically estimate the effectiveness of ERAS in reducing postoperative complications and improving recovery metrics. Materials and Methods: We meticulously searched multiple databases and rigorously screened studies, ultimately including 16 high-quality research articles in our meta-analysis. We carefully assessed heterogeneity using the Cochran Q test and I² index. Results were visualized using forest plots, displaying effect sizes and 95% confidence intervals (CIs). Results: The current meta-analysis reveals compelling evidence of ERAS protocols' impact on postoperative effects. Lung infection rates were significantly reduced, with an odds ratio (OR) of 0.4393 (95% CI: 0.2674; 0.7216, p = 0.0012), highlighting the protocols' effectiveness. Although the reduction in surgical site infections (SSIs) was not significant, with an OR of 0.8003 (95% CI: 0.3908; 1.6389, p = 0.5425), the data suggests a trend toward benefit. Urinary tract infections (UTI) also showed a promising decrease, with an OR of 0.4754 (95% CI: 0.2028; 1.1143, p = 0.0871), revealing ERAS protocols may mitigate UTI risks. No significant effects were observed on postoperative anastomotic leakage or ileus, with ORs indicating neutrality. The incidence of readmission was similarly unaffected, with an OR of 1.4018 (95% CI: 0.6860; 2.8647, p = 0.3543). These outcomes underscore the selective efficacy of ERAS protocols, advocating for their strategic implementation to optimize surgical recovery. Conclusions: This meta-analysis offers compelling evidence supporting the implementation of ERAS in mitigating specific post-surgical conditions. It underscores the potential of ERAS to enhance recovery experiences and improve healthcare efficiency. Further targeted research is warranted to fully understand the impact of ERAS on SSI, anastomotic leakage, ileus, and readmissions and to optimize its benefits across diverse surgical populations.

Introduction: Total cystectomy and hepatectomy are the main radical surgical procedures for hepatic cystic echinococcosis (CE). When CE lesions severely invade intrahepatic biliary ducts and vessels or single or multiple lesions occupy one hepatic lobe, performing total cystectomy is not indicated. This study aimed to analyze the clinical efficiency of anatomical hepatectomy in the treatment of patients with hepatic CE. Methods: Clinical data of 74 patients with hepatic CE who received anatomical hepatectomy were retrospectively analyzed from January 2005 to January 2022. The patients were classified into the intrahepatic biliary duct invasion group (group A), the intrahepatic vessel invasion group (group B), and the hepatic lobe occupation group (group C). Results: Among these 74 patients who received anatomical hepatectomy, right hepatectomy was performed in 20 cases (27.03%), left hepatectomy in 26 cases (35.13%), right posterior lobectomy in nine cases (12.16%), and left lateral sectionectomy in 19 cases (25.68%). Short-term post-operative complications occurred in seven cases (9.50%), including abdominal abscess in one case, pleural effusion in three cases, intestinal obstruction in one case, incision infection in one case, and ascites in one case. Long-term post-operative complications occurred in four cases (5.4%), including recurrences of CE in two cases and incisional hernias in another two cases. There were no statistical differences in the concentrations of total bilirubin, alanine aminotransferase, and aspartic transaminase before and after surgery between groups (p > 0.05). However, differences in operative time, short-term post-operative complications, average hospital stay, and number of open hepatectomy cases were statistically significant between groups (p < 0.05). The differences in cases receiving hepatic portal occlusion, intra-operative blood loss, and intra-operative blood transfusion were not statistically significant between groups (p > 0.05). Conclusions: Anatomical hepatectomy is an effective and feasible surgical procedure for patients with hepatic CE with severe invasion of intrahepatic biliary ducts and vessels or patients with huge lesions occupying one hepatic lobe, which effectively avoids residual cavity-related complications.

Objective: This study investigates the practicability of serum kallistatin as a biomarker in the diagnosis of tubo-ovarian abscess (TOA) because C-reactive protein (CRP) is insufficiently specific for diagnosis. Methods: Thirty patients (control group) who presented for elective gynecological surgeries and 30 who were hospitalized due to TOA (study group) at the Antalya Training and Research Hospital Gynecology Clinic, Türkiye, between January 1 and December 31, 2022, were included in the study. Blood samples were collected for the calculation of complete blood count, biochemistry, CRP, and serum kallistatin values, and the results were recorded in a database. Results: Although no significant differences were observed between the control and study groups in terms of age or body mass index, significant differences were observed in terms of marital status, number of pregnancies, parity number, intrauterine device history, and previous surgical history (p > 0.05). Serum hemoglobin levels (12.61 ± 1.30 vs. 11.47 ± 1.77; p = 0.008), white blood cell (7.9 [6.15 ± 9.7] vs. 17.0 [11.6-19.6]; p < 0.001), neutrophil (4.6 [3.6-6.12] vs. 13.6 [9.25-16.1]; p < 0.001), lymphocyte (2.51 ± 0.71 vs. 2.33 ± 0.69; p = 0.307), and platelet counts (285.63 ± 78.0 vs. 407.03 ± 131.96; p < 0.001), neutrophil-lymphocyte ratio (2.11 ± 0.93 vs. 6.18 ± 2.20; p < 0.001), neutrophil-lymphocyte ratio (123.16 ± 52.63 vs. 184.39 ± 63.90; p < 0.001), hs-CRP (1.20 [5.55-1.92] vs. 240 [138.25-291.0]; p < 0.001), kallistatin (7.18 ± 3.15 vs. 3.83 ± 3.69; p = 0.006), and urine leukocyte values (1 [0.75-3] vs. 3 [1-6.5]; p = 0.038) also differed significantly between the control and study groups. Conclusion: The study findings show that serum kallistatin levels can be used as a biomarker in the diagnosis of TOA. Further studies involving more participants are now needed to test the accuracy of our results.

Histoplasmosis is an increasing infection that mainly affects immunocompromised individuals such as patients with HIV/AIDS, with the disseminated form, especially gastrointestinal, being common in this population. The clinical presentation ranges from asymptomatic to symptoms that mimic other abdominal diseases. Jejunal perforation due to histoplasmosis, although rare, has been reported in a few cases, typically in men living with HIV in their fourth decade of life. We present the case of a 34-year-old male, with a history of HIV and colonic histoplasmosis who presented with acute abdominal pain requiring exploratory laparotomy and intestinal resection due to jejunal perforation, with histological confirmation of histoplasmosis in the resected intestinal segment.

Background: Lack of insurance is associated with poorer outcomes in hospitalized patients. However, few studies have explored this association in hospitalizations for necrotizing soft tissue infections (NSTIs). This study examined the impact of insurance status on the outcome of NSTI admissions. Methods: All adult hospitalizations for necrotizing fasciitis, gas gangrene, and Fournier gangrene between 2016 and 2018 were examined using the Nationwide Inpatient Sample database. Insurance status was categorized as insured (including Medicare, Medicaid, and Private, including Health maintenance organization (HMO) or uninsured (Self-pay). Outcome measures included mortality rates, limb loss, length of hospital stay, prolonged hospital stay, and critical care admissions. Statistical analysis included weighted sample analysis, chi-square tests, multivariate regression analysis, and negative binomial regression modeling. Results: Approximately 29,705 adult hospitalizations for NSTIs were analyzed. Of these, 57.4% (17,065) were due to necrotizing fasciitis, 22% (6,545) to gas gangrene, and 20.5% (6,095) to Fournier gangrene. Approximately 9.7% (2,875) were uninsured, whereas 70% (26,780) had insurance coverage. Among the insured, Medicare covered 39.6% (10,605), Medicaid 29% (7,775), and private insurance 31.4% (8,400). After adjustments, Medicare insurance was associated with greater odds of mortality (adjusted odds ratio [aOR]: 1.81; 95% confidence interval [CI]: 1.33-2.47; p = 0.001). Medicaid insurance was associated with increased odds of amputation (aOR: 1.81; 95% CI: 1.33-2.47; p < 0.001), whereas private insurance was associated with lower odds of amputation (aOR: 0.70; 95% CI: 0.51-0.97; p = 0.030). Medicaid insurance was associated with greater odds of prolonged hospital stay (aOR: 1.34; 95% CI: 1.09-1.64; p < 0.001). No significant association was observed between the lack of insurance or self-pay and the odds of primary or secondary outcomes. Conclusion: Medicare insurance was correlated with greater odds of mortality, whereas Medicaid insurance was associated with increased odds of amputation and longer hospital stay. Uninsured status was not associated with significant differences in NSTI outcomes.

Background: Antibiotics are frequently administered prophylactically to trauma patients with various injury patterns to prevent infectious complications. Trauma patients may also require large volume resuscitation with blood products. Limited data are available to support antibiotic dosing recommendations in this population. We hypothesized that we would be able to develop a population pharmacokinetic model of cefazolin, a frequently used antibiotic in the trauma scenario, from remnant blood samples by pharmacokinetic analysis of trauma patients. Methods: Remnant plasma from standard of care chemistry/hematology assessments was retrieved within 48 h of collection and assayed to determine cefazolin concentrations. Population pharmacokinetic analyses were conducted in Pmetrics using R. Linear regression was conducted to assess the effect of blood product resuscitation volume on cefazolin pharmacokinetic parameters. Results: Cefazolin concentrations best fitted a two-compartment model (Akaike information criterion: 443.9). The mean ± standard deviation parameters were total body clearance (4.3 ± 1.9L), volume of the central compartment (V_c: 7.7 ± 6.9L), and intercompartment transfer constants (k₁₂: 1.3 ± 0.98 h^-1, k₂₁: 0.6 ± 0.45 h^-1). No statistical relationships were observed between blood products, volume of blood products, and cefazolin clearance or V_c (R²: 0.0004-0.21, p = 0.08-0.95). Using a 5,000-patient Monte Carlo simulation, 2 g with repeated dosing every 2 h until end of surgery was required to achieve 93.2% probability of 100% free time above the minimum inhibitory concentration (MIC) (fT > MIC) at the ECOFF value for Staphylococcus aureus (2 mg/L). Conclusions: In these 15 trauma patients receiving blood transfusion, no relationship with blood volume resuscitation and cefazolin pharmacokinetics was observed. On the basis of this pharmacokinetic model, frequent cefazolin doses are required to maintain 100% fT > MIC.

Background: The objective of this study was to investigate the association between pre-operative body mass index (BMI) and surgical infection in perihilar cholangiocarcinoma (pCCA) patients treated with curative resection. Methods: Consecutive pCCA patients were enrolled from four tertiary hospitals between 2008 and 2022. According to pre-operative BMI, the patients were divided into three groups: low BMI (≤18.4 kg/m²), normal BMI (18.5-24.9 kg/m²), and high BMI (≥25.0 kg/m²). The incidence of surgical infection among the three groups was compared. Multivariable logistic regression models were used to determine the independent risk factors associated with surgical infection. Results: A total of 371 patients were enrolled, including 283 patients (76.3%) in the normal BMI group, 30 patients (8.1%) in the low BMI group, and 58 patients (15.6%) in the high BMI group. The incidence of surgical infection was significantly higher in the patients in the low BMI and high BMI groups than in the normal BMI group. The multivariable logistic regression model showed that low BMI and high BMI were independently associated with the occurrence of surgical infection. Conclusions: The pCCA patients with a normal BMI treated with curative resection could have a lower risk of surgical infection than pCCA patients with an abnormal BMI.
