Purpose:
Finasteride and dutasteride are used to treat benign prostatic hyperplasia (BPH) and reduce the risk of developing prostate cancer. Finasteride blocks only the type 2 form of 5-alpha-reductase, whereas dutasteride blocks both type 1 and 2 forms of the enzyme. Previous studies suggest the possibility that dutasteride may be superior to finasteride in preventing prostate cancer. We directly compared the effects of finasteride and dutasteride on the risk of prostate cancer in patients with BPH using a pooled analysis of 15 real-world databases.
Materials and Methods:
We conducted a multicenter, cohort study of new-users of finasteride and dutasteride. We include patients who were prescribed 5 mg finasteride or dutasteride for the first time to treat BPH and had at least 180 days of prescription. We excluded patients with a history of prostate cancer or a prostate-specific antigen level ≥ 4 ng/mL before the study drug prescription. Cox regression analysis was performed to examine the hazard ratio (HR) for prostate cancer after propensity score (PS) matching.
Results:
A total of 8,284 patients of new-users of finasteride and 8,670 patients of new-users of dutasteride were included across the 15 databases. In the overall population, compared to dutasteride, finasteride was associated with a lower risk of prostate cancer in both on-treatment and intent-to-treat time-at-risk periods. After 1:1 PS matching, 4,897 patients using finasteride and 4,897 patients using dutasteride were enrolled in the present study. No significant differences were observed for risk of prostate cancer between finasteride and dutasteride both on-treatment (HR=0.66, 95% confidence interval [CI]: 0.44–1.00; p=0.051) and intent-to-treat time-at-risk periods (HR=0.87, 95% CI: 0.67–1.14; p=0.310).
Conclusions
Using real-world databases, the present study demonstrated that dutasteride was not associated with a lower risk of prostate cancer than finasteride in patients with BPH.

Purpose:
Tracheal resection with end-to-end anastomosis (TREE) has many advantages over conservative treatment in terms of long-term results; however, this method requires improved safety and accessibility. We aimed to combine expanded venovenous extracorporeal membrane oxygenation (ECMO) during TREE surgery.
Materials and Methods:
Between May 2006 and December 2022, 41 patients diagnosed with tracheal stenosis or tracheal tumors underwent TREE. The non-ECMO and ECMO groups were classified based on the presence or absence of intraoperative ECMO support.
Results:
Reconstruction length was slightly longer in the ECMO group than in the non-ECMO group, but there was no statistical significance (p=0.082). There was no significant difference between the two groups in terms of operative time (p=0.698), estimated blood loss (p=0.210), and duration of mechanical ventilation (p=0.713). There was a significant difference in intensive care unit stay between the two groups (p=0.013) due to the postoperative maintenance of ECMO. There were no cases of early mortality in either group during hospitalization (p>0.999).
Conclusion
ECMO support could assist in more challenging cases as it makes surgery easier in difficult patient scenarios.

Gut and Liver 2025;19(3):427-437
Background/Aims:
This study aimed to evaluate the performance of the Model for End-Stage Liver Disease (MELD) 3.0 for predicting mortality and liver-related complications compared with the Child-Pugh classification, albumin-bilirubin (ALBI) grade, the MELD, and the MELD sodium (MELDNa) score.
Methods:
We evaluated a multicenter retrospective cohort of incorporated patients with cirrhosis between 2013 and 2019. We conducted comparisons of the area under the receiver operating characteristic curve (AUROC) of the MELD3.0 and other models for predicting 3-month mortality. Additionally, we assessed the risk of cirrhosis-related complications according to the MELD3.0 score.
Results:
A total of 3,314 patients were included. The mean age was 55.9±11.3 years, and 70.2% of the patients were male. Within the initial 3 months, 220 patients (6.6%) died, and the MELD3.0had the best predictive performance among the tested models, with an AUROC of 0.851, outperforming the Child-Pugh classification, ALBI grade, MELD, and MELDNa. A high MELD3.0score was associated with an increased risk of mortality. Compared with that of the group with a MELD3.0 score <10 points, the adjusted hazard ratio of the group with a score of 10–20 pointswas 2.176, and that for the group with a score of ≥20 points was 4.892. Each 1-point increase inthe MELD3.0 score increased the risk of cirrhosis-related complications by 1.033-fold. The risk of hepatorenal syndrome showed the highest increase, with an adjusted hazard ratio of 1.149, followed by hepatic encephalopathy and ascites.
Conclusions
The MELD3.0 demonstrated robust prognostic performance in predicting mortality in patients with cirrhosis. Moreover, the MELD3.0 score was linked to cirrhosis-related complications, particularly those involving kidney function, such as hepatorenal syndrome and ascites.

Journal of Gastric Cancer 2025;25(2):318-329
Purpose:
The optimal reconstruction method following distal gastrectomy has not been elucidated. Since Billroth-II (B-II) reconstruction is commonly associated with increased bile reflux, Braun jejunojejunostomy has been proposed to reduce this complication.
Materials and Methods:
We retrospectively analyzed 325 patients with gastric cancer who underwent distal gastrectomy with B-II reconstruction between January 2015 and December 2017, comprising 159 patients without Braun anastomosis and 166 with Braun anastomosis.Outcomes were assessed over three years using annual gastroscopy based on the residual food, gastritis, and bile reflux criteria and the Los Angeles classification for reflux esophagitis.
Results:
In the first postoperative year, the group with Braun anastomosis showed a significant reduction in bile reflux compared to the group without Braun anastomosis (75.9% vs. 86.2%; P=0.019). Moreover, multivariate analysis identified Braun anastomosis as the sole factor associated with this outcome. Additionally, the group with Braun anastomosis had a lower incidence of heartburn (12.0% vs. 20.1%; P=0.047) and reduced use of prokinetics (P<0.001) and acid reducers (P=0.002) compared to the group without Braun anastomosis.However, these benefits diminished in subsequent years, with no significant differences in residual food, gastritis, or reflux esophagitis between the groups. Both groups showed similar body mass index scores and nutritional outcomes over the 3-year follow-up period.
Conclusions
Although Braun anastomosis offers short-term benefits in reducing bile reflux after B-II reconstruction, these effects are not sustainable. The routine use of Braun anastomosis should be reconsidered, though either approach remains a viable option depending on the patient’s circumstances.
