Background:
In intensive care settings, the maintenance of ventilation is typically essential. Tracheostomy is frequently performed to facilitate long-term ventilation and to minimize associated complications. This procedure can be conducted using several techniques, including traditional surgery, endoscopic approaches, and ultrasound-guided methods.
Methods:
We retrospectively examined data from all patients admitted to the intensive care unit of our institution who underwent ultrasound-guided percutaneous tracheostomy (UPCT) between March 2018 and April 2023. The study included a total of 81 patients aged 15 years or older. To assess the incidence of complications, we classified these issues as either minor or major, with major complications encompassing events such as bleeding necessitating blood transfusion.
Results:
The most frequent minor complication was bleeding that did not require blood transfusion, which occurred in 15 patients (18.5%). Major complications were identified in 7 patients (8.6%), all of whom experienced bleeding that necessitated transfusion. However, we noted no cases of infection, conversion to open surgery, or tracheal stenosis surgery.The complication rate did not significantly differ from those reported in previous studies.
Conclusion
These results indicate that UPCT can be safely used in critically ill patients, although further research on this topic is needed.

Diaphragmatic fibromatosis is an exceptionally rare condition, with only 2 previously reported cases in the literature. We present the case of a 23-year-old woman with a left hypochondrial swelling measuring 19×18×13 cm on computed tomography. An endoscopic ultrasound-guided biopsy indicated low-grade papillary proliferation. Surgical exploration revealed a large mass originating from the left hemidiaphragm. Complete excision of the mass and reconstruction of the diaphragm with double-layer mesh were performed.Microscopic examination of the mass revealed a bland-looking spindle cell proliferation.Immunohistochemical staining showed a positive nuclear reaction in tumor cells for β-catenin, a focal positive reaction for SMA, and negative reactions for S100, CD34, and desmin.Diaphragmatic fibromatosis is an extremely rare tumor for which complete excision and reconstruction of the diaphragm is the best suggested modality of treatment.

Background:
Delayed hemothorax (dHTX) can occur unexpectedly, even in patients who initially present without signs of hemothorax (HTX), potentially leading to death. We aimed to develop a predictive model for dHTX requiring intervention, specifically targeting those with no or occult HTX.
Methods:
This retrospective study was conducted at a level 1 trauma center. The primary outcome was the occurrence of dHTX requiring intervention in patients who had no HTX or occult HTX and did not undergo closed thoracostomy post-injury. To minimize overfitting, we employed the least absolute shrinkage and selection operator (LASSO) logistic regression model for feature selection. Thereafter, we developed a multivariable logistic regression (MLR) model and a nomogram.
Results:
In total, 688 patients were included in the study, with 64 cases of dHTX (9.3%).The LASSO and MLR analyses revealed that the depth of HTX (adjusted odds ratio [aOR], 3.79; 95% confidence interval [CI], 2.10–6.85; p<0.001) and the number of totally displaced rib fractures (RFX) (aOR, 1.90; 95% CI, 1.56–2.32; p<0.001) were significant predictors. Based on these parameters, we developed a nomogram to predict dHTX, with a sensitivity of 78.1%, a specificity of 76.0%, a positive predictive value of 25.0%, and a negative predictive value of 97.1% at the optimal cut-off value. The area under the receiver operating characteristic curve was 0.832.
Conclusion
The depth of HTX on initial chest computed tomography and the number of totally displaced RFX emerged as significant risk factors for dHTX. We propose a novel nomogram that is easily applicable in clinical settings.

Background:
This study aimed to evaluate the long-term impact of postoperative prolonged air leak (PAL) on pulmonary function.
Methods:
We enrolled 1,316 patients with pathologic stage I–III lung cancer who underwent lobectomy. The cohort was divided into 2 groups: those who experienced PAL (n=55) and those who did not (n=1,261). Propensity score matching was conducted at a 1:4 ratio, resulting in 49 patients in the PAL group and 189 in the non-PAL group. Changes in pulmonary function were compared among preoperative, 6-month postoperative, and 12-month postoperative measurements between the 2 groups.
Results:
The variables used for propensity score matching included age, sex, smoking history, body mass index, baseline pulmonary function, pathologic stage, and surgical approach. All standardized mean differences were less than 0.1. Six months postoperatively, the PAL group showed a greater reduction in both forced expiratory volume in 1 second(FEV1 ) (-13.0% vs. -10.0%, p=0.041) and forced vital capacity (FVC) (-15.0% vs. -9.0%, p<0.001)than the non-PAL group. In cases of upper lobectomy, there were no significant differencesin FEV 1 changes between the PAL and non-PAL groups at both 6 and 12 months. However, in lower lobectomy, the PAL group demonstrated a more pronounced decrease in FEV1(-14.0% vs. -11.0%, p=0.057) and FVC (-20.0% vs. -13.0%, p=0.006) than the non-PAL group at 6 months postoperatively.
Conclusion
Postoperative PAL delayed the recovery of pulmonary function after lobectomy. These effects were markedly more pronounced after lower lobectomy than after upper lobectomy.

Background:
This study compared the costs associated with transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) in Korea by utilizing the National Health Insurance Service database.
Methods:
Between June 2015 and May 2019, 1,468 patients underwent primary isolated transfemoral TAVI, while 2,835 patients received primary isolated SAVR with a bioprosthesis. We assessed the costs of index hospitalization and subsequent healthcare utilization, categorizing the cohort into 6 age subgroups: <70, 70–74, 75–79, 80–84, 85–89, and ≥90 years. The median follow-up periods were 2.5 and 3.0 years in the TAVI and SAVR groups, respectively.
Results:
The index hospitalization costs were 41.0 million Korean won (KRW) (interquartile range [IQR], 39.1–44.7) for the TAVI group and 24.6 million KRW (IQR, 21.3–30.2) for the SAVR group (p<0.001). The TAVI group exhibited relatively constant index hospitalization costs across different age subgroups. In contrast, the SAVR group showed increasing index hospitalization costs with advancing age. The healthcare utilization costs were 5.7 million KRW per year (IQR, 3.3–14.2) for the TAVI group and 4.0 million KRW per year (IQR, 2.2–9.0) for the SAVR group (p<0.001). Healthcare utilization costs were higher in the TAVI group than in the SAVR group for the age subgroups of <70, 70–74, and 75–79 years, and were comparable in the age subgroups of 80–84, 85–89, and ≥90 years.
Conclusion
TAVI had much higher index hospitalization costs than SAVR. Additionally, the overall healthcare utilization costs post-discharge for TAVI were also marginally higher than those for SAVR in younger age subgroups.

Background:
Using a previously unreported Peruvian registry of patients treated for early-stage non-small cell lung cancer (NSCLC), this study explored whether wedge resection and lobectomy were equivalent regarding survival and impact on radiologic-pathologic variables.
Methods:
This observational, analytical, longitudinal study used propensity scorematched (PSM) analysis of a single-center retrospective registry of 2,570 patients with pathologic stage I–II NSCLC who were treated with wedge resection (n=1,845) or lobectomy (n=725) during 2000–2020. After PSM, 650 cases were analyzed (resection, n=325;lobectomy, n=325) through preoperative and clinical variables, including patients with ≥1 lymph node removed. Kaplan-Meier curves and multivariable Cox proportional hazard models were created for 5-year overall survival (OS), disease-free survival (DFS), and locoregional-recurrence-free survival (LRFS).
Results:
The principal complication was operative pain persisting >7 days for lobectomy versus wedge resection (58% vs. 23%, p=0.034) and shorter hospital stays for resection than for lobectomy (5.3 days vs. 12.8 days, p=0.009). The 5-year OS (84.3% vs. 81.2%, p=0.09) and DFS (79.1% vs. 74.1%, p=0.07) were similar and statistically insignificant between resections and lobectomies, respectively. LRFS was worse overall following wedge resection than lobectomy (79.8% vs. 91.1%, p<0.02). Nevertheless, in the PSM analysis, both groups experienced similar LRFS when the resection margin was >10 mm (90.9% vs. 87.3%, p<0.048) and ≥4 lymph nodes were removed (82.8% vs. 79.1%, p<0.011).
Conclusion
Both techniques led to similar OS and DFS at 5 years; however, successful LRFS required a wedge resection with a surgical margin and adequate lymph node removal to obtain outcomes similar to lobectomy.
