Article Synopsis
  • The study investigated the prevalence of preoperative asymptomatic deep vein thrombosis (DVT) in patients undergoing elective general surgery, finding that 10.6% had DVT, with higher rates in those with malignant conditions (13.7%).
  • Significant risk factors for DVT included advanced age (especially over 70 years), female sex, and lower hemoglobin levels, while malignant disease did not independently increase DVT risk.
  • The findings emphasize the need for preoperative DVT screening for all surgical candidates, particularly those with identified risk factors, regardless of whether they have benign or malignant disease.

Background: Risk prediction of anastomotic leakage using anatomical and vascular factors has not been well established. This study aimed to assess the anatomical and vascular factors affecting the hemodynamics of the gastric conduit and develop a novel risk stratification system in patients undergoing esophagectomy with retrosternal reconstruction.

Methods: This retrospective cohort study analyzed 202 patients with esophageal cancer who underwent subtotal esophagectomy with gastric tube retrosternal reconstruction between January 2008 and December 2020.

Objectives: Hepaticojejunostomy anastomotic stricture (HJAS) is a serious adverse event of pancreaticoduodenectomy. Preoperative biliary drainage with a self-expandable metal stent (SEMS) is often performed before pancreaticoduodenectomy. The purpose of this study is to evaluate the risk factors and impact of preoperative SEMS placement on developing benign HJAS after pancreaticoduodenectomy.

Background The prevalence of traditional atherosclerotic risk factors (TARFs) and their association with clinical profiles or mortality in percutaneous coronary intervention remain unclear. Methods and Results The study analyzed 559 452 patients who underwent initial percutaneous coronary intervention between 2012 and 2019 in Japan. TARFs were defined as male sex, hypertension, dyslipidemia, diabetes, smoking, and chronic kidney disease.

Pseudoinvasion is a phenomenon in which adenomatous tissue deviates into the submucosa with the mucosal lamina propria in colorectal epithelial tumors. A relatively large, stalked, neoplastic lesion of the sigmoid colon is considered at high risk of pseudoinvasion. A few reports have described endoscopic mucosal resection or polypectomy for colorectal tumors with pseudoinvasion, but the vertical margins were not sufficiently assessed.

Article Synopsis
  • * A study involving 91 patients undergoing RHB ablation for persistent atrial fibrillation showed significant reductions in both LA volume and EAT volume after 6 months.
  • * Both obese and non-obese patients experienced similar EAT reductions in the pulmonary vein region, and the RHB ablation produced deep lesions affecting EAT, indicating potential long-term changes, but further research is needed to understand its full impact on treatment success.

  • During the COVID-19 pandemic, there was a notable decrease in cardiovascular hospitalizations, with over 10% less in 2020, while in-hospital mortality for certain heart conditions increased.
  • The study analyzed data from 530 hospitals in Japan, finding significant declines in various CVD treatments, including a 30% drop in patients scheduled for left ventricular assist devices.
  • Overall, while the costs related to cardiovascular hospitalizations decreased during the pandemic, the drop in specific procedures like catheter ablation and valvular heart disease contributed significantly to this reduction.

Background Limited data are available about clinical outcomes and residual mitral regurgitation (MR) after transcatheter edge-to-edge repair in the large Asian-Pacific cohort. Methods and Results From the Optimized Catheter Valvular Intervention (OCEAN-Mitral) registry, a total of 2150 patients (primary cause of 34.6%) undergoing transcatheter edge-to-edge repair were analyzed and classified into 3 groups according to the residual MR severity at discharge: MR 0+/1+, 2+, and 3+/4+.

Background The prognostic impact of optical coherence tomography-diagnosed culprit lesion morphology in acute coronary syndrome (ACS) has not been systematically examined in real-world settings. Methods and Results This investigator-initiated, prospective, multicenter, observational study was conducted at 22 Japanese hospitals to identify the prevalence of underlying ACS causes (plaque rupture [PR], plaque erosion [PE], and calcified nodules [CN]) and their impact on clinical outcomes. Patients with ACS diagnosed within 24 hours of symptom onset undergoing emergency percutaneous coronary intervention were enrolled.

Trichobezoars (hair bezoars) are primarily observed in adolescent girls who pull their hair followed by its ingestion. Endoscopic removal of trichobezoars is challenging, and these masses often require surgical removal. Recently, although it has been reported that Coca-Cola could effectively dissolve persimmon phytobezoars, it was ineffective in dissolving trichobezoars.

Background Catheter ablation (CA) for atrial fibrillation (AF) is preferred for paroxysmal AF (PAF) but selectively performed in patients with persistent AF (PersAF). This study aimed to investigate the prognostic differences and consequences of CA based on the AF type. Methods and Results Data from a multicenter AF cohort study were analyzed, categorizing patients as PAF or PersAF according to AF duration (≤7 or >7 days, respectively).

Introduction: Complications of cystectomy and neobladder reconstruction such as anastomotic leakage have been reported. It is a common complication; however, most cases improve conservatively. The use of fibrin glue for fistulas has been reported, but no reports have shown its effectiveness for urinary tract anastomotic leakage.

Aim: Neoadjuvant chemoradiotherapy may improve survival in patients with advanced cholangiocarcinoma. This Phase I study aimed to determine the recommended dose of neoadjuvant chemoradiotherapy and decide whether to move to a Phase II study.

Methods: Patients diagnosed with resectable stage II-IVa cholangiocarcinoma were administered cisplatin (40 [level 0], 50 [level 1 as starting dose], or 60 [level 2] mg/m), 80 mg/m of S-1, and 50.

Objectives: The introduction of artificial intelligence into the medical field has improved the diagnostic capabilities of physicians. However, few studies have analyzed the economic impact of employing artificial intelligence technologies in the clinical environment. This study evaluated the cost-effectiveness of a computer-assisted diagnosis (CADx) system designed to support clinicians in differentiating early gastric cancers from non-cancerous lesions in Japan, where the universal health insurance system was introduced.
