Background: Although abdominal lymph node metastasis in patients with thoracic esophageal squamous cell carcinoma (SCC) has been reported to be a risk factor to reduce long-term survival, only a few studies have so far evaluated the clinicopathologic factors among this group of patients. The purpose of this study was to evaluate the patients' surgical outcome after the clearance of metastatic abdominal nodes.
Patients And Methods: From 1980 to 2002, 550 consecutive patients with thoracic esophageal SCC underwent surgery with an abdominal lymph node dissection. A total of 138 patients with abdominal lymph node metastases were curatively resected. Those patients, including 62 from 1980 to 1989 and 76 from 1990 to 2002, were retrospectively reviewed. Univariate and multivariate analyses were performed to evaluate the impact of clinicopathologic factors on the survival of these patients.
Results: The overall 5-year survival rate of the 138 patients with abdominal lymph node metastases was 23%. A univariate analysis revealed that the following groups showed a greater than 30% overall 5-year survival rate: patients with T1 or T2 tumors, patients without thoracic node metastases, and those with poorly differentiated type tumors. Good prognostic factors based on a multivariate analysis were the most recent time period of surgery and 4 or fewer positive nodes.
Conclusion: Among the patients with abdominal lymph node metastases, those with T1 or T2 tumors, patients without thoracic node metastases, and patients with 4 or fewer positive nodes showed an acceptable overall survival after a curative resection.

Aim: We investigated the short- term results of dynamic/semi-rigid stabilization in patients with cervi-cal spinal stenosis and compare them with patients for which decompression and posterior cer-vical fusion was performed.
Material And Methods: 28 patients were included in this study. Group 1 was the semi-rigid group (four male, ten fe-male), group 2 was the fusion group (nine male, five female).
Coagulation Parameters in Elderly Patients with Severe Pneumonia: Correlation with Disease Severity and Prognosis.
Infect Drug Resist
January 2025
Department of Thoracic Surgery, The Second People's Hospital of Liaocheng, Linqing, Shandong, 252600, People's Republic of China.
Objective: This study aimed to investigate the levels of coagulation parameters in elderly patients with severe pneumonia and analyse their correlation with disease severity and prognosis.
Methods: A retrospective study was conducted on 207 elderly patients (aged ≥60 years) with severe pneumonia admitted to our hospital between January 2022 and December 2023. Demographic data, clinical characteristics and coagulation parameters, including prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time and fibrinogen (FIB), were collected.

Risk factors analysis of hypokalemia after radical resection of esophageal cancer and establishment of a nomogram risk prediction model.
Front Surg
January 2025
Department of Cardio-Thoracic Surgery, The First Affiliated Hospital of Guangxi Medical University, Nanning, Guangxi, China.
Objective: This study aimed to explore the risk factors of hypokalemia after radical resection of esophageal cancer (EC) and establish a nomogram risk prediction model to evaluate hypokalemia risk after esophagectomy. Thus, this study provides a reference for the clinical development of intervention measures.
Methods: Clinical data of EC patients who underwent radical surgery from January 2020 to November 2022 in the First Affiliated Hospital of Guangxi Medical University were retrospectively collected.
Feasibility of ultraportable US in detecting clinically concerning recurrent pneumothorax in patients with chest trauma.
Trauma Surg Acute Care Open

Department of Surgery, Division of Trauma & Acute Care Surgery, Medical College of Wisconsin, Milwaukee, Wisconsin, USA.
Background: Bedside thoracic ultrasound (US) offers numerous advantages over chest X-ray (CXR) for identification of recurrent pneumothoraces (PTX) after tube thoracostomy (TT) removal. Technologic advancements have led to the development of hand-held devices capable of producing high-quality images termed ultra-portable US (UPUS). We hypothesized that UPUS would be as successful as CXR in detecting post-TT removal PTX and would be preferred by patients.
