The investigation was undertaken to estimate the possibilities of the current ultrasound study (USS) in patients with esophageal cancer for its specifying diagnosis and the evaluation of the efficiency of performed treatment. The paper gives data on the current possibilities of ultrasound diagnosis in patients with esophageal cancer, which, during one study, makes it possible to visualize the tumor, to characterize its sizes and structure, to reveal enlarged regional lymph nodes, and to evaluate the oropharynx and abdominal organs. A definite USS program was used to examine 54 patients with verified esophageal cancer (42 (77.8%) men and 12 (22%) women aged 53 to 76 years). The patients' mean age was 65.3 +/- 4.8 years. The upper, middle, and lower esophagus was involved in 7 (13%), 41 (76%), and 6 (11%) patients, respectively. Most examinees had stages III and IV, received combined chemoradiation therapy. There was satisfactory and good visualization of middle esophageal tumor in 88% of the patients. USS identified enlarged paraesophageal lymph nodes in 22%. Enlarged nodes in the neck and supra- and subclavicular areas were detected in 16 (30%) patients, including 10 patients with stage IVa.

Objective: To investigate the clinical manifestations of head and neck cancer in patients with Plummer-Vinson syndrome (PVS) and to assess related oral comorbidities.
Materials And Methods: Case reports covering head and neck cancer manifestations in patients diagnosed with PVS were included Studies were identified through seven main electronic databases (PubMed/MEDLINE, EMBASE, Scopus, Web of Science, CINAHL, LILACS, and LIVIVO), and a search for gray literature was performed using ProQuest Dissertations and Theses and Google Scholar. Independent reviewers applied predefined eligibility criteria in a two-phase selection process.
Robotic esophagectomy with function-preserving radical mediastinal lymphadenectomy for esophageal cancer.
Ann Gastroenterol Surg
January 2025
Radical lymphadenectomy is the critical component of surgery for esophageal cancer. However, lymphadenectomy significantly contributes to postoperative morbidity, particularly in terms of pulmonary complications following esophagectomy. Function-preserving mediastinal lymphadenectomy seeks to balance the procedure's necessary radicality and optimal functional outcomes.

Background: The advantages of robot-assisted minimally invasive esophagectomy (RA-MIE) over conventional minimally invasive esophagectomy (C-MIE) are unknown. This nationwide large-scale study aimed to compare surgical outcomes between RA-MIE and C-MIE using rigorous propensity score methods, including detailed covariates and relevant outcomes.
Methods: This Japanese nationwide retrospective cohort study included RA-MIE or C-MIE for esophageal malignant tumors performed between October 2018 and December 2019 and registered in the Japanese National Clinical Database.

Esophageal cancer is the eighth most common cancer worldwide and the sixth leading cause of cancer-related deaths. In this study, we propose a novel esophageal stent equipped with a wireless, battery-free, and movable photodynamic therapy (PDT) unit designed to treat esophageal tumors with flexibility, precision, and real-time control. This system integrates a PDT unit and an electrochemical pneumatic soft actuator into a conventional esophageal stent.
