At the occasion of 15,000 high endoscopies performed during the past 5 years at the general Hospital of Dakar (Senegal) 38 mucous diaphragms of cervical esophagus were discovered. 36 patients are Black Senegalese; 29 females and 9 males with a mean age of 37. Dysphagia was present 29 times and anemia 22 times. Endoscopies diagnosis is easy, putting into light a mucous diaphragm at the level or immediately below Killian mouth. 18 of these cases have been classified as Kelly-Paterson syndrome. Performed in 30 patients, the treatment consists in breaking down the mucous diaphragm with an endoscope. It is difficult to keep on endoscopic monitoring, although it is essential because the risk of cancerisation.

Delineation of reduced CTV2 on the basis of the characteristics and distribution of cervical lymph node metastasis in nasopharyngeal carcinoma.
BMC Cancer
January 2025
Department of Radiation Oncology, First Affiliated Hospital of Kunming Medical University, 295 Xichang Road, Kunming, 650032, P. R. China.
Introduction: The core objective of this study was to precisely locate metastatic lymph nodes, identify potential areas in nasopharyngeal carcinoma patients that may not require radiotherapy, and propose a hypothesis for reduced target volume radiotherapy on the basis of these findings. Ultimately, we reassessed the differences in dosimetry of organs at risk (OARs) between reduced target volume (reduced CTV2) radiotherapy and standard radiotherapy.
Methods And Materials: A total of 209 patients participated in the study.
Differences in Transdiaphragmatic Pressure of Dogs Suffering from Cervical or Thoracolumbar Myelopathy Anaesthetised with Isoflurane.
Animals (Basel)
January 2025
Anaesthesia and Intensive Care Unit, Companion Animal Clinic, School of Veterinary Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, 54627 Thessaloniki, Greece.
Background: The purpose of this study is to evaluate differences in transdiaphragmatic pressure (Pdi) in dogs suffering from cervical myelopathy (CM) and thoracolumbar myelopathy (TLM) anaesthetised with isoflurane (ISO).
Methods: This prospective cohort study included ASA II-status dogs diagnosed with either CM or TLM, anaesthetised for diagnostic or surgical purposes between September 2021 and July 2023. Patients followed the same anaesthetic protocol, and maximum Pdi was recorded at 10 (Pdimax10), 20 (Pdimax20), and 30 (Pdimax30) minutes using balloon catheters placed in the stomach (Pgast) and in the mid-third of the oesophagus (Poes).
Feasibility and safety of endoscopic submucosal dissection for superficial cancer of the remnant esophagus after esophagectomy.
Esophagus
January 2025
Department of Gastroenterology and Hepatology, Osaka University Graduate School of Medicine, 2-2 Yamadaoka, Suita, Osaka, 565-0871, Japan.
Background: Endoscopic treatment for second primary malignancies after esophagectomy has been increasingly performed; however, evidence regarding the outcomes of endoscopic submucosal dissection (ESD) for superficial cancer of the remnant esophagus after esophagectomy (SCREE) is limited.
Methods: We retrospectively extracted cases of ESD for SCREE from our institutional database, which included 739 consecutive esophageal ESD procedures performed between January 2009 and September 2023. Information on prior treatment, clinical features of the lesions, and outcomes was evaluated.

Department of Medical Oncology, National Taiwan University Cancer Center, 7 Chung-Shan South Road, Taipei, 10002, Taiwan.
Esophageal squamous cell carcinoma (ESCC) is a prevalent and highly lethal malignancy in Asia. Recent advancements in immune checkpoint inhibitors (ICIs) have markedly transformed the systemic therapy landscape for ESCC. Anti-PD-1-based combination with chemotherapy or with ipilimumab, an anti-CTLA-4 antibody, have been established as the new standard first-line treatments for patients with advanced ESCC.

Background: Digestive system perforations after anterior cervical spine surgery (ACSS), if left untreated, are life-threatening. These injuries are often categorized as pharyngoesophageal. Although the pharynx and esophagus are continuations of each other, they are two distinct anatomical structures.
