In Vivo Tissue Temperature Characteristics of Contact Force Catheter With a Mesh-Shaped Irrigation Tip: A Porcine Study.
Pacing Clin Electrophysiol
January 2025
Section of Laboratory for Animal Experiments, Institute of Medical Science, Medical Research Support Center, Nihon University, School of Medicine, Tokyo, Japan.
Background: Neither the actual in vivo tissue temperatures reached with a novel contact force sensing catheter with a mesh-shaped irrigation tip (TactiFlex SE, Abbott) nor the safety profile has been elucidated.
Methods: In a porcine model (n = 8), thermocouples were implanted epicardially in the superior vena cava, right pulmonary vein, and esophagus close to the inferior vena cava following a right thoracotomy. After chest closure, endocardial ablation was conducted near the thermocouples under fluoroscopic guidance.
Blunt trauma-induced complete esophageal avulsion: A case report on surgical intervention and clinical insights.
Trauma Case Rep
December 2024
Northeast Georgia Medical Center, Trauma and Acute Care Surgery Department, Gainesville, GA 30501, USA.
Blunt esophageal injury is an exceptionally rare condition, with complete esophageal avulsion being almost unprecedented in adults. This case study details the clinical presentation, surgical management, and postoperative course of a 50-year-old male who sustained a complete esophageal avulsion following blunt abdominal trauma. The patient presented with increasing abdominal pain two hours after falling while stepping up onto a high truck step, striking his upper abdomen on the step.

Langenbecks Arch Surg
December 2024
Department of General Surgery, Huashan Hospital, Fudan University, No. 12 Middle Urumqi Road, Shanghai, 200040, China.
Background: Laparoscopic total gastrectomy (LTG) is still limited because intracorporeal oesophagojejunostomy is technically demanding and difficult in laparoscopic gastrectomy. Circular-stapled anastomosis is considered the "gold standard" method for oesophagojejunostomy in open total gastrectomy. A purse-string suture instrument is used to create a purse-string suture along the distal oesophagus as a standard technique for classic circular-stapled oesophagojejunostomy in the open total gastrectomy.

Plast Reconstr Surg Glob Open
November 2024
Division of Otolaryngology-Head and Neck Surgery, Dalhousie University, Halifax, Nova Scotia, Canada.
Background: Management of esophageal cancer is complex. Esophagectomy is associated with risk of significant complications. In this case series, we share the experience of our multidisciplinary team of thoracic surgeons and otolaryngologists in managing complications arising in the surgical treatment of esophageal cancer with the assistance of regional tissue transfer in the form of the pectoralis major flap.

Surg Clin North Am

University of Massachusetts Chan Medical School, Baystate Medical Center, Springfield, MA, USA. Electronic address:
Achalasia is an incurable condition of the esophagus involving the inflammation and degeneration of inhibitory neurons of the lower esophageal sphincter (LES) resulting in failure of the LES to relax. Typical symptoms of achalasia are dysphagia, retrosternal chest pain, regurgitation, and weight loss. Three studies are typically required for the diagnosis of achalasia: barium swallow, high-resolution esophageal manometry, and esophagogastroduodenoscopy.
