Abstract

Objective:

To systematically evaluate differences in swallowing disorder-related manifestations in patients with supraglottic laryngeal cancer, who underwent traditional open partial horizontal laryngectomy (OPHL) and endoscopic supraglottic laryngectomy (ESL).

Methods:

A systematic review of the literature and a meta-analysis were performed. The CNKI, Wan Fang, PubMed, EMBASE, Cochrane Library, Web of Science, and Clinical Trials databases for clinical studies data sources were investigated. The efficiency of recovery, postoperative swallowing function, and complications related to dysphagia were investigated to compare the effects of surgical procedures.

Results:

The meta-analysis included 8 studies with 281 patients. ESL surgery played a positive role in the recovery of patients. Preservation of the anterior epiglottic space, ventricular band, and arytenoid cartilage without destroying the external framework of the larynx can effectively reduce the risk of aspiration pneumonia in patients.

Conclusions:

ESL has advantages in postoperative recovery and retention of swallowing function in patients with supraglottic laryngeal cancer.

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Barrett Esophagus-II: Clinical Manifestations and Management

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...
