Summary
Thyroidectomy may worsen laryngopharyngeal reflux (LPR) symptoms and findings, with scores peaking post-surgery. Proton pump inhibitors can help manage these LPR changes after thyroid surgery.
Area of Science:
- Otolaryngology
- Gastroenterology
- Endocrinology
Background:
- Laryngopharyngeal reflux (LPR) is a suspected cause of post-thyroidectomy syndrome.
- The relationship between thyroidectomy and LPR requires further investigation.
Purpose of the Study:
- To evaluate the correlation between thyroidectomy and LPR.
- To assess changes in LPR symptoms and laryngoscopic findings pre- and post-thyroidectomy.
Main Methods:
- Ninety-five patients undergoing thyroidectomy were assessed.
- Reflux Finding Score (RFS) and Reflux Symptom Index (RSI) were measured pre-surgery and at 2, 4, 6, and 12 months post-surgery.
- Effect of proton pump inhibitors on RFS and RSI was evaluated.
Main Results:
- RFS scores significantly increased post-thyroidectomy, returning to baseline by 12 months.
- RSI scores showed a non-significant increase post-surgery, gradually decreasing over 12 months.
- Proton pump inhibitor administration improved both RSI and RFS scores.
Conclusions:
- Uncomplicated thyroidectomy can exacerbate LPR-related laryngoscopic findings.
- Further research with pH-monitoring and manometry is needed to understand LPR deterioration and upper esophageal sphincter pressure changes post-thyroidectomy.

01:29Gastroesophageal Reflux Disease I: Meaning and Pathophysiology
637
Gastroesophageal Reflux Disease (GERD) involves the recurrent backflow of the stomach or duodenal contents into the esophagus, leading to troublesome symptoms and potential esophageal mucosal damage. Although GERD is often referred to as a disease, it is more accurately described as a syndrome, as it encompasses a range of symptoms and complications rather than a singular pathological entity, impacting a large number of individuals as the most prevalent upper gastrointestinal problem. Roughly...

01:21Barrett Esophagus-II: Clinical Manifestations and Management
362
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...

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...

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
