Esophageal Strictures-II: Clinical Features and Management01:26

Esophageal Strictures-II: Clinical Features and Management

127
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...

Summary

A new risk model helps predict feeding tube dependence after tongue reconstruction surgery. This tool aids surgeons in estimating patient risk before the procedure, improving outcomes for oral cancer patients.

Area of Science:

  • Oncology
  • Surgical Reconstruction
  • Medical Informatics

Background:

  • Outcomes of tongue reconstruction lack consensus.
  • A novel risk model was developed to predict postoperative dysphagia.
  • This addresses a critical gap in managing patients undergoing glossectomy.

Purpose of the Study:

  • To develop and validate a risk model for predicting feeding tube dependence after tongue reconstruction.
  • To identify independent risk factors associated with postoperative dysphagia.
  • To provide a quantitative tool for preoperative risk assessment.

Main Methods:

  • Retrospective study of 532 patients with oral tongue squamous cell carcinoma undergoing glossectomy and reconstruction.
  • Data collected from 31 cancer centers in Japan (2009-2013).
  • Univariate and multivariate logistic regression analyses used to identify risk factors and develop a scoring system.

Main Results:

  • 10.2% of patients required a feeding tube postoperatively.
  • Key predictors for feeding tube dependence include advanced age, low BMI, comorbidities, extensive tongue defects, and postoperative radiation.
  • A risk model assigning points to age (≥58.5 years), postoperative radiation, wider tongue defect, and BMI (<21.27 kg/m²) was developed.

Conclusions:

  • The developed risk model offers a mathematical tool for estimating individual risk of feeding tube dependence.
  • This model can aid in preoperative planning and patient counseling.
  • It facilitates personalized management strategies for tongue reconstruction patients.
