<p>Cohort characteristics.</p>

160 patient records from Karolinska University Hospital were analyzed to determine the prevalence and risk factors for pharyngocutaneous fistula following total laryngectomy. The dataset includes demographics, comorbidities, tumor characteristics, treatments, and postoperative outcomes. It was created by Petronella Pettersson and last updated in June 2026.

Use Cases

• Predicting the risk of pharyngocutaneous fistula based on patient comorbidities and treatment history mentioned in the description.
• Identifying independent risk factors for surgical complications using the univariate and multivariate analysis results provided.
• Training models to stratify patient risk using variables like preoperative hemoglobin levels and prior radiotherapy.
• Benchmarking complication rates (17.5% fistula prevalence) against other surgical cohorts.

Strengths

• Dataset is based on 160 patient records from a single institution, providing a focused clinical cohort.
• Analysis includes specific, statistically significant risk factors with odds ratios and confidence intervals (e.g., postoperative infection OR 24.94).
• Clear temporal coverage from 2000 to 2021.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data reflects a single hospital's patient population, which may limit generalizability.
