Risk Factors for Pharyngocutaneous Fistula After Laryngectomy, 2000-2021

17.5% of 160 laryngeal cancer patients developed a pharyngocutaneous fistula after total laryngectomy. This dataset contains medical records from Karolinska University Hospital, analyzed to identify associated risk factors using uni- and multivariate methods. The data was authored by Petronella Pettersson and last updated in June 2026.

Use Cases

• Predicting fistula risk based on patient comorbidities and preoperative hemoglobin levels mentioned in the description
• Analyzing the impact of prior radiotherapy and surgical procedures like pharyngectomy on postoperative outcomes
• Building models to assess the independent risk contribution of postoperative infection and pectoral flap reconstruction

Strengths

• Contains data from 160 patient records spanning a 21-year period (2000-2021).
• Analysis includes specific odds ratios for eight significant risk factors identified in univariate analysis.
• Dataset is licensed under CC-BY-4.0, allowing for open sharing and adaptation.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single hospital, which may reflect geographic or institutional bias.
