Understanding the Impact of Bowel Dysfunction on Quality of Life After Rectal Cancer Surgery From the Patient’s Perspective
Bibliographic record
Abstract
BACKGROUND: Bowel dysfunction is an important consequence of rectal cancer surgery' and the specific quality-of-life domains that are affected remain unclear and unaddressed by generic surveys. OBJECTIVE: This study aimed to identify quality-of-life domains most affected by rectal cancer surgery. DESIGN: Qualitative content analysis. SETTINGS: Semistructured interviews conducted by telephone with patients recruited from a single university-affiliated colorectal referral center. PATIENTS: Adult patients were included if they underwent rectal cancer surgery with sphincter preservation from July 2017 to July 2020. Patients were excluded if their surgery was <1 year since the recruitment date, received a permanent stoma, or developed recurrence or metastasis. MAIN OUTCOME MEASURES: Bowel dysfunction was evaluated via the low anterior resection syndrome score. Interview transcripts were coded by 2 independent reviewers and evaluated for concordance. Qualitative content analysis was used to identify themes, and their frequency of occurrence was quantified (percent total number of interviews). RESULTS: A total of 54 patient interviews were conducted. Analysis revealed 5 quality-of-life-related themes impacted by bowel dysfunction: experiencing psychological and emotional stress, challenging roles and relationships within society, encountering physical limitations, restricting leisure and recreational activities, and learning self-empowerment and adapting to change. Patients with minor and major bowel dysfunction were more likely to report disruption to their social activities and their role as a sexual partner versus those with no bowel dysfunction. Patients with major bowel dysfunction were more likely to report effects on sleep versus those with no and minor bowel dysfunction. LIMITATIONS: Single center, self-reported, and observer bias. CONCLUSION: The impact of bowel dysfunction on quality of life includes a wide range of themes that extend beyond traditional measures. These results may help better inform patients in the preoperative setting and serve as a basis for the development of a more patient-centered quality-of-life survey. COMPRENDER EL IMPACTO DE LA DISFUNCIN INTESTINAL EN LA CALIDAD DE VIDA DESPUS DE LA CIRUGA DE CNCER DE RECTO DESDE LA PERSPECTIVA DEL PACIENTE: ANTECEDENTES:La disfunción intestinal es una consecuencia importante de la cirugía del cáncer de recto y los dominios específicos de la calidad de vida que se ven afectados siguen sin estar claros y sin abordarse en las encuestas genéricas.OBJETIVO:Identificar los dominios de calidad de vida más afectados por la cirugía del cáncer de recto.DISEÑO:Análisis cualitativo de contenido.ÁMBITOS:Entrevistas semiestructuradas realizadas por teléfono con pacientes reclutados de un único centro de referencia colorrectal afiliado a una universidad.PACIENTES:Pacientes adultos intervenidos de cáncer de recto con preservación de esfínter del 07/2017 al 07/2020. Los pacientes fueron excluidos si su cirugía fue <1 año desde la fecha de reclutamiento, recibieron un estoma permanente o desarrollaron recurrencia o metástasis.PRINCIPALES MEDIDAS DE RESULTADO:La disfunción intestinal se evaluó a través de la puntuación del síndrome de resección anterior baja. Dos revisores independientes codificaron las transcripciones de las entrevistas y evaluaron su concordancia. Se utilizó el análisis de contenido cualitativo para identificar los temas, cuantificando su frecuencia de aparición (porcentaje del número total de entrevistas).RESULTADOS:Se realizaron un total de 54 entrevistas a pacientes. El análisis reveló cinco temas relacionados con la calidad de vida afectados por la disfunción intestinal: experimentar estrés psicológico y emocional, roles y relaciones desafiantes dentro de la sociedad, encontrar limitaciones físicas, restringir actividades recreativas y de ocio, y autoempoderamiento y adaptación al cambio. Los pacientes con disfunción intestinal menor y mayor tenían más probabilidades de informar la interrupción de las actividades sociales y el papel como pareja sexual en comparación con aquellos sin disfunción intestinal. Los pacientes con disfunción intestinal importante tenían más probabilidades de informar efectos sobre el sueño en comparación con aquellos sin disfunción intestinal o con disfunción intestinal menor.LIMITACIONES:Sesgo de un solo centro, autoinformado y observador.CONCLUSIÓN:El impacto de la disfunción intestinal en la calidad de vida incluye una amplia gama de temas que se extienden más allá de las medidas tradicionales. Estos resultados pueden ayudar a informar mejor a los pacientes en el entorno preoperatorio y servir como base para el desarrollo de una encuesta de calidad de vida más centrada en el paciente.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
