Correction of severe postconization cervical stenosis by means of bipolar office hysteroscopy
Bibliographic record
Abstract
espanolObjetivo: describir la utilidad de la histeroscopia en consulta para el tratamiento de la estenosis cervical grave posconizacion. Material y metodos: se trata de un estudio retrospectivo realizado en un hospital terciario. Se analizan 18 pacientes con estenosis cervical grave tras haber sido sometidas a una conizacion por displasia cervical. La tecnica fue realizada por histeroscopia en la consulta. Tras aplicar anestesia local paracervical, el histeroscopio se introducia en el cervix con guia ecografica. Una vez que se alcanzaba la cavidad uterina, el histeroscopio se retiraba hasta colocarlo en el canal endocervical desde donde el electrodo bipolar iba resecando los tejidos cicatriciales y necroticos a lo largo de este canal. Dos meses mas tarde las pacientes eran citadas para realizar una histeroscopia diagnostica de comprobar el paso del canal cervical. Resultados: de las 18 pacientes incluidas en el analisis, en 17 este resulto efectivo en el primer intento (94,4%). La otra paciente necesito una segunda intervencion. El tiempo medio de intervencion fue de 18.0 (SD 67,4) minutos. La histeroscopia de revision fue exitosa en todas las pacientes. Conclusion: la reseccion cervical histeroscopica es un medio seguro y efectivo para tratar la estenosis cervical posconizacion. EnglishObjective: To describe the use of office hysteroscopy as a new tool for the treatment of severe postconization cervical stenosis. Material and methods: Retrospective study (Canadian Task Force classification III) in a Tertiary General Hospital. 18 patients with severe cervical stenosis after cervical conization because of cervical dysplasia. The procedure was performed by means of office hysteroscope. After local anesthesia was administered, the diagnostic hysteroscope was advanced under visual and ultrasonic guidance. Once the uterine cavity was reached, the hysteroscope was withdrawn, and the bipolar electrode resected protrusions and scarring along the endocervical canal. Two months later, patients were scheduled to assess clinical outcome and to repeat hysteroscopy to assess cervical patency. Results: The procedure was successful in 17 of 18 patients (94.4%) in the first trial. The other patient needed a second procedure. The mean operation time was 18.0 (67.4) minutes. Repeat hysteroscopy was successful in all patients. Conclusion: Hysteroscopic cervical resection is a safe and effective treatment for cervical stenosis.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
