NCT04311333

Brief Summary

The intention is to examine the role of ultrasonographic examination inside intestinal stomas in diagnosing parastomal hernia. Patients with a stoma since at least one year back who are being scheduled for abdominal surgery will be examined for eligibility according to the selection criteria. Included patients will undergo routine clinical examination, endostomal ultrasonography and computerized tomography scan of the abdomen. Findings will be correlated to findings during surgery (gold standard). Values for sensitivity, specificity, predictive values and likelihood ratio will be calculated.

Outcome Measures

Primary Outcomes (1)

  • Test characteristics

    Sensitivity, specificity, predictive values, likelihood ratio

    ≥ 1 year since stoma creation

Study Arms (1)

All patients

EXPERIMENTAL

All patients undergo endostomal three-dimensional ultrasonography, computerized tomography, clinical examination and laparotomy/laparoscopy. At all the respective examinations, the presence of a parastomal hernia as well as hernia location and size is evaluated.

Diagnostic Test: Endostomal three-dimensional ultrasonographyDiagnostic Test: Computerized tomography of the abdomenDiagnostic Test: Clinical examinationDiagnostic Test: Evaluation at laparotomy/laparoscopy

Interventions

Examination with rectal probe enclosed by water-filled balloon. Rectal mode. Dynamic examination in different positions with and without increased intra-abdominal pressure.

All patients

Supine position, without increased intra-abdominal pressure. Experienced radiologist interprets the examination. If adequate examination has already been performed within the last 10 months, these images will be used and the patient will thus not undergo computerized tomography within the study.

All patients
Clinical examinationDIAGNOSTIC_TEST

Patients will be clinically examined with inspection and palpation in supine and erect position with and without increased intra-abdominal pressure.

All patients

During laparotomy or laparoscopy, inspection and/or palpation of the stoma at the abdominal wall orifice is performed.

All patients
