Internal Herniation Incidence After RYGB and the Predictive Ability of a CT Scan as a Diagnostic Tool

1

Internal herniation (IH) is a significant late complication of Roux-en-Y gastric bypass (RYGB) surgery.
2

The use of CT scans for diagnosing IH shows variable sensitivity and specificity, complicating clinical diagnosis.
3

Recent studies indicate that CT scans have a specificity of 87.1% and a negative predictive value of 96.8% in detecting IH.
4

The study compares IH incidence between patients with closed and non-closed mesenteric defects after RYGB.
5

Data were collected from a retrospective cohort of RYGB patients, focusing on the impact of surgical techniques on IH incidence.
