Figure 7.
Outcome analysis tree for retention (A) and Eckardt score (B). A breakdown of patients and % based on distensibility index (DI) and anatomy is shown. Statistically significant differences are indicated. Discordant cases are marked with an *.
3/5 cases a low DI yet no retention had repetitive antegrade contractions, and all 5 had contractility. Both cases of deformity were epiphrenic diverticula.
4/5 cases with retention despite a normal DI had a DI < 3.5 suggesting a borderline obstruction. 3/5 of these cases also had repetitive retrograde contractions.
2/2 cases with an ES >3 despite a normal DI had a DI < 3.5 suggesting a borderline obstruction. 1 of these cases also had repetitive retrograde contractions.
