| GEJ | 40 | DMin [mm] | 9.4 (6.9–12) | 13.7 (11.5–18.2) | 11.3 (7.8–15.2) | 1.6 (−1.9–5.1) | 0.401 |
| DI [mm2/mmHg] | 1.4 (1.1–2.6) | 3.8 (1.9–8.9) | 2.9 (2.6–5.3) | 1.6 (−0.5–3.2) | 0.046 | ||
| Pylorus | 40 | DMin [mm] | 13.4 (12.6–16.9) | 13.7 (12.5–17.2) | 16.2 (14.6–17.3) | 1.2 (−1.9–4.4) | 0.401 |

Values are medians (interquartile ranges (IQR)), differences given as mean with 95%CI; significances assessed using Mann-Whitney U comparing pre- and postoperative values.
Abbreviations: ∆, delta or difference; DI, distensiblity index; DMin, minimal diameter; GERD, gastroesophageal reflux disease
