Manometric characteristics in patients with Jackhammer esophagus.
| | | Total n = 36 () |
| | DCI values | | | Mean overall DCI (mmHg.s.cm) | 8 100 | | Mean DCI among DCI > 8000 (mmHg.s.cm) | 11 700 | | Range of hypercontractile DCI (mmHg.s.cm) | 8 000 – 47 760 |
| | 40% hypercontractile contractions | 24 (67) | | 50% hypercontractile contractions | 14 (39) | | 80% hypercontractile contractions | 5 (14) |
| | Basal mean LES pressure | | | Normal (10 – 45 mmHg) | 28 (78) | | Hypertonia ( 45 mmHg) | 8 (22) |
| | LES relaxation | | | Normal median IRP ( 20 mmHg) | 28 (78) | | Elevated median IRP ( 20 mmHg) | 8 (22) |
| | Normal mean residual LES pressure ( 8 mmHg) | 29 (81) | | Elevated mean residual LES pressure ( 8mmHg) | 7 (19) |

DCI: distal contractile integral. LES: lower esophageal sphincter. IRP: integrated relaxation pressure.
