Dynamic esophageal manometry reveals pseudoachalasia secondary to metastatic breast cancer: A case report

Figure 1 High-resolution manometry findings. A: High-resolution manometry (HRM) on September 8, 2016 demonstrated peristaltic waves with a distal contractile integral of less than 450 mmHg.s.cm. A mild increase in intra-bolus pressure was observed after swallowing, with a median 4-seconds integrated relaxation pressure (IRP) of 12.8 mmHg and normal esophagogastric junction (EGJ) pressure; B and C: HRM on January 6, 2017 shows the distal latency of 1/10 waves is less than 4.5 seconds, 9/10 waves show pan-esophageal pressurization. The minimal pressure of the low esophageal sphincter during respiration is 38.2 mmHg, 4 seconds IRP median is 46.9 mmHg, with a significant increase in EGJ pressure.
