Article Synopsis
  • Peroral endoscopic myotomy (POEM) is a procedure for treating esophageal motility disorders, but its effects on high-resolution manometry (HRM) findings and post-POEM outcomes are not fully understood.
  • In a study of 2,171 patients with achalasia, 7% had significant residual high integrated relaxation pressure (IRP) after POEM, with high pre-procedure IRP being a strong predictor of this outcome.
  • Findings suggest that while extended gastric myotomy can reduce IRP values, the recovery of peristalsis is more related to the type of achalasia rather than the length of the myotomy, indicating that high post-POEM IRP does not equ

Gastric cancer (GC) ranks fifth in global cancer diagnosis and fourth in cancer-related death. Despite tremendous progress in diagnosis and therapeutic strategies and significant improvements in patient survival, the low malignancy stage is relatively asymptomatic and many GC cases are diagnosed at advanced stages, which leads to unsatisfactory prognosis and high recurrence rates. With the recent advances in genome analysis, biomarkers have been identified that have clinical importance for GC diagnosis, treatment, and prognosis.
