4.1 Major findings
This present study has relevant clinical implications, summarized as the
main findings, as follows: 1) There was a long distance from the MPL to
the esophagus, compared with the distance from the CPL to the esophagus.
2) The myocardium and fat pad in the course of MPL was thicker than in
the course of CPL; 3) A higher presence of fat pad was noted between the
MPL and the esophagus than between CPL and esophagus 4) The MPL was
observed to have a longer distance to the esophagus, thicker myocardium,
and higher presence of fat pad in each type of esophageal route below
the CPL than the CPL. 5) The average distance from MPL to the esophagus
in patients with unconfined esophagus in the triangular space at the
left inferior PV level was longer than those with confined esophagus in
the triangular space at left inferior PV level. Nonetheless, the average
distance from the MPL to the esophagus, compared with the CPL was still
longer to the esophagus in the confined group.
