[The lymphatic drainage of the esophagus]

Abstract

The study was carried on 65 cadavers: 50 adults and 15 newborns. The esophagus was injected at the level to the neck 16 times, in the thorax at the superior level 18 times, middle level 30 times and inferior level 21 times. The lymphatic pathways were named short when joining the nodes at the same level, half long when joining the nodes of the neighbouring level, long when joining third level, and very long. At the level of the neck were injected 24 lymph nodes chains: in 12.5% of the cases the pathways were long, joining the nodes of the arch of the Azygos vein. At the superior thorax level were injected 27 chains: half of the pathways were half-long: 7.5% long (-joining the pharynx once and the cardia once). At the middle thorax level were injected 37 chains: 27% were long and very long. At the inferior thoracic level were injected 21 chains: The pathways were half long in half cases and very long in 15% of the cases joining the cervical nodes. These results compare with experience in oncology and justify the need for total esophagectomies and nodes resection of all levels in surgical treatment of carcinomas of the esophagus.
