BACKGROUND: A challenge in esophageal reconstruction after esophagectomy is that the distance from the neck to the abdomen must be replaced with a long segment obtained from the gastrointestinal tract. The success or failure of the reconstruction depends on the blood flow to the reconstructed organ and the tension on the anastomotic site, both of which depend on the reconstruction distance. There are three possible esophageal reconstruction routes: posterior mediastinal, retrosternal, and subcutaneous. However, there is still no consensus as to which route is the shortest.
METHODS: The length of each reconstruction route was retrospectively compared using measurements obtained during surgery, where the strategy was to pull up the gastric conduit through the shortest route. The proximal reference point was defined as the left inferior border of the cricoid cartilage and the distal reference point was defined as the superior border of the duodenum arising from the head of the pancreas.
RESULTS: This study involved 112 Japanese patients with esophageal cancer (102 men, 10 women). The mean distances of the posterior mediastinal, retrosternal, and subcutaneous routes were 34.7 ± 2.37 cm, 32.4 ± 2.24 cm, and 36.3 ± 2.27 cm, respectively. The retrosternal route was significantly shorter than the other two routes (both p < 0.0001) and shorter by 2.31 cm on average than the posterior mediastinal route. The retrosternal route was longer than the posterior mediastinal route in only 5 patients, with a difference of less than 1 cm.
CONCLUSION: The retrosternal route was the shortest for esophageal reconstruction in living Japanese patients.
