Resumo
Short esophagus is defined as the inability to reduce the gastroesophageal junction below the diaphragm. One of the factors responsible for this inability can be inadequate esophageal mobilization. We evaluated esophageal lengthening achieved by means of dissection in a cadaveric model. Fifty-one cadavers were dissected (27 transthoracically and 24 transhiatally). Abdominal esophageal length was assessed before and after dissection of the esophagus from the hiatus to the carina. in the transthoracic group, a mean of 1.7 +/- 1.3 cm (range 0.3 to 5.0 cm) was gained with dissection. in the transhiatal group, a mean of 1.8 +/- 0.8 cm (range 0 to 3.0 cm) was gained with dissection. in a comparison of results of transthoracic and transhiatal approaches, the difference was not statistically significant. We concluded that a significant increase in esophageal length was achieved after dissection;, however, the access route (thorax or abdomen) did not influence the results.
