[Postoperative esophageal-visceral fistulae: their prevention and treatment].

A series of 12 cases of esophageal anastomotic leakage following esophageal surgery observed from 1969 to 1989 is retrospectively analyzed. In the period 1969-1975 6 patients were treated in emergency and the mortality rate was 66.6%, while the remaining 6 patients observed from 1975 to 1989 were treated conservatively with total parenteral nutrition (sometimes associating adequate surgical drainage): the mortality rate was 16.6%. In conclusion, not only in the treatment of anastomotic leakage, but also in its prevention, artificial nutrition has a crucial role. The outcome of thoracic and abdominal fistulas depends mainly on adequate drainage, not necessarily surgical. Cervical fistulas heal in 2-4 weeks, but strictures arise frequently and respond to endoscopic dilatation.
