[Roentgen examination after oesophageal surgery (author's transl)].

Sutureinsufficiency has to be sought postoperatively. Later, tumors, passage disturbances and reflux must be looked for. Antirefluxsurgery with fundoplication may lead to a roentgenmorphology with tumoraspect. After transoesophageal sclerosis of varices passage disturbances and perforations may be seen. After perforations by endoscopic procedures the oesophageal roentgen examination with water-soluble substances completes the clinical surveillance.
