[Esophageal dilatation using the Savary-Gilliard sound set]. / Nyelöcsötágítás Savary--Gilliard-szondasorozattal.

Authors present a method of esophageal dilatation and report their experiences. The place of esophageal dilatation among other therapeutic approaches of esophageal stricture is discussed. The advantage of Savary-Gilliard bougies and guide wire and its applications are presented. During one and a half year 218 esophageal dilatations were performed at 82 patients. 11 patients were intubated endoscopically. Esophageal perforation occurred in 2 cases (0.93%). Dilatation of the esophagus with Savary-Gilliard bougies and using of the guide wire are considered a safe and many-sided method in the diagnosis and treatment of esophageal strictures.

[Can gastroesophageal reflux be prevented by inducing a scar tissue ring around the cardia?]. / Megakadályozza-e a gastrooesophagealis refluxot a cardia körül kialakított heges gyürü?

Severe gastroesophageal reflux was accomplished in 18 dogs by circular cardiomyectomy. After this intervention a Vicryl scarf was placed around the cardia in 12 dogs. The Vicryl scarf was absorbed within 6 months and in its place remained a scarred tissue. In the follow up gastroesophageal reflux could not be detected by manometry, pH-metry, radiology and endoscopy. In the control group all 6 dogs died within 3 weeks due to complications of gastroesophageal reflux. On the basis of these data the Vicryl scarf implantation is an effective, simple, new antireflux operation which can be initiated into the human surgical practice.

[Reconstruction of the oral and pharyngeal mucosa by a microsurgical method using a jejunal graft]. / Szájüregi és garatnyálkahártya pótlás mikrosebészeti módszerrel átültetett vékonybéllel.

The microsurgery is a new, modern method of the reconstructive surgery which has made the free transplantation of the jejunal graft possible. The jejunum transplanted with microvascular anastomosis lends itself mainly to replacing the segmental and concentrical defect of the initial part of the alimentary tract, but the splitted jejunal graft cut along the antimesenterical side, because of its favourable biological nature, can be used for reconstruction of the oral and pharyngeal mucosus membrane. The authors applied the splitted jejunal graft in four cases for the reconstruction of oropharyngeal defects due to excision of malignant tumours. In harmony with literary data good result is reported on.

[Management of injuries of the artificial esophagus]. / Arteficiális nyelöcsö sérülések ellátása.

The authors analyse their experiences in connection with 20 cases of artificial esophageal injuries. Attention is called to the intraoperative lesions of the esophageal wall and to the damages caused by drugs. They underline the importance of the time factor and good results were achieved by using so called "conservative surgical treatment".
