[Severe obliteration of the urethral lumen after wall stent implantation. An unusual radiographic finding]. / Schwere Obliteration des Harnröhrenlumens nach Wall-Stent-Implantation. Eine ungewöhnliche radiographische Besonderheit.

The treatment of urethral stricture is still a challenge for urologists. Irrespective of the treatment employed, urethral stricture recurs in about 30% of all cases. In recent years, the wall stent, originally conceived for vascular surgery, has proved to be effective for the treatment of bulbar urethral strictures. The results are good, morbidity and complications occur only occasionally. In this paper, we described the case of a young patient who suffered from complete occlusion of the prosthesis 8 months after its implantation. The low age of the patient and the X-ray features of this case are unusual. The obstruction was successfully resolved by endoscopic resection. Follow-up after 14 months revealed a mild, short stenosis of the proximal tip.

[Digital dacryography after insertion of silicone probes after interruption of the lacrimal ducts in childhood]. / Digitale Dakryography nach Einführung von Silikonsonden nach Unterbrechung der Tränengänge im Kindesalter.

Digital dacryography with image subtraction permits a very detailed visualization of the lacrimal pathway, evaluating long-term results of emergency surgery on resected lacrimal canaliculi with silicon probe in children. 65 pediatric patients with traumatic injuries of the eyelid have been treated in emergency surgery with introduction of a silicon catheter. 28/65 patients presented in follow-up the symptom of the "wet-eye": 13 of these patients have been examined with digital dacryography. The examination has permitted exclusion of an organic stenosis or a post-surgical complication of the reconstructed tear duct. The results suggest that the symptom of the "wet-eye" may be explained by a loss of the suction mechanism of the lacrimal papilla.

[Dacryocystography in digital subtraction technique]. / Dakryozystographie in digitaler Subtraktionstechnik.

The authors emphasize the usefulness of dacryography to approach patients affected by epiphora. Digital dacryocystography had improved the anatomic and functional assessment of lacrimal apparatus. The methodology allowed in all patients an accurate visualization of the lacrimal system and the identification, in twenty cases, of pathological causes of epiphora. One patient was examined after dacryocystorinostomy. Digital dacryocystography is a very valuable technique for better contrast resolution, the subtraction of images, and continuous acquisition.

[Incomplete Boerhaave syndrome of the cervical esophagus]. / Inkomplettes Boerhaave-Syndrom der zervikalen Speiseröhre.

It is known that an acute postemetic injury may evoke a spontaneous rupture of the oesophagus. This spontaneous rupture may produce an intramural hematoma or a laceration of the oesophagus wall. The intramural hematoma is restricted to the esophageal wall and may produce a fistula into the lumen of the oesophagus (with creation of a double lumen) or into the mediastinum (haematoma of the mediastinum). On the other hand the rupture may extend from the mucosa (lesion of Mallory-Weiss) into the complete wall of the oesophagus (Boerhaave's Syndrome). There are reports on a lesion of the exterior muscular layer of the third distal half of the oesophagus, which had evoked an acute haemorrhage into the mediastinum and has been defined as a variant of Boerhaave's syndrome. We now describe a similar case which is confined to the cervical oesophagus and has been treated without surgical intervention.
