[Therapeutic and diagnostic problems in a patient with insulinoma (author's transl)].

Surgical intervention in organic hyperinsulinism is based on prior accurate biochemical assessment. The emergent problems are discussed in a case with hypoglycaemic attacks, where "blind" pancreatic resections had been performed in two occasions without success. Finally, after demonstration of hyperinsulinaemia and localization of the tumour by selective angiography an adenoma was removed surgically. The postoperative complications, including the development of insulin-dependent diabetes, demonstrate the inherent risks of blind distal pancreatectomy for suspected insulinoma.

[Long-term results after isolated aortic and mitral valve replacement with a prosthesis (author's transl)].

111 patients with aortic valve replacement (AVR) and 159 patients with mitral valve replacement (MVR) were studied after hospital discharge. The late mortality was 20% after AVR and 32% after MVR. Of the survivors, 93% were greatly improved after AVR and 83% after MVR (functional class I or II). The calculated 5-year survival rate of the patients with AVR is 76% and with MVR 64%. The general state of health of the survivors, the thromboembolic rate and the fatal complications are discussed. Further improvement in the results can only be expected if valve replacement is performed before irreversible myocardial damage has occurred.

[Cystic changes in the lungs in childhood (author's transl)].

Two boys with presumably congenital cystic changes in the lungs are described. In one child multiple cystic deformations led to acute symptoms of severe respiratory distress necessitating urgent resection of the right middle and upper lobes. The other boy had a large thick-walled cyst in the left upper lobe causing no distress whatsoever. This patient was observed for more than 6 years before operation. Multiple vascular anomalies and anastomoses were revealed during surgery. Both cases are presented in detail and the completely different clinical course is outlined. Only when careful supervision of intrapulmonary cystic changes is guaranteed can operation be postponed for longer than 6 months. Pulmonary cysts may lead to emergency procedures. They are always a potential source of serious complications such as rupture or infection. When no tendency for regression can be discovered surgical removal is indicated. Conservative treatment will not influence the course. Differential diagnosis is discussed briefly.

[Clinical picture and therapy of gastroschisis (author's transl)].

The results of operative treatment of gastroschisis have been improving in recent years. The survival rate is now between 50 and 60 p.c. It is very important to perform primary repair as soon as possible after birth. According to our own experiences resection of the bowel should be avoided as it gives a poor prognosis. Combined malformations of gastroschisis are very rare and their treatment should be tired since there is no other alternative. An own successfully treated case of combined malformations of gastroschisis with atresia of the small bowel is presented. Stenosis of the duodenum and tubular duplication are described
