[Report on a case of schwannoma of the neck: clinical and therapeutic considerations].

We present a case of schwannoma of the neck in 49-year-old man, which was symptomatic for a long period: paraesthesia for one year, cervical mass for 2-3 months and dysphagia during the last 20 days. After ultrasonography and magnetic resonance the patient was operated on and complete excision of the mass was performed. The operation was performed via a cervical approach: the nerves and vascular and muscular structures were carefully isolated and then preserved.

[Treatment of acute biliary pancreatitis: our experience].

The results of endoscopic and surgical treatment in 21 patients affected by acute biliary pancreatitis are reported. All patients were managed according to the same protocol. Once the diagnosis was formulated (pain, serum amylase, ultrasonography, cholestasis and/or cholangitis) and the severity evaluated (Ranson's criteria, glucose and urea levels), the 21 patients underwent endoscopic retrograde cholangiopanctratography--within 24 hours in 8 patients (predicted severe disease) or within 72 hours in 13 patients (predicted mild disease).
