[Report on a case of schwannoma of the neck: clinical and therapeutic considerations]. / A proposito di un caso di schwannoma del collo: considerazioni clinico-terapeutiche.

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. The tumour arose from the cervical sympathetic chain. The diagnosis of schwannoma was possible only at histopathological examination. After 24 months no local recurrence or postoperative complications related to the intervention were found. At present, however, the patient presents a moderate lowering of the voice, such as may be due to impairment of the superior laryngeal nerve, though this was already present preoperatively. These lesions are uncommon and most often occur as asymptomatic solitary neck masses. The preoperative diagnosis may be difficult, even with the aid of ultrasound, computed tomography, magnetic resonance imaging, and angiography. Identification of the nerve is often difficult up to the time of surgery, which is the treatment of choice for schwannoma.

[Treatment of acute biliary pancreatitis: our experience]. / Trattamento della pancreatite acuta biliare. Nostra esperienza.

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). Endoscopic sphincterotomy was performed in 18 patients with stones in the common bile duct and was successful in 94.5% (17 patients: 3 patients underwent more than one session to confirm or achieve clearance of the duct). The morbidity rate associated with endoscopic sphincterotomy was 16% (3 patients: 2 haemorrhages, 1 perforation). There were no deaths. Cholecystectomy was performed in 16 patients within 2-9 weeks of the initial attack of acute biliary pancreatitis. There were 3 minor complications (respiratory, laparotomy, urinary infection), no major intraoperative or postoperative morbidity, and no mortality. Acute biliary pancreatitis is still associated with significant morbidity and mortality, but can be managed safely with combined medical, endoscopic and surgical treatment.
