[Ectopic pancreas in the duodenum].

Aberrant pancreas to the duodenal site is a by no means simple problem of diagnosis as it is only rarely that X-ray, gastroscopy or biopsy suggest it. The case of aberrant pancreas in the duodenum, simulating a peptic lesion, is reported. Following an anatomo-pathological study, the typical aspects of the case are stressed.

[Carcinomas of the small intestine].

Two cases of carcinoma of the small intestine are described. In spite of its large epithelial surface, this organ is rarely a cancer site. For these reason, an account is given of cases observed over the previous year. In addition, mention is made of the pathological anatomy, symptomatology, preoperative investigation, and treatment of this form.

[Transduodenal papillosphincteroplasty].

On the basis of a thourough anatomosurgical study of Vater's ampulla and after a critical survey of all surgical techniques for the sphincter of Oddi, the indications for and technique of total papillosphincteroplasty are presented. The results obtained in 544 total papillosphincteroplasties, their possible complications and failure supported by long-term (from 6 months to 7 years) follow-up are discussed. The conclusion is drawn that papillosphincteroplasty is to be considered the surgical technique of choice in the treatment of benign pathology of the main bile way.

Results of surgical resection of stage IIIa (N2) non small cell lung cancer, according to the site of the mediastinal metastases.

Out of a series of 1563 consecutive patients submitted to thoracotomy for lung cancer between 1980 and 1990, 278 patients underwent a resection for a non small cell lung cancer (NSCLC) with mediastinal node metastases (N2). Selection of cases for surgery was carried out using CT from 1983 and mediastinoscopy for the patients with mediastinal lymph nodes larger than 1.5 cm from 1985: all patients with positive mediastinoscopy were excluded from thoracotomy, but 10 cases underwent a resection after neoadjuvant radio-chemotherapy. The surgical procedures were pneumonectomy (106), lobectomy (146) and atypical resection (8) with ipsilateral mediastinal lymphadenectomy. Resection was complete in 236 patients (84.8%) and incomplete in 42 patients (15.2%). Postoperative mortality was 3.2%. Almost all patients received radiotherapy after surgery. Actuarial 5-year survival was 13.7% for the entire group and 18.5% for the patients who underwent curative resection; no patients survived 5 years after palliative resection (p < 0.05). There were no differences with regard to prognosis according to the histology of the tumors and to surgical procedures. A better prognosis is associated with: completeness of resection, involvement of only one level, low T classification. Five-year survival rate of patients with metastases only in upper mediastinum was 25%; on the contrary 5-year survival rate of patients with metastases in the lymph nodes of the lower mediastinum was only 8% (p < 0.05). In our opinion better results among the patients with metastases in the upper mediastinum depends on the selection obtained with mediastinoscopy.(ABSTRACT TRUNCATED AT 250 WORDS)

[Cholecystosis].

Cholecystosis conditions include those diseases of the gallbladder whose aetiopathogenesis is to be sought in a hyperplasia of the tissues making up the cholecystic wall (hyperplastic forms) and in an overload of this wall on the part of organic substances or minerals such as lipides or calcium salts (thesaurismosic forms). After discussing the classification, pathological anatomy, aetiopathogenesis, frequency, symptomatology, laboratory and radiological examinations, prognosis complications and treatment of these conditions, a personal series of 36 surgically treated cholecystoses is reported.

[Spontaneous and traumatic pneumomediastinum. Analysis of 34 cases].

Pneumomediastinum (spontaneous, iatrogenic and traumatic) is a relatively uncommon infrequently reported entity. The most common cause is the rupture of marginal pulmonary alveoli, allowing bubbles of air to dissect along the vascular sheaths and connective tissue planes to the mediastinum. Rupture of the trachea or thoracic traumas are other causes of pneumomediastinum. The most common presenting complaint was retrosternal pain, dyspnea, dysphagia, weakness and neck pain. Physical finding revealed: subcutaneous emphysema extended to face, chest or neck, and Hamman's sign. Chest X-ray was made in all cases and diagnosis was completed with chest CT scan and tracheoscopy. We present our series of 34 PM between January 1.1993 to July 31.1995 and discuss about etiology, diagnosis and treatment of this entity.
