Pancreatic insulinomas.

We report a series of 30 patients with pancreatic insulinoma treated from 1967 to 1990. Twenty-nine patients underwent surgery. In 24 patients, the lesion was a benign adenoma. The pancreatic lesion was localized preoperatively in 59% of cases (94% since 1980), and all lesions that were identifiable histologically were palpable intraoperatively. Endoscopic pancreatic ultrasonography, performed twice, appeared to be a very promising method of investigation. In the 24 patients with adenoma, 14 enucleations and 10 pancreatic resections were performed, with the enucleation rate increasing over time. One patient died during the postoperative period. Pancreatic fistulas (43%) were the most common cause of morbidity and were more common after enucleation (57% versus 29% after pancreatectomy). The mean follow-up period was 7 years. Excluding the patients with adenocarcinomas, the recovery rate was 92% (23 of 25 among whom 2 patients had transitory recurrent hypoglycemia), 2 patients who underwent corporeo-caudal pancreatectomy being diabetic (8%).

[Trauma emergency care].

The organization of trauma care within the country is essential. Hospitals able to provide optimal care for the injured patient must be selected. Every hospital have to evaluate its capabilities and resources and its places in the emergency medical services system. The number of hospitals defined to take care of severely injured patient should be defined by many factors: geography and population density, capable personnel immediately available priority of access to sophisticated laboratory and radiologic services, operative rooms and intensive care units. University Hospitals should have a trauma service connected with the department of surgery to take care of severely injured patients. General hospitals are an important resource to take care of others trauma patients.

[Cystadenoma and cystadenocarcinoma of the pancreas. Apropos of 7 new cases].

Cystadenomas and cystadenocarcinomas of the pancreas are tumours which remain poorly known because of their relative rarity. They are seen essentially in women aged between 40 and 60 and involve the left half of the pancreas more often than the right. The symptomatology remains latent for a fairly long time, which explains the fact that they are most often discovered only at the stage of a palpable tumour. Recent methods of investigation--echotomography and computed tomography--are of very great value in preoperative diagnosis. It is extremely important to draw the distinction within the group of benign cystadenomas between microcystic forms and macrocystic forms or mucinous cystadenomas, the latter having a definite potential for malignant change, possibly explaining the link with certain cystadenocarcinomas. As a result, excision surgery is always preferable, when possible, to bypass surgery, at least in caudal or corporeo-caudal lesions, since excision surgery is usually easy. For cephalic lesions, if excision surgery seems difficult, it may be conceivable, using modern techniques of investigation, to adopt a conservative attitude when there are no features suggestive of potential malignant change.
