[Gastrointestinal carcinoids and carcinoid syndrome: classification, diagnosis and therapy].

Historically, carcinoids have long been known as a morphologically distinct class of rare intestinal tumors which behave less aggressively than the more common intestinal adenocarcinomas. In recent decades refined methods in pathology improved our knowledge on the diffuse neuroendocrine system, leading to some confusion in classification and nomenclature of carcinoids. The World Health Organization (WHO) classification of endocrine tumors has cleared the definition of carcinoids. The Authors report on 7 cases of midgut carcinoid tumors and 1 case of carcinoid syndrome focusing on the newer approaches to the diagnosis, localization, and role of surgery and peptide therapy.

[Surgery of differentiated cancer of the thyroid].

A retrospective study on patients with differentiated thyroid carcinoma operated on at the 3rd Department of General Surgery of the University "La Sapienza" of Rome from 1970 to 1996 was performed. In 709 patients total thyroidectomy was performed as the minimal procedure acceptable, while 19 patients had subtotal thyroidectomy out of necessity. A functional ipsilateral or bilateral lymphnectomy of the neck was performed in 256 cases. This wider operation is indicated in the presence of metastatic lymph nodes and on principle in patients older than forty-five years in which at least another risk factor is present. Long term follow-up (12 years) was assured in 302 patients and the survival rate was 92% independently from the histotype (papillary or follicular). The survival rate of a group of 120 patients (80 with papillary and 40 with follicular carcinoma) was analyzed in relation to the risk factors. This group analysis demonstrated a very low mortality rate in patients with low risk index and an increased rate in patients with a high risk index.

[Artificial nutrition in acute pancreatitis].

Nutritional support for acute pancreatitis is a matter of debate, clear guidelines based on objective data do not exist. We report our experience in patients with severe disease. Parenteral nutrition appears to be a safe initial therapy, but the enteral route has many practical and theoretical advantages and should be started as soon as possible.

[PTFEe in the treatment of facial wrinkles].

The first signs of skin aging appear quite early, around 30 years of age, and show as glabella and facial wrinkles particularly pronounced around the eye, lips and nasolabial area. None of these imperfections can be expressively modified through a cervicofacial rhytidectomy (facelift). The use of PTFEe in reconstructive surgery has been established by years of positive experience; therefore, the well known characteristics of such material suggested the idea of extending its use to aesthetic surgery. The corrections performed with this material are carried out mostly as day hospital surgery in local anaesthesia, requiring, however, technical skill to obtain satisfying results.

[Malignant fibrous histiocytoma of the pancreas].

The authors report a case of pancreatic malignant fibrous histiocytoma (approximately 22 cm). Clinical and instrumental approach for preoperative diagnosis is discussed and the anatomopathological features of the lesion, which is rarely localized in the pancreatic gland, are stressed. Surgical treatment is outlined as well.

[Report on surgical strategy in reoperation of esophageal achalasia].

Surgical therapy for achalasia of the esophagus gives good results in only 80-90% of cases. Several reasons could be responsible for this 10-20% failure; the most frequent causes are inadequate cardiomyotomy and reflux esophagitis. We report our experience and our procedure in the management of recurrent achalasia. The most important controversies are also discussed.

[Direct post-mastectomy reconstruction with skin expansion. Technical notes].

The demolition-reconstruction sequence in patients suffering from breast cancer may, in selected cases, be reduced to two surgical steps alone without compromising the radical nature of the surgery or the aesthetic result. The technical details of a protocol realisable in a short time that proposes on the one hand classical radical mastectomy (according to Patey or Madden) and on the other reconstruction by tissue expansion are described.

[Early postoperative enteral nutrition and total parenteral nutrition. Technics compared in patients undergoing radical surgery for carcinoma of the large intestine. Preliminary report].

A preliminary study has been carried out on 10 patients suffering from cancer of the colon and rectum, all subjected to radical surgery. The clinical effectiveness of two alternative techniques of postoperative artificial nutrition, EPEN and TPN, are compared. The results confirm that enteral nutrition is technically applicable and well tolerated in the immediate post-operative period in these patients; it also presents a lower cost, it is more manageable and present a lower incidence of complications compared to TPN while offering similar metabolic and nutritional results.

[Low-malignancy duodenal leiomyosarcoma].

The authors report a case of duodenal leiomyosarcoma presenting a low degree of histological malignancy. The main anatomoclinical features of the neoplasm are summarized. The authors conclude indicating not aggressive surgical therapy as adequate in such cases. However, a prolonged post-operative follow-up is always necessary, in order to detect recurrences as early as possible.

[Liposuction treatment for lipodystrophy of the pelvis and the legs].

In a series of 20 lipolysis procedures, there have been no serious major and few minor complications. Selection of patients is important and the best results can be acquired in the patients under 35 years of age. The postoperative circulation and diuresis control are very important particularly during the first 24 hours.

[Cavernous hemangioma of the small intestine].

The Authors report an uncommon cavernous hemangioma of the small bowel. Pathological and clinical features are compared with those of the literature. Considering the difficulty of diagnosis, they remark the importance of histological exam as the only reliable diagnostic tool and surgery as the only therapy.
