[US or CT-guided percutaneous drainage of pancreatic pseudocyst].

Authors, after illustrating the pathogenesis of Pancreatic Pseudocysts (PPC) and classifying them into secondary to acute pancreatitis and arising in course of chronic pancreatitis, underline that the use of Ultrasound (US), CT-scan, Magnetic Resonance, Endoscopic Retrograde CholangioPancreatography and, above all, percutaneous drainage of the cysts has modified the therapeutic approach to this pathology. They describe indications and technique of US or CT-guided percutaneous drainage, and report their experience about 12 cases of PPC secondary to acute pancreatitis and 4 of PPC arising during chronic pancreatitis. They analyze the limits of this technique (risk of infections, recurrences, fistulas), and conclude that Percutaneous Drainage of Pancreatic Pseudocysts is a useful therapeutic approach in the treatment of PPC secondary to acute pancreatitis, while its use is complementary to surgery in the treatment of PPC due to chronic pancreatitis.

[Nuclear risk and thyroid neoplasms in infancy].

Thyroid carcinoma is a disease with low incidence in adult and rare in child. The authors give oncogenic risk factors of the disease and underline environment factors as iodine deficiency and radiation pollution that, as shown in certain world areas, has a strong effect in the epidemiology of this disease. Eventually radiation's are the most important oncogenic risk factors but and adequate iodine prophylactic program can be considered a valid shield to prevent this disease.

[Principles of rehabilitation of patients with ileostomy].

Authors, believing that ileostomy is the cause of serious clinical, functional and psychological consequences, dwell upon principles of rehabilitation, which aim is the reinstatement of ileostomized patients into daily life. The most important aspect is to select the position of the stoma; it is necessary to consider some technical and functional aspects. The Authors examine local problems of the stoma, the unstable electrolytical balance, and report some therapeutical aspects. They expose early and late complications after surgical therapy and conclude underlining the advantages of a rapid social reinstatement of patients with an ileostomy.

[Alpha-glucosidase and alanine-amino-peptidase in the early diagnosis of renal failure in obstructive jaundice].

Renal failure is a serious complication of obstructive jaundice. Early diagnosis and prevention of spontaneous evolution of the disease can improve prognosis, otherwise very poor in many cases. The Authors, on the basis of experimental researches from literature, expose their clinical experience about the validity of the determination of Alpha-Glucosidase and Alanine-Amino-Peptidase for early diagnosis and differentiation between organic or functional forms of renal failure. They conclude that determination of urinary levels of AGS and AAP is a valid aid for the evaluation of renal function in patients with obstructive jaundice.

[Changes in serum levels of folic acid after total gastrectomy].

The Authors, in consideration that Folic Acid is assimilated in the upper alimentary tract, effected a comparative study between its seric levels in normal patients and in patients submitted to gastrectomy for gastric cancer, at different times from the operation. In the patients of the first group, Folic Acid levels were not correlated with sex, but to age, decreasing with the increasing of it. In gastrectomized patients, serum levels, also if acceptable, were always lower than in control cases, and gradually decreasing with the increasing of the age. The Authors conclude that, obviously, intestinal assimilation and endogenous reserves are able to counterbalance for enough long time the insufficient alimentary absorption.

[Primary adenocarcinoma of the duodenum].

Adenocarcinoma of the duodenum represents a rare neoplasia characterized by an indefinite symptomatology, at least early, and deceitful, that, therefore, arrives at surgeon, almost always, in advanced stage. The Authors, taking from a clinical case, recently observed, as a starting point, review the literature, referring the etiopathogenetic hypothesis that explain the relative rarity of this neoplasia. They therefore report the diagnostic and therapeutic procedure to carry out in these patients.

[Ambulatory treatment of inguinal hernia].

The Authors report their experience about the inguinal hernioplasty operation by implantation of prostheses in prolene following the Licthenstein technique. Prolene mesh strengthens the inguinal canal wall, with no suture tension point. The technique is performed under local anesthesia, in day-hospital system, consenting the patient a rapid reinstatement in the social-working ambit.

[Hemangiopericytoma: diagnostic-therapeutic considerations].

The Authors report a clinical case of hemangiopericytoma recently observed. The biological behaviour of this tumour presents a character of unforeseeableness and, in every chance, needs a long period of follow-up. Based on literature data, the Authors report some diagnostic-therapeutic precise information and underline the scanty reliability of the prognostic factors.

[Gastric precancerous conditions].

The Authors examine the anatomopathological and clinical features of the main gastric precancerouses and explain the diagnostic therapeutic protocols used. The diagnostic and therapeutic strategy can not leave a strict interdisciplinary collaboration out of consideration between radiologist, endoscopist, anatomist, gastroenterologist and surgeon. They conclude, in fact, affirming that the mentioned collaboration represents the one possibility for improving the results at distance of this neoplasia.

[Compression suturing devices in surgery of lateral colostomies].

The Authors refer their experience about two cases of colo-colic anastomosis executed by employment of biofragmentable ring BAR (Valtrac). The Authors used, for the bowel fragments preparation, the ASP-50 rake, overcoming the frequent inconvenient of mucosa extroversion thanks to circumferential mucosectomy extensive for a few mm. of colic fragments. Based on BAR (Valtrac) behaviour and the obtained results, in accord with the most other Authors, they conclude affirming that the compression anastomosis represents a simple methodology, sure and reliable for closing of the lateral colostomies.

[Tumor markers in malignant anorectal pathology].

The Authors note the limits and the more rational directions of using the several tumour markers that they utilized in the study of the neoplastic pathology of the anus-rectum. They particularly point out the benefit as "dynamic indices" of variation of the tumor mass during the neoplasm's progress and treatment. For these neoplasies any new marker offers advantages of diagnostic accuracy and a greater specificity more CEA. Nevertheless other markers used appear interesting as biochemical parameters for tumour growth. The study and the tumour marker's development supported, in recent years, the introduction of new diagnostic methods that include the utilization of monoclonal localization of the tumour mass.

Pre and intra-operative methods of staging gastric cancer.

The aim of this paper was to examine the indications and limits of pre- and intra-operative instrumental diagnosis of gastric cancer. In order to achieve this effectively, the authors emphasized the importance of proper staging methods and obtained a detailed description of tumor diffusion. The most important diagnostic instruments considered were magnetic resonance, endosonography, intra-operative echography, pre- and intra-operative immunoscintography and a cytological examination of peritoneal lavage fluid. The authors concluded that pre- and intra-operative staging of gastric cancer is important for two major reasons: it results in the most accurate definition possible of disease evolution, enabling a proper therapeutic program; and it involves a combination of three complementary metasurgical treatments.

[Surgical problems in the aged patients].

Authors, considering the increasing of the middle duration of life and the increasing of geriatric population, examine various surgical problems in the elderly. They took in consideration not only the age, but all the other markers of surgical risk related to the surgical illness, to the associate illness and to the type of operation. After reporting their experience in the treatment of geriatric patients, they conclude that a scrupulous surgical preparation, a correct indication to the operation and an accurate overseeing after surgery are necessary to do that the elderly patient faces surgical intervention with the same capability of success of the young.

[Primary hyperparathyroidism].

Primary hyperparathyroidism is a hormonal disease that is more and more frequent and is often manifested exclusively by an increase in calcium levels in the serum. After examining the main anatomopathological and clinical characteristics of the disease, the authors present their experience in its diagnosis and surgical treatment. They suggest that cervical exploration with removal of the adenomas and hyperplastic glands in both asymptomatic and highly symptomatic patients is strongly advised. Since it is already possible to obtain an early diagnosis of the disease thanks to multicanal hematochemical equipment, the Authors conclude that in the near future, studies on cellular receptors for calcium will allow new therapeutic treatments to be applied.

[Neuroendocrine tumors of the pancreas].

Neuroendocrine tumours are rare and often include insulinoma, gastrinoma and other low frequency tumours that secrete gastrointestinal hormones. Their preoperative localization, despite continuous medical advances, is extremely difficult but helpful in guiding the surgeon towards a proper form of treatment. After presenting their cases, the authors conclude that the treatment of choice for these tumours is surgery due to their anatomopathological features (benign, scarcely malign or invasive, slow growth). On the other hand, medical therapy plays an important role in either preparing the surgical intervention or alleviating symptoms when the patient is inoperable.

[Primary hyperparathyroidism: follow-up of the surgically treated patient].

After several remarks on the etiopathogenesis of primary hyperparathyroidism the Authors emphasise the importance of follow-up in operated patients. The evaluation begins right after removal of the lesion in the intraoperative phase, in order to evaluate the validity of the intervention and continues with evaluation of mineral homeostasis, disease itself and function of target structures. In addition to possible hypocalcemic crises, special attention should be placed on possible disease recurrence, and the study of all involved parts such as bones, kidneys, pancreas, digestive apparatus as well as the psychological aspects. These are often involved in a significant manner and condition the quality and duration of the patient's life.

[Miles operation in rectal carcinoma: history and current status].

The Authors confirm how the advent of mechanical suture has directed the management of rectal carcinoma to an increasingly conservative attitude. In reporting their experience--which consists of about twenty years (222 patients) they specify how not only an increased incidence of recurrence has not appeared, but they have also observed a reduction of theirs (-5.2%). They then attempt to outline basic moments which have characterized the history of rectal carcinoma surgery and they state how today, 80 years since it was conceived, Miles' intervention maintains its validity, even if with more restrictive indications.
