[The role of endoscopic sphincterotomy in the therapy of choledocholithiasis: a review of our experience].

The treatment of common bile duct stones is nowadays endoscopic sphincterotomy. The authors reviewed their series from 1992 to 1999 and confirm that this is a safe, definitive, with low complication rate treatment if is performed in specialized centers and reduces the duration of hospitalization. Operative ERCP is successful is about 96-97% of the cases. There was no mortality related to the technique.

[The emergency management of foreign bodies: our own experience in 46 cases].

Foreign bodies ingestion is a common cause of emergency endoscopic therapy. Usually ingestion is accidental for children and elderly patients, instead is voluntary in some others as psychopathic people or prisoners. The authors report their experience with 46 cases from January 1992 to December 1998: this technique is safe, with low rate of complications and hospitalization.

[Endoscopic polypectomy in benign adenoma and in early colo-rectal lesions].

The Authors report their results in 219 patients who underwent endoscopic polypectomy for benign adenomatous polyps and early colorectal cancer. This is safe and curative technique associated with low-risk of complications and in an ideal therapy to prevent the development of colorectal cancer. In fact, nowadays, dysplasia-carcinoma sequence has been described. All polyps were histologically identified and the grade of dysplasia always detected.

[Current status of the use of the endoscopic cholangiography technique].

The endoscopic retrograde cholangiopancreatography as a diagnostic technique employed to obtain an accurate radiological study of the biliary path, and the biliary duct-pancreatic-duodenal junction. However, during the initial diagnostic studies, both echography and nuclear magnetic resonance have taken a priority. Currently, their importance is as a preliminary diagnostic method during endoscopic intervention.

[Endoscopic treatment of benign esophageal stenosis].

Benign esophageal stenosis is the most frequent type of stenosis of the digestive tract. Surgical treatment is still affected by a high percentage of morbidity and mortality. This is not acceptable for a condition which is not neoplastic in nature. The introduction of modern endoscopic instruments has significantly simplified the technique also reducing the complications, therefore oesophageal dilatation has a fundamental role. The main indications to endoscopic treatment are represented by postoperative stenosis, and those caused by caustics, peptic acid, actinic lesions and achalasia. During the past 15 years, the Authors performed 205 endoscopic dilatation including 26 cases affected by esophageal achalasia. In the experience of the Authors, olivarian metallic probes were gradually abandoned in favour of Celestin & Savary polimetric dilators while pneumatic dilators were preferred only in achalasic cases. Endoscopic therapy was resolutive in 24 patients affected by achalasia (92.3%). In 158 patients, mechanic dilatation was employed (88.2%) and among them, 4 cases (2.19%) of esophageal perforation were observed. Overall, mortality rate was zero. As far as the average number of dilatation employed, the highest number was registered among caustic lesions (5), followed by peptic (4), and post-operative stenosis (1). The results obtained confirm the validity and efficacy of the endoscopic treatment for benign esophageal stenosis also considering the good compliance of the patients and the fact that no general anaesthesia is required.

[Endoscopic ligation and sclerotherapy in the treatment of esophageal varices].

Endoscopic variceal ligation (EVL) and esophageal variceal sclerotherapy (EVS) are both used in the treatment of esophageal varices. Sclerotherapy is widely used with success, however it is associated with multiple local and systemic complications. To overwhelm the complications of sclerosis, Stiegmann in 1986 proposed the elastic band variceal ligation which demonstrated to be efficient as sclerotherapy though with minor side effects. Therefore, the Authors decided to apply a therapeutical protocol with EVL for the primary prevention of variceal esophageal bleeding. Preliminary results are herein reported.

[Polyethylene glycol versus sodium phosphate: comparison of 2 preparations for colonoscopy].

The intention of this study is to compare the efficacy and tolerability of an electrolytic solution containing polyethylene glycol (PEG) with a saline solution containing sodium phosphate in the preparation of colon for an endoscopic examination. 80 patients were subdivided at random into two groups: Group 1; PEG 4 liters - Group 2; sodium phosphate 3 packets plus one microenema. The efficacy of the two preparations was decided on the basis of: presence or absence of liquid/solid faecal residues observed by the endoscopist during the exploration of the large intestine, and classified as follows: perfect, good, mediocre and bad. Acceptability was established on the basis of patient tolerability in completing or not the preparation as well as presence of any side effect. The PEG solution was observed to be more efficient than sodium phosphate solution while both preparations had comparable tolerability. The cost of the PEG preparation was higher compared to the sodium phosphate preparation.

[Bizarre gastric leiomyoblastoma. A case report and review of the literature].

Gastric leiomyoblastoma of Martin's myoid tumour or Stout's smooth muscle cell bizarre tumour is a rare benign mesenchymal neoplasia, that may become malignant. A personal clinical case is reported and the most important clinical and anatomopathological aspects are reviewed, stress being laid on the importance of identifying the macroscopic and histological features that can point with certainty to malignity and so influence the choice of surgery.

[A case of anaplastic carcinoma of the thyroid. Clinico-pathological and therapeutic aspects and review of the literature].

A case of anaplastic carcinoma of the thyroid observed in a 72-year-old female patient, admitted with previous diagnosis of Riedel's thyroiditis, is reported. Clinicopathologic features and management of this rare neoplasm are discussed and Literature is reviewed. Anaplastic cancer is a locally and systemically aggressive histologic type, occurring more frequently in older patients and in those with a history of benign and/or malignant thyroid disease. Because long-term survival was seen most commonly in well-localized anaplastic tumors, a more aggressive approach to thyroid lesions, especially in the elderly, may be warranted to improve early diagnosis and effectiveness of therapy of this nearly always lethal neoplasm. Although patients can rarely be cured, efforts should be made to control the disease locally by combined treatment including surgery and radiochemotherapy, which is found to be, at times, a national palliative therapeutic approach despite patient's advanced age.

[Use of human fibrin glue (Tissucol) in the treatment of recurrent fistulas].

In this study, the treatment of either primitive or secondary abdominal relapsed fistulas with Human Fibrin Glue (Tissucol) is reported. Twelve patients with different types of fistulas were treated in day hospital with the above mentioned procedure. Apart from two patients, the good percentage of success obtained in a short period of time is stressed. Results show that such a technique may be favourably adopted, nevertheless a correct first surgical procedure is recommended.

[Lymphoma of the residual gastric stump].

The authors report a case of non-Hodgkin's lymphoma (lymphoplasmocytoid type) arisen on the gastric stump of a patient operated 18 years before according to Billroth II gastric resection for peptic ulcer. They underline the extraordinary rarity of the event because this type of neoplasia never arises on the gastric stump, where would be more likely to find, due to irritative chemical stimuli of the biliary reflux, phenomena of intestinal metaplasia or severe dysplasia highly predisposing to adenocarcinomas. Furthermore, they stress the importance of a "deep" bioptic examination for a diagnosis as early as possible of this type of pathology.

Primary hyperparathyroidism. A case report.

A case of primary hyperparathyroidism due to diffuse parathyroid hyperplasia, with thyroid goiter, bilateral renal lithiasis and fibrocystic osteitis is reported. Precise identification of parathyroid glands was achieved by U.S. and U.S.-assisted fine-needle aspiration. The role of the different diagnostic procedures has been evaluated in order to assess preoperatively a correct surgical approach.
