[Endoscopic treatment of polyps of the large intestine: authors' experience with 250 cases of polypectomy].

The Authors report their experience of endoscopic polipectomy. This technique represents a gold standard treatment for polyps of the colon-rectum because it is safe and effective, being correlated with low-risk of complications as perforation and hemorrhage. Hospitality stay was only 24-48 hours. The polyps were histologically examined and grade of dysplasia was determined. The patients underwent surgical resection of the colon when an invasive carcinoma was found.

Adenomas with severe dysplasia and early carcinoma of the colon-rectum: our experience of 27 patients.

Authors report their experience in the treatment of adenomas with severe dysplasia and early cancer of the colon-rectum confirming that the endoscopic resection of these lesions is safe and curative when completely removed and no submucosal invasion is found. Between 1995 and 1999, 219 patients underwent colonoscopy and 287 polyps were removed. Histologic examination showed 217 adenomatous polyps (75.6%), 58 non adenomatous (20.2%) and 12 early carcinomas (4.2%). Severe dysplasia was found in 15 adenomas. There were no complications. The Authors focused on 12 patient with early carcinoma and 15 with severe dysplasia. The mean follow-up was 34 months. No recurrences were observed, supporting that this procedure is the treatment of choice in selected cases.

[Our experience with the appropriate use of esophagogastroduodenoscopy].

Many studies emphasize the right indications about the execution of an EGDS showing that a lot of requests are inappropriate. We have wanted to report our experience too, that showed more comfortable results than that checked, by other Authors moreover we have emphasized that the inappropriate requestsare justly divided between generical and specialized physicians.

[Endoscopic prosthesis in colonic malignant pathology].

The utilization of stents in neoplastic colon pathology finds a correct location in the therapeutic panorama. Authors report the use of enteric stents as definitive treatment in acute intestinal occlusion with inoperable malignant neoplasia as well as palliative treatment in intestinal occlusion with non-surgically resectable neoplasia.

[Malignant peritoneal mesothelioma: apropos a new case].

Prognosis for patients with malignant peritoneal mesothelioma is very poor, and most patients are beyond cure by the time the diagnosis has been made. The pathogenesis of this uncommon neoplasm seems to be related to asbestos and radiation exposure. The authors report a case of diffuse peritoneal mesothelioma in a 33-year-old man. Since the patient complained of aspecific symptoms and both biochemical and "imaging" studies did not provide useful informations for a definitive diagnosis, an exploratory laparotomy was performed. Intraoperative histological findings demonstrated the presence of a malignant peritoneal mesothelioma which had spread all over the omentum; considering the inoperability assessment of this case, the operation was completed and the patient was dismissed with an adjuvant chemo-therapy. Five weeks later the patient died.

[Study of fecal antigens against Helicobacter pylori as non-invasive test compared with the 13C-urea breath-test. Personal experience].

The target of this study is the evaluation of two different noninvasive tests: 13C-urea Breath-Test, as gold standard, versus the HpSA test, as new method to research the faecal antigen of Helicobacter Pylori (HP). Thirty patients, affected by dyspeptic symptomatology and never treated before by antibiotic therapy to eradicate the HP, was subjected, by Authors, to this evaluation. This study say that the 13C-urea Breath-test represent the gold standard in the pre-endoscopic research of HP presence concerning specificity and sensibility. However, the HpSA test need more improvement.

[Percutaneous endoscopic gastrostomy (PEG)].

When gastric decompression or enteral feeding are needed for patients affected by neurological problems or neoplasias with a long life expectancy (months), PEG represents the method of choice because it has a lesser number of complications, needs a mild sedation, and has a lower cost compared to surgical techniques.

[Pneumatic dilatation in the treatment of esophageal achalasia].

The purpose of therapy in esophageal achalasia is to reduce the pressure at the level of the lower esophageal sphincter. In this study 26 patients (16 males and 10 females) between 30 and 50 years of age, affected by esophageal achalasia underwent esophageal dilatation with Rigiflex pneumatic dilators. A total of 40 dilatations were performed. A complete success using the Rigiflex pneumatic dilators, was achieved in 24 out of 26 patients (92.3%).
