Gastric submucosal neoplasms : new diagnostic and therapeutic procedures
No full textSubmucosal neoplasms can be found in the esophagus and stomach during radiologic or endoscopic examination; histological diagnosis, however, is not significant in many cases because sampling is difficult. Endoscopic biopsies usually do not allow to obtain tissue from the submucosal layer nor other techniques prove to be reliable enough. 23 patients, aged between 21 and 76 were studied over a period of 5 years; in 1 male large gastric folds were observed. Of the 22 patients affected by benign submucosal neoplasms, 2 underwent surgical operation; no significant samples were obtained in any of the 11 cases in which biopsy forceps had been used. In the remaining patients an electrosurgical snare for polypectomy was used; this technique proved to be successful in 77.8% of cases. It is often shown to be also a therapeutic method when polypoid neoplasms are found
Stadiazione preoperatoria del carcinoma gastrico con l'utilizzo della eco-endoscopia (EUS)
No full textAccurate staging of gastric malignancy can only be obtained at surgery and after detailed histological examination of the resection specimen. Endoscopic ultrasonography may provide accurate detection and staging of gastric cancer because of its ability to visualize both the intramural and extramural extent of the lesion and any adjacent lymph node involvement. From february 90 to april 91, 29 patients with a gastric carcinoma were studied endosonographically before surgery. All studies were performed with an Olympus EU-M3. Preoperative TNM classification and a prediction of the resectability of gastric cancer were done in every patient. The results were matched with those obtained with the histology of resected specimens according to the TNM classification 1987. Endoscopic ultrasonography was accurate in assessing the extent and depth of tumor infiltration. The overall accuracy rate was 90.5% (19 out of 21 patients). Overstaging occurred in 9.5% of the cases (2 patients); none understaging occurred. EUS was less accurate in assessment of lymph node metastasis; the overall accuracy rate was 57.1%. Distinction between reactive lymph node and small micrometastatic lymph node involvement could be hard. Local resectability was correctly diagnosed with EUS in each of 23 patients; in two patients an intramural mass with a deep infiltration into the surrounding tissue was correctly diagnosed. In our opinion EUS is an essential diagnostic procedure in the clinical staging of the gastric cance

Gauge Fields and Strings
No full textBased on his own work, the author synthesizes the most promising approaches and ideals in field theory today. He presents such subjects as statistical mechanics, quantum field theory and their interrelation, continuous global symmetry, non-Abelian gauge fields, instantons and the quantam theory of loops, and quantum strings and random surfaces. This book is aimed at postgraduate students studying field theory and statistical mechanics, and for research workers in continuous global theory
