[Intestinal invagination caused by submucous pedunculated lipoma of the large intestine].

A case of colo-colic invagination caused by lipoma of the splenic flexure which led to emergency operation is reported. Colon lipomas are benign neoformations of the submucosa with prevalence of the right colon and with a frequency of from 0.3% to 5.8% in the whole population depending on clinical or autoptic series. Radiological and endoscopic investigations provide orientative elements for diagnosis. The most frequent complications are bleeding and intussusception in 50% of cases. Surgical removal may be carried out, preferably segmentary resection, so as not to be forced to operate on a complication in emergency conditions.

[Use of computerized axial tomography and transrectal echography in the preoperative evaluation of cancer of the rectum].

Eight patients were subjected to two types of preoperative investigation in the attempt to stage cancers localised in the final 13 cm of the rectum: CT scan and transrectal echography. CT scan was used to assess infiltration of perirectal tissues and any lymph node metastases. Echography was used to examine the degree of infiltration of the rectal wall. Patients were then submitted to surgery. The predictivity of these studies proved sufficiently high. 7 Miles amputations and 1 anterior resection were carried out. One case only in which the scan did not show signs of parietal lesions presented two perirectal lymph node metastases. If refined further, these evaluations will therefore influence surgical tactics.

[The role of cytology by needle aspiration in the diagnosis of thyroid nodules. Examination of 179 cases].

Since May 1981, fine needle biopsies have been used for cytological examination of thyroid nodules that were barely or not recorded by scintiphotography. By February 1984, a total of 179 patients had been examined. The biopsies were repeated on 12 patients where the first sample produced no diagnostic material. In 57 cases, a histological control existed in the form of material removed surgically by enucleoresections, partial and total thyroidectomies. Histological examination confirmed the cytological diagnosis in 7 out of 8 cases (88%) of malignant neoplasias with varying degrees of differentiation. A cytological diagnosis of adenoma was reached in 80% of cases, and of nodular struma in 82% of cases. Microscopic aspects of the cases are described together with the consequent cytological diagnostic criteria, while the characteristics and importance of the technique are also discussed.

[Rehabilitation of patients after colostomy. Personal experience].

Personal experience of aiding 58 colostomised patients is reported. Certain basic aspects of aid in the immediate and later postoperative period are emphasised: diet, stools, irrigation, psychological support. Follow up showed that most patients returned successfully to normal life, returning to work and in some cases to the practice of sports.

[Use of single-layer anastomoses in intestinal surgery; experimental and clinical studies].

Reference is made to an experimental and clinical investigation of single-layer intestinal anastomoses. The techniques of Gambee, D'Onofrio, Lembert, Halsted Connel were applied in six groups of 10 rabbits. The survival and weight data, gross and microscopic inspection, and the stenosis index showed that the best results were obtained with Halsted's, D'Onofrio, and Gambee's techniques. An account is also given of a clinical series of 124 patients in which Halsted's technique was employed.

Management and long-term results in patients with two-thirds gastrectomy and stomal ulcer.

In 67 patients with two-thirds gastrectomy and endoscopically proven stomal ulcer, serum gastrin levels were measured under basal conditions and after intravenous infusion of bombesin (15 ng/kg/min), calcium (4 mg/kg/hour) and secretion (2 units/kg). All patients underwent medical or surgical therapy. The long-term results were evaluated according to the Visick grading system (average follow-up, 3.1 years).

Study of sentinel lymph node in breast cancer: our experience in 46 cases.

At the Surgery Department of Biella 46 patients were enrolled in a study on the sentinel lymph node (SN) in the period from 1 January 1999 to 30 September 1999. The aim of the study was to determine, on the basis of our own experience, the percentages of accuracy and concordance, and compare them with case series abroad and in Italy; in addition, we sought to establish a possible correlation between certain features of breast cancer and positivity of the axilla. The method utilized was lymphoscintigraphy and gamma probe. Fifteen cases with positive axillary lymph nodes and 12 cases with positive sentinel lymph nodes were found; there were no false positive and three false negative results. No migration of the tracer was observed with lymphoscintigraphy in two cases. The percentage of concordance obtained was 93.2% in the complete series and 96.5% in the subseries that excluded the learning curve. Comparing the percentage of concordance of our case series with those abroad and in Italy, an average overlapping percentage was obtained. The percentage of accuracy obtained in our study was 95.7%, which is slightly higher than the average of percentages of the case series abroad and in Italy.
