Background and Objectives: Geriatric population life expectancy is rapidly increasing and the impact of major surgical procedures is not well defined. The purpose of this study was to compare short term surgical results assessing mortality and morbidity and long-term survival and disease-free interval in elective rectal surgery patients older than 65 years of age. The main independent risk factors of mortality, morbidity, and overall and disease-free survival were also identified.Methods: Out of 177 rectal cancer accepted consecutively from 1991 to 2002, we studied the main clinical and pathological parameters comparing patients older and younger than 65 years. Data have been collected in a database and variables considered were studied by univariate analysis; independent predictive factors of 30-day mortality and morbidity were identified by multiple logistic regression analysis. Overall, cancer specific and disease-free survival curves were obtained with the Kaplan-Meier method and results compared with the log-rank test. Independent risk factors of overall and disease-free survival have been identified by multivariate logistic regression analysis.Results: In patients younger and older than 65 years postoperative mortality (3.2% vs. 9.6%) and morbidity (30% vs. 29%) were not significantly different. Variables independently associated with 30-day mortality were the duration of surgical procedures and postoperative complications. The Kaplan-Meier survival curves showed a significantly worst overall survival (P = 0.003), cancer specific survival (P = 0.02), and disease-free survival (P = 0.03) in patients aged 65 years or more. Multivariate analysis showed that pT, grading, preoperative CEA level, gender, and site of the tumor along the rectum, the number of blood transfusion and the age group of more than 65 years are independent risk factors for both overall survival and disease-free interval. The presence of residual disease was an adjunctive factor of overall survival, whereas the Astler and Coller staging was a risk factor for the disease-free survival.Conclusion: The short-term prognosis for elective rectal cancer procedure in patients over 65 years of age was comparable to that of younger patients, whereas long term cancer-related survival was statistically worst in older patients.

AIM:To identify the main parameters which, differently correlated, indicate in which case, age and modality umbilical hernia in children should be surgically repaired.METHODS:The authors report personal experience on 319 children with umbilical hernia observed in the last 7 years. In 72 cases, on the basis of the evaluation of some parameters, a surgical correction was performed with the technique described.RESULTS:All the procedures were performed in "day surgery". There were no early complications, neither anesthetic nor surgical. All children showed a good recovery of all functions (feeding, intestinal canalization, walking about) and activities. No middle and long-term complications were observed.CONCLUSIONS:Umbilical hernia needs a surgical repair only in a few cases and after a careful evaluation of some parameters (age, sex, kind of hernia, size and consistency of the hernial porta, protrusion and expansion). The surgical procedure should guarantee either the safe and prompt repair or the cosmetic result; the use of some devices (anesthetic and surgical) allow to obtain excellent results.

The Authors report their experience with 25 patients operated for colorectal junction neoplasms from January 1998 to December 2002 in the Section of Oncological Surgery, at Perugia University. According to the international literature, the Authors maintain the absolute functional and anatomical individuality of this part of the large bowel, underlining the peculiarity of the sigmoidal junction neoplasms respect all the others colic sites regarding clinical manifestations, symptoms developing and biological behaviour. The characteristics seem also capable of changing the surgical choice as well as the prognosis of the disease.

The Authors carried on a retrospective study of risks factors in oncologic surgery based on a univariate analysis. The study includes 337 patients hospitalized for neoplastic pathology from January 1991 to June 1995. In agreement with Literature the most important risks factors were represented by associated pathologies, TNM staging and ASA classification. The opportunity of a correct preoperative evaluation of risks factors is recommended to assure the best conditions for the surgical patient and to rescue to surgery patients otherwise considered not surgically manageable.

The operative treatment of thyroid pathology has to be distinguished for benign and malignant pathology. The major complications associated with thyroid surgery are injury to the recurrent laryngeal nerve and hypoparathyroidism. Postoperative hypoparathyroidism is rarely the result of inadvertent removal of all parathyroid glands but, non commonly, is due to disruption of their blood supply. Postoperative hypoparathyroidism results in patients with symptomatic hypocalcemia, transitory and permanent hypoparathyroidism. Subtotal thyroidectomy is used for the treatment of benign thyroid pathology while tumors are treated by total thyroidectomy with neck dissection.

The Authors report their experience in the management of surgical hyperthyroidism, evaluating the different clinical pictures and the possibility of non surgical treatment. Advantages and disadvantages of both hemithyroidectomy and total thyroidectomy, are also described. The Authors conclude affirming their preference for techniques such as total hemithyroidectomy or thyroidectomy in some types of hyperthyroidism.

The operative management of patients with hyperparathyroidism is controversial. High rates of persistent hypercalcemia and postoperative hypoparathyroidism are seen in multiple hyperplasia and bilateral neck exploration. Patients undergoing unilateral neck exploration with removal of a single parathyroid adenoma have a rapid clearance of PTH which declines within hours after surgery. There is a sensitive immunometric assay (IRMA) for the intact molecule which demonstrates a decline in 15 minutes during surgery. Intraoperative measurement of PTH may be complementary to surgical skill and histopathologic information and may modulate extension of neck exploration.
