Malignant schwannoma of the rectum: a clinical and pathological contribution.

Schwannomas of the rectum are uncommon and incompletely characterized tumours, and only a limited number of cases have been reported. On the basis of a case of rectal schwannoma and a review of the literature on this rare condition, we stress the importance of the clinical features, diagnostic difficulties and surgical indications for the various therapeutic approaches. The basis for radical operation, due to the tendency of such tumours to recur locally and the real possibility of malignant degeneration, is discussed. We also emphasize the difficulty of making a benign diagnosis with histological certainty.

[Polypropylene mesh in the surgical treatment of inguinal and crural hernia: our experience with 500 cases].

The authors guided by their personal experience (612 abdominal hernioplasties performed between 1992 and 1998) after using for the cure of inguinal and femoral hernias diverse prosthesis illustrate the characteristics of the polipropene prosthesis which in their opinion possesses every requirement necessary to enable it to become the defining ideal prosthesis. The authors underline again the use of this routinely applied prosthesis, also in a local anaesthesia it has favoured the development of the tension-free and suture-less technique which hes allowed hernioplasty to spread in day-surgery.

[Use of PTF prosthesis in hernia in the elderly].

The paper reports the author's experience of the use intraperitoneal of Gore-Tex Dual Mesh Biomaterial in large incisional hernia operations in patients over seventy. From January 1999 to December 1999 we operated on 24 patients for treatment of abdominal wall defect. In all patients we used a Dual Mesh Plus Biomaterial. Overall mortality was 0. Morbility was 9.5%. Follow-up is too short for definitive considerations about the incidence of recurrences but our initial experience with this material encourages us to use it again for replacement of abdominal wall defects in the age.

[Acute hemorrhage caused by duodenal ulcer. Results of endoscopic treatment of the first bleeding episode and of recurrences].

BACKGROUND: The aim of this study was to evaluate the impact of immediate endoscopic treatment of bleeding and rebleeding on the clinical outcome of patients with duodenal ulcer hemorrhage. MATERIALS AND METHODS: Between January 1995 and December 1998, 445 patients with bleeding duodenal ulcers were observed in the First Division of General Surgery--University of Verona. All patients, except two who died for hemorrhage before the endoscopic examination, underwent emergency endoscopy within 2 hours from the admission and ulcers with active or sign of recent bleeding were submitted to injection therapy. History, clinical and endoscopic findings, recurrent bleeding and outcome were prospectively collected and analyzed. Recurrent bleeding underwent immediate endoscopic retreatment as first attempt. RESULTS: Endoscopic therapy was performed in 277 patients with active bleeding and hemostasis was initially obtained in all patients except one. Rebleeding occurred in 62 patients (14%) and endoscopic treatment was successful in 85% of first rebleeding and in 58% of the cases with 2 or more rebleeding. Multivariate analysis showed that systolic blood pressure at admission, ulcer size and Forrest classification influenced independently the recurrence rate. The 30 days mortality was 12.2% in the whole series: 35 deaths (9.2%) in the group without recurrence and 19 (30.6%) deaths in the rebleeding group (p = 0.001). Only 22 patients (5%) underwent surgical treatment with a higher mortality compared to not operated patients (36.4% versus 10.9%). CONCLUSIONS: Endoscopic treatment was associated with reductions of the risk of recurrent bleeding and surgery without increasing mortality rate.

[Ambulatory surgical treatment of primary hernia: our experience].

The authors report their personal experience (169 pz.) of the primary inguinal hernia repair in day surgery treated in local anaesthesia and by applying prosthesis according to latest "Tension-free and Suture-less" techniques. Results surely confirmed the validity of the method and the utility in creating centres concerning this type of surgery so that we are able to grant to the patient the best comfort that is to say a relevant reduction of the recurrence and a faster reintegration of patient's activities daily living.

[Dual mesh-plus for wall reconstruction in incisional and umbilical hernia in the aged].

The article reports the author's experience about the use of Gore-Tex Dual Mesh Biomaterial in large incisional hernia operations in patients over seventy. From January 1996 at present day we operated on 23 patients for treatment of abdominal wall defect. In all patients we used a Dual Mesh. Overall mortality was O. Morbility was 9.5%. Follow-up is too short for definitive considerations about the incidence of recurrences but our initial experience with this material encourages us to use it again for replacement of abdominal wall defects especially in the old patient.

[Surgical treatment of mucosal hemorrhoidal prolapse using a circular stapler].

We present a retrospective clinical study concerning our personal experience with the circular stapler in the treatment of hemorrhoids; the aim of this study was to evaluate the results of this surgical procedure, in terms of operative time, postoperative pain and rate of both short and long-term complications. Twenty-seven patients with grade 3 or 4 hemorrhoids, from January 1999 to June 2001, were included in the study. The main technical details of this procedure, requiring only a short learning period, are described and both short-term complications (such as severe postoperative pain, bleeding, urinary and fecal retention) and long-term ones (such as persistent or recurrent haemorrhoidal prolapse, anal stenosis) are analyzed. The reported results show that, in the presence of appropriate local anatomic conditions, this procedure is able to reduce the operative time, is almost painless and is characterized by low rate of complications.

[Predictive factors and treatment of small bowel adhesive obstruction].

Our study is based on a retrospective analysis about a ten years' control on patients with a small bowel adhesive obstruction (SBAO) due to primitive abdominal surgical operations. From the valuation of the obtained data and through a literatures review we tried to better define the best treatment. On 297 admissions of 248 patients with a diagnosis of SBAO 196 operations were performed, which indication was based on every clinical data, haematologic and radiologic examinations. Moreover, it was analysed the responsive factor that caused adhesions with a careful valuation of the primitive surgical operation and the possibility of recurrences. From this study it is evicted that SBAO can be considered as a surgical differentiable urgency, where there aren't any signs of intestinal strangulation or peritonitis, and where the principal etiologic factor is represented by colorectal operations in the male and gynecologic operations in the female. Morbility and mortality in the surgical procedures for SBAO show greater percentages than the elderly patients.

[Kaplan-Meier analysis].

Kaplan-Meier analysis is largely used in nephrology to estimate a population survival curve from a sample. If patients are followed-up until death, the survival curve can be estimated simply by computing the fraction survival at each time point. Kaplan-Meier analysis allows the estimation of survival over time, even when patients drop out or are studied for different lengths of time. In Kaplan-Meier analysis, the comparison between two survival curves is made by the log-rank test.

[Sentinel-node biopsy for breast cancer: our experience].

The method of sentinel lymphnode is a new procedure, suitable for the cases of early diagnosed breast cancers: identifying the first lymphatic station of the cancer, it can avoid the axillary lymphadenectomy in those women with primitive invasive and unifocal neoplasis of not more than 1.5 cm in diameter and without lymphnodal invasion. So it is reduced the frequency of postoperative troubles (sensitive and motor diseases, lymphedema). In our study, we have researched and identified, using radioactive isotopes, the sentinel lymphnode in 20 women suffering from subclinic breast cancer. We have obtained a percentage of 5% of false negatives. The optimal level of identification of the sentinel lymphnode and the good level of predictivity about the axillary lymphatic status, that we have obtained, represent a further confirmation of the surety and validity of this method.

[Day surgery for breast cancer in the elderly].

Early diagnosis of breast cancer and improvement of new technologies for identification and analysis of sentinel node allow more conservative surgical approaches, which guarantee both excellent local control and a good quality of life, also in elderly patients. We have studied a series of 28 women aged 70 years or older and affected by breast cancer. They underwent breast-preserving surgery either alone or in association with axillary lymphadenectomy and all of them had early discharge from hospital. This approach demonstrated to be safe and effective, so we may conclude that day-surgery treatment of breast cancer in these patients is possible in the majority of cases, is associated with low morbidity and is profitable for clinical, social and economic issues.
