[Gastric lymphomas: surgical indications].

Primary gastric lymphoma (PGL) are lymphomas with an exclusive gastric localization. Histologically they are B-like non-Hodgkin lymphomas. Aim of Authors' study is to define the role of surgery in the treatment of PGL, on the basis of their series casistics and a review of the more recent literature data. The Authors observed 41 patients (23 F and 18 M) in a period of 10 years: 35 patients underwent to surgical operation associated in 18 of them to chemotherapic treatment; in 6 cases medical eradication of Helicobacter Pylori (H.P.) was performed as unique treatment. Antibiothic treatment allows the eradication of H.P. in 97% of the patients and a histologic decreasing of MALT lymphoma in 70% of the patients in about 6 months. That represents the first therapeutic choice for the low grade of malignancy MALT PGL at I and II stages. In the cases of partial decreasing or progression of PGL, the Authors consider opportune surgical operation. In the majority of the cases the surgical option represents, according to our advise, the best choice for the high percentage of definitive recoveries, allowing a 10 or more years of surviving of the 90%, if it is done in the first stages of the disease. The results of the association with neoadjuvant or aduvant chemotherapy are still controversial. On the basis of their experience total gastrectomy can be considered the elective choice operation, with IID level lymphadenectomy and possible splenectomy.

[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.

[Varicose disease of lower limbs: our actual orientation].

A retrospective analysis of a series of patients treated during 5 years was made evaluating, on the basis of the clinical and ultrasonographic examination, the results obtained in the treatment of the varicose disease of the lower limbs for each one of three surgical methodic employed (crossectomy, long or short stripping) as well as patients compliance. All the patients previously underwent ultrasonographic examination to evaluate the reflux rank of the internal saphena and to point out every insufficient veins. On the basis of specific indications, from routinary pre-operative and anaesthesiologic examinations, all the patients were operated. Totally, 784 operations were performed. Thanks to the follow-up, carried out through an objective evaluation (echocolor-Doppler) and subjective one (degree of satisfaction fullfilled through some tests), it is concluded that the most favourable method, among those used, is that of short stripping with wrapping up a silk thread, in accordance to Van der Stricht.

Abscess and cecum carcinoma in inguinal hernia: case report.

Cecal adenocarcinoma within an inguinal hernial sac is an uncommon clinical condition. A primary adenocarcinoma of the cecum in a right sided inguinal hernia is presented and discussed. This case represents one of the unexpected findings in a hernia sac and also very rare septic evolution. This particular condition is a main dignostic and therapeutic challenge.

Pathological evaluation in colorectal polyps endoscopic treatment.

This retrospective study shows that endoscopic polypectomy is the technique of choice to remove the majority of polyps; follow-up and pathologic examinations shed light on the carcinogenesis of colorectal lesions. From January 1990 to December 2001, 1302 adenomatous polyps were removed, 1175 endoscopically, 127 with surgical procedures. The anatomical and morphologic conditions of the colon and some characteristics of the polyps represent limits to the feasibility and to the efficacy of polypectomy, and the most important variables for the correct management of the patients affected by colorectal adenomatous polyps.

A multicentre study on LMW-heparin effectiveness in preventing postsurgical thrombosis.

A multicentric study was carried out involving six italian departments of general surgery to assess the efficacy of a low molecular weight (LMW) heparin called Fluxum compared to standard calcium heparin in low doses for prevention of postoperative thromboembolic complications (deep vein thrombosis and pulmonary embolism). 610 patients were treated; 308 (50.5%) of whom were treated with Fluxum at doses of 4,000 or 8,000 I.U. Axa once a day by subcutaneous injection and 302 (49.5%) with heparin calcium at doses of 5,000 I.U. two or three times a day by subcutaneous injection. We observed a total of 29 deep vein thrombosis (4.7%); 10 (3.2%) from the group treated with LMW heparin and 19 (6.3%) from the comparative group. During the study 4 (0.65%) pulmonary embolism were found, 1 (0.32%) in the group treated with LMW heparin and 3 (1%) in the group treated with calcium heparin. None serious hemorrhagic accident was reported during the study. The antithrombotic prophy laxis carried out with Fluxum was on the whole better tolerated than the treatment of the other group, registering a lower frequency of hematomas at the injection and surgical wound sites.

Follow-up study in 402 patients after parietal cell vagotomy for duodenal ulcer.

In a recent six-year-period, a total of 402 patients underwent parietal cell vagotomy (PCV) for duodenal ulcer. An overall clinical assessment by Visik grading placed 328 (82%) in grade I, 56 (14%) in grade II, 12 (3%) in grade III and 4 (1%) with recurrent ulcer in grade IV. Results of the gastric secretory tests showed that the basal acid output (BAO) was reduced by 83.9% of the preoperative value, after 3 months, by 78.2% after one year, and by 65.3% and 66.4% after three and five years respectively. The maximal acid output (MAO) was reduced by 75.9% of the preoperative value after 3 months, by 45.3% after one year, by 40% and 42% after 3 and 5 years respectively. The radiological gastric emptying time showed no significant difference when compared to the preoperative value. The parietal cells showed significant ultrastructural changes six months after PCV, corresponding to maximum functional secretory depression. Two years after the operation, the parietal cells had regained their preoperative morphology.

[Hepatitis B virus (HBV) infection in health personnel of a hospital for adolescents. Results of a vaccine campaign].

The aim of the research is to evaluate the professional risk of the health workers of a pediatric hospital, mainly devoted to the care of adolescents. A seroepidemiological survey was therefore performed during the preliminary screening of an anti-hepatitis-B vaccination program, implemented in a suburban 150-beds pediatric hospital, with a predominance of elective surgery patients. The prevalence of past or ongoing HBV infection in a sample of adolescent inpatient (10-19 years old) in the same institution was known from an another study (13.2%). The prevalence of any HBV marker among 360 workers was 16.3%, lower in males (13.5 versus 17.7% in females), and in those with an higher level of instruction; the prevalence resulted significantly higher with increasing age and length of hospital service. Out of 321 candidates to anti-HBV vaccination 245 employees accepted the procedure (76.3%), significantly more females than males (80% versus 68.9%) and more subjects less than 30 years-old (84.3% versus 62% of subjects more than 40 years-old subjects). Only 13 subjects (5.3%) did not reach a protective titer after the third dose of the plasma-derived vaccine a protective titer. No major adverse event occurred.
