According to the experience of the authors, comparison between two consecutive periods (1980-1994 and 1995-2000) has shown a substantial increase in splenic traumas simply treated by observation and monitoring. Their number in fact has risen significantly from 5 to 32. This has allowed a rise in the overall percentage of spleen conservation, which has increased from 16.4% to 52.9%. On the contrary, a reduction in surgical conservative operations has been observed, the number decreasing from 19 to 4. Such treatments require the same clinical conditions as non- operative treatments, but the latter have to be accompanied by efficient organization of intensive care and monitoring, in which surgeons and anesthesists, who are familiar with all the aspects of the problem, collaborate efficiently. Since this kind of organization has been achieved, the number of patients successfully treated without surgery has increased significantly. In a sample of 37 patients receiving non-surgical conservative treatment, the percentage of delayed splenectomies was as low as 5.4%.

The lipohyperplasia of the ileocaecal valve is a condition of rare clinical observation mainly characterized by an abnormal accumulation of adipose tissue along the submucosal layer of the ileocaecal valve. This pathology presents an unspecific symptomatology that can make difficult the differential diagnosis with a local neoplastic process. Sometimes this pathology can be the cause of gastrointestinal bleeding of unknown origin. The Authors report a case of their observation that requested an emergency surgical operation for the massive digestive haemorrage at presentation. The definitive diagnosis could have been precised only after histological exam.

Necrotizing infections are rapidly progressive potentially lethal bacterial diseases of the soft tissues. In based on the widely varying levels of soft tissues affected and the variety of the microflora, two types of necrotizing soft tissue infections need to be delineated: pure Chlostridial myonecrosis and other necrotizing soft tissue infections (NSTI). From an etiopathogenetic point of view NSTI can be secondary to perianal or urogenital abscesses, traumatic lesions, wound infections, trophic or decubitus ulcers, oral cavity abscesses; only in a limited number of cases their origin can be idiopathic. Exceptionally it can happen that a NSTI could represent the only clinical manifestation of a retroperitoneal colic perforation. The Authors report their experience regarding two clinical cases recently observed. The first patient, who previously underwent colic resection for sigmoid carcinoma and adjuvant chemotherapy, had developed as only clinical manifestation of retroperitoneal anastomotic fistula a necrotizing infection at the root of the hip, extended along the whole leg. The second patient, with diverticular perforated disease, had developed rhe necrotizing infection in the lumbar region and in the perirenal tissues. Here will be discussed the sensitivity of the possible diagnostic investigative techniques and the therapeutical strategies that brought both the patients to a complete recovery.

The authors report their experience using biofragmentable anastomosis ring (BAR) in bowel anastomosis. Starting January 1993 to February 1994, 46 intestinal anastomoses were performed using BAR, and particularly 39 end-to-end colo-colostomies, 2 end-to-side colo-colostomies and 5 end-to-side ileo-colostomies. 35 patients were affected by colonic neoplasm, 5 patients by diverticular colonic complications- and 5 patients by several unusual bowel diseases. Four emergency operations were performed, while 42 patients had an accurate bowel preparation before surgery. In this series of patients one case of preoperative mortality is reported, due to massive pulmonary embolism. Instead several minor complications occurred in other patients, such as paroxysmal atrial fibrillation (one case), basal pleuritis (one case), hyperpyrexia (three cases), temporary subocclusion or delayed canalization (five cases). Only one patient suffered from intestinal occlusion induced by adhesions and a second laparotomy was required. Delayed canalization seems to be caused by the small size of the BAR employed (25 mm) or by inadequate intestinal preparation, that usually occurs in emergency operations. After surgery all patients were followed up and 18 of them were examined by coloscopy six months after surgery. No clinical problem connected with bowel anastomosis was reported and all anastomosis looked quite previous and resilient. No anastomotic stenosis was found. In our experience and from recent reviewed reports, BAR seems to be a rapid, effective and safe device for sutureless bowel anastomosis.

Several authors assumed that spleen was resistant to neoplastic dissemination because of spleen metastasis are rare in relation to the incidence of metastasis in other parenchymatous organs. We report a clinical case of a symptomatic solitary spleen metastasis in cystic-looking bladder cancer; afterwards we'll examine real incidence of secondary splenic injury. In autopsy studies, the incidence of splenic metastatic spread is in contrast with the rarity of clinical manifestations of solitary metastasis. The case reported is really uncommon: a voluminous single metastasis, cystic-looking, with splenomegaly, abdominal pain and rapid onset. In the presence of a high malignancy primitive tumor, the evaluation of the effective utility of the surgical treatment carried out is premature, because of the relatively short follow-up. On the other hand, the painful symptomatology, the risk of disruption in peritoneal cavity, the impossibility to make inquiries about the nature of the cystic mass, imposed, in our opinion, a surgical treatment.

From January 1993 to December 1994, out of 244 cases of upper gastrointestinal hemorrhage observed 25 patients underwent surgical treatment. Twenty-nine bleeding varices were excluded from this study. Early endoscopy revealed the source of bleeding almost in all cases (84%). All patients received, at the time of admission, medical treatment associated in 7 cases (28%) to endoscopic injection therapy. Emergency surgery indications were massive bleeding persistent bleeding, rebleeding and macroscopic findings of lesions. The aim of this report is to verify the respective roles of medical, endoscopic and surgical therapies in relation to the nature of the bleeding lesion and the entity of the hemorrhage. Results with regard to indication, clinical data, surgical technique were compared with literature data.

The relationship between hyperthyroidism and carcinoma of the thyroid is still uncertain. The incidence of thyroid carcinoma ranges from 0.3 to 16.6%. Between 1984 and 1994 the Authors observed 9 patients affected with thyroid cancer and toxic nodular goiter (4 patients) or Basedow disease (2 patients) or scintigraphic evidence of single hyperfunctioning nodule (3 patients). Six out of the 9 cases were diagnosed as papillary cancer, while three as follicular cancer. A carcinoma was diagnosed before operation in only one case, while in the other 8 patients, the diagnosis was obtained by histological examination of the specimen. Four patients underwent subtotal thyroidectomy, while five patients underwent radical lobectomy. All patients are alive and in good health; the average follow-up was 48 months.
