[Surgical treatment of pancreatic pseudocyst].

The review of diagnosis and treatment of 18 pancreatic pseudocysts has led to some conclusions about controversial aspects of the surgical management. The accuracy of imaging techniques in the early detection of the pseudocyst is high and plays a major role in the demonstration of its spontaneous resolution and evolution. The optimal surgical treatment of uncomplicated pseudocysts is the internal drainage, most rarely their resection. The incidence of septic complications was 22%: in this case the pseudocysts are usually best managed by external drainage.

Malignant stromal tumor consistent with fibrosarcoma arising from Meckel's diverticulum. Clinicopathological study of an incidentally discovered tumor and review of the literature.

The authors report a case of a Meckel's diverticulum mesenchymal tumor incidentally discovered in a 69-year-old woman undergoing laparotomy for an ovarian cyst. Histological examination of the tumor revealed a fasciculated proliferation of spindle cells that proved to be immunoreactive to vimentin only; pleomorphism was mild, necrosis extensive and mitotic count high. Because these features were consistent with those of fibrosarcoma, the tumor was classified in the category of gastrointestinal stromal tumors; more specifically, it was considered malignant for the presence of spread beyond the primary site in the form of peritoneal nodules and for the high mitotic count. We have been able to find only one previously reported case of mesenchymal malignant tumor of Meckel's diverticulum classified as fibrosarcoma among the 199 malignant tumors described in the literature. Based on this personal experience and on the review of the literature concerning malignant tumors of Meckel's diverticulum, we discuss both the rarity of these tumors and the importance of removing Meckel's diverticulum every time it is found during laparotomy.

[Damage control surgery: the technique].

Abdominal packing and planned reoperation is a lifesaving technique for temporary control of haemorrhage in severely injured patients. Morbidity and mortality, however, remain significant. The purpose of this study is to evaluate all surgical technique and our results during 31 years of trauma surgery. In the last 12 years the Authors have performed 11 packing. They stressed fully "damage control technique" in trauma surgery in the last four years. Overall mortality was 45.5%.

[Surgical management of trauma: from the "golden hour" to the "Golden Day"].

The treatment of the "trauma" has individualized objective therapeutic to reach in the first phase of clinical management defined by Mattox in the concept of the Golden Hour, that consist to transport the patient to the fittest hospital and to recognize and to treat the priorities "ABCDE", identifies in ATLS Guideline. The evolution of the organization for the treatment of the trauma has developed the concept of Trauma System to whose apex there are of the structures devoted define Trauma Center, with specificity of structures and functions, personal devoted fully grown with a specific run. In the Trauma Center is possible to get a therapeutic planning according to the priorities of the case in few times so that to not only achieve the objective to treat in emergency the vital lesions, but to do the necessary treatments precociously to prevent the compliances of the patient, that is checked in environment then multidisciplinary intensive care. This systematic treatment by objective it allows to identify some Guideline of surgical treatment for priority in once defined Golden Day.

[Superior vena cava syndrome].

Superior vena cava syndrome is due to an intrinsic or extrinsic caval obstruction that evolves in acute or subacute way with distinctive clinical feature such as respiratory symptoms and venous stasis. Since 1998 we have treated three cases of spontaneous superior vena cava thrombosis in neoplastic patients who underwent several infusion of chemotherapy, respectively for a breast, uterine and rectum cancer. All patients was female, 52, 58 and 70 years old. The first two cases was treated with locoregional thrombolysis by infusing Urokinase 50,000 UI/h during 24 hours and Urokinase 50,000 UI/h during 12 h the third one. After that, we have positioned a 16/9 wallstent: in the first two cases directly into the superior vena cava, in the third case in the subclavian-anonyma truncus. We had in all cases the complete opening of the stent within the first 48 hours without complications, enabling us to reach a free caval diameter of about 2 cm with resolution of the clinical signs. In patients with high surgical risk, the caval wall-stent is the first choice to solve the vein recanalization.
