[Acute pancreatitis: resultos of a diagnostic-therapeutic protocol in 80 consecutive cases]. / Pancreatiti acute: risultati di un protocollo diagnostico-terapeutico in 80 casi consecutivi.

The treatment of acute pancreatitis cannot be standardized in the absence of a prompt diagnosis and of an accurate severity and prognostic score. This study, based on 80 consecutively observed patients, compared the aetiological, clinical, diagnostic (laboratory and imaging) and prognostic data used to select the most appropriate therapy for each patient. The results confirm that the Ranson score shows a satisfactory prognostic relationship between the number of positive parameters and the severity of the disease. Ultrasound, which is useful for defining the aetiologic factors and in the follow-up of peripancreatic effusions, has proved to be limited as a means of imaging abnormalities of the pancreatic parenchyma. CT scans are confirmed as being the only method of accurately demonstrating the presence of necrosis and of evaluating its effective extent. ERCP was performed as soon as possible in the presence of biliary stasis or of suspect ultrasonographic signs. Surgical treatment proved necessary only in 7.5% of cases, on each occasion to drain infected necrotic foci. Promptness of the surgical indication plays an important role in the outcome of necrosectomy and drainage performed with the closed technique. Mortality was limited to 1.25% in our series. A correct diagnostic approach together with prompt treatment can reduce the mortality rate of this disease to a minimum.

[Vascular trauma of the upper extremities]. / I traumi vascolari degli arti superiori.

The aim of this study was to evaluate short- and long-term results of the treatment of upper extremities vascular trauma considering aetiology of the lesions, percentage of limb salvage and residual functional disability. The Authors retrospectively evaluated 17 patients accounting for 21 vascular lesions of the upper extremities (16 arterial and 5 venous injuries). Age, sex, modality of trauma, site of the vascular lesions and of the associated injuries, diagnostic procedures at the admission, ischemic time, arterial and venous repair performed were analyzed. The over all peri-operative mortality was 5.8%. Of the 16 arterial injuries long-term reconstruction viability was obtained in 15 patients (93.7%). In all cases limb salvage was obtained. In 3 patients invalidating functional defects due to associated injuries of the major brachial plexus were observed. The Authors believe that associated nervous lesions are the main factor determining invalidating residual disability. In this series ischemic time, technique of vascular repair performed, associated skeletal injuries didn't influence the functional outcome of the reconstruction.

[Splenectomy in immune thrombocytopenia and other hematological diseases]. / La splenectomia nelle trombocitopenie immuni ed in altre malattie ematologiche.

The Authors report a retrospective study of 74 splenectomies performed for hematologic diseases. The role of splenectomy has changed over recent years with increased indications for immune thrombocytopenic purpura (ITP). The aim of this study was to assess indications to surgery in relation to clinical presentation with typical hemorrhagic features or severe thrombocytopenia only; interval between onset of symptoms and splenectomy; failure of medical management and complications from steroid administration; scintigraphic studies predictive of response to splenectomy and preoperative treatment in patients with severe thrombocytopenia were also studied. The Authors reported response rates to splenectomy of 84% without mortality and only 11% of postoperative complications. These results encouraged to surgery for treatment of those patients with severe thrombocytopenia, who fail to obtain remission or develop serious complications after medical therapy. The splenectomy cured severe thrombocytopenia also in some patients with acquired immunodeficiency (HIV+). Moreover the Authors discuss the indications in patients with chronic lymphatic leukaemia and lymphoma diseases. In selected patients the splenectomy has the potential to relieve symptoms due to splenomegaly, correct cytopenias, specify hystological diagnosis and modify the disease course of malignant lymphomas. In fact splenomegaly sometimes complicated the course of malignant lymphomas because of hematologic abnormalities that are inconsistent with active chemotherapy.

Solitary metachronous splenic metastases: an evaluation of surgical treatment.

Splenic metastases occurring after primary tumor removal and apparently solitary have been documented only recently in Literature. They are, most of the times, clinically asymptomatic and their presence is casually determined by ultrasonographic follow-up in subjects otherwise in good conditions. The belief that splenic metastases occur only in disseminated cancer is today no longer accepted. Some Authors consider solitary splenic metachronous metastases eligible for surgical treatment as well as pulmonary or hepatic metastases. In the case presented, surgery was required due to abscess formation of a splenic metastasis, which was not responding to chemotherapy. Our experience, like others reported in Literature, verified a long-term post-operative survival in spite of limited disease-free time. Surgical treatment by splenectomy can be indicated in selected patients, considering that chemotherapy has been proved to be ineffective in the treatment of splenic metastases.

Cisplatin, high dose folinic acid and 5-fluorouracil in squamous cell carcinoma of the esophagus. A pilot study.

We treated 20 patients with squamous cell carcinoma of the esophagus with the following regimen: cisplatin = 100 mg/m2 i.v. day 1, HDFA = 200 mg/m2 i.v. day 1 to 5, 5-fluorouracil = 370 mg/m2 i.v. day 1 to 5 repeated every 28 days. Among the 17 evaluable patients, 4 (23%) had a partial remission, 6 had stable disease while 7 progressed. The median survival for all patients was 6+ months. Grade III or IV toxicity included 2 patients with grade III leukopenia, 1 with grade III thrombocytopenia, 1 patient with grade IV and 3 patients with grade III oral mucositis, 3 patients with grade III diarrhea. The regimen did not seem particularly active in the treatment of squamous cell carcinoma of the esophagus and had manageable but substantial toxicity.
