[The echographic characterization of pancreatic pseudocysts].

The diagnosis of pancreatic pseudocyst is still troublesome. In 95% of cases a correct diagnostic evaluation can be achieved by means of ECT or CT scan, ERCP, NMR, EE etc.. ECT and CT scan in particular are the most specific and accurate techniques. ECT scan is currently the up-to-date method for initial diagnosis and continuous monitoring of the lesion. In fact, very interesting real-time data and exact features of the wall of the cysts may be obtained by ECT scanning also suggesting the best therapeutic choice.

[Evaluation of the splenic function in patients with abdominal injuries undergoing splenectomy with autograft].

Splenectomy, required for splenic injuries in which conservative management is unsuitable, causes a fall of the immunological defenses, increasing the risk of sepsis. Immunological functions of the spleen can be maintained by autotransplant of splenic tissue. This is confirmed in our experience by a comparative study of haematological, immunological and scintigraphic features in 14 patients. Autotransplantation was performed in 8 cases, while the remaining 6 cases were treated with simple splenectomy.

[Reconstruction of the thoracic wall using a Marlex sandwich. Presentation of a clinical case].

The case of a 78-year-old male with a large, firm, not tender mass of the left anterolateral region of the chest is reported. Previously he had been treated with cyproterone acetate for a year, being affected by a locally unresectable prostate carcinoma. At CT-scan of the chest mass appeared solid, extending to the pleural cavity with compression of the lung and erosion of third to fifth rib. Operation consisted in complete removal of the mass with "en bloc" resection of involved ribs. Chest wall was reconstructed by means of a Marlex mesh sandwich. Histology revealed a carcinoma, probably originating from the breast. The role of antiandrogenic chemotherapy in the development of the tumor and the use of plastic mesh for chest wall defects are discussed.

Recurrent primary hydatidosis of sartorius muscle. Case report.

A case of recurrent primary hydatidosis of sartorius muscle is reported. Initially an intact cyst was enucleated and the cavity irrigated with hypertonic saline, but 41 months later the cyst had recurred. Cysto-pericystectomy and saline irrigation were now performed, followed by mebendazole for 21 days. The patient is recurrence-free after 19 months.

[Pre- and postoperative external biliary drainage in patients with obstructive jaundice caused by neoplasm of the pancreatic head].

The external biliary drainage in severe jaundice secondary to pancreatic carcinoma acts differently in pre, intra, and postoperative period. In the preoperative period the drainage enables to lower the direct bilirubinemia and the intrahepatic biliary stasis and consequently the complications linked to the impaired hepatic and renal function. During the operation the catheter acts as a guide in performing the biliodigestive anastomosis. In the postoperative period the external drainage of most of daily biliary secretion protects the biliodigestive anastomosis during the postoperative paralytic ileus, and prevents the fistula development along the pancreatic jejunal anastomosis.

[Reoperations in lung surgery].

A second thoracotomy in patients who have undergone previous chest surgery can be performed soon or immediately after the first operation and is usually aimed at resolving severe or even life-threatening postoperative complications. Late reoperations, on the other hand, are either performed to resolve complications of previous surgery or to remove second primary lung tumors (SPLCs) or metastases. The most exacting reoperation in this context is completion pneumonectomy, which is particularly indicated in the case of failure of the residual lobe to re-expand after primary surgery; it is also used for--rarely occurring--fistulas of the lobar bronchi and for new ipsilateral primary lung tumors. This type of surgery is technically complicated and has been associated, in our experience and that of others, with a certain mortality. Technically less difficult is a second ipsilateral thoracotomy for exploratory purposes or minor parenchymal resection, and the same is true of contralateral lobar or sublobar resections. Lastly, Abruzzini's operation, for fistulas of the primary bronchus, is relatively complicated but often leads to good results; we have performed 15 such operations with only one death occurring due to acute myocardial infarction.

[Photodynamic therapy in cardiac and vascular surgery].

One of the major drawbacks to therapeutic cardiovascular intervention is intimal hyperplasia and constrictive remodeling, which result in vascular restenosis. Neointimal hyperplasia is characterized by proliferation and migration of smooth muscle cells. These cells also produce new extracellular matrix, leading to narrowing of vessels. Photodynamic therapy (PDT) represents one of the most promising approaches to the inhibition of intimal hyperplasia. PDT requires the interaction among 3 factors: a source of light, usually a laser, a photosensitizer and oxygen. When the inert photosensitizer absorbs light of a specific wavelength, it is activated to an excited triplet state, generating reactive oxygen species. These free radicals are able to induce apoptosis of the smooth muscle cells that had absorbed the photosensitizer; they also induce changes in the extracellular matrix, reducing cell migration. Because of continued success of PDT in inhibiting intimal hyperplasia in experimental animal models, it is now being tested in clinical trials for vascular diseases. PDT offers many advantages to the surgeon since it can act on numerous factors responsible for vascular lesions. In the future PDT could be used in helping to overcome the inherent failures associated to vascular reconstruction. This treatment modality is emerging as an encouraging therapeutic option, either alone or as an adjunct to conventional treatment. However, more detailed clinical investigation are necessary to determine its full potential.

Adenocarcinoma and epidermoid carcinoma of the lung in the elderly.

Primary lung carcinoma, in the elderly, presents some interesting epidemiologic and clinical characteristics. The authors, after reviewing the international literature, stress the differences of behavior and incidence of epidermoid carcinoma and adenocarcinoma occurring in elderly patients as compared to those found in younger patients. They report their experience which is similar to that reported in the medical literature.

[A geriatric case of colonic angiodysplasia].

A case of colic angiodysplasia in an elderly patient affected by chronic renal failure is discussed. Different methods suitable for management of these vascular ectasies are briefly reported. Prominent role of colonoscopy in the diagnosis of such disease is emphasized.
