[Solitary small bowel metastasis after resection of bile duct carcinoma].

Small bowel solitary metastases are a very rare occurrence and are more frequently recognized only in the presence of a severe complication, such as intestinal hemorrhage or occlusion. We report the case of a 75 year-old man who was admitted with a recent history of mechanical ileus developed one year after the surgical removal of an endoscopically intubated carcinoma of the extrahepatic biliary tree (pT3 pN0 Mx). A solitary metastasis of the small bowel, 30 cm from the ileo-cecal valve, was excised during the emergency laparotomy and a side-to-side anastomosis was performed to reconstruct the intestinal continuity. Patient was, thereafter, discharged in the 9th postoperative day. Local recurrence and intrabdominal dissemination are often observed in patients treated for bilio-pancreatic carcinoma. Preoperative invasive (ERCP, FNA, PTBD, etc.) diagnostic procedures and surgical tumor manipulation are associated with a greater risk of metastasis implantation and intraabdominal dissemination. In accordance to the literature, the authors propose, in cases with resectable bilio-pancreatic neoplasms, the use of standard external low dose radiotherapy prior to any invasive diagnostic procedure and/or surgical removal.

[EEG and biochemical considerations on 40 cirrhotic patients surgically treated by portacaval anastomosis or mesenterico-caval bypass].

Starting from biochemical hypotheses on hepatic encephalopathy, which presuppose at the basis of this disease first of all some modifications of the plasmatic values of octopamine, ammonia, serotonin and of particular aromatic aminoacids, the Authors compared the levels of ammoniemia and of octopaminemia with eegraphic data, in two groups of cirrhotic patients, operated of porto-cava anastomosis (16 patients) ad of mesenterico-cava by-pass (24 patients). All this in order to value if there are significant correlations between these values and the cerebral damage and also if there are differences between the two types of operation. Attained data show a good correlation between neuropsychiatric symptomatology and importance of the cerebral damage noticeable at the E.E.G. As to the possible correlations existing between biochemical data and E.E.G., while as to plasmatic octopamine no significant modifications were found, as to ammoniemia, highest values correspond to findings of greater cerebral compromission. Moreover, it seems that between the two types of operations, the mesenterico-cava by-pass is the one that allows a better clinical and eegraphic evolution.

[Unusual location of hydatid cysts: clinical and therapeutic aspects].

Among patients treated for hydatidosis, unusual sites are observed in 5-30% of cases, with highest rates in endemic areas; on these basis during the diagnostic work up of masses arising from peritoneum, spleen, mediastinum, kidney and muscle, this possibility should be always taken into account. In fact, only a preoperative diagnosis allows a correct therapeutic approach, especially when synchronous lesions coexist. In this paper the Authors report their experience in the treatment of 66 (5.2%) hydatid cysts developed in unusual sites, out of 1275 patients treated for hydatidosis from 1949 to 1993. They discuss the main pathogenetic and clinical features as well as the therapeutic management of these atypical lesions.

[Retroperitoneal schwannoma: report of a clinical case and review of the literature].

The retroperitoneal localization of a schwannoma or neurilemmoma undoubtedly represents an unusual occurrence (0.5-0.7% of all sites); this data, together with the absence of a typical clinical picture and the lack of peculiar instrumental signs, make a preoperative diagnosis of this lesion really hard to ascertain. In this paper, on the basis of a case report successfully treated, the Authors review the literature analysing current diagnostic and therapeutic work up, mainly emphasizing controversies in determining a proper preoperative diagnosis among all retroperitoneal tumours.

[Localized fibroma: a rare tumor of pleural origin].

Localized fibroma represents a rare entity arising from the pleura. Currently its histogenesis and clinical behaviour are still controversial. A case of a 64-year-old male is here presented; clinical and histopathological features are then discussed on the basis of a review of the Literature. At present, an en-bloc resection of the tumor, including wide margins of the surrounding lung tissue, seems to be the most appropriate surgical choice.
