[Isolated metastasis of squamous cell carcinoma of the esophagus in the terminal ileum. Report of a case].

Squamous cell carcinoma of the esophagus, with isolated metastasis to the terminal ileum, is a rare finding. Only 18 of such cases have been reported in the medical literature, all of them found at necropsies. The accurate examination of the abdominal cavity, after performing a gastrostomy, showed a neoplastic lesion in the terminal ileum, which was then resected. The histopathological examination revealed the metastatic nature of the lesion. The authors emphasize the importance of a complete and accurate revision of the abdominal cavity on patients with esophagus squamous cell carcinoma.

[Cystic dilatation of the common bile duct in adults. Report of 4 cases].

The authors report four cases of patients who presented congenital choledochal cysts. They discuss the incidence, classification, pathophysiology, diagnosis, clinical presentation and current treatment based in their own experiences and in a review of the literature on the subject.

[New tactical maneuver for hemostasis of parenchymal organs].

The authors report a new surgical procedure destined to realize the hemostasis suture of parenchymatous organs, mainly spleen and liver. The suture is done with needle and absorbable suture material appropriate for the lesion and small hemostatic gere plates. The main qualities of these procedure are the passage of the suture wire in the easiest direction for the surgeon and the confection of these manoeuvre out of abdominal cavity. This procedure was applicated, until now, in nine cases with fully success.

[Bilio-digestive fistulas].

The authors report upon 5 cases of biliary-enteric fistulas, all of them detected preoperatively in a General Surgery Service during a relatively short period of time (6 months). Two cholecysto-duodenal and one cholecysto-ileal fistula were complications of a pre-existent cholelithiasis. A choledocho-duodenal fistula was caused by a penetrating peptic ulcer and a choledocho-colonic fistula was a iatrogenic traumatic one. The review of the literature demonstrates generally a lower incidence of this pathology in different surgical centers, one or two cases a year. More than 50 per cent of the biliary-enteric fistulas were unexpectedly found during operations on the biliary tract or stomach. This forces the surgeon to change his programmed surgical procedure without adequate preoperative preparation. The consequence is a higher morbidity rate in such operations. The continuing refinement of diagnostical procedures have led to a progressive and more frequent preoperative assessment of these fistulas. Adequate diagnostic methods and surgical procedures adopted in different cases of biliary enteric fistulas are discussed, emphasizing the good results obtained and the lower morbidity.

[Splanchnic portal circulation (enhancement of radiologic image intensity and of visibility of collateral branches with prostaglandin E1)].

The authors present the results of a comparative study of mesenterico-portographies with and without the use of Prostaglandin E1 (PGE1) injected intrarterially into the superior mesenteric artery as an adjunct to the radiographic procedure. Twenty eight patients, with varied hepatic and biliopancreatic ailments, referred to the Radiologic Department for angiographic appraisal of the splanchnic circulation were studied. Two series of radiographies were realized after catheterization of the superior mesenteric artery: a first after the injection of the contrast only and a second after the injection of 50 micrograms of PGE1 as a bolus prior the contrast means. The difference in opacification of the various segments of the portal system and the lapse of time necessary to attain the maximum radiographic density were appraised. They observed that, with the use of PGE1 was attained a regular, intense and swift opacification of the superior mesenteric vein, portal vein and intrahepatic branches in all patients that had those segments previous and/or hepatotropic circulation. There was a significative reduction in the lapse of time necessary to attain the maximum opacification. Also they observed, with the use of the PGE1, the opacification of collateral branches of the portal system in more patients and intensification in those that were previously opacified. Because of the good results attained with the use of the PGE1, its transitory pharmacologic action and absence of collateral reactions with the dose used, they recommend its regular use when this investigation is performed.

[Atherosclerotic stenosis of the main branches of abdominal aorta. (Prevalence in patients with lower limb occlusive vascular disease)].

The authors present the radiographical study of the aortographies of 100 consecutive patients with symptomatic atherosclerotic ischemia of the lower limbs in whom were appraised the stenosis of the celiac trunk, superior mesenteric artery, renal arteries and the presence of the inferior mesenteric artery. The parameters observed were: age, sex, solitary and concomitant stenosis. Seven patients were excluded: six because of arteritis and one because could not be analyzed. Sixty four (68.81%) of the remaining 93 patients had important stenosis (> 30%) of one or more branches of the abdominal aorta, which had a steep raise in number from the 60 decade on. There was no difference regarding to the sex of the patients. The more frequently found solitary stenosis was that of the celiac trunk (16-16.1%) followed by the renal (13-13.0%) and in the concomitant was that of the celiac trunk/renal artery (8-8.6%) and celiac trunk/superior mesenteric artery (5-5.3%). They conclude that in spite of the great number of stenosis of the branches of the abdominal aorta in this kind of patients, there was a low incidence of the concomitant stenosis of the celiac trank/superior mesenteric artery, being difficult to characterize radiologically the digestive ischemic syndrome. They point out that this highly selected group of patients, because of their basic disease, should be more extensively studied in order to identify the results of those vascular stenosis on their digestive tract and orient its eventual treatment.
