Leiomyoblastoma of the stomach: endoscopic treatment.

Since 1960, about 250 cases of leiomyoblastoma of the stomach have been reported. The diagnosis was always made after surgical resection or necropsy. We report the first case of gastric leiomyoblastoma successfully treated by endoscopic resection, in a 76-year-old woman presenting with upper gastrointestinal bleeding. This therapeutic procedure would seem to be the one of choice, in view of the age of the patient, the limited size and the pedunculated form of the tumor. Endoscopic follow-up should be instituted since local recurrence of the tumor and distal metastases have been reported.

Prolonged total parenteral nutrition in a pregnant woman with acute pancreatitis.

During the 22nd week of her first pregnancy, a 28-year-old woman developed an attack of acute pancreatitis 10 months after pancreatoduodenectomy for chronic pancreatitis of alcoholic origin. She received total parenteral nutrition without complications for 83 days until the cesarean delivery of a child weighing 2,120 g. During that time, clinical, biological, and echographic signs of pancreatitis progressively disappeared. The favorable outcome for both mother and fetus suggests that prolonged TPN may be a useful measure in the management of severe digestive disease occurring during pregnancy.

Spontaneous Yersinia enterocolitica peritonitis in idiopathic hemochromatosis.

We report a case of spontaneous Yersinia enterocolitica peritonitis revealing idiopathic hemochromatosis in a 62-yr-old man with fever and diarrhea. Blood and stool cultures were repeatedly negative, but Yersinia enterocolitica serotype 9 was isolated from ascitic fluid and serum agglutinins against this organism were positive at a dilution of 1:2560. Moreover, a serum Brucella agglutination test was positive at a dilution of 1:320. Antibiotic therapy with doxycycline led to a rapid clinical improvement, with disappearance of the organism in the ascitic fluid. This case suggests that Yersinia enterocolitica infection must be suspected in any febrile abdominal syndrome occurring in patients with iron overload, such as thalassemia major or idiopathic hemochromatosis.

Inferior mesenteric arteriovenous fistula associated with portal hypertension and acute ischemic colitis. Successful occlusion by intraarterial embolization with steel coils.

The authors report a case of postoperative arteriovenous fistula between the inferior mesenteric vessels. This fistula was revealed by portal hypertension, with bleeding esophageal varices, ascites, and encephalopathy, and by acute ischemic colitis. Histologic examination of the liver was normal. All of the symptoms disappeared after transcatheter embolization of the fistula with stainless steel coils. This case report favors the reality of the so-called "forward" portal hypertension and suggests that inferior mesenteric arteriovenous fistula might be a factor predisposing to nonocclusive ischemic colitis.

[Acute hepatitis due to carbamazepine (Tegretol). Study of a case and review of the literature].

The case of a 28-year-old epileptic woman, treated for 3 months with carbamazepine and who developed jaundice, fever and exfoliative dermatitis is reported. Biological investigations showed an increase in the activity of serum transaminases and alkaline phosphatases as well as in the blood eosinophilic count. Liver biopsy revealed centrolobular necrosis and cholestasis with portal inflammatory infiltrate. Drug challenge was followed by the rapid recurrence of clinical and biological signs. The definitive outcome was favorable. The analysis of the 12 previously published cases, and particularly the frequency of granulomatous hepatitis, suggests an immunoallergic mechanism for the development of carbamazepine hepatitis.

[Gallbladder atony and celiac disease in adults. Radiographic and echographic study of 15 cases].

Gallbladder emptying was evaluated in 15 adult celiac disease patients by oral cholecystography or ultrasonography, after fatty meal or cholecystokinin stimulation. Gallbladder inertia was found in 13 cases. Our study agrees with previously reported results; however it is the first one in which this abnormality was demonstrated by ultrasonography. Our findings may suggest that gallbladder inertia is due to duodenal release of an inactive endogenous cholecystokinin. Control studies demonstrates that gallbladder inertia is reversible after gluten-free diet, recurs with relapse, and thus represents a true celiac disease sign, and not an associated condition. Finally, our cases suggest that gallbladder inertia may be radiologically evident before clinical features of malabsorption become apparent. Awareness of this possibility may persuade the radiologist to research in this condition an occult celiac disease.

Metronidazole in prevention of cholestasis associated with total parenteral nutrition.

The effect of metronidazole on liver function tests was studied in patients given total parenteral nutrition (TPN) for an acute attack of Crohn's disease. In those receiving TPN and metronidazole, serum activities of alkaline phosphatase and gamma-glutamyl-transferase decreased or remained normal after 30 days of TPN. In contrast, serum activities of these enzymes increased significantly after 30 days of TPN alone. These results suggest that intrahepatic cholestasis associated with TPN may be related to intestinal overgrowth of anaerobic bacteria.

Bleeding cecal typhoid ulcer. Value of emergency angiography for selective surgical hemostasis.

A case of bleeding cecal typhoid ulcer in a 22-year-old patient demonstrated by superior mesenteric arteriography is described. An attempt to stop hemorrhage using intraarterial vasopressin infusion, failed. However, arteriography proved helpful in locating the bleeding site, and in permitting conservative surgery, namely cecal ulcer suture to achieve hemostasis. On the basis of this case and a review of the literature, management of complicating hemorrhage resulting from typhoid fever is discussed, with particular reference to radiological procedures.

[Nodular regenerative hyperplasia of the liver. Study of 15 cases and review of the literature].

The authors report 15 cases of nodular regenerative hyperplasia (NRH) of the liver observed in 10 women and 5 men during a 9 year period. Gastrointestinal bleeding due to ruptured esophageal varices revealed the liver disease in 11 cases. Hepatomegaly and splenomegaly were noted in 9 cases and ascites in 7. Anicteric cholestasis was demonstrated in 10 cases. Another disease, e. g. myelofibrosis and monoclonal gammapathy, was present in 11 patients. In 10 patients, portal diversion was performed; outcome being favorable with a follow-up of one to six years. The analysis of these cases and of the 113 previously published reports calls for the following comments: 1) In most cases, NRH is characterized by small-sized hepatocytic nodules scattered throughout the entire liver with no surrounding fibrosis; however this histological pattern may vary somewhat, with adjacent normal zones being found adjacent to typical cirrhotic fibrosis; although a precise morphometric study was not performed in our patients, obstruction of the tiny branches of intrahepatic portal veins was not observed. 2) Histological diagnosis of NRH is difficult and in most cases requires surgical biopsy specimens and specific coloration of the reticulin network. 3) NRH must be considered as a new cause of intrahepatic (sinusoidal or presinusoidal) portal hypertension and/or of chronic anicteric cholestasis. 4) A number of various conditions may be associated with NRH, the most frequent being Felty's syndrome and myeloproliferative disorders. 5) The pathogenesis of NRH remains unknown. 6) Portal diversion generally has a favorable outcome in this disease.

[Upper esophageal varices. Study of 6 cases and review of the literature].

Distal esophageal varices are most frequently associated with portal hypertension, while varices of the upper esophagus are occasionally observed in patients with vena caval obstruction. One hundred and nineteen cases of upper esophageal varices (downhill varices) have been reported in the literature. We report 6 cases (4 men and 2 women), with vena caval obstruction. Upper gastrointestinal hemorrhage occurred in one patient. Endoscopy showed varices in the proximal third of the esophagus in 5 patients and in the proximal half of the esophagus in the other patient. Superior vena cavogram demonstrated total or partial occlusion of the vena cava in 6 cases, with opacification of the right azygos vein in 4 cases and thrombosis of this vein in one case. Superior vena caval obstruction was secondary to malignant lymphoma in 2 cases, to malignant thymoma in 2 cases, to malignant thyroid tumor in one case and to anaplastic bronchogenic carcinoma in one case. Clinical symptoms of vena caval obstruction are present in 91.4 p. 100 of the cases in the literature. Upper gastrointestinal hemorrhage are observed in 7.6 p. 100 of cases. It is generally agreed that the predominant factors involved in the determination of the downward extension of varices along the esophagus are the level of superior vena caval obstruction and its duration. Because of the risk of digestive hemorrhage and of the topographic meaning of the degree of extension, upper esophageal varices should be routinely searched in patients with vena caval hypertension.

Mucosal bridges of the upper esophagus after radiotherapy for Hodgkin's disease.

A 47-yr-old man presented with dysphagia 4 yr after mediastinal radiotherapy for Hodgkin's disease. X-ray series, fiberoptic endoscopy, and computerized transverse tomography showed mucosal bridges in the upper esophagus. Histologically, these bridges were constituted from normal epithelium overlying a chronic inflammatory lamina propria, without evidence of Hodgkin's disease recurrence or of squamous cell carcinoma. Swallowing was improved by endoscopic electrocoagulation and Eder-Puestow dilatations. Several arguments favor the hypothesis that these mucosal bridges were the late sequelae of radiation esophagitis.
