Does the somatostatin analogue octreotide protect against ERCP induced pancreatitis?

This study evaluates the effect of the long acting somatostatin analogue octreotide on biochemical and clinical parameters of endoscopic retrograde cholangiopancreatography (ERCP) induced pancreatitis. Altogether 245 patients were randomised to receive either octreotide or isotonic saline. Octreotide (100 micrograms) was administered intravenously five minutes before ERCP and subcutaneously 45 minutes after ERCP. There were no significant differences in the median serum amylase and lipase activities at baseline, eight, and 24 hours after ERCP. Five patients (2%) developed clinical pancreatitis--three in the octreotide and two in the placebo groups. Excluding patients who developed pancreatitis, 43 (18%) developed abdominal pain after ERCP--21 in the octreotide and 23 in the placebo groups. There were no significant differences in the median serum amylase and lipase values between the treatment groups. None of the 52 patients who had therapeutic interventions developed pancreatitis. This study suggests that octreotide may not protect against ERCP induced pancreatitis.

[The variability of arterial pressure measured by oscillometric methods in premature newborn infants].

The variability of blood pressure measured by oscillometry and the validity of this technique were studied in premature infants. Thirty premature babies whose postnatal age was six days or more had their blood pressure measured 11 times over a twenty-minute period for three consecutive days. Movements were found to have a very substantial influence on results that could not be reliably compared with values obtained invasively. No consistent pattern of variations of oscillometric results obtained during the eleven measurements of use for recommending a specific measurement time was found. Diastolic blood pressure fell gradually over the three-day study period. The most reliable of the eleven daily values was the lowest value for which good correlations were found between the three study days; this lowest value was not influenced by neonatal or postnatal factors.

[Cholecystocolic fistula: from symptoms to diagnosis].

We report 2 patients with a cholecystocolic fistula in whom diametrically opposite symptoms (isolated steator-rhea, jaundice and fever) were responsible for important clinical difficulties. These fistulae are far less common than cholecysto-duodenal fistulae. Endoscopic retrograde cholangiography was performed because of abnormal liver tests and led to diagnosis in both cases. Classical aerobilia was absent in both of our cases. Barium enema was disappointing (case n. 1), whereas technetium 99m scintiscan visualized the fistula (case n. 2). Two therapeutic approaches are possible in the case of cholecystocolic fistula. Surgery, usually combining cholecystectomy and extraction of common bile duct stones with the treatment of the fistula, may be performed systematically or in case of failure of sphincterotomy (case n. 1). On the other hand, endoscopical sphincteromy during endoscopic retrograde cholangiography, which, by reducing increased biliary pressure, may be sufficient to achieve spontaneous closure of the fistula in an elderly or high risk patient (case n. 2).

Hepatic intraarterial lipiodol: technique, semiologic patterns, and value for hepatic tumors.

Hepatic intraarterial lipiodol (HIAL) coupled with computed tomography (CT) was used in a homogeneous series of 138 cases. All patients received 10 ml lipiodol emulsion injected by an arterial route; there were no serious complications. Four semiologic patterns were observed. Aside from nodular regenerative hyperplasia occurring in the absence of cirrhosis, HIAL gave no false-positive indications of tumor, as demonstrated by a series of 20 patients with uncomplicated cirrhosis evaluated for over 12 months. Comparison of ultrasonography, CT, angiography, and HIAL coupled with CT for exploration of hepatomas revealed the marked superiority of HIAL/CT for both tumor detection and lesion localization (search for daughter tumors).

[The value of plasma exchange during flare-ups of benign recurrent intrahepatic cholestasis].

Benign recurrent intrahepatic cholestasis (BRIC) or Summerskill's disease is a rare affection characterized by recurrent episodes of cholestasis of no apparent cause, separated by totally asymptomatic remissions. No specific treatment exists for the disease, and plasma exchange (PE) was proposed for disabling episodes affecting the general condition of two patients: one by two sessions of 4 and 13 exchanges during two episodes respectively (mass exchanged 14 and 35.5 l) and the other by 3 exchanges (total exchanged 4.5 l) during one episode. Improvement in clinical symptomatology and shortening of duration of two cholestatic episodes was noted when PE was carried out at an early stage. Bile acids were purified satisfactorily (42 to 52%), 0.15 to 1.17 mmole being extracted at each acute attack. Although difficult to assess in a rare affection such as this, PE appears to contribute to the symptomatic treatment of BRIC acute episodes if performed early enough, shortening their duration by the probable purification of circulating factors that are cholestatogenic as in primary biliary cirrhosis.

Biofiltration in elderly uremic patients.

We treated five elderly patients with conventional hemodialysis (CH) or biofiltration (BF) to establish whether their dialytic tolerance was better. For three patients treatment time was reduced from twelve to nine hours a week; for the other two, treatment time remained unchanged (10.5-12 h/week) because of their high interdialytic weight gain. At the beginning and end of the study, clinical status, biochemical data, nutritional status and acid-base balance (ABB) were checked. Plasma levels of small molecules, potassium and phosphate were unchanged for all patients. All had a lower number of episodes or less severe hypotension and good control of ABB. No patients had metabolic alkalosis or worsened nutritional status. For all patients BF was an efficacious choice compared to CH, giving them good health.

[The CT scan coupled to the injection of lipiodol into the hepatic artery. Preliminary trial].

A preliminary study of CT findings for 13 malignant liver tumors evaluated after intra-arterial hepatic lipiodol injection is presented. Comparison with ultrasound, conventional CT before and after contrast material injection, and arteriography revealed the superiority of intra-arterial lipiodol injection coupled with CT examination for both the detection of hepatomas and disease extension workups, thanks to the detection of small multifocal lesions. There is no lipiodol uptake by the tumor in cases of metastases or cholangiocarcinoma. The same technique can be applied to non-surgery patients for therapeutic hepatic artery injections of an extemporaneous lipiodol emulsion, hydrosoluble contrast materials and oncostatic drugs. A review of over 100 cases in the Japanese literature emphasizes the efficacy of this therapeutic approach.

Diet and retarded growth.

The diets of 36 children below the third centile for height but with no organic disease were compared with the diets of a control group. In most cases retarded growth was associated with a long-continued deficiency in calorie intake. When the diets were reassessed about a year later the shortfall in calorie intake was significantly reduced. This improvement, which tended to be followed by an increase in the rate of growth in height, might have been due to alteration in the child's circumstances or improvement in the family attitudes and feeding habits or both. Advice given at the clinic is thought to have played a part in bringing these changes about.
