[Propranolol prevention of hemorrhagic recurrence caused by rupture of esophageal varices: worsened prognosis in ascites and jaundice].

Between October 1981 and December 1983, 46 consecutive unselected cirrhotic patients who had been admitted for variceal hemorrhage were assigned to propranolol for the prevention of variceal rebleeding and followed for a mean period of 13.3 months (ranges: 1 day, 45 months). At the time of inclusion, 87 p. 100 of patients had alcoholic cirrhosis: ascites was present in 43 p. 100, jaundice in 43 p. 100 and encephalopathy in 33 p. 100 of cases. The goal of this retrospective study was to assess the effectiveness of propranolol in these unselected patients and to determine variables associated with a high rebleeding rate. Twenty-four patients (52 p. 100) rebled from esophageal varices within a mean time of 8.2 months (range: 6 days, 39 months) and 12 of these patients died. The percentage of patients who rebled from varices was 27 p. 100 at 6 months, 43 p. 100 at 1 year, 52 p. 100 at 18 months. Patients with ascites at the time of inclusion were 3.5 times more likely to rebleed than patients without ascites (p = 0.007). Patients with jaundice (total bilirubin greater than or equal to 50 mumol/l) were 3.1 times more likely to rebleed than patients without jaundice (p = 0.01). One year after the beginning of this treatment, the probability of rebleeding was 19 p. 100 in the 17 Pugh-Child class A cirrhotic patients, 60 p. 100 in the 15 class B patients, 55 p. 100 in the 14 class C patients. Neither proper acceptance in taking propranolol nor alcohol withdrawal were associated with significantly modified risks of rebleeding in these unselected alcoholic patients.

[Results of endoscopic sphincterotomy in common bile duct lithiasis].

Endoscopic sphincterotomy (ES) was attempted in 409 patients with common bile duct stone(s) (CBDS). The mean age of patients was 72.0 +/- 0.8 years (m +/- SEM); 47 p. 100 presented risk factors; 57 p.100 had previously been cholecystectomized while 43 p. 100 had not. On an average, patients in the former group were older (80 +/- 0.7 years) than in the latter 65.4 +/- 1.0 years, p less than 0.001). The procedure was successful in 98 p. 100 of the patients, after a standard ES in 78.5 p. 100 or after different technical artifices in 21.5 p. 100. The vacuity of the CBD was obtained in 96.5 p. 100 of the cases. During the first month after the ES, 13 p. 100 of the patients had complications and 4 p. 100 died; 37 complications (9 p. 100) were related to the ES and were responsible for death in 4 patients: 18 episodes of bleeding at the site of ES, 7 acute pancreatitis, 6 cholangitis, 4 retroperitoneal perforations and 2 other complications. The occurrence of these complications was closely related to the technique of ES being more frequent after technical artifices than after a standard ES (p less than 0.001). On the other hand, these complications occurred independently of the age of patients or of previous cholecystectomy. Seventeen complications (4 p. 100) did not depend directly on ES and were responsible for death in 14 patients (3 p. 100): pneumopathy, pulmonary embolism.(ABSTRACT TRUNCATED AT 250 WORDS)

[Endoscopy in tumors of the Oddi region. Diagnostic and therapeutic possibilities].

Between 1976 and 1983, 92 patients (mean age: 70 years) with ampullary or periampullary tumors, were evaluated by endoscopic procedures. The ampulla appeared malignant in 66 p. 100 of cases, enlarged but not obviously malignant in 15 p. 100 and normal in 18 p. 100. In one case, a tight duodenal stenosis prevented the endoscopist from seeing the ampulla. ERCP was performed in 70 patients and the common bile duct was opacified in 63 cases; it was dilated in 60 patients. Two types of tumors could be distinguished: 67 p. 100 grew within the duodenum and were seen by duodenoscopy and 33 p. 100 grew outside the duodenum and ERCP opacified a dilated common bile duct above a stenotic region; in these cases, diagnosis was established by biopsies performed through the ampulla, after endoscopic sphincterotomy (EST). Biopsy specimens were obtained in 67 p. 100 of cases and yielded a diagnosis of adenocarcinoma in 59 p. 100, questionable carcinoma in 15 p. 100, benign tumor in 16 p. 100 and normal mucosa in 10 p. 100. In 8 patients with the preoperative diagnosis of non-malignant tumor, operative biopsies finally revealed carcinoma in 7. EST or infundibulotomy was performed in 42 patients with 2 deaths from hemorrhage and cholangitis. Twenty-three patients received only EST as final treatment with complete disappearance of jaundice and/or cholangitis in 70 p. 100. Our results confirm the efficacy of duodenoscopy, ERCP and EST in the diagnosis and sometimes in the treatment of ampullary and periampullary tumors.

[Chronic alcoholic pancreatitis: relation of pain to withdrawal and pancreatic surgery].

A group of 73 patients suffering from painful alcoholic, chronic pancreatitis, hospitalized from 1971 to 1981, has been analyzed retrospectively. The aim was to assess the effects of alcohol withdrawal and pancreatic surgery on the course of pancreatic pain. The mean number of years during which the patients complained of pain was 3.5 +/- 0.5 (m +/- SEM). At the end of follow-up, 70 p. 100 of the patients did no longer suffer, alcohol withdrawal was obtained in 45 p. 100 and surgery had been performed in 41 p. 100. Continued alcohol abuse did not prevent pain relief: 60 p. 100 of patients continuing to drink at the end of follow-up, did not suffer any longer. One year after pancreatic surgery, pain relief was more frequent, if alcohol abstinence had been obtained before surgery (p less than 0.01). Among the 53 patients followed up to 5 years after the start of pain: a) the cumulative actuarial probability of disappearance of pain was 17 p. 100 at 2 years, 52 p. 100 at 5 years, 62 p. 100 at 8 years after the start of pain. Alcohol abstinence and surgery were observed during the first five years of pain; b) the mean number of years of pain was lower among the patients who became abstinent early (less than 4 years after the beginning of pain) than among those who did not (p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
