Patient information for liver biopsy: impact of a video movie.

AIMS: The information given to patients before a medical procedure is usually delivered verbally and in the form of a written document. Viewing a video movie about the procedure might be helpful in improving the quality of patient information and thus contributed to reduce patient anxiety. The aim of this prospective study on the methods used to deliver information to patients scheduled for liver biopsy was to determine, in comparison with standard information delivery, the impact on anxiety and understanding of additional information provided by a video movie. METHODS: Patients included in this study were scheduled for liver biopsy. Three days before the procedure, a physician informed the patients about liver biopsy and gave them a written information document. After this standard information delivery, the patients were randomly assigned to two groups, to view or not a video movie illustrating liver biopsy and recalling the information provided in the information document. Anxiety was measured after the information visit and just before the biopsy procedure using Spielberger's self-administered STAI-Y questionnaire. Patient understanding of and satisfaction with the information received were evaluated respectively before and after the procedure. RESULTS: Among the 67 patients retained for analysis, 33 viewed the information video and 34 did not. The level of anxiety measured at the information visit and before liver biopsy was similar in the two groups (38.8 and 37.4 with video versus 38.9 and 40.1 without video). The patients had an excellent understanding of the information received (12.3/14 with video; 12.7/14 without video) and were well satisfied with the information received. CONCLUSION: The patients understood and were well satisfied with the information received about liver biopsy. Complementary information in the form of a video movie had no effect on patient anxiety.

Are drugs a risk factor of post-ERCP pancreatitis?

BACKGROUND: Pancreatitis is the most severe complication of ERCP. The aim of this study was to assess whether the use of potentially pancreatotoxic drugs is a risk factor for post-ERCP pancreatitis. METHODS: Risk factors for post-ERCP pancreatitis and all drugs taken during the month before ERCP were recorded retrospectively in a database. Patients with other causes of acute pancreatitis or chronic pancreatitis were excluded from the analysis. Post-ERCP pancreatitis was defined as abdominal pain and/or vomiting associated with amylase/lipase plasma levels equal to or greater than twice the upper normal value. RESULTS: A total of 173 patients (95 men, 78 women; mean age, 68 [16] years) were included. Post-ERCP pancreatitis occurred in 31 patients (18%). Several risk factors were identified in a multivariate analysis: difficulty in cannulation (p<0.001), endoscopic sphincterotomy (p<0.005), and female gender (p=0.02). Having taken potent pancreatotoxic drugs increased the occurrence of post-ERCP pancreatitis: odds ratio 3.7: 95% confidence intervals [1.1,12.4], p=0.04. CONCLUSIONS: Use of pancreatotoxic drugs before or during ERCP significantly increased the risk of post-ERCP pancreatitis. Thus, discontinuation of the use of such drugs before ERCP seems justified whenever possible.
