T. Zoepf et al., The relationship between juxtapapillary duodenal diverticula and disordersof the biliopancreatic system: analysis of 350 patients, GASTROIN EN, 54(1), 2001, pp. 56-61
Background: Data concerning the association of juxtapapillary duodenal dive
rticula (JPDD) with biliopancreatic disorders are inconsistent, but an asso
ciation between bile duct stones and JPDD is widely accepted. The aim of th
is study was to investigate the frequency of JPDD and its association with
biliopancreatic disorders in patients undergoing ERCP,
Methods: A retrospective analysis was conducted of 5497 consecutive ERCP pr
ocedures performed in 2925 patients. Matched-pair analysis yielded 350 pair
s of patients with and without JPDD, matched for definite risk criteria suc
h as age, gender, and indication for ERCP.
Result: The incidence of JPDD was 12%, Patients with JPDD were significantl
y older than patients without JPDD (71 vs, 62 years; p < 0.0019) and had a
significantly higher bleeding rate after endoscopic sphincterotomy (8.8% vs
. 4.8%; p = 0.039). The presence of JPDD correlated with gallbladder stones
(29.4% vs, 20.8%; p = 0.039), bile duct stones (46% vs. 33.1%; p < 0.001),
and recurrence of bile duct stones (6.6% vs. 1.4%; p = 0.002). There were
no significant differences in frequency of acute and chronic pancreatitis a
s well as pancreas divisum, After multivariate logistic regression analysis
, technically difficult ERCP, bleeding after endoscopic sphincterotomy, and
bile duct stones remained as independent risk factors.
Conclusion: JPDD appears to be a risk factor for complications of endoscopi
c sphincterotomy and for gallbladder stones, bile duct stones, end their re
currence.
