Outcome of endoscopic sphincterotomy in patients with pain of suspected biliary or papillary origin and inconclusive cholangiography findings

The Role of Endoscopic Biliary Drainage without Sphincterotomy in Gallstone Patients with Cholangitis and Suspected Common Bile Duct Stones Not Detected by Cholangiogram or Intraductal Ultrasonography

Background/Aims

Treatment for cholangitis without common bile duct (CBD) stones has not been established in patients with gallstones. We investigated the usefulness of endoscopic biliary drainage (EBD) without endoscopic sphincterotomy (EST) in patients diagnosed with gallstones and cholangitis without CBD stones by endoscopic retrograde cholangiopancreatography (ERCP) and intraductal ultrasonography (IDUS).

Methods

EBD using 5F plastic stents without EST was performed prospectively in patients with gallstones and cholangitis if CBD stones were not diagnosed by ERCP and IDUS. After ERCP, all patients underwent laparoscopic cholecystectomy. The primary outcomes were clinical and technical success. The secondary outcomes were recurrence rate of biliary events and procedure-related adverse events.

Results

Among 187 patients with gallstones and cholangitis, 27 patients without CBD stones according to ERCP and IDUS received EBD using 5F plastic stents without EST. The stents were maintained in all patients until laparoscopic cholecystectomy, and recurrence of cholangitis was not observed. After cholecystectomy, the stents were removed spontaneously in 12 patients and endoscopically in 15 patients. Recurrence of CBD stones was not detected during the follow-up period (median, 421 days).

Conclusions

EBD using 5F plastic stents without EST may be safe and effective for the management of cholangitis accompanied by gallstones in patients without CBD stones according to ERCP and IDUS.

The Role of Endoscopic Retrograde Cholangiopancreatography in Management of Pancreatic Diseases

Endoscopic retrograde cholangiopancreatography is an effective platform for a variety of therapies in the management of benign and malignant disease of the pancreas. Over the last 50 years, endotherapy has evolved into the first-line therapy in the majority of acute and chronic inflammatory diseases of the pancreas. As this field advances, it is important that gastroenterologists maintain an adequate knowledge of procedure indication, maintain sufficient procedure volume to handle complex pancreatic endotherapy, and understand alternate approaches to pancreatic diseases including medical management, therapy guided by endoscopic ultrasonography, and surgical options.

Does endoscopic sphincterotomy reduce the recurrence rate of cholangitis in patients with cholangitis and suspected of a common bile duct stone not detected by ERCP?

BACKGROUND

It has not been established whether endoscopic sphincterotomy (ES) prevents subsequent cholangitis in patients with cholangitis and with a common bile duct (CBD) stone not documented by ERCP.

OBJECTIVE

The aim of this study was to investigate the role of ES on the recurrence of cholangitis in patients with a high probability of having a CBD stone, not demonstrated by ERCP.

DESIGN AND PATIENTS

A total of 117 patients who were diagnosed as having cholangitis and a high probability of a CBD stone, not detected by ERCP, were retrospectively reviewed. Cumulative recurrence rates of cholangitis were compared for treatments with and without ES.

SETTING

Multicenter, retrospective study.

INTERVENTIONS

ES.

MAIN OUTCOME MEASUREMENTS

Cumulative recurrence of cholangitis after ERCP.

RESULTS

Eighty-three patients underwent ES (ES group) and 34 patients did not (non-ES group). No statistically significant differences between the 2 groups were evident in terms of demographic factors or laboratory findings. The mean (standard deviation) follow-up was 22.1 +/- 17.2 months (range 3-66 months) in the ES group and 23.3 +/- 14.9 months (range 6-84 months) in the non-ES group (P = .72). The cumulative rates of cholangitis were 6.3% (4.8% vs 9.9%) at 1 year, 15.6% (9.2% vs 29.3%) at 3 years, and 19.5% (9.2% vs 52.9%) at 5 years for ES vs non-ES groups, respectively (P = .04). By multivariate analysis, ES reduced cholangitis recurrence, with a hazard ratio of 0.305 (95% CI 0.095-0.975, P = .045).

LIMITATIONS

Retrospective study.

CONCLUSIONS

ES reduced further episodes of cholangitis in patients with an episode of cholangitis and a high probability of choledocholithiasis, despite the lack of a CBD stone seen on ERCP.
