Background
In patients with altered upper gastrointestinal anatomy, conventional endoscopic retrograde cholangiography is often not possible and different techniques, like enteroscopy-assisted or percutaneous approaches are required. Aim of this study was to analyze success and complication rates of these techniques in a large collective of patients in the daily clinical practice in a pre-endosonographic biliary drainage era.
Patients and methods
Patients with altered upper gastrointestinal anatomy with biliary interventions between March 1st, 2006, and June 30th, 2014 in four tertiary endoscopic centers in Munich, Germany were retrospectively analyzed.
Results
At least one endoscopic-assisted biliary intervention was successful in 234/411 patients (56.9%)—in 192 patients in the first, in 34 patients in the second and in 8 patients in the third attempt. Success rates for Billroth-II/Whipple-/Roux-en-Y reconstruction were 70.5%/56.7%/49.5%. Complication rates for these reconstructions were 9.3%/6.5%/6.3%, the overall complication rate was 7.1%. Success rates were highest in patients with Billroth-II reconstruction where use of a duodenoscope was possible, complication rates were also highest in this scenario. Success rates were lowest in longer-limb anatomy like Roux-en-Y reconstruction. Percutaneous biliary drainages (PTBD) were inserted 268 times with substantially higher success (90.7%) as well as complication rates (11.6%) compared to the endoscopic approach. Compared to patients treated endoscopically, patients with PTBD had a lower performance status, more severe cholestasis and a significant higher rate of malignant underlying disease.
Conclusion
In patients with altered upper gastrointestinal anatomy, success rates of endoscopic-assisted biliary interventions are lower compared to PTBD. Still, due to the beneficial complication rates of the endoscopic approach, this technique should be preferred whenever possible and in selected patients who still need to be defined in detail, repeated endoscopic attempts are useful to help achieve the desired result.
