- Percutaneous-transhepatic-endoscopic rendezvous procedures (PTE-RVs) offer a high technical success rate (80%) in patients with a previously failed endoscopic retrograde cholangiography, including patients with an altered gastrointestinal tract.
- Significantly fewer complications occur following PTE-RVs than following percutaneous transhepatic cholangiography (PTC) (16.6 vs 26.6%; p = 0.037); thus, PTE-RVs should be preferred over PTC alone in the case of a necessary percutaneous procedure for biliary interventions.

Abstract: Endoscopic retrograde cholangiopancreatography (ERCP) is considered to be the gold standard for diagnosis and interventions in biliopancreatic diseases. However, ERCP in patients with surgically altered anatomy (SAA) appears to be more difficult compared to cases with normal anatomy. Since the production of a balloon enteroscope (BE) for small intestine disorders, BE had also been used for biliopancreatic diseases in patients with SAA. Since the development of BE-assisted ERCP, the outcomes of procedures, such as stone extraction or drainage, have been reported as favorable. Recently, an interventional endoscopic ultrasound (EUS), such as EUS-guided biliary drainage (EUS-BD), has been developed and is available mainly for patients with difficult cases of ERCP. It is a good option for patients with SAA. The effectiveness of interventional EUS for patients with SAA has been reported. Both BE-assisted ERCP and interventional EUS have advantages and disadvantages. The choice of procedure should be individualized to the patient’s condition or the expertise of the endoscopists. The aim of this review article is to discuss recent advances in interventional ERCP and EUS for patients with SAA.

Results: A total of 7445 patients were included for ERCP and 1690 for PTBD. The overall adverse event rate was 8.6% for endoscopic drainage (640 events) and 12.3% for percutaneous biliary drainage (208 events) (P < .001). When analyzed by type of malignant neoplasm, ERCP was associated with a lower rate of adverse events compared with PTBD for pancreatic cancer (2.9% vs 6.2%; odds ratio [OR], 0.46 [95% CI, 0.35-0.61]; P < .001) and cholangiocarcinoma (2.6% vs 4.2% OR, 0.62 [95% CI, 0.35-1.10]; P = .10). For pancreatic cancer, endoscopic procedures were associated with a lower rate of adverse events regardless of the volume of percutaneous procedures performed by a center. For cholangiocarcinoma, centers that performed a low volume of percutaneous biliary drainage procedures were more likely to have adverse events compared with endoscopic procedures performed at the same center (5.7% vs 2.5%; OR, 2.28 [95% CI, 1.02-5.11]; P = .04). In centers that performed a high volume of percutaneous drainage procedures, rates of adverse events were similar to those of endoscopic adverse events (3.5% vs 3.0%; OR, 1.18 [95% CI, 0.53-2.66]; P = .68).
