Endoscopic ultrasound-guided duodenojejunal anastomosis to treat postsurgical Roux-en-Y hepaticojejunostomy stricture: a dream or a reality?

Endoscopic entero-enteral bypass to treat postsurgical benign complications of hepatico-jejunostomy: Update of a 7-year single-center experience

Background and study aims  Since 2014, we have been using a new endoscopic approach to improve management of biliary adverse events (BAEs) after bilio-digestive anastomosis. We provide an update about our experience at 7 years. Patients and methods  Patients with BAEs on hepatico-jejunostomy underwent entero-enteral endoscopic by-pass (EEEB) creation between the duodenal/gastric wall and the biliary jejunal loop. Evaluation of results during our seven-year experience was performed. Results  Eighty consecutive patients (32 patients from Jan 2014 to Dec 2017 and 48 patients from Jan 2018 to Jan 2021) underwent EEEB, which was successful in all but one patient. The cumulative AEs rate was 32 %. Endoscopic retrograde cholangiography (ERC) through the EEEB successfully treated all types of BAEs in these patients. Cumulative disease recurrence was 3.8 % (three patients) and was retreated through the EEEB. Conclusions  The update of our experience with EEEB confirmed that in patients with BAEs after bilio-digestive anastomosis, EEEB allows successful long-term treatment of different BAEs in a tertiary referral center with an acceptable rate of related AEs.

Effectiveness of double-balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography (DBE-ERCP): A multicenter real-world study

BACKGROUND AND AIMS

To investigate the effectiveness of double-balloon enteroscope-assisted retrograde cholangiopancreatography (DBE-ERCP) in patients with gastrointestinal surgically altered anatomy (SAA).

METHODS

From May 2013 to October 2021, all consecutive patients undergoing DBE-ERCP in three gastroenterological referral centers in Northern Italy were enrolled in the study. Patients were assessed regarding their medical history, previous surgery, time from previous surgery to the DBE-ERCP procedure, and the success or failure of DBE-ERCP.

RESULTS

Fifty-three patients (60% men, median age 65 (23-89) years) undergoing 67 DBE-ERCP procedures (1-3 DBE-ERCP per patient) were enrolled. Reasons for SAA included orthotopic liver transplantation (23%), ulcers (15%), malignancies (43%), difficult cholecystectomy (17%), and other causes (2%). Types of surgery included Roux-en-Y biliodigestive anastomosis (45%), Roux-en-Y gastrectomy (32%), pancreaticoduodenectomy (17%), and Billroth II gastrectomy (6%). The overall DBE-ERCP success rate was 86%. The type of surgery, indications, and the length of time between previous surgery and DBE-ERCP were not statistically associated with DBE-ERCP success. The DBE-ERCP success rate increased from 2018 to 2021.

CONCLUSIONS

DBE-ERCP is a successful procedure in challenging patients with SAA. The improvement in results over time indicates the necessity of adequate training and of centralizing patients in referral centers.

EUS-guided biliary drainage for the management of benign biliary strictures in patients with altered anatomy: A single-center experience

Background and Objectives:

The management of benign biliary stricture in patients with altered anatomy secondary to surgery is challenging. Percutaneous transhepatic biliary drainage (BD) represents the standard therapy for benign biliary stricture, but it is associated with nontrivial morbidity rates. Despite the increasing application of guided BD (EUS-BD) for the management of malignant obstruction, its role in patients with benign biliary stricture is limited. This retrospective study aimed to evaluate the feasibility, safety, and clinical effectiveness of EUS-BD with multiple transanastomotic plastic stent treatment in patients with benign biliary stricture.

Materials and Methods:

This study included consecutive patients who underwent EUS-BD for benign biliary stenosis at our center. EUS-BD with fully covered self-expandable metal stent placement was performed first. When feasible, the stricture was treated by balloon dilation with the placement of a transanastomotic double-pigtail plastic stent. Scheduled procedures were repeated to remove the metal stent and replace the plastic stent to treat the stenosis. Technical success and adverse events (AEs) were assessed.

Results:

Twelve patients underwent EUS-BD for benign biliary strictures. Procedural and clinical successes were achieved in all patients (100%). Multistenting treatment was performed in 10/12 patients (77%). The median number of stents inserted, maximum number of stents placed, and median time of retreatment were 2.4 (range: 1–4), 4, and 3.4 (range: 1–7), respectively. In total, 4/12 patients (33.3%) developed AEs that required endoscopic interventions (Clavien-Dindo Grade III).

Conclusions:

EUS-BD with the placement of multiple trans-stenosis plastic stents is a safe, feasible, and well-tolerated alternative for the management of benign biliary stricture in patients with surgery-altered anatomy. Long-term follow-up is necessary to support our results.
