Multicenter evaluation of the clinical utility of laparoscopy-assisted ERCP in patients with Roux-en-Y gastric bypass
Background and Aims
The obesity epidemic has led to increased use of Roux-en-Y gastric bypass (RYGB). These patients have an increased incidence of pancreaticobiliary diseases yet standard ERCP is not possible due to surgically altered gastroduodenal anatomy. Laparoscopic-ERCP (LA-ERCP) has been proposed as an option but supporting data are derived from single center small case-series. Therefore, we conducted a large multicenter study to evaluate the feasibility, safety, and outcomes of LA-ERCP.
Methods
This is retrospective cohort study of adult patients with RYGB who underwent LA-ERCP in 34 centers. Data on demographics, indications, procedure success, and adverse events were collected. Procedure success was defined when all of the following were achieved: reaching the papilla, cannulating the desired duct and providing endoscopic therapy as clinically indicated.
Results
A total of 579 patients (median age 51, 84% women) were included. Indication for LA-ERCP was biliary in 89%, pancreatic in 8%, and both in 3%. Procedure success was achieved in 98%. Median total procedure time was 152 minutes (IQR 109-210) with median ERCP time 40 minutes (IQR 28-56). Median hospital stay was 2 days (IQR 1-3). Adverse events were 18% (laparoscopy-related 10%, ERCP-related 7%, both 1%) with the clear majority (92%) classified as mild/moderate whereas 8% were severe and 1 death occurred.
Conclusion
Our large multicenter study indicates that LA-ERCP in patients with RYGB is feasible with a high procedure success rate comparable with that of standard ERCP in patients with normal anatomy. ERCP-related adverse events rate is comparable with conventional ERCP, but the overall adverse event rate was higher due to the added laparoscopy-related events
Percutaneous transhepatic vs. endoscopic retrograde biliary drainage for suspected malignant hilar obstruction: study protocol for a randomized controlled trial
Abstract
Background
The optimal approach to the drainage of malignant obstruction at the liver hilum remains uncertain. We aim to compare percutaneous transhepatic biliary drainage (PTBD) to endoscopic retrograde cholangiography (ERC) as the first intervention in patients with cholestasis due to suspected malignant hilar obstruction (MHO).
Methods
The INTERCPT trial is a multi-center, comparative effectiveness, randomized, superiority trial of PTBD vs. ERC for decompression of suspected MHO. One hundred and eighty-four eligible patients across medical centers in the United States, who provide informed consent, will be randomly assigned in 1:1 fashion via a web-based electronic randomization system to either ERC or PTBD as the initial drainage and, if indicated, diagnostic procedure. All subsequent clinical interventions, including crossover to the alternative procedure, will be dictated by treating physicians per usual clinical care. Enrolled subjects will be assessed for successful biliary drainage (primary outcome measure), adequate tissue diagnosis, adverse events, the need for additional procedures, hospitalizations, and oncological outcomes over a 6-month follow-up period. Subjects, treating clinicians and outcome assessors will not be blinded.
Discussion
The INTERCPT trial is designed to determine whether PTBD or ERC is the better initial approach when managing a patient with suspected MHO, a common clinical dilemma that has never been investigated in a randomized trial.

Expanding role of self expanding esophageal stents
Esophageal cancer is often diagnosed at a late stage and hence carries a poor prognosis with an overall 5-year survival rate of 10% to 15%. Therefore, palliative treatment primarily aimed at the relieving dysphagia is the only available option. Endoscopic placement of self expanding metal stents (SEMS) has become a widely used method for palliation offering prompt relief of dysphagia and numerous reports have shown it to be safe and effective. Secondary to tissue in-growth into the uncovered segments of the stent, SEMS cannot be removed and hence are not approved for benign indications. With the advent of the removable self expanding plastic stents, the indications for esophageal stent insertion have expanded to as bridge to surgery for patients undergoing neoadjuvant chemotherapy, for refractory benign esophageal strictures, for non-malignant esophageal perforations, leaks and fistulae, and even for variceal hemorrhage. Newer fully covered SEMS that are potentially removable are also being tried for benign indications but await FDA clearance. Similarly biodegradeable stents for benign disorders and radioactive or drug-eluding stents for malignant disease are hoped to improve the management of esophageal diseases. The purpose of this article is to review the expanding role of self expanding stents in the management of esophageal disorders other than palliating malignant dysphagia and fistulae
