EUS-guided enterocolostomy with lumen-apposing metal stent for palliation of malignant small-bowel obstruction (with video).

BACKGROUND AND AIMS: Interventions for malignant small-bowel obstruction (SBO) may be limited by extent of peritoneal disease, rendering surgical or traditional endoscopic methods (ie, luminal stenting or decompressive gastrostomy) unfeasible. We demonstrated the novel use of EUS-guided lumen-apposing metal stent placement for enterocolonic bypass in patients with malignant SBO who were deemed high risk for surgery. METHODS: Across 3 tertiary U.S. centers, a retrospective series of consecutive patients underwent attempted EUS-guided enterocolostomy (EUS-EC) for palliation of acute SBO because of malignant causes. Technique and devices used were described, and patient demographics and outcome data were collected. RESULTS: Ten patients were included, of whom 9 (90.0%) were men, with a mean age of 64.5 ± 14.0 years and who were 1.5 ± 2.1 years postdiagnosis. Technical success was achieved in 8 of 10 patients (80.0%) and clinical success in 7 of 10 (70.0%), with a single major adverse event (10.0%) of aspiration. Median time until resumption of oral intake was 1.0 day (range, 0-8) after the procedure, with an interval to discharge home of 6.5 days and survival of 57.0 days. CONCLUSIONS: EUS-EC is a new alternative for palliation of acute SBO because of advanced malignant disease when conservative measures fail and other surgical or endoscopic options are not possible. Additional larger studies with longer duration of follow-up are needed to further define efficacy and safety of this approach.

Choledochoduodenostomy is associated with fewer post-transplant biliary complications compared to Roux-en-Y in primary sclerosing cholangitis patients.

BACKGROUND: For primary sclerosing cholangitis (PSC) patients undergoing liver transplantation (LT), a consensus regarding biliary reconstruction remains unresolved. Choledochoduodenostomy (CDD) represents an alternative to Roux-en-Y (RY) and duct-to-duct. We compared long-term post-transplant outcomes between CDD and RY. METHODS: This was a retrospective review of patients transplanted for PSC who received CDD or RY, with minimum 12-months follow-up. The primary outcome was need for biliary intervention, with either percutaneous transhepatic cholangiography (PTC) or endoscopic retrograde cholangiopancreatography (ERCP). Secondary outcomes included biliary stricture(s) and cholangitis admission(s). RESULTS: Ninety-three patients were transplanted between August 2004 and October 2019 (34 living donor [LDLT] and 59 deceased donor [DDLT]; 40 RY, 53 CDD). Need for either ERCP or PTC was similar (45.0% RY vs. 32.1% CDD, P = .203), though RY exhibited more anastomotic strictures (AS) (35.0% RY vs. 11.3% CDD, P = .006), which was also observed in LDLT subanalyses (50.0% LDLT/RY vs. 10.0% LDLT/CDD; P = .036). Cholangitis admissions were more frequent in RY versus CDD (37.5% vs. 15.1%, P = .013). CONCLUSIONS: CDD does not impart greater risk of biliary complications, and RY may have an incremental effect combined with LDLT status for predisposing to AS. CDD maintains standard endoscopic access without additional risk of biliary complications, thus should be considered when anatomically feasible.
