Abstract
BACKGROUND Biliary reconstruction technique during liver transplant (LT) for primary sclerosing cholangitis (PSC) remains controversial. This study aimed to evaluate the incidence of biliary complications in patients with PSC having a duct-to-duct (DD) anastomosis or Roux-en-Y hepaticojejunostomy (HJ). METHODS A retrospective medical record review of patients with PSC undergoing LT at a single center between June 1st, 2000 and December 31st, 2022 was performed. Primary and secondary endpoints were the incidence of biliary strictures (anastomotic [BAS] and non-anastomotic strictures [NAS]) and non-stricture complications, respectively. Univariable and multivariable regression analyses were performed to identify associations with BAS formation. Patient survival was assessed using a Kaplan-Meier curve. RESULTS From 105 transplants performed for 101 patients, 54 (51.4%) and 51 (48.5%) received DD and HJ anastomoses. Mean recipient age and follow-up was 47 ± 13 years and 98 ± 69 months. BAS was more common (48.1% vs. 27.5%, OR 2.45, 95% CI 1.09-5.54, p = 0.03) and occurred earlier (4.8 months, IQR 2.3-13.1 vs. 41.8 months, IQR 7.2-88.7, p = 0.001) in the DD than the HJ group. NAS (seen in 36.2% of transplants) had a comparable incidence (p = 0.53) in HJ (38.9%) and DD (33.3%) groups. No difference was seen between cohorts regarding time to NAS, requirement for extended biliary dilatation programs (clinically significant biliary stricture), bile leak, and graft failure. On multivariable analysis, only the anastomotic technique was associated with BAS (DD adjusted OR 3.00, 95% CI 1.19-7.56, p = 0.02). CONCLUSION In carefully selected patients with PSC, DD anastomosis yielded similar outcomes to HJ anastomosis after liver transplantation.

Abstract
Primary sclerosing cholangitis (PSC) is the classical hepatobiliary manifestation of inflammatory bowel disease (IBD) and a lead indication for liver transplantation (LT) in the western world. In this article, we present a Consensus Statement on LT practice, developed by a dedicated Guidelines' Taskforce of the European Society of Organ Transplantation (ESOT). The overarching goal is to provide practical guidance on commonly debated topics, including indications and timing of LT, management of bile duct stenosis in patients on the transplant waiting list, technical aspects of transplantation, immunosuppressive strategies post-transplant, timing and extension of intestinal resection and futility criteria for re-transplantation.

Choledochoduodenostomy continues to be a safe alternative for biliary reconstruction in deceased-donor liver transplantation. Am J Surg 2022; 224:1398-1402. [PMID: 36400602 DOI: 10.1016/j.amjsurg.2022.10.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 09/25/2022] [Accepted: 10/13/2022] [Indexed: 12/14/2022]
Abstract
Debate continues as to whether choledochoduodenostomy (CDD) can be used instead of Roux-en-Y choledochojejunostomy (CDJ) when duct-to-duct (DTD) is not an option. We hypothesized that CDD and CDJ had similar rates of complications. All deceased-donor liver transplantations from September 2011 to March 2020 were categorized by biliary reconstruction. Primary outcomes were bleeding, bile leak, anastomotic stricture, and cholangitis. Of the 1,086 patients, 812 (74.8%) received a DTD; 225 (20.7%) received a CDD; and 49 (4.5%) received a CDJ. Cholangitis was significantly higher in CDJ compared to DTD and CDD (26.5% vs 6% vs 13.8%, p < 0.0001). When controlling for significant confounders, CDJ had 10.2 higher odds of cholangitis (95% CI 4.4-23.2) compared to DTD, and 3.3 higher odds compared to CDD (95% CI 1.4-7.8). When compared to DTD, CDJ and CDD had significantly lower odds of stricture. CDD continues to be a safe alternative for biliary reconstruction in deceased-donor liver transplantation.

Abstract
Sump syndrome – a collection of digested food, debris, stones, bile, and bacteria in a poorly drained, bile duct reservoir – occurs most commonly after a side-to-side choledochoduodenostomy. As choledochoduodenostomies are now less common, sump syndrome is more often characterized as a complication of Roux-en-Y hepaticojejunostomies; however, most cases occur at the hepaticojejunostomy anastomosis. We report a rare case of sump syndrome in the intra-pancreatic remnant common bile duct in a patient with primary sclerosing cholangitis following living donor liver transplant via Roux-en-Y hepaticojejunostomy. Our patient had a history of end-stage liver disease secondary to primary sclerosing cholangitis but presented with recurrent bacteremia and symptoms of acute cholangitis following her transplant. While this complication has not been reported in this population, we know that those with primary sclerosing cholangitis and those undergoing liver transplantation are at very high risk for biliary complications and strictures. Liver transplant is currently our only treatment for primary sclerosing cholangitis, and more than any other group, they are referred for living donor liver transplantation, preferably via Roux-en-Y hepaticojejunostomy. Thus, our patient’s clinical scenario is not uncommon and demonstrates a source of serious infection of which providers must be aware.

Abstract
BACKGROUND Simultaneous splenectomy during liver transplantation (LT) is debated. The present meta-analysis assessed the efficacy and safety of splenectomy on the outcome of LT patients. METHODS We searched PubMed, Embase, and Wanfang databases for relevant studies published until the date of July 15, 2017. Quality assessment of the included studies was performed using a modified Newcastle-Ottawa Scale judgment. The data were analyzed using RevMan5.3 software. RESULTS A total of 16 studies consisting of 2198 patients (892 patients received splenectomy during LT [SPLT group] and 1306 patients received LT only [LT group]) were included in the present meta-analysis. Efficacy analysis revealed that pooled hazard ratio for overall survival (OS) between 2 groups was not significantly different (hazard ratio = 1.03; 95% confidence interval [CI]: 0.71-1.50). SPLT group had less postoperative rejection (odds ratio [OR] = 0.63, 95% CI: 0.50-0.79) and small for size syndrome (OR = 0.23, 95% CI: 0.07-0.79). SPLT group had significantly lower preoperative platelet (mean difference [MD] = -17.23, 95% CI: -19.54, -14.91), but significantly higher postoperative platelet (MD = 170.45, 95% CI: 108.33-232.56). Conversely, SPLT group had significant higher preoperative portal pressure (MD = 1.54, 95% CI: 0.75-2.33) and significant lower postoperative portal pressure (MD = -1.17, 95% CI: -2.24, -0.11). Safety analysis revealed that SPLT group had significantly longer operation time (MD = 56.66, 95% CI: 35.96-77.35), more intraoperative blood loss (MD = 1.08, 95% CI: 0.25-1.91), and more intraoperative red blood cell (RBC) transfusion (MD = 3.77, 95% CI: 3.22-4.33). Furthermore, SPLT group had significantly higher incidence of postoperative hemorrhage (OR = 3.07, 95% CI: 1.92-4.91), postoperative thrombosis (OR = 3.63, 95% CI: 1.06-12.45), and perioperative infection (OR = 2.62, 95% CI: 1.76-3.90). In addition, perioperative mortality was significantly higher in the SPLT group (OR = 3.14, 95% CI: 1.31-7.52). Postoperative hospital stay did not differ significantly between 2 groups (OR = -1.75, 95% CI: -3.66-0.16). CONCLUSIONS Splenectomy benefits LT patients in increasing platelet count. However, splenectomy is a morbid procedure as splenectomy increases operation time, intraoperative blood loss, intraoperative RBC transfusion, and postoperative complications. Splenectomy does not improve OS but increase perioperative mortality. Therefore, splenectomy should be performed only in selective patients.

Clinical outcomes of donation after circulatory death liver transplantation in primary sclerosing cholangitis. J Hepatol 2017; 67:957-965. [PMID: 28690174 DOI: 10.1016/j.jhep.2017.06.027] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2016] [Revised: 06/23/2017] [Accepted: 06/27/2017] [Indexed: 12/12/2022]
Abstract
BACKGROUND & AIM Primary sclerosing cholangitis (PSC) is a progressive fibro-inflammatory cholangiopathy for which liver transplantation is the only life-extending intervention. These patients may benefit from accepting liver donation after circulatory death (DCD), however their subsequent outcome is unknown. The aim of this study was to determine the clinical impact of using DCD liver grafts in patients specifically undergoing transplantation for PSC. METHODS Clinical outcomes were prospectively evaluated in PSC patients undergoing transplantation from 2006 to 2016 stratified by donor type (DCD, n=35 vs. donation after brainstem death [DBD], n=108). RESULTS In liver transplantation for PSC; operating time, days requiring critical care support, total ventilator days, incidence of acute kidney injury, need for renal replacement therapy (RRT) or total days requiring RRT were not significantly different between DCD vs. DBD recipients. Although the incidence of ischaemic-type biliary lesions was greater in the DCD group (incidence rate [IR]: 4.4 vs. 0 cases/100-patient-years; p<0.001) there was no increased risk of post-transplant biliary strictures overall (hazard ratio [HR]: 1.20, 0.58-2.46; p=0.624), or in sub-analysis specific to anastomotic strictures or recurrent PSC, between donor types. Graft loss and mortality rates were not significantly different following transplantation with DCD vs. DBD livers (IR: 3.6 vs. 3.1 cases/100-patient-years, p=0.34; and 3.9 vs. 4.7, p=0.6; respectively). DCD liver transplantation in PSC did not impart a heightened risk of graft loss (HR: 1.69, 0.58-4.95, p=0.341) or patient mortality (0.75, 0.25-2.21, p=0.598). CONCLUSION Transplantation with DCD (vs. DBD) livers in PSC patients does not impact graft loss or patient survival. In an era of organ shortage, DCD grafts represent a viable therapeutic option for liver transplantation in PSC patients. Lay summary: This study examines the impact of liver transplantation in primary sclerosing cholangitis (PSC) with organs donated after circulatory death (DCD), compared to donation after brainstem death (DBD). We show that in appropriately selected patients, the outcomes for DCD transplantation mirror those using DBD livers, with no significant differences in complication rate, patient survival or transplanted liver survival. In an era of organ shortage and increasing wait-list times, DCD livers represent a potential treatment option for transplantation in PSC.
