The role of ERCP in patients with pancreatico-biliary problems in the setting of hematopoietic stem cell transplant

Complex profile of multiple hepatobiliary and gastrointestinal complications after hematopoietic stem cell transplantation in a child with Nijmegen breakage syndrome

Patients with Nijmegen breakage syndrome (NBS) can develop life-threatening immunodeficiency, which should be treated with hematopoietic stem cell transplantation (HSCT). We report the case of a 14-year-old girl with NBS who due to an increasing number of severe complications was referred for HSCT from a matched unrelated donor. After reduced-intensity conditioning and transplantation of peripheral blood hematopoietic cells, during the early post-transplant period (days 0-30), the girl suffered from severe mucositis, fever episodes, mild acute renal injury and facial vasculitis. All these complications were managed successfully. During the intermediate post-transplant period (days 30-100) a number of hepatic and gastrointestinal complications occurred, including cholecystitis, cholelithiasis with choledocholithiasis, pancreatitis as well as acute bleeding from the lower gastrointestinal tract caused by rectal and recto-sigmoid junction ulcers. All the obstacles were obviously attributable both to the primary congenital disease, its complications, and transplantation itself. We overcame these complications and treated the patient with the best possible and safe methods. The multidisciplinary approach based on combined surgical, endoscopic and conservative management of multiple post-transplant complications was successful for the patient.

Role of ERCP in patients after hematopoietic stem cell transplantation

BACKGROUND

The role of ERCP in evaluating patients with hepatobiliary dysfunction after hematopoietic stem cell transplantation (HSCT) has not been well-defined.

OBJECTIVE

The aim of this study was to better define the role of ERCP after HSCT by reviewing our institutional experience, including indications, findings, and outcomes.

DESIGN

Retrospective review of ERCP findings and outcomes in patients after HSCT.

SETTING

MD Anderson Cancer Center from 1997 to 2009.

PATIENTS

A total of 40 patients had ERCP after HSCT during the study period.

INTERVENTION

ERCP.

MAIN OUTCOME MEASUREMENTS

Overall survival.

RESULTS

A total of 40 patients had ERCP after HSCT during the study period. Seventeen patients had biliary strictures (group 1), and 13 proved to be malignant. Ten patients had common duct stones (group 2). Thirteen patients (group 3) had neither stones nor stricture. Findings in group 3 included bile duct leak (1), dilation without stricture (2), resolution of pretransplant strictures (3), biliary sludge (1), or normal ducts (6). The normal subset proved to have hepatic graft-versus-host disease (GVHD) (3), hepatic drug toxicity (1), hepatic recurrence of myeloma (1), or pancreatitis with biliary sludge (1). Patients with GI GVHD were equally distributed among the 3 groups. Group 1 had 100% mortality with median time to death being 85 days after ERCP. Group 2 had 30% mortality with median time to death of 584 days after ERCP. Ten of 13 patients in Group 3 died at a median of 148 days after ERCP. The only procedural complication was a mild case of pancreatitis.

LIMITATIONS

Retrospective study at a single center.

CONCLUSION

One in every 130 post-HSCT patients required ERCP evaluation. Biliary stricture is frequently caused by recurrent or new malignancy, particularly after autologous HSCT. GI GVHD is not associated with biliary stricture. ERCP procedural risks in HSCT patients are acceptable.

Hepatobiliary complications of hematopoietic cell transplantation, 40 years on

Liver problems caused by infection, cholestasis and sinusoidal liver injury in the months following HCT have become less frequent because of preventive and pre-emptive strategies. When patients develop jaundice after transplant, the time to search for treatable causes is early in the course of jaundice, as the risk of mortality rises steeply with small increments of serum bilirubin above normal. Chronic hepatitis C, persistent GVHD, cirrhosis and hepatocellular carcinoma are significant liver problems in the longest-lived survivors of HCT.
