Liver transplantation for acute liver failure accompanied by severe acute pancreatitis

Two rare pancreatic parenchymal hemorrhagic lesions associated with acute pancreatitis in acute liver failure: a case report and literature review

Acute pancreatitis is an uncommon occurrence in acute liver failure. Furthermore, such cases are rarely complicated by parenchymal hemorrhages. Herein, we report the case of a 69-year-old male patient with multiple pancreatic parenchymal hemorrhages concomitant with acute liver failure. The patient underwent conservative treatment for acute liver failure caused by hepatitis B virus infection. Plain computed tomography on the 30th day revealed two high-density mass lesions in the pancreatic body and tail, which were suspected to be multiple pancreatic parenchymal hemorrhages. Despite restarting gabexate mesylate, the patient died of multiple organ failure on the 49th day. The clinical information of the present case and our literature review of 61 similar cases in 43 case reports identified via a systematic keyword search of the PubMed database, which described acute pancreatitis concomitant with acute hepatitis and acute liver failure, will aid physicians in the diagnosis and treatment of this rare condition.

High risk of complications and acute-on-chronic liver failure in cirrhosis patients with acute pancreatitis

BACKGROUND & AIMS

Acute pancreatitis (AP) is a frequent indication for hospitalization and may present with varying degrees of severity. AP often coincides with hepatic disease, yet the impact of liver cirrhosis (LC) on the course of AP is uncertain, and early identification of patients at risk for complications remains challenging. We aimed to assess the impact of LC on the development of pancreatic and extra-pancreatic complications of AP, and to identify predictors of adverse outcomes in cirrhotic patients.

METHODS

All adult patients with LC and AP (LC-AP, n = 52) admitted to our institution between 01/2011-03/2020 were subjected to a 1:2 matched-pair analysis with patients with AP but without LC (NLC-AP, n = 104).

RESULTS

At hospital admission, Glasgow-Imrie and Ranson scores as well as markers of systemic inflammation were comparable in LC-AP and NLC-AP patients, and both groups had similar rates of necrotizing AP. Infectious complications were more prevalent, and medical interventions were performed more often and with higher complication rates in LC-AP patients. While only 12.5% of NLC-AP patients developed organ failures, 48% of LC-AP patients developed single (7.7%) or multiple organ failure (40.4%), resulting in 44% of LC-AP patients with acute-on-chronic liver failure (ACLF). Patients with overt portal hypertension were particularly prone for decompensation. Mortality was higher among LC-AP compared to NLC-AP patients (6-month mortality 25% vs. 1.9%, p < 0.001), and SOFA and MELD scores at admission most accurately predicted outcomes in LC-AP.

CONCLUSION

Among AP patients, concomitant cirrhosis substantially increases the risk for infections, periprocedural complications, multiorgan failure and death.

Poor prognosis of liver transplantation for acute liver failure with acute pancreatitis: Two case reports

INDUCTION

Liver transplantation (LT) is the only final therapy for patients with acute liver failure (ALF) that cannot be controlled by conservative treatment. Acute pancreatitis (AP) is a recognized complication of ALF. The pathogenesis of AP in ALF patients has not yet been elucidated. The appearance of AP complicates the patients condition and causes a significantly increased risk of mortality.

PATIENT CONCERNS

We report 2 fatal cases who were both admitted with yellowing of skin and sclera with general weakness lasting for 2 weeks.

DIAGNOSIS

After admission, the laboratory examination of case 1 showed liver dysfunction with serum levels of total bilirubin (TB) 270 μmol/l, alanine aminotransferase (ALT) 106 U/l. Abdominal computed tomography (CT) showed pelvic and peritoneal cavity fluids, occupation of left lateral lobe of liver and unclear margin of pancreas. The clinical laboratory findings of case 2 revealed TB 351.1 μmol/l, ALT 252 U/l, blood lactic acid 18 mmol/l, ammonia 209 μmol/l. And abdominal CT showed pancreatic exudation. They were both diagnosed with acute liver failure, hepatic encephalopathy and AP which was confirmed during the operation.

INTERVENTIONS

They were both received a routine orthotopic LT.

OUTCOMES

After the surgery, their liver functions recovered well, and they received conventional conservative treatment for pancreatitis. However, the treatment was not adequately effective, and the infection was too serious and both died of multiple organ failure despite emergency rescue efforts on day 21 and day 19 after LT.

CONCLUSION

AP is a serious complication that can contribute to prohibitive morbidity and mortality in LT patients. For this reason, the vulnerable state of the pancreas and the scoring system must be defined to help clinicians decide whether a patient is suitable for liver transplantation, and the clinical experience in the treatment of pancreatitis after LT needs to be summarized as an optimal treatment guideline to facilitate better treatment.
