Laparoscopic cholecystectomy in children with sickle cell anemia and the role of ERCP

Jaundice in a Child with Sickle Cell Anemia: A Case Based Approach

Sickle cell anemia (SCA) is an autosomal recessive disorder caused by a mutation in beta globin gene. Hepatobiliary system is affected in 10-40% of patients with SCA and has a multifactorial etiology. The authors present a child with SCA and conjugated hyperbilirubinemia due to biliary obstruction. He underwent endoscopic retrograde cholangiopancreatography (ERCP) and biliary stenting, had complications of post sphincterotomy bleed, retroperitoneal hematoma and post laparoscopic cholecystectomy sepsis with acute sickle hepatic crisis. He was managed successfully and is doing well on follow-up. Here authors discuss a stepwise approach in management of jaundice in a patient with SCA. Patients with SCA are prone to develop vaso-occlusive crisis (VOC) during periods of stress. VOC affects the liver as acute sickle hepatic crisis, acute hepatic sequestration or sickle cell intrahepatic cholestasis and is collectively termed as sickle cell hepatopathy. Hemolysis due to sickling results in cholelithiasis with its associated complications. These patients are vulnerable to viral hepatitis and hemochromatosis due to multiple blood transfusions. There may be a concomitant acute viral hepatitis, drug induced liver injury, Budd-Chiari syndrome or other chronic liver diseases. These conditions have considerable clinical overlap and may coexist, making the evaluation more challenging. Detailed history, examination and investigations are required for differentiation of etiology. Periods of stress must be tackled with proper hydration, oxygen supplementation, maintaining hemoglobin >10 g/dL, and a low hemoglobin S fraction. Patients with SCA and conjugated hyperbilirubinemia are "high-risk" and best managed by a multidisciplinary team. Preventive strategies like timely vaccinations, chelation, etc. must be practised.

Clinical management of sickle cell liver disease in children and young adults

Liver involvement in sickle cell disease (SCD) is often referred to as sickle cell hepatopathy (SCH) and is a complication of SCD which may be associated with significant mortality. This review is based on a round-table workshop between paediatric and adult hepatologists and haematologists and review of the literature. The discussion was prompted by the lack of substantial data and guidance in managing these sometimes very challenging cases. This review provides a structured approach for the diagnosis and management of SCH in children and young adults. The term SCH describes any hepatobiliary dysfunction in the context of SCD. Diagnosis and management of biliary complications, acute hepatic crisis, acute hepatic sequestration and other manifestations of SCH are discussed, as well as the role of liver transplantation and haemopoietic stem cell transplantation in the management of SCH.

Complications in pediatric laparoscopic cholecystectomy: systematic review

Laparoscopic cholecystectomy (LC) is the gold standard for surgical management in symptomatic children, but it is not without complications, bile duct injury being among the most feared. This study reviewed the complications of LC in children. MEDLINE/PubMed, CENTRAL and Lilacs were reviewed for LC. Studies in patients ≤ 18 years of age published in English, Portuguese or Spanish were selected by two independent reviewers. Data were collected for patients' characteristics, surgical information, complications, mortality and follow-up. Twenty-four papers were identified and offered 2783 patients. Mean age was 11 years (3 months-18 years). In the 93/2783 (3.3%) complications, single-port procedures were associated with seven (7.5%), 3/4-port with 81 (87.1%) and the number of ports were not specified in five. Routine cholangiography was not part of the protocol in any of the reports. Complications included wound issues (n = 24), perforation (n = 14), bleeds (n = 13), biliary tree complications (n = 9), sickle cell crisis (n = 8), fever (n = 6), leaks (n = 4), pain (n = 3), nausea/emesis (n = 3) and others (n = 9). Two of these patients had a history of obesity and cholecystitis and only two biliary tree lesions were diagnosed intra-operatively. Seventeen cases (18.3%) required re-intervention: 15 surgical and two endoscopic. Issues related to biliary tree included: common bile duct lesion (n = 6), biliary fistula (n = 3), clip dislocation from cystic duct (n = 1), cholangitis (n = 1) and calculus (n = 1). There was no mortality, and the mean follow-up period was 10.3 months (1 month-5 years). LC is safe in children and, although most complications are minor, almost 1/5 complications require interventions, mostly due to bleeding and biliary tree complications. Mortality has not been reported in pediatric LC.

What surgical approach would provide better outcomes in children and adolescents undergoing cholecystectomy? Results of a systematic review and meta-analysis

Background

There is a lack of evidence on the surgical approach for children and adolescents undergoing cholecystectomy. Therefore, the aim of this systematic review is to compare the safety and efficacy of minimally invasive cholecystectomy to open cholecystectomy in children and/or adolescents.

Main body

A search was conducted on MEDLINE, PubMed, Cochrane and Embase from inception to October 2018. We included comparative studies investigating outcomes following robotic-assisted, laparoscopic and/or open cholecystectomy in children and/or adolescents. The outcomes of interest included post-operative complication rate, operation time, length of hospital stay, post-operative pain and conversion to open procedure. The Newcastle-Ottawa Scale was used to assess the risk of bias. Meta-analysis was performed using random-effect models.

Twenty-one studies were included involving 927 children and/or adolescents. All, but one, compared outcomes between laparoscopic versus open cholecystectomy. The great majority of the included studies presented a low risk of bias. Patients undergoing laparoscopic cholecystectomy had less post-operative complications (RR: 0.57; 95%CI 0.35 to 0.94), reduced length of hospital stay (MD − 3.73; 95%CI − 4.88 to − 2.59), but longer operative time (MD 26.61; 95%CI 9.35 to 43.86) when compared to open cholecystectomy. The average conversion from laparoscopic to open cholecystectomy was 7% across studies.

Conclusions

The current evidence suggested that laparoscopic cholecystectomy in children and/or adolescents is safe resulting in lower rates of postoperative complications and length of stay, but longer operative times, when compared to the open approach.

Perioperative care of children with sickle cell disease: A systematic review and clinical recommendations

Children with sickle cell disease (SCD) require specific perioperative care, and clinical practice in this area remains poorly defined. We aimed to conduct a systematic, PRISMA-based review of the literature, available clinical guidelines and practice recommendations. We also aimed to extract any valuable information for the "best of available-evidence"-based prevention of perioperative adverse events in children with SCD, and highlight the most urgent priorities in clinical research. As data sources, US National Library of Medicine, Medline, National Guideline Clearinghouse, International Guideline Network, TRIP databases were searched for any content until January 2019. We also included institutional, consortia and expert group guidelines. Included were reports/guidelines in English, French, German, and Italian. Excluded were reports on obstetrical and fetal management. We identified 202 reports/guidelines fulfilling the criteria outlined above. A majority focused on visceral, cardiovascular and orthopedic surgery procedures, and only five were multicenter randomized controlled trials and two prospective randomized studies. After grading of the quality of the evidence, the extracted data was summarized into clinical recommendations for daily practice. Additionally, we designed a risk-grading algorithm to identify contexts likely to be associated with adverse outcomes. In conclusion, we provide a systematic PRISMA-based review of the existing literature and ancillary practice and delineate a set of clinical recommendations and priorities for research.

The Liver in Sickle Cell Disease

Patients with sickle cell disease can develop liver disease as a result of intrahepatic sickling of erythrocytes, viral hepatitis and iron overload secondary to multiple blood transfusions, and gallstone disease as a result of chronic hemolysis. The spectrum of clinical liver disease is wide and often multifactorial. Some patients develop cirrhosis that may progress to end-stage liver failure. Limited evidence exists for medical treatments. Exchange blood transfusions may improve outcomes in the acute liver syndromes. Liver transplantation may be an option for chronic liver disease. The role for prophylactic cholecystectomy in preventing complications of gallstone disease is controversial.

Laparoscopic cholecystectomy for cholelithiasis in children with sickle cell disease

Patients with sickle cell disease (SCD) suffer from an increased incidence of gallstone formation due to hemolysis of sickled red blood cells; this leads to an increased level of bilirubin in secreted bile that becomes a nidus for pigment stone formation. Laparoscopic cholecystectomy (LC) is considered a standard operative procedure for gallstone disease mainly due to lower postoperative wound complaints, faster recovery, better postoperative cosmetic results, shorter hospital stay, and earlier return to work. Although numerous studies have been published addressing both the advantages and complications of LC in acute calcular cholecystitis, there is still limited evidence concerning the safety and efficacy of LC for the management of cholelithiasis in pediatric patients with SCD, and controversies remain unresolved. In this review, we aim to comprehensively study the available literature and propose evidence-based practice recommendations for the optimal management of gallstones in pediatric SCD patients. The current practice differs greatly depending on the prevalence of SCD in a particular geographic area. We acknowledge the limited number of patients reported, the lack of randomized control trials addressing the practice of specific recommendations, and the need for further evidence-based studies.

Elective cholecystectomy reduces morbidity of cholelithiasis in pediatric sickle cell disease

BACKGROUND

Cholelithiasis is a frequent complication in pediatric sickle cell disease (SCD). Though it is standard practice to perform a cholecystectomy in pediatric SCD patients with symptoms of cholelithiasis, the use of elective cholecystectomy for asymptomatic patients remains controversial.

PROCEDURE

Records of 191 pediatric sickle cell patients with cholelithiasis who underwent cholecystectomy were retrospectively reviewed. Patients classified as follows: (i) elective-no preoperative symptoms, cholelithiasis on screening ultrasound, comprehensive preoperative plan; (ii) symptomatic-preoperative symptoms of cholelithiasis on diagnostic ultrasound, comprehensive preoperative plan; or (iii) emergent-hospitalization for acute cholecystitis symptoms, cholelithiasis on diagnostic ultrasound, limited preoperative preparation. We compared the morbidity of cholecystectomy by examining pre- and post-cholecystectomy hospital admission days, length of stay for cholecystectomy, and surgical complications.

RESULTS

Patients with SCD underwent a total of 191 cholecystectomies over a 10-year period: 51 elective, 110 symptomatic, and 30 emergent. Patients who required emergent cholecystectomy had a longer postoperative hospitalization time than elective or symptomatic cholecystectomy (7.3 vs 4.3, P < 0.001). Baseline values for total bilirubin and aspartate aminotransferase (AST) were significantly elevated (P < 0.02 and P < 0.07, respectively) in patients requiring emergent cholecystectomy.

CONCLUSIONS

This represents the largest reported retrospective review of pediatric cholelithiasis and cholecystectomy in SCD to date. These data strongly suggest that elective cholecystectomy decreases morbidity associated with emergent cholecystectomy. The overall outcomes for symptomatic and elective patients are favorable. However, our study indicates the need for prospective studies to identify clinical indicators for those emergent patients.

Changing pattern of indications of endoscopic retrograde cholangiopancreatography in children and adolescents: a twelve-year experience

BACKGROUND

There are few data regarding endoscopic retrograde cholangiopancreatography (ERCP) usefulness in children and adolescents. We reviewed the long-term experience with diagnostic and therapeutic ERCP in a tertiary single center in Southern Brazil.

METHODS

A retrospective chart review of patients aged 0-18 years who had undergone ERCPs from January 2000 to June 2012 was done. Data on demographics, indications, diagnosis, treatments, and complications were collected.

RESULTS

Seventy-five ERCPs were performed in 60 patients. The median age of the patients at the procedure was 13.9 years (range: 1.2-17.9). Of the 60 patients, 47 (78.3%) were girls. Of all ERCPs, 48 (64.0%) were performed in patients above 10 years and 35 (72.9%) of them were in girls. ERCP was indicated for patients with bile duct obstruction (49.3%), sclerosing cholangitis (18.7%), post-surgery complication (12%), biliary stent (10.7%), choledochal cyst (5.3%), and pancreatitis (4%). The complication rate of ERCP was 9.7% involving mild bleeding, pancreatitis and cholangitis. Patients who had therapeutic procedures were older (13.7±3.9 vs. 9.9±4.9 years; P=0.001) and had more extrahepatic biliary abnormalities (82% vs. 50%; P=0.015) than those who had diagnostic ERCPs. A marked change in the indications of ERCPs was found, i.e., from 2001 to 2004, indications were more diagnostic and from 2005 therapeutic procedures were predominant.

CONCLUSIONS

Diagnostic ERCPs are being replaced by magnetic resonance cholangiopancreatography and also by endoscopic ultrasound. All these procedures are complementary and ERCP still has a role for therapeutic purposes.

Acute liver function decompensation in a patient with sickle cell disease managed with exchange transfusion and endoscopic retrograde cholangiography

Sickle cell intrahepatic cholestasis is a relatively uncommon complication of homozygous sickle cell anemia, which may lead to acute hepatic failure and death. Treatment is mainly supportive, but exchange transfusion is used as salvage therapy in life threatening situations. We describe a case of a 16-year-old female with homozygous sickle cell anemia who presented to the emergency room with fatigue, malaise, dark urine, lower back pain, scleral icterus and jaundice. She was found to have marked hyperbilirubinemia, which persisted after exchange transfusion. Because of the concomitant presence of gallstones and choledocholithiasis, the patient underwent endoscopic ultrasound and laparoscopic cholecystectomy followed by endoscopic retrograde cholangiography and sphincterotomy.
