Abstract
Sickle cell disease (SCD) is an inherited hemoglobinopathy with protean clinical manifestations. The liver could be affected by various SCD-associated complications of an overlapping nature. The clinical presentations of "sickle cell hepatopathy" range from clinically asymptomatic patients to those with life-threatening complications. Herein we report an SCD patient who presented with right upper quadrant abdominal pain and jaundice, eventually diagnosed as a self-limited form of acute sickle cell hepatopathy with overlapping features of acute hepatic crisis and benign intrahepatic cholestasis. Using this patient as an illustration, we will review the spectrum of hepatobiliary presentations in the SCD population.

Abstract
BACKGROUND Pigment gallstones are not uncommon among patients with chronic haemolytic anaemia. But their clinical characteristics have not been described in detail and not been directly compared with the general gallstone population. METHODS Patients at Peking Union Medical College Hospital with haemolytic anaemia and subsequent gallstones from January 2012 to December 2022 were included. Cases were matched (1:2) based on age, sex and location of stones to randomly select non-anaemia patients with gallstones (controls). RESULTS Screening 899 cases of gallstones, we finally included 76 cases and 152 controls. Total cholesterol (TC), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) for cases were 3.02 ± 0.98 mmol/L, 0.89 ± 0.30 mmol/L and 1.58 ± 0.70 mmol/L, respectively, significantly lower than those in the control group (all p < 0.001). TC and HDL were both lower than the normal range, but triglyceride and LDL were within the normal range. Multiple stones were significantly more common for cases (n = 59, 78%) than for controls (n = 44, 29%, p < 0.001). The mean diameter of the maximal gallstone was 1.2 ± 0.6 cm and 1.5 ± 1.0 cm for cases and controls (p = 0.120), respectively. Stones in the elderly (p = 0.002 for univariate analysis, and 0.001 for multivariate analysis) and stones in the bile duct (p = 0.005 for univariate analysis, and 0.009 for multivariate analysis) were found to occur in a shorter period after anaemia. CONCLUSION The lipid profile of haemolytic anaemia with gallstones was distinct, low TC, low HDL, and increased-to-normal LDL, compared with the general gallstone population. Patients with haemolytic anaemia were recommended an abdominal ultrasound if aged older than 50 years, with more frequent follow-up visits.KEY MESSAGESClinical characteristics of gallstones following chronic haemolytic anaemia were described and compared with the general gallstone population.The lipid profiles were distinctly different between the patients with gallstones following chronic haemolytic anaemia and the general gallstone population.Elder patients were complicated with gallstones in a shorter period after anaemia and thus were recommended an abdominal ultrasound if aged older than 50 years, with more frequent follow-up visits.

Abstract
Sickle cell disease is a common genetic disorder affecting >300 000 people across the world. The vast majority of patients cared for in high-resource settings live well into adulthood, but many develop a high burden of disease complications. Good standard of care including disease-modifying agents and transfusion programs limits the number of patients who develop end-stage organ disease, but for those that do, the prognosis can be very poor. Solid organ transplantation is a well-established mode of treatment for patients with sickle cell disease and kidney or liver failure, but appropriate patient selection and perioperative management are important for achieving good outcomes. Hematopoietic stem cell transplantation and gene therapy may offer novel treatment options for adult patients with chronic organ damage in the future, but these are not yet widely available. For now, good, holistic care and early intervention of end-organ complications can minimize the number of patients requiring solid organ transplantation later in life.

Age- and sex-specific rates of gall bladder disease in children with sickle cell disease. Pediatr Blood Cancer 2022; 69:e29863. [PMID: 35997530 DOI: 10.1002/pbc.29863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Revised: 05/28/2022] [Accepted: 06/10/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND Children with sickle cell disease (SCD) have an increased risk for gallstones due to chronic hyperbilirubinemia from hemolysis. Although gallstones are a known complication, there is variability in estimates of disease burden and uncertainty in the association between sex and gall bladder disease (GBD). METHODS This was a retrospective cohort study of children with SCD using administrative claims data (January 1, 2014-December 31, 2018). Population-averaged multivariable panel-data logistic regression models were used to evaluate the association between GBD clinical encounters (outcome) and two exposures (age and sex). Annual GBD risk was calculated using predictive margins, adjusting for disease severity, transfusion frequency, and hydroxyurea exposure. RESULTS A total of 13,745 individuals (of 21,487 possible) met inclusion criteria. The population was evenly split across sex (49.5% female) with predominantly Medicaid insurance (69%). A total of 946 individuals (6.9%) had GBD, 432 (3.1%) had a gallstone complication, and 487 (3.5%) underwent cholecystectomy. The annual risk of GBD rose nonlinearly from 1 to 5% between ages 1 and 19 years with no difference between males and females. Cholecystectomy occurred primarily in individuals with GBD (87%), and neither age nor sex was associated with cholecystectomy in this population. High disease severity (compared with low) more than doubled the annual risk of GBD at all ages. CONCLUSIONS GBD is associated with age but not sex in children with SCD. Neither age nor sex is associated with risk of cholecystectomy. High disease severity increases the rate of GBD at all ages.

Cholecystectomy for asymptomatic gallstones: Markov decision tree analysis. World J Clin Cases 2022; 10:10399-10412. [PMID: 36312509 PMCID: PMC9602237 DOI: 10.12998/wjcc.v10.i29.10399] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2022] [Revised: 05/13/2022] [Accepted: 09/01/2022] [Indexed: 02/05/2023] Open
Abstract
Gallstones are a common public health problem, especially in developed countries. There are an increasing number of patients who are diagnosed with gallstones due to increasing awareness and liberal use of imaging, with 22.6%-80% of gallstone patients being asymptomatic at the time of diagnosis. Despite being asymptomatic, this group of patients are still at life-long risk of developing symptoms and complications such as acute cholangitis and acute biliary pancreatitis. Hence, while early prophylactic cholecystectomy may have some benefits in selected groups of patients, the current standard practice is to recommend cholecystectomy only after symptoms or complications occur. After reviewing the current evidence about the natural course of asymptomatic gallstones, complications of cholecystectomy, quality of life outcomes, and economic outcomes, we recommend that the option of cholecystectomy should be discussed with all asymptomatic gallstone patients. Disclosure of material information is essential for patients to make an informed choice for prophylactic cholecystectomy. It is for the patient to decide on watchful waiting or prophylactic cholecystectomy, and not for the medical community to make a blanket policy of watchful waiting for asymptomatic gallstone patients. For patients with high-risk profiles, it is clinically justifiable to advocate cholecystectomy to minimize the likelihood of morbidity due to complications.

Abstract
Individuals with sickle cell disease (SCD) present both chronic and acute inflammatory events. The TGF-β pathway is known to play a role in immune response, angiogenesis, inflammation, hematopoiesis, vascular inflammation, and cell proliferation. Polymorphisms in the transforming growth factor-beta receptor 3 (TGFBR3) gene have been linked to several inflammatory diseases. This study investigated associations between two TGFBR3 haplotypes and classical laboratory parameters, as well as clinical manifestations, in SCD. We found that individuals with the GG haplotype presented higher levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides, non-HDL cholesterol, total proteins, and globulin than individuals with non-GG haplotypes. In addition, the GG haplotype was associated with a previous history of pneumonia. Individuals with the CGG haplotype presented increased plateletcrit, TC, LDL-C levels, and non-HDL cholesterol. The CCG haplotype was also associated with a previous history of pneumonia. Our findings suggest that individuals with the GG and CGG haplotypes of TGFBR3 present important alterations in lipid profile.

Abstract
Objectives: Previous studies have not addressed microalbuminuria in pediatric patients with sickle cell disease (SCD) in Jeddah, Saudi Arabia. This study aimed to determine the prevalence of microalbuminuria and to identify associated risk factors in children with SCD at King Abdulaziz University Hospital. Results: Overall, 42.5% of the patients enrolled were Saudi Arabian and 51% were male. The mean age was 12.4 years, and the highest percentage (40%) was in the age group of 15-18 years. The prevalence of microalbuminuria was 9.6%, and hematuria was present in 8% of cases. The percentage of patients with hematuria was significantly higher in the microalbuminuria group (22.6%) than in the nonmicroalbuminuria group (6.5%; P = 0.007). The percentage of patients with acute chest syndrome was also higher in the microalbuminuria group (26%) than in the nonmicroalbuminuria group (8%; P = 0.005). The percentage of patients with gallbladder stones was higher in the microalbuminuria group (13%) than in the nonmicroalbuminuria group (2.4%; P = 0.014). However, the mean number of blood transfusions was higher in the nonmicroalbuminuria group than in the microalbuminuria group (P = 0.002). Sickle cell nephropathy manifests as microalbuminuria, begins at an early age, occurs in all types of SCD, and is associated with disease severity.

Abstract
Objective Sickle cell disease is one of the most common inherited hemoglobinopathies in the world. Chronic haemolysis predisposes individuals to the development of bilirubinate cholelithiasis, which can be asymptomatic or can result in cholecystitis, choledocholithiasis, cholangitis, and gallstone pancreatitis. We aimed to determine the prevalence of cholelithiasis and associated gallstone disease among patients with paediatric sickle cell disease in a Saudi hospital. Methods This retrospective study was conducted among all patients aged between 2 and 18 years. We reviewed the medical records of patients diagnosed with sickle cell anaemia. Mean and standard deviation were calculated for quantitative variables, and the Student t-test was used to compare means. The chi-square test was used to assess those risk factors possibly associated with cholelithiasis. A P-value of ≤0.05 was considered statistically significant. Results Approximately 75% of participants developed cholelithiasis (27.5%) at a mean age of 6.9 ± 3.4 years. The frequency of cholelithiasis was significantly higher with increasing age (40.8% in participants 12 years and older) and among those with high levels of haemoglobin S (Hb S) and mean corpuscular volume (MCV). Moreover, cholelithiasis was more frequent among males than females, Saudis than non-Saudis, and in those with sickle cell disease than in those with sickle thalassemia. However, these differences were not statistically significant. Conclusion In this study, the prevalence of cholelithiasis among children with sickle cell anaemia was found to be high. This association was significantly increased with age and high levels of MCV and Hb S.

Abstract
Introduction la drépanocytose est une maladie génétique de transmission autosomique liée à une anomalie de structure de l'hémoglobine qui aboutit à la formation de l'hémoglobine S. Le but de notre étude est de colliger les cas de pathologies digestives rencontrées chez les drépanocytaires de Lubumbashi et d'en ressortir les caractéristiques épidémiologiques et cliniques. Méthodes il s'agit d'une étude rétrospective, descriptive transversale réalisée au Centre de Recherche de la Drépanocytose de Lubumbashi. Elle a concerné les dossiers des patients suivi pour drépanocytose ayant présenté une pathologie digestive au cours de notre période de 3 ans (de janvier 2015 à décembre 2017). Le recueil des données s'est fait grâce à une fiche d'enquête comportant différents paramètres d'étude comprenant: l'âge, le sexe, le motif de consultation, le diagnostic, le type de crise vaso-occlusive, les examens paracliniques réalisés, le traitement à l'hydroxyurée. Résultats nous avons colligé 206 dossiers (N=206) des patients drépanocytaires ayant fait une pathologie digestive sur un total de 403 dossiers examinés, ce qui représente une fréquence de 51,11% des pathologies digestives chez les drépanocytaires. Les 2 sexes sont représentés avec une légère prédominance féminine (51,94%) et un sexe ratio H/F: 0,92. La tranche d'âge la plus représentée est celle comprise entre 1 et 6 ans (32,52%), la moyenne d'âge: 11,8ans; écart-type: 21,9; âges extrêmes: 13 mois et 38 ans. Le motif de consultation est dominé par la fièvre (60,67%), la douleur abdominale (44,66%) et les troubles digestifs (30,09%). Les crises vaso-occlusives abdominales sont retrouvées chez 65 patients (31,55%) parmi lesquels 36 patients ont présenté 1 seule crise, 24 en ont présenté 2 et 5 patients en ont présenté 3. Les pathologies intestinales étaient présentes chez 121 patients (69,41%) dominées par la parasitose intestinale (retrouvée chez 58 patients dont l'examen des selles a mis en évidence 4 parasites: le Yersinia enterocolitis, l'entamoeba histolytica, le Giardia intestinalis et le clostridium difficile); les pathologies gastriques retrouvées chez 105 patients (50,97%) reparties en ulcère gastro-duodénal (45 patients) et gastrite (60 patients); la pathologie vésiculo-biliaire présente chez 40 patients (19,41%) comprenant la lithiase vésiculaire sans cholécystite 32 patients, la cholécystite lithiasique 5 patients et 3 cas de lithiase de la voie biliaire principale; 1 seul cas de pancréatite aigue diagnostiquée. Les pathologies associées les plus retrouvées dans notre étude sont respiratoires avec 169 cas (82,03%), oto-rhino-laryngologiques avec 157 cas (76,21%), les crises vaso-occlusives osseuses (146 cas soit 70,87%), pathologies uro-génitales avec 64 cas (31,06%) et le paludisme chez 51 patients (24,75%). Les atteintes spléniques et hépatiques ont constitué chacun 47 cas (22,81%) et 18 cas (8,73%). L'échographie a était demandé chez 79 patients mais seulement 31 d'entre-eux l'ont réalisé, faute de moyen financier car il coute sur place 20 dollars américains. En cas de splénomégalie cliniquement évidente, le corps de Jolly a été demandé chez 23 patients mais seulement 2 patients l'ont réalisé vu qu'il coute 10 dollars américains. L'hémogramme de routine fait de l'hémoglobine, hématocrite, bilan inflammatoire et la goutte épaisse a été réalisée chez tous nos patients mais le bilan hépatique, les examens des selles, des urines sont préconisés en fonction de la plainte. Sur nos 206 patients, 60 seulement d'entre eux étaient sous traitement à l'hydroxyurée (29,16%). Conclusion les pathologies digestives sont fréquentes chez les drépanocytaires et représentent quasiment la moitié de l'effectif drépanocytaire. Malheureusement, la meilleure prise en charge reste butée à la pauvreté manifeste de la population limitants les examens paracliniques très utiles dans la pathologie digestive rencontrée chez le drépanocytaire.

Abstract
BACKGROUND Sickle Cell Disease (SCD) causes chronic haemolysis which is a risk factor for cholelithiasis. AIM To determine the prevalence and clinical correlates of cholelithiasis in SCD patients in steady state treated at the University of Calabar Teaching Hospital. METHODS This was a prospective study that took place at the Haematology and sickle cell disease clinics, University of Calabar Teaching Hospital, Calabar, Nigeria between January and June 2018. The study population were aged between 1.5-5.5 years and confirmed to have SCD through haemoglobin electrophoresis. A brief history was obtained, and all the patients had a physical examination. Ultrasound examination was performed using a B-mode mind-ray ultrasound machine using a 3.5-5.0 MHz probe after an overnight fast. A Calculus is diagnosed when a highly echogenic structure casting a concrete shadow is detected in the lumen of the gallbladder. RESULTS One hundred and twenty confirmed SCD patients aged between 1.5-55 years were recruited in the study, 69 (57.5%) were males, while 51 (42.5%) were females. The overall prevalence of cholelithiasis was 10%, and it increased with age. The youngest patient with cholelithiasis was 13 years old. All the patients were asymptomatic at the time of examination. At the multivariate level, age, gender, weight and gallbladder volume were associated with gallbladder stones. CONCLUSION The prevalence of cholelithiasis in patients treated at the Sickle Cell Clinic at the University of Calabar Teaching Hospital, Calabar is fairly high. The patients were largely asymptomatic, and cholelithiasis is more common in females than males. This study showed a weak association between blood transfusion and gallbladder stone. It is recommended that routine abdominal ultrasound scan for gallbladder be done for SCD patients from the second decade of life in our environment.

Abstract
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.

Abstract
Sickle cell disease (SCD) is the most prevalent hemoglobinopathy. Survival in patients with SCD has improved over the past few decades. These patients experience a lifetime of repeated acute pain crises, which are thought to result from sickling and microvascular occlusions; acute abdominal pain is common. Moreover, repeated crises often lead to organ dysfunction, such as asplenia, hepatic failure, and renal failure. The spleen, liver, biliary system, kidneys, and gastrointestinal tract can all be affected. Patients may undergo CT to further direct clinical management. We review the spectrum of CT imaging findings of abdominal manifestations in patients with SCD, from the acute microvascular occlusive pain crisis to the potential complications and chronic sequelae.

Abstract
INTRODUCTION Prophylactic laparoscopic cholecystectomy remains controversial and has been discussed for selected subgroups of patients with asymptomatic cholelithiasis who are at high risk of developing complications such as chronic haemolytic conditions. Cholelithiasis is a frequent condition for patients with sickle cell disease (SCD). Complications from cholelithiasis may dramatically increase morbidity for these patients. Our objective was to evaluate the effectiveness of prophylactic cholecystectomy in SCD patients with asymptomatic gallbladder stones. METHODS From January 2000 to June 2014, we performed 103 laparoscopic cholecystectomies on SCD patients. Fifty-two patients had asymptomatic cholelithiasis. The asymptomatic patients were prospectively enrolled in this study, and all underwent a prophylactic cholecystectomy with an intraoperative cholangiography. The symptomatic patients were retrospectively studied. Upon admission, all patients were administered specific perioperative management including intravenous hydration, antibiotic prophylaxis, oxygenation, and intravenous painkillers, as well as the subcutaneous administration of low-molecular-weight heparin. During the same period, 51 patients with SCD underwent a cholecystectomy for symptomatic cholelithiasis. We compared these 2 groups in terms of postoperative mortality, morbidity, and hospital stay. RESULTS There were no postoperative deaths or injuries to the bile ducts in either group. In the asymptomatic group, we observed 6 postoperative complications (11.5%), and in the symptomatic group, there were 13 (25.5%) postoperative complications. DISCUSSION Regarding the SCD complications, we observed 1 case (2%) of acute chest syndrome in an asymptomatic cholelithiasis patient, while there were 3 cases (6%) in the symptomatic group. Vaso-occlusive crisis was observed in 1 patient (2%) with asymptomatic cholelithiasis, and in 4 patients (8%) in the other group. The mean hospital stay averaged 5.8 (4-17) days for prophylactic cholecystectomy and 7.96 (4-18) days for the comparative symptomatic group. CONCLUSIONS Postoperative complications related to SCD were less frequent for asymptomatic patients who had a laparoscopic prophylactic cholecystectomy. This intervention, if performed with perioperative specific management, is safe and helps avoid emergency operations for acute complications including cholecystitis, choledocholithiasis, and cholangitis. For SCD patients, a prophylactic cholecystectomy reduces hospital stays.

Implications of radiologic-pathologic correlation for gallbladder disease in children and young adults with sickle cell disease. Emerg Radiol 2015; 22:543-51.

Abstract
The purpose of this study is to describe gallbladder imaging findings in patients with sickle cell disease, and to determine how they correspond with occurrence of complications, need for cholecystectomy, and surgical pathology. This study is IRB approved and HIPAA compliant. Informed consent requirements were waived. We reviewed records of 77 children with sickle cell disease ages 0-18 years at the time of their first gallbladder imaging study. Demographics, hospital courses, and radiologic and pathologic reports were collected. Two pediatric radiologists independently and retrospectively reviewed the imaging studies. Statistical analysis was performed using kappa statistic, chi-squared test, and ANOVA F-test. Continuous variables were described with mean, median, variance, and range. Patients who underwent cholecystectomy (N = 25) were more likely than the patients who did not undergo cholecystectomy (N = 52) to have gallstones or sludge (100 versus 36.5 %, p = <0.0001) or other gallbladder or biliary abnormality (70.8 versus 1.9 %, p = <0.0001). Patients who did not undergo cholecystectomy more frequently had normal-appearing gallbladders and biliary tracts (63.5 versus 0 %, p = <0.0001). Ninety-two percent of patients with cholecystectomy had chronic cholecystitis on pathology, and 96 % had a complication, including chronic cholecystitis and sequelae of biliary obstruction. Young patients with sickle cell disease, cholelithiasis, and any other biliary imaging abnormality will almost certainly require cholecystectomy, and many will experience complications. The most common surgical pathologic diagnosis in this group is chronic cholecystitis, which has a variable radiologic appearance. Our findings support recommendations to perform elective cholecystectomy for children and young adults with sickle cell disease and cholelithiasis or gallbladder sludge.

Abstract
Liver complications in haemoglobinopathies (thalassaemia and sickle cell disease) are due to several factors, dominated (beside chronic viral infections, not considered here) by chronic iron overload, biliary obstruction and venous thrombosis. Whereas the latter two factors can cause acute hepatic syndromes, all three mechanisms - when becoming chronic- can produce fibrosis and cirrhosis and even, in thalassaemia, hepatocellular carcinoma. These chronic hepatic complications are an indirect consequence of the significant improvement in life expectancy due to the overall amelioration of disease management. The diagnostic approach has benefited from non invasive (biochemical and imaging) approaches which have considerably reduced the indication of liver biopsy. The therapeutic management involves relatively efficient curative medical, endoscopic or surgical methods, but should rest primarily on preventive measures focused on the haematological causative factors but also on hepatic co-morbidities. This chapter will focus on hepatic complications in thalassaemia and sickle cell disease (SCD), without considering the complications related to virus B or C infections which will be described in another chapter.

Abstract
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.

Abstract
SUMMARY BACKGROUND DATA A gallstone is a common disease in sickle cell disease (SCD) patients, and cholecystectomy is the most common surgical procedure performed in patients with SCD. We conducted this study to determine the outcome of laparoscopic cholecystectomy (LC) as the standard surgical treatment for gallstones in adult patients with sickle cell anemia over a long period. PATIENTS AND METHODS Data of all the SCD patients who were operated between April 1994 and December 2008 were collected retrospectively. We analyzed data including age, sex, mode of admission (elective or emergency), indication for LC (chronic or acute cholecystitis), operation time, length of hospital stay, and complications. RESULTS : During 1994 to 2008, there were 6014 patients who underwent LC; of those, 496 (8.25%) patients were SCD patients. The results showed significant differences in the outcome, operative time, hospital stay, and complication rate between 1994 and 2008. CONCLUSIONS LC is a safe procedure in sickle cell patients with a low morbidity rate.

Abstract
BACKGROUND SCA causes chronic haemolysis which is a risk factor for cholelithiasis. OBJECTIVE To determine the prevalence and outcome of children with SCA complicated with gallstones treated at the sickle cell clinic at the children emergency hospital Khartoum state. METHODS 261 patients age 4 months to 16 years were studied. AUS examination was carried out. The 30 patients in whom gall stones were detected followed prospectively from June 1996 to September 2009 when a second AUS examination was obtained. RESULTS Gall stones occurred in 30 patients of whom four were lost to follow up in the first year. The overall prevalence of cholelithiasis was 11.5% and it increased with age. The youngest patient with cholelithiasis was 2 1/2 years old. Haematological variables, bilirubin and sex did not identify a subgroup of patients at higher risk for gallstones. All the patients were asymptomatic at the time of diagnosis. One patient developed symptoms 3years after the diagnosis and he was submitted to surgery. The 25 remaining asymptomatic patients were followed up for 13 years and none of them presented complications related to cholelithiasis during this period. CONCLUSION The prevalence of cholelithiasis in Sudanese children and adolescents with SCA was significant. The large majority patients remained asymptomatic over a long period.

Abstract
We studied 136 males and 105 females with sickle cell anemia to determine the characteristics of the disease in Yemen. Their mean age [± SD (standard deviation)] was 12.8 ± 9.5 years (range: 9 months-40 years). Taiz, Hudaydah and Hajjah governorates, in the South-Central and the Northwestern provinces, showed the highest prevalence. Eighty percent of the patients had family history of the disease, 73.0% patients had history of parental consanguinity and 20.7% of death of relative(s) due to the disease; 5.4% patients were older than 30 years of age. Pain, jaundice and infection were the most frequent features. Splenomegaly, cholelithiasis, osteomyelitis, acute chest syndrome (ACS), osteonecrosis and stroke occurred in 12.0, 9.5, 8.7, 6.6, 6.6 and 2.9%, respectively. Priapism and leg ulcers were rare. The mean laboratory values (obtained in the steady state) were: hemoglobin (Hb) 7.9 g/dL, WBC 14.08 × 10(9)/L, platelet 460 × 10(9)/L, reticulocytes 14.5%, lactate dehydrogenase (LDH) 597 U/L, Hb F (α2γ2) 16.69%, Hb S [β6(A3)Glu→Val, GAG>GTG] 77.31% and Hb A(2) (α2δ2) 1.47%, respectively. There was no significant difference between South-Central and Northwestern provinces regarding clinical events and hematological parameters.

Abstract
Laparoscopic cholecystectomy in patients with sickle cell disease was found to be safe without preoperative blood transfusion. Background: Surgery in patients with sickle cell disease is associated with high morbidity. To reduce this high morbidity, different preoperative transfusion regimens were introduced. However, blood transfusion is associated with problems. This prospective study aims to establish the safety of conducting laparoscopic cholecystectomy without transfusion in sickle cell disease patients. Methods: Forty patients (16 males and 24 females; mean age 26.6 years) undergoing laparoscopic cholecystectomy for cholelithiasis were divided into 2 matched groups: Group I “no transfusion” (n=24 patients; 60%) and Group II “transfusion” (n=16; 40%). In Group II, 9 patients (22.5%) received a simple transfusion and 7 (17.5%) a partial exchange transfusion. Results: Group II patients had significantly higher levels of Hb-S prior to transfusion. They developed a significantly higher complication rate (25% vs. 0%) and subsequently longer hospital stay (3.9±2 vs. 2.1±1.4). Moreover, there was no significant difference in the complications between the simple transfusion and partial exchange transfusion subgroups. Conclusion: Surgery in SCD patients is safe without a preoperative blood transfusion. Moreover, preoperative blood transfusion is associated with significantly higher postoperative complications and longer hospital stay. Hence, a “no transfusion” policy is recommended.

Abstract
The sickle hemoglobin is an abnormal hemoglobin due to point mutation (GAG → GTG) in exon 1 of the β globin gene resulting in the substitution of glutamic acid by valine at position 6 of the β globin polypeptide chain. Although the molecular lesion is a single-point mutation, the sickle gene is pleiotropic in nature causing multiple phenotypic expressions that constitute the various complications of sickle cell disease in general and sickle cell anemia in particular. The disease itself is chronic in nature but many of its complications are acute such as the recurrent acute painful crises (its hallmark), acute chest syndrome, and priapism. These complications vary considerably among patients, in the same patient with time, among countries and with age and sex. To date, there is no well-established consensus among providers on the management of the complications of sickle cell disease due in part to lack of evidence and in part to differences in the experience of providers. It is the aim of this paper to review available current approaches to manage the major complications of sickle cell disease. We hope that this will establish another preliminary forum among providers that may eventually lead the way to better outcomes.

Abstract
BACKGROUND Abdominal pain is a relatively frequent occurrence in sickle cell disease. The aetiology of abdominal pain in sickle cell disease is often difficult to diagnose clinically. Despite the frequent occurrence, diagnostic dilemma, and the need for an accurate, early diagnosis, abdominal pain in sickle cell disease has not been rigorously studied. OBJECTIVE We therefore sought to describe the different presentations and patterns of abdominal pain in persons with sickle cell disease. METHODS A prospective case series of 20 patients was done in which data was collected on demographic characteristics, hemoglobin electrophoresis patterns, a description of the abdominal pain including sites, severity, and type of pain, packed cell volume and the provisional and final diagnosis. RESULTS Haemoglobin S patients were 17 in number constituting eightyfive percent (85%) of our study population whilst the rest 3 were Hb S+C. Most patients (70%) had one site of abdominal pain. The pain was mainly colicky or tightening, moderate to severe in nature and, in some cases, associated with vomiting. We did not find any significant difference between the steady state PCV and the PCV during the acute abdominal pain episodes. The final diagnosis showed that only 38.8% of the patients had vasoocclusive crises and the reliability index between the provisional diagnosis and the final diagnosis was 67%. CONCLUSION Abdominal pain in sickle cell disease may present in different ways and it is important to recognize that the possible diagnoses are numerous. Not all cases are due to vasoocclusive crises. Early diagnosis and prompt treatment can be life saving.

Abstract
This study aims to evaluate the type and prevalence of abdominal sonographic abnormalities in children with sickle cell anemia (SCA). Ninety patients were screened by abdominal sonography. The sonographic abnormal findings were 91% in the liver, 62.2% in the spleen, 14.4% in the gallbladder, and 4.4% in the kidneys. Sonographic imaging revealed hepatomegaly in 79 (87.8%) patients. Three patients (3.3%) had hypoechoic liver lesions. One patient had multiple hypoechoic liver lesions that proved to be an abscess. Gallstones were reported in 10 patients, the youngest of whom was 2.5 years old. The overall prevalence of gallstones was 11.1%, and it increased with age. Two patients (2.2%) had thickened gallbladder wall, and only 1 patient (1.1%) had a sludged gallbladder. Autosplenectomy (asplenia) was detected in 43 (47.8%) patients. Seven (7.8%) patients had hypoechoic lesions. Hyperechoic lesions with spleenomegaly were found in 6 (6.6%) patients. Normal renal echogenecity was reported in 86 (95.6%) patients, 3 (3.3%) patients reported focal hyperechoic lesions, and 1 patient (1.1%) reported an anechoic lesion. In conclusion, abdominal sonographic imaging of patients with SCA revealed a high prevalence of abnormalities in the liver, gallbladder, and spleen but a low prevalence in the kidney.

Abstract
Sickle cell disease (SCD) is an autosomal recessive abnormality of the beta-globin chain of hemoglobin (Hb), resulting in poorly deformable sickled cells that cause microvascular occlusion and hemolytic anemia. The spleen is almost always affected by SCD, with microinfarcts within the first 36 months of life resulting in splenic atrophy. Acute liver disorders causing right-sided abdominal pain include acute vaso-occlusive crisis, liver infarction, and acute hepatic crisis. Chronic liver disease might be due to hemosiderosis and hepatitis and possibly to SCD itself if small, clinically silent microvascular occlusions occur chronically. Black pigment gallstones caused by elevated bilirubin excretion are common. Their small size permits them to travel into the common bile duct but cause only low-grade obstruction, so hyperbilirubinemia rather than bile duct dilatation is typical. Whether cholecystectomy should be done in asymptomatic individuals is controversial. The most common laboratory abnormality is an elevation of unconjugated bilirubin level. Bilirubin and lactate dehydrogenase levels correlate with one another, suggesting that chronic hemolysis and ineffective erythropoiesis, rather than liver disease, are the sources of hyperbilirubinemia. Abdominal pain is very common in SCD and is usually due to sickling, which resolves with supportive care. Computed tomography scans might be ordered for severe or unremitting pain. The liver typically shows sickled erythrocytes and Kupffer cell enlargement acutely and hemosiderosis chronically. The safety of liver biopsies has been questioned, particularly during acute sickling crisis. Treatments include blood transfusions, exchange transfusions, iron-chelating agents, hydroxyurea, and allogeneic stem-cell transplantation.

Abstract
Sickle cell anemia is one of the common hemoglobinopathies around the world. It results from a single change of one amino acid valine instead of glutamic acid in the hemoglobin beta change. This change leads to polymerization of the hemoglobin when the oxygen saturation is lowered, resulting in deformity of the red blood cells and microvascular occlusion. Sickle cell anemia can affect any part of the body and one of the main organs to be affected is the hepatobiliary system either directly from the sicklening process or indirectly as a result of chronic hemolysis and multiple blood transfusions. This manifests in several clinical conditions which poses diagnostic and therapeutic dilemmas to the treating physicians. These hepatobiliary manifestations will be outlined in this review.

Abstract
OBJECTIVES To report the experience of performing laparoscopic cholecystectomy (LC) in patients suffering from sickle cell disease (SCD), and to assess if their postoperative complications can be minimized by shortening the operating time. METHODS Strict measures were taken to minimize the operating times and duration of pneumoperitoneum in SCD patients undergoing LC. Data collected included demographics, preoperative haemoglobin, the surgical technique used, operating times, insufflation pressures, perioperative complications and hospital length of stay. RESULTS In the 5-year period from July 2003 to June 2008, 19 patients with SCD underwent elective LC. Of these, 84% were female. The mean age was 21.5 years. The most common indication for surgery was symptomatic cholelithiasis (60%). The mean preoperative haemoglobin was 8.2g/dL. No preoperative blood transfusions were given. Four patients had preoperative endoscopic retrograde cholangiopancreatography (ERCP). Mean operating time was 27.9 min (range 20-45 min) which is 2.5-6 times quicker than most reports in the literature. There was no conversion to open surgery. Mean hospital length of stay was 2.5 days. Postoperative complications were noted in four patients with painful crises accounting for 50%. There was no mortality. CONCLUSION The study suggests that if stringent measures are taken to shorten the operating time, LC can be safely and effectively performed in SCD patients with minimal perioperative complications.

Abstract
OBJETIVO: Considerando a alta freqüência da colelitíase no paciente pediátrico com doença falciforme e a controvérsia na literatura sobre a abordagem da condição, o presente texto objetiva revisar a literatura disponível. FONTE DE DADOS: Revisão dos estudos sobre colelitíase no paciente falciforme, publicados no período entre 1980 e 2007, em língua inglesa e portuguesa, envolvendo pacientes na faixa etária de zero a 18 anos e utilizando os bancos de dados Medline e Lilacs. SÍNTESE DOS DADOS: A colelitíase é a complicação digestiva mais comum no paciente falciforme e sua incidência aumenta com a faixa etária. Os mecanismos fisiopatológicos são conhecidos, assim como os métodos diagnósticos. A conduta terapêutica consensual na colelitíase sintomática é a colecistectomia, preferencialmente por via laparoscópica. Nos casos assintomáticos, a maioria dos autores recomenda a conduta cirúrgica, para evitar complicações, confusão no diagnóstico diferencial de dor abdominal futura e menor risco cirúrgico. Contudo, não existe consenso na literatura, havendo base para a adoção de conduta expectante. CONCLUSÕES: A doença falciforme tem grandes variações em sua apresentação clinica, história natural e gravidade da hemólise. Algumas populações podem apresentar menor freqüência de colelitíase e menor número de pacientes sintomáticos, possivelmente em razão de variações de haplótipos, fatores ambientais e diferentes manejos clínicos. Ainda não existem dados suficientes na literatura ou estudos randomizados e controlados que possibilitem definir o momento ideal para a colecistectomia no paciente falciforme com litíase assintomática. Dessa maneira, dependendo de características individuais e da população, podem ser aceitos o seguimento clínico ou a indicação precoce de colecistectomia.

Abstract
A 38-year-old Ghanaian man presented with a 6-month history of worsening pruritus, jaundice, and ascites. He was previously fit and well and rarely drank alcohol. Screening tests for chronic liver disease including viral, autoimmune, and other metabolic causes including iron overload were unremarkable. A liver biopsy performed at the referring hospital demonstrated intralobular cholestasis and cirrhosis. He was listed for liver transplantation but subsequently developed sepsis with multiple organ failure and died. The sickle solubility test was positive. Blood smear showed cells consistent with liver failure and no sickle cells. Hemoglobin electrophoresis revealed HbA2 2.8%, HbF 0.5%, and HbS greater than HbA (49.6% vs. 41.3%) in the absence of blood transfusion. Sequence analysis of the beta-globin genes showed he was a compound heterozygote for the Hbs mutation at codon 6 (CAG --> GTG) and a novel mutation at position 844 of intron 2 (betaIVS2-844 C --> A). A diagnosis of sickle hepatopathy causing decompensated cirrhosis was made. This case is unusual insomuch as this patient was asymptomatic for over 35 years and represents a novel presentation of sickle cell disease. Sickle cell disease should be considered in appropriate patients when unusual presentations of liver disease arise.

Abstract
Asymptomatic cholelithiasis is increasingly diagnosed today, mainly as a result of the widespread use of abdominal ultrasonography for the evaluation of patients for unrelated or vague abdominal complaints. About 10-20% of people in most western countries have gallstones, and among them 50-70% are asymptomatic at the time of diagnosis. Asymptomatic gallstone disease has a benign natural course; the progression of asymptomatic to symptomatic disease is relatively low, ranging from 10-25%. The majority of patients rarely develop gallstone-related complications without first having at least one episode of biliary pain ("colic"). In the prelaparoscopy era, (open) cholecystectomy was generally performed for symptomatic disease. The minimally invasive laparoscopic cholecystectomy refueled the discussion about the optimal management of asymptomatic cholelithiasis. Despite some controversy, most authors agree that the vast majority of subjects should be managed by observation alone (expectant management). Selective cholecystectomy is indicated in defined subgroups of subjects, with an increased risk for the development of gallstone-related symptoms and complications. Concomitant cholecystectomy is a reasonable option for good-risk patients with asymptomatic cholelithiasis undergoing abdominal surgery for unrelated conditions. Routine cholecystectomy for all subjects with silent gallstones is a too aggressive management option, not indicated for most subjects with asymptomatic cholelithiasis. An in-depth knowledge of the natural history of gallstone disease is required to select the optimal management option for the individual subject with silent gallstones. Management options should be extensively discussed with the patient; he or she should be actively involved in the process of therapeutic decision making.

Abstract
Sickle cell disease is characterized by chronic hemolytic anemia and vaso-occlusive painful crises. The vascular occlusion in sickle cell disease is a complex process and accounts for the majority of the clinical manifestation of the disease. Abdominal pain is an important component of vaso-occlusive painful crises. It often represents a substantial diagnostic challenge in this population of patients. These episodes are often attributed to micro-vessel occlusion and infarcts of mesentery and abdominal viscera. Abdominal pain due to sickle cell vaso-occlusive crisis is often indistinguishable from an acute intra-abdominal disease process such as acute cholecystitis, acute pancreatitis, hepatic infarction, ischemic colitis and acute appendicitis. In the majority of cases, however, no specific cause is identified and spontaneous resolution occurs. This chapter will focus on etiologies, pathophysiology and management of abdominal pain in patients with sickle cell disease.

Abstract
OBJECTIVE To determine whether elective cholecystectomy is justifiable in children with sickle cell disease (SCD), gallbladder abnormalities, and minimal clinical symptoms. STUDY DESIGN A retrospective review comparing clinical presentations and abdominal ultrasound results with outcomes in 146 children with SCD. RESULTS Ultrasound examination showed sludge or stones in 83 of 146 children (57%). This was found during a diagnostic ultrasound in 59 patients (71%) and during a screening ultrasound in 24 asymptomatic patients (29%). Fifty-four (65%) children with a positive ultrasound underwent cholecystectomy; 13 of these were initially asymptomatic patients who had subsequent development of clinical symptoms. Of the patients with cholecystectomy, 93% had histopathologic evidence of cholecystitis. Perioperative complications were rare, and there were no episodes of postoperative acute chest syndrome. Children who underwent elective surgery had an average 12-days-shorter overall hospital stay than those who underwent emergent surgery (4 vs 16 days, P <.001). CONCLUSIONS Elective laparoscopic cholecystectomy may be safely performed in children with SCD. Surgery should be strongly considered at the time of gallstone diagnosis before symptoms or complications develop. Histopathologic chronic cholecystitis does not correlate with clinical symptoms.

Abstract
Sickle cell anemia is a disease that affects one out of every 600 African Americans. It is often debilitating and can cause many physical restrictions to individuals with the disease. The disease has many complications which can be vexing for patients and their physicians. The hepatic complications attributed to vascular occlusion encompass a variety of clinical syndromes of which the relationship among clinical presentation, biochemical findings, and histologic features remains unclear. The conditions range from the self-limiting hepatic right upper quadrant syndrome (hepatic crisis) to the potentially lethal intrahepatic cholestasis and acute hepatic sequestration syndromes. Few cases have been documented, and there have not been many sizable studies on acute hepatic sequestration in sickle cell disease. This case is useful for clinicians who are not familiar with the intrahepatic vaso-occlusive syndromes in sickle cell disease. It provides insight into the presentation, diagnosis, and management of these syndromes.

Abstract
BACKGROUND The high prevalence and heterogeneity of clinical and haematological phenotypes of sickle-cell anaemia and thalassaemia intermedia (TI) syndromes in the Greek population constitute a major challenge in routine medical practice. PURPOSE To investigate the spectrum and prevalence of abdominal US findings in these patients. MATERIALS AND METHODS The study included 105 patients, 13 homozygous for sickle-cell anaemia (S/S) and 92 with TI syndromes (Th/S, beta(thal)/beta(thal )or beta(thal)/deltabeta(thal)). The patients' ages ranged from 1 to 54 years, with 49 males and 56 females. RESULTS At the time of the examination, 41% of the patients had undergone splenectomy and 23.8% had undergone cholecystectomy. The most frequent US findings (percentages refer to all patients) were: hepatomegaly (70.5%), splenomegaly (48.6%) and cholelithiasis (20%). A bright liver was identified in 3.8% and focal hepatic lesions were present in two patients of the TI group. Functional disorders of the gallbladder concerned mainly patients with sickle-cell syndromes. Of those with S/S, 30.8% had a shrunken spleen. An echogenic pancreas was identified in one patient in each group. Increased renal echogenicity was observed in 17.6% of patients with sickle-cell syndromes. One case of polycystic kidney disease was diagnosed and coexisted with S/S. CONCLUSIONS The value of US imaging in detecting complications of sickle-cell and TI syndromes is still debated. To our knowledge, there are no previous reports concerning the frequency and spectrum of abdominal US findings in patients with these syndromes.

Abstract
BACKGROUND As emergency surgery in sickle cell disease patients is associated with high morbidity, the aim of the study was to assess the safety of laparoscopic cholecystectomy in the acute state for these patients. METHODS Over a 5-year period, April 1994 till December 1998, 35 sickle cell patients with acute cholecystitis had laparoscopic cholecystectomy within the first 5 days of presentation. A retrospective study of these was undertaken. RESULTS Thirty-five patients were diagnosed as having acute cholecystitis with sickle cell disease. There were 26 female and 9 male patients; 5 patients needed preoperative and 1 patient needed postoperative endoscopic retrograde cholangiopancreatography. Twenty-seven patients needed simple transfusion and 8 needed partial exchange; conversion was necessary in two cases (5.7%). The mean hospital stay was 5.3 days and the complication rate was 17.5%. CONCLUSIONS Because of the lack of significant complications, we believe that laparoscopic cholecystectomy for acute cholecystitis is safe and recommended in experienced hands with adequate preoperative preparation for patients with sickle cell disease.

Abstract
BACKGROUND Chronic hemolysis predisposes adults with sickle cell disease (SCD) to the formation of bilirubinate cholelithiasis. METHODS To study the impact of laparoscopic cholecystectomy (LC) on this groups, we reviewed our records of all patients with SCD and cholelithiasis treated electively from 1991 to 1999. During that period, 13 consecutive patients with SCD underwent elective LC for symptomatic cholelithiasis. Nine patients (69.2%) were managed with a preoperative transfusion regimen to achieve a hemoglobin value of >/=10 g/dl, independent of hemoglobin S percentage. Five patients who presented with jaundice were referred for preoperative endoscopic retrograde cholangiopancreatography (ERCP), which identified choledocholithiasis in two of them. Three other patients underwent intraoperative cholangiography, which revealed common bile duct stones in one patient. RESULTS One patient developed pyrexia for 2 days. There were no vaso-occlusive crises or deaths. The mean hospital stay was 3.3 days. CONCLUSIONS LC has proven to be a safe and efficacious method for the treatment of symptomatic cholelithiasis in this high-risk population. Hematologists are now more willing to refer early, well-prepared patients with SCD and uncomplicated gallbladder disease for elective LC.

Abstract
BACKGROUND Cholelithiasis is a well recognized complication of sickle-cell anemia (SCA) because of chronic hemolysis. It is usually asymptomatic but may result in acute cholecystitis or cholangitis. The aim of this study was to assess prevalence of cholelithiasis and its associated factors among Senegalese children and adolescents with SCA. PATIENTS AND METHODS We analyzed the follow-up records and results of systematic clinical, biological and ultrasonographic examinations in 106 patients with SCA aged 11 months to 22 years (median: 10 years, 6 months), followed up in the Albert-Royer Children's Hospital (Dakar). RESULTS Cholelithiasis was detected in 9.4% of the patients. Gender, ethnic group, geographic origin and socioeconomic conditions did not have any association with cholelithiasis frequency. The youngest patient with cholelithiasis was 7 years old, and prevalence of cholelithiasis increased with age. The mean age at the beginning of SCA follow-up was higher among patients with cholelithiasis. They were more frequently transfused and tended to present more frequent pain crises and other complications of SCA. We found no spontaneous clinical manifestations attributed to cholelithiasis. Nevertheless, provoked right upper quadrant pain was more frequently observed in patients with cholelithiasis. Fetal hemoglobin, steady-state hemoglobin, reticulocytes count, serum bilirubin, alkaline phosphatase and transaminase levels were not significantly different in these patients, compared to the others. However, those with cholelithiasis had significantly higher mean red cell volume. CONCLUSION Prevalence of cholelithiasis appears relatively low in Senegalese patients with SCA, probably owing to the tolerance of the Senegal haplotype. Advanced age and severe chronic hemolysis are etiologic factors in evidence. We recommend systematic abdominal ultrasound at least once a year for patients older than 5 years, or when right upper quadrant pain is observed. Cholecystectomy should be performed in cases of cholelithiasis in order to prevent complications.

Abstract
As surgery in sickle cell patients is associated with high morbidity, this study aims to establish the safety of minimally invasive surgery in this high-risk group. Over a four-year period, 71 sickle cell patients underwent laparoscopic cholecystectomy (LC) for cholelithiasis. Five patients had asymptomatic gallstones. Preoperative gastroscopy and endoscopic retrograde cholangiography were performed in 7 and 14 patients, respectively. Forty-two patients were given simple blood transfusions, while 13 received partial exchange transfusions. The mean operative time was 80 minutes and the conversion rate was 5.6%. There were 10 (14%) postoperative complications, the majority of which were respiratory and wound-related. One patient (1.4%) died as a result of postoperative vaso-occlusive crisis. The median hospital stay was 2.5 days. We believe that laparoscopic cholecystectomy is safe in patients with sickle cell hemoglobinopathy who are particularly at risk of developing pigmented gallstones. Therefore, the use of minimally invasive surgery is encouraged in any sickle cell patient undergoing operative intervention.

Abstract
Abdominal ultrasonography was performed on 305 children with sickle cell disease (SCD) (285 SS and 20 S-beta-thalassemia) to establish the prevalence of cholelithiasis in Saudi children with SCD. Their ages ranged from 1 to 18 years (mean 10.45 years). Gallstones were demonstrated in 60 children, giving a prevalence of 19.7%. An additional 50 patients (16.4%) had only biliary sludge. The youngest patient with gallstones was 3 years old. There was a correlation between the presence of gallstones and increasing age. Patients with gallstones were also found to have higher serum bilirubin levels, but their hemoglobin, hematocrit, reticulocyte count, hemoglobin S, and hemoglobin F levels were not significantly different from those of patients without gallstones.

Abstract
BACKGROUND Preoperative transfusions are frequently given to prevent perioperative morbidity in patients with sickle cell anemia. There is no consensus, however, on the best regimen of transfusions for this purpose. METHODS We conducted a multicenter study to compare the rates of perioperative complications among patients randomly assigned to receive either an aggressive transfusion regimen designed to decrease the hemoglobin S level to less than 30 percent (group 1) or a conservative regimen designed to increase the hemoglobin level to 10 g per deciliter (group 2). RESULTS Patients undergoing a total of 604 operations were randomly assigned to group 1 or group 2. The severity of the disease, compliance with the protocol, and the types of operations were similar in the two groups. The preoperative hemoglobin level was 11 g per deciliter in group 1 and 10.6 g per deciliter in group 2. The preoperative value for hemoglobin S was 31 percent in group 1 and 59 percent in group 2. The most frequent operations were cholecystectomies (232), head and neck surgery (156), and orthopedic surgery (72). With the exception of transfusion-related complications, which occurred in 14 percent of the operations in group 1 and in 7 percent of those in group 2, the frequency of serious complications was similar in the two groups (31 percent in group 1 and 35 percent in group 2). The acute chest syndrome developed in 10 percent of both groups and resulted in two deaths in group 1. A history of pulmonary disease and a higher risk associated with surgery were significant predictors of the acute chest syndrome. CONCLUSIONS A conservative transfusion regimen was as effective as an aggressive regimen in preventing perioperative complications in patients with sickle cell anemia, and the conservative approach resulted in only half as many transfusion-associated complications.
