Abstract
PURPOSE Children undergoing splenectomy for hemolytic anemia often have cholelithiasis, which may or may not be symptomatic. It is unclear whether concurrent cholecystectomy increases length of stay or morbidity after splenectomy. The purpose of this study was to compare morbidity among children undergoing laparoscopic splenectomy alone versus splenectomy with concurrent cholecystectomy in patients with hemolytic anemia. METHODS We retrospectively evaluated children with hemolytic anemia undergoing non-traumatic laparoscopic splenectomy in the National Surgical Quality Improvement Program-Pediatric database (2012-2020). Outcomes were compared for patients undergoing splenectomy alone (n = 1010) versus splenectomy with cholecystectomy (n = 371). Pearson's Chi-square and Student's t-tests were utilized as appropriate. Propensity score-matching was completed, controlling for eight demographic and clinical variables. RESULTS 1381 patients were identified, 73.1% undergoing splenectomy alone and 26.9% splenectomy with cholecystectomy. Splenectomy with cholecystectomy patients were older (10.9 years vs. 8.4 years, p < 0.01), more likely to have hereditary spherocytosis (56.1% vs. 40.8%, p < 0.01), less likely to have sickle cell disease (12.1% vs. 33.5%, p < 0.01), more likely ASA class 1 or 2 (49.3% vs. 42.1%, p < 0.01), and had similar preoperative hematocrit levels (29.6 vs. 29.3, p = 0.33). The splenectomy with cholecystectomy group was less likely to receive preoperative blood transfusions (13.5% vs. 25.4%, p < 0.01). There were 360 pairs selected on propensity score-matching, and splenectomy with cholecystectomy was associated with increased operative time (182 min vs. 145 min, p < 0.01) and decreased occurrences of a postoperative transfusion (4.2% vs. 8.9%, p = 0.01). Length of stay after surgery (2.5 days vs. 2.3 days, p = 0.13), composite morbidity (3.9% vs. 3.4%, p = 0.69), and 30-day readmission rates (3.3% vs. 7.4%, p = 0.08) were all similar. CONCLUSIONS Splenectomy with cholecystectomy is associated with similar postoperative morbidity, length of stay and readmission rates compared to splenectomy alone. These data support the safety of concurrent cholecystectomy with splenectomy for children with cholelithiasis in the setting of hemolytic anemia. TYPE OF STUDY Retrospective Cohort Study. LEVEL OF EVIDENCE Level III.

Abstract
INTRODUCTION Subtotal or total splenectomy are recommended in severe and should be considered in intermediate forms of hereditary spherocytosis (HS). Data on laparoscopic subtotal splenectomy (LSTS) in HS patients are sparse. METHODS Thirty three patients with HS (median age 10.7 years (yrs), range 1.8-15.5) underwent LSTS. Baseline and follow-up investigation included haematological parameters, microscopic analysis of pitted erythrocytes (pitE), and B-cell subpopulations assessed by flow cytometry. Results were compared to those of non-splenectomised HS patients, HS patients after total splenectomy (TS), and healthy individuals. RESULTS After LSTS, haemoglobin levels were normalised in all patients. During median long-term follow-up of 3.9 yrs (range 1.1-14.9), only four patients presented mild anaemia. Despite re-growing of the remnant spleen none of the patients required a second surgical intervention. As compared to TS, PitE in LSTS patients were significantly lower and indicated normal to only moderately decreased spleen function. Relative but not absolute IgM memory B-cell counts were reduced in both LSTS and TS patients. CONCLUSIONS LSTS is effective for the treatment of patients with HS. A small remnant spleen is sufficient to provide adequate phagocytic function and to induce a pool of IgM memory B-cells.

Abstract
BACKGROUND Gallstones are common in hereditary spherocytosis (HS) and other chronic hemolytic diseases, with most affected patients being asymptomatic. Whether and how asymptomatic gallstones should be treated is controversial. METHODS We conducted a retrospective cohort study of pediatric patients with HS and asymptomatic gallstones to compare the clinical outcomes between the observation group (followed up with gallstones in situ) and the intervention group (cholecystectomy or cholecystolithotomy). The primary outcome was the composite of adverse outcomes, including gallstone-associated, gallbladder surgery-associated, and splenectomy-associated events. Secondary outcomes included the changes in the size and number of gallstones and the recurrence of gallstones. RESULTS Fifty-two patients were included (38 in the observation group and 14 in the intervention group), with a mean follow-up length of 5.2 years. Patients in the intervention group had a lower incidence of primary outcomes (7.1% vs. 42.1%) than patients in the observation group (OR, 0.12; 95%CI, 0.01-0.99). Patients with gallstones >5 mm in diameter had the highest risk of adverse events (47.4%). In the observation group, gallstone growth, disappearance, and stability were observed in 19.4%, 29.0%, and 51.6% of splenectomized HS patients, respectively. Small gallstones (diameter ≤5 mm) or sludge were more likely to be associated with disappearance (P = 0.04). CONCLUSIONS Most asymptomatic gallstones grow or persist in splenectomized HS patients for an extended period. Surgical treatment of asymptomatic gallstones in HS patients requiring splenectomy is associated with a lower risk of adverse outcomes. LEVELS OF EVIDENCE III (retrospective comparative study).

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.

Cost-effectiveness of endovascular repair, open repair, and conservative management of splenic artery aneurysms. J Vasc Surg 2015; 61:1432-40. [PMID: 25827968 DOI: 10.1016/j.jvs.2014.12.064] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2014] [Accepted: 12/21/2014] [Indexed: 12/14/2022]
Abstract
OBJECTIVE Open repair (OPEN) and conservative management (CONS) have been the treatments of choice for splenic artery aneurysms (SAAs) for many years. Endovascular repair (EV) has been increasingly used with good short-term results. In this study, we evaluated the cost-effectiveness of OPEN, EV, and CONS for the treatment of SAAs. METHODS A decision analysis model was developed using TreeAge Pro 2013 software (TreeAge Inc, Williamstown, Mass) to evaluate the cost-effectiveness of the different treatments for SAAs. A hypothetical cohort of 10,000 55-year-old female patients with SAAs was assessed in the reference-case analysis. Perioperative mortality, disease-specific mortality rates, complications, rupture risks, and reinterventions were retrieved from a recent and extensive meta-analysis. Costs were analyzed with the 2014 Medicare database. The willingness to pay was set to $60,000/quality-adjusted life years (QALYs). Outcomes evaluated were QALYs, costs from the health care perspective, and the incremental cost-effectiveness ratio (ICER). Extensive sensitivity analyses were performed and different clinical scenarios evaluated. Probabilistic sensitivity analysis was performed to include the uncertainty around the variables. A flowchart for clinical decision-making was developed. RESULTS For a 55-year-old female patient with a SAA, EV has the highest QALYs (11.32; 95% credibility interval [CI], 9.52-13.17), followed by OPEN (10.48; 95% CI, 8.75-12.25) and CONS (10.39; 95% CI, 8.96-11.87). The difference in effect for 55-year-old female patients between EV and OPEN is 0.84 QALY (95% CI, 0.42-1.34), comparable with 10 months in perfect health. EV is more effective and less costly than OPEN and more effective and more expensive compared with CONS, with an ICER of $17,154/QALY. Moreover, OPEN, with an ICER of $223,166/QALY, is not cost-effective compared with CONS. In elderly individuals (age >78 years), the ICER of EV vs CONS is $60,503/QALY and increases further with age, making EV no longer cost-effective. Very elderly patients (age >93 years) have higher QALYs and lower costs when treated with CONS. The EV group has the highest number of expected reinterventions, followed by CONS and OPEN, and the number of expected reinterventions decreases with age. CONCLUSIONS EV is the most cost-effective treatment for most patient groups with SAAs, independent of the sex and risk profile of the patient. EV is superior to OPEN, being both cost-saving and more effective in all age groups. Elderly patients should be considered for CONS, based on the high costs in relation to the very small gain in health when treated with EV. The very elderly should be treated with CONS.

Abstract
BACKGROUND/PURPOSE Expert guidelines recommend performing synchronous splenectomy in patients with mild hereditary spherocytosis (HS) and symptoms of gallstone disease. This recommendation has not been widely explored in the literature. The aim of this study is to determine if our data support expert opinion and if different practice patterns should exist. METHODS This is an IRB-approved retrospective study. All HS patients under 18 years of age who underwent cholecystectomy for symptomatic gallstones at a single institution between 1981 and 2009 were identified. Patients who underwent cholecystectomy without concurrent splenectomy were reviewed retrospectively for future need for splenectomy and evidence of recurrent gallstone disease. RESULTS Of the 32 patients identified, 27 underwent synchronous splenectomy. The remaining 5 patients underwent cholecystectomy without splenectomy and had a mean age of 9.4 years. One of the 5 patients eventually required splenectomy for left upper quadrant pain. None of the remaining 4 required hospitalization for symptoms related to hemolysis or hepatobiliary disease. Median follow-up is 15.6 years. CONCLUSION The need for splenectomy in patients with mild HS and symptomatic cholelithiasis should be assessed on a case by case basis. Our recommendation is to not perform synchronous splenectomy in conjunction with cholecystectomy for these patients if no indication for splenectomy exists.

Abstract
The presence of asymptomatic gallstones is no longer an indication for elective prophylactic cholecystectomy (PC) according to the recommendations of the 1991 French Consensus Conference on cholelithiasis. However, there may be potential benefits of performing prophylactic cholecystectomy during certain abdominal procedures for non-biliary disease; this remains a subject of debate. This debate has become livelier with the recent increase in bariatric surgery. Gastrectomy for cancer, small bowel resection, colonic resection, and splenectomy for hereditary spherocytosis as well as all bariatric surgical interventions can all alter the physiology of gallstone disease raising the question of the value of PC, but the specific morbidity of cholecystectomy must be kept in mind. The purpose of this study was to report epidemiological and pathophysiological data and the results from literature reports in order to assess the value of concomitant prophylactic cholecystectomy during various common surgical situations.

Abstract
CONTEXT little is known about the epidemiology of cholelithiasis in children. Cholelithiasis and choledocholithiasis were considered to be uncommon in infants and children but have been increasingly diagnosed in recent years due to wide- spread use of ultrasonography. However, there is not much of information from India and no consensus among Indian pediatricians and pediatric surgeons regarding management of gallstones in children. Hence, the purpose of this review is to increase awareness about the management of gallstones in children. METHODS extensive electronic (PubMed) literature search was made for this purpose and literature (original articles, clinical trials, case series, review articles) related to gallstones in children were reviewed. CONCLUSIONS the etiologies of cholelithiasis are hemolytic (20% -30%), other known etiology (40%-50%) such as total parenteral nutrition, ileal disease, congenital biliary diseases, and idiopathic (30-40 %). Spontaneous resolution of gallstones is frequent in infants and hence a period of observation is recommended even for choledocholithiasis. Children with gallstones can present with typical biliary symptoms (50%), nonspecific symptoms (25%), be asymptomatic (20%) or complicated (5% -10%). Cholecystectomy is useful in children with typical biliary symptoms but is not recommended in those with non-specific symptoms. Prophylactic cholecystectomy is recommended in children with hemolytic disorders.

Abstract
Patients with co-existing hereditary spherocytosis (HS) and UDP-glucuronosyltransferase 1A1 (UGT1A1) deficiency as Gilbert's syndrome (GS) have been reported, and previous studies have demonstrated an increased risk for developing gallstones in patients with co-inheritance of GS and HS. We experienced an interesting case of HS showing persistent jaundice after splenectomy, and upon further evaluation, the 25-year-old female patient was found to have HS combined with UGT1A1 deficiency. Sequence analysis of the UGT1A1 gene revealed that she was a compound heterozygote with p.[G71R; Y486D] + [Y486D] mutations, which suggests Crigler-Najjar syndrome type II rather than GS. Careful evaluation of inappropriately elevated bilirubin level compared with the degree of hemolysis is important, reflecting the therapeutic implication of splenectomy and cholecystectomy.

Abstract
Simultaneous presence of hemolytic anemia and bilirubin UDP-glucuronosyltransferase deficiency is a possible cause of misdiagnosis. Seven-year-old and 17-year-old brothers and a 15-year-old sister consecutively suffered from aplastic crises. Although few spherocytes were present, the siblings and their mother had diagnoses of hereditary spherocytosis with flow cytometric analysis of eosin-5'-maleimide-labeled red blood cells in addition to osmotic fragility test. However, inappropriately high values of bilirubin compared with mild hemolysis persisted. Further analysis of UDP-glucuronyltransferase 1A1 revealed all 3 siblings were heterozygous for A(TA)7TAA-P229Q. We report here the importance of careful evaluation of mild hereditary spherocytosis masking UDP-glucuronyltransferase 1A1 deficiency.

Abstract
Hereditary spherocytosis (HS) is the commonest inherited disorder of the erythrocyte membrane in Northern Europe and North America. It is marked by a regenerative anemia which varies widely from asymptomatic patients to severe hemolysis. In 75% of HS patients, inheritance is autosomal dominant. The diagnosis of HS is easily made when there are a family history, hemolytic anemia, reticulocytosis, spherocytes and increased hyperdense cells. Specialized testing to clarify the nature of membrane disorder is required when the film appearance is atypical without a positive family history, in the absence of a family history, in the newborn and before the splenectomy, to rule out the stomatocytosis which is contraindicated. The indication for splenectomy is dependent on the degree of anemia and its clinical manifestation.

Abstract
INTRODUCTION Partial splenectomy (PS) in children is a surgical option in haematological diseases and focal splenic tumours. The aim of this study was to describe the feasibility and the results of laparoscopic partial splenectomy in children in these two indications by a multicentric retrospective study. METHODS The authors reviewed the files of all children who underwent laparoscopic PS between March 2002 and September 2006 in two paediatric surgical centers. The data of 11 children were collected and included clinical presentation, age, gender, radiographic examinations, surgical procedure, need for blood transfusion and early complications. RESULTS From March 2002 to September 2006, laparoscopic PS had been performed on 11 children (6 boys, 5 girls) aged 23 months to 11 years (mean 7, 9). Four children had splenic focal tumours and seven had haematological diseases: six hereditary spherocytosis (HS) and one hemoglobinosis E. During the surgical procedure for haematological diseases 75-80% of the splenic tissue was removed. When PS was performed for focal splenic tumours, the splenic remnant was around 70%. No preoperative complications occurred (no bleeding, no diaphragmatic injury). Neither preoperative nor conversion was necessary. One postoperative complication occurred (left pleural effusion) but required no further treatment. The mean hospital stay was 7.7 days (range from 3 days to 10 days). No infectious postoperative complications occurred; the mean follow up was 21.1 months (range 3-52 months). CONCLUSION Laparoscopic partial splenectomy is feasible and safe in children with hypersplenism or focal splenic tumours. Partial splenectomy is a good way to prevent postsplenectomy infections by preservation of the immune role of spleen in children with haematological diseases. This technique performed for focal splenic tumours allows the surgeon to choose the size of the splenic remnant.

Abstract
Haemolytic anaemia is often induced following prolonged exposure to chemical substances. Currently, under EU Council Directive 67/548/EEC, substances which induce such effects are classified as dangerous and assigned the risk phrase R48 'Danger of serious damage to health by prolonged exposure.' Whilst the general classification criteria for this endpoint are outlined in Annex VI of this Directive, they do not provide specific information to assess haemolytic anaemia. This review produced by the EU Working Group on Haemolytic Anaemia provides a toxicological assessment of haemolytic anaemia and proposes criteria that can be used in the assessment for classification of substances which induce such effects. An overview of the primary and secondary effects of haemolytic anaemia which can occur in rodent repeated dose toxicity studies is given. A detailed analysis of the toxicological significance of such effects is then performed and correlated with the general classification criteria used for this endpoint. This review intends to give guidance when carrying out an assessment for classification for this endpoint and to allow for better transparency in the decision-making process on when to classify based on the presence of haemolytic anaemia in repeated dose toxicity studies. The extended classification criteria for haemolytic anaemia outlined in this review were accepted by the EU Commission Working Group on the Classification and Labelling of Dangerous Substances in September 2004.

Abstract
Hereditary spherocytosis (HS) is a heterogeneous group of disorders with regard to clinical severity, protein defects and mode of inheritance. It is relatively common in Caucasian populations; most affected individuals have mild or only moderate haemolysis. There is usually a family history, and a typical clinical and laboratory picture so that the diagnosis is often easily made without additional laboratory tests. Atypical cases may require measurement of erythrocyte membrane proteins to clarify the nature of the membrane disorder and in the absence of a family history, occasionally molecular genetic analysis will help to determine whether inheritance is recessive or non-dominant. It is particularly important to rule out stomatocytosis where splenectomy is contraindicated because of the thrombotic risk. Mild HS can be managed without folate supplements and does not require splenectomy. Moderately and severely affected individuals are likely to benefit from splenectomy, which should be performed after the age of 6 years and with appropriate counselling about the infection risk. In all cases careful dialogue between doctor, patient and the family is essential. Laparoscopic surgery, when performed by experienced surgeons, can result in a shorter hospital stay and less pain.

Abstract
The molecular causes of hereditary spherocytosis (HS) have been unraveled in the past decade. No frequent defect is found, and nearly every family has a unique mutation. In dominant HS, nonsense and frameshift mutations of ankyrin, band 3, and beta-spectrin predominate. Recessive HS is most often due to compound heterozygosity of defects in ankyrin, alpha-spectrin, or protein 4.2. Common combinations include a defect in the promoter or 5'-untranslated region of ankyrin paired with a missense mutation, a low expression allele of alpha-spectrin plus a missense mutation, and various mutations in the gene for protein 4.2. In most patients' red cells, no abnormal protein is present. Only rare missense mutations, like ankyrin Walsrode (V463I) or beta-spectrin Kissimmee (W202R), have given any insight into the functional domains of the respective proteins. Although the eminent role of the spleen in the premature hemolysis of red cells in HS is unquestioned, the molecular events that cause splenic conditioning of spherocytes are unclear. Electron micrographs show that small membrane vesicles are shed during the formation of spherocytes. Animal models give further insight into the pathogenetic consequences of membrane protein defects as well as the causes of the variability of disease severity.

Abstract
Congenital dyserythropoietic anemia type II (CDA II) is the most frequent type of congenital dyserythropoietic anemia. More than 200 cases have been described, but with the exception of a report by the International CDA II Registry, these reports include only small numbers of cases and no data on the lifetime evolution of the disease. Since 1967, we were able to follow 48 cases of CDA II from 43 families for up to 35 years. All patients exhibit chronic anemia of variable severity requiring regular red cell transfusions only in a minority of children; 60% developed gallstones before the age of 30 years, and 16 patients had cholecystectomy between 8 and 34 years of age. Iron overload was a frequent complication. In 16 cases, iron depletion started between 7 and 36 years. Three patients died from secondary hemochromatosis. Splenectomy, performed in 22 cases, led to moderate increases in hemoglobin values and eliminated the need for transfusions but did not prevent further iron loading. The current recommendation is to consider splenectomy if the anemia compromises patients' performance, and to manage iron overload according to the guidelines derived from patients with thalassemia.

Abstract
BACKGROUND/PURPOSE The aim of this report is to study the short- and long-term consequences of partial splenectomy (PS) in hereditary spherocytosis (HS). METHODS The authors reviewed the files of 5 children who underwent PS from 1993 to 1998. The data collected included clinical presentation, age, gender, indication for the operation, radiographic examination, need for blood transfusion and hematologic values, description of surgical procedure, and early- and late-occurring complications. RESULTS From 1993 to 1998, 5 children from one year, 9 months to 7 years of age underwent PS. Indications were hypersplenism and severe anemia. The average age at the time of the operation was 3 years, 5 months. The 2 youngest children (one year, 9 months and 2 years old) needed a second operation because of the recurrence of hypersplenism. CONCLUSIONS Subtotal splenectomy seems to preserve the immune role of the spleen and can reduce the need for blood transfusion. But PS is associated with a regrowth of the splenic remnant in children suffering from chronic hemolysis with hypersplenism and seems to be effective for a relatively short period only, especially in young children. Thus, a second operation to perform a total splenectomy can be necessary. The decision to perform a PS on young children with HS as an alternative to total splenectomy with appropriate preoperative vaccination and postoperative prophylactic antibiotics therefore should be weighed carefully, keeping in mind, however, the benefit of postponing total splenectomy in these patients.

Abstract
The aim of this paper is to point out the difference between static and dynamic approaches to choosing the optimal time for intervention. The paper demonstrates that classical approaches, such as decision trees and influence diagrams, hardly cope with dynamic problems: they cannot simulate all the real-world strategies and consequently can only calculate suboptimal solutions. A dynamic formalism based on Markov decision processes (MPPs) is then proposed and applied to a medical problem: the prophylactic surgery in mild hereditary spherocytosis. The paper compares the proposed approach with a static approach on the same medical problem. The policy provided by the dynamic approach achieved significant gain over the static policy by delaying the intervention time in some categories of patients. The calculations are carried out with DT-Planner, a graphical decision aid specifically built for dealing with dynamic decision processes.

Abstract
This paper addresses the relationship between hypertension and cognitive status and the impact of antihypertensive treatment. Data from cross-sectional and longitudinal studies are reviewed. After adjustment for age and level of education, cognitive function of hypertensive patients is impaired compared with the cognitive status of their nonhypertensive counterparts. The mechanisms underlying hypertension associated cognitive impairment remain to be elucidated. The role of antihypertensive treatment also has to be determined. Some evidence suggests that antihypertensive treatment may prevent dementia in hypertensive patients.
