Abstract
Sickle cell disease (SCD) is caused by a point mutation in the beta-globin gene. SCD is characterized by chronic hemolytic anemia, vaso-occlusive events leading to tissue ischemia, and progressive organ failure. Chronic inflammatory state is part of the pathophysiology of SCD. Patients with SCD have extremely variable phenotypes, from mild disease to severe complications including early age death. The spleen is commonly injured in SCD. Early splenic dysfunction and progressive spleen atrophy are common. Splenomegaly and hypersplenism can also occur with the loss of the crucial splenic function. Acute, life-threatening spleen-related complications in SCD are well studied. The association of laboratory parameters with the spleen status including hyposplenism, asplenia, and splenomegaly/hypersplenism, and their implication in vaso-occlusive crisis and long-term complications in SCD remain to be determined. We evaluated the association between the spleen status with clinical and laboratory parameters in 31 SCD patients: Group a) Patients with asplenia/hyposplenism (N = 22) (including auto-splenectomy and splenectomized patients) vs. Group b) patients with splenomegaly and or hypersplenism (N = 9). Laboratory studies included: Complete Blood Count, reticulocyte count, iron metabolism parameters, C Reactive Protein (CRP), Hb variant distribution, and D-dimer. Metabolic and morphological red blood cell (RBC) studies included: density gradient (by Percoll), glucose consumption, lactate release, and K+ leakage, fetal RBC (F-Cells) and F-Reticulocytes, annexinV+, CD71+, oxidative stress measured by GSH presence in RBC and finally Howell Jolly Bodies count were all analyzed by Flow Cytometry. Scanning electron microscopy analysis of RBC was also performed. Patients with asplenia/hyposplenism showed significantly higher WBC, platelet, Hematocrit, hemoglobin S, CRP, D-dimer, Gamma Glutamyl Transferase (GGT), cholesterol, transferrin, annexin V+ RBCs, CD71+ RBCs, together with a markedly lower F Reticulocyte levels in comparison with splenomegaly/hypersplenism patients. In summary, important differences were also found between the groups in the studied RBCs parameters. Further studies are required to elucidate the effect of the spleen including hyper and hypo-splenia on laboratory parameters and in clinical manifestations, vascular pathology, and long-term complications of SCD. The benefits and risks of splenectomy compared to chronic transfusion need to be evaluated in clinical trials and the standard approach managing hypersplenism in SCD patients should be re-evaluated.

Abstract
INTRODUCTION Despite its wide acceptance, the superiority of laparoscopic versus open pediatric surgery has remained controversial. There is still a call for well-founded evidence. We reviewed the literature on studies published in the last three decades and dealing with advantages and disadvantages of laparoscopy compared to open surgery. MATERIALS AND METHODS Studies comparing laparoscopic versus open abdominal procedures in children were searched in PubMed/MEDLINE. Reports on upper and lower gastrointestinal as hepatobiliary surgery and on surgery of pancreas and spleen were included. Advantages and disadvantages of laparoscopic surgery were analyzed for different types of procedures. Complications were categorized using the Clavien-Dindo classification. RESULTS A total of 239 studies dealing with 19 types of procedures and outcomes in 929,157 patients were analyzed. We identified 26 randomized controlled trials (10.8%) and 213 comparative studies (89.2%). The most frequently reported advantage of laparoscopy was shorter hospital stay in 60.4% of studies. Longer operative time was the most frequently reported disadvantage of laparoscopy in 52.7% of studies. Clavien-Dindo grade I to III complications (mild-moderate) were less frequently identified in laparoscopic compared to open procedures (80.3% of studies). Grade-IV complications (severe) were less frequently reported after laparoscopic versus open appendectomy for perforated appendicitis and more frequently after laparoscopic Kasai's portoenterostomy. We identified a decreased frequency of reporting on advantages after laparoscopy and increased reporting on disadvantages for all surgery types over the decades. CONCLUSION Laparoscopic compared with open pediatric surgery seems to be beneficial in most types of procedures. The number of randomized controlled trials (RCTs) remains limited. However, the number of reports on disadvantages increased during the past decades.

Abstract
Abstract
Background
The purpose of this paper is to evaluate the feasibility, safety, efficacy, benefits, and outcome of elective laparoscopic splenectomy for children younger than 5 years with sickle cell disease (SCD) who needed splenectomy. We conducted a retrospective review for a prospective data on patients younger than 5 years with SCD requiring splenectomy from January 2007 to June 2019. Patients were evaluated with regard to patient demographics, operative time, presence of accessory spleens, blood loss, length of hospital stay, morbidity, mortality, and clinical outcome.
Results
A total of 71 patients younger than 5 years with SCD underwent laparoscopic splenectomy (LS) at our institution from January 2007 to June 2019. There were 28 boys and 43 girls. The age at LS is from 2 years to less than 5 years (mean 3.2 years). The mean operating time was 65 min. There was no conversion to open surgery; all the cases were successfully performed laparoscopically. Twelve patients (17%) underwent a concomitant cholecystectomy. The hospital stay ranged from 2 to 6 days (median, 3 days). The mean follow-up was 86 months (range, 17 to 161 months). Postoperative follow-up revealed no cases of overwhelming postsplenectomy sepsis infection (OPSI).
Conclusion
Laparoscopic splenectomy in young children less than 5 years of age with sickle cell disease is a safe and effective treatment. When patients are given preoperative vaccination and penicillin prophylaxis, OPSI rarely occurs.

Abstract
The majority of the global population of sickle cell disease (SCD) patients resides in Africa. Individuals with this condition are at great risk of serious infections and early mortality secondary to splenic dysfunction without preventative measures. This review investigated the spectrum of splenic complications encountered in SCD among populations in Africa. We systematically searched several databases for all articles published through March 3, 2020. We included 55 studies from 14 African countries. This review reveals the difference in frequency of splenic complications in SCD in Africa when compared with their counterparts in the United State and Europe. While several studies (n = 45) described splenomegaly with a prevalence of 12% to 73% among children, and 4% to 50% among adults with HbSS, the reported prevalence for acute splenic sequestration crisis (n = 6 studies) and hypersplenism (n = 4 studies) was <10% and <5% respectively. A total of 30 surgical splenectomy was reported across eight studies. Only two (3.7%) studies provided data on spleen function. A conflicting pattern was observed amongst studies that evaluated the relationship between splenomegaly and the presence of bacterial and malaria infections. This review reveals the paucity of studies describing the role of SCD-induced splenic dysfunction in morbidity and infection related mortality in Africa.

Abstract
Hereditary hemolytic anemias are a group of disorders with a variety of causes, including red cell membrane defects, red blood cell enzyme disorders, congenital dyserythropoietic anemias, thalassemia syndromes and hemoglobinopathies. As damaged red blood cells passing through the red pulp of the spleen are removed by splenic macrophages, splenectomy is one possible therapeutic approach to the management of severely affected patients. However, except for hereditary spherocytosis for which the effectiveness of splenectomy has been well documented, the efficacy of splenectomy in other anemias within this group has yet to be determined and there are concerns regarding short- and long-term infectious and thrombotic complications. In light of the priorities identified by the European Hematology Association Roadmap we generated specific recommendations for each disorder, except thalassemia syndromes for which there are other, recent guidelines. Our recommendations are intended to enable clinicians to achieve better informed decisions on disease management by splenectomy, on the type of splenectomy and the possible consequences. As no randomized clinical trials, case control or cohort studies regarding splenectomy in these disorders were found in the literature, recommendations for each disease were based on expert opinion and were subsequently critically revised and modified by the Splenectomy in Rare Anemias Study Group, which includes hematologists caring for both adults and children.

Abstract
BACKGROUND: Sickle cell disease is a common genetic disease in Saudi Arabia; it is an autosomal recessive disorder characterized by production of abnormal hemoglobin S and is associated with high morbidity and mortality. Acute splenic sequestration is a life-threatening complication for this disease. Prophylactic splenectomy is the only effective strategy for preventing future life-threatening episodes. AIM: The aim of this study was to study hospital records for all children aged 2 to 12 year old with Sickle cell disease who underwent splenectomy in Tabuk in Saudi Arabia. METHODS: Records of 24 children (13 males, 11 females) who underwent splenectomy in surgery department of King Salman North West Armed Hospital, Tabuk, Saudi Arabia between 2008 and 2015 were reviewed retrospectively and analyzed for age, sex, indications for splenectomy, surgical technique, preoperative and postoperative length of stay, operative and postoperative complications, acute chest syndrome, painful crises, blood transfusion and fever (preoperative and postoperative). RESULTS: We stressed on the information about the details of operation, the frequency of blood transfusion, fever, acute chest syndrome and painful crisis before and after operation. CONCLUSION: Here we found that blood transfusion frequency decreased after splenectomy.

Abstract
PURPOSE We conducted a systematic review and meta-analysis to compare the clinical outcomes between laparoscopic splenectomy and the traditional open splenectomy in children. METHODS Literature searches were conducted to identify studies having compared the laparoscopic splenectomy (LS) and open splenectomy (OS) for children. Parameters such as operative time, blood loss, length of postoperative stay, the removal of accessory spleens and postoperative complications including postoperative high fever, acute chest syndrome (ACS), and ileus were pooled and compared by meta-analysis. RESULTS Among the 922 pediatric participants included in the 10 studies, 508 had received LS and 414 OS. There were shorter length of hospital stays, less blood loss, and longer operative times with the LS approach compared with OS. However, no significant difference was found between LS and OS in the secondary outcome, such as the removal of accessory spleens or postoperative complications including postoperative high fever, ACS, and ileus. CONCLUSION LS is a feasible, safe, and effective surgical procedure alternative to OS for pediatric patients. Compared with OS, LS has the advantage of shorter hospital stay and less blood loss. Besides, total postoperative complications may be slightly lower in LS. We conclude that LS should be considered an acceptable option for children.

Abstract
Splenectomy, while often necessary in otherwise healthy patients after major trauma, finds its primary indication for patients with underlying malignant or nonmalignant hematologic diseases. Indications of splenectomy for hematologic diseases have been reducing in the last few years, due to improved diagnostic and therapeutic tools. In high-income countries, there is a clear decrease over calendar time in the incidence of all indication splenectomy except nonmalignant hematologic diseases. However, splenectomy, even if with different modalities including laparoscopic splenectomy and partial splenectomy, continue to be a current surgical practice both in nonmalignant hematologic diseases, such as Immune Thrombocytopenic Purpura (ITP), Autoimmune Hemolytic Anemia (AIHA), Congenital Hemolytic Anemia such as Spherocytosis, Sickle Cell Anemia and Thalassemia and Malignant Hematological Disease, such as lymphoma. Today millions of people in the world are splenectomized. Splenectomy, independently of its cause, induces an early and late increase in the incidence of venous thromboembolism and infections. Infections remain the most dangerous complication of splenectomy. After splenectomy, the levels of antibody are preserved but there is a loss of memory B cells against pneumococcus and tetanus, and the loss of marginal zone monocytes deputed to immunological defense from capsulated bacteria. Commonly, the infections strictly correlated to the absence of the spleen or a decreased or absent splenic function are due to encapsulated bacteria that are the most virulent pathogens in this set of patients. Vaccination with polysaccharide and conjugate vaccines again Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis should be performed before the splenectomy. This practice reduces but does not eliminate the occurrence of overwhelming infections due to capsulated bacteria. At present, most of infections found in splenectomized patients are due to Gram-negative (G-) bacteria. The underlying disease is the most important factor in determining the frequency and severity of infections. So, splenectomy for malignant diseases has the major risk of infections.

Abstract
The study assessed changes in cerebral blood flow and need for chronic blood transfusions in sickle cell disease children after splenectomy. A retrospective chart review of 40 children splenectomized between 1999 and 2014 was performed. The mean time-average maximum velocity before splenectomy was 129 cm/sec; which increased to 157 cm/sec and then decreased to 137 cm/sec, 2 and 5 years postsplenectomy, respectively. There was a persistent and statistically significant elevation in platelet count noted after splenectomy. The mean cerebral blood flow velocity seemed to increase transiently after splenectomy. Close monitoring and screening for stroke risk should be continued postsplenectomy.

Abstract
OBJECTIVE: To evaluate the frequency of infectious complications in children with sickle
cell disease (SCD) after surgical splenectomy for acute splenic sequestration
crisis. METHODS: Retrospective cohort of children with SCD who were born after 2002 and were
regularly monitored until July 2013. Patients were divided into two groups: cases
(children with SCD who underwent surgical splenectomy after an episode of splenic
sequestration) and controls (children with SCD who did not have splenic
sequestration and surgical procedures), in order to compare the frequency of
invasive infections (sepsis, meningitis, bacteremia with positive blood cultures,
acute chest syndrome and/or pneumonia) by data collected from medical records.
Data were analyzed by descriptive statistical analysis. RESULTS: 44 patients were included in the case group. The mean age at the time of
splenectomy was 2.6 years (1-6.9 years) and the mean postoperative length of
follow-up was 6.1 years (3.8-9.9 years). The control group consisted of 69
patients with a mean age at the initial follow-up visit of 5.6 months (1-49
months) and a mean length of follow-up of 7.2 years (4-10.3 years).All children
received pneumococcal conjugate vaccine. No significant difference was observed
between groups in relation to infections during the follow-up. CONCLUSIONS: Surgical splenectomy in children with sickle cell disease that had splenic
sequestration did not affect the frequency of infectious complications during 6
years of clinical follow-up.

Historically, splenectomy before 5 years of age was avoided because of fear of overwhelming postsplenectomy sepsis. Recently, splenectomy has been performed as early as 2 years of age, but the safety of this approach is unknown. This study compared outcomes of splenectomy performed in patients under 5 years of age with those 5 years of age and older. MATERIALS AND METHODS A retrospective chart review of patients registered in a children's hospital hematology database was performed to examine intraoperative and postoperative outcomes after splenectomy. Statistical data analysis included Fisher's exact tests for categorical variables and the nonparametric median test for continuous variables. RESULTS From 1997 to 2012, 30 sickle cell patients underwent splenectomy. At surgery, 18 of the 30 patients were under 5 years of age (Group 1), and 12 patients were 5 years of age or older (Group 2). Almost all procedures were laparoscopic. Both group had similar operative times, rates of conversion, and frequencies of complications. Both groups had similar lengths of follow-up (median, 62 months for Group 1 versus 63 months for Group 2). No portal vein thromboses or postsplenectomy sepsis events occurred in either group. CONCLUSIONS In this study, there was no evidence that the incidence of complications was higher after splenectomy at a younger age. A large, multicenter study is needed to further evaluate the safety of this practice.

Comparative effectiveness of different types of splenectomy for children with congenital hemolytic anemias. J Pediatr 2012; 160:684-689.e13. [PMID: 22050869 DOI: 10.1016/j.jpeds.2011.09.030] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2011] [Revised: 08/31/2011] [Accepted: 09/19/2011] [Indexed: 01/11/2023]
Abstract
OBJECTIVE To compare the effectiveness of different types of splenectomy in children with congenital hemolytic anemias. STUDY DESIGN We constructed key questions that addressed outcomes relevant to clinicians and families on effects of partial or total splenectomy, including hematologic effect, splenic function, and the risk of adverse events. We identified from Pubmed and Embase 703 studies that evaluated different types of splenectomy and accepted 93 studies that satisfied entry criteria. We graded the quality of each report and summarized the overall strength of research evidence for each key question. RESULTS We did not identify any randomized clinical trials. All types of splenectomy have favorable clinical outcomes in most diseases. We did not identify any hematologic advantage of laparoscopy compared with laparotomy. Adverse events are uncommon in most studies and are minimized with use of laparoscopy. CONCLUSIONS There is a need for randomized clinical trials and improved data collection of different types of splenectomy in congenital hemolytic anemias. Outcomes studied should address the concerns of families and clinicians to assess the risks and benefits of various treatments.

Abstract
PURPOSE Despite advances in immune prophylaxis, sepsis remains the most feared complication following splenectomy for acute splenic sequestration crisis (ASSC) in children with sickle cell anemia (SCA). We seek to investigate the true prevalence of sepsis and other complications of splenectomy in this patient population. METHODS We reviewed the records of children with SCA (HbSS) who underwent splenectomy for ASSC between 1993 and 2008 at a single institution. RESULTS Fifty-eight patients (33 males) at a median age of 2 years at splenectomy were included with an average post-splenectomy follow-up of 6.4 years (range 6 months-14 years). Thirty-seven patients (64%) underwent laparoscopic splenectomy, and acute chest syndrome (ACS) was the most common post-operative complication (6.9%). There was no difference in the incidence of sepsis pre- and post-splenectomy. The occurrence of vaso-occlusive pain crises (VOC) and ACS was significantly higher after splenectomy. In addition, 14 patients (24%) developed stroke (n = 5) or an abnormal transcranial Doppler (TCD) (n = 9) after splenectomy. CONCLUSION Our data suggest that splenectomy can be safely performed in children with SCA given a low risk of sepsis. However, the increased incidence of VOC, ACS, and stroke or abnormal TCDs after splenectomy remains a concern.

[PMID: 19695352 DOI: 10.1016/j.ijsu.2009.08.004] [Citation(s) in RCA: 13] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2009] [Revised: 07/13/2009] [Accepted: 08/07/2009] [Indexed: 10/20/2022]
Abstract
BACKGROUND Haematological disorders, in particular sickle cell disease (SCD) and thalassaemia, are relatively common in Oman. We report our experience of splenectomy for haematological disorders and review the literature on splenectomy role in their management. OBJECTIVES To review our experience in the management of 150 patients with haematological disorders undergoing splenectomy with emphasis on indications and outcome. To compare our experience with those reported from outside this region. METHODS The records of 150 patients who underwent splenectomy over a thirteen year period were reviewed retrospectively, analyzing the age and sex of the patients, indication for splenectomy, operative procedures, complications, peri-operative management and outcome. RESULTS Of the 150 patients, 96 (64%) had SCD and 34 (22.6%) had beta-thalassaemia; the rest comprised patients with refractory idiopathic thrombocytopenic purpura (ITP) n=12, hereditary spherocytosis (HS) n=6, and auto-immune haemolytic anaemia (AHA) n=2. In SCD patients, the main indications for splenectomy were recurrent splenic sequestration (60.4%) and hypersplenism (36.4%), whereas in thalassaemic patients it was increased requirement of packed red blood cells (PRBC) transfusion (mean 310 ml, range 242-372 of PRBC/kg/year). All patients received prophylactic antibiotics and vaccination against pneumococcal infection and when the vaccine was available for Haemophilus influenzae. PRBC and platelet concentrates as well as intravenous fluids were infused preoperatively as per protocol. Concomitant procedures at laparotomy included liver biopsy (14.6%) and cholecystectomy (8.6%). The postoperative morbidity was low (8.6%) and there was no mortality. All patients were maintained on long term penicillin and proguanil, and the mean follow-up was 4.6 years. In SCD patients splenectomy eliminated the risks of life threatening acute splenic sequestration and improved significantly the blood counts of the hypersplenic cases, while in thalassaemic patients it reduced significantly the mean transfusion requirement by 100ml PRBC/kg/year (p<0.0001). Of the patients with refractory ITP, two thirds had a good response to splenectomy (p<0.0001). All HS and AHA patients benefited from splenectomy. CONCLUSION The predominant indications for splenectomy were recurrent acute splenic sequestration and hypersplenism in SCD patients, and increased transfusion demand in the thalassaemics. Overall, splenectomy proved beneficial in eliminating the risk of splenic sequestration in SCD patients, in improving the blood counts in SCD with hypersplenism and in reducing transfusion requirement in thalassaemic patients, while in ITP group two thirds of the patients benefited.
