Abstract
The spleen is a secondary lymphoid organ that belongs to the reticular-endothelial system, directly connected to blood circulation. The spleen is greatly involved in the immune response, especially against capsulated bacteria. Splenectomy plays a fundamental role in the treatment of numerous pediatric hematologic disorders. Taking into account all the possible complications (especially infections) linked to this procedure, alternatives to total splenectomy have been sought. Partial splenectomy has been proposed as a treatment that allows the reduction of infectious risk. This approach has proven safe and feasible in most patients, but multicentric and prospective studies are necessary to more accurately define the indications for performing partial splenectomy. However, vaccinations and antibiotic prophylaxis remain fundamental for preventing serious infections, even in the case of partial splenectomy. We review anatomical and functional properties of the spleen, with a focus on medical or surgical indications to splenectomy, aiming to give practical educational information to patients and their families after splenectomy. Furthermore, we discuss the feasibility of partial splenectomy in children with hematologic diseases who require splenectomy.

Abstract
BACKGROUND/PURPOSE In order to avoid consequences of total splenectomy (including severe postsplenectomy sepsis), partial splenectomy (PS) is increasingly reported. Without guidelines and indications concerning a rarely-indicated procedure, a review of literature should be an asset. METHODS A systematic review of all PSs from 1960 to December 2017 was performed, with special focus on surgical indications, sites of resection, approaches and techniques of vascular dissection and parenchymal section/hemostasis of the spleen, perioperative morbidity/mortality, including complications compelling to perform total splenectomy. RESULTS Among 2130 PSs, indications for resection were hematological disease in 1013 cases and nonhematological conditions in 1078, including various tumors in 142 and trauma in 184. Parenchymal transection was performed using several techniques through the years, most frequently after having induced partial ischemia by splenic hilum vascular dissection/ligation. 371 laparoscopic/robotic PSs were reported. Rescue total splenectomy was required in 75 patients. CONCLUSIONS Although good results are probably overestimated by such a retrospective review, PS should be considered as a procedure associated with a low morbidity/mortality. Nevertheless, severe complications are also reported, and the need of total splenectomy should not to be minimized. Laparoscopic/robotic procedures are increasingly performed, with good results and rare conversions. TYPE OF STUDY Systematic review. LEVEL OF EVIDENCE IV.

Abstract
Introduction Thalassemia is a common disease which treatment is often based on splenectomy. The risks associated with total splenectomy stimulated partial splenectomy as a potentially alternative therapy. Case presentation A 45 year-old female patient with long term follow-up for β thalassemia intermedia started to develop signs of hypersplenism and iron overload. A partial splenectomy was performed and was observed a marked hematologic improvement while preserving the desired splenic function. Discussion Partial splenectomy proved to provide a persistent decrease in hemolytic rate while preserving the integrity of splenic phagocytic function, presenting itself as an effective alternative to total splenectomy. After being subjected to partial splenectomy, our patient experienced a sustained control of hemolysis and showed no signs of hypersplenism or iron overload. No splenic regrowth or infectious complications were observed. The major drawbacks of partial splenectomy are the increased risk of intra- and postoperative bleeding, splenic remnant torsion and splenic regrowth. Conclusion Partial splenectomy is an alternative to total splenectomy for the treatment of adult β Thalassemia intermedia patients avoiding the risks associated with total splenectomy.

Abstract
To compare the clinical effectiveness of total splenectomy (TS) or partial splenectomy (PS) in pediatric hereditary spherocytosis, a systematic review and meta-analysis was performed (PROSPERO registration CRD42015030056). There were 14 observational studies comparing pre- and postoperative hematologic parameters. Secondary outcomes include in-hospital infections, surgical complications, symptomatic recurrence, and biliary disease. TS is more effective than PS to increase hemoglobin (3.6 g/dl vs. 2.2 g/dl) and reduce reticulocytes (12.5% vs. 6.5%) after 1 year; outcomes following PS are stable for at least 6 years. There were no cases of overwhelming postsplenectomy sepsis. A population-based patient registry is needed for long-term follow-up.

Abstract
Splenectomy is considered standard surgical therapy in hereditary spherocytosis. The procedure is indicated in patients with severe anemia, recurrent hemolytic, and aplastic crises. The aim of the study was to assess treatment outcomes in patients with hereditary spherocytosis who underwent total or partial laparoscopic splenectomy. Fifteen patients aged 4-17 yr underwent laparoscopic splenectomy from 2009 to 2012. Partial and total splenectomies were performed (five and 10 children, respectively). Hematologic parameters, liver function tests, and splenic volume before and after the surgery were analyzed retrospectively. Total follow-up was 1-30 months. Hospitalization and operating time were similar in both groups. In partial splenectomy group, branches of splenic arteries gave better blood supply than short gastric vessels. In both groups, hematologic parameters were improved. Postoperative markedly elevated platelet count was maintained up to 6 months, and after that, platelet count gradually decreased to normal values. Bilirubin level was decreased in early postoperative period; however, it increased later to achieve levels lower than in preoperative period. No severe general infections were observed in both groups. Laboratory parameters (hemoglobin and bilirubin concentrations and RBC) after the surgery improved in all patients, and the effect was maintained during 12 months of follow-up. Platelet count increased significantly after the surgery and was maintained at high levels during the next 6 months. However, it returned to preoperative levels within a year after the surgery. Our study showed that partial splenectomy was not inferior to total splenectomy. However, full assessment requires longer follow-up and larger group of patients.

Abstract
Over the last several decades, our understanding of the genetic variation, pathophysiology, and complications of the hemolytic anemia associated with red cell pyruvate kinase deficiency (PKD) has expanded. Nonetheless, there remain significant gaps in our knowledge with regard to clinical care and monitoring. Treatment remains supportive with phototherapy and/or exchange transfusion in the newborn period, regular or intermittent red cell transfusions in children and adults, and splenectomy to decrease transfusion requirements and/or anemia related symptoms. In this article, we review the clinical diversity of PKD, the current standard of treatment and for supportive care, the complications observed, and future treatment directions.Am. J.

Abstract
BACKGROUND Clinical outcomes of children with sickle cell disease (SCD) who undergo total or partial splenectomy (PS) are poorly defined. The purpose of this retrospective study was to initiate an Internet-based registry to facilitate analysis of clinical outcomes for these children. We hypothesized that both surgical procedures would be well tolerated and would eliminate risk of splenic sequestration. METHODS We developed a web-based registry using the Research Electronic Data Capture (REDCap) platform. Children were included if they had SCD and underwent total splenectomy (TS) or PS between 2003 and 2010. Clinical outcomes were compared between cohorts, with follow-up to 1 year. RESULTS Twenty-four children were included, TS (n = 15) and PS (n = 9). There were no differences in surgical time or intraoperative blood loss. The length of stay was longer after PS (4.1 ± 1.7 days) compared to TS, (2.4 ± 1.2 days, P = 0.02). Within 30 days of surgery, 2 (20%) patients had acute chest syndrome (ACS) following TS and 2 (15%) patients had ACS after PS. During 1-year follow-up, no patient in either cohort had recurrent splenic sequestration, venous thrombosis or overwhelming postsplenectomy sepsis. All children who were transfused preoperatively to prevent recurrent splenic sequestration successfully discontinued transfusions. CONCLUSIONS Both TS and PS result in favorable hematologic outcomes and low risk of adverse events for children with SCD. A REDCap-based registry may facilitate data entry and analysis of clinical outcomes to allow for comparison between different types of splenectomy.

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 We undertook the current study to update the literature on pediatric splenectomy in the age of minimally invasive proficiency among pediatric surgeons. The study is designed to address specific concerns among surgeons about the suitability of the laparoscopic approach in specific situations and among hematologists about the relative benefits and risks of splenectomy in children. METHODS Retrospective analysis of clinicopathologic data for 118 children who underwent open (OS) or laparoscopic (LS) splenectomy at an urban tertiary children's hospital from January 2000 to July 2008. RESULTS One hundred and three cases (87%) were started as LS. Operative times were equivalent for LS and OS (P = 0.8). In the LS group, there were four conversions (3.9%) from LS to OS and five early post-operative complications (4.9%). Median length of stay was 2 days for LS and 4 days for both OS and LS converted to OS (P < 0.0001). The ten largest spleens removed by LS had greater mass (P = 0.02) and tended to have greater volume (P = 0.1) than those removed by OS. Children with hereditary spherocytosis, ITP, and hemoglobinopathy had favorable clinical outcomes, regardless of operative approach. There were no cases of overwhelming post-splenectomy sepsis in this series. CONCLUSIONS Laparoscopic splenectomy is the preferred approach for splenectomy in children with hematological diseases, with or without splenomegaly. Compared to open splenectomy, laparoscopic splenectomy has equivalent operative time and improved length of stay. Both approaches have excellent therapeutic outcomes for appropriate indications.

Abstract
PURPOSE The mechanism by which partial splenectomy preserves splenic immune function is unknown. Immunoglobulin (Ig) M memory B cells are critical for the immune response against encapsulated bacteria and are reduced in asplenic patients, although it is unknown whether partial splenectomy can preserve memory B cells. We hypothesized that IgM memory B cells (murine B-1a cells) would be preserved after partial splenectomy but not after total splenectomy in mice. METHODS We performed total splenectomy (n = 17), partial splenectomy (n = 10), or sham laparotomy (n = 16) on C57BL/6J mice. Mice were killed on postoperative day 10 or 30, and peritoneal washings were analyzed by multiparameter flow cytometry for expression of murine B-1a cells (IgM(pos)IgD(dull)CD5(pos)B220(dull)). RESULTS We found that B-1a cells were significantly reduced after both total and partial splenectomies compared with sham laparotomy in the early postoperative period, although normal levels of B-1a cells returned by postoperative day 30 in mice undergoing partial splenectomy but not total splenectomy. CONCLUSION Partial splenectomy but not total splenectomy preserves the B-1a B-cell population in mice within 30 days after surgery. Maintenance of these critical B cells may contribute to the preservation of a splenic-dependent immune response after partial splenectomy.

Abstract
BACKGROUND Hematopoietic stem cell (HSC) engraftment is delayed after transplantation in children with hypersplenism, increasing the morbidity and costs of care. Preliminary clinical data suggest that splenectomy before HSC transplantation may improve HSC engraftment, although this observation has not been tested in an animal model. METHODS We performed total splenectomy (n = 22), partial splenectomy (n = 16), or sham laparotomy (n = 21) on erythrocyte protein 4.2 knockout mice, a murine model of hereditary spherocytosis with hypersplenism. After 10 days, we lethally irradiated the mice, transplanted 3 x 10(6) allogeneic bone marrow cells, and then assessed engraftment using serial complete blood counts. Successful engraftment was defined as recovery of hemoglobin, neutrophil, or platelet counts. We compared engraftment rate using chi(2) test and time to engraftment using Student's t test analysis, with significance defined as P < .05. RESULTS Total splenectomy increased the rate of successful HSC engraftment and decreased the interval to HSC engraftment compared with controls. Similarly, partial splenectomy decreased the interval to HSC engraftment, with a nonsignificant trend toward improved overall rate of successful HSC engraftment. CONCLUSION Partial or total splenectomy before HSC transplantation improves HSC engraftment in hypersplenic mice. This model supports consideration of splenic resection in hypersplenic children requiring HSC transplantation.

Abstract
PURPOSE Acute splenic sequestrations (SSs) are potentially fatal complications in sickle cell disease (SCD). Total splenectomies in young patients may predispose them to a higher risk of overwhelming infections, whereas partial splenectomy may maintain immunocompetence. We present our series of partial splenectomies in patients with multiple SS episodes. METHODS We retrospectively reviewed the records of 6 patients who underwent open partial splenectomies for SS. Data on their clinical courses were collected and analyzed. RESULTS None of the 6 patients had SS postprocedure, down from 2.1 +/- 1.0 (P = .003) sequestrations per year and 3.5 +/- 1.4 (P = .002) total sequestrations per patient. The transfusion requirements were significantly reduced postoperatively (10.2 +/- 5.6 vs 2.0 +/- 3.1 per year; P = .002). There was no increase in the infection-related hospital admissions during the period of follow-up (1.5 +/- 1.8 vs 0.8 +/- 0.8 per year after partial splenectomy; P = .363). The upper pole was preserved in all cases with blood supply off the main splenic artery. CONCLUSIONS Partial splenectomy decreases the risk of SS in SCD and reduces the need for blood transfusions. Infection rates did not increase after the procedure during the follow-up period. Partial splenectomy should be considered for patients who experience multiple acute SS crises or have long-term transfusion requirements.
