Guizzetti L. Temporal trends of splenectomy in pediatric hospitalizations with hereditary spherocytosis from 2000 to 2019: A national survey. Pediatr Blood Cancer 2024; 71:e30869. [PMID: 38316689 DOI: 10.1002/pbc.30869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 12/15/2023] [Accepted: 01/01/2024] [Indexed: 02/07/2024]
Abstract
BACKGROUND Total and partial splenectomy are used in pediatric patients with hereditary spherocytosis to resolve anemia and hemolytic complications. PROCEDURE Data from the Healthcare Cost and Utilization Project's Kid's Inpatient Database was used to profile and describe temporal trends in pediatric (≤18 years) hospital admissions in the United States from 2000 to 2019 data release years. Survey sampling methods were used to produce national estimates. RESULTS From 2000 to 2019, the use of splenectomy declined overall, from 427 to 206 weighted procedures (difference = 222, 95% confidence interval [CI]: 124-320; p < .0001); the risk of undergoing splenectomy during admission also declined from 56.7% to 38.7% (risk difference = 17.9 percentage points [p.p.], 95% CI: 9.7-26.1; p < .0001). Total splenectomy was mostly used. Age at time of splenectomy increased 10.2 years (difference = 1.6 years, 95% CI: 0.6-2.7; p = .0018). The risk of splenectomy increased with age until 10 years, then leveled off until 18 years. The proportion of children aged ≤5 years undergoing splenectomy decreased from 27.7% to 11.2% in 2019 (risk difference: 16.5 p.p., 95% CI: 7.3-25.7; p = .0004). The strongest clinical predictors of splenectomy, adjusting for patient- and hospital-level characteristics, were a co-diagnosis of symptomatic cholelithiasis (adjusted odds ratio [aOR] = 3.18, 95% CI: 1.92-5.28; p < .0001) and splenomegaly or hypersplenism (aOR = 2.52, 95% CI: 1.74-3.65; p < .0001). Risk of splenectomy with splenomegaly or hypersplenism increased over time. CONCLUSION Splenectomy was delayed until age greater than 10 years. Older age, co-diagnosis with splenomegaly or hypersplenism, or symptomatic cholelithiasis were strongest clinical predictors of splenectomy. Conservative management of hereditary spherocytosis appears to be more common.

Abstract
Background: The introduction of splenectomy in pediatric robotic surgery programs remains controversial. The aim of this study is to evaluate the feasibility and safety of robotic assisted splenectomy (RAS) in children and compare its outcomes with the laparoscopic splenectomy (LAS). Method: A single institution retrospective study was performed (2011-2020). We used the minimally invasive splenectomy score described by Giza et al. to measure the level of technical difficulty. The data collected for each procedure included its duration, the need for blood transfusion, complications, analgesic use, and the length of hospital stay. A standard univariate analysis is applied. Results: We recorded 41 cases (26 LAS and 15 RAS). The mean age was 11 years [7.00; 13.5]. The operating time was 97 minutes [85.5-108] for LAS and 223 minutes [190-280] for RAS (P < .001). The length of stay was 6.50 days [5.00-8.00] for LAS and 5 days [5.00-5.50] for RAS (P = .055). The cumulative use of level III analgesic was not statically different (P = .29). Two cases of difficult splenectomy were found in each group with comparable performances. In the RAS, we demonstrated the improved outcomes with the progression of the learning curve of a single surgeon. Conclusions: In our experience (as in the literature), RAS remains safe, but offers no additional advantage compared to laparoscopy as the cost and the operating time are higher. Our study has the advantages of having a 9 years long evolving experience, including broad indications in comparison to other pediatric studies.

Abstract
PURPOSE Partial, or subtotal, splenectomy (PS) has become an accepted alternative to total splenectomy (TS) for management of hematologic disorders in children, but little is known about its long-term outcomes. Here, we present our institutional experience with partial splenectomy, to determine rate of subsequent TS or cholecystectomy and identify if any factors affected this need. METHODS All patients who underwent partial splenectomy at a single tertiary children's hospital were retrospectively reviewed from 2002 through 2019 after IRB approval. Primary outcome of interest was rate of reoperation to completion splenectomy (CS) and rate of cholecystectomy. Secondary outcome were positive predictor(s) for these subsequent procedures. RESULTS Twenty-four patients underwent PS, at median age 6.0 years, with preoperative spleen size of 12.7 cm by ultrasound. At median follow up time of 8.0 years, 29% of all patients and 24% of hereditary spherocytosis (HS) patients underwent completion splenectomy at median 34 months and 45 months, respectively. Amongst HS patients who did not have a cholecystectomy with or prior to PS, 39% underwent a delayed cholecystectomy following PS. There were no significant differences in age at index procedure, preoperative splenic volume, weight of splenic specimen removed, transfusion requirements, preoperative or postoperative hematologic parameters (including hemoglobin, hematocrit, total bilirubin, and reticulocyte count) amongst patients of all diagnoses and HS only who underwent PS alone compared to those who went on to CS. There were no cases of OPSS or deaths. CONCLUSION Partial splenectomy is a safe alternative to total splenectomy in children with hematologic disease with theoretical decreased susceptibility to OPSS. However, families should be counseled of a 29% chance of reoperation to completion splenectomy, and, in HS patients, a 39% chance of delayed cholecystectomy if not performed prior to or with PS. Further studies are needed to understand predictors of these outcomes.

Abstract
Purpose: We performed a retrospective study to determine the effectiveness and feasibility of articulating linear stapler in laparoscopic total splenectomy (LTS) and laparoscopic partial splenectomy (LPS), focusing on technical laparoscopic skills that could help pediatric surgeons to avoid intra- and postoperative complications. Methods: Retrospective cohort study of children younger than 18 years who underwent laparoscopic spleen surgery between January 2008 and March 2020. Age, sex, indication for surgery, operative time (OT), intra- and postoperative complications, and postoperative length of hospital stay (LHS) were analyzed. Data from parenchymal resection and vessels sealing techniques were obtained. Results: Thirty patients, 19 LTS and 11 LPS, were included. The mean age of the patients was 10.9 years, and 16 patients were male and 14 were female. For hematologic diseases, LTS was the elective surgery, associated with cholecystectomy in 5 cases. LPS was the common procedure for splenic cysts. The stapler was used in LTS to close the hilum vessels and in LPS for parenchymal resection. No statistically significant differences in OT were observed comparing LTS and LPS. Two conversions occurred in LTS; none in LPS. The mean LHS was 6 days in both groups. No recurrence or major complications appeared in both groups at 1-12 years of follow-up. In particular for LPS, there are no relapse of cyst neither reduction in splenic function. Conclusions: This study shows the effectiveness, feasibility, and safety of mechanic stapler in splenic surgery both for hilum vessels sealing and for parenchymal resection. The use of this device can reduce risk of hemorrhagic recurrences or major surgical complications improving the safety of the operation.

Abstract
Background: Laparoscopic partial splenectomy (LPS) may allow avoiding total splenectomy (TS) complications and maximizing the advantages of mini-invasive approach. The objective of this review is to assess feasibility and safety of LPS, to compare this approach with alternative options. Materials and Methods: A literature review of articles reporting LPS is performed. Several parameters, including age, indication, surgical technique, devices used for splenic section/hemostasis, adverse outcomes, including morbidity/mortality, conversions to open surgery, conversions to TS, operative time (OT), and hospital stay (HS), are analyzed. Articles comparing LPS' results with those of open partial splenectomy and laparoscopic TS are also analyzed. Results: Fifty-nine articles reporting 457 LPS were included. Patients' characteristics varied widely, concerning age and indications, including hematological disease (hereditary spherocytosis, drepanocytosis), splenic focal masses, and trauma. Several technical options are reported. Mean OT and HS are 128 ± 43.7 minutes and 4.9 ± 3.8 days, respectively. No mortality and 5.7% morbidity are reported. Conversion rates to open surgery and to TS are 3.9% and 3.7%, respectively. Conclusions: In conclusion LPS is feasible and safe, with no mortality, low morbidity, and low conversion rates to laparotomy and to TS. LPS may be accomplished by various techniques and tools. Major complications are sporadically reported, thus potential risks should not be underestimated.

Abstract
BACKGROUND To summarise the clinical features of Sclerosing angiomatoid nodular transformation (SANT) of the spleen and to compare the efficacy of three different surgical treatments. METHODS We performed a retrospective analysis of patients with SANT of spleen treated at our center from 2009 to 2018. We compared the efficacy and safety of three different types of surgical procedures. ANOVA and the chi-square test were used for statistical analysis. RESULTS A total of 37 patients were included. Most (35/37; 94.6%) were asymptomatic. A number presented as obscure boundary lesions such that malignancy could not be excluded. Open splenectomy was performed for 12 patients, laparoscopic splenectomy for 12 patients and laparoscopic partial splenectomy for 13 patients. Operation time (P = 0.355), blood loss (P = 0.135), length of hospital stay after operation (P = 0.271) and postoperative complications (P = 0.502) were comparable between the three groups. Duration of drainage tube placement was significantly longer in laparoscopic partial splenectomy patients (P = 0.006). Peak platelet count after operation was significantly lower in laparoscopic partial splenectomy patients (P < 0.001). CONCLUSION Laparoscopic partial splenectomy appears to be a technically feasible and therapeutically effective approach for SANT.

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
Four children (two boys and two girls), aged from 3 years and 7 months to 5 years, had mild or moderate anemia, mild hepatosplenomegaly, jaundice (mainly an increase in indirect bilirubin), an increase in the percentages of reticulocytes and spherical erythrocytes in peripheral blood smear and an increase in erythrocyte osmotic brittleness. High-throughput sequencing found two novel mutations in the SLC4A1 gene, c.37G>A and c.340T>C, in case 1 and case 2 respectively, and these two mutations were predicted to be pathogenic by Mutation Taster. The Polyphen2 scores of these two mutations were 0.87 and 0.83 respectively, which suggested that these mutations were probably damaging. The SIFT scores of these two mutations were 0.008 and 0.09 respectively, suggesting that these mutations were probably damaging. No abnormality in this gene was found in their parents. Two reported heterozygous mutations in the ANK1 gene, c.830A>G and c.985G>C, were found in case 3 and case 4 respectively. Gene detection was not performed for the parents of case 3. The mother of case 4 was diagnosed with hereditary spherocytosis and had a heterozygous mutation of c.985G>C in the ANK1 gene. All four children were diagnosed with hereditary spherocytosis. Case 3 had a hemoglobin level of <80 g/L and underwent splenectomy at the age of 5 years and 6 months, and regular postoperative reexamination showed a hemoglobin level of >105 g/L. Hereditary spherocytosis is a hereditary hemolytic disease caused by abnormality in erythrocyte membrane protein, and gene detection helps to make a confirmed diagnosis.

Abstract
BACKGROUND Laparoscopic partial splenectomy (LPS) theoretically maintains long-term splenic immune function for children with hereditary spherocytosis (HS). Our goal was to review our results after LPS and to determine if specific genetic mutations influence outcome. METHODS All children with HS undergoing LPS between 2005 and 2016 were reviewed. RESULTS Thirty-one children underwent LPS (16 male) at a median age of 9 (range 2-18) years. All experienced an increase in hemoglobin and decrease in reticulocyte count early after LPS and at last follow-up. Twenty-two were sent for genetic analysis. Mutations in α-spectrin, β-spectrin, and Ankyrin were identified in 6, 5, and 11 patients, respectively. Gene mutation was not correlated with complications, perioperative transfusion, length of hospital stay, or median hemoglobin, platelet, or reticulocyte counts. Three children required completion splenectomy at 10.9, 6.9, and 3.2years post-LPS, each with a different gene mutation. CONCLUSIONS LPS is effective in reversing anemia and reducing reticulocytosis. So far less than 10% have required completion splenectomy, and those children did benefit from delaying the risks of asplenia. In this preliminary analysis, genetic mutation did not influence outcome after LPS. A larger multicenter study is necessary to further investigate potential correlations with specific genetic mutations. TYPE OF STUDY Prognosis Study. LEVEL OF EVIDENCE IV.

Abstract
Background The erythrocytic stage, where malaria parasites proliferate in human blood, is clinically significant as this causes the symptoms and illness of malaria. Experimental rodent models of malaria at the erythrocytic stage are used for the development of anti-malarial drugs and for biological analysis. An automated haematology analyzer XN-30 was developed for detection of infected red blood cells (iRBCs) in human blood samples and measurement of their parasitaemia in approximately 1 min through flow cytometry analysis. Additionally, the analyzer simultaneously measured other haematological parameters in these samples. It is inferred that the analyzer would also allow easy and rapid measurement of parasitaemia in mice and provide important clues on the mouse haematological state during infection and treatment. Results The XN-30 analyzer is a simple and rapid tool to detect iRBCs in mouse blood samples infected with rodent malarial parasites, with three-dimensional analysis permitting the precise measurement of parasitaemia (referred herein as the ‘XN-30 system’). The XN-30 analyzer allowed not only the detection of iRBCs but also the monitoring of RBC, white blood cell, and platelet counts, as well as haematocrit, mean corpuscular volume and mean platelet volume values in the mouse blood sample. For anti-malarial drug development, aside from demonstrating possible efficacy in mouse models, XN-30 analyzer could provide a first glimpse of the safety profile of the drug. Conclusions The XN-30 system is a powerful tool that can be utilized for the in vivo screening, development, and evaluation of anti-malarial drugs as well as for pre-clinical pharmacology and/or toxicity tests in rodent models.

Abstract
BACKGROUND Splenic injury can occur through multiple mechanisms and may result in various degrees of residual immunocompetence. Functionally or anatomically asplenic patients are at higher risk for infection, particularly with encapsulated bacteria. Vaccination is recommended to prevent infection with these organisms; however, the recommendations are routinely updated, and vaccine selection and timing are complex. METHODS Review of the pertinent English-language literature, including the recommendations of the U.S. Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices. RESULTS Overwhelming post-splenectomy infection is associated with high morbidity and mortality rates. Patients requiring splenectomy for trauma-related injury appear to be at lower risk for infection than those undergoing splenectomy for a hematologic or oncologic indication. Initial vaccination is dependent on immunization history but generally should consist of the 13-valent pneumococcal conjugate, quadrivalent meningococcal conjugate, meningococcal serogroup B, and Haemophilus influenzae serotype b (Hib) vaccines. Antimicrobial prophylaxis for certain asplenic patients, such as children under the age of five y, may be indicated. CONCLUSION Immunization remains a key measure to prevent overwhelming post-splenectomy infection. Consideration of new recommendations and indications, possible interactions, and timing remains important to including optimal response to the vaccines.

Subtotal Splenectomy in Hereditary Spherocytosis - Advantages and Disadvantages. CURRENT HEALTH SCIENCES JOURNAL 2016; 42:408-412.

Abstract
Hereditary spherocytosis (HS) represents the most frequent hemolytic anemia in Central and Northern Europe consisting in an inherited abnormality of the red blood cell (RBC) membrane. It is usually transmitted as an autosomal dominant disorder; 25% of cases are without family history. Splenectomy is the classical conception and it can cure hemolysis, being the treatment of choice for moderate to severe forms of HS. A new approach is accepted nowadays, subtotal splenectomy, thus eliminating the lifelong risk of postsplenectomy infections. We present two cases of HS treated by subtotal splenectomy, alongside the advantages and disadvantages of this therapy.

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
PURPOSE The purpose of this study was to define the hematologic response to total splenectomy (TS) or partial splenectomy (PS) in children with hereditary spherocytosis (HS) or sickle cell disease (SCD). METHODS The Splenectomy in Congenital Hemolytic Anemia (SICHA) consortium registry collected hematologic outcomes of children with CHA undergoing TS or PS to 1 year after surgery. Using random effects mixed modeling, we evaluated the association of operative type with change in hemoglobin, reticulocyte counts, and bilirubin. We also compared laparoscopic to open splenectomy. RESULTS The analysis included 130 children, with 62.3% (n=81) undergoing TS. For children with HS, all hematologic measures improved after TS, including a 4.1g/dl increase in hemoglobin. Hematologic parameters also improved after PS, although the response was less robust (hemoglobin increase 2.4 g/dl, p<0.001). For children with SCD, there was no change in hemoglobin. Laparoscopy was not associated with differences in hematologic outcomes compared to open. TS and laparoscopy were associated with shorter length of stay. CONCLUSION Children with HS have an excellent hematologic response after TS or PS, although the hematologic response is more robust following TS. Children with SCD have smaller changes in their hematologic parameters. These data offer guidance to families and clinicians considering TS or PS.

Abstract
BACKGROUND Partial splenectomy is preferred to total splenectomy when possible to reduce the risk of life-threatening infection. Several techniques have been described, each with its merits. Laparoscopic transection with monopolar saline-cooled radiofrequency coagulation has not been previously described. PATIENTS AND METHODS Two patients with enlarging cystic splenic lesions consented to laparoscopic partial splenectomy. In 1 case, high-power saline-cooled monopolar radiofrequency transection was performed with a laparoscopic sealing hook; the procedure was performed with a rigid resectoscope and ball diathermy in the other. RESULTS Both cases were performed without complications. Transection with the resectoscope and ball diathermy was combined with selective clamping of the splenic hilar vessels and was performed in 100 minutes with estimated blood loss of 250 mL. Transection with the sealing hook was performed in 80 minutes without hilar vessel clamping, with an estimated blood loss of 100 mL. No additional hemostatic agents were required for either case. CONCLUSIONS Laparoscopic partial splenectomy can be performed with monopolar saline-cooled radiofrequency for parenchymal transection and hemostasis in a simple and effective manner.
