Abstract
Introduction: Massive splenomegaly in children can complicate minimally invasive splenectomy. Splenic artery embolization (SAE) before splenectomy has been shown to decrease splenic volume, reduce intraoperative blood loss, and decrease conversion rates in laparoscopic surgery. Our objective was to review our recent experience with immediate preoperative SAE in massive splenomegaly for pediatric patients using both laparoscopic and robotic techniques. Materials and Methods: We retrospectively reviewed preoperative SAE outcomes in pediatric patients with massive splenomegaly undergoing minimally invasive splenectomy between January 2018 and July 2021. Results: Four patients, 3 female, ages 5-18 years, had SAE immediately before minimally invasive splenectomy. Two cases were completed robotically, one laparoscopically, and one laparoscopic case required conversion to open. SAE time ranged from 69 to 92 minutes. Time between embolization and surgical start ranged from 26 to 56 minutes, with operative times from 153 to 317 minutes. Estimated blood loss ranged from <10 to 150 mL. Mean length of stay was 3.5 days (range 2-6). Postoperative complications included one patient with ileus and another with concurrent gastritis and urinary tract infection. Splenic size comparisons were difficult to perform due to morselization of the spleen; however, excised spleen weights, measurements, and surgeon's impression suggested decreased size of the spleen after SAE. There were no transfusions, postembolization complications, or deaths. Conclusion: SAE subjectively appears to decrease splenic distension, which should allow for easier manipulation and possibly better visualization of splenic hilar vessels during minimally invasive surgery. Immediate preoperative SAE is safe and feasible and should be considered in pediatric patients with massive splenomegaly.

Abstract
Background: We aimed to evaluate the outcomes of laparoscopic splenectomy (LS) in patients with immune thrombocytopenic purpura (ITP) compared with operated for other indications. Methods: Retrospective cohort study of patients who underwent LS in 1998-2017. Group 1 consisted of 256 patients operated for ITP, and Group 2 of 231 operated for other indications. Primary outcome was procedure difficulty. Secondary was perioperative course (30 days of surgery). Results: Patients in Group 1 were younger (p < .001) with lower ASA (p < .001). The spleen was larger in Group 2 (p < .001). Operative time was longer in Group 2 [110 (80-150) vs. 90 (65-115) min; p < .001)]. Intraoperative blood loss was greater in Group 2 (p < .001). Conversions were higher in Group 2 (4.76 vs. 6.93%, p = .037), as were intraoperative complications (7.79 vs. 3.91%, p = .048). Morbidity, reoperations and mortality did not differ between groups (respectively, p = .899, .697, and .999). Median length of stay was similar (p = .211). Among the first 10 LSs performed by trainees, 63.66% were done for ITP. Later (after 11+ procedures) this dropped to 48.12% (p = .002). Conclusions: ITP may be a preferred indication for surgeons training for LS. Patients' characteristics and intraoperative factors allow an expectation for a relatively easy and hassle-free operation in those patients.

Abstract
BACKGROUND The benefits of laparoscopic splenectomy (LS) over open splenectomy (OS) for normal-sized spleens have been well documented. However, the role of laparoscopy for moderate and massive splenomegaly is debated. METHODS A retrospective review of patients undergoing elective splenectomy at one institution from 1997 to 2017 was conducted. Moderate and massive splenomegaly was defined as splenic weight of 500-1000 g and greater than 1000 g, respectively. We performed a 1:2 matching of laparoscopic to open splenectomy to control for differences in splenic weight. Differences in perioperative morbidity (infection, thromboembolism, reoperation, readmission), intraoperative factors (blood loss, operative time), length of stay, and mortality were examined. RESULTS A total of 491 elective splenectomies were identified. 268 cases were for splenic weights greater than 500 g. After a 1:2 matching of LS:OS, we identified 22 LS and 44 matched OS for moderate splenomegaly. The LS group had longer mean operative times (178 vs. 107 min, p < 0.01), with similar length of stay and blood loss. For massive splenomegaly, 26 LS were identified and matched to 52 OS. LS had longer mean operative times (171 vs. 112 min, p < 0.01) and higher readmission rates (27% vs. 6%, p < 0.05). Other factors and outcomes did not differ between LS and OS for moderate or massive splenomegaly. The conversion rate for LS was higher for massive versus moderate splenomegaly, but was not statistically significant (35% vs. 14%, p = 0.09). CONCLUSIONS LS for moderate and massive splenomegaly is associated with longer operative times. Other perioperative outcomes were comparable to OS, with no demonstrated benefits for LS. Although LS may be a feasible approach to moderate and massive splenomegaly, its benefits require further clarification in this patient population.

Abstract
INTRODUCTION Since its first description by Delaitre and Maignien in 1991, laparoscopic splenectomy (LS) has evolved as treatment of choice for mild-to-moderately-enlarged spleens and for benign haematological disorders. LS is a challenge if massive spleens or malignant conditions necessitate treatment, but we report our method and its feasibility in this study. METHODS We undertook a retrospective study of prospectively collected data of all elective splenectomies carried out in our firm of upper gastrointestinal surgeons from June 2003 to June 2012. Only patients opting for elective LS were included in this study. RESULTS From June 2003 to June 2012, elective splenectomy was carried out in 80 patients. Sixty-seven patients underwent LS and 13 underwent open splenectomy (OS). In the LS group, there were 38 males and 29 females. Age ranged from 6 years to 82 years. Spleen size in the LS group ranged from ≤11 cm to 27.6 cm. Twelve patients had a spleen size of >20 cm. Weight ranged from 35 g to 2,400 g. Eighteen patients had a spleen weight of 600-1,600 g and eight had a spleen weight >1,600 g. Operating times were available for 56 patients. Mean operating time for massive spleens was 129.73 min. There was no conversion to OS. There were no major complications. CONCLUSIONS With improved laparoscopic expertise and advancing technology, LS is safe and feasible even for massive spleens and splenic malignancies. It is the emerging 'gold standard' for all elective splenectomies and has very few contraindications.

Abstract
BACKGROUND The current laparoscopic splenectomy (LS) procedure used for cirrhotic patients still has limitations. The aim of our study was to determine a standard according to the splenic size for hand-assisted LS (HALS) in patients with splenomegaly and hypersplenism due to cirrhosis. PATIENTS AND METHODS We conducted a retrospectively review of cirrhotic patients who underwent splenectomy between 2008 and 2011. All patients were divided into two groups: Group A (19 patients), in which patients' operations were conducted by HALS, and Group B (20 patients), in which patients were treated with LS. Then the patients in Group A were classified on the basis of the spleen size: massive splenomegaly (Group A1) and supramassive splenomegaly (Group A2). Likewise, so were patients in Group B: massive splenomegaly (Group B1) and supramassive splenomegaly (Group B2). Perioperative outcomes of these patients were compared. RESULTS The comparison of HALS and LS based on spleen size demonstrated that in the massive splenomegaly groups, Group A1 and Group B1 had similar estimated blood loss and morbidity, and no transfusion was required in these patients. In the supramassive splenomegaly groups, compared with Group A2, Group B2 had longer operative time, more estimated blood loss, more patients requiring transfusion, and more complications that needed surgical intervention. However, no significant differences were observed in the requirement of analgesia, time of returning to oral intake, and length of hospitalization in these paired groups. CONCLUSIONS In cirrhotic patients with supramassive splenomegaly, HALS should be considered because of its safety, feasibility, and effectiveness.

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
In the last few years, the use of laparoscopy in veterinary medicine has expanded and consequently so was the need for studies that establish the advantages, disadvantages and possible complications of each procedure. The purpose of the current study was to describe a laparoscopic splenectomy technique and the alterations due to this access, and compare it to the open procedure in dogs. A total of 15 healthy female mongrel dogs were used, with mean weight of 17.4±2.5kg. The animals were distributed into three groups: Group IA of open splenectomy (laparotomy) using double ligation of the vessels of the splenic hilum with poliglicolic acid, Group IB of open splenectomy (laparotomy) with bipolar electrocoagulation of the splenic hilum, and Group II of laparoscopic access with bipolar electrocoagulation of the splenic hilum. Operative time, blood loss, size of incisions, complications during and after surgery were evaluated. Other parameters included pain scores, white blood cell (WBC) counts and postoperative serum concentrations of alanine aminotransferase (ALT), alkaline phosphatase (ALP), creatine kinase (CK), C-reactive protein (CRP), glucose and cortisol. No differences were found in the evaluation of parameters between both open splenectomy techniques employed. Laparoscopic access presented significant differences (p<0,05) when compared with open surgery: Longer operative time, smaller abdominal access, decrease in blood loss, lower concentrations of CRP, higher levels of CK and ALP, and lower scores in the pain scale. Laparoscopic surgery showed fewer complications of the surgical wound. No significant differences were observed between groups in the postoperative temperature, WBC, ALT, cortisol and glucose concentrations. In conclusion, the laparoscopic technique is useful for splenectomy in dogs, being advantageous in terms of blood loss, surgical stress and surgical wounds. However, it expends more operative time and causes transitory increase in hepatic and muscular enzymes.

Abstract
BACKGROUND Although laparoscopic splenectomy (LS) has become the standard approach for most splenectomy cases, some areas still remain controversial. To date, the indications that preclude laparoscopic splenectomy are not clearly defined. In view of this, the European Association for Endoscopic Surgery (EAES) has developed clinical practice guidelines for LS. METHODS An international expert panel was invited to appraise the current literature and to develop evidence-based recommendations. A consensus development conference using a nominal group process convened in May 2007. Its recommendations were presented at the annual EAES congress in Athens, Greece, on 5 July 2007 for discussion and further input. After a further Delphi process between the experts, the final recommendations were agreed upon. RESULTS Laparoscopic splenectomy is indicated for most benign and malignant hematologic diseases independently of the patient's age and body weight. Preoperative investigation is recommended for obtaining information on spleen size and volume as well as the presence of accessory splenic tissue. Preoperative vaccination against meningococcal, pneumococcal, and Haemophilus influenzae type B infections is recommended in elective cases. Perioperative anticoagulant prophylaxis with subcutaneous heparin should be administered to all patients and prolonged anticoagulant prophylaxis to high-risk patients. The choice of approach (supine [anterior], semilateral or lateral) is left to the surgeon's preference and concomitant conditions. In cases of massive splenomegaly, the hand-assisted technique should be considered to avoid conversion to open surgery and to reduce complication rates. The expert panel still considered portal hypertension and major medical comorbidities as contraindications to LS. CONCLUSION Despite a lack of level 1 evidence, LS is a safe and advantageous procedure in experienced hands that has displaced open surgery for almost all indications. To support the clinical evidence, further randomized controlled trials on different issues are mandatory.

Abstract
BACKGROUND Clinical manifestations of hereditary spherocytosis can be controlled by splenectomy. The use of this procedure has been restricted due to concerns regarding exposure of patients to a lifelong risk of overwhelming infections. Subtotal splenectomy, which removes 85-90% of the enlarged spleen, is a logical alternative. In the first cases performed by laparoscopy we have chosen to preserve the upper pole. However, this technique showed some disadvantages, especially concerning the correct intraoperative evaluation of the splenic remnant volume. Therefore, we developed a new variant of the procedure by preserving the lower pole of the spleen. METHODS Based on the authors' experience in laparoscopy (176 laparoscopic splenectomies), 10 laparoscopic subtotal splenectomies were performed in patients with hereditary microspherocytosis, preserving either the upper or the lower splenic pole. RESULTS Patient age ranged between 5 and 35 years. The mean volume of the remnant spleen was 41.4 cm3. There were no complications, and no transfusions were needed. Follow-up for 1-30 months was available. CONCLUSIONS Subtotal splenectomy appears to control hemolysis while maintaining splenic function. The laparoscopic approach is safe and effective and should be considered the procedure of choice in hereditary microspherocytosis. Laparoscopic subtotal splenectomy presents an advantage over open subtotal splenectomy, resulting in decreased blood loss, shorter hospital stay, no conversions, fewer operative and postoperative complications, and excellent remission rates. On the basis of our experience, the preservation of the lower pole of the spleen seems to be a first-line option for the optimal evaluation of the residual splenic mass.

Abstract
BACKGROUND Comparisons of splenic size based on splenic weight are difficult after laparoscopic splenectomy, which results in a morcellated specimen. We report the results of a direct comparison between morcellated and intact splenic weights. METHODS Porcine spleens were harvested via a midline laparotomy, and an intact splenic weight was obtained, which served as the control. The spleen then was placed into an impermeable retrieval bag and returned to the peritoneal cavity. A separate 10-mm incision was made and the spleen mechanically morcellated with a uterine forceps. This design most faithfully recreates the morcellation process during laparoscopic splenectomy in humans. The aggregate weight of the fragments was compared with intact splenic weight. RESULTS Intact and morcellated weights were obtained from 58 porcine spleens. The mean intact splenic weight was 145 g, and the mean morcellated weight was 78 g. For a given morcellated weight achieved at laparoscopic splenectomy, an estimated intact weight can be determined by the following formula: intact weight (g) = morcellated weight (g) x 1.34 + 45. CONCLUSIONS On the basis of our calculations, a normal spleen weighing 150 g would have a mean morcellated weight of 78 g, and splenomegaly (intact spleen weighing 250 g or more) would be defined by a morcellated weight exceeding 153 g.
