Splenic torsion is a rare phenomenon characterised by a twisting of the spleen along its vascular pedicle, typically in the setting of lax suspensory ligaments. It is more commonly encountered in the paediatric population; however, it also has been documented in the adult population. Management is not well described due to its rarity. We illustrate a case of a paraplegic male in his 50s who presented with progressive abdominal pain and was found to have splenic torsion with suspected infarction on imaging. This was managed successfully with splenectomy., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024. No commercial re-use. See rights and permissions.

Three cases of giant, nonparasitic splenic cysts in young patients are presented. The cysts were poorly-symptomatic and manifested with mild upper-abdominal pain and discrete change of abdominal contour. The diagnosis was made based on USG and abdominal CT. Upon operation, the cysts were successfully excised, sparing almost the whole spleen, using standard instruments: electric knife and LigaSure instrument. The postoperative course was uneventful in all cases. At the 4-6-months follow-up, all patients were in good shape and CT showed no signs of recurrence. The results of this case series show that giant splenic cysts may be relatively safely resected, sparing almost the whole spleen.

Background: Concomitant laparoscopic splenectomy and cholecystectomy (CLSC) is performed for concurrent pathologies of the spleen and gallbladder. This systematic review aimed to evaluate the available evidence on its indications, operative technique, and outcomes. Materials and Methods: The PubMed and Cochrane bibliographical databases were searched from the beginning of time (last search: December 6, 2019) for studies reporting on CLSC. The National Heart, Lung, and Blood Institute (NHLBI) quality assessment tool was utilized for the evaluation of eligible articles. Results: Eight studies met inclusion criteria and concerned collectively 108 patients (53 males and 55 females) with a mean age of 27.02 ± 20.48 years (mean, SD). The most common surgery indications were hereditary spherocytosis (38.9%) and sickle cell disease or β-thalassemia (32.4%). Laparoscopic cholecystectomy preceded splenectomy in the majority of cases (75%). A five-trocar approach was most frequently (89.8%) utilized. The mean operation duration was 170.18 ± 53.07 minutes (mean, SD). Resected spleen weight was 601.82 ± 386.02 g (mean, SD) and had a length of 18.74 ± 5.3 cm (mean, SD). The conversion rate was 2.7%, while 20.4% of included cases experienced postoperative complications. Most frequent ones included pulmonary infection (6.5%) and portal/splenic vein thrombosis (4.6%). No postoperative death was recorded. Mean hospitalization period was 5.43 ± 3.18 days (mean, SD). Conclusions: CLSC is a safe and feasible operation for simultaneous diseases of the spleen and gallbladder that require elective procedures. High-quality clinical trials are essential to further elucidate clinical evidence and standardize operative technique.

Solid pseudopapillary tumours of the pancreas and giant splenic cysts are very rare entities, and their coexistence in a young female patient has not been previously reported in the literature. We present the case of a 27-year-old woman who presented with abdominal pain and two masses on abdominal imaging. A mass located in the right upper quadrant was biopsied, and histological and immunohistochemical analysis showed a solid pseudopapillary tumour of the pancreas. A giant cystic splenic lesion was also noted. The patient underwent a distal pancreatectomy and splenectomy in our referral centre. Margins were negative on histopathological examination. Negative surgical margins were achieved with distal pancreatectomy and splenectomy despite the large size of the pancreatic tumour. The management of solid pseudopapillary tumours of the pancreas is often challenging and the concomitant presence of a giant splenic cyst poses additional challenges to the surgical management of such tumours.

The aim of this work was to review the entire literature on splenic surgery in cirrhotic patients in order to best define the surgical indications and their management specifics. A review of the international literature published between January 1995 and August 2015 was thus carried out., (Celsius.)

Splenic cysts are a rare pathology, which can be classified as true (25%) or pseudocysts (75%). Total splenectomy has been the treatment of choice, particularly in recent times with the advent of the laparoscopic approach. However, as the spleen is an organ with multiple immunological functions, the laparoscopic partial splenectomy is an alternative, which is technically difficult but effective. We present a case of a 26-year-old woman with incidental evidence of a splenic cyst in an abdominal ultrasound scan. We performed a laparoscopic partial splenectomy to preserve the function of the spleen because of the patient's youth. Laparoscopic partial splenectomy allows the effective removal of lesions and preservation of splenic function. Although more research is needed to clarify the most effective approach, this case is further evidence that this surgical approach may be beneficial for selected patients.

Laparoscopic splenectomy is now established as a safe and feasible procedure. However, it remains associated with some short- and long-term postoperative complications, especially infectious complications. To our knowledge, this is the first report (with video) focusing on the safety and feasibility of laparoscopic hemi-splenectomy and its surgical outcomes for the treatment of splenic abscesses causing septic emboli. This technique combines the immunological benefits of partial splenectomy and the postoperative benefits of a minimally invasive approach. Further studies are needed to standardize this technique and to assess its immunological and surgical benefits.

Introduction: Laparoscopic splenectomy (LS) is the gold standard for the treatment of many spleen-related disorders. However, in the presence of splenomegaly, the rate of conversion to open surgery can be as high as 33.9% and is associated with longer operative times and higher costs. In an attempt to improve risk stratification and patient selection for LS, a score that includes four preoperative parameters (age, gender, diagnosis, and spleen size) has been developed. The aim was the validation of a difficulty grading score, in predicting conversion and poorer outcomes., Methods: Retrospective analysis of 153 consecutive patients subjected to LS from January 2006 through December 2016 was performed. Several parameters were reviewed and correlation with evaluated outcomes was analyzed., Results: Conversion to open surgery occurred in 13 (8.50%) patients and was highly associated with serious intraoperative complications. Spearman correlation showed a significant association between the score and risk of conversion, operative time, and postoperative complications, but not with intraoperative bleeding., Discussion: Patient and disease features, incorporated in a difficulty grading score, can reliably determine the difficulty of LS and predict risk of conversion, intraoperative, and postoperative complications. This simple and reproducible score improves risk stratification for LS and could be practical in daily clinical activities.

People with asplenia/hyposplenism are at increased risk of fulminant sepsis, which carries a high mortality rate. A range of preventive measures is recommended although there is ongoing evidence that knowledge of and adherence to these strategies is poor. There have been significant changes in recommended vaccinations since the previously published recommendations in 2008. We provide current recommendations to help Australian and New Zealand clinicians in the prevention of sepsis in patients with asplenia and hyposplenia. The guideline includes Australian epidemiological data, preferred diagnostic techniques and recommendations for optimal antimicrobial prophylaxis and vaccination protocols., (© 2017 Royal Australasian College of Physicians.)

Background: Hamartoma is a slow-growing, rare mixed benign tumor. In general, it does not produce symptoms, so it is more commonly found as an incidentaloma during autopsies or laparotomies. Incidence of splenic hamartomas is low, representing 0.001% of the general population., Clinical Case: We report the case of a 39 year-old male without relevant antecedents. The evolution of his condition began 2 months prior with pyrosis and occasional pain in the upper hemi-abdomen. Abdominal ultrasound demonstrated a pseudocystic tumor in the spleen. Magnetic resonance showed four lesions in the spleen, predominating a large, bilobulated lesion in the inferior pole of 12 × 10 × 9 cm. A splenectomy was done without complications and the patient was discharged to home at third postoperative day. Pathological report showed a splenic hamartoma., Conclusions: Hamartomas of the spleen as in other localizations are benign lesions found as incidentalomas because only few produce symptoms. The final diagnosis is made histopathologically. Definitive treatment is splenectomy and treatment of choice is complete laparoscopic transabdominal splenectomy. Although there are few incidences in Mexico, it is of vital importance that the physician considers it among the differential diagnoses when evaluating a tumor.

Background and Objectives: The aim of this study was to evaluate the results of laparoscopic surgery performed for coexisting spleen and gallbladder surgical diseases., Methods: Between May 2004 and October 2012, 12 patients underwent concomitant laparoscopic splenectomy and cholecystectomy. Indications for surgery included idiopathic thrombocytopenic purpura in 5 patients, hereditary spherocytosis in 4 patients, and thalassemia intermedia in 3 patients., Results: The mean operative time was 100 minutes (range, 80 -160 minutes), and the blood loss ranged from 0 to 150 mL (mean, 50 mL). The mean longitudinal diameter of the spleen was 14 cm. One patient required conversion to open procedure. An accessory spleen was detected and removed in one case. The mean length of hospital stay was 5 days. No deaths or other major intraoperative and/or postoperative complications occurred., Conclusion: Provided that the technique is performed by an experienced surgical team, concomitant laparoscopic splenectomy and cholecystectomy is a safe and feasible procedure and may be considered for coexisting spleen and gallbladder diseases.

Non-parasitic splenic cysts are relatively rare, and the optimal surgical treatment for them remains controversial. Laparoscopic unroofing is a relatively safe and easy technique, but a significant number of recurrences has been reported. Thus, complete cystectomy with partial splenectomy is recommended by several surgeons. However, patients sometimes suffer from intraoperative bleeding. Here, we report a patient with a giant non-parasitic splenic cyst who underwent subtotal cystectomy with partial splenectomy. After the dissection of the vessels circulating the upper pole at the splenic hilum, the resection line of the splenic parenchyma was on the ischemic side of the cyanotic demarcation line. A vessel sealing system and laparoscopic coagulation shears were used for the resection. We intentionally left about 10% of the cyst wall to avoid bleeding from the non-ischemic splenic parenchyma and remaining vessels. No recurrence has been detected after 6 months of observation. We believe this method could be a useful alternative procedure for the treatment of non-parasitic splenic cysts and preservation of the splenic parenchyma., (© 2013 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.)

Objective: To examine the occurrence, disease course, prognosis, and vaccination status of patients with community-acquired bacterial meningitis with a history of splenectomy or functional hyposplenia., Patients and Methods: Patients with bacterial meningitis proven by cerebrospinal fluid culture were prospectively included in a nationwide cohort study between March 1, 2006, and September 1, 2011. Splenectomy or diseases associated with functional hyposplenia were scored for all patients. Vaccination status, clinical features, and outcome of patients with a history of splenectomy or functional hyposplenia were analyzed and compared with patients with normal spleen function., Results: Twenty-four of 965 patients (2.5%) had an abnormal splenic function: 16 had a history of splenectomy and 8 had functional hyposplenia. All patients had pneumococcal meningitis. Pre-illness vaccination status could be retrieved for 19 of 21 patients (90%), and only 6 patients (32%) were adequately vaccinated against pneumococci. Pneumococcal serotype was known in 21 patients; 52% of pneumococcal isolates had a serotype included in the 23-valent vaccine. Vaccine failure occurred in 3 patients. Splenectomized patients more often presented with signs of septic shock compared with patients with a normal spleen (63% vs 24%; P=.02). Outcome was unfavorable in 14 patients (58%), and 6 patients died (25%)., Conclusion: Splenectomy or functional hyposplenia is an uncommon risk factor for bacterial meningitis but results in a high rate of mortality and unfavorable outcome. Most patients were not adequately vaccinated against Streptococcus pneumoniae., (Copyright © 2013 Mayo Foundation for Medical Education and Research. Published by Elsevier Inc. All rights reserved.)

Background: This study was designed to compare the laparoscopic subtotal splenectomy with the robotic approach in patients with hereditary spherocytosis., Methods: Thirty-two consecutive subtotal splenectomies by minimal approach in patients with hereditary spherocytosis were analyzed (10 robotic vs. 22 laparoscopic subtotal splenectomies)., Results: A significant difference was found for the robotic approach regarding blood loss, vascular dissection duration, and splenic remnant size. Follow-up for 4-103 months was available., Conclusions: Subtotal splenectomy seems to be a suitable candidate for robotic surgery, requiring a delicate dissection of the splenic vessels and a correct intraoperative evaluation of the splenic remnant. Robotic subtotal splenectomy is comparable to laparoscopy in terms of hospital stay and complication. The main benefits are lower blood loss rate, vascular dissection time, and a better evaluation of the splenic remnant volume.

Patient aged 66 years, was admitted for splenomegaly grade III/IV, haematological hypersplenism and medium / large secondary anemia, diagnosed in the hematology clinic, where a myeloproliferative syndrome was denied. Was performed splenectomy, splenic lodge toilet and drainage. Histopathology was established the diagnosis of splenic sarcoidosis. Good postoperative evolution. Main issues discussed are etiopathogeny, diagnostic and therapeutic, that this rare disease of unknown etiology is giving., (RevistaChirurgia.)

Each year, up to a 1000 splenectomies are performed in the Netherlands. Aside from patients without a spleen, there is also a large group of patients with hyposplenism or functional asplenia due to other primary diseases. All these patients are at risk of developing severe infections, such as post-splenectomy sepsis (PSS), which is associated with very high mortality. However PSS can partly be prevented by taking simple measures such as immunizations and prophylactic or early use of antibiotics. Healthcare professionals in first and secondary care in the Netherlands are generally not well informed about which preventive measures should be taken to prevent these infections, resulting in often suboptimal management of patients. In this article, recommendations are given on vaccination and administration of antibiotics to prevent severe infections such as PSS in this group of patients.

Background: A significant number of patients with schistosomiasis develop the hepatosplenic form, with portal hypertension, in which bleeding caused by rupture of esophagogastric varices emerged as the leading cause of morbidity and mortality., Aim: To investigate the effects of splenectomy and ligature of the left gastric vein on risk factors for bleeding of esophagogastric varices in patients with schistosomiasis mansoni, hepatosplenic form, with a history of upper gastrointestinal bleeding., Methods: The main risk factors of bleeding from esophagogastric varices were studied in 34 patients. The following parameters were investigated: 1) esophageal variceal pressure, measured by the endoscopic pneumatic balloon technique; 2) size, fundamental color, extension and red signs of esophageal varices, gastric varices and gastropathy of portal hypertension. The evaluations were performed in the preoperative period, immediate postoperative period (between the sixth and eighth postoperative days) and the sixth month of follow-up., Results: The variceal pressure has fallen from 22.3+/-2.6 mmHg before surgery to 16.0+/-3.0 mmHg in the immediate postoperative period (p<0.001), reaching 13.3+/- 2.6 mmHg in the sixth month of follow-up. A significant reduction of the frequency of the parameters associated with a greater risk of hemorrhage was observed between the preoperative period and six-month follow-up, when the proportion of large esophageal varices (p<0.05), varices extending to the upper esophagus (p<0.05), bluish varices (p<0.01), varices with red signs (p<0.01) and gastropathy (p<0.05) decreased., Conclusion: In patients with hepatosplenic schistosomiasis with a previous history of variceal hemorrhage, splenectomy and gastric vein ligation was effective in reducing the main hemorrhagic risk factors until the sixth month of follow-up, indicating a good way to control the bleeding episodes.

We herein describe a case of successful surgical treatment of isolated splenic peliosis presenting with giant splenomegaly and severe coagulopathy. Pathological features of the spleen included multinodular, blood-filled, cyst-like lesions distributed throughout the whole organ. The pathogenesis of isolated splenic peliosis is controversial, and no definitive disease mechanism has been reported. To our knowledge, this is the first report in English of a case like this., (Copyright © 2011 Elsevier Inc. All rights reserved.)

The spleen is crucial in regulating immune homoeostasis through its ability to link innate and adaptive immunity and in protecting against infections. The impairment of splenic function is defined as hyposplenism, an acquired disorder caused by several haematological and immunological diseases. The term asplenia refers to the absence of the spleen, a condition that is rarely congenital and mostly post-surgical. Although hyposplenism and asplenia might predispose individuals to thromboembolic events, in this Review we focus on infectious complications, which are the most widely recognised consequences of these states. Because of the high mortality, the fulminant course, and the refractoriness to common treatment of overwhelming infections caused by encapsulated bacteria, prevention through vaccination and antibiotic prophylaxis is the basis of the management of patients who have had splenectomy or have hyposplenism. In this Review, we critically assess clinical and diagnostic aspects of splenic dysfunction and highlight new perspectives in the prevention of overwhelming post-splenectomy infections., (Copyright © 2011 Elsevier Ltd.

Background/aim: Primary splenic cysts are relatively uncommon and in the majority of cases are classified as epithelial cysts which are more frequent in young patients. Most of them are asymptomatic, and they are found incidentally during imaging techniques or laparotomy. We report two rare cases of patients with epithelial splenic cysts as an incidental finding during emergency laparotomy for splenic rupture., Materials and Method: The first patient was a 70-year-old man who presented with symptoms of acute abdomen after intensive cough during an episode of asthma. Emergency laparotomy findings were splenic rupture and intraperitoneal haemorrhage. A splenectomy was performed and the histological examination showed a ruptured spleen with an epithelial cyst. The second patient was a 19-year-old man who was transferred to the Emergency Department in hypovolemic shock due to intraperitoneal bleeding after a blunt abdominal injury. During laparotomy a splenic rupture was found, and an epithelial cyst., Conclusion: Epithelial splenic cysts are a rare entity and they can be an incidental finding during the surgical treatment of a spleen rupture and haemoperitoneum. These cysts may be a predisposing factor to splenic rupture in cases of increased intraabdominal pressure or blunt abdominal trauma.

Introduction: With recent advancements in the field of minimally invasive surgery, combined laparoscopic procedure is now being performed for treating coexisting abdominal pathologies during the same surgery. In some patients, spleen disorders are associated with gallbladder stones. Conventional surgery requires a wide upper abdominal incision for correct exposure of both organs. The aim of this study was to assess the feasibility and outcomes of concomitant laparoscopic treatment for coexisting spleen and gallbladder diseases., Materials and Methods: Thirty consecutive laparoscopic splenectomy (LS) plus laparoscopic cholecystectomy (LC) have been performed in our department between January 2000 and December 2009 (24% of 125 LS performed in this period). There were 11 female patients and 19 male patients, with a median age of 16.2 years (range: 4-55). Indications were hereditary spherocytosis for 22 cases, idiopathic thrombocytopenic purpura for 3 cases, thalassemia for 4 cases, and sickle cell disease for 1 case. Patients were operated on using right semilateral position, tilting the table from right to left, using a five-trocar technique in 25 cases and a four-trocar technique in the last 5 cases. Cholecystectomy was performed first, then splenectomy was achieved, and spleen was removed in an Endobag., Results: One patient required conversion to open procedure (3.3%) because of splenomegaly. Average operative time was 150 minutes (range: 90-240). Average length of stay was 3.5 days (range: 3-11). Mean blood loss was 60  mL (range: 30-500). Transfusion rate was 3.3%. Mean spleen size and weight were, respectively, 16.5  cm and 410  g. No perioperative mortality occurred in the series. We reported 3 cases of hemoperitoneum, of which one managed conservatively. The results using four trocars were comparable to those with five trocars., Conclusion: With increasing institutional experience, concomitant laparoscopic splenectomy and cholecystectomy is a safe and feasible procedure and may be considered for coexisting spleen and gallbladder diseases. The four-trocar technique guarantees good results.

Splenectomy indications and outcome were evaluated in 124 adults with hemoglobin SC disease (Hb SC). Twelve patients (9.6%) required splenectomy. There was a significant difference between the splenectomy group and the non-splenectomy group, respectively, regarding Hb levels (median 7.2 g/dL vs. 12.5 g/dL, P < 0.0001), platelet counts (median 146 x 10(6)/L vs. 275 x 10(6)/L, P = 0.031), palpable spleen rate (66% vs. 16%, P = 0.0003%), acute chest syndrome frequency (75% vs. 12%P = 0.0004) and cholecystectomy rate (66% vs. 13%, P = 0.0004). No significant morbidity or mortality occurred postsplenectomy. There is a subgroup of Hb SC patients requiring splenectomy, in which splenectomy is effective. Although it appears to be safe regarding short-term complications of surgery, long-term adverse effects such as infections have to be evaluated cautiously.

Gastropleural fistula is a rare condition that occurs as a consequence of various thoraco-abdominal surgical procedures and septic conditions. The diagnosis is difficult, it needs a high index of suspicion and appropriate investigations. There are no previous reports of a patient developing a fistula after a splenectomy procedure. The authors report a twelve-year old boy who developed gastropleural fistula following thoracoabdominal surgery, a splenectomy. The patient presented with the clinical condition of chronic empyema thoracis and responded well to medical and surgical treatment.

Background: Sepsis is a feared complication in patients with an absent or dysfunctioning spleen., Methods: A literature search was undertaken to identify recommendations for vaccination in asplenic or hyposplenic adults, and published data regarding the effectiveness of the vaccines in reducing the incidence of infections, and vaccine failures., Results: Various committees and organizations recommend that the pneumococcal, meningococcal and Haemophilus influenza vaccine, plus booster doses, should be administered to patients with an absent or dysfunctional spleen. However, adherence to such recommendations varies. Furthermore, vaccine failures still occur in a subset of properly immunized individuals. Immunocompromised individuals, in particular, have a greater risk of inadequate antibody response., Conclusion: Immunization is partially responsible for the observed reduction in sepsis after splenectomy., (2008 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.)

Background: Despite extensive work-up to establish the cause of splenomegaly, splenectomy may be required for diagnosis in certain situations. The aim of this study was to find out the role of diagnostic splenectomy in the current era., Methods: Between January 1989 and June 2004, 211 patients underwent splenectomy for indications other than trauma. In 41 (19%) patients, splenectomy was carried out for diagnostic purposes. Retrospective analysis of these patients was done for the purpose of the study., Results: All patients who underwent diagnostic splenectomy had a complete haemogram, biochemical tests for liver and renal function, bone marrow biopsy and abdominal ultrasonography before splenectomy. There were 28 (68%) men and 13 (32%) women with median age of 37 years (range, 6-62 years). The median duration of symptoms was 12 months (range, 1-180 months). Common presentations were fever (n = 27; 66%), malaise (n = 26; 63%), pallor (n = 33; 80%) and gross splenomegaly (n = 27; 66%). Thirty-two (78%) patients had hypersplenism. Splenic lesions were shown in 14 (34%) patients on ultrasonogram and in 16 (39%) patients on contrast-enhanced computed tomography scan of the abdomen. Open splenectomy was carried out in all patients. Seventeen (41%) patients had postoperative complications. Among these, three (7%) patients had postoperative bleeding. One patient died because of acute respiratory distress syndrome. Final histopathology of the spleen showed lymphoma in 15 (37%), tuberculosis in five (12%) and other lesions in five (12%) patients. Sixteen (39%) patients had only congestive splenomegaly., Conclusion: A high proportion of patients presenting with idiopathic splenomegaly will have underlying haematological malignancies even in tropical countries. The clinical presentation, laboratory profile and imaging findings were not helpful in differentiating between patients with haematological malignancies and non-malignant conditions. Splenectomy still has an important role in establishing the pathology in patients presenting with idiopathic splenomegaly.

The wandering spleen is caused by congenital absence of fixating ligaments or abnormally long ligaments. It is an uncommon clinical entity, which rarely affects children. The clinical presentation of wandering spleen is variable, but the most dangerous complication is splenic torsion. A 7 year-old boy presented with abdominal pain and vomiting. The abdominal ultrasound scan discovered spleen ischemia. Volvulus of the spleen was evoked. Laparotomy was carried out and the patient underwent splenectomy. In this case the anatomical means of spleen fixity were absent. Because wandering spleen is uncommon in the paediatric population, a heightened awareness of the condition is required for accurate diagnosis and appropriate management. The treatment of choice is splenopexy, while if splenic necrosis is present, splenectomy is required.

Conditions that once were considered either relative or absolute contraindications for laparoscopic splenectomy have become fewer and less significant in the overall assessment of candidates for this procedure. Advances in surgical technique, operative conduct, and instrumentation have made it feasible to perform splenectomy laparoscopically with good outcomes and minimal morbidity in a variety of different pathologic conditions. Obesity, malignancy, pregnancy, and splenomegaly are assessed here in detail.

We present the case of a 33-year-old man with isolated splenic peliosis, a rare pathological condition characterized by blood filled cystic lesions. The patient presented with recurrent massive haemorrhagic ascites, which did not resolve, despite a splenectomy. He was found to have massively elevated levels of vascular endothelial growth factor (VEGF). The clinical course of the disease was prolonged. Repeated blood transfusions for recurrent anaemia were required, in addition to repeated aspiration of reaccumulating haemorrhagic ascites and pleural effusion. The clinical course was not in keeping with previously reported cases. We have described an atypical clinical presentation in a patient with isolated splenic peliosis associated with elevated VEGF concentrations. No previously known associations for the condition were found despite thorough investigations. Management of the patient has been symptomatic and palliative. We have reviewed the various reported associations of peliosis and discussed the possible role of VEGF in this patient's condition.

Background: Hand-assisted laparoscopic surgery (HALS) devices may be well suited to splenectomy in cases of splenomegaly., Methods: All cases of HALS for splenectomy between 1997 and 2001 were reviewed. Patient characteristics, operative details, and morbidity and mortality were analyzed., Results: HALS for splenectomy was performed in 54 patients. A total of 39 patients with massive splenomegaly (MS) (>600 g) were identified. The average weight of the MS group was 1285 +/- 505 g. There was one (3%) conversion. Operative time was 159 +/- 65 min, estimated blood loss was 257 +/- 240 ml, and length of hospital stay was 5.4 +/- 2.9 days. Morbidity was limited to 13 patients (24%), and there were two postoperative mortalities (5.1%)., Conclusions: HALS for splenectomy in the setting of splenomegaly is feasible and safe. For the surgeon considering a laparoscopic approach in the setting of splenomegaly, a hand-assisted technique is ideally suited for removal of the enlarged spleen.

The aim of the present work was to summarise in a single paper all the options for prevention of life-threatening infections due to encapsulated bacteria in patients with hyposplenism or asplenia. Prevention of these infections should be obtained in all patients with 1) patient and family education, 2) prophylaxis by means of vaccination against Haemophilus influenzae and Streptococcus pneumoniae, 3) antibiotic prophylaxis, based primarily on penicillin, 4) delay of elective splenectomy or use methods of tissue salvage in splenic trauma. Vaccination is not effective against all serotypes of S. pneumoniae and Neisseria meningitidis causing life-threatening infections in hypo/asplenic patients. Moreover, antibacterial prophylaxis could select antibacterial-resistant pathogens and is highly conditioned by patient's compliance. Therefore, empirical antibacterial therapy of fever and/or suspected infection should be recommended to all splenectomised patients independently from time elapsing from splenectomy, vaccinal status and assumption of antibacterial prophylaxis.

FROM ASPLENIA TO SEVERE INFECTION: The most serious consequence of asplenia due to absence of the spleen, its resection or its functional failure is the risk of severe infection. RAPIDLY PROGRESSIVE SEPTICEMIA: It is estimated that the risk of death due to septicemia is 200 times higher in splectomized patients than in patients with a spleen. Death occurs within several days or even hours in most of the patients due to overwhelming post-splenectomy infection (OPSI). The bacteria causing OPSI are predominantly pneumococci (50-80% of identified infections) as well as meningococci, Haemophilus sp, and other capsulated bacteria. IMPORTANCE OF AGE: The risk of infection is even greater if asplenia began early in life, either because of rapidly progressive congenital hemotological disease or splenectomy during infancy or early childhood. According to Holdsworth, infectious morbidity in subjects splenectomized before the age of 16 years is 4.4%, mortality reaches 2.2%. In adults, morbidity is 0.9% and mortality 0.8%. PREVENTION OF RECURRENCE: Furthermore, in an asplenic subject or in a patient with a chronic disease threatening the spleen, the development of infectious episodes is an expression of evolving immunodepression, calling for preventive measures against recurrence. Anti-pneumococcal vaccination and antibiotic prophylaxis using penicillin V considerably reduces the incidence of pneumococcal infection in splenectomized subjects.

Splenic abscess is a rare clinical entity that is most commonly associated with infective endocarditis. Valve replacement in the setting of an unaddressed splenic abscess is associated with a high incidence of prosthetic valve infection and death. We describe 2 patients with infective endocarditis and splenic abscess treated by laparoscopic splenectomy followed by valve replacement.

Guidelines for the prevention and treatment of infection in patients with an absent or dysfunctional spleen were first published by the British Committee for Standards in Haematology in 1996. Key aspects of these guidelines related to anti-infective prophylaxis, immunisation schedules and treatment of proven or suspected infection. A recent review of the guidelines was undertaken, with a view to updating the recommendations where necessary The guideline review process did not reveal any major change in patient groups considered at risk. Occupational exposure to certain pathogens may, however, be a new risk factor for some infections. The recommendations for anti-infective prophylaxis remain unchanged. New recommendations for vaccination include the use of meningococcal group C vaccine in previously non-immunised hyposplenic patients and a need to consider the use of seven-valent pneumococcal vaccine. Recommendations for treatment of suspected or proven infection have not been significantly amended, but a local protocol should take into account relevant resistance patterns. There is an identified urgent need for further research into the effectiveness of varying vaccination strategies in the hyposplenic patient, and audit of infective episodes in this patient group should continue long term. Key guidelines are summarised below, together with grades of recommendation.

Portal vein aneurysm is a rare medical entity that can be caused by chronic hepatic diseases with portal hypertension. We describe a 45-year-old man with variceal bleeding from hepatosplenic schistosomiasis and an incidentally found intrahepatic aneurysm. Diagnosis was confirmed with non-invasive imaging exams, arteriography and liver biopsy. Following splenectomy, the aneurysm diameter decreased substantially.

We report a rare case of isolated thrombocytopenia due to a large hamartoma of the pulposal type, which resolved with splenectomy in a 46-year-old man. Although hamartomas are usually found incidentally, they may cause hematologic disturbances such as thrombocytopenia, anemia, or splenic rupture. The diagnosis of splenic hamartoma is difficult to make preoperatively. Splenectomy is important in excluding malignant tumors from the diagnosis when the etiology of a splenic mass is unclear and ameliorating hematologic symptoms related to hamartomas.

Background: Laparoscopic splenectomy (LS) is now regarded as the treatment of choice for autoimmune thrombopenia (ITP). However, there have been few reports describing the application of LS to other splenic diseases, such as malignant entities and conditions associated with splenomegaly. Hematological diseases have specific clinical features that can influence immediate outcome after LS. Although the long-term effects of LS are unknown, a risk of splenosis has been suggested. Therefore, we designed a study to analyze the impact of primary hematological disease on immediate and late outcome in a prospective series of LS patients., Methods: We performed a prospective analysis of 111 LS done between February 1993 and March 1999. The patients were classified by hematological indications into the following four groups: (a) group 1, low platelet count. This group was further subdivided into group 1A, idiopathic thrombocytopenic purpura (ITP) (n = 48) and group 1B, HIV-related ITP (n = 8); (b) group 2, anemia. This group was further subdivided into group 2A, autoimmune hemolytic anemia (n = 8), and group 2B, spherocytosis (n = 11); (c) group 3, malignancy (n = 28); and (d) group 4, others (n = 8). Immediate outcomes were recorded prospectively. Hematological status and late complications were reviewed after a mean follow-up of 24 +/- 18 months., Results: There were no significant differences between the groups in terms of conversion, transfusion requirements, and morbidity, although transfusion and morbidity were slightly higher in group 3. However, hospital stay was significantly longer in groups 3 and 4 than in groups 1 and 2. Long-term follow-up showed satisfactory hematological results in >/=75% of patients (group 1A, 82%; group 1B, 88%; group 2A, 88%; group 2B, 100%; group 3, 75%; group 4, 88%). Overall, late morbidity was 8.3% and mortality was 6.2%, mainly due to deaths in group 4 (six of 22 patients)., Conclusion: LS is a safe and reproducible procedure for most hematological indications, with a similar immediate outcome for benign diseases and a long-term hematological response comparable to the standard results that have been observed in open series.

Background: Splenic complications of sickle-cell disease (SCD) are associated with morbidity, and in some it may lead to mortality. This paper presents our experience with 43 patients with SCD who had splenectomy as part of their management., Patients and Methods: The records of 43 patients with SCD who had splenectomy were examined for age at operation, sex, hemoglobin (Hb) electrophoresis, indication for splenectomy, pre- and postoperative medications, operative procedures, and postoperative complications., Results: The indications for splenectomy were acute splenic sequestration crisis (ASSC) in 21 patients, hypersplenism in 15, and splenic abscess in 7. In 17 patients, the spleen was also found to be massively enlarged causing discomfort and intervening with everyday activity. For those with hypersplenism, there was a significant postoperative increase in total Hb (P < 0.0001), hematocrit (P < 0.0001), white blood cells (P < 0.0001), and platelet count (P < 0.0001)., Conclusions: With careful perioperative management and proper follow-up, splenectomy in patients with SCD is beneficial in reducing their transfusion requirements and its attendant risks, eliminating the discomfort from mechanical pressure of the enlarged spleen, avoiding the risks of ASSC, and managing splenic abscess.

Fifty dogs undergoing splenectomy for splenic masses (n = 40), torsion of the splenic pedicle (n = 5), and immune-mediated disease (n = 5) were evaluated preoperatively and and postoperatively for ventricular arrhythmias and the relationship between ventricular arrhythmia splenic disease. The ability of 1-minute electrocardiograms recorded every 6 hours (ECGs/q6hr) to detect ventricular arrhythmia was compared with continuous 48-hour Holter monitoring. Based on continuous Holter monitoring, splenectomized dogs had a high incidence (22 of 50) of rapid ventricular tachycardia. The incidence of rapid ventricular tachycardia was significantly higher in dogs with ruptured splenic masses (16 of 23) than without rupture (1 of 17) (P < .001). When the results of ECG/q6hr were compared with the results of continuous Holter monitoring ECG/q6hr was normal in 29% (4 of 14) of dogs with rapid ventricular tachycardia at > 3,000 ventricular extrasystoles (VE)/hr; 50% (4 of 8) of dogs with rapid ventricular tachycardia at 1,000 to 3,000 VE/hr and 100% (6 of 6) of dogs with 10 to 300 VE/hr without rapid ventricular tachycardia. Although dogs undergoing splenectomy had a high incidence of ventricular arrhythmias, one-minute ECGs/q6h were unreliable for detection of ventricular arrhythmias even when high-frequency extrasystoles occurred.

Within a 17-month period, 130 orthotopic liver transplantations were performed in our hospital. Nine of these were retransplantations and were not included in our analysis. In the remaining 121 patients, splenectomy was performed in 34 patients, either synchronously with the transplant procedure (27 patients) or in the postoperative period (7 patients). Indications for splenectomy were lienalis-steal syndrome in 15 patients and hypersplenism in 15 cases. The number of rejection episodes was fairly equal in both groups (splenectomized vs. non-splenectomized, 61.7% vs. 63.9%, respectively). There was a marked difference in the frequency of infectious episodes (61.7% vs. 25.3%) that resulted in a decreased survival rate (77.5% vs. 95.4%) for splenectomized patients. Therefore, we recommend splenectomy only for very selected patients and investigate the banding of the splenic artery as an alternative.
