An unusual case of primary splenic soft part alveolar sarcoma: case report and review of the literature with emphasis on the spectrum of TFE3-associated neoplasms. Diagn Pathol 2024; 19:62. [PMID: 38643139 PMCID: PMC11031972 DOI: 10.1186/s13000-024-01483-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Accepted: 04/02/2024] [Indexed: 04/22/2024] Open
Abstract
BACKGROUND Alveolar soft part sarcoma is a rare tumour of soft tissues, mostly localized in muscles or deep soft tissues of the extremities. In rare occasions, this tumour develops in deep tissues of the abdomen or pelvis. CASE PRESENTATION In this case report, we described the case of a 46 year old man who developed a primary splenic alveolar soft part sarcoma. The tumour displayed typical morphological alveolar aspect, as well as immunohistochemical profile notably TFE3 nuclear staining. Detection of ASPSCR1 Exon 7::TFE3 Exon 6 fusion transcript in molecular biology and TFE3 rearrangement in FISH confirmed the diagnosis. CONCLUSION We described the first case of primary splenic alveolar soft part sarcoma, which questions once again the cell of origin of this rare tumour.

Treatment of a contained rupture of a splenic artery pseudoaneurysm with direct thrombin injection. J Vasc Surg Cases Innov Tech 2024; 10:101398. [PMID: 38304297 PMCID: PMC10830532 DOI: 10.1016/j.jvscit.2023.101398] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Accepted: 11/17/2023] [Indexed: 02/03/2024] Open
Abstract
Splenic artery pseudoaneurysm is a rare and potentially fatal condition. In the present report, we describe the case of a 50-year-old woman with chronic pancreatitis who presented with worsening abdominal pain. Computed tomography demonstrated a 3.5-cm splenic artery pseudoaneurysm of the mid-splenic artery. The patient underwent attempted endovascular repair of the pseudoaneurysm that was unsuccessful. Open conversion revealed an inaccessible splenic artery due to chronic pancreatitis that resulted in dense retroperitoneal fibrosis, and repair was achieved via direct thrombin injection under ultrasound guidance of the pseudoaneurysm and splenectomy. The patient recovered well, and computed tomography at 3 days postoperatively revealed complete thrombosis of the pseudoaneurysm.

The amphibian's spleen as a source of biomarkers for ecotoxicity assessment: Historical review and trends. THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 901:165915. [PMID: 37532037 DOI: 10.1016/j.scitotenv.2023.165915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 07/27/2023] [Accepted: 07/28/2023] [Indexed: 08/04/2023]
Abstract
Amphibians are very sensitive to many environmental changes, so these animals are considered good bioindicator models for ecotoxicology. Given the importance of the amphibian spleen for hematopoietic and immune responses, this can be a key organ for the evaluation of biomarkers to monitor the health of individuals in nature or in captivity. In this systematic review, we searched databases and summarized the main findings concerning the amphibian spleen as a source of possible biomarkers applied in different scientific fields. The searches resulted in 83 articles published from 1923 to 2022, which applied the use of splenic samples to evaluate the effects of distinct stressors on amphibians. Articles were distributed in more than twenty countries, with USA, Europe, and Brazil, standing out among them. Publications focused mainly on anatomical and histomorphological characterization of the spleen, its physiology, and development. Recently, the use of splenic biomarkers in pathology and ecotoxicology began to grow but many gaps still need to be addressed in herpetological research. About 85 % of the splenic biomarkers showed responses to various stressors, which indicates that the spleen can provide numerous biomarkers to be used in many study fields. The limited amount of information on morphological description and splenic anatomy in amphibians may be a contributing factor to the underestimated use of splenic biomarkers in herpetological research around the world. We hope that this unprecedented review can instigate researchers to refine herpetological experimentation, using the spleen as a versatile and alternative source for biomarkers in ecotoxicology.

Splenic infarction secondary to polycythemia Vera: Case report and literature review. Radiol Case Rep 2023; 18:3636-3641. [PMID: 37593336 PMCID: PMC10432139 DOI: 10.1016/j.radcr.2023.07.049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Revised: 07/19/2023] [Accepted: 07/21/2023] [Indexed: 08/19/2023] Open
Abstract
Splenic infarction is a medical condition characterized by compromised blood flow to the spleen, resulting in partial or complete organ infarction. This condition is commonly observed in patients with an increased risk of thrombosis, such as those with Polycythemia Vera (PV). A 40-year-old female patient presented with fatigue, weakness, and an enlarged spleen, further tests revealed elevated levels of hemoglobin, white blood cells, and platelets. A bone marrow biopsy and positive Jack II mutations confirmed the diagnosis of PV. The patient later developed portal hypertension, varices, and splenic infarction. This case report aims to raise awareness about the potential complications of PV and emphasizes the importance of early intervention to prevent serious consequences such as splenic infarction. Additionally, it highlights the role of splenectomy in managing complications associated with PV.

Abstract
In areas where tuberculosis is prevalent, a splenic tuberculosis should be considered in the differential diagnosis of patients presenting with fever of unknown origin and splenomegaly. The diagnosis can be made later when complications occur as well as spontaneous rupture of the spleen. Although rare, chest rupture can occur and symptoms can be respiratory as well as pyopneumothorax or empyema, which can lead to inaccurate diagnosis and inappropriate treatment of the an underlying condition.

Abstract
A 56-year-old female with thrombocythemia complicated by portal venous system thrombosis presented with recurrent left pleural effusions after failed recanalization via mechanical thrombectomy and stenting at an outside center. With no other cause, splenic vein thrombosis and left-sided portal hypertension was suggested as a possible etiology. Partial splenic embolization was performed with immediate decrease in effusions and resolution by 8 weeks. Portal and splenic venous system thrombosis may cause recurrent pleural effusions from left-sided portal hypertension and fluid leakage across diaphragmatic defects. Upper pole partial splenic embolization may treat recurrent left pleural effusions and offer an alternative to splenectomy.

Evaluation of cross-sectional imaging features that aid in the differentiation of benign and malignant splenic lesions. Eur J Radiol 2021; 136:109549. [PMID: 33465552 DOI: 10.1016/j.ejrad.2021.109549] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2020] [Revised: 01/09/2021] [Accepted: 01/12/2021] [Indexed: 12/21/2022]
Abstract
PURPOSE This study aimed to investigate the role of cross-sectional imaging in differentiating between benign and malignant splenic lesions based on various imaging features. METHODS Database of imaging reports from January 2015 to December 2017 were searched dedicatedly for "spleen" or "splenic" terms to identify patients with splenic lesions found either on CT or MRI. The study cohort consisted of patients who had available histological reports or had follow-up imaging for a minimum of one year. Patients were categorized into the benign subcohort if they did not have a history of extra-splenic malignancy, and had a splenic lesion(s) falling into one of these categories: benign histopathology on biopsy, stable size and enhancement, or decreased size on follow-up imaging. Those who had malignant histopathology on biopsy were included in the malignant subcohort. Various morphologic features and enhancement patterns of these lesions were carefully reviewed by two radiologists who were blinded to the final histopathologic diagnosis. RESULTS We identified 161 patients (54 % males, mean age ± SD = 59.7 ± 15.4) including 124 (77 %) in the benign and 37 (23 %) in the malignant subcohort. Benign lesions were more likely to be cystic (21.7 % vs 2.7 %, p < 0.001), homogenous (59.7 % vs. 29.7 %, p = 0.001) and to demonstrate well-defined borders (69.3 % vs. 29.7 % p= <0.001). Malignant lesions had significantly larger diameter (median size: 15 vs 11 mm, p = 0.03). Restricted diffusion was not seen in any of the benign lesions; however, 50 % of malignant lesions demonstrated restricted diffusion (p = 0.003). Features such as lesion distribution, presence of calcification, splenomegaly and number of lesions were not significantly different between benign and malignant lesions. CONCLUSION Smaller lesion diameter, well-defined border and homogeneity favor benign nature of splenic lesions while restricted diffusion should raise suspicion for malignancy.

Predictors of surgical management of high grade blunt splenic injuries in adult trauma patients: a 5-year retrospective cohort study from an academic level I trauma center. Patient Saf Surg 2020; 14:32. [PMID: 32774457 PMCID: PMC7398213 DOI: 10.1186/s13037-020-00257-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Accepted: 07/21/2020] [Indexed: 12/13/2022] Open
Abstract
Backgrounds Splenic injury accounts for 40% of all injuries after blunt abdominal trauma. Blunt splenic injury in hemodynamically unstable patients is preferably treated by splenectomy. Nowadays hemodynamically stable patients with low grade splenic injuries are mostly treated by non-operative management (NOM). However no consensus exists about the management of high grade splenic injuries in hemodynamically stable patients. Therefore the aim of this study was to analyze patients with high grade splenic injuries in our institution. Methods We retrospectively included all patients with a splenic injury presented to our level I trauma center during the 5-year period from January 1, 2012, until December 31, 2017. Baseline characteristics, data regarding complications and mortality were collected from the electronic patient registry. Patients were grouped based on splenic injury and the treatment they received. Results A total of 123 patients were included, of which 93 (75.6%) were male with a median age of 31 (24–52) and a median injury severity score of 27 (17–34). High grade injuries (n = 28) consisted of 20 Grade IV injuries and 8 grade V injuries. Splenectomy was required in 15/28 (53.6%) patients, of whom all remained hemodynamically unstable after resuscitation, including all grade V injuries. A total of 13 patients with high grade injuries were treated with spleen preserving therapy. Seven of these patients received angio-embolization. One patient went for laparotomy and the spleen was treated with a hemostatic agent. Secondary hemorrhage was present in 3 of these patients (initial treatment: 1 embolization/ 2 observational), resulting in a success rate of 76.9%. There is no mortality seen in patient with high grade splenic injuries. Conclusion Non-operative treatment in high grade splenic injuries is a safe treatment modality in hemodynamically stable patients. Hemodynamic status and peroperative bleeding, not injury severity or splenic injury grade were the drivers for surgical management by splenectomy. This selected cohort of patients must be closely monitored to prevent adverse outcomes from secondary delayed bleeding in case of non-operative management.

Endovascular flow-diversion of visceral and renal artery aneurysms using dual-layer braided nitinol carotid stents. CVIR Endovasc 2020; 3:33. [PMID: 32596773 PMCID: PMC7321844 DOI: 10.1186/s42155-020-00125-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Accepted: 05/13/2020] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND Visceral and renal artery aneurysms (VRAAs) are uncommon but are associated with a high mortality rate in the event of rupture. Endovascular treatment is now first line in many centres, but preservation of arterial flow may be difficult in unfavourable anatomy including wide necked aneurysms, parent artery tortuosity and proximity to arterial bifurcations. Endovascular stenting, and in particular flow-diversion, is used in neurovascular intervention to treat intracranial aneurysms but is less often utilised in the treatment of VRAAs. The CASPER stent is a low profile dual-layer braided nitinol stent designed for carotid stenting with embolic protection and flow-diversion properties. We report the novel use of the CASPER stent for the treatment of VRAAs. We present a case series describing the treatment of six patients with VRAAs using the CASPER stent. RESULTS Six patients with unruptured VRAAs were treated electively. There were three splenic artery aneurysms and three renalartery aneurysms. Aneurysms were treated with the CASPER stent, with or without loose aneurysm coil packing or liquid embolic depending on size and morphology. All stents were successfully deployed with no immediate or periprocedural complications. Four aneurysms completely occluded after serial imaging follow up with one case requiring repeat CASPER stenting for complete occlusion. In one patient a single aneurysm remained patent at last follow up, A single case was complicated by delated splenic infarction and surgical splenectomy. CONCLUSION Preliminary experience with the CASPER stent suggests it is technically feasible and effective for use in the treatment of VRAAs.

Abstract
Primary malignant fibrous histiocytoma, now classified as pleomorphic undifferentiated sarcoma, is the most common soft-tissue sarcoma in adult life. Primary splenic pleomorphic undifferentiated sarcoma is extremely rare and aggressive, and is associated with a poor prognosis; only 14 cases of splenic pleomorphic undifferentiated sarcoma have been documented in the English literature. We discuss a case of a 56-year-old woman with iron-deficiency anaemia, early satiety and left upper-quadrant pain, who was preoperatively diagnosed with a large splenic cyst following thorough investigation. This was excised in an elective procedure. Unfortunately, histology confirmed splenic pleomorphic undifferentiated sarcoma. Following a review and summary of the literature, we discuss key differentials between splenic cysts and splenic pleomorphic undifferentiated sarcoma. This case highlights that iron-deficiency anaemia is unusual in splenic cysts and more sinister causes must be considered.

Abstract
BACKGROUND True giant splenic artery aneurysms (GSAAs) >5 cm are rare and present unique therapeutic challenges. The aim of this study was to evaluate the anatomic and clinical characteristics of these lesions and the current surgical and endovascular techniques available for their treatment. METHODS A systematic review of the literature from 2004 to 2018 and the personal experience of the authors with management of GSAAs are presented. A total of 92 GSAA cases were reviewed. Analyses were performed on anatomic and clinical features and management modalities and outcomes of GSAA, including reintervention, morbidity, and mortality. RESULTS GSAA presented at a mean age of 56.1 ± 17.3 years, with no sex predilection; 73% were symptomatic at presentation. Abdominal pain was the presenting symptom in >50% of cases; 34% percent were ruptured, with an overall mortality rate of 12.5%. This group often presented with gastrointestinal bleeding or hemodynamic collapse. The aneurysms were almost evenly distributed across the splenic artery and were not uncommonly associated with arteriovenous fistula formation (8.7%). There were 88 patients who had surgical (53.4%), endovascular (44.3%), or combination (2.3%) therapy. The most commonly performed procedure was aneurysmectomy and splenectomy with or without additional resection. Overall, surgical treatment had a lower morbidity (P = .041) than endovascular therapy and comparable reintervention and mortality rates. CONCLUSIONS GSAAs are uncommon vascular lesions, with distinct clinical features and aneurysm characteristics. Considering their high risk of rupture, timely diagnosis and management are essential to attain a satisfactory outcome. Surgery remains the standard treatment of these lesions. Endovascular intervention is a viable alternative in high-risk patients, particularly those with lesions <10 cm or with anomalous origin.

Abstract
BACKGROUND Cancer of cervix often fails locally and/or within the pelvis. One to two percent of cervical squamous cell carcinoma patients have lung metastases at presentation, and 5-35% develop pulmonary metastases later on. Common sites of metastases are the liver, bone, and bowel. We report a rare case presentation of cervical squamous cell cancer where heterochronous metastasis occurred in the skin, spleen, and pancreas without loco-regional recurrence and skipping of visceral organs such as the lung, liver, and brain. CASE PRESENTATION A 55-year-old, postmenopausal lady presented with a complaint of bleeding of the vagina for 2 months duration. Cervical biopsy revealed squamous cell carcinoma of the cervix, and she was staged as a case of FIGO stage IIIB. She received external beam-beam radiotherapy of 50 Gy in 25 fractions along with concurrent weekly cisplatin at 35 mg/m2 followed by 3 fractions of intracavitary brachytherapy of 6 Gy each. After 30 months of follow-up, she presented with a skin lesion of 6 × 5 cm2 in the infrascapular region for 2 months duration. Biopsy revealed metastatic squamous cell carcinoma. Her metastatic work-up revealed no other lesions. Palliative radiotherapy to local site of 8 Gy in single fraction was delivered. The lesion disappeared within 4 weeks. She was given 6 cycles of cisplatin and paclitaxel salvage chemotherapy. After 30 months of follow-up, she presented with a skin lesion of 6 × 5 cm2 in the infrascapular region. Biopsy revealed metastatic squamous cell carcinoma. Her metastatic work-up revealed no other lesions. Palliative radiotherapy to the local site was planned, and a dose of 8 Gy in a single fraction was delivered. The lesion disappeared within 4 weeks. She was given 6 cycles of cisplatin and paclitaxel salvage chemotherapy. Six months after the completion of salvage therapy, she reported with the complaints of recurrent bouts of hematemesis and melena. Her CECT scan revealed 2 × 1.5 cm2 growth in the body of the pancreas and a subcentric splenic hilum node. She underwent open splenectomy with distal pancreatectomy. Histopathology report showed metastatic infiltration in pancreatic tissue by squamous cell carcinoma and one metastatic node in the splenic hilum. Post-treatment, 6 months, the patient was asymptomatic with no recurrence. CONCLUSIONS This is a rare heterochronous metastatic presentation of cervical cancer without loco-regional recurrence and visceral organs such as the lung, liver, and brain. The optimal treatment remains undefined for these patients. Multimodality treatment is necessary to manage the patients.

Abstract
Portomesenteric vein thrombosis is a rare but potentially fatal complication of bariatric surgery. Portomesenteric venous thrombosis complicated 3 of 1030 cases (0.29%). Management is primarily with anticoagulants, but surgery is required if the patient shows signs of sepsis. A high index of suspicion, early diagnosis and subsequent adequate management is required.
Introduction Portomesenteric vein thrombosis is a rare but documented complication of laparoscopic surgery. This rare complication is currently being encountered more frequently with the increase in the rates of laparoscopic bariatric surgery procedures being performed worldwide. Methods A retrospective analysis was performed on all bariatric procedures performed in our center between July 2012 & December 2017 to identify cases complicated by portomesenteric venous thrombosis. The cases were compared in terms of operative details, patient presentation, diagnosis, patient risk factors for developing thrombosis, demographics and thrombophilia analysis & subsequent treatment and prognosis. Results A total of 1030 bariatric procedures were performed between July 2012 & December 2017. Portomesenteric venous thrombosis complicated 3 of these cases (0.29%). Two of these cases had underwent a laparoscopic sleeve gastrectomy while the third had underwent a gastric band removal and a conversion to a single anastomosis gastric bypass. Amongst these patients, 2 were female while 1 was male with an average BMI 38.9 kg/m2. Only one of these patients was a smoker while none of them tested positive for thrombophilias. The diagnosis of portomesenteric venous thrombosis was confirmed with a contrast CT of the abdomen as all patients were re-admitted between 4–20 days post operatively after being discharged on postoperative day 2. All three cases were managed with systemic anticoagulants and none underwent invasive procedures or were re-explored surgically. All were subsequently discharged in good condition. Conclusion Portomesenteric venous thrombosis is an uncommon yet potentially fatal complication of bariatric surgery. A high index of suspicion, early diagnosis and subsequent adequate management is required. Based on this case series and the potential risk of portomesenteric venous thrombosis, we altered our clinical practice to include a 1 week course of low molecular weight heparin to be administered to all patients after discharge.

Abstract
Introduction Splenic rupture after laparoscopic surgery is a very rare complication. In this study, we report a case of a splenic laceration that occurred during a laparoscopic gastrostomy tube placement. The theorized mechanism in this case was acute disruption of a peri-splenic hematoma. Case report A 64-year-old African-American male presented after a motor vehicle accident with multiple injuries and was admitted to a surgical intensive care unit, where he declined from ICU days 6 through 11. The patient underwent tracheostomy and laparoscopic gastrostomy tube placement given his significant neurologic deficits. Intraoperatively, the patient developed hypotension, leading to the discovery of hemoperitoneum and necessitating an emergent open splenectomy. Conclusion Splenic rupture following laparoscopic procedures is a very rare phenomenon. In this case, we believe the splenic rupture was secondary to an acute disruption of a previously hemostatic splenic hematoma involving the abdominal wall during creation of capnoperitoneum.

Abstract
Primary splenic angiosarcoma carries a poor prognosis and is among the rarest forms of malignancy. An overwhelming majority of patients with splenic angiosarcoma will develop metastases. However, osseous metastatic disease is rare. We present an 83 year old hispanic female who was diagnosed with primary splenic angiosarcoma on bone marrow biopsy performed for a hematologic workup. We highlight key historical, laboratory, imaging, and pathological features of splenic angiosarcoma. The synthesis of both imaging features and clinical history is essential for establishing early diagnosis in these patients.

Abstract
PURPOSE To review the management of children and adolescents (0-18 years), with blunt splenic injury treated at a single UK major trauma centre over a 5-year period, focusing upon efficacy of non-operative management and the use of haemodynamic stability as a guide to planning treatment strategy, rather than radiological injury grading. To produce a treatment pathway for management of blunt splenic injury in children. METHODS Retrospective, cross-sectional study of all paediatric patients admitted with radiologically proven blunt splenic injury between January 2011 and March 2016. Penetrating injuries were excluded. Follow up was for at least 30 days. RESULTS 30 Patients were included, mean age was 14.5 (SD 3.6), median injury severity score was 16 (IQR 10-31). 6 Patients (20%) had a splenectomy, whilst 22 patients (73%) were successfully treated non-operatively with 100% efficacy at index admission. 5/8 (63%) patients with radiological grade V injuries were managed non-operatively, injury grade was not associated with surgical intervention (p = 1.57). Haemodynamic instability was initially treated with fluid resuscitation leading to successful non-operative management in 5/11 (45%) patients. However, haemodynamic instability is a significant predictor of requirement for surgical intervention (p = 0.03), admission to critical care (p = 0.017), presence of additional injuries (p = 0.015) and increased length of stay (p = 0.038). No such relationships were found to be associated with increased radiological injury grade. CONCLUSIONS Non-operative management should be first-line treatment in the haemodynamically stable child with a blunt splenic injury and may be carried out with a high degree of efficacy. It may also be successfully implemented in those initially showing signs of haemodynamic instability that respond to fluid resuscitation. Radiological injury grade does not predict definitive management, level of care, or length of stay; however, haemodynamic stability may be utilised to produce a treatment algorithm and is key to guiding management.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is gaining popularity for the treatment of morbid obesity. It is a simple, low-cost procedure resulting in significant weight loss within a short period of time. LSG is a safe procedure with a low complication rate. The most significant complications are staple-line bleeding, stricture, and staple-line leak. Formation of liver and splenic abscesses is an extremely rare consequence of LSG. Liver abscess has been reported in one case report while splenic abscess has been reported in five case reports after LSG. METHODS This study is a case report and literature review. RESULTS We report two cases of a pyogenic liver abscesses and two cases of splenic abscesses after LSG. CONCLUSIONS As LSG becomes more popular, clinicians need to be aware of uncommon but potentially serious complications related to it.

Abstract
Serpiginoid multifocal choroiditis is a distinct morphological identity with a reported causal association with Mycobacterium tuberculosis. We report a case of serpiginoid multifocal choroiditis in a 17-year-old boy who was suffering from isolated splenic tuberculosis. He was treated with systemic steroids along with anti-tubercular treatment with good visual recovery. This case was unique as no other organs except spleen and choroid showed tubercular involvement. We hereby emphasize association of extrapulmonary sites with multifocal serpiginoid choroiditis and propose a thorough investigation for primary to be included in routine protocol of choroiditis workup.

Management of blunt splenic injury in a UK major trauma centre and predicting the failure of non-operative management: a retrospective, cross-sectional study. Eur J Trauma Emerg Surg 2017; 44:397-406. [PMID: 28600670 DOI: 10.1007/s00068-017-0807-5] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2017] [Accepted: 05/29/2017] [Indexed: 10/19/2022]
Abstract
PURPOSE To review the management of patients >16 years with blunt splenic injury in a single, UK, major trauma centre and identify whether the following are associated with success or failure of non-operative management with selective use of arterial embolization (NOM ± AE): age, Injury Severity Score (ISS), head injury, haemodynamic instability, massive transfusion, radiological hard signs [contrast extravasation or pseudoaneurysm on the initial computed tomography (CT) scan], grade, and presence of intraparenchymal haematoma or splenic laceration. METHODS Retrospective, cross-sectional study undertaken between April 2012 and October 2015. Paediatric patients, penetrating splenic trauma, and iatrogenic injuries were excluded. Follow-up was for at least 30 days. RESULTS 154 patients were included. Median age was 38 years, 77.3% were male, and median ISS was 22. 14/87 (16.1%) patients re-bled following NOM in a median of 2.3 days (IQR 0.8-3.6 days). 8/28 (28.6%) patients re-bled following AE in a median of 2.0 days (IQR 1.3-3.7 days). Grade III-V injuries are a significant predictor of the failure of NOM ± AE (OR 15.6, 95% CI 3.1-78.9, p = 0.001). No grade I injuries and only 3.3% grade II injuries re-bled following NOM ± AE. Age ≥55 years, ISS, radiological hard signs, and haemodynamic instability are not significant predictors of the failure of NOM ± AE, but an intraparenchymal or subcapsular haematoma increases the likelihood of failure 11-fold (OR 10.9, 95% CI 2.2-55.1, p = 0.004). CONCLUSIONS Higher grade injuries (III-V) and intraparenchymal or subcapsular haematomas are associated with a higher failure rate of NOM ± AE and should be managed more aggressively. Grade I and II injuries can be discharged after 24 h with appropriate advice.

Abstract
B-cell non-Hodgkin lymphomas with plasmacytic differentiation are a diverse group of entities with extremely variable morphologic features. Diagnostic challenges can arise in differentiating lymphoplasmacytic lymphoma from marginal zone lymphoma and other low-grade B-cell lymphomas. In addition, plasmablastic lymphomas can be difficult to distinguish from diffuse large B-cell lymphoma or other high-grade lymphomas. Judicious use of immunohistochemical studies and molecular testing can assist in appropriate classification.

Abstract
INTRODUCTION Although uncommon, the incidence of splenic injury from colonoscopy has been increasing significantly since first being reported in 1974. Early recognition is critical because mortality may be as high as 5%. METHODS We systematically searched PubMed and EMBASE to identify English-language cases of splenic injury from colonoscopy from inception until January 26, 2015. We used descriptive statistics to characterize the identified cases. RESULTS A total of 172 cases from 122 reports were included. The mean age was 64 years and 70.8% were females. Prior abdominal or pelvic surgeries were identified in 63.8%. 57.3% of patients underwent polypectomies or biopsies. There was a statistically significant increase in use of computerized tomography for diagnosis in the past 5 years (81.8% versus 65.2%). 76.1% patients received transfusions. Mean inpatient length of stay was 7.83 ± 5.32 days. A non-significant trend toward conservative management was noted in the past 5 years (37.7% versus 23.1%), and a non-significant drop in mortality was noted (4.9% versus 5.4%). DISCUSSION Our data support prior literature suggesting a higher incidence of splenic injuries during colonoscopies in females, advanced age, prior history of abdominal/pelvic surgeries and biopsies/polypectomies during the procedure. CONCLUSIONS Significant mortality associated with splenic injuries during colonoscopies warrants prompt recognition of this potentially life threatening, albeit uncommon, complication.

Abstract
BACKGROUND Thrombotic events involving the portal-splenic-mesenteric venous system (PSMVT) are rare but potentially lethal after bariatric surgery. OBJECTIVES To investigate the incidence, clinical presentation, management, and outcome of thrombotic events after bariatric surgery. SETTING Two university hospitals. METHODS A retrospective review of individuals who underwent bariatric surgery between January 2006 and December 2015. RESULTS Overall, 4386 patients underwent bariatric surgery (laparoscopic sleeve gastrectomy [LSG; n = 2886], laparoscopic Roux-en-Y gastric bypass [n = 762], laparoscopic adjustable gastric banding [n = 668], and biliopancreatic diversion [n = 70]). Mechanical (thigh-length pneumatic compression stockings) and pharmacologic thromboprophylaxis (40 mg enoxaparin daily, starting 12 hours after surgery until discharge) was provided for all patients. A minority of patients (n = 543, 12.4%) also received an extended course of enoxaparin for 1-4 weeks after discharge. We observed 16 cases of PSMVT, all after LSG, with an incidence of .55% (16/2886). Twelve additional patients experienced deep vein thrombosis and 6 had pulmonary embolism. Follow-up imaging indicated complete resolution in all cases, with no sequelae, recurrent thrombosis, or mortality. The overall thrombosis rate was significantly lower in patients who received an extended course of anticoagulation after LSG (P = .01) and after any type of bariatric surgery (P = .02). CONCLUSIONS PSMVT was found to occur uncommonly after LSG. Prompt diagnosis and anticoagulation therapy led to favorable outcomes in most cases. Significantly lower rates of thrombosis were found in patients who received an extended course of anticoagulation. We support its use for at least 1 week after discharge.

Abstract
Spleen is an unusual location for hydatid cyst. Here we report a case of primary splenic hydatid cyst in a 41-yr-old Iranian woman from Yasuj, southwest of Iran. The patient had been admitted to Shahid Beheshti Hospital because of abdominal pain. Abdominal sonography revealed a hypoechoic lesion of 150 X 130 mm in the spleen, suggestive of hydatid cyst. Splenectomy was performed for the patient and surgical interventions revealed a hydatid cyst occupying most of splenic parenchyma. She was discharged on the 5 day of her operation. Postoperative diagnosis and confirmation of hydatid cyst was done by histopathological, molecular and serological approaches. Histopathological evaluation revealed the classical laminated layer of hydatid cyst. DNA was extracted from a part of cyst and PCR amplified. Sequencing and analysis of PCR product revealed that the isolate has the most similarity with G1 strain of Echinococcus granulosus. Patient's serum was positive for IgG anti-hydatid cyst antibodies, using antigen-B ELISA.

Abstract
Splenic Artery Syndrome (SAS) has emerged as a controversial cause for graft ischemia in orthotopic liver transplant (OLTx) recipients. A complex combination of factors including hepatic artery hypoperfusion and portal hyperperfusion can result in SAS. Clinical and laboratory findings suggest graft ischemia but are generally non-specific. Conventional angiography findings of hepatic artery hypoperfusion with early and rapid filling of the splenic artery are suggestive of the diagnosis in the appropriate clinical setting. Treatment involves proximal splenic artery embolization, surgical splenic artery ligation, or in extreme cases, splenectomy. Most patients with SAS improve clinically following treatment. However, no randomized control trials are available to compare treatment options. Identification of at risk patients with pre-operative CT scans and intra-operative ultrasound has been proposed by some and may allow for prophylactic treatment of SAS.

Abstract
Splenic hamartoma (SH) is a rare benign tumor usually detected accidentally, which is composed of an aberrant mixture of normal splenic elements. Here, we report a case of 54-year-old man who presented with symptomatic multinodular SH and was admitted initially for thrombocytopenia and anemia. Physical examination revealed that the patients had an anemic appearance and palpable spleen, extending 10 cm below the costal margin. Preoperative ultrasound and computed tomography (CT) indicated splenomegaly with multinodular lesions. On enhanced CT scanning, during the arterial phase, the lesions demonstrated inhomogeneous enhancement, and in the portal phase the lesions were more hyperdense than the splenic parenchyma. The images were highly suggestive of a metastatic tumor. Splenectomy was performed 1 wk later. The tumor was eventually diagnosed as SH according to the morphological features and immunohistochemical detection, by which CD34 was positive in lining cells and some spindle cells, vimentin was positive in the tumor, factor-VIII-related antigen was positive multifocally in lining cells, and smooth muscle actin was positive in some spindle cells. Thrombocytopenia and anemia were cured after splenectomy.

Abstract
Hydatid cyst disease, which is endemically observed and an important health problem in our country, involves the spleen at a frequency ranking third following the liver and the lungs. In this study, we aimed to evaluate the efficacy and results of management in splenic hydatid cysts. The demographic data, localization, diagnosis, treatment methods, and the length of postoperative hospital stay of patients with splenic hydatid cysts in a 12-year period were evaluated retrospectively. Seventeen cases were evaluated. Among these, 13 were females and four were males. Seven had solitary splenic involvement, eight had involvement of both the spleen and the liver, and two had multiple organ involvement. Ten had undergone splenectomy, one had undergone distal splenectomy, and the remaining cases had undergone different surgical procedures. The patients had received albendazole treatment in the pre- and postoperative period. One patient had died secondary to hypernatremia on the first postoperative day. The clinical picture in splenic hydatid cysts, which is seen rarely, is usually asymptomatic. The diagnosis is established by ultrasonography and abdominal CT. Although splenectomy is the standard mode of treatment, spleen-preserving methods may be used.

Abstract
Visceral Leishmaniasis or Kala Azar is endemic in certain regions of India. In endemic areas, the constellation of fever, progressive weight loss, weakness, pronounced splenomegaly, anemia, leukopenia, and hypergammaglobulinemia is highly suggestive of visceral leishmaniasis. Demonstration of the parasite in liver, splenic or bone marrow aspirates is confirmatory. We present a case in which Leishmania donovani (LD) bodies were demonstrated on splenic aspirate. We were unable to demonstrate LD bodies on bone marrow aspiration.
