Abstract
A 72-year-old man received chemoradiotherapy for lung squamous cell carcinoma(T4N2M0, Stage Ⅲb). Nine months after the start of chemoradiotherapy, a 60 mm sized mass was identified in the spleen on abdominal CT. FDG-PET/CT examination revealed abnormal FDG accumulation in the tumor, and no obvious accumulation was observed in other sites. By endoscopic ultrasound-guided fine needle aspiration cytology, the tumor was diagnosed as splenic metastasis from lung cancer. Since the primary lung tumor was well controlled by the chemoradiotherapy and no metastatic lesions were found except in the spleen, laparoscopic excision of the splenic metastasis was planned. Since the tumor was suspected to have infiltrated the tail of the pancreas, laparoscopic distal pancreatectomy and splenectomy were performed. There were no severe postoperative complications. The resected tumor was histopathologically diagnosed as not splenic metastasis, but lymph node metastasis at the splenic hilum from lung cancer invading the pancreas and spleen. Brain metastasis and bone metastasis were observed 3 months postoperatively. He did not undergo any treatments for the metastatic lesions, and he died because of the cancer 11 months after the operation. This case suggests the clinical significance of surgical treatment for distant metastatic lesions from lung cancer.

Abstract
BACKGROUND Initial results of Washington State's quality improvement initiative addressing the management of blunt traumatic pediatric spleen injuries were published in 2008. In this update, we evaluated whether these effects were sustained over time. METHODS Data from the Washington Trauma Registry for years 1999-2001 (pre-intervention), 2003-2005 (post-intervention), and 2012-2014 (follow-up) were used in a retrospective cohort study. Children between ages 0 to 14 years who were hospitalized with a traumatic blunt spleen injury were included. Multivariable logistic regression was used to account for patient, injury, and hospital characteristics. RESULTS Overall, splenectomies continued to be less common with 8.3% of pediatric patients receiving splenectomies in the follow-up period compared with 14.3% and 7.2% in the preintervention and post-intervention periods (p = 0.034). After adjustment, splenectomies remained less likely to be performed in both post-intervention (OR = 0.37; 95% CI = 0.16-0.90) and follow-up periods (OR = 0.29; 95% CI = 0.12-0.70) compared to pre-intervention. Children were much more likely to be cared for at pediatric trauma hospitals in the follow-up period (OR = 5.13; 95% CI = 2.79-9.43) after adjustment. CONCLUSIONS Evaluation of this statewide quality improvement initiative showed that positive changes in management practices persist. This evidence suggests that statewide quality improvement initiatives can be sustainable with minimal ongoing effort. LEVEL OF EVIDENCE Level III.

Abstract
INTRODUCTION The majority of patients with splenic trauma undergo non-operative management (NOM); around 15% of these cases fail NOM and require surgery. The aim of the current study is to assess whether the hemodynamic status of the patient represents a risk factor for failure of NOM (fNOM) and if this may be considered a relevant factor in the decision-making process, especially in Centers where AE (angioembolization), intensive monitoring and 24-h-operating room are not available. Furthermore, the presence of additional risk factors for fNOM was investigated. MATERIALS AND METHODS This is a multicentre prospective observational study, including patients presenting with blunt splenic trauma older than 17 years, managed between 2014 and 2016 in two Italian trauma centres (ASST Papa Giovanni XXIII in Bergamo and Sant'Anna University Hospital in Ferrara-Italy). The risk factors for fNOM were analyzed with univariate and multivariate analyses. RESULTS In total, 124 patients were included in the study. In univariate analysis, the risk factors for fNOM were AAST grade > 3 (fNOM 37.5% vs 9.1%, p = 0.024), and the need of red blood cell (RBC) transfusion in the emergency department (ED) (fNOM 42.9% vs 8.9%, p = 0.011). Multivariate analysis showed that the only significant risk factor for fNOM was the need for RBC transfusion in the ED (p = 0.049). CONCLUSIONS The current study confirms the contraindication to NOM in case of hemodynamically instability in case of splenic trauma, as indicated by the most recent guidelines; attention should be paid to patients with transient hemodynamic stability, including patients who require transfusion of RBC in the ED. These patients could benefit from AE; in centers where AE, intensive monitoring and an 24-h-operating room are not available, this particular subgroup of patients should probably be treated with operative management.

Abstract
INTRODUCTION Gastric volvulus is a rare cause of acute abdomen in childhood, and it is usually a casual finding. We present the case of a girl with mesenteroaxial gastric volvulus, which was initially treated by endoscopic approach. CLINICAL CASE 8 year-old patient, diagnosed of Down syndrome, who presented sudden and diffuse colic pain, associated with vomiting, sialorrhea and progressive compromise. She entered in bad general condition. At the physical examination it was highlighted a large abdominal mass. In the imaging study, a mesenteroaxial gastric volvulus and wandering spleen were confirmed. It was decided to perform an endoscopic gastric devolvulation under general anesthesia. Subsequently, gastropexy and splenopexy were performed by laparotomic approach. Evolution was uneventful, being discharged at the tenth postoperative day. COMMENTS Endoscopic gastric devolvulation is an effective procedure in patients with gastric volvulus, especially in cases of great compromise of the general state, in which a prolonged surgery could suppose a greater risk.

Abstract
Innate lymphoid cells (ILCs) have been characterized as innate immune cells capable to modulate the immune response in the mucosae. Human ILCs have been rarely described in secondary lymphoid organs except in tonsils. Moreover, their function and phenotype in human secondary lymphoid organs during autoimmune diseases have never been studied. We took advantage of splenectomy as a treatment of immune thrombocytopenia (ITP) to describe and compare splenic ILC from 18 ITP patients to 11 controls. We first confirmed that ILC3 represented the most abundant ILC subset in human non-inflamed spleens, accounting for 90% of total ILC, and that they were mostly constituted of NKp44- cells. On the contrary, proportions of ILC1 and ILC2 in spleens were lower than in blood. Splenic IL-2- and IFN-γ-producing ILC1 were increased in ITP. While the frequencies of total splenic ILC3 were similar in the two groups, splenic GM-CSF-producing ILC3 were increased in ITP. This is the first description of human ILC in a major secondary lymphoid organ during an autoimmune disease, ITP. We observed an expansion of splenic ILC1 that could participate to the Th1 skewing, while the increased production of GM-CSF by splenic ILC3 could stimulate splenic macrophages which play a key role in ITP pathophysiology.

Abstract
Metabolism is a critical basis for immune cell functionality. It was recently shown that NK cell subsets from peripheral blood modulate their expression of nutrient receptors following cytokine stimulation, demonstrating that NK cells can adjust to changes in metabolic requirements. As nutrient availability in blood and tissues can significantly differ, we examined NK cells isolated from paired blood-liver and blood-spleen samples and compared expression of the nutrient transporters Glut1, CD98 and CD71. CD56bright tissue-resident (CXCR6+) NK cells derived from livers and spleens expressed lower levels of Glut1 but higher levels of the amino acid transporter CD98 following stimulation than CD56bright NK cells from peripheral blood. In line with that, CD56dim NK cells, which constitute the main NK cell population in the peripheral blood, expressed higher levels of Glut1 and lower levels of CD98 and CD71 compared to liver CD56bright NK cells. Our results show that NK cells from peripheral blood differ from liver- and spleen-resident NK cells in the expression profile of nutrient transporters, consistent with a cell-adaptation to the different nutritional environment in these compartments.

Abstract
A 70-year-old woman with hepatitis C cirrhosis underwent balloon-occluded retrograde transvenous obliteration for hepatic encephalopathy due to spleno-renal shunt. Because the shunt was thick, long, and winding, we used a coaxial and double interruption system, which enables the effective occlusion of the drainage route, and shape-memory coils, which are more physically stable than conventional metallic coils because they form three-dimensional loops. The patient was successfully treated with the combined usage of these devices, resulting in a normal serum ammonia level. Thereafter, the patient was treated with direct-acting antivirals, and a sustained virological response was achieved.

Abstract
RATIONALE Sclerosing angiomatoid nodular transformation (SANT) is a rare case which usually occurs in spleen, but our case occurs in accessory spleen. PATIENT CONCERNS We reported a case of a 27 year old man who was identified with an isodense mass in the left abdominal cavity by ultrasonicphysical examination without symptoms. Blood routine and tumor markers (alpha fetal protein, carcinoembryonic antigen, CA19-9, CA125) were normal. DIAGNOSES The tumor was firstly diagnosed as left abdominal mass and its origin was considered as small intestinal by the radiologist. The pathological diagnosis was the sclerosing angiomatoid nodular transformation (SANT) of the accessory spleen. INTERVENTIONS Laparoscopic splenectomy is a more reliable method for the treatment of SANT. OUTCOMES Non-enhanced CT showed iso-intensity lesion of the accessory spleen, and enhanced CT showed progressive enhancement. According to the above characteristics, we should consider the diagnosis of spleen SANT. We reviewed some literatures to summarize the characteristics of SANT.

Abstract
RATIONALE Melioidosis is an emerging infectious disease caused by Burkholderia pseudomallei. To our knowledge, there have been very few cases of splenic abscesses due to melioidosis in Hainan, China. PATIENT CONCERNS The patient was a 55-year-old male farmer, who was admitted in our hospital with persistent left epigastric dull pain accompanied by chills and febrile. One month before, the patient presented with persistent abdominal pain. After received anti-infection therapy, the subjective symptoms eased slightly, but recently he suffered from intermittent abdominal pain again. DIAGNOSES Bacteria isolated from splenic pus were identified as B. pseudomallei by the Phoenix-100 system and indirect immunofluorescence. INTERVENTIONS The patient was treated by surgical excision and anti-infection therapy. OUTCOMES The patient was then treated with intravenous ceftazidime and oral trimethoprim-sulfamethoxazole for 2 weeks and his clinical symptoms improved. LESSONS In endemic areas, B. pseudomallei should be considered as a causative organism of splenic abscess in patients with established risk factors. The isolation of B. pseudomallei from abscess sites is crucial to improve clinical outcomes by appropriate antimicrobial therapy coupled with surgical drainage.

Abstract
To evaluate variation in care nationwide for children with splenic injuries at pediatric trauma, adult trauma, and nontrauma centers. We used the National Inpatient Sample from 2001 to 2010 to identify pediatric patients with splenic injury. We analyzed demographic, clinical, and hospital status characteristics. The primary objective was comparison of splenectomy rates at pediatric, adult, and nontrauma centers. We identified 34,599 patients with splenic injury. Throughout the study, 3,979 (11.5%) patients underwent splenectomy: 8.2 per cent of patients at pediatric trauma, 17.6 per cent at adult trauma, and 14.5 per cent at nontrauma centers. Multivariate regression analysis demonstrated patients had decreased odds of splenectomy at pediatric trauma centers compared with adult and nontrauma centers (OR = 0.42, P < 0.001). In addition, children aged 14 to 17 years (OR = 2.5) with injury severity score > 14 (OR = 5.8) had increased odds of undergoing splenectomy. In this nationwide sample, children with splenic injury treated at adult trauma and nontrauma centers had significantly higher rates of splenectomy compared with children treated at pediatric trauma centers. We highlight the need for interventions that ensure all injured children receive appropriate and high quality trauma care.

Abstract
Accessory spleen (AS) is common anomaly, and 20% of AS cases occur in the pancreatic tail. An intrapancreatic AS can be difficult to distinguish from pancreatic neoplasms. In most cases, an AS is described as a hypervascular and solitary tumor, but an AS sometimes takes other forms. We herein report a rare case of an intrapancreatic AS with temporal changes in its appearance after splenectomy, which mimicked aspects of pancreatic cancer. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) and 99mTc sulfur colloid scintigraphy were useful for the diagnosis.

Abstract
UNLABELLED there are not a sufficient number investigating the factors in splenic injuries influencing mortality. In this study, we aimed to investigate the factors affecting mortality in splenic injuries. MATERIALS AND METHODS All 237 patients with splenic injury between 2005 to 2014 were retrospectively analyzed. The patients were divided into two groups, survivors and non-survivors. Age, gender, mechanism of injury, grade of splenic injury, pulse, respiratory rate, systolic blood pressure, hemoglobin levels, number of transfusions, surgical procedure, ISS, RTS and hospitalization period were recorded. Univariate and multivariate analysis were used to compare survivors and non-survivors. RESULTS The average age of the patients was 32 and most (82.7%) were male. Mortality was observed in 18 patients (7.6%). Mortality was found significantly lower in patients who had isolated splenic injury (p=0.048). In univariate analyses, decreased RTS (p<0.001), increased number of blood transfusion (p<0.001), decreased hemoglobin level (p=0, 025) and increased ISS (p<0.001) were found significant in non-survivors. In multivariate analysis; number of transfusions, ISS and RTS were found as independent risk factors for mortality. CONCLUSIONS We found high number of transfusions, high ISS and low RTS as independent risk factors for mortality in patients with splenic injury. KEY WORDS Mortality, ISS, RTS, Splenic trauma.

Abstract
OBJECTIVE The meta-analysis was performed to investigate the clinical efficacy of spleen-preserving distal pancreatectomy with splenic vessel preservation (SPDP-SVP) and spleen-preserving distal pancreatectomy with splenic vessel resection (SPDP-SVR). METHODS Potential articles were searched on the databases of Pubmed, Embase, and Chinese National Knowledge Infrastructure (CNKI) from January 1988 until March 2017. Weight mean difference (WMD) with 95% confidence interval (CI) was applied to compare the efficacy of SPDP-SVP and SPDP-SVR. Odds ratio (OR) with 95% CI was calculated to figure out the risks for complications. P< .05 or I>50% indicated significant heterogeneity. The random-effects model is used to pool data if significant heterogeneity exists; otherwise, the fixed-effects model is used. Publication bias was evaluated by Begg's funnel plot. RESULTS Thirteen eligible articles were obtained in the meta-analysis. SPDP-SVP seemed to relate with reduced operative time and blood loss, prolonged hospital stay, and less complications; however, the effects were not statistically significant. Meanwhile, we found that SPDP-SVP was closely related with the reduced rate of splenic infarction and gastric varices (OR = 0.16, 95% CI = 0.09-0.29; OR = 0.08, 95% CI = 0.02-0.35). No publication bias was observed in the analysis (P = .636). CONCLUSIONS SPDP-SVP seems to show superiority than SPDP-SVR in reducing the rate of splenic infarction and gastric varices.

Abstract
Although the spleen is the most commonly injured intra-abdominal organ after blunt trauma, there are limited data available in China. The objectives of this study were to investigate the clinical features and determine the risk factors for operative management (OM) in children with blunt splenic injury (BSI).A review of the medical records of children diagnosed with BSI between January 2010 and September 2016 at West China Hospital of Sichuan University was performed.A total of 101 patients diagnosed with BSI were recruited, including 76 patients transferred from other hospitals. The male-to-female ratio was 2.06:1, with a mean age of 7.8 years old. The most common injury season was summer and the most common injury mechanism was road traffic accidents. Sixty-eight patients suffered multiple injuries. Thirty-four patients received blood transfusions. Two patients died from multiple organ failure or hemorrhagic shock. Significant differences were observed in the injury season, injury mechanism, injury date, and hemoglobin levels between the isolated injury group and the multiple injuries group. The overall operative rate was 29.7%. Multivariate regression analysis revealed that age, blood transfusion, and grade of injury were independent risk factors for OM.Our study provided evidence that the management of pediatric BSI was variable. The operative rate in pediatric BSI may be higher in certain patient groups. Although nonoperative management is one of the standard treatment options, our data suggest that OM is an appropriate way to treat patients who are hemodynamically unstable.

Abstract
An 81-year-oldwoman with advancedgastric cancer was referredto our hospital. Preoperative contrast-enhancedCT revealeda roundcalcification of the splenic hilum with 15mm in diameter as a splenic artery aneurysm. She underwent transcatheter arterial embolization(TAE)for the splenic artery aneurysm. Celiac artery angiography showedcollateral arterial network of the spleen from left gastric artery. Surgery for the gastric cancer was performed1 4 days after TAE. We cut the right gastric andbilateral epigastric arteries. After the left gastric artery clamping, we performedintraoperative indocyanine green(ICG)fluorography. ICG fluorography confirmedthat the bloodflow of the upper thirdof the stomach andspleen were maintained. We safely performed distal gastrectomy, and the postoperative course was uneventful.

AIMS/HYPOTHESIS Beta cell replacement is a potential cure for type 1 diabetes. In humans, islet transplants are currently infused into the liver via the portal vein, although this site has disadvantages. Here, we investigated alternative transplantation sites for human and murine islets in recipient mice, comparing the portal vein with quadriceps muscle and kidney, liver and spleen capsules. METHODS Murine islets were isolated from C57BL6/J mice and transplanted into syngeneic recipients. Human islets were isolated and transplanted into either severe combined immunodeficiency (SCID) or recombination-activating gene 1 (RAG-1) immunodeficient recipient mice. All recipient mice were 8-12 weeks of age and had been rendered diabetic (defined as blood glucose concentrations ≥20 mmol/l on two consecutive days before transplantation) by alloxan tetrahydrate treatment. Islets were transplanted into five different sites (portal vein, quadriceps muscle, kidney, liver and spleen capsules). Blood glucose concentrations were monitored twice weekly until mice were killed. Dose-response studies were also performed to determine the minimum number of islets required to cure diabetes ('cure' is defined for this study as random fed blood glucose of <15 mmol/l). RESULTS For transplantation of murine islets into the different sites, the kidney yielded 100% success, followed by muscle (70%), portal vein (60%), spleen capsule (29%) and liver capsule (0%). For human islets, transplantation into the kidney cured diabetes in 75-80% of recipient mice. Transplantation into muscle and portal vein had intermediate success (both 29% at 2000 islet equivalents), while transplantation into liver and spleen capsule failed (0%). With increased islet mass, success rates for muscle grafts improved to 52-56%. CONCLUSIONS/INTERPRETATION For both human and murine islets, equivalent or superior glucose lowering results were obtained for transplantation into skeletal muscle, compared with the portal vein. Unfortunately, kidney grafts are not feasible in human recipients. Skeletal muscle offers easier access and greater potential for protocol biopsies. This study suggests that human trials of muscle as a transplant site may be warranted.

Abstract
AIMS/HYPOTHESIS Xenotransplantation has great potential to provide beta cell replacement and thereby provide a cure for large numbers of people with type 1 diabetes. Crucial to the success of xenotransplantation is establishment of the most viable sites for transplantation. METHODS We compared porcine islet tissue transplanted into kidney, liver and spleen in pig recipients as assessed by blood glucose levels and IVGTT. RESULTS Kidney was the superior site for porcine islet tissue transplantation, followed by liver then spleen. This was demonstrated by IVGTTs showing significant difference between the peak glucose levels: 22.8 ± 2.9 mmol/l for kidney compared with 26.8 ± 1.3 mmol/l for spleen and 24.7 ± 1.7 mmol/l for liver. CONCLUSIONS/INTERPRETATION Kidney grafts are not as feasible in humans and liver results were relatively poorer than spleen. For islet transplantation to be viable and successful in the longer term, there remains a need for future investigation of alternative sites.

Abstract
AIM To provide the overall spectrum of gastrosplenic fistula (GSF) occurring in lymphomas through a systematic review including a patient at our hospital.
METHODS A comprehensive literature search was performed in the MEDLINE database to identify studies of GSF occurring in lymphomas. A computerized search of our institutional database was also performed. In all cases, we analyzed the clinicopathologic/radiologic features, treatment and outcome of GSF occurring in lymphomas.
RESULTS A literature search identified 25 relevant studies with 26 patients. Our institutional data search added 1 patient. Systematic review of the total 27 cases revealed that GSF occurred mainly in diffuse, large B-cell lymphoma (n = 23), but also in diffuse, histiocytic lymphoma (n = 1), Hodgkin’s lymphoma (n = 2), and NK/T-cell lymphoma (n = 1, our patient). The common clinical presentations are constitutional symptoms (n = 20) and abdominal pain (n = 17), although acute gastrointestinal bleeding (n = 6) and infection symptoms due to splenic abscess (n = 3) are also noted. In all patients, computed tomography scanning was very helpful for diagnosing GSF and for evaluating the lymphoma extent. GSF could occur either post-chemotherapy (n = 10) or spontaneously (n = 17). Surgical resection has been the most common treatment. Once patients have recovered from the acute illness status after undergoing surgery, their long-term outcome has been favorable.
CONCLUSION This systematic review provides an overview of GSF occurring in lymphomas, and will be helpful in making physicians aware of this rare disease entity.

Recent trends in 30-day mortality in patients with blunt splenic injury: A nationwide trauma database study in Japan. PLoS One 2017; 12:e0184690. [PMID: 28910356 PMCID: PMC5599007 DOI: 10.1371/journal.pone.0184690] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2017] [Accepted: 08/29/2017] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Splenic injury frequently occurs after blunt abdominal trauma; however, limited epidemiological data regarding mortality are available. We aimed to investigate mortality rate trends after blunt splenic injury in Japan. METHODS We retrospectively identified 1,721 adults with blunt splenic injury (American Association for the Surgery of Trauma splenic injury scale grades III-V) from the 2004-2014 Japan Trauma Data Bank. We grouped the records of these patients into 3 time phases: phase I (2004-2008), phase II (2009-2012), and phase III (2013-2014). Over the 3 phases, we analysed 30-day mortality rates and investigated their association with the prevalence of certain initial interventions (Mantel-Haenszel trend test). We further performed multiple imputation and multivariable analyses for comparing the characteristics and outcomes of patients who underwent TAE or splenectomy/splenorrhaphy, adjusting for known potential confounders and for within-hospital clustering using generalised estimating equation. RESULTS Over time, there was a significant decrease in 30-day mortality after splenic injury (p < 0.01). Logistic regression analysis revealed that mortality significantly decreased over time (from phase I to phase II, odds ratio: 0.39, 95% confidence interval: 0.22-0.67; from phase I to phase III, odds ratio: 0.34, 95% confidence interval: 0.19-0.62) for the overall cohort. While the 30-day mortality for splenectomy/splenorrhaphy diminished significantly over time (p = 0.01), there were no significant differences regarding mortality for non-operative management, with or without transcatheter arterial embolisation (p = 0.43, p = 0.29, respectively). CONCLUSIONS In Japan, in-hospital 30-day mortality rates decreased significantly after splenic injury between 2004 and 2014, even after adjustment for within-hospital clustering and other factors independently associated with mortality. Over time, mortality rates decreased significantly after splenectomy/splenorrhaphy, but not after non-operative management. This information is useful for clinicians when making decisions about treatments for patients with blunt splenic injury.

Abstract
OBJECTIVE To explore the value of criminal fold priority separating (CFPS) in reduction of iatrogenic splenic injury in laparoscopic radical gastrectomy. METHODS Complete videos of 270 patients undergoing laparoscopic radical gastrectomy in Guangdong Provincial Hospital of Chinese Medicine were reviewed. Anatomic features of criminal fold (CF) were summarized. The relationship between CFPS and iatrogenic splenic injury was examined. CF was defined as the ligament between omentum and spleen. CFPS was defined as that CF was separated before the left half gastrocolic omentum was dissected. Splenic injury was further compared between CFPS group and non-CFPS group. RESULTS CF occurred in 81.5% cases (220/270), presenting one bunch or multiple bunches. CF appeared most commonly in the lower pole of spleen (76.7%, 207/270), then in middle spleen (14.1%, 38/270) and upper pole (9.6%, 26/270). CFPS was performed in 20% cases (54/270) and 80% cases (216/270) were non-CFPS. The incidence of iatrogenic splenic injury was 11.1% (30/270), and this incidence of CFPS group was lower as compared to non-CFPS group (3.7%, 2/54 vs. 13.0%, 28/216), but the difference was not significant (P=0.07). Of 30 patients with splenic injury, 24(80%) were due to traction of CF and all were in non-CFPS group. Instrument injury occurred in 20% cases(6/30) and 2 were in CFPS group and 4 were in non-CFPS group. Most iatrogenic splenic injuries were successfully handled with electrocoagulation, adhesive and compression, except 2 patients underwent open splenectomy for serious splenic injury in non-CFPS group. CONCLUSION In laparoscopic surgery for gastric cancer, iatrogenic splenic injury mostly results from improper traction of CF and CFPS can reduce the incidence of iatrogenic splenic injury.

Abstract
RATIONALE Splenosis is the development of one or more heterotopic splenic tissue autoimplants following rupture of the spleen and remains mostly asymptomatic. PATIENT CONCERNS We report a case of a 50-year old post-traumatic splenectomized man admitted for a left side community acquired pneumonia resistant to antibiotics. DIAGNOSES The diagnosis of intrathoracic ectopic spleen was suspected because of the history of spleen trauma with diaphragm rupture and the absence of Howell-Jolly bodies. INTERVENTIONS Technetium (Tc)-m colloid scintigraphy SPECT, fused with CT scan showed an intense radionuclide uptake on hyper vascularized masses without any additional pathologic uptake and confirmed the diagnosis of thoracic splenosis. OUTCOMES Despite any lifelong penicillin prophylaxis, he had no history of infections eight years after the diagnosis. LESSONS Physician must be aware of this differential diagnosis and of its consequences. Depending on its size and location, it may lead to incorrect diagnosis (tumor, empyema, abscess ...), treatment and invasive procedures while the diagnosis of splenosis only relies upon imaging studies associated with functionnal study of the uptake of particles or cells.

Abstract
Transplanted hepatocytes integrate, survive, and express their specific functions in the liver parenchyma. The aim of this study was to determine whether a large number of hepatocytes could move from the spleen to the liver when the cells are injected together with sodium nitroprusside, and if the improved hepatocyte migration may be related with portal vein dilatation. Wistar rats were transplanted in the spleen with fluorescent-labeled hepatocytes alone or together with sodium nitroprusside. At 1, 3, 6, and 24 h after the transplant, the liver from recipient animals was removed and morphometric analyses were performed. Portal and arterial pressures were also measured immediately after intrasplenic injection of a solution of sodium nitroprusside, hepatocytes alone, or hepatocytes plus sodium nitroprusside. Intrasplenically injected sodium nitroprusside produced a transient drop in arterial pressure and a sustained reduction in portal pressure. During hepatocyte transplantation it increased the number of transplanted cells migrating to the liver after 3 h. Sodium nitroprusside simultaneously injected with hepatocytes in the spleen allowed more cells to migrate into the liver of the host animal without risk in animal survival.

Abstract
BACKGROUND Pancreatic resection for cancer represents a real challenge for every surgeon. Recent improvements in laparoscopic experience, minimally invasive surgical techniques and instruments make now the minimally invasive approach a real "triumph." There is no doubt that minimally invasive surgery has replaced with great success conventional surgery in many fields, including surgical oncology. METHODS AND RESULTS However, its progress in pancreatic resection for adenocarcinoma has been dramatically slow. Recent evidence supports the notion that minimally invasive distal pancreatectomy is safe and feasible and that is becoming the procedure of choice mainly for benign or low-grade malignant lesions in the distal pancreas. On the other side, minimally invasive pancreatoduodenectomy has not yet been widely accepted and there is enormous skepticism when applied for pancreatic head adenocarcinoma. In this review, we summarize the current evidence on the potential applications of minimally invasive surgical approaches for this aggressive, heterogeneous, and enigmatic type of cancer. CONCLUSIONS Moreover, the potential future applications of these approaches are discussed with the hope to improve the quality of life as well as the survival rates of pancreatic cancer patients.
