RESUMO

INTRODUCTION: Splenic injury is common in blunt trauma. We sought to evaluate the injury characteristics and outcomes of BSI admitted over a 10-y period to an academic trauma center. METHODS: A retrospective review of adult blunt splenic injury patients admitted between January 2009 and September 2018. RESULTS: The 423 patients meeting inclusion criteria were divided by management: Observational (OBS, n = 261), splenic surgery (n = 114 including 4 splenorrhaphy patients), SAE (n = 43), and multiple treatment modalities (3 had SAE followed by surgery and 2 OBS patients underwent splenic surgery at readmission). The most common mechanism of injury was motor vehicle collision (47.8%). The median ISS (OBS 17, SAE 22, Surgery 34) and spleen AIS (OBS 2, SAE 3, Surgery 4) were significantly different.  Complication rates (OBS 21.8%, SAE 9.3%, Surgery 45.6%) rates were significantly different, but mortality (OBS 7.3%, SAE 2.3%, Surgery 13.2%), discharge to home and readmission rates were not. Additional abdominal injuries were identified in 26.3% of the surgery group and 2.7% of OBS group. SAE rate increased from 3.0% to 28%; median spleen AIS remained 2-3. Thirty-five patients expired; 28 had severe head, chest, and/or extremity injuries (AIS ≥4). CONCLUSION: SAE rates increased over time. Splenorrhaphy rates were low. SAE was associated with relatively low rates of mortality and complications in appropriately selected patients.

RESUMO

INTRODUCTION: The aim of this study was to study radiological assessment, management and outcome of traumatic splenic injury over 15 years in a UK district general hospital. METHOD: A retrospective database was established including all splenic injury cases from June 2002 to June 2017 by searching the clinical electronic database. We searched the radiological database for computed tomography reported phrases 'spleen injury', 'laceration', 'haematoma', 'trauma'. We interrogated theatre records for operations coded as splenectomy and cross-referenced this with pathology. Records were reviewed for demographics, vital observations, documentation of American Association for the Surgery of Trauma (AAST) grading of splenic injury, subsequent management and outcomes. RESULTS: There were 126 patients identified with traumatic splenic injury, with male to female ratio three to one. Operative management was undertaken in 54/126 (43%) patients and selective non-operative management in the remaining. Splenic artery embolisation was undertaken in 5/126 (4%) and 2/126 underwent splenorrhaphy. Computed tomography was undertaken in 109/126 (87%) patients and AAST grading was reported in 18 (17%) patients. AAST grade reporting did not improve significantly when comparing the first 7.5 years with the latter (2/30, 7%; 16/79, 20%), respectively; p = 0.09). Selective non-operative management increased significantly over the studied period (14/34, 42%; 58/93, 62%; p = 0.04). The overall hospital mortality was 10.3%. DISCUSSION AND CONCLUSION: AAST grade reporting of splenic injury has remained sub-optimal over 15 years. Despite progression towards selective non-operative management, operative intervention remained unacceptably high, with splenectomy being the main therapeutic modality. Standardisation through an integrated multidisciplinary diagnostic and management pathway offers the optimal strategy to reduce trauma-induced splenectomy.

RESUMO

AIM: To assess the value of quantitative spleen and liver volume changes in predicting the survival of patients with primary sclerosing cholangitis (PSC). MATERIALS AND METHODS: This institutional review board-approved single-centre study included 89 PSC patients with baseline and follow-up liver imaging studies and laboratory data between 2000 and 2018. Change in spleen, total and lobar liver volumes, and lobar-to-total liver volume ratio was compared between patients with and without adverse outcome (liver transplantation, transplant waiting list, and death). Receiver operating characteristic (ROC) and Kaplan-Meier analysis were performed to identify the volumetric threshold for prediction of outcome and show how these thresholds predict survival, respectively. A p-value of <0.05 was considered statistically significant. RESULTS: The present cohort included 53 men (60%), with mean age of 42 years at baseline. The only volumetric parameters with significant differences in change between patients with and without adverse outcome were spleen volume (p<0.001) and left-to-total liver volume ratio (L/T; p=0.025). The probability of transplant-free survival at 36 months was 59.1% versus 11.9% for patients with spleen volume change <50 ml versus ≥50 ml, respectively (AUC=0.731); and 61.3% versus 13.8% for patients with L/T change <0.04 versus ≥0.04, respectively (AUC=0.638). The patients with changes below the cut-off in both spleen volume and L/T, had a higher probability of transplant-free survival at 36 months (76.8%), compared to those with change at or below the cut-offs in one or both of these two parameters (36.7%, 15%, respectively; p=0.001). CONCLUSION: Spleen volume change and L/T change might be useful biomarkers for prediction of transplant-free survival in patients with PSC.

RESUMO

BACKGROUND AND AIM: Septic emboli (SE) associated with infectious endocarditis (IE) can result in splenic abscesses and infectious intracranial aneurysms (IIA). We investigated the impact of SE on patient outcomes following surgery for IE. METHOD: From January-2000 to October-2015, all patients with surgical IE (n = 437) were evaluated for incidence and management of SE. RESULTS: Overall SE was found in 46/437 (10.52%) patients (n = 17 spleen, 13 brain, and 16 both). No mortality was seen in the brain emboli groups, but in the splenic abscess group the in-hospital mortality was 8.69% (n = 4); and was associated with Age >35 (OR = 2.63, 1.65-4.20) and congestive heart failure (OR = 14.40, 1.23-168.50). Patients with splenic emboli had excellent mid-term outcome following discharge (100% survival at 4-years). Splenic emboli requiring splenectomy was predicted by a >20 mm valve vegetation (OR = 1.37, 1.056-1.77) and WBC >12000 cells/mm (OR = 5.58, 1.2-26.3). No patient with streptococcus-viridians infection had a nonviable spleen (OR = 0.67, 0.53-0.85). Postoperative acute-kidney-injury was higher in the splenectomy group (45.45% vs 9%) (p = 0.027). There were 6 patients with symptomatic IIAs that required coiling/clipping which was associated with age <30 years, (OR = 6.09, 1.10-33.55). Survival in patients with cerebral emboli decreased to 78% at 3-4 years. Patients with both splenic and brain emboli had a 92% survival rate at 1-year and 77% at 2-4 years. CONCLUSION: Septic emboli is common in endocarditis patients. Patients with high preoperative WBC level and large valve vegetations require CT imaging of the spleen. Both spleen and brain interventions in the setting of IE can be performed safely with excellent early and mid-term outcomes.

RESUMO

OBJECTIVE: To determine the percentage of dogs surviving to hospital discharge and identify factors associated with death prior to hospital discharge among dogs undergoing surgery because of primary splenic torsion (PST). DESIGN: Retrospective case series. ANIMALS: 102 client-owned dogs. PROCEDURES: Medical records of dogs with a confirmed diagnosis of PST that underwent surgery between August 1992 and May 2014 were reviewed. History, signalment, results of physical examination and preoperative bloodwork, method of splenectomy, concurrent surgical procedures, perioperative complications, duration of hospital stay, splenic histopathologic findings, and details of follow-up were recorded. Best-fit multivariate logistic regression was performed to identify perioperative factors associated with survival to hospital discharge. RESULTS: 93 of the 102 (91.2%) dogs survived to hospital discharge. German Shepherd Dogs (24/102 [23.5%]), Great Danes (15/102 [14.7%]), and English Bulldogs (12/102 [11.8%]) accounted for 50% of cases. Risk factors significantly associated with death prior to hospital discharge included septic peritonitis at initial examination (OR, 32.4; 95% confidence interval [CI], 2.1 to 502.0), intraoperative hemorrhage (OR, 22.6; 95% CI, 1.8 to 289.8), and postoperative development of respiratory distress (OR, 35.7; 95% CI, 2.7 to 466.0). Histopathologic evidence of splenic neoplasia was not found in any case. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that the prognosis for dogs undergoing splenectomy because of PST was favorable. Several risk factors for death prior to discharge were identified, including preexisting septic peritonitis, intraoperative hemorrhage, and postoperative development of respiratory distress.

RESUMO

BACKGROUND: Splenectomy is performed frequently for various and primarily hematologic indications in children and adolescents. We analyzed the long-term outcome after splenectomy (median, 8.7 years) focusing on sepsis, portal vein thrombosis (PVT), and retained accessory spleen. METHODS: In total, 141 consecutive children after open (n = 89; 63%) or laparoscopic (n = 52; 37%) splenectomy from 1991 to 2010 were followed up through nationwide registries for septic infections, PVT, and causes of death. Sixty-six patients (58% of survivors) answered a structured questionnaire on infections, abdominal symptoms, and general health, and 64 (laparoscopic n = 26, open n = 38) consented to ultrasonography of the portal venous system. RESULTS: Median operation age was 8.8 years (range, 1.0-22). Reoperations were required for bleeding after open procedures (n = 1) and retained accessory spleen after laparoscopic procedures (n = 3). Postsplenectomy sepsis occurred after a median of 1.7 years (range, 0.2-5.9) in 11 patients (8%), of whom 10 had an underlying immunodeficiency. No cases of PVT were observed, although the median portal vein flow was 1,130 mL/min (range, 440-2200) and diameter was 9.9 mm (range, 7-15) at a median follow-up of 9.5 years (range, 2.0-22) after splenectomy. Twenty-seven patients (19%) died after 8.7 years (0.03-23.00). The most common cause of death was the underlying malignancy (n = 15), with sepsis being an additional cause of death in 5 patients. CONCLUSION: Postsplenectomy sepsis was associated almost exclusively with an underlying immunodeficiency with a high mortality rate. No PVT was observed. The overall risk of retained accessory spleen was around 7%, and was slightly greater after laparoscopic operation.

RESUMO

BACKGROUND: Complications of cirrhosis may persist after liver transplantation. When indicated, partial splenic embolization (PSE) is an alternative to splenectomy but can cause severe infection. The identification of modifiable risk factors when performing PSE in immunocompromised liver transplant recipients may help reduce the risk of severe infection. METHODS: Data were collected retrospectively for all PSE performed after liver transplantation at a single institution and included demographics, etiology of liver disease, indication for PSE, vaccination status, laboratory findings, procedural details, extent and pattern of splenic infarction, hospital length-of-stay, readmissions, procedural complications, and mortality. Statistical analysis included 2-tailed t test, Fisher exact test, and Kaplan-Meier survival curves, with significance defined as P < .05. RESULTS: Sixteen patients received 22 embolizations, with 11 patients undergoing a single session and 5 patients undergoing multiple sessions. Indications included hypersplenism, gastrointestinal hemorrhage, ascites, and autoimmune hemolytic anemia. PSE produced significant and sustained cell count increases, improved ascites, and controlled hemorrhage. Splenic abscess, septic shock, need for splenectomy, and PSE-related mortality were seen in the group with large confluent splenic infarction but not in peripheral/wedge-shaped infarction. Multiple-session PSE exclusively using particles for embolization correlated with the pattern of peripheral/wedge-shaped infarction and avoided severe infection and PSE-related mortality. CONCLUSIONS: PSE in the immunosuppressed liver transplant recipient is an effective alternative to splenectomy, but carries substantial infectious risk. The risk is decreased when PSE performed with polyvinyl alcohol particles results in a pattern of peripheral/wedge-shaped infarction, which correlates with smaller infarction volumes, favorable length-of-stay, and minimal risk of abscess, sepsis, and mortality.

RESUMO

OBJECTIVE: To characterize the deaths of 193 children with sickle cell disease screened by a neonatal program from 1998 to 2012 and contrast the initial years with the final years. METHODS: Deaths were identified by active surveillance of children absent to scheduled appointments in Blood Bank Clinical Centers (Hemominas). Clinical and epidemiological data came from death certificates, neonatal screening database, medical records, and family interviews. RESULTS: Between 1998 and 2012, 3,617,919 children were screened and 2,591 had sickle cell disease (1:1,400). There were 193 deaths (7.4%): 153 with SS/Sß0-talassemia, 34 SC and 6 Sß+thalassemia; 76.7% were younger than five years; 78% died in the hospital and 21% at home or in transit. The main causes of death were infection (45%), indeterminate (28%), and acute splenic sequestration (14%). In 46% of death certificates, the term "sickle cell" was not recorded. Seven-year death rate for children born between 1998 and 2005 was 5.43% versus 5.12% for those born between 2005 and 2012 (p = 0.72). Medical care was provided to 75% of children; 24% were unassisted. Medical care was provided within 6 hours of symptom onset in only half of the interviewed cases. In 40.5% of cases, death occurred within the first 24 hours. Low family income was recorded in 90% of cases, and illiteracy in 5%. CONCLUSIONS: Although comprehensive and effective, neonatal screening for sickle cell disease was not sufficient to significantly reduce mortality in a newborn screening program. Economic and social development and increase of the knowledge on sickle cell disease among health professionals and family are needed to overcome excessive mortality. .


OBJETIVO: Caracterizar os 193 óbitos de crianças com doença falciforme diagnosticadas por programa de triagem neonatal entre 1998-2012 e comparar os primeiros com os últimos anos. MÉTODOS: Os óbitos foram identificados pela busca ativa das crianças ausentes nas consultas agendadas nos hemocentros. Dados clínicos e epidemiológicos provieram dos documentos de óbito, banco de dados da triagem neonatal, prontuários médicos e das entrevistas com parentes. RESULTADOS: Entre 1998-2012 foram triadas 3.617.919 crianças, 2.591 com doença falciforme (1:1.400). Ocorreram 193 óbitos (7,4%): 153 com SS/Sß0-talassemia, 34 SC e 6 Sß+-talassemia; 76,7% em crianças com menos de cinco anos; 78% faleceram em hospitais e 21% em domicílio ou trânsito. Causas principais do óbito: 45% infecção, 28% indeterminada, 14% sequestro esplênico agudo. Em 46% dos documentos de óbito, não houve registro do termo "falciforme". A taxa de mortalidade até sete anos das crianças nascidas entre 1998-2005 foi 5,43% versus 5,12%, entre 2005-2012 (p = 0,72). Receberam assistência médica 75% das crianças; 24% ficaram desassistidas. Pelas entrevistas, atendimento médico teria ocorrido nas primeiras seis horas do início dos sintomas em metade dos casos. O óbito ocorreu em 40,5% dos casos, nas primeiras 24 horas. Baixa renda familiar foi registrada em 90% dos casos e analfabetismo em 5%. CONCLUSÕES: A triagem para doença falciforme, mesmo abrangente e eficaz, não foi suficiente para reduzir significativamente a mortalidade no Programa de Triagem Neonatal. Necessita-se de desenvolvimento econômico e social do Estado e ampliação, pela educação continuada, do conhecimento sobre a doença falciforme entre os profissionais de saúde e parentes. .

RESUMO

BACKGROUND: Blunt spleen injury is generally taken as major trauma which is potentially lethal. However, the management strategy has progressively changed to noninvasive treatment over the decade. This study aimed to (1) find out the incidence and trend of strategy change; (2) investigate the effect of change on the mortality rate over the study period; and (3) evaluate the risk factors of mortality. MATERIALS AND METHODS: We utilized nationwide population-based data to explore the incidence of BSI during a 12-year study period. The demographic characteristics, including gender, age, surgical intervention, blood transfusion, availability of CT scans, and numbers of coexisting injuries, were collected for analysis. Mortality, hospital length of stay, and cost were as outcome variables. RESULTS: 578 splenic injuries were recorded with an estimated incidence of 48 per million per year. The average 12-year overall mortality rate during hospital stay was 5.28% (29/549). There is a trend of decreasing operative management in patients (X (2), P = 0.004). The risk factors for mortality in BSI from a multivariate logistic regression analysis were amount of transfusion (OR 1.033, P < 0.001, CI 1.017-1.049), with or without CT obtained (OR 0.347, P = 0.026, CI 0.158-0.889), and numbers of coexisting injuries (OR 1.346, P = 0.043, CI 1.010-1.842). CONCLUSION: Although uncommon of BSI, management strategy is obviously changed to nonoperative treatment without increasing mortality and blood transfusion under the increase of CT utilization. Patients with more coexisting injuries and more blood transfusion had higher mortality.

RESUMO

OBJECTIVE: To analyze the clinical manifestations, diagnosis, treatment and prognosis of patients with splenic abscess. METHOD: The clinical data, including baseline clinical data, clinical features, past history, pathogen culture result, treatment and the prognosis were retrospectively analyzed in the patients with the discharge diagnosis splenic abscess from January 1991 to March 2012 in Peking Union Medical College Hospital. RESULTS: The media time from onset to Peking Union Medical College Hospital of the 19 patients were 29 days. Among them, 9 patients were cured, 8 were improved and 2 died. Risk factors, such as tumor burden, diabetes, and using immunosuppressive agents etc, can be found in most patients with splenic abscess. All the 19 patients had splenic image changes and non-specific clinical features. The most common three clinical symptoms were fever (18 cases), chills (12 cases) and shivering (11 cases). The most common three signs were abdominal tenderness (9 cases), left upper quadrant sensitive to percussion (7 cases) and splenomegaly (4 cases). The most common etiological culture results were gram negative bacilli (9 cases), gram positive coccus (8 cases), and fungi (4 cases). CONCLUSIONS: Clinical features are non-specific in splenic abscess patients. Related exam such as ultrasound should be performed on patients with splenic abscess risk factors to avoid misdiagnosis. Empiric antibiotic administration should begin right after the diagnosis based on the image. Pathogen culture should be timely conducted after pus collection. Individual therapeutical protocol should be chosen according to patient's condition.

RESUMO

BACKGROUND/AIMS: Hepatic or splenic lesions in hematologic patients are not defined well because they are not easy to evaluate due to limitations of invasive procedures. Management typically depends on the clinical diagnosis with few microbiological data. METHODS: We reviewed the medical records of consecutive hematologic patients with hepatic or splenic lesions in the infectious diseases unit from April 2009 to December 2010 at the Catholic Hematopoietic Stem Cell Transplantation Center in Korea. RESULTS: Twenty-six patients were identified. Their mean age was 46.0 ± 14.7 years, and 16 (61.5%) were male. Underlying diseases were acute myelogenous leukemia (n = 15, 57.7%) and myelodysplastic syndrome (n = 6, 23.1%). Among the nine nontuberculous infectious lesions, two bacterial, six fungal, and one combined infection were identified. The numbers of confirmed, probable, and possible tuberculosis (TB) cases were one, three, and four, respectively. Two patients had concurrent pulmonary TB. QuantiFERON-TB Gold In-Tube (QFT-GIT, Cellestis Ltd.) was positive in seven cases, among which six were diagnosed with TB. The sensitivity and specificity of QFT-GIT were 75% and 81.3%. Nine (34.6%) were defined as noninfectious causes. CONCLUSIONS: Causes of hepatic or splenic lesion in hematologic patients were diverse including TB, non-TB organisms, and noninfectious origins. TB should be considered for patients not responding to antibacterial or antifungal drugs, even in the absence of direct microbiological evidence. QFT-GIT may be useful for a differential diagnosis of hepatosplenic lesions in hematologic patients.

RESUMO

INTRODUCTION: Total splenectomy leads to an immunocompromised state, with an increased lifetime risk of infection. The lifetime risk of developing overwhelming postsplenectomy infection is 5 %, with a mortality rate of approximately 50 %. In addition to vaccination and antibiotic prophylaxis, partial splenectomy is believed to improve patient safety. METHODS: We performed partial splenectomy in seven patients using a radiofrequency (RF) technique with Habib® needles. In seven patients, an open access partial splenectomy was performed. In three patients, a partial splenectomy was performed simultaneously with intraabdominal tumour resection. In two patients, the upper pole of the spleen was removed due to tumours of the spleen. In one patient, a large symptomatic splenic cyst was resected and in another patient, a partial splenectomy was performed due to trauma. RF was applied using Habib® needles (AngioDynamics, Manchester, GA, 31816, USA). RESULTS: The partial splenectomy procedures were easy and safe in all seven patients. The RF application with the Habib® needles led to primary haemostasis. The blood loss was less than 50 ml in all cases. After a minimum follow-up of 1 year, there were no cases of infections or other adverse events related to the previous partial splenectomy. CONCLUSION: In our experience, partial splenectomy with Habib® needles is easy to perform and safe for the patient. Thus, radiofrequency resection is a good alternative to total splenectomy in many patients and reduces the risk of postsplenectomy infections.

RESUMO

This retrospective study describes a technique and evaluates outcome associated with laparoscopic splenic biopsy in dogs and cats. Medical records of dogs (n = 10) and cats (n = 5) that had a laparoscopic splenic biopsy performed as part of their diagnostic evaluation for systemic disease were evaluated. Splenic biopsies were performed with the patient in dorsal recumbency using a two-portal approach. In some cases, concurrent organ biopsy was also performed. A pair of 5 mm cup biopsy forceps was used for biopsy collection, and an absorbable gelatin hemostatic sponge was placed at the biopsy site to aid in hemostasis. All patients recovered without major complications. Conversion to an open surgical approach was not required. Median survival time was 180 days, and nine patients were alive at the time of manuscript preparation. Four patients were diagnosed with neoplasia; however, only one had neoplasia involving the spleen. Median survival time for the nonneoplasia group (n = 11) was 300 days. Eight of those patients were alive at time of manuscript preparation. Minimal morbidity was observed in this cohort of clinical patients. Histopathology may be preferred over cytology in some clinical situations, and laparoscopic splenic biopsy provides a minimally invasive diagnostic option.

RESUMO

The purpose of this study was to define a population of visceral heterotaxy and to investigate the incidence of bacterial sepsis in the current era of universal pediatric pneumococcal immunization. Pediatric echocardiography and radiology databases, along with electronic medical records, were searched for patients followed-up since birth between 1999 and 2009 with either asplenia or polysplenia and cardiac anatomy consistent with heterotaxy syndrome. A total of 29 patients were identified. Seven patients (24%) had a total of 8 sepsis events, and 6 patients (86%) developed sepsis while taking appropriately prescribed antibiotic prophylaxis. Of the patients with sepsis, 5 had polysplenia and 2 had asplenia. Sixty-two percent of sepsis events were nosocomially acquired. No cases of pneumococcal sepsis occurred after the introduction of the conjugated pneumococcal vaccination to the pediatric vaccination schedule. Bacterial sepsis was associated with a 44% mortality rate. An unexpected finding in 3 patients with visceral heterotaxy, asplenia, and an interrupted inferior vena cava (IVC) as the only anomaly on echocardiography was associated intestinal malrotation. Children with visceral heterotaxy remain at significant risk of life-threatening bacterial infection. In addition, the finding of interrupted IVC on echocardiography should prompt screening for intestinal malrotation, even in the absence of additional structural heart disease.

RESUMO

OBJECTIVES: Invasive fungal infections (IFI) are a significant cause of morbidity and mortality in hematopoietic stem cell transplant (HSCT) recipients. Hepatosplenic candidiasis (HSC) is defined as a distinct form of invasive candidiasis, with liver, spleen, and kidney involvement, in patients with hematological disorders. METHODS: The charts of 255 patients (male/female 168/87; median age 35 (range 16-71) years) who were evaluated pre-HSCT at the Gazi University Hospital Stem Cell Transplantation Unit between 2003 and 2008, were retrospectively reviewed. RESULTS: HSC, which was demonstrated in six (2.3%) patients, was found to be more common in allogeneic HSCT recipients than in autologous HSCT recipients and in patients who had received two or more previous chemotherapy courses than in patients who had received fewer than two (p>0.05). Patients with HSC tended to have a worse performance status than patients without HSC according to the World Health Organization (p=0.001) and Karnofsky scale (p=0.007). Pre-transplantation ferritin (p=0.008) and acute phase reactant levels, including erythrocyte sedimentation rate (p=0.025) and C-reactive protein (p=0.007), were significantly higher in patients with HSC than in patients without HSC. CONCLUSIONS: This study shows the predictive role of pre-transplantation ferritin levels in selecting a subset of patients at increased risk for HSC. Pre-transplantation risk assessment and targeted strategies might lower the morbidity and mortality of IFI in HSCT recipients.

RESUMO

OBJECTIVE: To determine the optimal surgical management of splenic injury encountered during colectomy. DESIGN: Retrospective review from 1992 to 2007. SETTING: Mayo Clinic in Rochester, Minnesota, a tertiary care center. PATIENTS: A cohort of patients who sustained splenic injury during colectomy from 1992 to 2007. MAIN OUTCOME MEASURES: Overall 30-day major morbidity and mortality and overall 5-year survival. RESULTS: Of 13,897 colectomies, we identified 59 splenic injuries (0.42%). Of these, 33 (56%) were in men; there was a median age of 68 years (range, 30-93 years) and a median body mass index of 25.5 (range, 15-54). Thirty-seven injuries (63%) occurred during elective surgery, 6 (10%) occurred without splenic flexure mobilization, and 5 (8.4%) occurred during minimally invasive surgery. Injury was successfully managed by primary repair in 10 (17%), splenorrhaphy in 4 (7%), and splenectomy in 45 cases (76%). Four injuries (7%) were unrecognized and resulted in reoperation and splenectomy. Multiple attempts at splenic salvage were performed in 30 (51%); of these, 21 (70%) required splenectomy. More than 2 attempts at salvage was associated with splenectomy (P = .03). The 30-day major morbidity and mortality rates were 34% and 17%, respectively. Sepsis was the most common complication, with no confirmed episodes of postsplenectomy sepsis. Median survival after splenic injury was 7.25 years. There was no significant association between the surgical management of splenic injuries and short- or long-term outcomes. CONCLUSIONS: Splenic injury is an infrequent but morbid complication. Splenic salvage is frequently unsuccessful; our data suggest that surgeons should not be reluctant to perform splenectomy when initial repair attempts fail.

RESUMO

BACKGROUND: Laparoscopic splenectomy (LS) is the standard procedure for normal size or moderately enlarged spleens; open splenectomy (OS) is preferred in cases of splenomegaly. In this study, indications for and complications of open and laparoscopic splenectomy were analyzed, with the aim to identify patients who will benefit from either technique. METHOD: A consecutive series of 52 patients undergoing elective open or laparoscopic splenectomy between January 2001 and December 2006 was analyzed. Spleen volume was calculated as length x width x depth from the pathologist's measurements. RESULTS: LS was performed in 25 patients with a median age of 41 years (range = 24-65). OS was performed in 27 patients with a median age of 60 years (range = 24-86) (p < 0.001). Conversion to OS was necessary in two patients (8%). Operation time was significantly shorter in LS (p < 0.05). Spleen volume was significantly greater in patients who underwent open (median = 2520 ml, range = 150-16,800 ml) versus laparoscopic (median = 648 ml, range = 150-4860 ml) splenectomy (p = 0.001). In 36% of all laparoscopic procedures, spleen volume exceeded 1000 ml. The underlying disease was mainly immunothrombocytopenia in LS patients and lymphoma and osteomyelofibrosis in OS patients. Five patients died after OS. Significantly more patients were hospitalized longer than 7 days following OS than following LS (p < 0.05). Overall complication rate was higher after OS (LS, 8; OS, 13 patients; p < 0.05). CONCLUSIONS: LS was preferred in younger patients with moderate splenomegaly, while massive splenomegaly mostly led to OS. In view of the absence of technique-related differences, LS can primarily be attempted in all patients.

RESUMO

Selective breeding of animals for increased innate resistance offers an attractive strategy to control disease in agriculture. However, this approach is limited by an incomplete knowledge of the heritability, duration, and mechanism(s) of resistance, as well as the impact of selection on the immune response to unrelated pathogens. Herein, as part of a rainbow trout broodstock improvement program, we evaluated factors involved in resistance against a bacterial disease agent, Flavobacterium psychrophilum. In 2005, 71 full-sibling crosses, weighing an average of 2.4 g, were screened, and resistant and susceptible crosses were identified. Naive cohorts were evaluated at 10 and 800 g in size, and most maintained their original relative resistant or susceptible phenotypes, indicating that these traits were stable as size increased >300-fold. During the course of these studies, we observed that the normalized spleen weights of the resistant fish crosses were greater than those of the susceptible fish crosses. To test for direct association, we determined the spleen-somatic index of 103 fish crosses; created high, medium, and low spleen-index groups; and determined survival following challenge with F. psychrophilum or Yersinia ruckeri. Consistent with our previous observations, trout with larger spleen indices were significantly more resistant to F. psychrophilum challenge; however, this result was pathogen-specific, as there was no correlation of spleen size with survival following Y. ruckeri challenge. To our knowledge, this is the first report of a positive association between spleen size and disease resistance in a teleost fish. Further evaluation of spleen index as an indirect measure of disease resistance is warranted.

RESUMO

The aim of the study is to elucidate premorbid grounds, diagnostic and clinical peculiarities, as well as medical and surgical management of non-parasitic spleen abscess. We study 6 cases, with median age 56.7 years, men/women ratio--2:1. Onset-diagnosis period was of median 20 days. In 5 cases (83.3%) spleen abscess developed in immune compromised patients (diabetes mellitus, liver cirrhosis, pancreatitis) and in one case (16.7%) subsequent to blunt abdominal trauma. Clinically, patients presented fever, weight loss and pain in the left upper quadrant of the abdomen. The imaging data (USG, CT, and Rx-thoracic) performed prior to surgery confirmed the diagnosis. USG revealed splenic injury in 80%, CT had a 100% sensibility and thoracic Rx revealed left-side pleuro-pulmonary reaction in 83% of cases. Bacteriological test was positive in 50% of cases. One death was recorded in first 24 hours after surgery. The rest of the cases had a favorable evolution, although, in 2 cases a left subphrenic abscess was noticed, one requiring drainage; in one case--colonic fistula, which closed spontaneously. Although, it's a rare pathology, an early diagnosis is as important, as impossible, and it's delay exhausts the organism and increases the postoperative morbidity rate, splenectomy remaining the safest method of treatment.
