The elusive spleen.

INTRODUCTION: The aim of this study was to review the experience of general surgeons performing splenectomy in a district general hospital. The outcomes are discussed together with potential reasons for the increasing rarity of the procedure. METHODS: A retrospective cohort study was carried out of all patients undergoing splenectomy (as identified by a single trust pathology department on receipt of splenic samples) between 1 January 2000 and 1 May 2017. Case notes and computer systems were interrogated for data on operating surgeon, patient demographics, diagnosis, surgical approach (laparoscopic/open/converted to open), critical care admission and 30-day mortality. RESULTS: During the study period, 170 consecutive splenectomies were undertaken by 24 different operating surgeons. There were on average 5.8 planned and 4.2 unplanned splenectomies per year. The 30-day mortality rate for all splenectomies was 8.8%, with an elective 30-day mortality rate of 2.0%. Only 3 of the current consultant surgeons had undertaken more than 6 cases over the 17-year study period. Some senior consultants had not performed any splenectomies (either planned or unplanned) during the 17-year study period. CONCLUSIONS: Splenectomy is required ever more rarely and experience as a district general hospital consultant is limited. Possible reasons for this include improvements in medical management of haematological diseases, the increasing use of conservative and radiological management for traumatic splenic injury, and a reduction in trauma cases and diversion of such cases to major trauma centres. Trainees and consultants must seek experience during specialty training or via cadaveric training in order to demonstrate competence.

Splenectomy results from an 18-year single centre experience.

INTRODUCTION: Splenectomy is performed both as an emergency procedure following trauma and electively when indicated for haematological disease. Postsplenectomy patients receive immunotherapy vaccines and continuous antibiotic prophylaxis. Despite well documented concerns regarding complications and overwhelming postsplenectomy infection (OPSI) risk, there appears to be only a small amount of consistent data on long-term outcomes. The authors therefore present their postsplenectomy patient outcomes over an 18-year follow-up period. METHODS: One hundred and five postsplenectomy patients operated on between 1991 and 2011 were identified from pathology codes and their case notes were reviewed. Eighty-eight patients (83.8%) were followed up for at least five years or until death. RESULTS: Of the 105 splenectomy patients (58 were male), the median age was 54 years (range: 10-87 years) and the median survival was 80 months. Operative morbidity and mortality rates were 21.0% (n=22) and 8.6% (n=9) respectively. Thirty-seven patients (27 males) underwent an emergency splenectomy with a median age, operative morbidity and operative mortality of 51 years, 13.5% and 21.6% (n=8) respectively. This compares with 68 patients (35 males) undergoing an elective splenectomy with the same parameters respectively of 55 years, 25.0% and 1.5% (n=1). Excluding operative deaths, multivariate analysis revealed age (p=0.002) as the only significant and independent prognostic indicator. Immunotherapy and antibiotic prophylaxis rates for the emergency cohort were 92.6% and 88.9% respectively, compared with 90.2% and 93.4% for the elective cohort. At follow-up, no patients were readmitted with OPSI. CONCLUSIONS: Over an 18-year period and a diverse indication for splenectomy, we have identified no evidence of OPSI. However, a significant operative mortality was associated with traumatic splenic rupture.

[The organ-preserving surgical treatment of the splenic rupture after the blunt abdominal trauma].

The outcomes of 383 cases of heavy combined traumas (n=273) and isolated (n=110) closed injuries of the abdomen with spleen damage were analyzed. The overall mortality was 11.74% (n=45), whereas the mortality rate during the first day after admission was 7.83% (n=30). Removal of a spleen was executed at 228 patients. The spleen-preserving operation with ligation of splenic artery, was performed in 155 patients. The optimal level of the splenic artery ligation proved to be in its proximal and median parts. The postoperative CT-angiogarphy and Doppler US scanning together with the three-dimensional reconstruction confirmed that blood supply of the body and tail of the pancreas was satisfactory thanks to the natural collateral blood circulation. The dramatic decrease in lethality and of postoperative complication rates allows to consider spleen-preserving resections to be a good alternative to spleenectomy.

[Objective assessment of trauma severity in patients with spleen injuries].

The work presents an analysis of condition severity of 139 casualties with isolated and combined spleen injuries on admission to a surgical hospital. The assessment of condition severity was made using the traditional gradation and score scale VPH-SP. The degree of the severity of combined trauma of the spleen was determined by the scales ISS. The investigation showed that the scale ISS and VPH-SP allowed objective measurement of the condition severity of patients with spleen trauma. The score assessment facilitated early detection of the severe category of the patients, determined the diagnostic algorithm and the well-timed medical aid.

[The risk of death from splenic ruptures by polytrauma among children].

The retrospective analysis of polytrauma with lethal outcome in 105 children showed that splenic injury had 31.4% of children. It was twice more often than liver injury, though the hemoperitoneum volume by liver injury exceeds that by spleen trauma (846.1±753.8 ml vs. 311±270.3 ml; p<0.002). The risk of death of intraabdominal bleeding by the spleen rupture is considerably low (OR 0.16; 95% CI 0.019-1.34; p=0.04). Nevertheless, the hemothorax by the spleen injury was much more significant than hemoperitoneum (977±866.9 ml vs. 311±270.3 ml; p<0.0003). The risk of death of intrathoracic bleeding by the spleen rupture is 45 times higher than of intraabdominal. The degree of splenic injury poorly correlates with the traumatic mechanism and the hemoperitoneum volume. The chances of the immediate death is considerably low (OR 0.09; 95% CI 0.0096-0.84; p<0.017). The main reasons of death by polytrauma remain brain injury, hemorrhagic shock after injury of thoracic cavity and traumatic shock.

Delayed spleen rupture after blunt abdominal trauma (case report).

The aim of the article was to present and discuss the phenomenon of delayed fatal spleen rupture case. A 13-year-old boy was referred to hospital because of his poor general condition, convulsions, tachypnea, shallow breathing, severe paleness, abdominal tenderness, decrease in blood pressure, low blood hemoglobin levels, leukocytosis. Abdominal pain complaints began second day night, after abdominal trauma during soccer game with classmates. Autopsy macroscopic examination revealed coagulated blood in abdominal cavity and large perisplenic haematama. Spleen with a big subcapsular and intrasplenic hematoma was observed on dissection. It is concluded that early diagnosis is the most important measure to reduce mortality. In terms of autopsy examination, proper investigation during forensic autopsy will contribute in understanding the pathophysiology of this phenomenon.

[Non-traumatic rupture of the spleen]. / Miltruptuur zonder trauma.

BACKGROUND: A non-traumatic rupture of the spleen is a rare, serious condition with a high mortality rate. This sort of rupture can occur in a healthy patient or in patients with an underlying disease such as an infection or a haematological disorder. CASE DESCRIPTION: Here we describe a 52-year-old man who had Legionella pneumonia and suffered a spontaneous rupture of the spleen. He had to undergo a splenectomy following an unsuccessful embolisation of the lienal artery. He recovered. In the second patient, a 73-year-old man with monoclonal gammopathy, rupture of the spleen was caused by amyloidosis of the spleen. CONCLUSION: Rupture of the spleen can cause life threatening haemorrhage, so early recognition is important.

Systematic review of atraumatic splenic rupture.

BACKGROUND: Atraumatic splenic rupture (ASR) is an ill defined clinicopathological entity. METHODS: The aim was to characterize aetiological and risk factors for ASR-related mortality in order to aid disease classification and treatment. A systematic literature review (1980-2008) was undertaken and logistic regression analysis employed. RESULTS: Some 632 publications reporting 845 patients were identified. The spleen was normal in 7.0 per cent (atraumatic-idiopathic rupture). One, two or three aetiological factors were found in 84.1, 8.2 and 0.7 per cent respectively (atraumatic-pathological rupture). Six major aetiological groups were defined: neoplastic (30.3 per cent), infectious (27.3 per cent), inflammatory, non-infectious (20.0 per cent), drug- and treatment-related (9.2 per cent) and mechanical (6.8 per cent) disorders, and normal spleen (6.4 per cent). Treatment comprised total splenectomy (84.1 per cent), organ-preserving surgery (1.2 per cent) or conservative measures (14.7 per cent). The ASR-related mortality rate was 12.2 per cent. Splenomegaly (P = 0.040), age above 40 years (P = 0.007) and neoplastic disorders (P = 0.008) were associated with increased ASR-related mortality on multivariable analysis. CONCLUSION: The condition can be classified simply into atraumatic-idiopathic (7.0 per cent) and atraumatic-pathological (93.0 per cent) splenic rupture. Splenomegaly, advanced age and neoplastic disorders are associated with increased ASR-related mortality.

Atraumatic splenic rupture in amyloidosis.

BACKGROUND: Splenic involvement in amyloidosis is rather frequent (5-10%). An atraumatic rupture of the affected spleen is however an extremely rare event. We report on a patient with undiagnosed amyloidosis who underwent emergency splenectomy for atraumatic splenic rupture. METHODS: Review of the literature and identification of 31 patients, including our own case report, with atraumatic splenic rupture in amyloidosis. Analysis of the clinical presentation, the surgical management, the nomenclature and definition of predisposing factors of splenic rupture. RESULTS: We identified 15 women and 16 men (mean age 53.3 +/- 12.4 years; median 52, range: 27-82 years) with an atraumatic splenic rupture. Easy skin bruisability and factor X deficiency were detected in four (13%) and five patients (16%), respectively. The diagnosis of splenic rupture was made either by computed tomography (n = 12), ultrasound (n = 5), exploratory laparotomy (n = 9) or autopsy (n = 4). All patients underwent surgery (n = 27) or autopsy (n = 4). Amyloidosis was previously diagnosed in nine patients (29%). In the remaining 22 patients (71%), the atraumatic splenic rupture represented the initial manifestation of amyloidosis. Twenty-five patients (81%) suffered from primary (AL) and four patients (13%) from secondary amyloidosis (AA). In two patients, the type of amyloidosis was not specified. A moderate splenomegaly was a common feature (68%) and the characteristic intraoperative finding was an extended subcapsular hematoma with a limited parenchymal laceration (65%). In five patients with known amyloidosis, the atraumatic splenic rupture was closely associated with autologous stem-cell transplantation (ASCT) (16%). Three patients were suffering from multiple myeloma (10%). A biopsy-proven amyloidotic liver involvement was present in 14 patients (45%), which lead to atraumatic liver rupture in two patients. The splenic rupture related 30-day mortality was 26% (8/31). CONCLUSIONS: Atraumatic splenic rupture in amyloidosis is associated with a high 30-day mortality. It occurs predominantly in patients with previously undiagnosed amyloidosis. A moderate splenomegaly, coagulation abnormalities (easy skin bruisability, factor X deficiency) and treatment of amyloidosis with ASCT are considered predisposing factors for an atraumatic splenic rupture.

Blunt assault is associated with failure of nonoperative management of the spleen independent of organ injury grade and despite lower overall injury severity.

OBJECTIVE: Nonoperative management (NOM) of blunt splenic injuries has become standard of care for its high success rate. We observe that many blunt assault (BA) patients fail NOM despite lower overall injury severity. We performed this study to determine whether BA is independently associated with failed initial NOM (FiNOM) of splenic injuries. METHODS: Using the Trauma Registry at our level I center, we reviewed data of all patients with blunt splenic injuries, who did not undergo immediate operative management of the spleen, admitted from January 1, 1992 to December 31, 2007. Initial NOM was defined as any patient who did not undergo immediate (< or =12 hours after admission) operative intervention for the spleen or did not undergo operation for the spleen at any time during the admission. FiNOM was defined as any patient who underwent operative management of the spleen greater than 12 hours after admission. Logistic regression was performed to determine whether BA was independently associated with FiNOM. RESULTS: FiNOM occurred in 57 of the 419 (13.6%) patients initially managed nonoperatively. FiNOM decreased significantly in non-BA patients from 15.8% (1992-1999) to 6.2% (2005-2007) (p = 0.05) over time. This was not true for BA patients (33.3% vs. 30%) (p = 0.78). FiNOM for BA patients was 36.1% (13 of 36) versus 11.5% (44 of 383) for all other mechanisms combined. FiNOM was increased across all Organ Injury Scale scores for the spleen in BA patients. BA was independently associated with FiNOM. CONCLUSIONS: BA is associated with FiNOM independent of severity of splenic injury. Despite an increasingly successful policy of NOM in all blunt splenic injuries, this does not apply for BA. BA should be an important factor considered when initial NOM is contemplated for blunt splenic injury because of the high failure rates compared with all other mechanisms.

Safety of early mobilization of patients with blunt solid organ injuries.

BACKGROUND: Many surgeons believe that early mobilization of patients with blunt solid organ injuries increases the risk of delayed hemorrhage. OBJECTIVE: To determine whether there is an association between the day of mobilization and rates of delayed hemorrhage from blunt solid organ injuries. DESIGN: Retrospective cohort study. Univariate and multivariate analyses were performed to determine the association of mobilization with delayed hemorrhage of a solid organ requiring laparotomy. SETTING: Level I trauma center. PATIENTS: Adults with blunt renal, hepatic, or splenic injuries were identified from a trauma registry. MAIN OUTCOME MEASURES: Medical records were used to determine the day of mobilization and to identify patients with delayed hemorrhage requiring laparotomy. RESULTS: Four hundred fifty-four patients with blunt solid organ injuries were admitted to the hospital for nonoperative management. Failure rates of nonoperative management were 4.0%, 1.0%, and 7.1% for renal, hepatic, and splenic injuries, respectively. No patients with renal or hepatic injuries failed secondary to delayed hemorrhage. Ten patients (5.5%) with splenic injuries failed secondary to delayed hemorrhage. Eighty-four percent of patients with renal injuries, 80% with hepatic injuries, and 77% with splenic injuries were mobilized within 72 hours of admission. Day of mobilization was not associated with delayed splenic rupture in multivariate analysis (odds ratio, 0.97; 95% confidence interval, 0.90-1.05). CONCLUSIONS: The timing of mobilization of patients with blunt solid organ injuries does not seem to contribute to delayed hemorrhage requiring laparotomy. Protocols incorporating periods of strict bed rest are unnecessary.

Is anything new in adult blunt splenic trauma?

Several decades ago, a shift occurred in the management of adult splenic injuries. Influenced by the experience in pediatric trauma patients, adult trauma surgeons began turning from mandatory operative treatment of all splenic injuries toward nonoperative management. Nonoperative treatment is now the most common method of management for patients with splenic injuries and is the most common method of splenic salvage. However, controversy exists about how to appropriately select patients for nonoperative treatment since bleeding from splenic injuries can incur significant morbidity and mortality. Recent refinements in the management of adult blunt splenic injuries will be reviewed.

[The importance of laparoscopy in blunt abdominal trauma]. / Der Stellenwert der Laparoskopie beim Abdominaltrauma.

The importance of laparoscopy in the management of blunt abdominal trauma should be evaluated. Therefore we retrospectively analysed all patients with blunt abdominal trauma treated in the Department of Surgery at the Carl-Thiem-Hospital Cottbus between 1998 and 2000. Within this period a total number of 53 patients with blunt abdominal trauma underwent operative treatment, 20 (37.7 %) of them had primary laparoscopy. Of the 11 cases where laparoscopic operation could be completed without conversion to exploratory laparotomy, 8 patients had intra-abdominal injuries and underwent sufficient laparoscopic treatment. The percentage of so called "negative" exploratory laparotomies within this study was 13.2 %. Our analysis suggests that laparoscopy should become firmly established in the diagnostic management and, if indicated, in the treatment of blunt abdominal trauma as well.

New insight for management of blunt splenic trauma: significant differences between young and elderly.

BACKGROUND/AIMS: Although highly successful in children and young patients, the non-operative management of blunt splenic injury in the elderly has yet to be clearly studied. The purpose of this study was to determine whether or not a relationship exists among the mechanism of injury, the grade of splenic injury, the associated injuries, and whether patterns of injury differ between the young group (younger than 60 years old) and the elderly group (60 years and older than 60 years). METHODOLOGY: One hundred and sixty-seven patients (116 young patients including 30 early deaths and 51 elderly patients including 20 early deaths) with blunt splenic injury were admitted to our clinic from 1983 to 1997. Computed tomography scans were interpreted in a blind fashion. In addition, the Injury Severity Score, Glasgow Coma Scale, blunt splenic injury grade, length of hospital stay, length of intensive care unit stay, survival, number of abdominal injuries and number of total diagnoses were investigated in both the young and elderly groups. The different types of management for blunt splenic injury were also studied. RESULTS: Higher injury severity scores, lower Glasgow Coma Scales, and higher mortality all indicated that the elderly were more severely injured than the young patients. The rate of non-operative treatment was also significantly greater for young patients than for elderly patients (62.8 vs. 32.3%, P < 0.05) and the rate of a splenectomy was significantly less for the young patients than for the elderly patients (29.1 vs. 51.6%, P < 0.05). Regarding infectious complications, the rates of pneumonia (14.0 vs. 23.1%, P < 0.05), subphrenic abscess (9.3 vs. 23.1%, P < 0.05), and urosepsis (7.0 vs. 23.1%, P < 0.05) was significantly greater for the elderly patients than for the young patients. The overall failure of non-operative management was 5.2% in the young patients and 9.8% in the elderly patients. CONCLUSIONS: The final selection of splenic management decision was individualized for each patient and based on multiple variables. For persistent hemodynamic instability or unresolved concerns for other individual pathologic conditions, aggressive management is recommended. In the absence of these two important conditions, the variables that predicted a need for operative intervention include an Injury Severity Score above 20 in younger and elderly patients; an American Association for the Surgery of Trauma splenic grade above III in elderly; a large hemoperitoneum on an initial computed tomography scan; the presence of active extravasation on an initial computed tomography scan; and high-energy mechanisms. In conclusion, selecting the optimal non-operative management of blunt splenic injury in elderly patients remains difficult. An aggressive initial operation is thus recommended because the specific fragility of the spleen and the decreased physiologic reserve in elderly patients is difficult to estimate, especially at small hospitals where performing emergency splenic angiography and treating embolisms is difficult.

Splenic injury in side impact motor vehicle collisions: effect of occupant restraints.

BACKGROUND: Side impact motor vehicle collisions (MVCs) are associated with higher morbidity and mortality compared with other types of MVCs. The stiffness of the lateral aspect of the vehicle and restraint use may play a role. The purpose of this study was to evaluate the role of restraint use, vehicle size, and compartment intrusion on the incidence of splenic injury in side impact MVCs. METHODS: The National Automotive Sampling System was used to identify drivers involved in side impact collisions for the years 1996 to 1998. The incidence of splenic injury in these collisions was compared according to restraint use, vehicle size, and magnitude of vehicle crush. Information on the perceived cause of splenic injuries sustained in the MVC was also obtained from National Automotive Sampling System investigator records. RESULTS: Overall, among drivers involved in side impact MVCs, restraint use was associated with a significantly reduced rate of mortality (odds ratio [OR], 0.40; p < 0.0001) and splenic injury (OR, 0.76; p < 0.0001). Restrained drivers of small vehicles (<2,500 lb), however, had a higher incidence of splenic injury in both minimal (lateral intrusion < 30 cm) (OR, 60.1; p < 0.0001) and severe (lateral intrusion > 30 cm) (OR, 4.0; p < 0.0001) magnitudes of vehicle crush on the driver's side of the vehicle. For both midsize (2,500-3,000 lb) and large (>3,000 lb) vehicles, restraint use was associated with a lower risk of splenic injury regardless of the magnitude of crush. In nearly all cases of splenic injury, the left vehicle interior was the source of injury. CONCLUSION: Overall, restraint use is associated with lower rates of splenic injury and mortality in side impacts. Despite this fact, restrained drivers of small vehicles have a higher risk of splenic injury after lateral impact MVCs when compared with unrestrained drivers. Evaluation of the combined role of restraint use, crash, and injury patterns may provide novel insight regarding vehicle safety design features.

Spontaneous rupture of malarial spleen: two case reports and review of literature.

Malaria has long been among the most common diseases in the southeast Anatolia region of Turkey. In 1992, 18676 cases were diagnosed in Turkey, and Diyarbakir city had the highest incidence (4168 cases), followed by SanliUrfa city (3578 cases). Malaria was especially common during 1994 and 1995, with 84345 and 82094 cases being diagnosed in these years, respectively. Spontaneous rupture of malarial spleen is rare. We saw two cases during 1998, which are reported herein. Both patients were male, and were receiving chloroquine treatment for an acute attack of malaria. One of the patients had developed abdominal pain and palpitations, followed by fainting. The other patient had abdominal pain and fever. Explorative laparotomy revealed an enlarged spleen in both patients. Splenectomy was performed in both patients. We have identified 15 episodes of spontaneous rupture of the spleen in the English language literature published since 1961. Because of increased travel to endemic areas and resistance to antimalarial drugs, malaria is a major medical problem that is becoming increasingly important to surgeons worldwide. Malaria is a particularly important problem in the southeast Anatolia region of Turkey. Prophylactic precautions should be taken by tourists who travel to this region, especially during the summer.

The current status of splenic preservation.

The recognition of the fundamental role of the spleen in the immune response has led to greater efforts to preserve the spleen after injury. Whenever possible, splenic preservation is the preferred treatment modality for both blunt and penetrating injuries. The past 2 decades have seen an evolution in the way this goal is accomplished. Operative splenic preservation achieved by splenorrhaphy as the most prevalent method for the management of splenic trauma has progressed to the nonoperative management of these injuries. The factor most responsible for bringing about this change has been the development of more sophisticated and accurate imaging techniques in the evaluation of these patients. Splenectomy should be avoided whenever possible, as the procedure continues to be associated with excessive transfusion requirements and increased postoperative sepsis rates.

[Spleen trauma]. / Les traumatismes de rate.

The spleen is the intraabdominal organ the most often injured in case of blunt abdominal trauma. Cases of fulminant infection after splenectomy, both in children and in adults, point to the importance of developing a conservative approach to spleen trauma: abstention from surgery, conservative surgery. Total splenectomy does have its indications resulting either from the general condition of the injured patient, or peroperative observations. Approximately 30% of patients operated for spleen trauma undergo total splenectomy. Over the last 10 years, the proportion of conservative surgery cases has declined as abstention is increasingly favored, being adopted in 50 to 70% of cases with a success rate of at least 90%. Currently two initial criteria and one evolution criteria guide the decision to abstain from surgery: hemodynamic stability and absence of another intraabdominal lesion requiring laparotomy; and limit number of packed red cell units transfused. The decision to abstain from surgery implies very rigorous clinical monitoring. Imaging protocols vary. Computed tomography signs predictive of recurrent bleeding and the development of arteriography techniques with embolization may further raise the rate of success after abstention from surgery.
