Abstract
PURPOSE To evaluate macro/microscopic viability of the upper pole (UP) in rats after 80 days of subtotal splenectomy preserving the upper pole (SSPUP). METHODS Twenty-five male Wistar rats were submitted to SSPUP. After 80 days, the rats were euthanized, and the remaining UP was evaluated macroscopically regarding appearance, color, consistency, length, width, thickness, and presence of fibrosis/necrosis; and microscopically regarding presence of red and white pulp, fibrosis/necrosis. RESULTS Two rats died during surgery and were removed from the statistical analysis. There was statistically significant increase in length and width between the pre and postoperative in the experimental group, with no significant difference in thickness. In the manipulation group, the macroscopic appearance of the spleen was normal in pre and postoperative, with viability preserved. In the experimental group, two UP of the spleen were not found during the second surgery. Macroscopically, it was observed absence of fibrosis and necrosis in all cases. Microscopically, the white and red pulp were intact in both groups. Two spleens of rats in the manipulation group presented areas with fibrosis and necrosis focus, which were not enough to be considered inviable. CONCLUSIONS The UP of the spleen remained viable in 91.3% of the cases.

Abstract
BACKGROUND Splenorrhaphy was once used to achieve splenic preservation in up to 40% of splenic injuries. With increasing use of nonoperative management and angioembolization, operative therapy is less common and splenic injuries treated operatively are usually high grade. Patients are often unstable, making splenic salvage unwise. Modern surgeons may no longer possess the knowledge to perform splenorrhaphy. METHODS The records of adult trauma patients with splenic injuries from September 2014 to November 2018 at an urban level I trauma center were reviewed retrospectively. Data including American Association for the Surgery of Trauma splenic organ injury scale, type of intervention, splenorrhaphy technique, and need for delayed splenectomy were collected. This contemporary cohort (CC) was compared to a historical cohort (HC) of splenic injuries at a single center from 1980 to 1989 (Ann Surg 1990; 211: 369). RESULTS From 2014 to 2018, 717 adult patients had splenic injuries. Initial management included 157 (21.9%) emergent splenectomy, 158 (22.0%) angiogram ± embolization, 371 (51.7%) observation, and only 10 (1.4%) splenorrhaphy. The HC included a total of 553 splenic injuries, of which 313 (56.6%) underwent splenectomy, while splenorrhaphy was performed in 240 (43.4%). Those who underwent splenorrhaphy in each cohort (CC vs HC) were compared. CONCLUSION The success rate of splenorrhaphy has not changed. However, splenorrhaphy now involves only electrocautery with topical hemostatic agents and is used primarily in low-grade injuries. Suture repair and partial splenectomy seem to be "lost arts" in modern trauma care.

Abstract
BACKGROUND The routine mobilization of the left colonic flexure as a standard procedure during left colonic/rectal resection is a controversial topic in open and minimally invasive surgery. According to some authors, this maneuver may increase the risk of iatrogenic spleen damage; for others this does not change the odds. Ligaments over-traction is the most frequent injury mechanism. Some documented risk factors are reported: laparotomic approach, male gender, vascular disease, cancer, diverticulitis, surgery performed in emergency-setting. The type of procedure influences the associated risk: transverse colectomy is the riskiest, followed by left colonic resection and pancolectomy. METHODS Retrospective original paper. Sample size - a total of 125 patients have been considered. 75 robotic left colonic resections (60%), 40 robotic rectal resections (32%) and 10 robotic pancolectomy (8%). Primary outcomes - 1) percentage of iatrogenic splenic injuries; 2) conversion rate. Secondary outcomes - 1) intra-/postoperative complications; 2) anastomotic leakage rate; 3) mortality. In order to avoid potential confounding factors and technical/expertise heterogeneity, all the procedures included have been performed using the same standardized operative technique and by the same experienced surgeon (P.C.G.). RESULTS We retrospectively analyzed 125 procedures. Primary outcomes - 1) iatrogenic splenic injuries: 0%; 2) conversion rate: 1.6%. Secondary outcomes - 1) intraoperative complications: 0%; 2) anastomotic leakage rate: 1 case of leakage out of 125 cases (1.3% of the left colectomy sub-sample); in this case the leakage was probably due to an infectious process rather than a vascular deficit; 3) mortality: 0%; 4) miscellanea postoperatory complications (small bowel obstructions, wound infection, pelvic collections, pneumonia and acute kidney injury) are detailed in the manuscript. CONCLUSIONS In our experience, and according to some of the literature data as well, during robotic left colonic/rectal resections the routine mobilization of the left flexure as a standard procedure is not a risk factor in terms of iatrogenic spleen injury rate. Conversely, this technique may be beneficial as it does not excessively extend the operative time, increases the surgical skills acquirement, and reduces the tension-related anastomotic ischemia. It also allows a better oncological dissection. Standard laparoscopic approach reduces the rate of spleen by almost 3.5 times in comparison to open surgery. The improved technical accuracy provided by the robotic platform may decrease the rate of splenic injury. More studies are needed on the topic to confirm our findings.

Abstract
PURPOSE To investigate the vitality of the spleen lower pole after subtotal splenectomy with suture to the stomach and after posterior peritoneal gastro-splenic membrane section, using macro and microscopic evaluations. METHODS Sixty Wistar rats were used in this study and were randomly distributed in the three groups: Group 1: (n=20), subtotal splenectomy with lower pole preservation, Group 2: (n=20) subtotal splenectomy with lower pole preservation and suture to the stomach, Group 3: subtotal splenectomy with lower pole preservation and posterior peritoneal gastrosplenic ligament section. The animals were sacrificed 45 days after the surgery and the spleen lower poles were removed for macroscopic and microscopic examination. RESULTS All animals in this series survived. No macroscopic differences were encountered between the groups. Microscopic evaluation observed statistic difference concerning fibrosis between group 1 and 3 (p ≤ 0.05), but the analysis for necrosis and inflammation presented no differences. CONCLUSION Vitality of the spleen lower pole after subtotal splenectomy is minimally modified when it is fixed to the stomach or when the posterior peritoneal gastrosplenic ligament is resected.

Abstract
PURPOSE: To evaluate the effect of hyperbaric oxygen therapy on the survival and weight of rats submitted to subtotal splenectomy and on the viability and growth of the inferior pole. METHODS: Forty Wistar rats underwent subtotal splenectomy with preservation of the inferior pole and distributed into two groups: Group A (n=20) - not treated with hyperbaric oxygen, Group B (n=20) - treated with hyperbaric oxygen. These groups were divided into two subgroups of 10 animals each, according to the time of euthanasia, 15th and 45th days. The survival and weight of the animals were recorded. The inferior pole was measured, weighed and morphologically analyzed. RESULTS: All animals survived. The weight of the animals increased in all subgroups, but decreased on the 10th day in the subgroups treated with hyperbaric oxygen (p<0.001). The viability of the inferior pole was more evident in animals treated on the 15th day, but did not differ on the 45th day. The growth of the inferior pole has not occurred on the 15th day but on the 45th day after surgery in untreated animals (p<0.01) and treated animals (p<0.05). Vascular and cellular increase in treated animals was significantly higher than in untreated ones. CONCLUSION: Hyperbaric oxygen therapy did not affect the survival of animals but reduced their weight. It improved the viability of the inferior splenic pole, but did not interfere with their growth.

Abstract
BACKGROUND Nonoperative management (NOM) of blunt splenic injuries (BSIs) has been used with increasing frequency in adult patients. There are currently no definitive guidelines established for how long BSI patients should be monitored for failure of NOM after injury. METHODS This study was performed to ascertain the length of inpatient observation needed to capture most failures, and to identify factors associated with failure of NOM. We utilized the National Trauma Data Bank to determine time to failure after BSI. RESULTS During the 5-year study period, 23,532 patients were identified with BSI, of which 2,366 (10% overall) were taken directly to surgery (within 2 hours of arrival). Of 21,166 patients initially managed nonoperatively, 18,506 were successful (79% of all-comers). Patients with isolated BSI are currently monitored approximately 5 days as inpatients. Of patients failing NOM, 95% failed during the first 72 hours, and monitoring 2 additional days saw only 1.5% more failures. Factors influencing success of NOM included computed tomographic injury grade, severity of patient injury, and American College of Surgeons designation of trauma center. Importantly, patients who failed NOM did not seem to have detrimental outcomes when compared with patients with successful NOM. No statistically significant predictive variables could be identified that would help predict patients who would go on to fail NOM. CONCLUSIONS We conclude that at least 80% of BSI can be managed successfully with NOM, and that patients should be monitored as inpatients for failure after BSI for 3 to 5 days.

Abstract
PURPOSE: To assess functional and morphological aspects of spleen auto-implants and of the splenic inferior pole of rats, post-operatively treated or not with hyperbaric oxygen, as well as the survival of these animals, were studied. METHODS: Seventy-eight male Wistar rats, weighing between 192 and 283 g ( 238,3 ± 9,6g), were randomly distributed into three groups: Group1-(n=20), spleen manipulation; group 2-(n=36), spleen auto-implantation; group3-(n= 22), subtotal splenectomy preserving the inferior pole. Each group was subdivided as follows: subgroup a, not submitted to hyperbaric oxygen therapy: 1a(n=10), 2a(n=21), 3a(n= 13); subgroup b, submitted to the therapy: 1b(n=10), 2b(n=15), 3b(n=9). Blood was collected pre-operatively and 11 days after surgery, for the estimation of lipids and immunoglobulins and the counting of platelets and Howell-Jolly corpuscles. The spleen and remains were taken for histological study. RESULTS: The number of surviving animals was significantly higher in groups 1(p<0,01) and 3(p<0,05) relative to those of subgroup 2a. Total cholesterol and the LDL fraction increased significantly in subgroup 2a (p<0,01) and 3a (p<0,05), and remained unaltered in subgroups 2b e 3b. IgM decreased more significantly in subgroup 2 than in subgroup 3 (p<0,001 vs p<0,01). The increase of platelet numbers and the appearance of Howell Jolly corpuscles was smaller in subgroup 2b compared to subgroup 2a , and in group 3 compared to group aqui-> 2. The macro and microscopic appearance in subgroup 2b were more viable than in subgroup 2a, and that of group 3 more viable than in group 2. The survival of the animals carrying their whole spleen or its inferior pole was more frequent than that of the auto-implanted animals. CONCLUSION: Functionality and viability of the whole spleen or of its inferior pole, were better than in the auto-implanted animals. Hyperbaric oxygentherapy contributed to increased survival frequency of auto -implanted animals, and to improve the functionality and viability of the auto-implants and the function of the inferior splenic pole, and did not interfere in animals carrying their whole spleen.

Abstract
PURPOSE Accompanying abdominal injuries are frequent in multiply injured patients and are a common cause of death. A search of the literature was performed focusing on key aspects of initial surgical procedures in abdominal injury. METHODS Literature was searched utilizing PubMed Medline, the Cochrane Central Register of Controlled Clinical Trials, and the German Institute for Medical Documentation and Information (DIMDI) database. The articles were classified according to the level of evidence following the suggestions of the Centre for Evidence Based Medicine. RESULTS Vertical laparotomy should be favored for the initial surgical therapy of abdominal injury. Especially in instable patients, principles of "damage control surgery" should be applied. In case of hollow organ injury, a primary anastomosis should be made whenever possible. A hand suture is most suitable for this. DISCUSSION Non-surgical treatment of blunt abdominal injury is gaining in importance. However, if a surgical intervention is recommended, especially in hemodynamic, instable patients, damage control principles should be favored.

Abstract
PURPOSE: To assess the possibility of preserving the lower pole of the spleen, supplied by the inferior lobar vessels and segmental vessels, or by vessels of the gastrosplenic ligament, in subtotal splenectomy; to study the viability and function of the lower pole of the spleen. METHODS: Thirty-six male Wistar rats were used in this study. Said animals weighed 273-390 g ( 355.2 ± 30.5 g ), and were randomly distributed into three groups. Group 1 comprised ten animals which were submitted to exploratory laparotomy with spleen manipulation (sham operation). Group 2 comprised 16 animals which were submitted to total splenectomy. Group 3 comprised ten animals which were submitted to subtotal splenectomy, preserving the lower pole of the spleen. Blood was collected from all animals before and 90 days after surgery to measure the levels of cholesterol and triglycerides. The animals were sacrificed 90 days after surgery. Spleens and remaining spleens were removed for macroscopic and microscopic examination. RESULTS: Surgery was performed with no complications in all groups. Six animals died in group 2. Spleens of groups 1 and 2, and lower poles of group 3 were macroscopically viable. Apparent white pulp hyperplasia was observed in group 1. In group 3, slight inflammation and capsular fibrosis were observed at the incision site, as well as diffuse hemosiderosis in the red pulp. Average mass of remaining spleen was 35.84% ± 4.31%. No significant difference was observed between preoperative and late postoperative lipid levels in groups 1 and 3 (p > 0.05). Late postoperative lipid levels significantly increased in group 2. CONCLUSIONS: Preservation of the lower pole of the spleen (supplied by gastrosplenic vessels or inferior lobar vessels and segmental vessels) was possible with subtotal splenectomy. The lower pole was macroscopically and microscopically viable in all cases. Subtotal splenectomy preserving the lower pole prevented changes in lipid levels, which were observed in rats submitted to total splenectomy. Plasma lipid levels in rats submitted to subtotal splenectomy were similar to those observed in sham operated rats.

Abstract
OBJETIVO: O estudo foi desenvolvido para avaliar os efeitos do autotransplante esplênico na proteção contra sepse abdominal em ratos Wistar jovens e adultos. MÉTODOS: Foram utilizados 54 ratos Wistar jovens e adultos (90 e 180 dias respectivamente) sendo distribuídos em 3 grupos: Grupo Sham, onde os animais eram submetidos a laparotomia com manipulação de alças apenas (n=6 animais jovens adultos), Grupo Esplenectomia, no qual os animais eram submetidos a esplenectomia total (n=10 animais jovens e adultos) e Grupo Auto-implante, onde os animais eram submetidos a esplenectomia total e um terço do baço era implantado em uma bolsa no retroperitônio (n=10 animais jovens e adultos). Após três meses os animais eram submetidos a nova laparotomia com ligadura e perfuração do ceco para estimular a sepse abdominal e acompanhados até o momento do óbito para estabelecimento de uma curva de mortalidade. RESULTADOS: Houve recuperação do baço implantado em todos os animais. Não houve diferença significativa entre o tempo de óbito entre os grupos. Os animais jovens aparentemente tiveram uma melhor resposta embora não estatisticamente significativa. CONCLUSÃO: Este estudo demonstrou que o auto-implante de baço no retroperitônio não provê proteção efetiva contra sepse abdominal em comparação aos ratos esplenectomizados.

Abstract
INTRODUCTION The spleen is not an essential organ for survival but given its important role in immunologic functions its preservation is justified. OBJECTIVE To analyze our experience with absorbable meshes applied to treat splenic injuries. PATIENTS AND METHOD We performed an ambispective study. From July 1999 to February 2004, 30 patients were treated for traumatic splenic injuries. Ultrasonography and/or spiral computed tomography scanning was carried out for the initial screening evaluation and grading of splenic injuries. The New Injury Severity Score (NISS) was calculated to quantify the severity of trauma. Operative splenic preservation was performed according to established selection criteria. Splenorrhaphy with prosthetic material was accomplished by means of a bag of polyglycolic acid mesh measuring 18 cm yen 23 cm (Dexon mesh) that was hand tailored and wrapped around the entire surface of the spleen. RESULTS Thirty patients with splenic traumatic injuries were treated. The mean age was 36.2 +/- 16.6 years. Twenty-three patients (76.6%) required splenectomy, nonoperative management was achieved in 1 patient (3.3%), and splenorrhaphy with prosthetic material was carried out in 6 patients (20%). Grade III injuries were present in 13 patients (43.3%), grade IV in 13 patients (43.3%), and grade V in 4 patients (13.3%). The mean NISS was 18.9 +/- 9.1. No significant differences were detected between the two groups (splenectomy or mesh splenorrhaphy) in NISS (p=.53) or grade of splenic injuries (p=.69). Morbidity was related to the presence of multiple injuries (p=.002) and was greater in the group with mesh splenorrhaphy (p=.002); however, there were no septic complications in this group. A positive correlation was observed between the length of hospital stay and NISS (p=.01). The length of hospital stay was also significantly associated with the presence of multiple injuries (p=.005) and with morbidity (p=.0002), but was not associated with the type of surgery carried out (p=.17). No complications were observed during follow-up (median of 28 months) in patients who underwent splenic salvage procedures. CONCLUSIONS Mesh splenorrhaphy is a suitable therapeutic option for patients with severe trauma, grade IV splenic injuries, or delayed rupture of the spleen. Both morbidity and length of hospital stay were associated with the presence of multiple injuries rather than with the type of surgery carried out. The safety, effectiveness and absence of septic complications related to the use of prosthetic material in splenic trauma salvage surgery were notable.

Abstract
OBJETIVO: A morbimortalidade do tratamento conservador do baço após trauma desse órgão depende da extensão da lesão e da experiência da equipe cirúrgica com trauma esplênico. O objetivo deste trabalho é avaliar experimentalmente a recuperação esplênica após lesão cortante tratada conservadoramente. MÉTODO: Foram utilizados 20 cães machos, mestiços, com peso variando entre 7kg e 12kg. Sob anestesia com pentabarbitúrico sódico endovenoso, provocou-se uma lesão cortante longitudinal no baço, em uma extensão de 5 cm e profundidade de 3 cm. Em seguida, os animais foram distribuídos aleatoriamente, de acordo com a conduta com a ferida esplênica, em três grupos: Grupo 1 (n=10) - sem reparo cirúrgico; Grupo 2 (n=5) - sutura esplênica contínua com fio de categute cromado 5-0; Grupo 3 (n=5) - introdução de um segmento de omento maior na ferida esplênica e sutura contínua do baço com o omento, utilizando fio categute cromado 5-0. Os cães foram acompanhados durante cinco (Grupo 1A) ou 28 (Grupo 1B, 2 e 3) dias. RESULTADOS: Todos os animais sobreviveram ao pós-operatório e não foram percebidas adversidades decorrentes da operação durante esse período. Não foi encontrada diferença no aspecto macroscópico dos baços retirados de todos os grupos. À microscopia, percebeu-se fragmento de omento dentro da cicatriz esplênica nos animais do Grupo 3. CONCLUSÕES: A lesão cortante de baço canino pode ser tratada pelos métodos conservadores. Caso se opte pelo tratamento cirúrgico, a sutura com e sem auxílio do omento são eficazes.

Abstract
OBJETIVO: Avaliar as repercussões clínicas e laboratoriais em pacientes submetidos a auto-implantes esplênicos. MÉTODOS: Foram estudados 29 pacientes com lesões graves do baço, 20 que receberam auto-implantes esplênicos (grupo I), nove a esplenectomia total sem preservação de tecido esplênico (grupo II) e 22 pacientes com baços íntegros constituíram o grupo controle (grupo III). Investigaram-se as complicações pós-operatórias imediatas e tardias. No pós-operatório tardio realizaram-se exames hematológicos (hematimetria, hemoglobina, hematócrito, plaquetas, leucócitos globais e segmentados, linfócitos e corpúsculos de Howell Jolly). Dosaram-se as imunoglobulinas (IgA, IgM e IgG) e linfócitos T totais (LTT), linfócitos T ativos (LTA) e linfócitos B. Realizou-se cintilografia esplênica com enxofre coloidal marcado com o 99mTc. RESULTADOS: Em nenhum dos grupos verificou-se leucocitose ou trombocitose. Os corpúsculos de Howell-Jolly foram observados no grupo II e neste grupo a IgM esteve reduzida. A cintilografia mostrou tecido esplênico captante no grupo I. CONCLUSÃO: O auto-implante é uma boa alternativa quando a esplenectomia total for necessária.

Abstract
Um aumento da susceptibilidade à infecção severa é uma complicação reconhecida da esplenectomia. Um grande número de alternativas tem sido propostas que poderiam impedir esta complicação do estado asplênico. O presente estudo analisa a regeneração histológica do tecido esplênico em ratos submetidos a esplenectomia subtotal. Foram utilizados trinta ratos machos da linhagem Wistar, adultos, pesando entre 160 e 210g. Os animais foram submetidos a esplenectomia subtotal e divididos em três grupos contendo dez ratos cada onde foram estudados após 15, 30 e 45 dias. Após este período de observação o tecido esplênico foi recuperado e submetido a exame histológico. A estrutura tecidual esplênica no 15º dia se apresentava irregular, porém sem necrose. Após 30 dias , a cápsula se apresentava histologicamente espessada e com maior desenvolvimento. Em 45 dias foi observado semelhança considerável entre o tecido esplênico remanescente e o baço normal. O presente estudo mostra que o baço submetido a esplenectomia subtotal se regenera completamente em um período de 45 dias.

Abstract
A consecutive series of 11 patients with an acute blunt splenic injury were treated with a 'safe resection' technique. 57% of the injured spleens (range 35-100%) were saved. None of the patients had any signs of secondary bleeding in control CT scan and the mortality was zero. No second-look laparotomies were performed. Follow-up time was at least two months (range 2 month-6 yr). Operation time was in average 120 min. Total mean peroperative bleeding was 1400 ml. Partial resection may offer patient a change for normal function of the injured spleen. However, it is not yet known what is the critical mass of spleen tissue needed for humans. The follow-up time of the present study is still too short to estimate this fact, but further studies may show the benefit of the present method in avoiding serious long term immunological complications of splenectomy. This present study introduces a novel technique for partial resection of injured spleen. Operation can be performed safely and quickly with a complication risk comparable to splenectomy. Resection is applicable even for multi-trauma patients.

Abstract
STUDY AIM The aim of this retrospective study is to report five cases of laparoscopic splenorraphy with an absorbable perisplenic mesh for splenic injury. PATIENTS AND METHOD From January 1996 to February 1998, three men and two women (mean age: 52 years) were included in this study. The splenic lesions were due to either a fall (n = 3), a traffic accident (n = 1), or pleural paracenthesis in a patient with mediastinitis after valvular replacement. Splenic injury was recognized by ultrasonography. The patients were operated as either emergency cases (n = 2), or within 24 hours (n = 3). The procedure included evacuation of the hemoperitineum, total liberation of the spleen, and splenic hemostasis with a perisplenic mesh which was used in open surgery. The mesh placed behind the spleen, covering its superior and inferior poles, was unrolled forwards and burses progressively tightened. RESULTS There was no conversion, no mortality, no morbidity. In the four injured patients, the mean duration of surgery was 120 minutes (70-180), without any blood transfusion, and the patients were discharged on d4 or 5. The fifth patient, after valvular replacement, was operated on with anticoagulation. The mean duration of surgery was 270 minutes. Four blood units were necessary. He was discharged at d26. CONCLUSION This technique combines the advantages of the perisplenic mesh which is efficient and safe, with the advantages of laparoscopic surgery which simplifies the postoperative course. It can only be used in case of isolated splenic injury in patients with stable hemodynamic condition.

Abstract
OBJECTIVE The spleen is an organ of the defense system with important roles in filtering functions, phagocytosis, and immunoglobulin production. Septic phenomena are severe complications that may occur after total splenectomy. To avoid these adverse effects, the preservation of the spleen is indicated. However, in the presence of severe spleen damage, lesions of the splenic pedicle, or both, complete removal of the spleen has been considered unavoidable. METHODS The present paper presents the preservation of the upper splenic pole supplied by the splenogastric vessels in six patients with severe injuries of the spleen and its pedicle. RESULTS All patients had good postoperative courses. CONCLUSIONS Subtotal splenectomy may be useful in the treatment of severe injuries of the distal part of the spleen, when the vessels of its pedicle are damaged, or both.

Abstract
Based upon the anatomicosurgical segments of the spleen, suggested by DiDio and demonstrated in cadavers, classified and named by Neder (1958) and Zappalá (1958, 1959, 1963), the normal segmental organization was anatomically and radiologically confirmed in 51 human spleens, after studying corrosion casts and radiograms of intraparenchymal vessels (Christo, 1959 a, b, 1960, 1962, 1963, 1993). From 1958 to 1965, pioneer segmental resections were performed successfully in 34 dogs and in 9 patients to safely remove traumatic injured splenic segments. At the same time, the overwhelming postsplenectomy infection (OPSI) became well identified. Consequently, to save normally functioning splenic parenchyma became the most important issue in the management of splenic injuries. The anatomical basis for partial splenectomy and splenic segmentectomy is discussed. The term "splenorrhaphy" was employed to designate all conservative or parenchyma saving operations of spleen based upon its vascular supply: from topical packings to splenic sutures including "cappings" and partial splenectomies. From analysis of 38 consecutive reports in 20 years, covering 4,076 patients, it was concluded that "splenorrhaphies" had been electively employed in 46% of the injuries and partial splenectomies were identified in 8.6% of these surgical interventions. However, the critical minimal mass of splenic tissue to be preserved after partial splenectomies is still to be defined. Postoperative complications directly related to "splenorrhaphies" are rare. Uncommonly performed after splenectomies, the heterotopical splenic autotransplantation has presented dubious results. Trials with nonoperative management of splenic blunt trauma injuries have been safer among children, whose spleens are predominantly transversally disrupted and have a higher relationship "capsular resistance/parenchymal bulk". Splenectomies have been most frequently the ultimate result of delayed laparotomy and underlying risks of growing blood requirements may surpass the advantages of preventing OPSI.

Abstract
From January 1984 to June 1992, a period of 8.5 years, 60 patients with splenic trauma were treated in Lacor Hospital. the spleen trauma was managed conservatively in 47 (78%) of the patients. Of these, 36 of the patients (60%) were not operated upon. Eleven (18%) were operated upon but nine (15%) patients had exploratory laparotomy only without spleen manipulation and in two (3%) splenic repair was performed. Thirteen (22%) patients had splenectomy. In the non-operative group, recurrent or rebleeding was detected in one patient (2%) and delayed bleeding occurred in five patients (8%). Overall mortality rate was five (8%); two (3%) occurring in splenic salvage and three (5%) in splenectomized patients. It is concluded that with availability of facilities and personnel, in selected cases of blunt splenic trauma, splenic conservation is safe but requires close monitoring.

Abstract
OBJECTIVE The authors reviewed their experience with life-threatening blunt injuries in approximately 2900 children (0-14 years) admitted to the designated state pediatric shock trauma unit between 1990 and 1993. METHODS During this time, the authors treated all severely injured children with a prospective, nonoperative protocol if they were hemodynamically stable after less than 40 mL/kg fluid replacement, had proven evidence of solid organ injuries and remained stable in the pediatric intensive care unit under surgical management. RESULTS Twenty-eight children had computed tomography (CT) or operatively proven lacerations of the spleen, 25 had lacerations of the liver, 18 had lacerations of the kidney, 7 had lacerations of the pancreas, and 11 had two or more solid organ injuries. Three of the 28 children with injured spleens required laparotomy (two splenectomy, one splenorrhaphy). Two of the 25 children with liver injuries required laparotomy (one suturing, one partial resection). One of the 18 children with kidney injuries required laparotomy (nephrectomy), and 3 of the 7 children with pancreas injuries required laparotomy (two resection, one pseudocyst). There were three deaths after laparotomy (two head, one chest/abdominal). There were no deaths in the children managed nonoperatively, and there were no immediate or long-range complications. CONCLUSIONS Comparison of the authors' data with the National Pediatric Trauma Registry shows similar results. The authors believe that nonoperative management of solid organ injuries under careful surgical observation in a pediatric intensive care unit is safe and appropriate.

Abstract
A fabric constructed of biodegradable mesh was used in the operative repair of injured intra-abdominal organs in 60 patients at two Level I Trauma Centres. Splenorrhaphy was performed in 44 patients, hepatorrhaphy in eight, renorrhaphy in five and one combined repair of spleen and liver and one kidney and liver. The age range for the patients was 5 to 61 years. Multiple-organ injury occurred in 21 patients. Mean emergency room systolic BP for the patient series was 120 +/- 24 mmHg (SD), Glasgow Coma Scale 14.3 +/- 1.9, haematocrit 37.2 +/- 6.4 per cent, Injury Severity Score (ISS) 28.1 +/- 16.3, Abdominal Trauma Index (ATI) 15.5 +/- 7.5. Postoperative complications occurred in 36.7 per cent of patients. Time for the operation averaged 165.1 + 72.1 min and preoperative and operative transfusion volume averaged 2248 ml. There were three deaths (5.4 per cent). The mesh organ repair technique is an alternative to conventional surgical procedures used to control bleeding from injured organ surfaces and to close organ parenchymal defects.

Abstract
Seventy-five adults with splenic injury were evaluated prospectively over 45 months to examine the possibility of splenic preservation. Haemodynamically unstable patients underwent surgery with the intent of splenic preservation. Stable patients received non-operative treatment regardless of the grade of splenic injury determined by ultrasonography and computed tomography. Thirty-seven patients required splenectomy and in 38 the organ was preserved (20 operative preservation, 18 non-operative treatment). Of 22 patients initially receiving non-operative treatment, there were four secondary haemorrhages after 7, 7, 10 and 13 days making surgery necessary. Three of these patients underwent splenectomy and in one the spleen was preserved by partial resection. After splenectomy four patients required reoperation because of rebleeding or for evacuation of a haematoma. Patients who had undergone splenectomy had a significantly increased infection rate (P < 0.005) compared with those in whom the spleen was preserved, even when patients were matched with respect to multiple trauma using the Injury Severity Score (P < 0.01).

Abstract
Forty-nine adults underwent surgery for splenic injury: 17 (group 1) had salvage with a splenic mesh, seven (group 2) underwent other preservation techniques, and 25 (group 3) underwent splenectomy. There were six, zero and 11 hilar lesions in groups 1, 2 and 3, respectively. Seven of 15 associated lesions involved the digestive tract. There was no significant difference in transfusion requirements, length of operation or postoperative complications. One patient died in each of groups 1 and 2, and eight in group 3. Secondary splenectomy was performed once in groups 1 and 2. The duration of hospital stay was shorter in the preservation groups (1 and 2) than in group 3. Splenic preservation was feasible in 24 of 49 adults with splenic injury requiring surgery. The splenic mesh wrap is safe and reliable, and allows splenic salvage even with hilar injury.

Abstract
Because of the ready availability of autotransfusers and risk of transfusion-transmitted disease, the authors reexamined the management of splenic trauma. During the past 6 months, 20 adult and pediatric patients were treated for blunt splenic trauma. Nine had "minor" lacerations and were successfully managed nonoperatively. Eleven had ongoing hemorrhage or associated visceral injury necessitating laparotomy. In two, coexistent injuries were life threatening and total splenectomy was performed. The other nine had major splenic trauma that was either an isolated phenomenon or was associated with an injury not jeopardizing survival; eight spleens were salvaged. Mean intra-abdominal blood loss was approximately 1250 mL and, using a "cell saver," an average of approximately 790 mL was reinfused. Six received no other blood transfusion whereas three received 2250 mL homologous blood in addition to 4250 mL via the "cell-saver." With hilar laceration, repair was facilitated by temporarily occluding the splenic pedicle atraumatically, and suturing torn polar branches via the laceration site. In both children and adults with major splenic injury, the authors now recommend early laparotomy with reinfusion of autologous blood. The spleen or a large remnant can usually be salvaged, and homologous blood transfusion with its attendant complication can often be obviated altogether.

Abstract
This article examines the current management of trauma to the spleen. The incidence, mechanism, classification, diagnosis, treatment and complications of splenic trauma are reviewed. Modern radiological investigations are assessed in view of the recent vogue for non-operative management. The effects of splenectomy and particularly of overwhelming postsplenectomy sepsis are discussed. The role of non-operative management of splenic injuries in children and in adults without associated injuries is emphasized. Means of repairing and preserving the spleen are detailed. Prompt splenectomy is necessary in seriously traumatized patients, especially those with head or multiple injuries.

Abstract
Splenic salvage has been undertaken increasingly in the past decade. The optimal method is not determined in adults. Sixty-seven consecutive cases of splenic injury were reviewed during a time of change in management policy. Splenic salvage rose from 10% of cases in 1980-83 to 57% in 1984-88. Treatment by observation resulted in 46% of patients undergoing delayed laparotomy. Injury to other intra-abdominal organs required laparotomy in 23% of patients with multiple injuries. Operative splenic salvage in the adult is feasible and may result in a higher rate of splenic salvage.

Abstract
The modern era for splenic surgery for injury began in 1892 when Riegner reported a splenectomy in a 14-year-old construction worker who fell from a height and presented with abdominal pain, distension, tachycardia, and oliguria. This report set the stage for routine splenectomy, which was performed for all splenic injury in the next two generations. Despite early reports by Pearce and by Morris and Bullock that splenectomy in animals caused impaired defenses against infection, little challenge to routine splenectomy was made until King and Schumacker in 1952 reported a syndrome of "overwhelming postsplenectomy infection" (OPSI). Many studies have since demonstrated the importance of the spleen in preventing infections, particularly from the encapsulated organisms. Overwhelming postsplenectomy infection occurs in about 0.6% of children and 0.3% of adults. Intraoperative splenic salvage has become more popular and can be achieved safely in most patients by delivering the spleen with the pancreas to the incision, carefully repairing the spleen under direct vision, and using the many adjuncts to suture repair, including hemostatic agents and splenic wrapping. Intraoperative splenic salvage is not indicated in patients actively bleeding from other organs or in the presence of alcoholic cirrhosis. The role of splenic replantation in those patients requiring operative splenectomy needs further study but may provide significant long-term splenic function. Although nonoperative splenic salvage was first suggested more than 100 years ago by Billroth, this modality did not become popular in children until the 1960s or in adults until the latter 1980s. Patients with intrasplenic hematomas or with splenic fractures that do not extend to the hilum as judged by computed tomography usually can be observed successfully without operative intervention and without blood transfusion. Nonoperative splenic salvage is less likely with fractures that involve the splenic hilum and with the severely shattered spleen; these patients usually are treated best by early operative intervention. Following splenectomy for injury, polyvalent pneumococcal vaccine decreases the likelihood of OPSI and should be used routinely. The role of prophylactic penicillin is uncertain but the use of antibiotics for minor infectious problems is indicated after splenectomy.

Abstract
Splenic salvage following blunt injury can fail when parenchymal bleeding is uncontrollable. To define the usefulness of an argon beam coagulator for hemostasis, we used the instrument in a laboratory trial of partial splenic resection. New Zealand white rabbits, weighing 4 to 5 kg, had sharp excision of the lower half of the spleen. No sutures were used to control hemorrhage from the cut splenic surface or the hilar vessels. Hemostasis was achieved with 2 to 4 seconds of electrocoagulation delivered by a beam of argon gas. All animals survived the procedure and were in good health when killed between the fourth and sixth week following the procedure. At necropsy, the spleen was viable in all animals with no abscess or hematoma. Minimal adhesions from the treated splenic surface to the omentum were found. The scar at the cut surface was 1 mm in depth, and the histology of the remainder of the spleen was normal. In this simulated splenic injury model, argon beam coagulation was uniformly successful in achieving hemostasis. Minimal tissue destruction and lack of infection were noted. The argon beam coagulator may be useful in patients with severe splenic injuries and other situations requiring partial splenectomy.

Abstract
In an effort to reduce the rate of nontherapeutic celiotomy yet avoid the possibility of missed injuries, surgeons are evaluating protocols for nonoperative management of abdominal trauma. Discussion of this controversial issue includes specific approaches to the diagnosis and management of splenic injury, gunshot wounds, and stab wounds.

Abstract
Control of massive hemorrhage from intra-abdominal organs and major vascular structures may tax the ingenuity of the trauma surgeon. It is emphasized, however, that total blood loss and the amount of transfused blood are far less critical than the duration and severity of shock.

Abstract
During the past decade splenic salvage procedures rather than splenectomy have been considered the preferred treatment for traumatic splenic injuries. Splenic preservation has been most often accomplished by splenorrhaphy and more recently by a controversial nonoperative approach. This report delineates indications, contraindications, and results with splenectomy, splenorrhaphy, and nonoperative treatment based on an 11-year experience (1978 to 1989) in which 193 consecutive adult patients with splenic injuries were treated. One hundred sixty-seven patients (86.5%) underwent urgent operation. Of these, 111 (66%) were treated by splenorrhaphy or partial splenectomy and 56 (34%) were treated by splenectomy. During the last 4 years, 26 additional patients (13.5%) were managed without operation. Patients considered for nonoperative treatment were alert, hemodynamically stable with computed tomographic evidence of isolated grades I to III splenic injuries. Overall 24% of the injuries resulted from penetrating trauma, whereas 76% of the patients sustained blunt injuries. Complications were rare, with two patients in the splenorrhaphy group experiencing re-bleeding (1.8%) and one patient (4%) failing nonoperative treatment. The mortality rate for the entire group was 4%. This report documents that splenorrhaphy can safely be performed in 65% to 75% of splenic injuries. Splenectomy is indicated for more extensive injuries or when patients are hemodynamically unstable in the presence of life-threatening injuries. Nonoperative therapy can be accomplished safely in a small select group (15% to 20%), with a success rate of nearly 90% if strict criteria for selection are met.

Abstract
From 1980 to 1989, 240 adult patients underwent splenorrhaphy at one urban trauma center. This represents 43.4% of all splenic injuries seen during this time interval. Splenic injuries were graded I to V, and splenorrhaphy was attempted except when the spleen was shattered or when multiple injuries with associated hypotension were present. Penetrating wounds, blunt trauma, or iatrogenic/unknown etiologies were present in 54.2%, 41.6%, and 4.2% of patients, respectively. Grade I or II injuries were present in 51.7% of patients, grade III in 34.6%, grade IV or V in 9.6%, and unknown grade in 4.1%. The technique of splenorrhaphy was simple suture (usually chromic) with or without the addition of topical hemostatic agents in 200 patients (83.3%), topical agents alone in 12 (5%), unknown type of repair in 12 (5%), compression, cautery, or nonbleeding injury in 9 (3.8%), and partial or hemisplenectomy in 7 (2.9%). Postoperative rebleeding occurred in three patients (1.3%) with grade II, III, and IV injuries, respectively, and led to splenectomy at reoperation. In another patient who had a hemisplenectomy performed for a grade IV injury, subphrenic abscesses and septic shock led to the death of the patient. Splenorrhaphy can be safely performed in properly selected adult patients after a variety of injuries. The risk of rebleeding is practically nil when the spleen is fully mobilized and visualized during repair.

Abstract
We reviewed 37 consecutive, hemodynamically stable patients (16 adults, 21 children) who had splenic injuries diagnosed by computed tomography (CT) scan to compare the CT evaluation with operative assessment of injury and eventual treatment. Computed tomographic scans and operative findings were graded by a splenic injury scoring system. Two patients were classified as having grade 1, 21 as grade 2, 11 as grade 3, and 3 as grade 4 splenic injuries. Computed tomography underestimated the degree of injury in 9 of 17 (53%) operated patients (mean CT score, 2.6; mean operative score, 3.3; p less than 0.01). Six of sixteen adults and 19 of 21 children were intentionally treated by observation. There were 5 treatments failures (20%), 3 due to bleeding and 1 each due to pancreatic injury and splenic abscess. The failure rate of observation was lower in children (16%) than in adults (33%), even though children had a higher Splenic Injury Score (2.4 versus 1.8). Patients who underwent an operation received twice as much blood as the observed group. There was no significant difference in Injury Severity Score or total fluid requirements between operated and observed patients. Operations increased in frequency in both adults and children as the injury score increased. This experience suggests that CT scan accurately determines the presence of splenic injury but commonly underestimates its severity. While children with grades 1 through 3 injuries are likely to be treated successfully with observation, adults who have more minor splenic injuries often fail observation and may be treated better by prompt operation.

Abstract
From July 1983 through December 1987, 300 consecutive patients with penetrating gunshot wounds of the abdomen causing visceral or vascular injuries were treated. Resuscitative thoracotomy was required in 20 patients (6.6%), and only two survived. The most commonly injured organs were the small bowel (60%), colon (41.6%), liver (29.3%), vascular structures (24.6%), stomach (17.3%), and kidney (17.0%). The overall survival rate for the series was 88.3%; however, if only the 226 patients without vascular injuries are considered, the survival rate was 97.3%. In the 35 patients who died, the blood pressure on admission was 51 mmHg, 18 required a resuscitative thoracotomy, four visceral or vascular injuries were present, and the median blood replacement was 18 units. The cause of death was perioperative shock in 30 patients (85.7%), whereas five patients (14.3%) died of sepsis and multiple organ failure. The most common postoperative complication in survivors and patients who died later in the study was an intra-abdominal abscess (3.0%). Rapid conservative operative techniques for civilian gunshot wounds leads to few postoperative complications and an excellent survival rate, especially if vascular injuries are not present.

Abstract
Although the preservation of splenic tissue may prevent overwhelming infection after splenectomy, the degree of protection conferred by small remnants has not been optimal. We investigated whether either splenic reticuloendothelial clearance of a blood flow-dependent colloid or macrophage and T-cell populations might be altered by resection or autotransplantation of the spleen. Our results have shown that bloodstream reticuloendothelial clearance of technetium 99m sulfur colloid is not impaired by splenectomy, partial resection of the spleen, or splenic autotransplantation. Such clearance is dependent on spleen weight and is not related to differences in either macrophage or helper or suppressor T-cell populations. This suggests that autotransplantation of the spleen is inferior to preservation of even a small hilar remnant and implies that repair or partial resection of the spleen will provide greater protection than autotransplantation.

Abstract
Overwhelming infection after splenectomy remains a problem despite the introduction of vaccine and antimicrobial prophylaxis. To evaluate prospectively various procedures proposed for salvage of the spleen, we measured reticuloendothelial function for two to five years in 51 patients who had initially presented with abdominal trauma and suspected splenic rupture. The mean percentage of pocked erythrocytes and the clearance of antibody-coated autologous erythrocytes in 8 patients who had splenic repair and in 6 who had partial splenectomy were the same as in 11 controls with intraabdominal injury that did not involve the spleen. The mean percentage of pocked erythrocytes remained significantly elevated in 19 patients who had undergone total splenectomy without autotransplantation of splenic tissue. One of seven patients who underwent splenic autotransplantation had a normal level of pocked erythrocytes 18 months after surgery, and a second patient had only a slight elevation at 24 months. The mean (+/- SEM) half-time clearance of labeled erythrocytes was significantly longer in the group that had total splenectomy without autotransplantation (421.1 +/- 74.5 hours) than in the autotransplantation group (91.6 +/- 20.0) or in the controls (5.4 +/- 2.0). We conclude that reticuloendothelial function was better preserved after partial splenectomy and splenic repair than after splenic autotransplantation, but that autotransplantation was superior to total splenectomy and appeared to be safe. Splenic autotransplantation deserves further study in patients who have had splenic trauma when other surgical maneuvers to save the spleen are not possible.

Abstract
During the past decade, one of the most controversial issues in the surgical literature has been the question of what is the most appropriate management of splenic trauma. An increased understanding of the physiologic importance of splenic function must now be weighed against the life-threatening risk of exsanguinating splenic hemorrhage. In this article, postsplenectomy sepsis and mortality in adults and the selective management of blunt splenic trauma are discussed. Although the risks of postsplenectomy sepsis and serious infection are low, they do exist. A policy of individual assessment of cases is recommended when the merits of splenectomy versus those of splenic preservation are considered. Similarly, in cases of blunt splenic trauma, a policy of individual assessment is not only intellectually attractive but also safe, rational, and effective from a clinical standpoint. In selected cases of blunt splenic trauma, nonoperative management and splenorrhaphy are acceptable alternatives; however, in many instances splenectomy remains the most appropriate and only course of action.
