Abstract
Adequate hemostasis during surgical procedures is essential for successful patient outcomes and reduced healthcare resource utilization. Topical hemostatic agents can act as catalysts for the clotting cascade or as a scaffold to promote platelet activation or aggregation. Although an ever-increasing number of topical absorbable hemostatic agents are now available for perioperative use, health care providers are disadvantaged by the lack of comparative data on feasibility, clinical effectiveness, advantages, and limitations of each in specific surgical settings. This knowledge is important for appropriate product choice when patient characteristics, type of surgical procedure, type of bleeding, and product availability may differ widely. This manuscript provides the first comprehensive overview of Avitene™ Microfibrillar Collagen Hemostat (MCH), a bovine collagen-based absorbable hemostat that has been widely used for over four decades in the United States and abroad. MCH is indicated as an adjunct to hemostasis across a broad spectrum of surgical specialties and has been shown to achieve hemostasis with positive patient outcomes and a favorable safety profile in many applications, including hepatic, orthopedic, splenic, oral, and otolaryngologic surgery. Although published clinical data regarding the use of MCH in cardiovascular surgery is limited, evidence suggests moderate use in this specialty. The information contained in this systematic review will help health care providers understand the clinical use and effectiveness of the product to determine appropriate use in differing bleeding scenarios across multiple surgical specialties. Future studies may include comparative functional and cost analyses to explore the economic advantages of using absorbable hemostatic agents compared with each other or with conventional techniques of hemostasis, when appropriate.

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
The relatively recent recognition of the immunological consequences of splenectomy in both children and adults, coupled with an increased use of noninvasive methods of detecting splenic injuries, has resulted in the development of a nonoperative approach to selected patients with blunt splenic trauma. Currently, nonoperative management of pediatric splenic injuries is the treatment of choice, with success rates greater than 90%. Due to the increased severity of injury in adult trauma patients, this method of treatment is applicable in only 50% of older patients with mild to moderate splenic trauma. As experience with nonoperative treatment has accumulated, the need for large blood transfusions, missed intestinal injuries, and delayed splenic rupture have been found to be uncommon events. However, patients selected for nonoperative management must be monitored in a setting where the treating surgeon is readily available for both serial examinations and operative intervention should nonoperative management fail.

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
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
The aim of this study was to assess a newly developed computerized tomography (CT)-based splenic injury index in predicting the outcome of splenic injury. Twelve patients with isolated splenic injuries were studied. Splenic parenchymal injury was graded from 1 to 4 based on CT. The splenic injury index was obtained by multiplying the parenchymal score by the volume haemoperitoneum, which was measured on the CT scanner. The 12 patients with CT-proven splenic injuries had a mean injury index of 193.5 +/- 191 (mean +/- s.d.). The 3 patients who failed conservative management had a mean index of 475 +/- 50, compared with an index of 99.5 +/- 100 in the nine managed non-operatively (P less than 0.001). This new CT-based splenic injury index allows morphological assessment of splenic injury and may predict the outcome of splenic trauma.

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
The use of a nasogastric tube to empty the stomach contents prevents compression of the splenic parenchyma and allows clear visualization of the anterior medial border of the spleen and perisplenic area. Unsuspected superficial lacerations or a contained hematoma by the splenic capsule may become apparent only following this procedure. A representative case is reported. Routine application of this simple procedure aids avoiding occasional pitfalls and helps in early diagnosis of splenic injury at the time of a CT study.

Abstract
One hundred and forty-seven patients with splenic injury admitted to 18 different hospitals were included in a prospective multicentre study. The spleen was saved in 64 per cent. Out of the total series, 43 per cent of patients were not operated upon, 5 per cent had exploratory laparotomy only, and in 16 per cent splenic repair was performed. Treatment is discussed with reference to the nature of the splenic lesion, concomitant injuries, amount of blood transfusion given, and age of the patient. No deaths were definitely related to the splenic injury. The frequency of serious recurrent bleeding was not higher in the splenic salvage group when compared with the splenectomy group. Delayed bleeding was detected in 4 per cent of the patients. The mode of treatment varied considerably in different hospitals in that conservative treatment was performed in 14, splenic repair in 10 and splenectomy in 12 hospitals. Splenic salvage seems safe in most patients with a splenic injury. However, meticulous surveillance of the patient is mandatory.

Abstract
Splenectomy produces significant immediate and long-term risks for the patient, and there is general agreement that it should be reserved for clear-cut unavoidable indications. However, accidental injury to the spleen in the course of another operation (incidental splenectomy,) accounts for almost 40% of splenectomies in some series. Incidental splenectomy is most likely to occur in left upper quadrant operations such as proximal gastric vagotomy, or in colonic operations involving mobilization of the splenic flexure. Incidental splenectomy rates of between 2% and 9% have been reported in association with these procedures. The results of an operative strategy of specific protection of the spleen as the first step in a left upper quadrant operation ('defusing' the spleen) are reported. It was not necessary to remove the spleen because of accidental injury in 417 consecutive operations over a 5 year period after implementation of this policy. There were several minor splenic capsular tears which were controlled by intraoperative haemostatic measures. There were no cases of postoperative splenic bleeding. 'Defusing' the spleen is an effective step in preventing splenic injury in left upper quadrant operations.

Abstract
In a retrospective survey of splenic trauma managed at a teaching hospital, the data of 127 patients during a 2 year period have been analysed. Splenic conservation was achieved in 47 laparotomies (38.8 per cent). Six patients with blunt abdominal trauma (4.7 per cent of all patients) were managed non-operatively. Splenic conservation by suture with or without packing with omentum or oxidized cellulose was successful in 27 out of 37 attempts. Failure of this technique was easily recognized during laparotomy and no patient required re-operation for continued splenic bleeding after splenorrhaphy. There was no significant difference between successful conservation of the spleen at laparotomy of patients below the median age (28 years) and older patients. Wound sepsis was increased after splenectomy (P less than 0.05). Splenic conservation is not appropriate for all types of splenic injury. Where conservation is not possible splenectomy and re-implantation is recommended.

Abstract
In this series of 80 consecutive patients with injured spleens scintigraphy was the diagnostic mainstay and was performed in 63 patients. Fifty-five patients were initially managed without operation. Two of them, however, underwent laparotomy respectively 1 and 2 days after admission because of increasing symptoms and signs. Twenty-seven patients underwent laparotomy, with successful conservative surgery in 8 and splenectomy in 19. However, in at least five of these it was thought in retrospect that repair of the spleen might have been possible. There were no deaths or serious morbidity from the injury to the spleen. It is concluded that no operation or operative repair of the spleen is the treatment of choice in the majority of patients with blunt injuries. In order to avoid loss of life as well as loss of the spleen, strict adherence to an aggressive, exact diagnostic process, using non-invasive diagnostic imaging and close clinical observation, as well as experienced, painstaking surgical techniques, is necessary.

Abstract
This review was undertaken to analyze critically the complications resulting from operative splenic salvage. Over a 6 year period, 200 adults who sustained splenic trauma underwent laparotomy. The mechanism of injury was blunt in 138 patients (69 percent), a stab wound in 32 patients (16 percent), and a gunshot wound in 30 patients (15 percent). Splenorrhaphy was accomplished in 85 patients (42 percent). Methods of repair included cautery and hemostatic agents in 24 patients (28 percent), debridement and suturing in 42 patients (50 percent), and partial resection in 19 patients (22 percent). Six patients died, four from head trauma and two from multiple organ failure. Postoperative complications occurred in 14 patients. Four were intraabdominal. Three patients required reoperation for splenic hemorrhage; one (2 percent) after suture repair and two (11 percent) after partial resection. A left subphrenic abscess developed in another patient. Splenic reimplantation was performed in 43 patients (22 percent). Five deaths occurred. One was due to head trauma, three to multiple organ failure, and one to overwhelming pneumococcal infection. Eleven postoperative complications occurred, but none was related to splenic autotransplantation. Despite the enthusiasm for splenic salvage, the number of patients suitable for splenorrhaphy plateaued at 56 percent. Complications of splenorrhaphy are infrequent, and the risk increases with more complex salvage attempts. We believe that splenic reimplantation remains a safe procedure.

Abstract
Splenectomy results in a lifelong risk of overwhelming infection in the adult as well as the child. This has prompted our current enthusiasm for splenic salvage in trauma patients. A number of alternatives to total splenectomy exist; however, the complications that result from splenic salvage must not exceed the risk incurred by loss of this organ. Splenorraphy can be performed safely in the majority of patients despite associated intraabdominal injuries. When splenectomy is necessary, reimplantation of splenic tissue is feasible. The efficacy of this technique is preventing postsplenectomy sepsis remains to be established.
