Assessment of nonoperative management of blunt spleen and liver trauma

An 8-year analysis of nonoperative management (NOM) of spleen and liver trauma was done in a level 1 trauma center. Spleen and liver trauma was diagnosed in 279 patients: 93 children (<18), 137 younger adults (18-54), and 49 older adults (> or = 55). Nineteen patients who failed resuscitations died within 0-60 minutes of arrival and were excluded from treatment analysis. Operative management (OM) was done in 39 (15%) and NOM in 221 (85%) patients with failure (NOMF) in 11 (5%). NOM and NOMF was 82 per cent and 5.6 per cent in spleen, 74 per cent and 14.3 per cent in combined spleen/liver, and 96 per cent and 1.5 per cent in liver trauma (P value <0.001). NOM was done in 99 per cent of children, 81 per cent of younger adults, and 68 per cent of older adults with 0 per cent, 8 per cent, and 10 per cent NOMF. Higher grades of splenic trauma and CT fluid had higher OM rate. NOM success rates were 93.8 per cent in grade 3 and 90.3 per cent in higher grades of spleen trauma. There was no NOMF in higher grades of liver trauma. CT fluid grade had no impact on NOMF. Female patients had higher mean injury severity score, age, and mortality compared to cohorts. NOM should be attempted in hemodynamically stable patients. Age over 55, higher grades of injury, and large hemoperitoneum were not predictors of failure of NOM.     

The importance of nonoperative trauma management in postgraduate surgical education

The activities of a trauma service in a university hospital were analyzed to test the hypothesis that operative caseload alone does not adequately measure the trauma experience of a surgical resident. Over a 2-year period, 378 victims of major trauma (blunt in 79%) were admitted to the service. Only 41% of them required a major operation by the Trauma Service. The patients spent an average of 2.8 days in the intensive care unit and often presented complex challenges in surgical critical care, including ventilator support and hemodynamic monitoring. A trauma service in a university center manages significant numbers of patients with multisystem injuries who never undergo a general surgical procedure. This experience constitutes such an important component of surgical education in trauma that it should be recognized by agencies accrediting residents and training programs. Completion of surgical residency should also imply competence in critical care of surgical patients.

Blunt liver trauma in children: nonoperative management

Since 1978, we have treated 19 of 23 (83%) children with blunt liver trauma nonoperatively. Management consisted of observation in an intensive care unit, repeated physical examination, frequent reevaluation of laboratory values, special investigations, and bed rest. The 19 patients all remained stable, required no surgical intervention, and showed resolution of the hepatic injuries with no early or delayed complications. Ultrasonography, although not as reliable a method as computed tomography or liver isotope scans for identification of hepatic trauma at first presentation, provided a very useful method for documenting subsequent progress and eventual healing of the lesions. The presence of an isolated hepatic injury is insufficient indication for surgery. If there is significant extrahepatic injury requiring surgery, or if the patient with hepatic trauma is deteriorating, operative intervention is mandatory.     

Selective nonoperative management of blunt splenic trauma in adults

The use of selective nonoperative management of blunt splenic trauma in adults is based on the undeniable benefits of this approach in children. Proper patient selection requires hemodynamic stability, lack of generalized peritoneal irritation, and minimal blood transfusion needs. Computed tomography is now used to make the diagnosis, but the decision for laparotomy is based on clinical grounds. Forty-one (87%) of 47 patients selected for nonoperative management were treated successfully without laparotomy, while the remaining 6 patients underwent delayed operations for persistent splenic bleeding. Blood transfusion requirements were significantly less in the observed group than in the operative group for patients with isolated trauma and for patients with polytrauma. There were no known missed intra-abdominal injuries and no deaths with the nonoperative approach. Analysis of our results has confirmed that nonoperative management is a safe and effective alternative to immediate laparotomy in properly selected patients and it can result in splenic salvage without the need for an operation.     

Operative vs nonoperative management of blunt pancreatic trauma in children

Purpose

The aim of this study was to evaluate the outcome of nonoperative vs operative management of blunt pancreatic trauma in children.

Methods

Retrospective review of pancreatic injuries from 1995 to 2006 at an urban level I regional pediatric trauma center.

Results

Forty-three children with pancreatic injury were included in the analysis. Injuries included grade I (n = 18), grade II (n = 6), grade III (n = 17), and grade IV (n = 2). For grade II to IV injuries, patients managed operatively (n = 14) and nonoperatively (n = 11) had similar lengths of stay and rates of readmission, despite increased pancreatic complications (PCs) in the nonoperative cohort (21% vs 73%; P = .02). There was a trend toward increased non-PCs in patients managed with resection (P = .07). Twelve patients underwent successful diagnostic endoscopic retrograde cholangiopancreatography in which duct injury was identified. In this group, nonoperative management was pursued in 6 patients but was associated with increased rates of PC (86% nonoperative vs 29% operative; P = .02).

Conclusions

Operative management of children with grades II to IV pancreatic injury results in significantly decreased rates of PCs but fails to decrease length of stay in the hospital, possibly as a result of non-PCs. Endoscopic retrograde cholangiopancreatography may serve as a useful diagnostic modality for guiding operative vs nonoperative management decisions.     

The significance of pseudoaneurysms in the nonoperative management of pediatric blunt splenic trauma

Purpose

Nonoperative management is the standard of care for hemodynamically stable pediatric and adult blunt splenic injuries. In adults, most centers follow a well-defined protocol involving repeated imaging at 24 to 48 hours, with embolization of splenic pseudoaneurysms (SAPs). In children, the significance of radiologically detected SAP has yet to be clarified.

Methods

A systematic review of the medical literature was conducted to analyze the outcomes of documented posttraumatic SAP in the pediatric population.

Results

Sixteen articles, including 1 prospective study, 4 retrospective reviews, and 11 case reports were reviewed. Forty-five SAPs were reported. Ninety-six percent of children were reported as stable. Yet, 82% underwent splenectomy, splenorrhaphy, or embolization. The fear of delayed complications owing to SAP was often cited as the reason for intervention in otherwise stable children. Only one child with a documented pseudoaneurysm experienced a delayed splenic rupture while under observation. No deaths were reported.

Conclusions

There is no evidence to support or dispute the routine use of follow-up imaging and embolization of posttraumatic SAP in the pediatric population. At present, the decision to treat SAP in stable children is at the discretion of the treating physician. A prospective study is needed to clarify this issue.     

A nonoperative approach to the adult ruptured spleen sustained from blunt trauma

From 1978 to 1983, 53 consecutive adult patients with ruptured spleens documented by radionuclide studies, computerized axial tomography, or surgery, were evaluated at William Beaumont Hospital. Thirty-four patients (64%) underwent an exploratory laparotomy; 33 resulted in a splenectomy and one patient had an attempted splenorraphy which failed. Nineteen patients (36%) were hemodynamically stable on admission, or had transient episodes of hypotension readily reversed by intravenous fluids. They were placed at strict bedrest under intensive monitoring. Two patients deteriorated clinically and were taken to surgery, resulting in a splenectomy on the fourth and sixth hospital day, respectively. Seventeen patients (32%) were successfully treated nonoperatively, representing an 89 per cent success rate. The average admitting hemoglobin in the nonoperative group was 13.2 gm/dl, with an average drop of 1.6 gm/dl, and an average total blood transfusion of 1.2 units. These patients were followed for an average of 19.2 months, with no sequelae from their splenic injury. In a hemodynamically stable adult patient with a splenic injury sustained from blunt trauma, a nonoperative approach is a viable alternative when close intensive monitoring is available.

Ultrasonography for interval assessment in the nonoperative management of hepatic trauma

Abdominal ultrasonography (US) is gaining widespread acceptance as a valuable diagnostic tool in the initial evaluation of trauma victims. We investigated the utility of US as a follow-up radiologic study in nonoperative hepatic trauma. Patients with liver injury designated for nonoperative management were prospectively studied over a 2-year period at our primary adult resource center for trauma. Computed tomography (CT) and radiologist-performed US were obtained at admission and at 1 week. The ability of US to detect lesions, fluid, and complications was evaluated by comparing with the corresponding CT. Twenty-five hepatic trauma patients in the study were successfully managed nonoperatively and had both initial and follow-up US and CT scans: 1 (4%) grade I, 5 (20%) grade II, 7 (28%) grade III, 7 (28%) grade IV, and 5 (20%) grade V. Four complications developed [biloma (3) and biliary fistula (1)] in 3 patients with grade IV injury and 1 with a grade II injury. Interval US appropriately detected a complication or confirmed the absence of complication in all (13/13, 100%) patients with low-grade (I-III) injury and only missed a small biloma in one patient with a grade IV injury. Interval US and CT agreement was 92 per cent for change in hemoperitoneum or parenchymal lesion. Ultrasonography is a convenient imaging modality in the evaluation of hepatic trauma. US is sufficient to detect or exclude complications in low-grade injuries. In high-grade injuries, US may be an adjunct to CT for definitive interval assessment.     

Role of repeat computerized tomography in nonoperative management of solid organ trauma

Nonoperative management (NOM) of blunt spleen and liver trauma is currently well accepted. CT imaging is helpful in selecting treatment options and to evaluate resolution of solid organ trauma. This 8-year study was undertaken to assess the role of repeat CT scans in NOM by analyzing indications of surgery in NOM failures. NOM was undertaken in 221 patients with spleen/liver trauma. After initial CT scans, 82 (37%) scans were repeated in 65 patients. There was failure of NOM (NOMF) in 11 patients. Follow-up imaging was done prior to delayed surgery in 4 (36%) patients, 4.9 per cent of repeat scans. Two of these patients had hemodynamic instability and, in the other two, there were clinical signs of peritonitis. The remaining seven patients had delayed surgery due to hemodynamic instability. There is a limited role of repeat CT scans in NOM of spleen and liver trauma. Repeat CT should be done more liberally in patients with suspected intestinal and mesenteric trauma, unexplained blood loss, complex hepato-biliary trauma, and in patients with neurological or pharmacological paralysis.     

The nonoperative management of fistula-in-ano

BACKGROUND/PURPOSE: Fistulotomy is the accepted treatment for infants with perianal fistula. Although recurrence rates range from 0% to 68%. Based on the experience of a senior colleague who noted that babies suffering from perianal fistula follow a self-limited course the authors decided to determine if this observation was accurate. METHODS: A conservative approach to perianal abscess and fistula was used prospectively in 18 male infants. Abscesses were to be drained only if the baby was very uncomfortable or febrile. Once a fistula developed the authors continued observation until the fistula healed. Data are expressed as mean +/- SD. Mean follow-up period was 37 months. RESULTS: Mean age at onset of symptoms was 4 +/- 3 months. Fistulas developed in 14 patients (77%). All fistulas healed without operation. Four patients had abscesses drained for discomfort (n = 3) or fever (n = 1). No patient required antibiotics. Mean duration of symptoms was 6 +/- 4 months. Four patients in whom fistulas did not form healed after incision (n = 3) or spontaneous drainage (n = 1). All patients currently are asymptomatic. CONCLUSIONS: In healthy neonates, perianal abscess and fistula are self-limited conditions rarely requiring surgical drainage and not requiring antibiotics. The conservative management of perianal abscess and fistula in healthy infants appears to be safe and effective.     

Predictive factors of operative or nonoperative management of blunt hepatic trauma

AIM: Nonoperative management (NOM) has revolutionized the care of blunt hepatic trauma patients. The aim of the present study was to identify and evaluate the predictors of NOM of these patients. METHODS: The Trauma Registry data of 55 consecutive adult patients admitted with blunt hepatic trauma over a 4-year period was reviewed. Patients were divided into immediately operated (OP-group) and selected for NOM (NOM-group). Factors analyzed were: demographics, injury mechanism, initial vital signs, liver injury grade, concomitant injuries, and total injury severity scoring systems. RESULTS: Concomitant abdominal trauma, high Injury Severity Score (ISS), low International Classification of Diseases 9(th) revision Injury Severity Score (ICISS), and low probability of survival (Ps) were predictors for operative management. Compared to NOM-patients (66%, N=36), OP-patients (34%, N=19) suffered more frequently concomitant abdominal injuries (84.2% vs 47.2%, P=0.004) and were more severely totally injured as expressed by higher ISS (25 vs 20, P=0.01), lower ICISS (0.51 vs 0.74, P=0.003), and lower Ps (0.81 vs 0.98, P=0.005). NOM resulted in lower intensive care unit admission and mortality rates (47.2% vs 78.9%, P=0.002 and 2.7% vs 15.8%, P=0.03, respectively). NOM-success rate was 92%. CONCLUSION: NOM of blunt hepatic trauma is safe and efficient. Concomitant abdominal trauma, ISS, ICISS, and Ps are predictors for operative or nonoperative management.     

Changing patterns in the management of splenic trauma: the impact of nonoperative management.

OBJECTIVE: The recognition that splenectomy renders patients susceptible to lifelong risks of septic complications has led to routine attempts at splenic conservation after trauma. In 1990, the authors reported that over an 11-year study period involving 193 patients, splenorrhaphy was the most common splenic salvage method (66% overall) noted, with nonoperative management employed in only 13% of blunt splenic injuries. This report describes changing patterns of therapy in 190 consecutive patients with splenic injuries seen during a subsequent 6-year period (1990 to 1996). An algorithmic approach for patient management and pitfalls to be avoided to ensure safe nonoperative management are detailed. METHODS: Nonoperative management criteria included hemodynamic stability and computed tomographic examination without shattered spleen or other injuries requiring celiotomy. RESULTS: Of 190 consecutive patients, 102 (54%) were managed nonoperatively: 96 (65%) of 147 patients with blunt splenic injuries, which included 15 patients with intrinsic splenic pathology, and 6 hemodynamically stable patients with isolated stab wounds (24% of all splenic stab wounds). Fifty-six patients underwent splenectomy (29%) and 32 splenorrhaphy (17%). The mean transfusion requirement was 6 units for splenectomy survivors and 0.8 units for nonoperative therapy (85% received no transfusions). Fifteen of the 16 major infectious complications that occurred followed splenectomy. Two patients failed nonoperative therapy (2%) and underwent splenectomy, and one patient required splenectomy after partial splenic resection. There no missed enteric injuries in patients managed nonoperatively. The overall mortality rate was 5.2%, with no deaths following nonoperative management. CONCLUSIONS: Nonoperative management of blunt splenic injuries has replaced splenorrhaphy as the most common method of splenic conservation. The criteria have been extended to include patients previously excluded from this form of therapy. As a result, 65% of all blunt splenic injuries and select stab wounds can be managed with minimal transfusions, morbidity, or mortality, with a success rate of 98%. Splenectomy, when necessary, continues to be associated with excessive transfusion and an inordinately high postoperative sepsis rate.     

Blunt hepatic trauma in children: experience with operative and nonoperative management

Between 1974 and 1982, 32 children were treated for blunt hepatic trauma. Twenty-three injuries were secondary to motor vehicle accidents. Twenty-three patients had associated injuries. The hepatic injury was treated surgically in 18 patients. Urgent surgery for massive bleeding was required in 7 patients; 8 underwent laparotomy for continued bleeding after initial stabilization; 2 underwent laparotomy for marked abdominal tenderness, and 1 for an expanding hepatic hematoma. Various excisional, debridement, suture, and drainage procedures were employed. Seven patients died, 5 from uncontrollable bleeding and 2 from associated severe head injury. The eleven survivors did well. The only postoperative complications were two wound infections. Fourteen patients were managed nonoperatively. Liver scan provided the diagnosis in all. Five of these patients required blood transfusion, and the mean volume of transfusion was 33cc/kg. The hospital courses in all cases were uneventful, and there were no late complications. A follow-up liver scan was obtained in 11 patients, showing resolution of the injury in all. We conclude that laparotomy is necessary for hepatic injury when it is associated with continuous massive bleeding. Hemodynamically stable patients can be managed nonoperatively, even when the blood-transfusion requirements are significant.     

Aortic intimal injuries from blunt trauma: resolution profile in nonoperative management

OBJECTIVE: To provide preliminary data on the resolution profile of aortic intimal injuries treated nonoperatively and on the safety of nonoperative management of these injuries. METHODS: Five blunt trauma patients diagnosed by transesophageal echocardiography (TEE) with traumatic intimal injury of the aorta were assigned to nonoperative management. This included beta-blockade to maintain systolic blood pressure between 80 and 90 mm Hg and heart rate between 60 and 80 beats/min, serial TEE studies, and invasive monitoring in the intensive care unit. The evolution of injury, the effectiveness of nonoperative treatment, and the potential need for an operative intervention were monitored. RESULTS: The patients had a mean Injury Severity Score of 32 and sustained multiple associated thoracic and extrathoracic injuries. Aortic injuries were located at the level of the ligamentum arteriosum and in the descending aorta adjacent to the diaphragm in three and two patients, respectively. The mean size of injury was 12.5 mm (range, 5-20 mm) and a thrombus attached to the endothelium was present in three of the five patients. Complete resolution of injury occurred within 9.4 +/- 6.6 days (range, 3-19 days). All patients remained hemodynamically stable and adequately perfused. All demonstrated progressive resolution of their aortic intimal injuries. No complications related to the aortic injuries were identified during a mean follow-up of 16.8 months. CONCLUSION: This small series suggests that aortic intimal injuries smaller than 20 mm in hemodynamically stable patients treated with beta-blockade resolve within several days. This approach appears safe when monitored by serial TEE studies performed by experienced experts, and continuous invasive hemodynamic monitoring.     

Laparoscopic treatment of biliary peritonitis following nonoperative management of blunt liver trauma

Introduction  

Nonoperative management (NOM) of hemodynamically stable patients with blunt hepatic injuries is considered the current standard of care. However, it is associated with several in-hospital complications. In selected cases laparoscopy could be proposed as diagnostic and therapeutic means.
