Experiência do Hospital João XXIII no tratamento não-operatório de vísceras abdominais Maciças / Hospital John XXIII's experience in non-surgical treatment of solid abdminal visceras

O tratamento não-operatório (TNO) de pacientes traumatológicos hemodinamicamente estáveis passou a ser a conduta terapêutica mais adequada nos centros de trauma, com altos índices de sucesso e baixas taxas de complicações. Os fatores determinantes para essa conduta foram o uso de tomografia computadorizada e a organização de centros com infraestrutura adequada para o monitoramento desses pacientes. As falhas do TNO são poucas e o seu sucesso é a regra em mais de 90% das vezes. Outro fator responsável pelo sucesso do TNO é a adoção de medidas minimamente invasivas, como a angiografia e a colangiopancreatografia retrógrada endoscópica. Este artigo relata experiência do Hospital João XXIII, em Belo Horizonte, com o TNO entre novembro de 2004 e dezembro 2008.

The Non-surgical treatment (NST) of hemodynamically stable trauma patients has become the most appropriate therapeutic approach in trauma centers with high success rates and low complication rates. The determining factors for this behavior were the use of computed tomography and the organization of centers with adequate infrastructure for monitoring these patients. The NTS(TNO)failures are few and success is the rule in more than 90% of the cases. Another factor responsible for the NST success is the adoption of minimally invasive measures, such as angiography and endoscopic retrograde cholangiopancreatography. This article reports the experience with TNO/NST in Hospital João XXIII, in Belo Horizonte, between November 2004 and December 2008.

The Efficacy and Benefits of Transcatheter Arterial Embolization (TAE) in Patients with Blunt Splenic Injury

PURPOSE: To evaluate the efficacy and benefits of transcatheter arterial embolization(TAE) in patients with blunt splenic injury after blunt abdominal trauma. MATERIALS AND METHODS: We retrospectively analyzed the results of transcatheter arterial embolization in 23 patients who suffered splenic injury after blunt abdominal trauma. Fourteen of the patients were male, and 9 were female; 13 were adults, and 10 were children. Transcatheter arterial embolization was performed in patients with hypotension, tachycardia, evidence of hemodynamic instability due, for example, to low levels of Hgb and Hct, or those who needed fluid therapy or blood transfusion. After embolization the patients 'progress was monitored by CT scanning, abdominal sonography, or 99mTc-sulfur colloid scintigraphy. RESULTS: The degree of splenic injury was classified according to the system devised by Mirvis et al.; nine cases were CT grade III, and 14 were grade IV. After demonstrating angiographically the site of contrast leakage, embolization was performed; for this, a coil only was used in 16 cases, gelfoam only in four, and both coil and gelfoam in three. There were three sites of vascular embolization: 16 procedures were performed in the proxi-mal part of the main trunk of the splenic artery, four in a superselected branch of this same artery, and three in both the splenic artery and one of its superselected branches. Of the 23 cases, 18 recovered without splenectomy after embolization, three adult patients died from coexisting conditions (spinal or cerebral injuries, liver cir-rhosis, or pelvic bone fracture) or complications(acute renal failure or disseminated intravascular coagulation). Due to co-existing pancreatic and mesenteric vessel injury, two of the adult patients who underwent TAE also underwent delayed surgery; intraoperatively, there was no evidence of splenic rebleeding. In all patients who did not undergo surgery, follow-up observation revealed a decreased volume of hemoperitoneum, increased uptake of radionuclide in the spleen, and no evidence of rebleeding. CONCLUSION: Transcatheter angiography and arterial embolization in patients with splenic injuries who showed hemodynamic instability and a high CT grade is a non-surgical approach that can achieve early hemostasis and hemodynamic stability. Another benefit of this procedure is the preservation of splenic function.

A Comparison of Operative with Nonoperative Management of Traumatic Injuries to the Liver and Spleen

BACKGROUND: We analyzed the clinical characteristics of trauma involving the liver and/or the spleen to evaluate the safety of nonoperative management. METHODS: A retrospective study was conducted on 78 cases who were treated with operative (37 cases) and nonoperative (41 cases) management at Wonkwang University Hospital from January 1995 to June 1998. Nonoperative management was done in hemodynamically stable patients. RESULTS: Three cases in the operative group (OG) and 5 cases in the nonoperative group (NOG) were children. Causes of injury were traffic accidents (66.6%), falls (15.4%), penetrating injuries (11.4%), and assaults (6.4%). Associated intraabdominal injuries were renal contusions (42%), pancreatic injuries (18%), mesenteric tearing (12%), diaphragm ruptures (9%). Associated extraabdominal injuries were chest injuries (56.5%), long bone fractures (15.2%), pelvic bone fractures (9.8%), and CNS injuries (8.7%). Mean total blood requirements were 7.0 units in the OG and 1.2 units in the NOG. Complications were 35 cases in the OG (pleural effusion, 6 cases; intraabdominal abscess, 4 cases; pneumonia, 4 cases; biloma, 3 cases) and 15 cases in the NOG (pleural effusion, 5 cases; pneumonia, 5 cases; intraabdominal abscess, 2 cases). Causes of 8 delayed operations were bowel perforations (small bowel 2 cases, and colon, 1 case), bile peritonitis (2 cases), and hemodynamically instability (3 cases). The hospitalization period was 16 days in the OG and 14 days in the NOG. Six patients in the OG died and the causes were multiple organ failures (4 cases), hypovolemic shock (1 case), and ARDS (1 case). No patient died in the delayed operation cases and the NOG, even in major injury cases aquired respiratory distress syndrom. CONCLUSIONS: Nonoperative management of traumatic liver and/or spleen injury is safe and can be tried initially under the conditions of stable hemodynamics, feasible abdominal CT, and feasible immediate operation.
