Duodenopancreatectomia no trauma: relato de caso / Duodenopancreatectomy in trauma: case report

A duodenopancreatectomia é rara no trauma, entretanto, em algumas situações é necessária, como ocorre nas lesões complexas da confluência biliopancreática. O grau da lesão, tipo do trauma, estabilidade hemodinâmica e a condição homeostática do paciente no momento da cirurgia são fatores que determinam a técnica cirúrgica a ser utilizada no trauma. Este relato objetiva demonstrar tipo de lesão grave e rara no trauma com seu resultado, além da opção de reconstrução do trânsito biliar e anastomose pancreato-duodenal.

The duodenopancreatectomy is rare in trauma, however, in some situations it is necessary, eg in complex lesions of the Duodeno-pancreatic confluence. The degree of injury, type of trauma, hemodynamic stability and homeostatic condition of the patient at the time of surgery are the factors that determine the surgical technique to be used in trauma. This case report aims to demonstrate a type of rare and severe injury in trauma with the result, plus the option of biliary transit reconstruction and pancreato-duodenal anastomosis.

Trauma do pâncreas: fatores preditivos de morbidade e mortalidade relacionados a índices de trauma / Trauma of pancreas: predictor's factors of morbidity and mortality related to trauma index

Contexto: Embora incomuns, lesões traumáticas do pâncreas estão associadas a significativos níveis de complicações e mortalidade. OBJETIVO: Definir os fatores preditivos de morbidade e mortalidade em pacientes vítimas de trauma pancreático. MÉTODO: Foram estudados 131 pacientes atendidos pela Disciplina de Cirurgia do Trauma no Hospital de Clínicas da Universidade Estadual de Campinas, SP, no período entre janeiro de 1994 a dezembro de 2007, com seus parâmetros epidemiológicos, fisiológicos e anatômicos, sendo comparados e analisados aos fatores preditivos de evolução, com estudo estatístico. Resultados: Trauma penetrante, com predomínio de ferimentos por projétil de arma de fogo ocorreu em 64 por cento dos casos. A maioria, 91,6 por cento, era do sexo masculino e a idade média de 29,8anos. A morbidade global foi de 64,9 por cento, com 29 por cento de complicações diretamente relacionadas ao pâncreas, como fístulas e sangramento. A mortalidade foi de 27,5 por cento, principalmente em decorrência de choque hipovolêmico e falência de múltiplos órgãos e sistemas. Houve maior morbidade e mortalidade em pacientes com lesões complexas (graus IV e V) do pâncreas quando comparadas com lesões menos graves (graus I e II), porém a morbidade e mortalidade neste grupo não foram desprezíveis, devido a valores alterados de escore de trauma revisado ("revised trauma score"), valores elevados de índice de gravidade da lesão ("injury severity score") e "abdominal trauma index". Conclusões: Valores alterados de "revised trauma score", pressão arterial sistólica menor que 90 mm Hg, valor de "injury severity score" menor ou igual a 15 e valor de "abdominal trauma index" maior ou igual a 25 são fatores relacionados a aumento da morbidade. Valores anormais de "revised trauma score", valores de "injury severity score" e "abdominal trauma index" superiores a 25, pressão arterial sistólica inferior a 90 mm Hg são fatores preditivos de aumento de mortalidade...

Context: Although relatively uncommon, traumatic pancreatic injury is associated with significant morbidity and mortality. OBJECTIVE: To define the predictors' factors of increase in the morbidity and mortality in patients with pancreatic trauma. METHOD: In this casuistic 131 patients were studied, since January 1994 through December 2007, with theirs epidemiological, physiological and anatomic parameters compared and the analysis of the predictive values for the occurrence of bad evolution, with an appropriate statistical study. Results: Penetrating trauma occurred in 64 percent and blunt trauma in 36 percent, and 91.6 percent was male. The mean age was 29,8 years. The global morbidity in this series was 64.9 percent with 29 percent prevalence of pancreas related complications, such as pancreatic fistula and bleeding occurrence. The overall mortality was 27.5 percent and occurred by hemorrhagic shock and multiple organs and system failed. CONCLUSIONS: Higher morbidity and mortality was related with complex injuries of the pancreas (grade IV and V), but morbidity and mortality in the group of injuries grade I and II are not minimal in patients with changed values of revised trauma score and high values of injury severity score and abdominal trauma index. Systolic blood pressure lower 90 mm Hg, changed values of revised trauma score index, values of injury severity score higher 15 and values of abdominal trauma index higher 25 are predictive factors of morbidity. Changed values of revised trauma score, values of injury severity score or abdominal trauma index higher 25, systolic blood pressure are predictive factors of mortality in patients with pancreatic trauma. Low values of TRISS are predictive of higher morbidity and mortality, but high values of TRISS are not predictives of satisfactory evolution.

Usefulness of CT and ERCP in Traumatic Pancreatic Injury

PURPOSE: To evaluate the usefulness of CT and ERCP in the diagnosis of traumatic pancreatic injury, and the degree of such injury. MATERIALS AND METHODS: Using CT (n=30) and ERCP (n=8), we retrospectively analyzed 30 cases of surgically proven traumatic pancreatic injury. Both CT and surgical findings were evaluated according to intra-and extra- pancreatic change and assigned to one of five grades, according to their pattern. ERCP findings were categorized as normal mass effect, parenchymal staining, or extravasation of contrast material. In all 30 cases CT and ERCP findings were compared with surgical findings. RESULTS: Pancreatic enlargement was the most common finding of intrapancreatic change in 21(67%) cases (67%). In 20 of 30 cases, there was good correlation between the CT grade and surgical grading. Of the remaining ten cases, seven cases (23%) were underestimated and three(10%) were overestimated. CT grade III or IV suggest pancreatic duct injury ; in two of 13 cases with this grade, such injury was not seen on surgery, however. Of the eight cases in which ERCP was performed, two were normal, one showed mass effect, one showed parenchymal staining, and four, all of which showed pancreatic duct injury on surgery, showed extravasation of contrast material. Two of these four cases were CT grade II, but on surgery, proven duct injury was seen. CONCLUSION: In cases of pancreatic duct injury, ERCP is superior to CT; where such injury is suspected, it should therefore be used to determine whether or not the injury is in fact present.
