Pancreatectomia distal no trauma: estudo multicêntrico

Fifty consecutive pancreatectomies without mortality

OBJECTIVE

to report the group's experience with a series of patients undergoing pancreatic resection presenting null mortality rates.

METHODS

we prospectively studied 50 consecutive patients undergoing pancreatic resections for peri-ampullary or pancreatic diseases. Main local complications were defined according to international criteria. In-hospital mortality was defined as death occurring in the first 90 postoperative days.

RESULTS

patients' age ranged between 16 and 90 years (average: 53.3). We found anemia (Hb < 12g/dl) and preoperative jaundice in 38% and 40% of cases, respectively. Most patients presented with peri-ampullary tumors (66%). The most common surgical procedure was the Kausch - Whipple operation (70%). Six patients (12%) needed to undergo resection of a segment of the mesenteric-portal axis. The mean operative time was 445.1 minutes. Twenty two patients (44%) showed no clinical complications and presented mean hospital stay of 10.3 days. The most frequent complications were pancreatic fistula (56%), delayed gastric emptying (17.1%) and bleeding (16%).

CONCLUSION

within the last three decades, pancreatic resection is still considered a challenge, especially outside large specialized centers. Nevertheless, even in our country (Brazil), teams seasoned in such procedure can reach low mortality rates.

Complications after pancreatectomies: prospective study after ISGFP and ISGPS new classifications

BACKGROUND

Scientific publications focusing on the results of pancreatic resections in Brazil are scarce.

AIM

To present the surgical results of pancreatic resections.

METHODS

Were analyzed prospectively 54 consecutive cases of patients undergoing consecutive pancreatectomy evaluating the occurrence of postoperative complications (pancreatic fistula, delayed gastric emptying and postoperative hemorrhage) based on the criteria of the International Study Group on Pancreatic Fistula Definition and International Study Group of Pancreatic Surgery.

RESULTS

Of the 54 pancreatectomy, 32 occurred in women (59,26%) and 22 in men (40,74%). The mean age of patients was 54,5 years. The most performed procedure was the Whipple operation, in 38 patients. In eight of those cases, mesenteric-portal confluence was ressected. The mean period of hospitalization was 20,7 days. The hospitalization in 51% of patients was up to 10 days. A pancreatic fistula was observed in 50% of the cases submitted to the Whipple surgery. The postoperative hemorrhage and delayed gastric emptying in patients undergoing the surgery occurred respectively in 13,15% and 18,41%. The overall morbidity and mortality was respectively 62.9% and 5.5%.

CONCLUSION

There is a need for the national publications to assimilate the concepts and criteria presented by the ISGFP(2) and ISGPS(23,25) to enable comparison of the results obtained with surgical treatment of pancreatic disorders, in the Brazilian context. Who knows, therefore, whether the great advanced seen in the last 40 years in terms of the reduction in mortality rates associated with pancreatic resections may also occur with the persistently high levels of postoperative complications.

[Trauma of pancreas: predictor's factors of morbidity and mortality related to trauma index]

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% and blunt trauma in 36%, and 91.6% was male. The mean age was 29,8 years. The global morbidity in this series was 64.9% with 29% prevalence of pancreas related complications, such as pancreatic fistula and bleeding occurrence. The overall mortality was 27.5% 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.

Preservação do baço na pancreatectomia distal por trauma

OBJETIVOS: A esplenectomia simplifica a pancreatectomia distal no trauma mas tem o inconveniente de aumentar a vulnerabilidade do paciente às infecções. O objetivo é avaliar se a preservação do baço na referida cirurgia é exeqüível e segura. MÉTODOS: A preservação do baço foi feita em 52 pacientes (48%) entre 108 submetidos à pancreatectomia distal. Quarenta e cinco (86,5%) do sexo masculino e sete (13,5%) do sexo feminino. Idade variou de seis a 42 anos com média de 22,1 anos. Trauma penetrante foi a causa da lesão em 35 (67%) com 27 (77%) por arma de fogo e oito (23%) por arma branca. Contusão foi responsável pela lesão em 17 (33%). RESULTADOS: Não houve óbito. Fístula pancreática ocorreu em seis (11,5%) pacientes; coleção subfrênica em seis (11,5%); pancreatite em dois (3,8%); abcesso de parede em quatro (8%); pneumonia em quatro (8%). Quarenta pacientes tiveram lesões associadas. O ISS médio foi de 19,3. O baço apresentava lesão em 13 pacientes. Sete foram submetidos à esplenorrafia e seis à ressecção parcial. Em 51 pacientes o baço foi conservado com os vasos esplênicos. Em um caso foi feita a ligadura proximal e distal dos vasos esplênicos (técnica Warschaw). Permanência hospitalar média de 12 dias. CONCLUSÃO: A pacreatectomia distal com preservação do baço mostrou ser segura nos pacientes estáveis, mesmo na presença de lesões associadas. A ausência de óbitos e a participação de cirurgiões em fase de treinamento confirmam sua segurança.
