RESUMO
Objective To study the impact of blood transfusion on postoperative complications of pancreaticoduodenectomy.Methods The medical data of 356 patients who underwent pancreaticoduodenectomy from January 2005 to December 2011 were retrospectively analyzed.242 patients in the transfusion group received blood transfusion while the remaining patients in the non transfusion group received no blood transfusion.Results The rates of pancreatic fistula and pulmonary infection,mean operative time,intraoperative blood loss,and hospital stay were 17.8％,16.5％,6.4 h,920.0 ml and 29.1 d in the transfusion group compared with 8.8％,6.1％,5.4 h,150.0 ml and 25.9 d in the non-transfusion group,respectively (P＜0.05).However,there were no significant differences between the two groups in the rates of biliary fistula,gastrointestinal and intraabdominal bleeding,delayed gastric emptying and death.Conclusions Patients undergoing pancreaticoduodenectomy in the non-transfusion group had significantly lower rates of pancreatic fistula and pulmonary infection,shorter operative time and hospital stay,and less intraoperative blood loss.This study suggested that a reduction in intraoperative blood loss by advanced instruments and techniques,with operations carried out by experienced pancreatic surgeons in specialized pancreatic center,could result in a significantly lower postoperative complication rate.
RESUMO
Objective To analyse the CT findings of acute knee joint injury (AKJI) so as to evaluate the value and limitation of CT in the diagnosis of AKJI. Methods Sixty cases of AKJI were examined with X-ray plain film and thin-section of CT scanning, while three-dimensional reconstruction of CT was performed routinely as well. The results of X-ray films and CT scanning were analysed and compared with clinical data and operative findings retrospectively. Results In 60 cases of AKJI, 141 fractures were found on CT examination, however, only 104 fractures were found on X-ray films. The difference of the results between the two diagnostic imagings was statistically significant(?2=38.12, P
RESUMO
Objective To analyze the CT findings of acute cervical trauma (ACT) and evaluate the value and limitation of CT in the diagnosis of ACT. Methods 78 cases of cervical trauma were examined with X-ray film and thin slice CT. 3D reconstruction was performed routinely. Analysis and comparison of X-ray diagnosis with CT diagnosis were done. Results 60 cases of ACT were diagnosed by X-ray film while 59 cases were confirmed by CT simultaneously. 1 case was diagnosed by X-ray, while its CT findings were normal. Fracture detection rates of CT and X-ray film were 98.3% and 53.3%,respectively. The difference was statistically significant. Conclusion If the patient has the acute cervical trauma, CT can diagnose the fracture, luxation and spinal stenosis more safely and precisely. But CT scan has some limitations. Combining X-ray examination with CT scan is able to raise the diagnostic level.
