The impact of operative bleeding on outcome in transplantation of the liver.
Excessive operative blood transfusion has been correlated with an increased rate of infectious complications and lower survival rate after transplantation of the liver. Two hundred and five consecutive transplants of the liver, performed between January 1988 and December 1989, were studied retrospectively to determine preoperative risk factors associated with an increased operative blood loss and to evaluate the impact of operative transfusion on the outcome of transplantation. Preoperative clinical and laboratory parameters in patients who required 10 units or more of banked erythrocytes were compared with those in patients who received less than ten units of erythrocytes. ⋯ Patients who required more blood also had significantly prolonged stays in the intensive care units postoperatively (18.3 versus 6.3 days, p < 0.002) and lower graft and patient survival rates (p < 0.001 and p < 0.05, respectively). We conclude that intraoperative bleeding has remained a significant problem affecting the immediate outcome after transplantation of the liver. Preoperative parameters cannot predict operative bleeding accurately and the mainstay to prevent bleeding is a meticulous surgical technique during the hepatectomy and correction of coagulation abnormalities throughout the procedure.

In the present study, generally accepted risk factors for developing a primary incisional hernia are reviewed for their influence on the development of recurrent incisional hernia. The records of 417 patients undergoing an incisional hernia repair between 1980 and 1989 at the University Hospital Rotterdam were reviewed retrospectively, and in the event no hernia recurrence was documented, patients were asked to visit the outpatient department for physical examination. Patients having a primary incisional hernia (n = 302) were selected and patient related factors of gender, age, obesity, chronic cough, prostatism, constipation, diabetes mellitus and the use of corticosteroids were analyzed. ⋯ Considering these facts, a better technique is badly needed. In large defects, the use of inlay of prosthetic material consistently has the lowest recurrence rates. The question remains whether or not prosthetic material is also needed for repair of smaller hernias.
