Immunosuppression associated with homologous blood transfusion was first observed in renal allograft transplantation. Clinical effects of transfusion-induced immunosuppression in surgical patients have been debated in the literature for more than a decade with contradictory results. ⋯ Despite transfusion-induced immunomodulation, homologous blood transfusion should not be considered a risk factor for postoperative septic morbidity in patients undergoing elective major abdominal surgery. The timing-response relationship between transfusions and septic morbidity in multivariate analysis may be the effect of uncontrolled confounders such as variation of volemia induced by stress response in patients who were developing or had just developed infectious complications.

Comparative Study
Incidence of deep vein thrombosis after laparoscopic vs minilaparotomy cholecystectomy.
To determine the frequency of deep vein thrombosis (DVT) associated with minimally invasive cholecystectomy and to determine, using minilaparotomy cholecystectomy as a control operation, the influence of the laparoscopic pneumoperitoneum on DVT formation. ⋯ Despite the theoretical risk of thromboembolic disease due to use of the laparoscopic pneumoperitoneum, the frequency of DVT after either laparoscopic cholecystectomy or minilaparotomy cholecystectomy is low if adequate thromboprophylaxis is provided.

To characterize the current clinical presentation and management of neutropenic enterocolitis. ⋯ Neutropenic enterocolitis has evolved from a complication of patients with leukemia to a disease of patients receiving high-dose chemotherapy for many malignancies, solid as well as hematologic. Diagnosis of neutropenic enterocolitis continues to be a challenge, as patients typically present with nonspecific gastrointestinal tract symptoms. Neutropenia and computed tomographic scan findings are useful adjuncts in diagnosing neutropenic enterocolitis. Timely conservative treatment frequently allows resolution of neutropenic enterocolitis without operation.

Patients with hepatic metastases often develop obstruction of the intrahepatic inferior vena cava (IVC), known as IVC syndrome. This obstruction is debilitating due to the development of ascites and anasarca. ⋯ The debilitation of IVC syndrome due to ascites and anasarca can be considerably palliated by placement of transfemoral percutaneous stents.

To examine the hypothesis that the futility of short-term care for trauma patients requiring emergency operation can be determined based on the number of units of blood transfused and associated risk factors. ⋯ Although mortality among critically injured patients requiring operation and massive blood transfusion can be correlated with independent risk factors, discontinuation of short-term care cannot be justified based on the need for massive blood transfusion of up to 68 units.
