Injury to the diaphragm from penetrating or blunt thoracoabdominal trauma is notoriously difficult to diagnose. Chest radiography, computed tomography scan, contrast studies, diagnostic peritoneal lavage, and laparoscopy are inadequate; thus, celiotomy is commonly performed in patients with suspected diaphragmatic injury. We compared the diagnostic accuracy of video-assisted thoracoscopic surgery (VATS) with that of exploratory celiotomy in the evaluation of diaphragmatic and thoracoabdominal injury. ⋯ Video-assisted thoracoscopy is a safe, expeditious, and accurate method of evaluating the diaphragm in injured patients, and is comparable in diagnostic accuracy to exploratory celiotomy.

The orthopedic surgeon has several options available for blood conservation. Preoperative autologous donation (PAD) of blood is a cost-effective measure when the cost of managing transfusion-transmitted infectious disease is considered; overuse and underuse are expensive problems, however. Hemodilution, while used successfully in prostate surgery, is logistically impractical in joint replacement centers. ⋯ Studies are under way to determine whether this method of blood conservation alters transfusion requirements. Recombinant human erythropoietin (Epoetin alfa) has a role in elective procedures with significant blood loss, including complex revision joint replacement, bilateral joint arthroplasty, and spinal fusion. Preoperative Epoetin alfa administration enhances preoperative autologous blood collection and increases perioperative red blood cell mass.

Conservative use of allogeneic red blood cell (RBC) transfusion is a growing trend in cardiovascular surgery. Recent advances in blood conservation measures have reduced, and in some cases eliminated, the need for allogeneic RBC transfusions in some of these patients. ⋯ Meticulous surgical technique, moderate hemodilution, aprotinin, hemostatic techniques, blood salvage, and autotransfusion are intraoperative measures that can reduce blood loss. Postoperatively, even severe blood deficits can often be restored with adequate diet and rest and the use of actinics.

The technique of lymphoscintigraphy may allow a more selective approach to the management of clinically negative neck nodes among patients with cutaneous head and neck melanoma. ⋯ Lymphoscintigraphy and sentinel node biopsy are more difficult to perform in the head and neck than in other parts of the body. The reliability of sentinel node biopsy based on lymphoscintigraphy may be improved by identifying and marking all nodes that are considered to receive direct lymphatic drainage from the primary melanoma, and by use of a gamma probe intraoperatively.
