Case ReportsPreoperative diagnosis of isolated penetrating gallbladder injury in an asymptomatic patient: the role of hepato-iminodiacetic acid scan as the definitive diagnostic test.
The decision for nonoperative treatment of abdominal stab wounds is usually based on clinical examination findings. It is important, however, to identify patients who may suffer occult injuries and, therefore, be benefited from further diagnostic evaluation. ⋯ A high index of suspicion and appropriate selection of imaging studies may lead to early identification. Hepato-iminodiacetic acid scan can be used as the definitive diagnostic imaging test in such occasions.

Computed tomographic grading is useful in the selection of patients for nonoperative management of blunt injury to the spleen.
Although nonoperative management of blunt splenic injury (NMBSI) has an established role in the overall management of adult patients with blunt splenic injury, the criteria by which patients are selected continue to be debated. The purpose of this study is to establish the effectiveness of a defined set of criteria that includes CT grading for the selection of patients for NMBSI by examining the outcomes of patients managed in this manner 1 year before with those 1 year after the implementation of this specific set of selection criteria. All patients hospitalized at St. ⋯ In Group II, after the implementation of selection criteria that included CT grade, no patient required delayed operation. Eleven underwent immediate operation, whereas 18 were successfully managed nonoperatively. We conclude that, in the hemodynamically stable patient without clinical indication for laparotomy, CT grading of the splenic injury is a reliable criterion by which patients may be selected for nonoperative management.

Randomized Controlled Trial Clinical TrialRole of prophylactic antibiotics for tube thoracostomy in chest trauma.
The objective of this study was to evaluate the efficacy of antibiotic prophylaxis in association with tube thoracostomy for chest trauma patients with Injury Severity Scores of 9 or 10. A double-blind randomized clinical trial of patients requiring tube thoracostomy was performed at an urban Level 1 trauma center. All patients included in this series were patients with Injury Severity Scores of 9 or 10 (hemothorax/pneumothorax) who suffered isolated chest trauma secondary to blunt or penetrating trauma. ⋯ In the 71 patients receiving antibiotic, 7 complications (1 pleural effusion, 2 chest tube reinsertions, 4 additional chest tubes) occurred, none of which were infectious. In the 68 patients receiving placebo, 7 complications (2 empyemas, 2 pneumonias with effusions, 1 pleural effusion, 2 chest tube reinsertions) occurred, 4 of which were infectious and required antibiotic intervention (P = 0.05, Fisher's exact test). This study showed that patients receiving antibiotics have a significantly reduced incidence of infectious complications and suggests that patients who undergo tube thoracostomy for chest trauma would benefit from administration of prophylactic antibiotics.

Comparative Study Clinical TrialPreoperative versus postoperative chemoradiation for patients with resected pancreatic adenocarcinoma.
Two groups of patients with adenocarcinoma of the pancreas treated with either preoperative chemoradiation (preop CTRT) or postoperative chemoradiation (postop CTRT) were retrospectively analyzed for various treatment-related parameters. Between November 1986 and October 1996, a total of 70 patients with pancreatic adenocarcinoma were enrolled into preop CTRT protocols at our institution. Twenty-five patients with adenocarcinoma of the head of the pancreas underwent pancreaticoduodenectomy with curative intent. ⋯ Local failure either alone or as a component of distant failure occurred in 16 per cent (4 of 25 patients) with preop CTRT and 16.6 per cent (3 of 18) with postop CTRT. Analysis of differences between those treated with preoperative and postoperative CTRT demonstrates similarity in toxicity and effects. However, 22 per cent of patients intended for postoperative therapy did not receive treatment.

Gamma-probe-guided resection of the sentinel lymph node in breast cancer.
Regional lymph node metastases in patients with breast cancer have fundamental staging, prognostic, and treatment implications. Classically, axillary lymph node sampling requires a dissection under general anesthesia. The concept that a primary, or sentinel, lymph node is the first node to receive drainage from a tumor has been established in patients with malignant melanomas using radiolabeled tracers and vital dyes. ⋯ Sentinel lymph node scintigraphy and biopsy accurately predicted the axillary lymph node status in 41 of 42 patients (98%). Scintigraphy can identify sentinel lymph nodes in a large majority of patients. Sentinel lymph node biopsy is an accurate predictor of axillary lymphatic metastases.
