Direct Cost Comparison of Open Carpal Tunnel Release in Different Venues.

Background: The increased efficiency and cost savings have led many surgeons to move their practice away from the traditional operating room (OR) or outpatient surgery center (OSC) and into the clinic setting. With the cost of health care continuing to rise, the venue with the lowest cost should be utilized. We performed a direct cost analysis of a single surgeon performing an open carpal tunnel release in the OR, OSC, and clinic. Methods: Four treatment groups were prospectively studied: the hospital OR with monitored anesthesia care (OR-MAC), OSC with MAC (OSC-MAC), OSC with local anesthesia (OSC-local), and clinic with local anesthesia (clinic). To determine direct costs, a detailed inventory was recorded including the weight and disposal of medical waste. Indirect costs were not included. Results: Five cases in each treatment group were prospectively recorded. Average direct costs were OR ($213.75), OSC-MAC ($102.79), OSC-local ($55.66), and clinic ($31.71). The average weight of surgical waste, in descending order, was the OR (4.78 kg), OSC-MAC (2.78 kg), OSC-local (2.6 kg), and the clinic (0.65 kg). Using analysis of variance, the clinic's direct costs and surgical waste were significantly less than any other setting (P < .005). Conclusions: The direct costs of an open carpal tunnel release were nearly 2 times more expensive in the OSC compared with the clinic and almost 7 times more expensive in the OR. Open carpal tunnel release is more cost-effective and generates less medical waste when performed in the clinic versus all other surgical venues.

Safety of preoperative erythropoietin in surgical calvarial remodeling: an 8-year retrospective review and analysis.

BACKGROUND: Calvarial remodeling is typically associated with significant blood loss. Although preoperative erythropoiesis-stimulating agents have proven to significantly decrease the need for blood transfusions, recent data in adults have raised concerns that elevating hemoglobin levels greater than 12.5 g/dl may increase the risk of thrombotic events. This study was designed to assess the risks of erythropoietin in the pediatric population. METHODS: Records were retrospectively reviewed from 2000 to 2008 at three major metropolitan children's hospitals of all children undergoing calvarial remodeling after receiving preoperative erythropoietin. Demographic and perioperative outcome data were reviewed, including transfusion reactions, pressure ulcer secondary to prolonged positioning, pneumonia, infection, deep vein thrombosis, cerebrovascular accident, pulmonary embolism, sagittal sinus thrombosis, pure red cell aplasia, and myocardial infarction. RESULTS: A total of 369 patients met the inclusion criteria (mean age, 0.86±1.1 years). On average, three preoperative doses of erythropoietin were administered (600 U/kg). Iron was also supplemented. No complications associated with dosing were noted, there were no thrombotic events identified, and no other major complications were seen (i.e., death or blindness). Thirty-one patients (8.40 percent) experienced one or more postoperative complications. There was no significant correlation between hemoglobin levels greater than 12.5 g/dl and the occurrence of any noted complication. CONCLUSIONS: With zero thrombotic postoperative complications, the authors estimate the risk of a thrombotic event in the pediatric population to be less than 0.81 percent (95 percent confidence). These data suggest that preoperative administration of erythropoietin in children undergoing calvarial remodeling does not appear to increase the incidence of thrombotic events or other significant complications. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Bladder diverticulum arising adjacent to an ectopic ureter presenting as a cystic mass.

Acquired bladder diverticula due to bladder outlet obstruction are not uncommon in the adult male population. Congenital diverticula originate adjacent to the trigone and are rarely diagnosed in adults. We report an unusual case of a diverticulum arising adjacent to an ectopic ureter located on the left lateral wall near the dome of the bladder. Although the diverticulum appeared to be congenital, its large size was likely a result of high pressure voiding. The patient underwent a transurethral resection of the prostate to reduce his bladder outlet obstruction, and subsequently underwent an open diverticulectomy.
