Comparative StudyContinuous noninvasive hemoglobin monitor from pulse ox: ready for prime time?
Advances in technology have allowed for continuous noninvasive hemoglobin monitoring (SpHb), which may enable earlier detection of hemorrhage and more efficient surgical and/or blood transfusion management. The use of SpHb has not been described in the trauma population. The purpose of the present study was to evaluate the accuracy of a SpHb measurement device in severely injured trauma patients. ⋯ The continuous noninvasive hemoglobin monitor does not appear to represent serum hemoglobin levels accurately in severely injured trauma patients. However, we were able to identify utility for this noninvasive tool when Hgb was dichotomized into normal or low levels.

Comparative StudyEndoscopic versus open radiofrequency ablation for treatment of small hepatocellular carcinoma.
Surgical radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) is associated with superior oncological outcome in comparison with percutaneous RFA. The present study aimed to retrospectively evaluate the relative perioperative safety and postoperative outcome of the laparoscopic or thoracoscopic approach versus the open approach to RFA for small HCC. ⋯ In consideration of operative invasiveness and postoperative recovery, LTS RFA is superior to the open approach in patients with small HCC. Moreover, the surgical outcome did not differ between the two approaches. Laparoscopic/thorascopic RFA can be considered to be a useful procedure for ablation therapy.

Comparative StudyPreoperative magnetic resonance angiography as a predictive test for cerebral ischemia during carotid endarterectomy.
To evaluate whether the preoperative magnetic resonance angiography (MRA) can predict the risk of cerebral ischemia associated with the carotid endarterectomy (CEA). ⋯ Preoperative MRA is valuable when predicting cerebral ischemia leading to an inevitable shunting during CEA. Therefore, if there are preoperative MRA findings such as multiple occlusive intracranial arteries in the contralateral hemisphere or the absence of patent communicating arteries, it is recommended that CEA be performed under general anesthesia with routine shunting to avoid a serious shunt-related complication.

Characterizing the global burden of surgical disease: a method to estimate inguinal hernia epidemiology in Ghana.
Surgical conditions represent an immense yet underrecognized source of disease burden globally. Characterizing the burden of surgical disease has been defined as a priority research agenda in global surgery. Little is known about the epidemiology of inguinal hernia, a common easily treatable surgical condition, in resource-poor settings. ⋯ Data generated by our method indicate the extent to which Ghana lacks the surgical capacity to address its significant inguinal hernia disease burden. This approach provides a simple framework for calculating inguinal hernia epidemiology in resource-poor settings that may be used for advocacy and program planning in multiple country contexts.
