Comparative StudyLong-term outcome of laparoscopic surgery for pancreatic neuroendocrine tumors.
As most pancreatic neuroendocrine tumors (PNET) are relatively small and solitary, they may be considered well suited for removal by a minimally invasive approach. There are few large series that describe laparoscopic surgery for PNET. The primary aim of this study was to describe the feasibility, outcome, and histopathology associated with laparoscopic pancreatic surgery (LS) of PNET in a large series. ⋯ LS of PNET is feasible with acceptable morbidity and a good overall disease-specific long-term prognosis.

Comparative StudyLaparoscopic versus open surgery for stage I rectal cancer: long-term oncologic outcomes.
Laparoscopic resection is increasingly being performed for rectal cancer. However, few data are available to compare long-term outcomes after open versus laparoscopic surgery for early-stage rectal cancer. ⋯ Long-term outcomes of laparoscopic surgery for stage I rectal cancer were comparable to those of open surgery. Laparoscopic surgery, however, produced more favourable short-term outcomes than open surgery.

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.
