Randomized Controlled TrialIncidence of venous air embolism during myomectomy: the effect of patient position.
Venous air embolism (VAE) is characterized by the entrainment of air or exogenous gases from broken venous vasculature into the central venous system. No study exists regarding the effect of patient positioning on the incidence of VAE during abdominal myomectomy. The purpose of this study was to assess the incidence and grade of VAE during abdominal myomectomy in the supine position in comparison to those in the head-up tilt position using transesophageal echocardiography. ⋯ The incidence and grade of VAE in the head-up tilt group were significantly lower than those in the supine group during abdominal myomectomy.

Circumferential resection margin involvement in stage III rectal cancer patients treated with curative resection followed by chemoradiotherapy: a surrogate marker for local recurrence?
Circumferential resection margin (CRM) involvement is a well-known predictor for poor prognosis in rectal cancer. However, the significance is controversial in some studies. Accordingly, this study attempted to examine the prognostic impact of CRM involvement in stage III rectal cancer. ⋯ In this study, local recurrence rate did not differ according to CRM involvement status in stage III rectal cancer patients, although CRM involvement was shown to be an independent poor prognostic factor. Accordingly, validation of the results of this study by further large prospective randomized trials is warranted.

The change of prostate cancer treatment in Korea: 5 year analysis of a single institution.
We analyzed changes to the trends of prostate cancer management and patient characteristics at a single institute during 5 years due to the significant increase of the prostate cancer incidence and the robotic equipment in Korea. ⋯ As the prostate cancer incidence increased in Korea, the proportion of localized and locally advanced cancer also increased. In addition, the main treatment modality changed from non-surgical treatment to radical prostatectomy.

Cerebral oxygenation during laparoscopic surgery: jugular bulb versus regional cerebral oxygen saturation.
We hypothesized that regional cerebral oxygen saturation (rSO2) could replace jugular bulb oxygen saturation (SjvO2) in the steep Trendelenburg position under pneumoperitoneum. Therefore, we evaluated the relationship between SjvO2 and rSO2 during laparoscopic surgery. ⋯ There is little correlation between SjvO2 and rSO2 in the supine position and Trendelenburg-pneumoperitoneum condition during laparoscopic surgery.

The influence of the severity of chronic virus-related liver disease on propofol requirements during propofol-remifentanil anesthesia.
The purpose of this study was to investigate the influence of chronic virus- related liver disease severity on propofol requirements. ⋯ In this study, propofol requirements administered by target-controlled infusion to maintain similar depths of hypnosis were shown to depend on the severity of chronic virus-related liver dysfunction. In other words, patients with the most severe liver dysfunction required the least amount of propofol.
