Comparative StudyLaparoscopic Liver Resection can be an Effective Way in Obese Patients: A Single Center of 2-Year Experience.
To evaluate the feasibility and safety of laparoscopic liver resection in obese patients, we compared the operative outcomes between obese and nonobese patients, also between laparoscopic liver resection and open liver resection of obese and nonobese patients. ⋯ Obesity should not be seen as a contraindication for laparoscopic liver resection, which is a safe and feasible procedure for obese patients.

Transanal Endoscopic Operation for Rectal Tumor: Short-term Outcomes and Learning Curve Analysis.
We aim to report outcomes and learning curve of transanal endoscopic operation (TEO) for rectal tumors, using standard laparoscopic instruments under a magnifying laparoscopic monitor view. ⋯ TEO is a feasible and safe treatment option for local excision of rectal tumors. TEO has the advantage of being a precise surgical procedure with a stable and magnifying endoscopic view. However, TEO requires a learning period and a careful selection of patients through proper indications and preoperative diagnostics.

Clinical TrialThe Effect of Equal Ratio Ventilation on Oxygenation, Respiratory Mechanics, and Cerebral Perfusion Pressure During Laparoscopy in the Trendelenburg Position.
The aim of this study was to investigate the effects of equal ratio ventilation (ERV) on oxygenation, respiratory mechanics, and the cerebral perfusion pressure during pneumoperitoneum in the Trendelenburg position. Thirty patients undergoing laparoscopic low anterior resection (25 to 65 y) were enrolled. Mechanical ventilator was set to volume-controlled mode at an inspiratory to expiratory (I:E) ratio of 1:2 with a tidal volume of 8 mL/kg of ideal body weight with a 5 cm H2O positive end-expiratory pressure. ⋯ No significant changes in arterial oxygen tension and respiratory compliance after adopting ERV. Mean arterial pressure and cerebral perfusion pressure decreased significantly over time after adopting the Trendelenburg position during pneumoperitoneum (P=0.014 and 0.005, respectively). In conclusion, there was no improvement in oxygenation or respiratory mechanics with ERV.
