Postoperative delirium is associated with decreased recovery of ambulation one-month after surgery.

Background: We hypothesized that postoperative delirium is associated with diminished recovery toward baseline preoperative ambulation levels one-month postoperatively.

Methods: Patients included were ≥60 years old undergoing inpatient operations. Ambulation was measured as steps/day using an accelerometer worn for ≥3-days preoperatively and ≥28-days postoperatively.

Single-incision laparoscopic surgery increases the risk of unintentional thermal injury from the monopolar "Bovie" instrument in comparison with traditional laparoscopy.

Background: Single-incision laparoscopic surgery (SILS) places multiple instruments in close, parallel proximity, an orientation that may have implications in the production of stray current from the monopolar "Bovie" instrument. The purpose of this study was to compare the energy transferred during SILS compared to traditional four-port laparoscopic surgery (TRD).

Method: In a laparoscopic simulator, instruments were inserted via SILS or TRD setup.
