Abstract:
Unique case of retained needle in the AirSeal trocar during robot-assisted laparoscopic radical prostatectomy. A 68-year-old male with prostate cancer underwent robot-assisted laparoscopic radical prostatectomy. Upon laparoscopic removal of final intra-abdominal suture by bedside assistant, needle became dislodged from suture and was unable to be located after a standard systematic search. Ultimately, needle was found caught in the assistant's AirSeal trocar device. Intraoperative loss of a foreign body should include inspection, and possible radiographic evaluation, of the trocar mechanism as part of a complete systematic approach.

Avoidance Learning and Learned Helplessness
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
