Colonoscopic injection for murine solid cecal cancer model.

Background: The validity of current animal colon cancer models is questionable. This study was performed to evaluate whether colonoscopic injection of a murine colon cancer cell line into the cecal wall of immunocompetent rats leads to a solid tumor.

Methods: A bolus of bowel prep was given to BD-IX rats.

Endoscopic retrograde cholangiopancreatography after laparoscopic Roux-en-Y gastric bypass: a case series and review of the literature.

Endoscopic retrograde cholangiopancreatography (ERCP) has become an important tool in the diagnosis and treatment of pancreaticobiliary pathology. ERCP in patients that have undergone Roux-en-Y gastric bypass (RYGB) is particularly challenging because traditional transoral endoscopy may be limited. We present our experience with ERCP after RYGB and review the literature.

Do hybrid simulator-generated metrics correlate with content-valid outcome measures?

Background: Hybrid simulators provide objective metrics for laparoscopic task performance. This study aimed to evaluate the correlation between hybrid simulator-generated metrics and content-valid outcome measures.

Methods: Residents underwent training with a previously validated 5-task simulation model (5-TSM).

The impact of sleep deprivation on product quality and procedure effectiveness in a laparoscopic physical simulator: a randomized controlled trial.

Background: To compare the impact of sleep deprivation after 24-hour duty (post-call) with that of 8-hour work (post-work) on product quality (PQ) and procedure effectiveness (PE) in a laparoscopic physical simulator.

Methods: Voluntary surgeons and nurses were pretested with the Epworth Sleepiness Scale (ESS) and Minimally Invasive Surgical Trainer-Virtual Reality (MIST-VR). Surgical task was suturing perforated ulcer on a foam stomach in a physical simulator.
