The usefulness and safety of the introducer technique using a bumper-button-type device as compared with the pull method for percutaneous endoscopic gastrostomy.

Purpose: To describe our initial experiences with the standardized introducer technique for percutaneous endoscopic gastrostomy and to compare clinical outcomes and complications with the pull technique.

Methods: The introducer technique was used on 91 patients. The clinical outcomes of procedures were retrospectively collected and compared with those of 22 patients who had procedures using the pull technique.

Pringle maneuver induces hepatic metastasis by stimulating the tumor vasculature.

Background/aims: The Pringle maneuver is traditionally used to avoid hemorrhage during hepatectomy for hepatic metastasis. However, metastasis can occur under ischemic conditions due to some unknown mechanism.

Methodology: An orthotopic model of murine colon cancer was established in syngeneic BALB/c mice.
