Vessel sealing using a pulsed bipolar system and open forceps.

We evaluated the vessel-sealing ability of one application of a pulsed plasma kinetic (PK) electrosurgical device on skeletonized vessels up to 7 mm in diameter to withstand sustained pressure of 300 mm Hg using bench and animal models. Forty-six porcine specimens and 66 abattoir vessels (112 total) were pressure tested after sealing with a pulsed PK system. Of these, 108 (96%) met the criterion of 300 mm Hg pressure held for 10 seconds without leaking. The PK system open forceps effectively closes vessels and maintains closure at a pressure level sufficient for clinical use. The device is more effective than clips, sutures, and staples.

In the management of abnormal uterine bleeding, is office hysteroscopy preferable to sonography? The case for hysteroscopy.

Office hysteroscopy for the diagnosis and management of abnormal uterine bleeding has developed into an easily performed procedure, with minimal discomfort and significantly reduced risks and expense. Miniaturization of instruments and safer liquid distention media, along with effective local analgesia, have made the procedure a fast, effective, and much more precise way to detect intrauterine abnormalities, as well as to better define the correct plan for any proposed operative management. In addition to the above, hysteroscopy is considered the "gold standard" for evaluating the uterine cavity. Numerous studies comparing hysteroscopy to sonography, with or without saline solution infusion are cited, along with other studies comparing hysteroscopy to blind biopsy and curettage, all indicating that hysteroscopy is more accurate, with fewer false-positive and false-negative results.
