Comparative StudyBipolar thermofusion vessel sealing system (TVS) versus conventional vessel ligation (CVL) in thyroid surgery--results of a prospective study.
One of the keystones in surgery of the thyroid gland is accurate hemostasis. This can be achieved by conventional ligations or new instruments as harmonic scissors or bipolar devices. In the present study, we report our experience with a new bipolar thermofusion vessel sealing system (TVS) compared to conventional vessel ligation (CVL). ⋯ TVS is safe with a similar complication rate as CVL. Mean operative time for total thyroidectomy is shortened with TVS.

Fournier's gangrene is a necrotizing fasciitis that affects the perineal, genital, or perianal regions. The objective of this study was to highlight this uncommon condition with a particular focus on the disease course in females. ⋯ The female gender is a risk factor for mortality in patients with Fournier's gangrene and is associated with a higher incidence of inflammation of the retroperitoneal space and abdominal cavity. Differences in male and female genital anatomy may be the reason for the rapid spread of infection to the retroperitoneum and the fatal outcome in women. Fournier's gangrene as a high-risk disease in females should attract exceeding attention.

Electromyographic response persists after peripheral transection: endorsement of current concepts in recurrent laryngeal nerve monitoring in a porcine model.
Recurrent laryngeal nerve palsy is a serious complication of endocrine surgery to the neck. Permanent lesions are still occurring in about one in a hundred, despite standardized surgical approach to the nerve and the availability of recurrent laryngeal nerve monitoring. Intraoperative recurrent laryngeal nerve monitoring is based on the visual or acoustic registration of evoked electromyography of the laryngeal muscles. Primarily, it proves conductivity of the stimulated nerve segment towards the muscle, so that stimulation distal of the lesion should show persistent electromyographic response. ⋯ This result demonstrated a remarkable pitfall for the neuromuscular monitoring at the recurrent laryngeal nerve: In the human surgical setting, this might have resulted in the false assumption of an anatomical intact nerve. The persistence of distal electromyographic conduction strengthens the proposal to stimulate the vagal nerve as the proximal portion of the nerve as a part of a systematic protocol.
