Practical hints for hemostasis in laparoscopic surgery.

With the developments achieved in recent years in laparoscopic surgery, the field has acquired a host of new techniques to achieve haemostasis, allowing the surgeon to tackle complex procedures. These techniques include physical modalities (as simple as compression or suturing and as sophisticated as endovascular staples), thermal modalities (such as bipolar coagulation, laser or ultrasonic dissectors), and topical sealants (e.g.

Technology insight: radioguided sentinel lymph node dissection in the staging of prostate cancer.

Pelvic lymph node dissection is the only reliable method of staging for clinically localized prostate cancer. Despite the obvious prognostic advantages conferred by accurate staging, pelvic lymph node dissection is associated with significant morbidity and prolonged operative time. A substantial decrease in the sensitivity to lymph node metastasis occurs by simple reduction of the dissection area to the obturator fossa.
