Doppler-guided hemorrhoidal laser procedure for the treatment of symptomatic hemorrhoids: experimental background and short-term clinical results of a new mini-invasive treatment.

Background: According to the "vascular" theory, arterial overflow in the superior hemorrhoidal arteries would lead to dilatation of the hemorrhoidal venous plexus. A 980-nm diode laser-pulsed shot causes shrinkage of tissue. The depth of shrinkage can be regulated by the power and duration of the laser beam.

Conservative management of a spleen trauma using radiofrequency.

Aim Of The Study: Conservative operative management of a splenic injury has become more and more employed in order to preserve the immune function of the organ.

Case Report: A case of a rupture of the spleen successfully treated with the use of a radiofrequency thermal energy generator is eported. The parenchymal tear was coagulated by a one cooled tip needle electrode.
