[Operative refractive correction of keratoconus with a modified Passow cautery apparatus (author's transl)].

The thermokeratoplasty was developed by Gasset for treatment of keratoconus. The flattening of the cornea is induced by heat. Indications and contra-indications are discussed. This is a report on our first 10 cases which were treated with a modified Passow-cauter. The procedure is simple and harmless and it seems to restrict the range of indications for corneal transplantation.

Laser smoke evacuator: effective removal of mutagenic cautery smoke.

Electrocautery knife smoke is mutagenic, unpleasant, and possibly a health hazard to operating room personnel. Traditional smoke removal methods have been largely ineffective during procedures that generate significant smoke with electrocautery use. A commercial laser smoke evacuation and filtration unit, available in most hospital operating rooms today, has proven highly effective in rapidly eliminating essentially all visible electrocautery knife smoke and odor during breast reductions and other "high smoke" procedures.

The use of bipolar cautery, laparosonic coagulating shears, and vascular clips for hemostasis of small and medium-sized vessels.

Advanced laparoscopic surgery requires a reliable method of hemostasis. In order to determine the efficacy of common hemostatic devices, we tested bipolar electrosurgery (BPES), laparosonic coagulating shears (LCS), and vascular clips (VC) on arteries of various sizes to compare the strength of hemostasis against elevated intraarterial pressure. The procedures were performed on a porcine model through a laparotomy. Segments of visceral arteries were isolated and cannulated with an angiocatheter that was linked to a pressure monitor. After hemostasis with the tested instrument and division of the vessel, the intraarterial pressure was elevated by infusion of saline solution through the angiocatheter. The pressure was recorded when bleeding occurred through the cut end of the vessel or when the pressure reached 300 mm Hg. All three devices were effective in maintaining hemostasis on small (diameter, 0.25-0.5 mm) and medium-sized arteries (diameter, 2-3.5 mm) with a success rate ranging between 75% and 100% (p = n.s.). Practice and technical finesse were required with the use of the LCS and BPES before excellent results could be obtained. The LCS has an advantage over BPES because it allows the surgeon to perform hemostasis and division simultaneously, thus keeping the operating field clean and avoiding instrument adhesion to the tissue.
