    ABSTRACT: This study was conducted to compare the outcome of total thyroidectomy using the electrothermal bipolar vessel sealing system, the harmonic scalpel, and the classic suture ligation technique. This was a retrospective study of prospectively collected data from 382 consecutive total thyroidectomies from September 2004 to August 2006. Patients were divided into 3 groups: group SL patients (n = 90) underwent total thyroidectomy with the classic suture ligation technique, group L (n = 148) with the electrothermal bipolar vessel sealer, and group U (n = 144) with the harmonic scalpel. The main outcomes measured were surgical and hospitalization time, intraoperative and postoperative bleeding, postoperative hypocalcemia, and superior and inferior laryngeal nerves injuries. The 3 groups were similar in terms of demographics, thyroid gland weight and pathology, perioperative complications, and hospital stay. Compared with the classic technique, surgical time was reduced significantly by about 20% when the bipolar vessel sealer or harmonic scalpel was used (93.3 +/- 12.5 vs 74.3 +/- 14.2 and 73.8 +/- 13.8 min, P = .001, and P = .001, respectively). Both the bipolar vessel sealer and harmonic scalpel are safe, useful, and time-saving alternatives to the traditional suture ligation technique for thyroid surgery. Because no differences were observed regarding these 2 devices, the choice should be made based on the surgeon's preferences and experience.

    ABSTRACT: In this prospective observational study we present preliminary results of a modification of the translaryngeal tracheostomy technique that was introduced by Fantoni in 1997. The study was conducted in a five-bed surgical intensive care unit of a university teaching hospital. The study included 14 consecutive surgical patients (8 men, 6 women) who underwent a modified translaryngeal tracheostomy in a 6-month period. In our modification of the technique, we keep the basic principle of the inside-to-outside approach of the Fantoni technique, and combine it with a blind needle insertion, as reported in the classic subcricoid retrograde intubation technique. The technique that we use involves two medical doctors and a nurse. Mean patient age was 68.9 years (range: 31-85 years) and mean APACHE II score was 15.8 (range: 6-31). Mean operative time for the procedure was 15.2 min (range: 11.5-22 min). Eight of the patients died during the postoperative course in the ICU from causes relevant to their surgical pathology. One patient survived to be discharged from the ICU but died of an acute myocardial infraction later in the same hospital stay. Five patients survived to be discharged from the hospital. The modified translaryngeal tracheostomy seems to be as reliable and safe as the original technique. In addition, the modified technique is faster and can be performed without the use of an endoscope.

    ABSTRACT: Hemostasis in thyroid surgery is of utmost importance for a successful surgery and an uneventful postoperative course. The present article reports a single surgeon's 3-year experience in the use of the harmonic scalpel. The device was developed in the early 1990s and offered adequate and safe hemostasis for vessels up to 3 mm in width. This was a prospective observational study. Data sheets from all patients who had surgery by a single endocrine surgeon in the period from 1999 to 2004 were evaluated. Patients were divided into 3 groups based on the surgical technique used: group I comprised the conventional knot-and-tie technique, group II comprised the ligation of all but the superior thyroid vessels with a scalpel, and group III comprised patients in whom the device was used exclusively. The groups were compared in regard to surgical time, cost, and complication rate. A total of 272 patients were included in the study: 107 patients were included in group I, 77 in group II, and 88 group III. The surgical time of group I differed significantly compared with groups II and III (P < .0001 in both cases). Surgical times between groups II and III did not differ significantly (P = .701). The use of the harmonic scalpel reduces surgical time, but it increases the cost of the surgery. It is our belief that by including in the absolute cost the time saved and the reduction in human resources needed, the use of the scalpel would prove to be economic.

    ABSTRACT: A case of a large multiplex recurrent hydatid cyst involving the left gluteal muscle and the left iliopsoas, accompanied with degeneration of the musculature of the left upper leg is presented along with a review of the relevant literature. Very few such cases have been reported worldwide. The presented case is also distinguished by the involvement of muscles of distant anatomic areas.
