Ultrasonic Technology Facilitates Minimal Access Thyroid Surgery,

THE LARYNGOSCOPE, Issue 6 2006
David J. Terris MD
Abstract Objectives: Options for controlling the vasculature during thyroid surgery include suture ligatures, vessel clips, and bipolar cautery. Ultrasonic technology represents an alternative to conventional techniques in which the vessels are simultaneously sealed and divided. We sought to determine the safety and efficacy of thyroidectomy with ultrasonic technology. Design: Nonrandomized, prospective analysis of a series of patients undergoing thyroidectomy at the Medical College of Georgia. Methods and Materials: The records of 51 consecutive patients who underwent thyroid surgery between December 2004 and June 2005 were reviewed. Patients in whom ultrasonic technology (Harmonic-ACEÔ, Ethicon Endo-Surgery, Cincinnati, OH) was used comprised the study population. Results: Forty-four of 51 patients underwent thyroidectomy with the assistance of ultrasonic technology. There were 4 males and 40 females with a mean age of 43.5 ± 15.8 years. Twenty-two patients had a total thyroidectomy, 18 underwent unilateral lobectomy, and 4 underwent completion thyroidectomy. The overall mean incision length was 5.0 ± 2.6 (range 2,12) cm. A subgroup of patients underwent minimally invasive video-assisted thyroidectomy (n = 13) and had a mean incision length of 29.3 ± 0.8 mm. There were no cases of permanent injury to the recurrent laryngeal nerve and no cases of persistent hypoparathyroidism. Blood loss ranged from 5 mL to 100 mL, with a mean of 26.7 ± 21.8 mL. Conclusions: Ultrasonic technology facilitates thyroid surgery, particularly when a minimally invasive approach is undertaken. It reliably seals and divides the thyroid vasculature and will likely replace other methods of managing the thyroid blood supply. [source]

Minimal access thyroid surgery: technique and report of the first 25 cases

Background: Minimal access thyroid surgery, using various techniques, is increasingly being reported. The present study reviews our experience with thyroid surgery using a lateral focused mini-incision approach, and assesses its safety and feasibility. Methods: The study group comprised all patients undergoing minimal access thyroid surgery (MATS) during the period May 2002,May 2003. Data were prospectively gathered, including patient demographics, indication for surgery, operation performed, nodule size, final pathology, and complications. Exclusion criteria for this procedure included: family history of thyroid cancer, previous neck irradiation or surgery, carcinoma on fine needle aspiration, presence of significant thyroiditis, multinodular goitre, and nodule size >3 cm. The operation was carried out through a 2.5-cm lateral incision placed directly over the nodule, with exposure gained by dissecting the plane between the sternomastoid muscle and the lateral edge of the strap muscles. Results: Twenty-five patients underwent MATS, 22 women and three men. Nineteen patients underwent hemithyroidectomy, five underwent isthmectomy, and one underwent local nodule excision. The average measured incision size was 2.63 cm at the end of the procedure. The average nodule size was 2.2 cm, and the average thyroid lobe resected measured 4.7 cm in maximal length. Final pathology revealed benign nodules in 21 patients and four thyroid cancers (two follicular and two papillary). There was one wound infection and two patients had temporary recurrent laryngeal nerve neuropraxia. Conclusion: Minimal access thyroid surgery is a safe and feasible alternative to open thyroid surgery in selected cases. [source]

Minimally Invasive Thyroidectomy: Basic and Advanced Techniques

THE LARYNGOSCOPE, Issue 3 2006
David J. Terris MD
Abstract Objective: Minimal access surgery in the thyroid compartment has evolved considerably over the past 10 years and now takes many forms. We advocate at least two distinct approaches, depending on the disease process and multiple patient factors. The technical aspects are explored in depth with liberal use of videographic demonstration. Methods: The authors conducted a comparison of two distinct surgical techniques with photographic and videographic documentation of two distinct minimal access approaches to the thyroid compartment termed minimally invasive thyroidectomy (MITh) and minimally invasive video-assisted thyroidectomy (MIVAT). Both historic and previously unpublished data (age, gender, pathology, incision length, and complications) are systematically analyzed. Results: Patients who underwent minimally invasive thyroidectomy (n = 31) had a mean age of 39.4 ± 10.7 years; seven were male and 24 were female. The most common diagnosis was follicular or Hürthle cell adenoma (29%), followed by papillary or follicular cancer (26%). The mean incision length was 4.9 ± 1.0 cm. One patient developed a hypertrophic scar and one patient developed thrombophlebitis of the anterior jugular vein. There were 14 patients in the MIVAT group with a mean age of 43.7 ± 11.4 years; one was male and 13 were female. The majority of patients had follicular adenoma (42.9%) or papillary carcinoma (21.4%) as their primary diagnosis. The mean incision length was 25 ± 4.3 mm (range, 20,30 mm), and there were no complications. Conclusions: Two distinct approaches to minimal access thyroid surgery are now available. The choice of approach depends on a number of patient and disease factors. Careful patient selection will result in continued safe and satisfactory performance of minimally invasive thyroid surgery.
