Minimally invasive video-assisted thyroidectomy

BACKGROUND: In this paper we describe the results of our personal technique for minimally invasive video-assisted thyroidectomy (MIVAT). METHODS: Sixty-seven patients were selected for MIVAT. Selection criteria were nodule size less than 30 mm, thyroid volume less than 20 mL, no thyroiditis, no previous neck surgery or irradiation. The procedure, totally gasless, is carried out through a 15-mm central incision above the sternal notch. Dissection is performed under endoscopic vision, using conventional and endoscopic instruments. RESULTS: We performed 51 lobectomies and 15 total thyroidectomies. Mean operative time was 73.6 minutes for lobectomy and 109.6 minutes for total thyroidectomy. Conversion to open procedure was required twice (3%). We observed 2 cases of transient postoperative hypocalcemia and 1 case of transient recurrent laryngeal nerve palsy. The cosmetic result was considered excellent by most patients. CONCLUSIONS: MIVAT is safe and feasible. The indications are limited at present, but the results are encouraging, and we are optimistic about the future expansion of its applicability.     

Comparison between minimally invasive video-assisted thyroidectomy and conventional thyroidectomy: a prospective randomized study.

BACKGROUND: Endoscopic procedures for thyroid surgery have been introduced since 1998, but their diffusion has remained limited because their advantages were never demonstrated. METHODS: Forty-nine patients undergoing surgery for either a thyroid nodule or a small papillary carcinoma were allotted to 1 of these procedures, minimally invasive video-assisted thyroidectomy (MIVAT) or conventional thyroidectomy (CT). Exclusion criteria were nodules greater than 35 mm, presence of thyroiditis, and thyroid volume greater than 20 mL. Preoperative diagnosis, operative time, postoperative pain, complications, and cosmetic result were evaluated. RESULTS: MIVAT group included 25 patients and the CT group 24 patients. Operative time was 66 +/- 24 minutes for MIVAT and 45 +/- 15 minutes for CT (P = .001). Postoperative course was significantly less painful in the patients who underwent MIVAT (P = .003). Cosmetic result evaluated by verbal response scale and numeric scale was in favor of MIVAT (P = .003 and P = .01, respectively). One recurrent nerve palsy and 1 transient hypoparathyroidism were present in CT patients; MIVAT patients experienced 2 transient palsies. CONCLUSIONS: Despite some MIVAT advantages in terms of postoperative pain and cosmesis, CT still offers an advantage in terms of operative time and its safety should not differ. Larger series of patients are needed before deciding whether endoscopic thyroidectomy can offer important advantages.

Minimally invasive video-assisted thyreoidectomy (MIVAT) with and without use of harmonic scalpel—a randomized study

BACKGROUND AND AIMS: Minimally invasive video-assisted thyroidectomy (MIVAT) has been used for the removal of small thyroid nodules to improve cosmetic results and diminish pain. The aim of this study was to compare the outcomes of the MIVAT operations with and without the use of an ultrasonic harmonic scalpel (HS). PATIENTS AND METHODS: Seventy-six patients with a solitary thyroid nodule below 30 mm in diameter were randomized to two groups of 38 patients each. Unilateral thyroid lobectomy was performed in each patient. In the clip-ligation group (CL-G), during MIVAT, the superior thyroid vessels were clipped and bipolar coagulation was used to secure smaller vessels, whereas in the harmonic scalpel group (HS-G), HS was used to dissect and divide all the thyroid vessels. The statistical analysis included the mean operative time, blood loss, postoperative morbidity, scar length, cosmetic satisfaction at 1 and 6 months following surgery, and cost-effectiveness. RESULTS: HS-G vs CL-G operations were shorter (31.4 +/- 7.7 vs 47.5 +/- 13.2 min; p < 0.001), the mean blood loss was smaller (12.9 +/- 5.7 vs 32.8 +/- 13.0 ml; p < 0.001), the mean scar length at 1 month following surgery was shorter (15.6 +/- 1.4 vs 21.5 +/- 1.9 mm; p < 0.001), and greater cosmetic satisfaction was achieved at 1 month after surgery (88.9 +/- 9.7 vs 81.9 +/- 5.4 pts; p < 0.001), but the difference became nonsignificant at 6 months postoperatively. MIVAT with HS was 20-30 euros more expensive. No major complications were observed in both groups. CONCLUSIONS: HS in the MIVAT operations is safe and facilitates dissection, allowing for a significant decrease in operative time. Other benefits, such as lower blood loss, a scar a few millimeters shorter, or a slightly better early cosmetic result, are offered at slightly increased costs.     

Minimally Invasive Video-Assisted Thyroidectomy for Follicular Neoplasm: Is There an Advantage Over Conventional Thyroidectomy?

Background Minimally invasive video-assisted thyroidectomy (MIVAT) is safe and effective for selected patients, but its advantages are not clearly defined. Results of MIVAT for follicular neoplasms at a single institution were retrospectively evaluated to define its advantages or disadvantages. Methods Between October 2002 and May 2004, 22 patients underwent MIVAT. Twenty-six patients who underwent conventional thyroidectomy during the same time period served as matched controls. Operative times, pathologic findings, complications, analgesic requirements, and incision lengths were retrospectively evaluated. Results Four MIVAT and three conventional surgery patients underwent total thyroidectomy. Eighteen MIVAT and 23 conventional patients underwent hemithyroidectomy. The operative time (mean ± SEM) for hemithyroidectomy was 102 ± 4 minutes for MIVAT and 86 ± 3 minutes for conventional surgery (P < .05). In subgroup analysis that excluded patients with thyroiditis, operative times were not significantly different: MIVAT, 99 ± 4 minutes; conventional, 88 ± 4 minutes. The mean incision length was 2.3 ± .5 cm in the MIVAT group. Conventional thyroidectomy was performed through a 4- to 5-cm incision. The average amount of narcotic used was not significantly different (intravenous, 9.9 ± 3.1 mg [MIVAT] vs. 12.4 ± 3.8 mg; oral, 10.3 ± 4.2 mg [MIVAT] vs. 3.5 ± 2.0 mg). The conventional group received more cyclooxygenase 2 inhibitor (527 ± 9 mg vs. 187 ± 84 mg; P < .05). One patient in each group experienced transient hoarseness. There were no cases of permanent hypoparathyroidism or recurrent laryngeal nerve injury in either group. Conclusions MIVAT is as safe and effective as conventional thyroidectomy and is associated with similar narcotic analgesic requirements, but it can be performed through smaller incisions. Operative times were significantly longer for MIVAT, but when patients with thyroiditis were excluded, operative times were not significantly different.

Video-assisted thyroidectomy: indications and results

Background and aims Minimally invasive video-assisted thyroidectomy (MIVAT) was set up and introduced in our department in 1998. Its results, after an acceptable relapse, can now be evaluated, also speculating on new possible indications. Patients and methods The procedure is based on a unique incision in the central neck, 2 cm above the sternal notch, using small conventional retractors and needlescopic (2 mm) reusable instruments. Haemostasis is achieved by a harmonic scalpel. Patients, 833, underwent MIVAT since June 1998. There were 715 females and 118 males (ratio 4:1). Lobectomy was carried out in 323 (38.7%) patients, total thyroidectomy in 510 (61.2%) patients. Results Mean operative time of lobectomy was 36.2 min (range: 20–120); for total thyroidectomy, 46.1 min (30–130). Conversion to standard cervicotomy was required in 16 cases (1.9%); Operative complications were represented by transient monolateral recurrent nerve palsy in eight cases (0.9%), definitive monolateral recurrent nerve palsy in seven cases (0.8%). Twenty patients exhibited a hypoparathyroidism, which corresponds to 3.9% of total thyroidectomies performed, but only two showed permanent hypoparathyroidism (0.3%). Conclusion MIVAT can be considered a safe operation offering significant cosmetic advantages with possible new promising indications such as prophylactic thyroidectomy in rearranged during transfection (RET) gene mutation carriers. It is still limited to a minority of patients, in particular, in endemic goitre countries.

Minimally invasive video-assisted thyroid resection (MIVAT)--a well accepted operative procedure

INTRODUCTION: We report on our results of MIVAT operations. METHOD: Nineteen Patients including 15 females and 4 males were operated with MIVAT, corresponding to 11 % of all patients undergoing an operation for benign goitre in our hospital. A single node of the thyroid gland within 30 mm and enlargement of a thyroid lobe up to 25 ml were the selection criteria. The median age was 34 years (range 16-61). We performed 2 thyroidectomies, 6 Hartley-Dunhill resections, 9 hemihyroidectomies and 2 enucleations. Eighteen patients (95 %) were followed-up postoperatively. The median follow-up period was 8 months (range 1 -21). RESULTS: The median operation time was 83 min (range 60-124). The median preoperative thyroid gland volume was 25 ml (range 10-54) measured by ultrasound. The resected thyroid tissue ranged from 12 to 51 g (median 29 g). A statistical significant difference (P = 0.04 paired t-test) between the preoperative and postoperative estimated serum-calcium levels (2.31 vs. 2.25 mM) was observed. But both parameters were inside the physiological range. Paresis of the recurrent laryngeal nerve was not observed. 89 % of the patients rated the postoperative cosmetic result as very good and all patients would prefer this operation procedure once again. CONCLUSION: The MIVAT procedure is a safe operation also in small groups with excellent cosmetic results postoperatively and a high acceptance by the patients.     

An easier technique for minimally invasive video-assisted thyroidectomy

Because of the efforts of many pioneer surgeons, the minimally invasive video-assisted thyroidectomy (MIVAT) has been recognized as a safe procedure, offering advantages such as better cosmetic outcome and less analgesic need. The MIVAT technique was described in 51 selected patients in 2001. The technique was not therefore widely used because of the excess operating time compared with traditional thyroidectomy, and most importantly, this method needed a steep learning period. This study reports a modified MIVAT procedure, which can make this operation easier and shorten the time of learning. We compared the outcomes of the originally described methods with our modified method. The selection criteria for performing MIVAT were as follows: thyroid nodules in one lobe and less than 50 mm on their largest diameter, benign lesion proved by fine-needle biopsy, patient without history of thyroiditis, and no previous neck surgery or irradiation. All patients received lobectomy. Sixty patients were eligible for MIVAT during a period of 27 months. The patients were divided into two groups. Group A consisted of the 17 patients who underwent MIVAT using the original technique that was described previously. Group B consisted of the 43 patients who underwent MIVAT using a self-designed Army retractor with a mosaic ring. The mean operation time of Group A was 120 minutes and that of Group B was 59.2 minutes. The size of the incisions was no difference in either group. There were no postoperative complications except in one patient with transient recurrent laryngeal nerve palsy in Group A. There was one conversion to open thyroidectomy in Group A and none in Group B. The cosmetic results were no different between the two groups. In conclusion, the use of a modified Army retractor with a mosaic ring made the MIVAT procedure easier and offered similar advantages.     

Systematic review with meta-analysis of prospective randomized trials comparing minimally invasive video-assisted thyroidectomy (MIVAT) and conventional thyroidectomy (CT)

Background

Minimally invasive video-assisted thyroidectomy (MIVAT) has gained acceptance among surgeons as its feasibility has been well documented. The aim of this systematic review with meta-analysis has been to assess and validate the safety and feasibility of MIVAT when compared to conventional thyroidectomy (CT) and to verify other potential benefits and drawbacks.

Methods

A literature search for prospective randomized trials comparing MIVAT and CT was performed. Trials were reviewed for the primary outcome measures: overall morbidity, recurrent laryngeal nerve palsy, postoperative hypocalcemia, and postoperative hematoma; and for the secondary outcome measures: operative time, conversion to standard procedure, intraoperative blood loss, intraoperative drain insertion, nodule size and thyroid weight, postoperative pain evaluation, length of hospital stay, patient satisfactory score, and cosmetics results. Standardized mean difference (SMD) was calculated for continuous variables and odds ratio for qualitative variables.

Results

Nine prospective randomized studies comparing MIVAT and CT were analyzed. Overall, 581 patients were randomized to either MIVAT (289, 49.7 %) or CT (292, 50.3 %). The primary outcome measures of MIVAT were comparable with those of CT without statistically significant difference. Patients who underwent MIVAT experienced significantly less pain than those operated on conventionally during the whole postoperative period. Patient satisfactory score significantly favored MIVAT (9.0 vs. 6.8, SMD?=??3.388, 95 % CI?=??5.720 to ?1.057). Operative time was significantly longer in MIVAT (75.2 vs. 59.2 min, SMD?=?1.246, 95 % CI?=?0.227–2.266).

Conclusions

MIVAT is a safe and feasible alternative for the removal of small-volume benign thyroid disease and low-risk papillary thyroid carcinomas showing better cosmetics results and less postoperative pain but significantly longer operative time when compared to CT. New multicenter randomized studies are needed to evaluate the technique in more complex circumstances such as intermediate-risk thyroid cancer, lymph node removal, thyroiditis, and Graves’ disease.     

The eligibility of MIVA approach in thyroid surgery

Introduction Thyroid size, by preoperative ultrasound evaluation, is a very important criterion of minimally invasive video-assisted thyroidectomy (MIVAT) exclusion because the working space provided by the technique is limited. The aim of this work is to verify the suitability of MIVAT and its applicability in clinical practice in patients with a thyroid volume up to 50 ml. Methods From January 2003 to February 2006, 33 patients were selected for MIVAT. A completely gas-less procedure was carried out through a central skin incision performed “high” between the cricoid and jugular notch. Results The skin incision performed was from 20 to 35 mm (mean 24.88 mm ± 2.74) for different thyroid sizes. We obtained in all cases excellent results about patients cure rate and comfort, few cases of postoperative pain, and attractive cosmetic results. Conclusion In this study, we demonstrated that the MIVAT, for thyroids up to 50 ml in volume, is feasible and safe. This procedure allows more patients, who would have been excluded before, to take advantage of this minimally invasive approach with good cosmetic results, highly regarded by young female patients, and reduced paresthetic consequences.
