RESUMO

Background: Thyroid surgery is associated with a number of surgical complications including recurrent laryngeal nerve (RLN) injury and hypoparathyroidism. The existing methods share the same principle-the mobilization of the thyroid from the lateral side. The aim of this study was to evaluate the safety of a novel technique of thyroidectomy-tension-free thyroidectomy (TFT) based on the medial approach to the laryngeal nerves and parathyroid glands (PTGs). Methods: The study was conducted between August 2021 and July 2022 in Saint Petersburg State University Hospital. A total of 261 patients with thyroid diseases were enrolled in the study and operated on using the TFT technique. Results: The operations with the use of TFT technique were completed in all but two cases which required the conversion to the standard lateral approach. Of 259 TFT cases unilateral laryngeal paresis was registered in 6 (2.3%) cases or in 1.7% of the number of RLNs at risk. In all but one case the vocal fold function recovered in less than 6 months of the follow-up. Among 87 patients who underwent total thyroidectomy transient postoperative hypoparathyroidism was found in 10 cases (11.5%), rate of persistent hypoparathyroidism was 0%. One case of postoperative bleeding was recorded (0.4%). Conclusions: The TFT technique demonstrated high safety and several advantages over the traditional method of performing operations on the thyroid gland.

RESUMO

The safety of thyroid surgery in terms of recurrent laryngeal nerve palsy and hypoparathyroidism has increased over the last decade. In this study, we present a new method of tension-free thyroidectomy (TFT), which could be used to further decrease the complication rate after a thyroidectomy. The procedure is based on the medial approach to the recurrent laryngeal nerve and the parathyroid glands after the division of the isthmus and successive complete dissection of Berry's ligament. In total, 92 patients (127 nerves at risk) underwent "tension-free thyroidectomy" (TFT) between August and November 2021. All the procedures were performed by a single surgeon at Saint Petersburg State University Hospital. There were 74 females and 18 male patients (ratio 4.1:1) with a mean age of 46.9 (range from 17 to 74). A lobectomy was carried out in 57 (62%) patients and a total thyroidectomy in 35 (38%). In 27 cases, patients additionally underwent central and/or lateral neck dissection. Indications for surgery were papillary carcinoma (N = 34), medullary cancer (N = 2), follicular neoplasia (N = 43), Grave's disease (N = 9), multinodular toxic goiter (N = 3), and multinodular nontoxic goiter (N = 1). Mean thyroid volume was 24.6 ml (ranged 12-70 ml). Intraoperative neuromonitoring was used in all the cases (5 mA). Translaryngeal ultrasound (TLUS) or direct laryngoscopy were routinely used prior and after surgery to evaluate vocal cords mobility. Calcium and parathormone levels were measured in patients after thyroidectomy on the first, 14th and 30th postoperative days. No recurrent laryngeal nerve palsy was observed. One patient exhibited hypoparathyroidism which was resolved in 2 weeks using substitution therapy with calcium and alfacalcidol. The mean operating time for lobectomy was 54 ± 14 min (range: 30-95 min) and for total thyroidectomy 99 ± 28 min (range: 55-158 min). There was no conversion to the conventional lateral-to-medial approach. TFT can be considered a safe and feasible operation. Comparative (randomized studies) with conventional dissection technique should be performed to investigate the hypothesis that this approach can provide a lower complication rate.

RESUMO

The interest on partial adrenalectomy has steadily increased over the past twenty years. Adrenal pathologies are mostly benign, making an organ-preserving procedure attractive for many patients. The introduction of minimally invasive techniques played probably an important role in this process because they transformed a complex surgical procedure, related to the difficult access to the retroperitoneal space, into a simple operation improving the accessibility to this organ. In this review we summarize the role of partial retroperitoneoscopic adrenalectomy over the years and the current indications and technique.

RESUMO

PURPOSE: Direct flexible laryngoscopy (DFL) is the golden standard to evaluate the vocal cord (VC) function in thyroid and parathyroid surgery pre- and postoperatively. Transcutaneous laryngeal ultrasonography (TLUS) could represent an alternative to the DFL and has been evaluated in the present study comparing the results of both methods performed at two referral centers for endocrine pathologies. METHODS: In the setting of a retrospective study, 668 patients (560 female, 118 male; mean age 50.3 ± 14.2) were included from two tertiary referral centers of endocrine surgery. In all patients, TLUS was performed pre- and postoperatively prior to transnasal DFL, which served as a golden standard. TLUS was performed by B-scan (probe 5-13 MHz, aperture 40 mm). RESULTS: Preoperative visualization of the vocal cords by TLUS was possible in 526 patients (78.7%). Due to the frequent thyroid cartilage calcification (TCC) in male patients, a significant difference in the visualization rate was found between female and male (88.7% vs. 26.8%) [p < 0.0001]. Additionally, the visualization rate was inversely related to the patient's age [p < 0.001]. The sensitivity of preoperative TLUS was found to be 66.7%, the specificity 100%. DFL confirmed a postoperative palsy in 34 out of 40 patients with supposed abnormal vocal cord mobility at TLUS and demonstrated a palsy in four more cases with supposed regular mobility at TLUS. Therefore, the sensitivity of postoperative TLUS was 86%, the specificity of 99.1%, positive predictive value 89.4%, negative predictive value 98.7%. CONCLUSIONS: TLUS could represent an alternative for the evaluation of vocal cords mobility. This method has the potential to replace the DFL in the majority of cases, especially in female patients. Nevertheless, DFL is still necessary in about 20% of the patients with failed visualization at TLUS.
