Comparison of surgical completeness in patients operated on conventional open total thyroidectomy (OT) or trans-axillary robot-assisted total thyroidectomy (RATT) by a single axillary approach.

Trans-axillary robot-assisted total thyroidectomy (RATT) is nowadays worldwide accepted but the completeness obtained by RATT is still debated. The Aim of this study was to compare the completeness and safety of RATT with conventional open thyroidectomy (OT). We enrolled patients with nontoxic multinodular goiter, cytologically indeterminate nodules and well differentiated thyroid cancer without local and/or distant metastasis. In all cases the biggest nodule should be < 6 cm. The surgical completeness was evaluated by means of serum thyroglobulin (hs-Tg) and neck ultrasound (nUS) performed three months postoperatively. 100 patients underwent either RATT or OT. The type of surgical procedure was chosen by patients. They were then divided in two subgroups based on benign or malignant histology. There were no significant differences in the postoperatively values of hs-Tg in patients operated with RATT or OT, both in benign and malignant subgroups. The post-operative thyroid remnant volume estimated by nUS was not significantly different between the two groups, both in benign and malignant subgroups. We also analyzed the difference of the volume of the thyroid remnant ipsilateral to the axillary access vs that of the remnant on the contralateral side and there was not significantly difference in both subgroups. RATT was demonstrated to determine a comparable surgical completeness as OT, both in benign and malignant thyroid diseases, with no differences in the prevalence of surgical complications. In our hands the surgical completeness of RATT by a single trans-axillary was satisfying.

Genital Sensitivity and Perceived Orgasmic Intensity in Transgender Women With Gender Dysphoria After Gender-Affirming Surgery: A Pilot Study Comparing Pelvic Floor Evoked Somatosensory Potentials and Patient Subjective Experience.

BACKGROUND: The integrity of the neural pathways that link genital sensitive areas to the brain and the correlation with subjective sensations in transgender women with gender dysphoria after gender affirming surgery (GAS) have not been explored in detail and remain controversial, so far. AIM: To test with electrophysiology the integrity of the nervous paths after GAS, and to explore the relationship between genital sensitivity and self-perceived orgasmic intensity in transgender women after GAS. METHODS: Six patients who underwent GAS between 2016 and 2019 were enrolled in the study, and the evaluation of genital and pelvic neural pathways was performed. OUTCOMES: Genital sensory thresholds (at clitoral, vaginal, and anal sites) investigated by Somatosensory Evoked Potentials (SEP) and the intensity of orgasm (measured by a psychometric tool, the Orgasmometer) were combined to obtain an objective and subjective evaluation. RESULTS: SSEPs confirmed the integrity of the large diameter, dorsal column-lemniscus pathway subserving the genital area after GAS. Perceptual Threshold (PT) values were much lower at the neoclitoris compared to neovagina and anal sites. There was no correlation between Orgasmometer and SEP at anal and neovaginal level, while a trend was found at clitoral level. CLINICAL IMPLICATION: These findings could lead clinicians to a better understanding of postsurgical sexual life in transgender women in order to develop surgical techniques that could focus more on functional aspects of neovagina and neoclitoris. STRENGTHS & LIMITATIONS: Limitations: study very preliminary/exploratory; small number of patients; no long-term follow-up. Strengths: first assessment of sensory pelvic floor innervation in transgender women after GAS; use of objective methods; first attempt at correlating objectives findings to subjective experience of the sexual orgasm. CONCLUSIONS: Our evaluation showed that SSEPs is a good indicator of neural sensitivity, especially in neoclitoris, and that these measurements were consistent with the analysis of self-perceived orgasmic intensity.

The effect of robot-assisted transaxillary thyroidectomy (RATT) on body image is better than the conventional approach with cervicotomy: a preliminary report.

BACKGROUND: Cosmetic satisfaction is not only based on the patient's perception of the scar itself but is also related to body image self-evaluation. Cosmetic superiority of Robot-assisted transaxillary thyroidectomy (RATT) over conventional thyroidectomy (CT) has not yet been clearly demonstrated. Aim of our study was to compare body image in patients undergoing CT versus RATT. METHODS: The study included 160 (80 CT and 80 RATT) patients undergoing thyroidectomy between August 2014 and March 2018 at the Endocrine Surgery Department. The inclusion criteria were age 18 to < 60 years, female sex, thyroid volume < 30 mL, and nodule diameter < 5 cm. Scar length, operative time, and complications were analyzed. The body image questionnaire (BIQ) was used 3 months postoperatively. The Student t test was used for statistical analysis. RESULTS: Age was lower in RATT group (38.2 vs 41.4 years) (P < 0.0001). The nodule diameter was larger in RATT group (27.1 vs 23.1 mm) (P = 0.028). Operative time was longer in RATT group (93.7 vs 47.6 min) (P < 0.0001). The scar was longer in RATT group (59.9 vs 37.7 mm) (P < 0.0001). The groups had similar complication rates. BIQ showed that RATT patients answered more favorably to question 2, "Do you feel the operation has damaged your body?" (P = 0.042) and to question 3, "Do you feel less attractive as a result of your treatment?" (P = 0.024). Also self-global satisfaction was better in RATT group (P = 0.019). CONCLUSIONS: In our experience, RATT has a significantly better impact on body image than the conventional approach.

Minimally invasive video-assisted thyroidectomy (MIVAT).

BACKGROUND: Minimally invasive video-assisted thyroidectomy (MIVAT) was first described in 1999 and it has become a widespread technique performed worldwide. Although initially limited to benign thyroid nodules, MIVAT was progressively adopted for all types of thyroid diseases, while remaining within the selection criteria. It is reported that, in selected cases, MIVAT is comparable to standard open thyroidectomy (SOT) in terms of oncologic radicality, time, costs and complications rate, with the advantage of a better cosmetic result and a lower post-operative pain. METHODS: The authors conducted a retrospective analysis about patients who underwent MIVAT between 1998 and 2019 in the Endocrine Surgery Unit of the University Hospital in Pisa. Indications and contraindications are mentioned and strictly followed. RESULTS: Total thyroidectomy was performed in 1,862 cases (69%) and hemithyroidectomy was performed in 763 cases (28.3%). Conversion occurred in 43 cases (1.6%). In 188 cases (7%) a postoperative transient hypoparathyroidism was reported, whereas definitive hypoparathyroidism was reported in 12 cases (0.4%). Thirty-eight patients (1.4%) suffered from a definitive postoperative recurrent laryngeal nerve palsy. No definitive bilateral recurrent laryngeal nerve palsy occurred. CONCLUSIONS: From our multi-years' experience which spreads over 20 years, we can reaffirm the concept that MIVAT is a safe procedure which is not burdened by an increase complications rate or additional costs. Furthermore, this technique offers advantages in terms of cosmetic results and post-operative pain.

Male-to-Female (MtoF) gender affirming surgery: Modified surgical approach for the glans reconfiguration in the neoclitoris (M-shape neoclitorolabioplasty).

PURPOSE: The aim of this article is to describe our modified surgical technique for the reconfiguration of the glans in the clitoris and the labia minora, known as the "M-shape neoclitorolabioplasty". METHODS: The glans with all its neurovascular bundle is isolated from the corpora cavernosa, incised in Y-shape mode and spread in order to obtain an M-shape glandular flap. The "belly" of the M-shape glans will constitute the triangular neoclitoris meanwhile the lateral flaps will constitute the labia minora. The inferior apex of the neoclitoris is fixed to the superior apex of the previously spatulated urethra. The two glans flaps are incised transversally to increase their length and sutured to the sides of the spatulated urethra forming the labia minora. Our technique permits to create an aesthetically pleasing neovagina preserving all the glandular erogenous sensitivity. RESULTS: 94 patients have been treated with our modified technique of male-to-female (MtoF) gender affirming surgery. At median follow-up of 27.57 months, 81 (86.1%) patients reported vaginal intercourse and 78 (82.9%) patients referred presence of erogenous sensitivity during dilatations, intercourse or masturbations. All the glandular tissue is preserved and reconfigured forming the neoclitoris and the labia minora. The M-shape reconfiguration permit to create an aesthetically pleasant neoclitoris. CONCLUSIONS: This technique could be applied safely and easily to patients undergoing gender affirming surgery, allowing the creation of a neovagina with the best possible erogenous sensitivity without losing aesthetical results.

Systematic review of studies reporting perioperative and functional outcomes following male-to-female gender assignment surgery (MtoF GAS): a call for standardization in data reporting.

INTRODUCTION: The aim of this study is to accomplish a systematic review on the surgical techniques available for male-to-female gender assignment surgery (MtoF GAS) published in the last 15 years, from January 2002 to May 2017, assessing advantages and disadvantages. EVIDENCE ACQUISITION: A specific search on MEDLINE, Scopus and Web of Science databases included vaginoplasty for gender exchange. Preoperative (age, gender, body mass index, prior surgery), intraoperative (mean operating time, intraoperative complications, transfusion rate, conversion rate), postoperative (hospital stays, readmission rate, early and late complication rate), postoperative sexual activity, subjective satisfaction, vaginal depth, and long-term outcomes (vaginal stenosis, prolapse, dyspareunia and labial abscess) data of vaginoplasty for sexual exchange were collected. 29 articles were included (2.402 patients). EVIDENCE SYNTHESIS: Out of the 29 papers, 19 studies assessed penile skin inversion and 10 evaluated intestinal vaginoplasty. No comparative studies were found. Penile skin inversion vaginoplasty reported slightly shorter operative time compared to intestinal vaginoplasty (109-420 vs 145-420 minutes). Intraoperative complications for penile skin inversion vaginoplasty not exceeded an incidence of 10%. No significant differences in terms of postoperative complications or hospitalization time were reported. Intestinal vaginoplasty provides a deeper neovagina. Female Sexual Function Index score was significantly higher in patients undergoing intestinal vaginoplasty. CONCLUSIONS: A standardized data collection may allow a better understanding of effectiveness and outcomes of different techniques.

Prevention and management of bleeding in thyroid surgery.

Post-thyroidectomy neck hematoma represents a major concern for surgeons because it can result in severe and even life-threatening complications. In fact, postoperative hemorrhage may result in airway compression and respiratory distress, and therefore, effective hemostasis is an important goal in thyroid surgery. Postoperative hematoma occurs at a rate of approximately 0.1% to 1.1%. Almost all cases occur in the first 6 h after surgery and can be the result of several surgeon or patient factors. For many years the clamp-and-tie technique has been the most common way to divide the main vascular pedicles of the thyroid gland. Alternatively, bipolar electrocautery has been used for only very small vessels. Other hemostatic systems have been introduced and proved to be potentially very useful in neck surgery and, in particular, for thyroid surgery. This new class of instruments is generally known as "energy devices" because they use different forms of energy, such as advanced bipolar (LigaSureTM Small Jaw Medtronic, Covidien product, Mineapolis, MN, USA) and ultrasound (Harmonic Focus; Ethicon, Johnson and Johnson, Cincinnati, OH, USA), and hybrid devices that join these two technologies (Thunderbeat by Olympus, Japan). Although they all generate a significant elevation of temperature in the tissues, as in any form of energy, the temperatures reached by these instruments are never as high as the standard monopolar electrocautery. For small bleeding very close to critical structures, where energy devices are too dangerous to be used and clamp and tie is not possible, several studies have assessed the use of adjunctive hemostatic agents. In conclusion, all energy devices have been shown to significantly decrease operative times without increasing costs or complications. Adjunctive hemostatic agents have shown equivalent differences when added to standard methods from a clinically significant perspective.

Track Recurrence After Robotic Transaxillary Thyroidectomy: A Case Report Highlighting the Importance of Controlled Surgical Indications and Addressing Unprecedented Complications.

BACKGROUND: Robot-assisted transaxillary thyroid surgery (RATS), widely accepted and used in Asian countries, can be an appealing treatment option both for patients with major concerns regarding a cervical scar and for their surgeons. Patients benefit from scarless neck surgery, while their surgeons benefit from improved dexterity and ergonomics compared with remote-access endoscopic thyroid surgery. However, validating any novel surgical procedure for thyroid pathology should be based on evidence regarding its feasibility, radicality, and safety compared to the time-honored, safe and effective, conventional open thyroidectomy. It should also be evaluated for potential risks that are not present with conventional approaches. PATIENT FINDINGS: This study reports a patient with surgical track and cervical nodal recurrence, and distant metastasis following a two-stage robot-assisted surgery, and radioactive iodine ablation therapy for a papillary thyroid carcinoma that was initially regarded a single indeterminate nodule. SUMMARY: This case emphasizes the importance of thoroughly evaluating the oncological safety of RATS, and points out the possibility of "malignant seeding along the surgical access" being an untraditional potential complication associated with the procedure. CONCLUSIONS: While tailoring the surgical strategy to the patients' concerns and desires is important, adhering to fundamental onco-surgical principles is a priority. Furthermore, unconventional complications associated with novel surgical procedures should be properly evaluated and addressed.

Video-assisted surgery for thyroid cancer patients.

BACKGROUND: Today is well known that endoscopic thyroidectomy could reach the same level of completeness as a conventional operation. We have been using minimally invasive video assisted thyroidectomy (MIVAT) as our favorite minimally invasive access to thyroid diseases from the late nineties. METHODS: Our experience with MIVAT is represented by 2,413 cases between 1998 and 2014: in particular 821 patients were operated with a total thyroidectomy for a papillary carcinoma (34.0%). Furthermore 967 patients underwent a MVAT for the presence of an undetermined lesion (40.0%). RESULTS: The conversion rate was very low: 24 patients (1.0%), mainly due to: unexpected posterior tracheal invasions (nine patients), involvement of lymph nodes not evident at echography (four patients), esophageal infiltration (three patients), strap muscles infiltration (three patients) and finally in five cases the presence of serious thyroiditis that had escaped to ultrasonographic evaluation. CONCLUSIONS: The minimally MIVAT to treat malignant thyroid tumors has today a very clear indication for malignancies.

The impact of the Harmonic FOCUS™ on complications in thyroid surgery: a prospective multicenter study.

In recent years, newer tools have been developed and used in thyroid surgery. This study compared patients with multinodular goiter undergoing thyroidectomy using the Harmonic FOCUS™ with patients undergoing the clamp-and-tie technique. Medical records of 268 patients with multinodular goiter undergoing thyroidectomy from December 2006 to July 2011 in two centers in Italy, the Department of Surgery of Pisa and the General Surgery Unit of Grosseto, were prospectively evaluated. Patients were divided into group A (Harmonic FOCUS™ Shear), and group B (clamp-and-tie technique). Patient demographics and specific end points analyzed included age, sex, diagnosis, thyroid gland volume, operative time, complications, need for clips and hemostatic agents, need for suction balloon, postoperative blood loss, and postoperative hospital length of stay. 141 patients were included in group A, and 127 patients were included in group B. The two groups were similar in age, sex ratio, indication for surgery, and thyroid volume. Mean operative time was significantly shorter with the Harmonic FOCUS™ Shear (51.8 min) than with the clamp-and-tie technique (70.9 min). The mean postoperative amount obtained from the suction balloon was similar. Vascular clips were needed significantly more frequently in group A (26.2 %) than in group B (12.5 %), whereas the need for hemostatic agents was significantly reduced in group A (4.2 %) compared with group B (14.9 %). The decision to leave a suction drain at the end of the operation occurred significantly more frequently in group B (96 %) than in group A (78 %). Mean postoperative hospital length of stay was 2.02 days in group A compared with 3.1 days in group B, which was significant. No definitive postoperative complications were documented in either group, except a higher rate, but not statistically significant, of permanent hypoparathyroidism in group B versus Group A. Transient laryngeal nerve injury was similar in both groups, whereas transient hypoparathyroidism occurred more frequently in Group B (4.7 %) than in Group A (2.4 %). Harmonic FOCUS device was significantly associated with lower rate of postoperative transient hypocalcemia, decreased operative time, shorter hospitalization, and lesser need for hemostatic agents and postoperative drain balloon. These results might be considered "indirect" money-saving factors, despite the cost of the device, especially in countries where the cost of thyroidectomy is influenced also by the hospital length of stay.

Increased costs of perioperative risk assessment for thyroid surgery in elderly people (over 80 years) presenting with benign disease.

BACKGROUND/OBJECTIVES: Evaluate how surgical treatment of benign thyroid disease in elderly people is prone to induce an increase of costs in the next future due to the aging process of the population. METHODS: A retrospective analysis has been performed on a total of 116 patients operated between January 2007 and September 2011, divided in a group of 58 patients aged over 80 years (Group A) and 58 patients younger than 80 years (Group B). The analyzed data included age, preoperative diagnosis, severe co-morbidities, procedures other than standard needed to evaluate anaesthesiological risk, postoperative hospital stay, complications, duration of postoperative intensive care monitoring, pathologic characteristics, and costs of anaesthesiological risk assessment. RESULTS: Statistical analysis of collected data showed that the costs related to perioperative risk assessment (p value < 0.001) and the duration of hospital stay (p value < 0.001) were higher in Group A than in Group B. Instead, surgery-related complications were not statistically different. CONCLUSIONS: Despite feasibility and safety of modern surgical techniques, indications for surgery in elderly patients affected by benign thyroid disease should be reserved mainly for those patients with severe medical necessity.

Minimally invasive video-assisted thyroidectomy: an analysis of results and a revision of indications.

BACKGROUND: The first report of minimally invasive video-assisted thyroidectomy (MIVAT) was published in 1999, and the indications were progressively implemented: from cytologically undetermined thyroid nodules to intermediate-risk differentiated thyroid cancers. The aim of this study was to review the entire series of patients who underwent a MIVAT, critically analyzing its indications and contraindications and trying to figure out how the indications might be extended. METHODS: From 1998 to 2009, a total of 1,946 patients (1,659 females, 287 males; mean age = 40.2 years) underwent MIVAT in our department. Inclusion criteria were benign thyroid nodules <35 mm, malignant nodules <20 mm, and an ultrasonographically estimated thyroid volume (ETV) <25 cc. The presence of suspicious or metastatic lymph nodes and the presence of severe thyroiditis were considered a contraindication for MIVAT. RESULTS: A total thyroidectomy was performed in 1,435 patients (72.3%). A total lobectomy was performed in 511 cases (26.3%), and a central neck node sampling was associated with total thyroidectomy in 104 cases. Final histology revealed benign disease in 979 cases (51.5%) and a malignancy was diagnosed in 915 cases (48.5%). Unexpected thyroiditis was found on final histology in 17.9% of the patients with benign disease and 30.9% of patients with malignancy. The incidence of thyroiditis was significantly different in these two populations (p < 0.0001). CONCLUSION: Our data confirm the validity of the traditional indications for MIVAT: low-risk differentiated thyroid cancer (DTC), cytologically undetermined nodules, and small-volume benign thyroid disease. The indications may be further and safely extended to those patients with associated thyroiditis and those with intermediate-risk DTC. MIVAT can be proposed on a much larger scale than it was at its onset and cannot be considered an option for only a limited number of patients.
