Biliopancreatic diversion with duodenal switch and single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) are technically demanding hypo-absorptive bariatric procedures. They are often indicated in superobese patients (BMI ≥ 50 kg/m2), as robotic platform could improve ergonomics against a thick abdominal wall, preventing bending of instruments and simplifying hand-sewn anastomoses. We aimed to report our experience with robotic SADI-S (R-group) and to compare outcomes with the laparoscopic (L-group) approach. Among 2143 patients who underwent bariatric procedures at our institution between July 2016 and June 2021, 116 (5.4%) consenting patients were scheduled for SADI-S as primary or revisional procedure: 94 L-group, 22 R-group. R-group and L-group patients were matched using PSM analysis to overcome patients selection bias. Postoperative complications, operative time (OT), post-operative stay (POS) and follow-up data were compared. After PSM, 44 patients (22 patients for each group) were compared (Chi-square 0.317, p = 0.985). Median age, gender, median BMI, preoperative rates of comorbidities, previous abdominal bariatric and non-bariatric surgeries and type of surgical procedures (SADI-S/SADI) were comparable. Median OT was shorter in the L-group (130 Vs 191 min, p < 0.001). 30-days’ re-operative complications and late complications rates were comparable. At 25-months’ mean follow-up, the median Percentage Excess Weight Loss (72%) was comparable between the groups (p = 0.989). L-group and R-group were comparable in terms of re-operative complication rate and short-term outcomes. The robotic platform may increase the rate of single step procedure in challenging cases. Larger studies with longer follow-up and cost-analysis are necessary to draw definitive conclusions.

Background: Partial adrenalectomy (PA) is an alternative option to total adrenalectomy for the treatment of hereditary pheochromocytoma (PHEO) to preserve cortical function and avoid life-long steroid replacement. The aim of this review is to summarize current evidence in terms of clinical outcome, recurrence, and corticosteroid therapy implementation after PA for MEN2-PHEOs. Material and Methods: From a total of 931 adrenalectomies (1997–2022), 16 of the 194 patients who underwent surgical treatment of PHEO had MEN2 syndrome. There were six patients scheduled for PA. MEDLINE®, EMBASE®, Web of Science, and Cochrane Library were searched for English studies from 1981 to 2022. Results: Among six patients who underwent PA for MEN2-related PHEO in our center, we reported two with bilateral synchronous disease and three with metachronous PHEOs. One recurrence was registered. Less than 20 mg/day Hydrocortison therapy was necessary in 50% of patients after bilateral procedures. Systematic review identified 83 PA for MEN2-PHEO. Bilateral synchronous PHEO, metachronous PHEO and disease recurrence were reported in 42%, 26%, and 4% of patients, respectively. Postoperative steroid implementation was necessary in 65% of patients who underwent bilateral procedures. Conclusions: PA seems to be a safe and valuable option for the treatment of MEN2-related PHEOs, balancing the risk of disease recurrence with the need for corticosteroid therapy.

Extent of thyroidectomy for papillary thyroid carcinoma is still matter of debate. Indeed, recently, international guidelines endorsed thyroid lobectomy as initial surgical approach for low risk, small medium-sized (T1-T2), N0 papillary thyroid carcinoma in absence of extrathyroidal extension. When dealing with a conservative surgery for oncologic disease is of utmost importance to exclude effectively more advanced disease, which could benefit from a more aggressive initial operation. However, in the setting of surgery for papillary thyroid carcinoma, despite an accurate preoperative work up could led to identify some suspicious characteristics as macroscopic evidence of multifocality or extrathyroidal extension, and/or evidence of lateral neck lymph node metastases, it is difficult to reliably assess the central neck nodal status both pre- and intra-operatively. Frozen section examination of the central neck nodes ipsilateral to the side of the tumor has been proposed in patients scheduled for thyroid lobectomy, in order to modulate the extension of both thyroidectomy and central neck dissection. Future molecular and genetic evidences are needed to establish high-risk patients with small papillary thyroid carcinoma in which thyroid lobectomy could be not and adequate surgical treatment.

Conventional open thyroidectomy is still considered the gold standard for thyroid surgery. Transoral endoscopic thyroidectomy vestibular approach (also known as TOETVA) is often considered to be more advantageous than the other approaches, such as minimally invasive video assisted thyroidectomy, thyroidectomy via breast/axillary/retroauricular access, bilateral axillo-breast approach and axillo- bilateral breast approach. In this scoping review, we discuss the risks and the benefits of this surgical approach and its medico- legal and ethical implications, particularly focusing on the importance of practice on cadavers. Currently, there is little scientific evidence supporting TOETVA, since there are few papers on the comparison with the traditional open thyroidectomy that have been published and thus little data on the long-term outcomes of TOETVA are available. Since the better cosmetic outcome currently represents the main indication for this surgical technique, substantial medico- legal and ethical issues arise. Moreover, practice on cadavers can help surgeons to develop the technical and non-technical skills required to perform efficiently and safely this new surgical procedure.

Adrenal masses are a frequent finding in clinical practice. Many of them are incidentally discovered with a prevalence of 4% in patients undergoing abdominal anatomic imaging and require a differential diagnosis. Biochemical tests, evaluating hormonal production of both adrenal cortex and medulla (in particular, mineralocorticoids, glucocorticoids and catecholamines), have a primary importance in distinguishing functional or non-functional lesions. Conventional imaging techniques, in particular computerized tomography (CT) and magnetic resonance imaging (MRI), are required to differentiate between benign and malignant lesions according to their appearance (size stability, contrast enhanced CT and/or chemical shift on MRI). In selected patients, functional imaging is a non-invasive tool able to explore the metabolic pathways involved thus providing additional diagnostic information. Several single photon emission tomography (SPET) and positron emission tomography (PET) radiopharmaceuticals have been developed and are available, each of them suitable for studying specific pathological conditions. In functional masses causing hypersecreting diseases (mainly adrenal hypercortisolism, primary hyperaldosteronism and pheochromocytoma), functional imaging can lateralize the involvement and guide the therapeutic strategy in both unilateral and bilateral lesions. In non-functioning adrenal masses with inconclusive imaging findings at CT/MR, [18F]-FDG evaluation of tumor metabolism can be helpful to characterize them by distinguishing between benign nodules and primary malignant adrenal disease (mainly adrenocortical carcinoma), thus modulating the surgical approach. In oncologic patients, [18F]-FDG uptake can differentiate between benign nodule and adrenal metastasis from extra-adrenal primary malignancies.

Purpose: Biliopancreatic diversion with duodenal switch and single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) are technically demanding hypo-absorptive bariatric procedures generally indicated in super-obese patients (BMI ≥ 50 kg/m2). Data from the literature prove the procedure to be safe and effective, with promising bariatric and metabolic effects. Anyway, international societies support the creation of multicentric national and international registries to obtain more homogeneous data over the long period. We aimed to report our experience with this procedure. Methods: Among 2313 patients who underwent bariatric procedures at our institution, between July 2016 and August 2021, 121 (5.2%) consenting patients were scheduled for SADI-S as primary (SADIS) or revisional procedure after sleeve gastrectomy (SADI) (respectively 87 and 34 patients). Early and late post-operative complications, operative time, post-operative stay, and follow-up data were analyzed. Results: Overall, the median preoperative BMI was 52.3 (48.75–57.05) kg/m2 with a median age of 44 (39–51) years, the median operative time was 120 (100–155) min. Complications at 30th-day post-op were registered in 4 (3.3%) patients and late complications in 4 (3.3%) patients. At a median follow-up of 31 (14–39) months, the median percentage excess weight loss was 79.8 (55.15–91.45)%, and the median total weight loss was 57.0650 (43.3925–71.3475)%. Conclusion: Our data, coherently with the literature, confirm that SADI-S is a safe, effective procedure with acceptable complications rate. Larger studies with longer follow-ups are necessary to draw definitive conclusions.

Background: Comparative studies among protocols for the management of post-total thyroidectomy (TT) hypocalcemia are lacking. We compared the effectiveness of PTH-driven selective supplementation (PD-SS) and routine calcium and calcitriol supplementation with preoperative calcitriol administration in preventing symptomatic hypocalcemia (SH) and readmission. Methods: Three-hundred consecutive patients undergoing TT were assigned to 3 groups: the PD-SS group, the high-dose routine supplementation (HD-RS) group and the low-dose routine supplementation (LD-RS) group. Results: Mean post-operative stay was shorter in HD-RS patients when compared to PD-SS and LD-RS (p < 0.001). Significantly more patients in the PD-SS group experienced SH (p = 0.042). The rate of post-operative hypocalcemia was not significantly different among the groups (p = 0.063). No readmission for SH or hypercalcemia occurred. Conclusions: HD-RS emerged as the most effective treatment to prevent SH, without increasing the risk of readmission for calcitriol-related hypercalcemia. Basing on the present results, HD-RS should be recommended as the preferable protocol.

The surgical treatment of the intermediate-risk DTC (1–4 cm) remains still controversial. We analyzed the current practice in Italy regarding the surgical management of intermediate-risk unilateral DTC to evaluate risk factors for recurrence and to identify a group of patients to whom propose a total thyroidectomy (TT) vs. hemithyroidectomy (HT). Among 1896 patients operated for thyroid cancer between January 2017 and December 2019, we evaluated 564 (29.7%) patients with unilateral intermediate-risk DTC (1–4 cm) without contralateral nodular lesions on the preoperative exams, chronic autoimmune thyroiditis, familiarity or radiance exposure. Data were collected retrospectively from the clinical register from 16 referral centers. The patients were followed for at least 14 months (median time 29.21 months). In our cohort 499 patients (88.4%) underwent total thyroidectomy whereas 65 patients (11.6%) underwent hemithyroidectomy. 151 (26.8%) patients had a multifocal DTC of whom 57 (10.1%) were bilateral. 21/66 (32.3%) patients were reoperated within 2 months from the first intervention (completion thyroidectomy). Three patients (3/564) developed regional lymph node recurrence 2 years after surgery and required a lymph nodal neck dissection. The single factor related to the risk of reoperation was the histological diameter (HR = 1.05 (1.00–1-09), p = 0.026). Risk stratification is the key to differentiating treatment options and achieving better outcomes. According to the present study, tumor diameter is a strong predictive risk factor to proper choose initial surgical management for intermediate‐risk DTC.

Background: Thyroid lobectomy is the preferred option for small, unifocal papillary thyroid carcinoma. Involvement of the central neck lymph nodes is an indication for total thyroidectomy plus central neck dissection. We aimed to verify if frozen section examination of ipsilateral central neck nodes can identify the subgroup of patients scheduled for thyroid lobectomy intraoperatively who could benefit of more extensive initial operative treatment. Methods: Ninety-four consenting patients with clinically unifocal cN0 papillary thyroid carcinoma underwent thyroid lobectomy plus ipsilateral central neck dissection with frozen section examination. If the frozen section examination was positive for metastases, a completion thyroidectomy and a bilateral central neck dissection were accomplished during the same procedure. Results: Frozen section examination identified occult nodal metastases in 25 of the 94 patients who then underwent immediate completion thyroidectomy and bilateral central neck dissection. Overall, central neck node metastases were found at final histology in 35 cases: occult micrometastases were observed in additional 9 patients and nodal metastases ≥2 mm in additional 1 patient. Conclusion: Intraoperative assessment of nodal status obtained with ipsilateral central neck dissection and frozen section examination is able to change the extent of thyroidectomy in about one-fourth of patients scheduled for thyroid lobectomy. Frozen section examination appears a safe and effective strategy to decrease the need of a second-step completion procedure and, theoretically, the risk of recurrence.

Purpose: In presence of indeterminate lesions by fine needle aspiration (FNA), thyroid cancer cannot always be easily diagnosed by conventional cytology. As a consequence, unnecessary removal of thyroid gland is performed in patients without cancer based on the lack of optimized diagnostic criteria. Aim of this study is identifying a molecular profile based on long noncoding RNAs (lncRNAs) expression capable to discriminate between benign and malignant nodules. Methods: Patients were subjected to surgery (n = 19) for cytologic suspicious thyroid nodules or to FNA biopsy (n = 135) for thyroid nodules suspicious at ultrasound. Three thyroid-specific genes (TG, TPO, and NIS), six cancer-associated lncRNAs (MALAT1, NEAT1, HOTAIR, H19, PVT1, MEG3), and two housekeeping genes (GAPDH and P0) were analyzed using Droplet Digital PCR (ddPCR). Results: Based on higher co-expression in malignant (n = 11) but not in benign (n = 8) nodules after surgery, MALAT1, PVT1 and HOTAIR were selected as putative cancer biomarkers to analyze 135 FNA samples. Cytological and histopathological data from a subset of FNA patients (n = 34) were used to define a predictive algorithm based on a Naïve Bayes classifier using co-expression of MALAT1, PVT1, HOTAIR, and cytological class. This classifier exhibited a significant separation capability between malignant and benign nodules (P < 0.0001) as well as both rule in and rule out test potential with an accuracy of 94.12% and a negative predictive value (NPV) of 100% and a positive predictive value (PPV) of 91.67%. Conclusions: ddPCR analysis of selected lncRNAs in FNA biopsies appears a suitable molecular tool with the potential of improving diagnostic accuracy.

Laparoscopic adrenalectomy (LA) is the preferred treatment option for adrenal lesions, considering the improved patients outcomes, due to the reduced postoperative morbidity and postoperative pain, the faster recovery and the shorter length of hospital stay. The widespread diffusion of robotic technology led to the development and standardization of robot-assisted approach to adrenalectomy. However, to date, no clear benefit from the use of the robot-assisted approach has been found. The higher costs remain an important drawback and limit the implementation of robot-assisted adrenalectomy (RA) programs. This review summarizes the current available data regarding RA including its operative outcomes, advantages and drawbacks in comparison with conventional LA, evaluating its cost-effectiveness.

Purpose: Pre-operative work-up and macroscopic intraoperative inspection could overlook occult central neck nodal metastases in patients with papillary thyroid carcinoma (PTC). An occult N1a status is able to change the initial risk stratification in small, clinically unifocal PTC potentially scheduled for thyroid lobectomy (TL) making total thyroidectomy (TT) the preferable option. We aimed to verified the reliability of an intraoperative management protocol based on frozen section examination (FSE) of ipsilateral central neck nodes (IpsiCND) to identify, among patients scheduled for TL, those who could benefit of a more extensive surgical resection (TT plus bilateral central neck dissection -CND-). Methods: Thirty PTC patients preoperatively classified as T1N0 underwent TL plus IpsiCND-FSE (TL-group). In case of positive FSE, TT plus bilateral CND was accomplished during the same surgical procedure. A comparative analysis was performed between TL-group and a control group (C-group), who underwent TT plus IpsiCND-FSE, matched by a propensity score analysis. Results: Nodal metastases (>2 mm) were found at final histology in 5/30 patients in the TL-group and in 6/30 in the C-group (p = 1.00). Micrometastases (≤2 mm) were retrieved in 5/30 TL-group patients and in 4/30 C-group patients (p = 1.00). Final histology staged as pN1a 10 (33.3%) patients for each group. FSE correctly identified five patients with occult nodal metastases >2 mm (16.6%) in TL-group, who underwent TT plus bilateral CND during the same surgical procedure. No permanent complications occurred. At a mean follow-up of 22.2 months, no local and/or nodal recurrence were observed. Conclusions: Intraoperative assessment of N status obtained with IpsiCND plus FSE allows for an accurate risk stratification. IpsiCND plus FSE real time modulated thyroidectomy seems a safe and effective surgical strategy reducing the need of a subsequent completion surgery and, theoretically, the risk of local recurrenc

Objective: Spontaneous thyroid gland hemorrhage is a rare event. The present retrospective study considered its clinical impact and management in a referral center. Methods: Clinical records of adult patients accessed in the last 10 years (2009-2018) in the Emergency Department of Policlinico Gemelli IRCCS were reviewed to study patients with spontaneous thyroid nodule hemorrhage. All demographic and radiologic or surgical parameters were included, with special attention to the characteristics of thyroid disease and clinical management. Results: Among the 631,129 adults who were registered during the period considered, 59 consecutive patients were included in the study. The mean age was 48.3 ± 14.3 years, with a prevalence of females. The main symptoms were acute neck pain, dyspnea, and dysphagia. All patients underwent ultrasound evaluation; computed tomography scan was performed on only 3 patients, finding one case of active intranodular bleeding requiring urgent surgery. Six patients required hospitalization; the others were discharged and referred for ambulatory endocrinology follow-up. Among them, 7 patients underwent surgery in the next 6 months, with malignant disease found in 3 cases (5.1%). Conclusion: Intrathyroidal spontaneous hemorrhage is a rare event, occurring in multinodular as well as in single-nodule thyroid disease. Although the clinical course is mostly benign, this condition should be carefully evaluated as, in rare circumstances, active bleeding could induce airway obstruction with the need for emergency surgery. Patients should be referred to endocrinology ambulatory follow-up because bleeding could arise as the first sign of malignant lesions in some cases.

Background: The continuous intraoperative nerve monitoring (CIONM) technique seems to be acknowledged as a useful tool to prevent impending nerve injury, because it constantly provides valuable real-time information. Aim of the study is to evaluate the impact of the CIONM technique on functional outcome i.e., recurrent laryngeal nerve (RLN) palsy, compared to the traditional surgical procedure. Methods: From January to December 2016, 197 patients who underwent thyroid surgery were included in this retrospective study: 94 patients had CIONM procedure and 103 traditional technique, according to the order of the operating room list. Results: A total of 8 patients showed a damage to left or right vocal cord: 3 patients after CIONM procedure, and 5 patients after traditional surgical procedure. After matching for propensity score, 188 patients were eventually considered and 7 RLN palsy were identified: 3 in CIONM and 4 in traditional surgical procedure. The analysis performed on the matched propensity score sample showed a non-significant difference between the two procedures. Conclusions: In our experience no significant differences in functional outcomes were found between the use of CIONM and the standard technique.

In the last three decades, endoscopic adrenalectomy has become the gold standard for the surgical treatment of most adrenal diseases. Gagner et al., first reported in 1992, the lateral trans-abdominal laparoscopic approach to adrenalectomy. Afterwards, several retrospective and comparative studies addressed the advantages of minimally invasive adrenalectomy specifically consistent in less postoperative pain, improved patients' satisfaction, shorter hospital stay and recovery time when compared to open adrenalectomy. The lateral transabdominal approach to the adrenals is currently one of the most widely used, since it allows an optimal comprehensive view of the adrenal region and surrounding structures, and provides and adequate working space. On the other hand, from a technical point of view, essential requirements for a successful laparoscopic adrenalectomy are an appropriate knowledge of retroperitoneal anatomy, a gentle tissue manipulation and a precise haemostasis technique in order to identify appropriately the structures of interest and avoid the troublesome 'oozing' that could complicate the surgical procedure.

PURPOSE: The diagnostic, therapeutic and health-care management protocol (Protocollo Gestionale Diagnostico-Terapeutico-Assistenziale, PDTA) by the Association of the Italian Endocrine Surgery Units (U.E.C. CLUB) aims to help treat the patient in a topical, rational way that can be shared by health-care professionals. METHODS: This fourth consensus conference involved: a selected group of experts in the preliminary phase; all members, via e-mail, in the elaboration phase; all the participants of the XI National Congress of the U.E.C. CLUB held in Naples in the final phase. The following were examined: diagnostic pathway and clinical evaluation; mode of admission and waiting time; therapeutic pathway (patient preparation for surgery, surgical treatment, postoperative management, management of major complications); hospital discharge and patient information; outpatient care and follow-up. RESULTS: A clear and concise style was adopted to illustrate the reasons and scientific rationales behind behaviors and to provide health-care professionals with a guide as complete as possible on who, when, how and why to act. The protocol is meant to help the surgeon to treat the patient in a topical, rational way that can be shared by health-care professionals, but without influencing in any way the physician-patient relationship, which is based on trust and clinical judgment in each individual case. CONCLUSIONS: The PDTA in thyroid surgery approved by the fourth consensus conference (June 2015) is the official PDTA of U.E.C. CLUB.
