Abstract
OBJECTIVE To assess recurrence according to the type of surgery for primary hyperparathyroidism (pHPT) in multiple endocrine neoplasia type 1 ( MEN1 ) patients and to identify the risk factors for recurrence after the initial surgery. BACKGROUND In MEN1 patients, pHPT is multiglandular, and the optimal extent of initial parathyroid resection influences the risk of recurrence. METHODS MEN1 patients who underwent initial surgery for pHPT between 1990 and 2019 were included. Persistence and recurrence rates after less than subtotal parathyroidectomy (LTSP) and subtotal parathyroidectomy (STP) were analyzed. Patients with total parathyroidectomy with reimplantation were excluded. RESULTS Five hundred seventeen patients underwent their first surgery for pHPT: 178 had LTSP (34.4%) and 339 STP (65.6%). The recurrence rate was significantly higher after LTSP (68.5%) than STP (45%) ( P < 0.001). The median time to recurrence after pHPT surgery was significantly shorter after LTSP than after STP: 4.25 (1.2-7.1) versus 7.2 (3.9-10.1) years ( P < 0.001). A mutation in exon 10 was an independent risk factor of recurrence after STP (odds ratio = 2.19; 95% CI: 1.31; 3.69; P = 0.003). The 5 and 10-year recurrent pHPT probabilities were significantly higher in patients after LTSP with a mutation in exon 10 (37% and 79% vs 30% and 61%; P = 0.016). CONCLUSIONS Persistence, recurrence of pHPT, and reoperation rate are significantly lower after STP than LTSP in MEN1 patients. Genotype seems to be associated with the recurrence of pHPT. A mutation in exon 10 is an independent risk factor for recurrence after STP, and LTSP may not be recommended when exon 10 is mutated.

Impact of near-infrared fluorescence imaging plus indocyanine green fluorescence on postoperative hypoparathyroidism rates after total thyroidectomy and central neck lymph node dissection. Br J Surg 2024; 111:znae022. [PMID: 38381933 DOI: 10.1093/bjs/znae022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 11/16/2023] [Accepted: 01/06/2024] [Indexed: 02/23/2024]
Abstract
BACKGROUND Patients with thyroid carcinoma often undergo cervical lymph node dissection, which is associated with high rates of both transient and permanent postoperative hypoparathyroidism. The impact of near-infrared fluorescence imaging + indocyanine green (ICG) fluorescence on postoperative hypoparathyroidism rates after total thyroidectomy and central neck lymph node dissection was evaluated. METHODS All patients undergoing surgery between January 2019 and March 2023 were included and divided into three groups: a control group (parathyroid glands identified visually), a near-infrared fluorescence imaging alone group, and a near-infrared fluorescence imaging + ICG fluorescence group. The primary outcome was the transient and permanent postoperative hypoparathyroidism rates. Secondary outcomes were: length of surgery and number of parathyroid glands identified, inadvertently resected, and autotransplanted. RESULTS A total of 131 patients were included in the study (47 in the control group, 45 in the near-infrared fluorescence imaging alone group, and 39 in the near-infrared fluorescence imaging + ICG fluorescence group). The transient hypoparathyroidism rate was 48.9% in the control group, 37.8% in the near-infrared fluorescence imaging alone, and 5.1% in the near-infrared fluorescence imaging + ICG fluorescence group (P < 0.0001), while the permanent hypoparathyroidism rate was 8.5% in the control group, 2.2% in the near-infrared fluorescence imaging alone group, and 0% in the near-infrared fluorescence imaging + ICG fluorescence group (P = 0.096). The number of parathyroid glands identified was 159 of 188 in the control group, 165 of 180 in the near-infrared fluorescence imaging alone group, and 149 of 156 in the near-infrared fluorescence imaging + ICG fluorescence group (P = 0.002). Inadvertent resection of parathyroid glands occurred for 29 of 188 in the control group, 15 of 180 in the near-infrared fluorescence imaging alone group, and 7 of 156 in the near-infrared fluorescence imaging + ICG fluorescence group (P = 0.002), with subsequent parathyroid gland autotransplantation for 2 of 29 in the control group, 2 of 15 in the near-infrared fluorescence imaging alone group, and 3 of 7 in the near-infrared fluorescence imaging + ICG fluorescence group (P = 0.040). There was no difference in the median operating time between groups. CONCLUSION The use of near-infrared fluorescence imaging + ICG fluorescence decreased both transient and permanent hypoparathyroidism rates in patients undergoing total thyroidectomy and central neck lymph node dissection.

Abstract
INTRODUCTION Total thyroidectomy is associated with a high rate of transient or permanent hypoparathyroidism. During surgery, indocyanine green (ICG) fluorescein angiography can be used to detect and preserve well-vascularized parathyroid glands. This technique has been introduced as an intraoperative support to prevent postoperative hypoparathyroidism. MATERIAL AND METHODS One-hundred consecutive patients who had undergone total thyroidectomy were included in this study. Autofluoroscopy was used on the first dominant side of thyroidectomy and to identify the contralateral parathyroid glands. An intravenous bolus of 5 mg ICG (VERDYE, Diagnostic Green GmbH, Aschheim-Dornacht, Germany) was administered once. ICG fluorescein angiography was used as a "bridge" at the end of the first dominant hemithyroidectomy and after exposure of the parathyroid glands on the second side. This allowed us to (i) determine the vascularization of the first two parathyroid glands and (ii) define the blood vessels and thus the line of dissection of the parathyroid glands of the second resection side. Finally, autofluoroscopy was then applied outside the surgical area on the surgical specimen to assess forgotten parathyroid glands, which should therefore be re-implanted. Autofluoroscopy and ICG fluorescein angiography were evaluated in real time using the same technology, i.e., FLUOBEAM® LX (EUROPE - Fluoptics Grenoble, France; USA - Fluoptics Imaging Inc., Cambridge, MA, USA). The study was approved by the local ethics committee. RESULTS Autofluorescence and ICG fluorescein angiography were performed without any problems in all cases. A total of 370 parathyroid glands were detected in this series. ICG changed the surgical strategy for the first-side parathyroid glands in 5% of cases, i.e,. they were not well-vascularized and were re-implanted. The rate of transient hypoparathyroidism was 19%. The percentage of parathyroids in the surgical specimen was 3.5% and all were re-implanted during the same surgery. There was no case of postoperative definitive hypoparathyroidism when at least one parathyroid gland with a high fluorescence intensity was preserved on the first side of resection. CONCLUSION Use of ICG fluorescein angiography may contribute to predicting and thus preventing postoperative definitive hypoparathyroidism after total thyroidectomy. The results of this case series confirm recent studies. Caution is advised when weakly perfused parathyroid glands are discovered.

Abstract
OBJECTIVE Describe the diagnostic workup and postoperative results for patients treated by adrenalectomy for primary aldosteronism in France from 2010 to 2020. BACKGROUND Primary aldosteronism (PA) is the underlying cause of hypertension in 6% to 18% of patients. French and international guidelines recommend CT-scan and adrenal vein sampling as part of diagnostic workup to distinguish unilateral PA amenable to surgical treatment from bilateral PA that will require lifelong antialdosterone treatment.Adrenalectomy for unilateral primary aldosteronism has been associated with complete resolution of hypertension (no antihypertensive drugs and normal ambulatory blood pressure) in about one-third of patients and complete biological success in 94% of patients.These results are mainly based on retrospective studies with short follow-up and aggregated patients from various international high-volume centers. METHODS Here we report results from the French-Speaking Association of Endocrine Surgery (AFCE) using the Eurocrine® Database. RESULTS Over 11 years, 385 patients from 10 medical centers were eligible for analysis, accounting for >40% of adrenalectomies performed in France for primary aldosteronism over the period.Preoperative workup was consistent with guidelines for 40% of patients. Complete clinical success (CCS) at the last follow-up was achieved in 32% of patients, and complete biological success was not sufficiently assessed.For patients with 2 follow-up visits, clinical results were not persistent at 1 year for one-fifth of patients.Factors associated with CCS on multivariate analysis were body mass index, duration of hypertension, and number of antihypertensive drugs. CONCLUSIONS These results call for an improvement in thorough preoperative workup and long-term follow-up of patients (clinical and biological) to early manage hypertension and/or PA relapse.

Effect of the COVID-19 pandemic on surgery for indeterminate thyroid nodules (THYCOVID): a retrospective, international, multicentre, cross-sectional study. Lancet Diabetes Endocrinol 2023; 11:402-413. [PMID: 37127041 PMCID: PMC10147315 DOI: 10.1016/s2213-8587(23)00094-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Revised: 03/02/2023] [Accepted: 03/15/2023] [Indexed: 05/03/2023]
Abstract
BACKGROUND Since its outbreak in early 2020, the COVID-19 pandemic has diverted resources from non-urgent and elective procedures, leading to diagnosis and treatment delays, with an increased number of neoplasms at advanced stages worldwide. The aims of this study were to quantify the reduction in surgical activity for indeterminate thyroid nodules during the COVID-19 pandemic; and to evaluate whether delays in surgery led to an increased occurrence of aggressive tumours. METHODS In this retrospective, international, cross-sectional study, centres were invited to participate in June 22, 2022; each centre joining the study was asked to provide data from medical records on all surgical thyroidectomies consecutively performed from Jan 1, 2019, to Dec 31, 2021. Patients with indeterminate thyroid nodules were divided into three groups according to when they underwent surgery: from Jan 1, 2019, to Feb 29, 2020 (global prepandemic phase), from March 1, 2020, to May 31, 2021 (pandemic escalation phase), and from June 1 to Dec 31, 2021 (pandemic decrease phase). The main outcomes were, for each phase, the number of surgeries for indeterminate thyroid nodules, and in patients with a postoperative diagnosis of thyroid cancers, the occurrence of tumours larger than 10 mm, extrathyroidal extension, lymph node metastases, vascular invasion, distant metastases, and tumours at high risk of structural disease recurrence. Univariate analysis was used to compare the probability of aggressive thyroid features between the first and third study phases. The study was registered on ClinicalTrials.gov, NCT05178186. FINDINGS Data from 157 centres (n=49 countries) on 87 467 patients who underwent surgery for benign and malignant thyroid disease were collected, of whom 22 974 patients (18 052 [78·6%] female patients and 4922 [21·4%] male patients) received surgery for indeterminate thyroid nodules. We observed a significant reduction in surgery for indeterminate thyroid nodules during the pandemic escalation phase (median monthly surgeries per centre, 1·4 [IQR 0·6-3·4]) compared with the prepandemic phase (2·0 [0·9-3·7]; p<0·0001) and pandemic decrease phase (2·3 [1·0-5·0]; p<0·0001). Compared with the prepandemic phase, in the pandemic decrease phase we observed an increased occurrence of thyroid tumours larger than 10 mm (2554 [69·0%] of 3704 vs 1515 [71·5%] of 2119; OR 1·1 [95% CI 1·0-1·3]; p=0·042), lymph node metastases (343 [9·3%] vs 264 [12·5%]; OR 1·4 [1·2-1·7]; p=0·0001), and tumours at high risk of structural disease recurrence (203 [5·7%] of 3584 vs 155 [7·7%] of 2006; OR 1·4 [1·1-1·7]; p=0·0039). INTERPRETATION Our study suggests that the reduction in surgical activity for indeterminate thyroid nodules during the COVID-19 pandemic period could have led to an increased occurrence of aggressive thyroid tumours. However, other compelling hypotheses, including increased selection of patients with aggressive malignancies during this period, should be considered. We suggest that surgery for indeterminate thyroid nodules should no longer be postponed even in future instances of pandemic escalation. FUNDING None.

Abstract
Preoperative laryngoscopy is mandatory when there is a history of cervical or thoracic surgery, dysphonia, posteriorly developed thyroid carcinoma, or significant lymph node involvement in the central compartment. Postoperative laryngoscopy should be performed for any postoperative dysphonia, swallowing difficulties, respiratory symptoms, or loss of signal during neuromonitoring of the recurrent and/or vagus nerve. Neuromonitoring can be useful in thyroid surgery because it lowers the rate of transient recurrent palsy (RP), although no impact on permanent RP has been demonstrated. It facilitates location of the recurrent nerve. Continuous neuromonitoring of the vagus nerve can, in some situations, allow early detection of a signal drop during dissection near the recurrent nerve.

Abstract
Post-thyroidectomy cervical haematoma (PTCH) requiring reoperation occurs in fewer than 5% of patients but can be fatal or leave severe neurological sequelae if compressive. Risk factors besides anticoagulant treatments are discussed. Preoperative prevention complies with the recommendations of the French Society of Anaesthesia and Resuscitation (SFAR) for the management of antiaggregants and anticoagulants before and after the operation. Intraoperative prevention is centred on careful haemostasis, sometimes aided by coagulation tools and haemostatic agents, although there is no firm evidence of their effectiveness against the occurrence of PTCH. Systematic drainage of the thyroid cavity is no longer standard practice for the prevention of PTCH. Postoperatively, maintenance of normal blood pressure is essential to prevent PTCH, together with control of pain, coughing, nausea and vomiting. To reduce the risk of serious complications, medical and paramedical teams must be trained to recognise a haematoma and manage it so that it can be evacuated as a matter of extreme urgency, if necessary bedside, and then treated for its cause in the operating theatre.

Abstract
The SFE-AFCE-SFMN 2022 consensus deals with the management of thyroid nodules, a condition that is a frequent reason for consultation in endocrinology. In more than 90% of cases, patients are euthyroid, with benign non-progressive nodules that do not warrant specific treatment. The clinician's objective is to detect malignant thyroid nodules at risk of recurrence and death, toxic nodules responsible for hyperthyroidism or compressive nodules warranting treatment. The diagnosis and treatment of thyroid nodules requires close collaboration between endocrinologists, nuclear medicine physicians and surgeons, but also involves other specialists. Therefore, this consensus statement was established jointly by 3 societies: the French Society of Endocrinology (SFE), French Association of Endocrine Surgery (AFCE) and French Society of Nuclear Medicine (SFMN); the various working groups included experts from other specialties (pathologists, radiologists, pediatricians, biologists, etc.). This section deals with the initial work-up for thyroid nodules in adult patients, including clinical and biological evaluation, standardized ultrasound characterization and EU-TIRADS-based nodule selection for fine-needle aspiration biopsy. Indications for thyroid core-biopsies or open surgical biopsies and for cross-sectional imaging of the neck and upper chest are also mentioned.

Abstract
Despite the increasingly innovative techniques developed in thyroid surgery to offer patients minimally invasive and scarless interventions, conventional open procedures still account for most of the interventions performed in this field. The surgical incision length has been significantly reduced, from 6-9 cm to 3 cm, and therefore patients perceive the scar to be highly acceptable. In this technical note, we present the use of a new single retractor (APOLLO®; AFS MEDICAL GmbH, Teesdorf, Austria) for conventional open thyroidectomies with intraoperative neuromonitoring. This device offers several advantages: a) better exposure of the surgical field; b) less traction on skin flaps and neck muscles; and c) protection of the skin edges from the heat generated by energy-based devices/coagulating instruments, with consequent better healing.

Abstract
Introduction and importance Case presentation Conclusion Respiratory failure is an unprecedented manifestation of retrosternal goiter (RG). CT plays an important role in determining the likelihood of requiring an extra-cervical approach for RG. An ectopic goiter, previous neck surgery, extension below the level of the carina and/or into the posterior mediastinum favor an extra-cervical approach. A cautious attempt to remove RG through a cervicotomy should always be made, on account of reduced risk of surgical and aesthetic harm with this approach. If RG is performed by a skilled surgeon, familiar with its unique pitfalls, the assistance of a thoracic surgeon may seldom be required.

Abstract
PURPOSE Recent clinical practice guidelines consider thyroid lobectomy a viable alternative for low-risk papillary thyroid carcinoma PTC measuring 1-4 cm in size. We aimed to assess the likelihood of finding postoperatively determined high-risk histopathologic features that would lead to the recommendation of completion thyroidectomy. METHODS A retrospective review of patients who underwent total thyroidectomy for PTC measuring 1-4 cm in size between Jan 2012 and Jan 2018 was conducted. Patients with pre-operative high-risk characteristics were excluded: history of radiation exposure, positive family history, clinically suspicious cervical lymphadenopathy, and gross extrathyroidal extension (ETE). A hypothetical group of 245 patients remained eligible for lobectomy. The pathology specimens from the cancer-containing lobes were evaluated for high-risk features: aggressive histology, capsular and/or vascular invasion, microscopic ETE, and multifocality. A subgroup analysis was performed with 2 cm being the cut-off size. RESULTS The average age was 39 years with 73% being females. Mean cancer size was 16 mm. Evaluation of the cancer-containing lobe for high-risk features revealed: aggressive histology (33%), ETE (12%), capsular invasion (33%), vascular invasion (17%), and ipsilateral multifocality (30%). The cumulative risk of having ≥1 high-risk feature mandating completion thyroidectomy was 59%. The risk was considerably higher for lesions ≤2 cm compared to larger lesions (64% vs.48%; p = 0.049; RR = 1.3). CONCLUSIONS A considerable proportion of patients initially eligible for lobectomy have high-risk features that only become evident at pathology. Therefore, a comprehensive approach is advocated to determine the extent of surgery for PTC incorporating patient preferences regarding risks and benefits.

Abstract
Background: The recurrent laryngeal nerve (RLN) can be injured during thyroid surgery, which can negatively affect a patient's quality of life. The impact of intraoperative anatomic variations of the RLN on nerve injury remains unclear. Objectives of this study were to (1) better understand the detailed surgical anatomic variability of the RLN with a worldwide perspective; (2) establish potential correlates between intraoperative RLN anatomy and electrophysiologic responses; and (3) use the information to minimize complications and assure accurate and safe intraoperative neuromonitoring (IONM). Methods: A large international registry database study with prospectively collected data was conducted through the International Neural Monitoring Study Group (INMSG) evaluating 1000 RLNs at risk during thyroid surgery using a specially designed online data repository. Monitored thyroid surgeries following standardized IONM guidelines were included. Cases with bulky lymphadenopathy, IONM failure, and failed RLN visualization were excluded. Systematic evaluation of the surgical anatomy of the RLN was performed using the International RLN Anatomic Classification System. In cases of loss of signal (LOS), the mechanism of neural injury was identified, and functional evaluation of the vocal cord was performed. Results: A total of 1000 nerves at risk (NARs) were evaluated from 574 patients undergoing thyroid surgery at 17 centers from 12 countries and 5 continents. A higher than expected percentage of nerves followed an abnormal intraoperative trajectory (23%). LOS was identified in 3.5% of NARs, with 34% of LOS nerves following an abnormal intraoperative trajectory. LOS was more likely in cases of abnormal nerve trajectory, fixed splayed or entrapped nerves (including at the ligament of Berry), extensive neural dissection, cases of cancer invasion, or when lateral lymph node dissection was needed. Traction injury was found to be the most common form of RLN injury and to be less recoverable than previous reports. Conclusions: Multicenter international studies enrolling diverse patient populations can help reshape our understanding of surgical anatomy during thyroid surgery. There can be significant variability in the anatomic and intraoperative characteristics of the RLN, which can impact the risk of neural injury.

[PMID: 33707027 DOI: 10.1016/j.anplas.2020.12.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2020] [Revised: 12/07/2020] [Accepted: 12/09/2020] [Indexed: 10/22/2022]
Abstract
INTRODUCTION The anatomical subject is still a key element to learn complex procedures in plastic surgery. We present here the evaluation of an in-training operator on a SIMLIFE® model, hyper realistic model consisting in human bodies donated to science equipped with pulsating recirculation and reventilation device. MATERIAL AND METHODS From February 2019 to October 2019, 8 forearm flaps with radial proximal pedicle were harvested by the learner on a SIMLIFE® model. Conditions were as close as possible to the operating room : asepsy, sterile draping, assistant and instrumentation including electrocoagulation. RESULTS The procedure was decomposed in 13 distinct steps. Mean total surgery time was 90,5±11,62minutes. There was only one case of arterial pedicle lesion resulting in major blood leak. Bleeding was measured by fake blood loss from the SIMLIFE® console. Mean intraoperatoy bleeding was 171±108 milliliters. We review pros and cons of this new technology particulary suited for complex plastic and reconstructive surgery training. CONCLUSION Using SIMLIFE® technology we have a new mean to train for complex procedures in plastic and reconstructive surgery. This new technology could be applied to numerous other surgical procedures. Broader applications are still limited by cost and cadaver use legislation.

Metabolic Surgery and Class 1 Obesity (< 35 kg/m 2): a Prospective Study with Short-, Mid-, and Long-term Results Among Latinos. Obes Surg 2021; 31:2401-2409. [PMID: 33598844 DOI: 10.1007/s11695-021-05275-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2020] [Revised: 01/28/2021] [Accepted: 02/08/2021] [Indexed: 11/25/2022]
Abstract
INTRODUCTION Metabolic surgery for managing class 1 obesity and type 2 diabetes mellitus has recently gained popularity. The Latino population presents high rates of these diseases. Reports on surgical outcomes in this population are scarce. METHODS Prospective study with Mexican patients diagnosed with diabetes and class 1 obesity submitted to Roux-en-Y gastric bypass. The objective was to determine short-, mid-, and long-term outcomes (weight loss, metabolic, morbidity, and diabetes remission). Sub-analysis was included, based on preoperative usage of one (group A) or more (group B) oral hypoglycemic agents ± insulin. RESULTS Fifty-one patients with a mean body mass index of 33.1 ± 1.9 kg/m2, and glycated hemoglobin 7.2 ± 1.7% were included. Significant improvements were observed in almost every parameter. At 24, 36, and 60 months, complete diabetes remission was achieved in 73.8%, 52.2%, and 50% of patients with glycated hemoglobin levels of 5.7% ± 0.8%, 5.8% ± 0.5%, and 6.1% ± 0.8%, respectively. At 24, 36, and 60 months, patients in group A (N=28) showed 90.9%, 69.2%, and 75% remission, respectively, versus patients in group B (N=23), who had remission rates of 50%, 30%, and 25% during the same period. Diabetes relapse was higher in patients using ≥ 2 oral hypoglycemic agents ± insulin before surgery. CONCLUSION Gastric bypass is a safe and effective metabolic surgery that results in excellent mid- and long-term results among Mexicans. Patients using one drug preoperatively showed improved results and remission rates, which underscores the importance of intervening in the early stages of the disease.

Abstract
To evaluate the validity and reliability of an innovative training model for endocrine surgical procedures. A simulator training model for endocrine procedures (SimLife) was developed at an academic center. The model consisted of a realistic operating environment with a coherent simulated patient dynamized by pulsatile vascularization with simulated blood warmed to 37 °C, and ventilation. Training sessions were designed for adrenal and thyroid surgery, as well as neck dissection. The primary outcome of interest was to evaluate learners’ performance and satisfaction. Learners’ performance was evaluated based on a scoring scale that followed the Downing method for the assessment of competency. While learners’ satisfaction was evaluated using a Likert scale of 1 to 10 on four items (ease of learning, anatomic correspondence of landmarks, realism, and overall satisfaction). Participants were engaged in 32 training sessions. These included 24 adrenalectomies (conventional and laparoscopic both transabdominal and posterior), and 4 thyroid lobectomies with concomitant functional lateral compartment neck dissection. competency scores were procedure-specific addressing specific core components of a given procedure. Learners’ performance scored above average in all procedures evaluated. Satisfaction scores for the specified four items ranged between 8.43 (SD 0.87) and 8.89 (SD 0.96). No major events were reported for the adrenalectomies, while only one jugular vein injury occurred during neck dissection. SimLife is a hyper-realistic training model that allows for satisfactory acquisition of skills and the evaluation of performance progression. It has the potential to become a cornerstone in specialized surgical training.

Bariatric Surgical Simulation: Evaluation in a Pilot Study of SimLife, a New Dynamic Simulated Body Model. Obes Surg 2020; 30:4352-4358. [PMID: 32621055 PMCID: PMC7333933 DOI: 10.1007/s11695-020-04829-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Revised: 06/25/2020] [Accepted: 06/25/2020] [Indexed: 01/16/2023]
Abstract
Background The demand for bariatric surgery is high and so is the need for training future bariatric surgeons. Bariatric surgery, as a technically demanding surgery, imposes a learning curve that may initially induce higher morbidity. In order to limit the clinical impact of this learning curve, a simulation preclinical training can be offered. The aim of the work was to assess the realism of a new cadaveric model for simulated bariatric surgery (sleeve and Roux in Y gastric bypass). Aim A face validation study of SimLife, a new dynamic cadaveric model of simulated body for acquiring operative skills by simulation. The objectives of this study are first of all to measure the realism of this model, the satisfaction of learners, and finally the ability of this model to facilitate a learning process. Methods SimLife technology is based on a fresh body (frozen/thawed) given to science associated to a patented technical module, which can provide pulsatile vascularization with simulated blood heated to 37 °C and ventilation. Results Twenty-four residents and chief residents from 3 French University Digestive Surgery Departments were enrolled in this study. Based on their evaluation, the overall satisfaction of the cadaveric model was rated as 8.52, realism as 8.91, anatomic correspondence as 8.64, and the model’s ability to be learning tool as 8.78. Conclusion The use of the SimLife model allows proposing a very realistic surgical simulation model to realistically train and objectively evaluate the performance of young surgeons.

Abstract
The 2019 novel corona virus and the disease it causes (COVID-19) is a public health crisis that has profoundly modified the way medical and surgical care is delivered. Countries around the globe had a variable initial response to the COVID-19 pandemic from imposing massive lock downs and quarantine to surrendering to herd immunity. However, healthcare bodies worldwide recognized early on that a triumph against COVID-19 could only be achieved by maintaining the infrastructure of healthcare systems and their capacity to accommodate a potentially overwhelming increase in critical patient care needs. Therefore, they reacted by restricting medical care to emergency cases and postponing elective surgical procedures in all disciplines. The priority was made for treatment of COVID-19 patients and emergency cases. Nevertheless, the battle against the COVID-19 pandemic is still ongoing. In the absence of vaccines or effective drug treatments, its timeline remains uncertain and it cannot be forecast how long healthcare systems will need to cope with it in managing inpatient and outpatient services. Accordingly, extreme measures and restriction may become a recipe for a disaster in the context of the potential adverse health implications imposed by delaying timely medical and surgical care. Therefore, restrictive measures should be substituted with a comprehensive surgical and medical care strategy. One that provides a safe balance between the prevention of COVID-19 and the delivery of essential surgical care. This article provides an overview on how to safely deliver essential surgical care in the time of COIVD-19.

Abstract
BACKGROUND Bariatric surgery is considered a safe therapy to treat obesity. Postoperative complications are well known; however, there is a lack of data describing intraoperative complications and/or unexpected findings, and if there is further impact on outcomes. METHODS Retrospective study with patients operated between 2013 and 2016 at a single institution. All operative information was collected prospectively and aimed to analyze the incidence and causes of unexpected intraoperative findings, complications, change in surgical plan, extra surgeries, and procedure interruption in patients submitted to bariatric surgery. Secondarily, a morbidity analysis was performed, correlating intraoperative complications with postoperative complications and length of stay. RESULTS Four-hundred and five patients were included. Female sex comprised 82% of cases, and a median age of 38 years old was observed; almost 90% were gastric bypass. In 29.3% of cases, there were intraoperative findings, mainly adhesions, abdominal wall hernias, positive methylene blue test, hiatal hernias, and gastrointestinal stromal tumors. Associated surgeries were performed in 8.6% cases, and intraoperative adverse events reported in 7.1%, where organ injury and anastomosis problems were the most frequent. A change in the operative plan was done in 0.9% and surgery interruption in 1.2% of the cases. Early complications were observed in 6.6%. There was no correlation between intraoperative complications and length of stay or early complications. CONCLUSION Unexpected intraoperative findings/complications are common in bariatric surgery, but without increasing morbidity or length of stay. Surgery suspension, change in the planned technique, or adding extra (non-bariatric) procedures may occur.

Abstract
INTRODUCTION In 2015, we reported our experience with the learning curve in genital reassignment surgery and highlighted a four-step learning concept. CLINICAL CASE In this article, we present our first vaginoplasty performed on a humanoid model SIMLIFE®, a human body associated with a pulsating circulation device and a ventilation device. RESULTS The surgical technique included 14 steps. The total surgical time was 182minutes. There was no intraoperative complication, and there was no damage to the urethra or rectum. The intraoperative bleeding measured by the loss of operative fluid was 280mL. We discuss the advantages of this technology perfectly adapted to transsexual surgery. CONCLUSION We demonstrated the feasibility of vaginoplasty performed on a humanoid model SIMLIFE® and highlighted improvement of the surgical skills with this model. This technology could find many other surgical applications. However, it faces cost constraints and legislation on corpses.

Abstract
BACKGROUND Published data in the last decade showed that a majority of adrenal operations are done by surgeons performing only one such case per year and based on the distribution of personal workloads 'high-volume' surgeons are defined as those doing 4 or more cases/year. PURPOSE This paper summarises literature data identified by a working group established by the European Society of Endocrine Surgeons (ESES). The findings were discussed during ESES-2019 conference and members agreed on a consensus statement. RESULTS The annual of adrenal operations performed yearly in individual countries was reported to be 800/year in UK and over 1600/year in France. The learning curve of an individual surgeon undertaking laparoscopic, retroperitoneoscopic or robotic adrenalectomy is estimated to be 20-40 cases. Preoperative morbidity and length of stay are more favourable in high-volume centres. CONCLUSION The main recommendations are that adrenal surgery should continue only in centres performing at least 6 cases per year, surgery for adrenocortical cancer should be restricted to centres performing at least 12 adrenal operations per year, and an integrated multidisciplinary team should be established in all such centres. Clinical information regarding adrenalectomies should be recorded prospectively and contribution to the established EUROCRINE and ENSAT databases is strongly encouraged. Surgeons wishing to develop expertise in this field should seek mentorship and further training from established adrenal surgeons.

Abstract
BACKGROUND Hypocalcemia is the most common complication following total thyroidectomy. Few factors may relate with increased risk of postoperative hypocalcemia. Preoperative vitamin D values have been evaluated in few studies, but reports present conflicting data. Aim of our study is to evaluate the association of preoperative vitamin D values and hypocalcemia following total thyroidectomy. METHODS A retrospective analysis of patients undergoing total thyroidectomy in our department of endocrine surgery between November 2012 and November 2015 was performed. RESULTS Mean age of patients was 56.2 years (±14.0) and sex ratio (F:M) was 4.3:1. Sixty-four patients (17.4%) had preoperative vitamin D insufficiency (x<25 nmol/L), 138 patients (37.5%) vitamin D deficiency (25<x<50 nmol/L) and 166 patients (45.1%) vitamin D sufficiency (x>50 nmol/L). Following total thyroidectomy for both benign and malignant pathology, 66 patients (17.9%) had symptomatic hypocalcemia (x<2.0 mmol/L) requiring medical treatment (group 1), 64 patients (17.4%) biochemical hypocalcemia (2<x<2.1 mmol/L) not requiring treatment (group 2) and 238 patients (64.7%) had normal levels (x>2.1 mmol/L, group 3). Mean postoperative PTH value was 25.4 pg/ml (range 2-61). No statistical correlation between postoperative serum calcium and preoperative vitamin D values (R=-0.001, P=0.9849) was found nor associations were found regarding age, sex, type of thyroid disease or BMI. CONCLUSIONS In our cohort of patients, preoperative vitamin D levels were not associated with a higher risk of hypocalcemia following total thyroidectomy. Postoperative PTH appears to be the most sensible item to predict the risk of postoperative symptomatic hypocalcemia.

Abstract
INTRODUCTION Delayed graft function (DGF) has a significant impact on kidney transplantation outcome. One of the underlying pivotal mechanisms is organ preservation and associated hypothermia and biochemical alteration. AREAS COVERED This paper focuses on organ preservation and its clinical consequences and describes 1. A comprehensive presentation of the pathophysiological mechanism involved in delayed graft function development; 2. The impact on endothelial cells and microvasculature integrity and the consequences on transplanted organ outcome; 3. The reassessment of dynamic organ preservation motivated by the growing use of extended criteria donors and the interest in the potential of normothermia; 4. The role of oxygenation during dynamic preservation; and 5. Novel oxygen carriers and their proof of concept in transplantation, among which M101 (HEMO2life®) is currently the most extensively investigated. EXPERT OPINION Metabolic disturbances and imbalance of oxygen supply during preservation highlight the importance of providing oxygen. Normothermia, permitted by recent advances in machine perfusion technology, appears to be the leading edge of preservation technology. Several oxygen transporters are compatible with normothermia; however, only M101 also demonstrates compatibility with standard hypothermic preservation.

Abstract
Marginal kidney graft preservation in machine perfusion (MP) is well-established. However, this method requires improvement in order to mitigate oxidative stress during ischemia-reperfusion, by using oxygenation or an O2 carrier with anti-oxidant capacities (hemoglobin of the marine worm; M101). In our preclinical porcine (pig related) model, kidneys were submitted to 1h-warm ischemia, followed by 23 h hypothermic preservation in Waves® MP before auto-transplantation. Four groups were studied: W (MP without 100%-O2), W-O2 (MP with 100%-O2; also called hyperoxia), W-M101 (MP without 100%-O2 + M101 2 g/L), W-O2 + M101 (MP with 100%-O2 + M101 2 g/L) (n = 6/group). Results: Kidneys preserved in the W-M101 group showed lower resistance, compared to our W group. During the first week post-transplantation, W-O2 and W-M101 groups showed a lower blood creatinine and better glomerular filtration rate. KIM-1 and IL-18 blood levels were lower in the W-M101 group, while blood levels of AST and NGAL were lower in groups with 100% O2. Three months after transplantation, fractional excretion of sodium and the proteinuria/creatinuria ratio remained higher in the W group, creatininemia was lower in the W-M101 group, and kidney fibrosis was lower in M101 groups. We concluded that supplementation with M101 associated with or without 100% O2 improved the Waves® MP effect upon kidney recovery and late graft outcome.

Abstract
BACKGROUND Few long-term studies define the appropriate extent of surgery and recurrence rates for unilateral multinodular goiter. We compared the rate and time to reoperation in patients with multinodular goiter who underwent lobectomy to that of patients with benign solitary nodule. METHODS Retrospective study of a prospective database of all patients who underwent lobectomy for multinodular goiter or solitary nodule from 1991 to 2017. We analyzed reoperation rates and time to reoperation. Reoperation was defined as the need for completion thyroidectomy determined the following citeria: nodule greater than 3 cm, multiple nodules, nodule growth or suspicion for malignancy by ultrasound or fine-needle aspiration biopsy, or compressive symptoms. RESULTS Included in the study were 2,675 lobectomies; 852 (31.85%) for multinodular goiter. In total, 394 patients (14.7%) underwent reoperation: 261 (30.6%) with a previous multinodular goiter and 133 (7.29%) with solitary nodule (P < .0001). A total of 80% of the patients with multinodular goiter and 67.66% with solitary nodule recurred as multinodular goiter; 3.5% of all recurrences were carcinomas. The mean time to reoperation was 14.8 years, without difference between groups (P = .5765). Patients without reoperation were younger (47 ± 15 vs 54 ± 13 years of age, P < .0001) and more likely to be male (P < .0001). CONCLUSION Lobectomy for unilateral multinodular goiter is the procedure of choice given the length of time to reoperation. Patients and surgeons should be aware of the need for long-term surveillance.

Abstract
BACKGROUND Pheochromocytoma (PHEO) in pregnancy is a life-threatening condition. Its management is challenging with regards to the timing and type of surgery. METHODS A retrospective review of the management of ten patients diagnosed with pheochromocytoma during pregnancy was performed. Data were collected on the initial diagnostic workup, symptoms, treatment, and follow-up. RESULTS PHEO was diagnosed in ten patients who were between the 10th and the 29th weeks of pregnancy. Six patients had none to mild symptoms, while four had complications of paroxysmal hypertension. Imaging investigations consisted of MRI, CT scan and ultrasounds. All had urinary metanephrines, measured as part of their workup. Three patients had MEN 2A, one VHL syndrome, one suspected SDH mutation. All patients were treated either with α/β blockers or calcium channel blockers to stabilize their clinical conditions. Seven patients underwent a laparoscopic adrenalectomy before delivery. Three out of these seven patients had a bilateral PHEO and underwent a unilateral adrenalectomy of the larger tumor during pregnancy, followed by a planned cesarean section and a subsequent contralateral adrenalectomy within a few months after delivery. Three patients had emergency surgery for maternal or fetal complications, with C-section followed by concomitant or delayed adrenalectomy. All newborns from the group of planned surgery were healthy, while two out three newborns within the emergency surgery group died shortly after delivery secondary to cardiac and pulmonary complications. CONCLUSIONS PHEO in pregnancy is a rare condition. Maternal and fetal prognosis improved over the last decades, but still lethal consequences may be present if misdiagnosed or mistreated. A thorough multidisciplinary team approach should be tailored on an individual basis to better manage the pathology. Unilateral adrenalectomy in a pregnant patient with bilateral PHEO may be an option to avoid the risk of adrenal insufficiency after bilateral adrenalectomy.

Abstract
BACKGROUND Obesity has an impact on health-related quality of life (HRQoL) and bariatric surgery may improve HRQoL in addition to severe obesity-related comorbidities. Aim of the study was to evaluate HRQoL following sleeve gastrectomy and the sensitivity of two HRQoL questionnaires: the Impact of Weight on Quality Of Life-Lite (IWQOL-Lite) and the World Health Organization-Quality Of Life-Bref (WHOQOL-Bref) scales. METHODS Data were prospectively collected from 149 adult patients submitted to laparoscopic sleeve gastrectomy, before, at 6 and 12 months post-operatively. HRQoL was measured using both the WHOQOL-Bref and the IWQOL-Lite questionnaires. RESULTS Mean age was 40.5±11.9 years, mean initial weight 118.7±30.3 kg and mean preoperative Body Mass Index (BMI) was 44.1±6.3 kg/m². Excess weight loss (EWL) was 53.1% and 68.8% respectively at 6 and 12 months postoperatively. Both questionnaires showed significant improvement of HRQoL 12 months after the procedure. Two over 4 domains (physical and psychological health) of the WHOQOL-Bref improved at 6 months whereas all of the 5 domains of the IWQOL-Lite did. The IWQOL-Lite questionnaire pointed out a significant enhancement both at 6 and 12 months. CONCLUSIONS HRQoL is improved after sleeve gastrectomy. The specific obesity questionnaire IWQOL-Lite seems to be more sensitive than the generic WHOQOL-Bref to detect amelioration of HRQoL.

Thyroid Hürthle cell tumors: research of potential markers of malignancy. J Endocrinol Invest 2016; 39:153-8. [PMID: 26188382 DOI: 10.1007/s40618-015-0356-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2015] [Accepted: 07/06/2015] [Indexed: 10/23/2022]
Abstract
INTRODUCTION Hurthle cell tumors (HCTs) are rare thyroid neoplasia. To date, capsular and/or vascular invasion are the only findings predicting malignancy. Recently, mutation of 19p13, encoding two proteins involved in cell proliferation and apoptosis (GRIM-19 and p19), has been described. The aim of our study is to evaluate the cellular proliferation index (Ki67), GRIM-19 and p19 expression as diagnostic markers of malignancy in HCT. MATERIALS AND METHODS Eighty patients with HCT (32 carcinomas, 48 adenomas) whom underwent surgery in our center were included. Samples of both neoplastic lesions and adjacent normal thyroid tissue were analyzed by means of tissue micro-arrays. Correlations between expressions of Ki67, GRIM-19 and p19 and final histology were analyzed. RESULTS Mean size of the lesion was higher in carcinomas than in adenomas (p = 0.01). GRIM-19 and p19 were significantly underexpressed in Hurthle cells tumors compared to normal tissue (p = 0.0004 and p = 0.0001, respectively). Ki67 and GRIM-19 were, respectively, higher and down-expressed in carcinomas compared to adenomas (p = 0.0004 and p = 0.005, respectively). On multivariate analysis, size correlates with carcinoma diagnosis. Neither GRIM-19 nor Ki67 index was related to size. The expression of p19 was reduced in both adenoma and carcinoma but differences were not statistically significant (p = 0.13). CONCLUSIONS Our study suggest that Ki67 and GRIM-19 correlate with malignancy in HCT. The expression of p19 is down-regulated in HCT, but it is not diagnostic of carcinoma. Ki67 and GRIM-19 may potentially help as cytological markers of malignancy in HCT.

Abstract
OBJECTIVES/HYPOTHESIS Intraoperative neuromonitoring identifies recurrent laryngeal nerve (RLN) injury and gives prognostic information regarding postoperative glottic function. Loss of the neuromonitoring signal (LOS) signifies segmental type 1 or global type 2 RLN injury. This study aimed at identifying risk factors for RLN injury and determining vocal fold (VF) function initially and 6 months after definitive LOS. STUDY DESIGN Prospective study encompassing 21 hospitals from 13 countries. METHODS Included in this study were patients with persistent intraoperative LOS. RESULTS At first postoperative laryngoscopy, early VF palsy was present in 94 of all 115 patients with LOS (81.7%): in 53 of 56 patients (94.6%) with type 1 injury and 41 of 59 patients (69.5%) with type 2 injury. In LOS type 1, women outnumbered men >5-fold. Traction produced LOS type 1 in 38 of 56 patients (67.9%) and LOS type 2 in 54 of 59 patients (91.5%). Course of the RLN posterior and/or anterior to the inferior thyroid artery, extralaryngeal branching, or tuberculum of Zuckerkandl did not increase VF palsy rates. Permanent VF palsy rates were also lower (P = .661) after LOS type 2 than after LOS type 1: 6.8% (four of 59 patients) versus 10.7% (six of 56 patients). Intraoperative administration of steroids did not diminish postoperative VF palsy rates. CONCLUSIONS LOS type 1 entails more severe nerve damage than LOS type 2, affecting women disproportionately. Both LOS types, being primarily associated with traction injury, are unaffected by variant neck anatomy in expert hands and unresponsive to steroids. LEVEL OF EVIDENCE 2b Laryngoscope, 126:1260-1266, 2016.

Abstract
BACKGROUND Nonfunctioning pancreatic neuroendocrine tumors (NF-PNETs) are often discovered at a small size. No clear consensus exists on the management of NF-PNETs ≤ 2 cm. The aim of our study was to determine the prognostic value of indicators of malignancy in sporadic NF-PNETs ≤ 2 cm. METHODS Eighty patients were evaluated retrospectively in 7 French University Hospital Centers. Patients were managed by operative resection (operative group [OG]) or observational follow-up (non-OG [NOG]). Pathologic characteristics and outcomes were analyzed. RESULTS Sixty-six patients (58% women) were in the OG (mean age, 59 years; 95% CI, 56.0-62.3; mean tumor size, 1.6 cm; 95% CI, 1.5-1.7); 14 (72% women, n = 10) were in the NOG (mean age, 63 years; 95% CI, 56-70; mean tumor size, 1.4 cm; 95% CI, 1.0-1.7). All PNETs were ranked using the European Neuroendocrine Tumor Society grading system. Fifteen patients (19%) had malignant tumors defined by node or liver metastasis (synchronous or metachronous). The median disease-free survival was different between malignant and nonmalignant PNETs, respectively: 16 (range, 4-72) versus 30 months (range, 1-156; P = .03). On a receiver operating characteristic (ROC) curve, tumor size had a significant impact on malignancy (area under the curve [AUC], 0.75; P = .03), but not Ki-67 (AUC, 0.59; P = .31). A tumor size cutoff was found on the ROC curve at 1.7 cm (odd ratio, 10.8; 95% CI; 2.2-53.2; P = .003) with a sensitivity of 92% and a specificity of 75% to predict malignancy. CONCLUSION Based on our retrospective study, the cutoff of 2 cm of malignancy used for small NF-PNETs could be decreased to 1.7 cm to select patients more accurately.

Abstract
BACKGROUND Laparoscopic adrenalectomy (LA) is the standard treatment for benign adrenal lesions. The laparoscopic approach has also been increasingly accepted for adrenal metastases but remains controversial for adrenocortical carcinoma (ACC). In a retrospective cohort study we compared the outcome of LA versus open adrenalectomy (OA) in the treatment of stage I and II ACC. METHODS This was a double cohort study comparing the outcome of patients with stage I/II ACC and a tumor size <10 cm submitted to LA or OA at Lille University Hospital referral center from 1985 to 2011. Main outcomes analyzed were: postoperative morbidity, overall survival, and disease-free survival. RESULTS Among 111 consecutive patients operated on for ACC, 34 met the inclusion criteria. LA and OA were performed in 13 and 21 patients, respectively. Baseline patient characteristics (gender, age, tumor size, hormonal secretion) were similar between groups. There was no difference in postoperative morbidity, but patients in LA group were discharged earlier (p < 0.02). After a similar follow-up (66 ± 52 for LA and 51 ± 43 months for OA), Kaplan-Meier estimates of disease-specific survival and disease-free survival were identical in both groups (p = 0.65, p = 0.96, respectively). CONCLUSIONS LA was associated with a shorter length of stay and did not compromise the long-term oncological outcome of patients operated on for stage I/II ACC ≤ 10 cm ACC. Our results suggest that LA can be safely proposed to patients with potentially malignant adrenal lesions smaller than 10 cm and without evidence of extra-adrenal extension.

Abstract
BACKGROUND Fine needle aspiration (FNA) is a widely used practice to assess thyroid lesions, with a low morbidity rate. Although neck hematomas following this procedure are quite common, only three cases of massive hemorrhage causing acute airways obstruction have been previously described. CASE REPORT We report the case of a 74 years old female with acute respiratory distress following ultrasound-guided FNA for a right paraisthmic thyroid nodule. The patient was admitted to the Emergency Room (ER) 6 hours after the procedure with a large neck hematoma compressing the cervical trachea and requiring surgical decompression. Patient underwent endotracheal intubation followed by isthmectomy and evacuation of the hematoma. Extubation was made 24 hours later in the Intensive Care Unit and the patient was discharged after 48 hours uneventfully. CONCLUSIONS Acute thyroid hemorrhage following FNA is very rare but still possible. Prompt intervention is mandatory for patients with rapidly evolving symptoms.
