The impact of intraoperative “Nerve Monitoring” in a tertiary referral center for thyroid and parathyroid surgery

The most fearsome complication in thyroid surgery is the temporary or definitive recurrent laryngeal nerve (RLN) injury. The aim of our study was to evaluate the impact of intraoperative neuromonitoring (IONM) on postoperative outcomes after thyroid and parathyroid surgery. From October 2014 to February 2016, a total of 80 consecutive patients, with high risk of RLN injuries, underwent thyroid and parathyroid surgery. They were divided in two groups (IONM group and control group), depending on whether neuromonitoring was used or not. We used the Nerve Integrity Monitoring System (NIM)-Response 3.0 (R) (Medtronic Xomed (R)). The operation time (p=0.014). and the length of hospital stay (LOS) (p=0.14) were shorter in the IONM group. Overall mean follow-up was 96.7 +/- 14.3 months. The rate of transient RLN palsy was 2.6% in IONM group and 2.5% in the control group (p=not significant). Only one case of definitive RLN injury was reported in control group. No differences were reported between the two groups in terms of temporary or definitive RLN injury. Routine use of IOMN increases the surgery cost, but overall, it leads to long-term cost savings thanks to the reduction of both operating times (106.3 +/- 38.7 vs 128.1 +/- 39.3, p: 0.01) and LOS (3.2 +/- 1.5 vs 3.7 +/- 1.5 days, p=0.14). Anatomical visualization of RLN remains the gold standard in thyroid and parathyroid surgery. Nevertheless, IONM is proved to be a valid help without the ambition to replace surgeon's experience

Video-assisted thyroidectomy

BACKGROUND: In 1998, we developed a technique for video-assisted thyroidectomy (VAT). In this article we report on the entire series of patients who underwent VAT and discuss the results obtained. STUDY DESIGN: Forty-seven patients were selected for VAT. Eligibility criteria were: thyroid nodules of 35 mm or less in maximum diameter; estimated thyroid volume within normal range or slightly enlarged; small, low-risk papillary carcinomas; neither previous neck surgery nor irradiation; and no thyroiditis. After a learning period, VAT was proposed also for completion thyroidectomy (of previous video-assisted lobectomy) and nodules with maximum diameter up to 45 mm. The procedure is performed by a totally gasless video-assisted technique through a single 1.5- to 2.0-cm skin incision. Dissection is performed under endoscopic vision using a technique very similar to conventional operation. RESULTS: Fifty-three VATs were attempted on 47 patients. Thirty-three lobectomies, 10 total thyroidectomies, and 6 completion thyroidectomies were successfully performed. Six patients with papillary carcinoma underwent central neck lymph node removal by the same access. Mean operative time was 86.8 minutes for lobectomy, 116.0 minutes for total thyroidectomy, and 77.5 minutes for completion thyroidectomy. Conversion rate was 7.5%. Postoperative complications included one transient recurrent nerve palsy, three transient symptomatic postoperative hypocalcemias, and one wound infection. The cosmetic result was considered excellent by most of the patients who successfully underwent VAT. CONCLUSIONS: VAT is feasible and safe and allows for an excellent cosmetic result. Not all patients are eligible for this procedure, but in selected cases it can be a valid option for the surgical treatment of thyroid diseases

Domiciliary Non-invasive Ventilation in COPD:An International Survey of Indications and Practices

Despite the fact that metanalyses and clinical guidelines do not recommend the routine use of domiciliary non-invasive ventilation (NIV) for patients diagnosed with severe stable Chronic Obstructive Pulmonary Disease (COPD) and with chronic respiratory failure, it is common practice in some countries.We conducted an international web-survey of physicians involved in provision of long-term NIV to examine patterns of domiciliary NIV use in patients diagnosed with COPD.The response rate was 41.6%. A reduction of hospital admissions, improvements in quality of life and dyspnea relief were considered as the main expected benefits for patients. Nocturnal oxygen saturation assessment was the principal procedure performed before NIV prescription. Recurrent exacerbations (>3) requiring NIV and failed weaning from in hospital NIV were the most important reasons for starting domiciliary NIV. Pressure support ventilation (PSV) was the most common mode, with low intensity settings (PSV-low) the most popular (44.4 30.1%) compared with high intensity (PSV-high) strategies (26.9 +/- 25.9%), with different geographical preferences.COPD is confirmed to be a common indication for domiciliary NIV. Recurrent exacerbations and failed weaning from in-hospital NIV were the main reasons for its prescription

Continuous vs intermittent Non-Invasive blood pressure MONitoring in preventing postoperative organ failure (niMON): study protocol for an open-label, multicenter randomized trial

Abstract Background Blood pressure has become one of the most important vital signs to monitor in the perioperative setting. Recently, the Italian Society of Anesthesia Analgesia Resuscitation and Intensive Care (SIAARTI) recommended, with low level of evidence, continuous monitoring of blood pressure during the intraoperative period. Continuous monitoring allows for early detection of hypotension, which may potentially lead to a timely treatment. Whether the ability to detect more hypotension events by continuous noninvasive blood pressure (C-NiBP) monitoring can improve patient outcomes is still unclear. Here, we report the rationale, study design, and statistical analysis plan of the niMON trial, which aims to evaluate the effect of intraoperative C-NiBP compared with intermittent (I-NiBP) monitoring on postoperative myocardial and renal injury. Methods The niMon trial is an investigator-initiated, multicenter, international, open-label, parallel-group, randomized clinical trial. Eligible patients will be randomized in a 1:1 ratio to receive C-NiBP or I-NiBP as an intraoperative monitoring strategy. The proportion of patients who develop myocardial injury in the first postoperative week is the primary outcome; the secondary outcomes are the proportions of patients who develop postoperative AKI, in-hospital mortality rate, and 30 and 90 postoperative days events. A sample size of 1265 patients will provide a power of 80% to detect a 4% absolute reduction in the rate of the primary outcome. Conclusions The niMON data will provide evidence to guide the choice of the most appropriate intraoperative blood pressure monitoring strategy.

MINIMALLY INVASIVE VIDEO-ASSISTED FUNCTIONAL LATERAL NECK DISSECTION FOR METASTATIC PAPILLARY THYROID CARCINOMA

Functional lateral neck dissection requires a large incision providing adequate exposure of the surgical field. We evaluated the feasibility of minimally invasive video-assisted functional lateral neck dissection (VALNED) in patients with papillary thyroid carcinoma (PTC). Low-risk PTC patients with lateral neck metastases <2 cm, in absence of any evidence of great vessels involvement, were considered eligible. After accomplishing total thyroidectomy and central neck clearance, dissection was performed under endoscopic vision by using a technique very similar to conventional surgery through the single 4-cm skin incision used for thyroidectomy. Two patients were selected: 1 underwent bilateral and 1 unilateral VALNED. The mean number of the removed nodes was 25 per side. Both patients experienced transient postoperative hypocalcemia. No other complication occurred. No evidence of residual or recurrent disease was found at follow-up. VALNED is feasible, and the results are encouraging. For definitive conclusions, larger series and comparative studies are necessar

Video-assisted thyroidectomy: report of a 7-year experience in Rome

BACKGROUND AND AIMS: We report on our series of patients selected for video-assisted thyroidectomy (VAT) over a 7-year period. MATERIALS AND METHODS: VAT is a gasless procedure performed under endoscopic vision through a single 1.5-2.0 cm skin incision. The eligibility criteria are thyroid nodules < or =35 mm, thyroid volume <30 ml, and no previous conventional neck surgery. Small, low-risk papillary thyroid carcinomas (PTC) were considered eligible. RESULTS: There were 521 VATs attempted. Conversion was necessary six times (difficult dissection in one case, large nodule size in three, and gross lymph node metastases in two). Thyroid lobectomy was successfully accomplished in 113 cases, total thyroidectomy in 398, and completion thyroidectomy in 14. In 66 patients, the central neck nodes were removed through the same access. Pathology showed benign diseases in 313 cases, PTC in 187, and medullary microcarcinoma in 1. Postoperative complications included 9 transient recurrent nerve palsies, 73 transient hypocalcemias, 3 definitive hypoparathyroidisms, 1 postoperative haematoma, and 2 wound infections. The cosmetic result was excellent. In patients with PTC, no evidence of recurrent disease was shown. CONCLUSIONS: The indications for VAT are still limited. Nonetheless, in selected patients, it seems a valid option for thyroidectomy and even preferable to conventional surgery because of its significant advantages, especially in terms of cosmetic result

Video-Assisted Thyroidectomy for Papillary Thyroid Carcinoma: Oncologic Outcome in Patients with Follow-Up\ua0 65\ua010 Years

Background: Video-assisted thyroidectomy (VAT) arisen as a valid treatment for selected patients with papillary thyroid carcinoma (PTC), but no data concerning long-term oncologic outcome are available. The primary aim of the study was to evaluate the oncologic outcome of patients who underwent VAT for PTC with a follow-up\ua0 65\ua010\ua0years. Methods: The medical charts of all the patients who successfully underwent VAT for PTC were reviewed. The patients with a minimum follow-up period of 120-months were included. Patients with unifocal PTC\ua0 64\ua01\ua0cm, in the absence of lymph node metastases, without gross extracapsular invasion and age\ua0<\ua045\ua0years were considered \u201clow-risk\u201d patients and followed with ultrasound and serum thyroglobulin (sTg) on levothyroxine (LT4); the remaining patients underwent nuclear medicine evaluation. Results: Two hundred and fifty-seven patients, operated on between May 2000 and October 2006, were included. Postoperative complications included four transient recurrent palsies, 76 transient and 1 permanent hypocalcemia. One hundred and four low-risk patients were followed with ultrasound and sTg on LT4. At a mean follow-up of 136.6\ua0months, mean sTg on LT4 was 0.1\ua0\ub1\ua00.1\ua0ng/ml. None of them showed recurrence. The remaining 153 patients underwent nuclear medicine evaluation. Among these 153, 62 did not undergo radioiodine ablation (RAI). At a mean follow-up of 150.8\ua0months, mean sTg on LT4 was 0.1\ua0\ub1\ua00.1\ua0ng/ml. None of them showed recurrence. The remaining 91 patients underwent RAI. Mean pre-RAI sTg off-LT4 was 8.3\ua0\ub1\ua05.8\ua0ng/ml, mean radioiodine uptake was 2.8\ua0\ub1\ua04.4%. Among these 91, three pN1a patients developed a lateral neck node recurrence. No other recurrence was registered. At the latest follow-up mean sTg on LT4 in this subgroup of patients was 0.1\ua0\ub1\ua00.2\ua0ng/ml. Conclusions: The long-term ( 65\ua010\ua0years) oncologic outcome further demonstrates that VAT is a valid option for selected PTC patients

Retroperitoneoscopic adrenalectomy: tips and tricks

Posterior retroperitoneoscopic adrenalectomy has recently increased in popularity and currently adopted in about 20% of referral centers. It may provide more direct access to the adrenals, thus avoiding post-operative adhesions and the need for patient repositioning in bilateral adrenalectomy. Although it has been suggested to be feasible for large tumors, large tumor size is indicated as the main limitation of PRA, mainly because of the small space available for dissection

Central neck lymph node removal during minimally invasive video-assisted thyroidectomy for thyroid carcinoma: a feasible and safe procedure

BACKGROUND AND PURPOSE: In 1998, we developed a technique for video-assisted thyroidectomy (VAT) which we proposed using also in patients with small low-risk papillary thyroid carcinomas (PTC). In some cases, enlarged lymph nodes are incidentally found at surgery for PTC. These nodes should be removed because of the risk of metastases. In this paper, we report on the patients in whom we removed enlarged central neck lymph nodes during VAT for PTC and discuss the feasibility and safety of video-assisted central neck lymph node dissection (VALD). PATIENTS AND METHODS: The procedure is performed by a totally gasless video-assisted technique through a single 1.5-to 2.0-cm skin incision above the sternal notch. Dissection is performed under endoscopic vision using a technique very similar to that of conventional surgery. Only enlarged lymph nodes were removed and sent for frozen section examination (FS). No other dissection was performed in case of negative FS. Five patients underwent VALD during VAT for PTC. RESULTS: The mean number of lymph nodes removed was 2.4. No metastases were found at FS or final histology examination. Postoperative complications included two transient postoperative hypocalcemias. No evidence of residual or recurrent disease was observed at postoperative follow-up. The cosmetic result was excellent. CONCLUSION: Our experience demonstrates that removal of central compartment lymph nodes is feasible and safe. Perhaps also complete central neck lymph node dissection can be performed. Some doubts persist about the oncologic validity of this approach. For definitive conclusions, larger series and comparative studies are necessary
