RESUMO
BACKGROUND: Nowadays, minimally invasive video-assisted thyroidectomy (MIVAT) is considered a safe and effective option. However, its complication rate has not been specifically discussed yet. The aim of this systematic review was enrolling a large number of studies to estimate early and late complications (transient and definitive, uni- and bilateral laryngeal nerve palsy; transient and definitive hypocalcemia; cervical hematoma; hypertrophic or keloid scar) of MIVAT compared with conventional technique. METHODS: The review was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria in PubMed and Embase. Search terms were "minimally invasive," "video-assisted," and "thyroidectomy." We enrolled randomized clinical trials, nonrandomized trials, and noncontrolled trials. RESULTS: Thirty-two articles were considered suitable. Complication rate of MIVAT was quite similar to conventional technique: only one randomized trial found a significant difference concerning overall skin complication, and a single trial highlighted hypocalcemia significantly increased in MIVAT, concerning serologic value only. No difference concerning symptomatic nor definitive hypocalcemia was found. CONCLUSIONS: We can confirm that MIVAT is a safe technique. It should be adopted in mean-high-volume surgery centers for thyroidectomy, if a strict compliance with indication was applied.

BACKGROUND: The lungs are among the first organ affected by remote metastases from many primary tumors. The surgical resection of isolated pulmonary metastases represents an important and effective element of therapy. This is a retrospective study about our entire experience with pulmonary resection for metastatic cancer using 1318-nm neodymium-doped yttrium-aluminum garnet laser. METHOD: In this single-institution study, we retrospectively analyzed a group of 209 patients previously treated for primary malignant solid tumors. We excluded 103 patients. The number and location of lesions in the lungs was determined using chest computed tomography and positron emission tomography-computed tomography. Disseminated malignancy was excluded. All pulmonary laser resections are performed via an anteroaxillary muscle-sparing thoracotomy. All lesions were routinely removed by laser with a small (5-10 mm) margin of the healthy lung. Patients received systematic lymph node sampling with intraoperative smear cytology of sampled lymph nodes. RESULTS: Mortality at 2 years from the first surgery is around 20% (10% annually). This value increases to 45% in the third year. The estimated median survival for patients who underwent the first surgery is reported to be approximately 42 months. CONCLUSION: Our results show that laser resection of lung metastases can achieve good result, in terms of radical resection and survival, as conventional surgical metastasectomy. The great advantage is the possibility of limiting the damage to the lung. Stapler resection of a high number of metastases would mutilate the lung.

PURPOSE: Chronic asthenia (CA) is complained by some patients that have undergone thyroid surgery. We evaluate its impact in patients undergoing unilateral or bilateral thyroidectomy, the trend during a 1-year follow-up, and the possible risk factors. METHODS: A prospective, cohort study was carried out on 263 patients scheduled for thyroidectomy from 2012 and 2014. Exclusion criteria were as follows: Graves' disease, malignancies requiring radioiodine therapy, post-surgical hypoparathyroidism, laryngeal nerve palsy, abnormal pre- and post-operative thyroid hormone levels, and BMI outside the normal range. Demographics; smoking and alcoholism addiction; cardiac, pulmonary, renal, and hepatic failure; diabetes; anxiety; and depression were recorded. The Brief Fatigue Inventory (BFI) was used to evaluate CA and its possible association with these comorbidities 6 and 12 months after thyroidectomy. RESULTS: One hundred seventy-seven patients underwent total thyroidectomy (TT), 54 hemithyroidectomy (HT). Thirty-two patients were not recorded because of the onset of exclusion criteria. In the 6 months after thyroidectomy, in the TT group, 64 patients (36.16%) reported an impairment in the BFI score and only 1 in the TL group. The mean BFI score changed from 1.663(±1.191) to 2.16 (±11.148) in the TT group, from 1.584 (±1.371) to 1.171 (±1.093) in the TL group (p < 0.001). No further significant variations in BFI were reported 1 year after surgery. CONCLUSIONS: CA worsened after TT, but not after HT. Apart from operative procedure itself, no other risk factor was found be significantly associated with post-thyroidectomy asthenia. Further investigation is needed to determine the causes of CA.

Topical hemostatic agents that can seal tissues and assist in the coagulation cascade of patients undergoing surgery have been readily available for several decades. Using either synthetic or animal/plant-derived materials, these agents represent a powerful tool to reduce postoperative bleeding complications in cases where mechanical or energy-driven hemostasis is not possible or insufficient. Recently, a novel sealing hemostatic patch, HEMOPATCH (Baxter International, Deerfield, IL), was developed. The device is a thin and flexible patch consisting of a specifically-formulated porous collagen matrix, coated on one side with a thin protein-binding layer. This gives the patch a dual mechanism of action, in which the two components interact to achieve hemostasis by sealing off the bleeding surface and initiating the body's own clotting mechanisms. Here we present a series of case reports that outline the quick, effective hemostatic sealing of HEMOPATCH in a variety of clinical applications, including solid organ, gastrointestinal, biliopancreatic, endocrine, cardiovascular, and urologic surgeries. Essentially a feasibility study, these reports demonstrate how HEMOPATCH can be applied to seal almost any bleeding surface encountered during a range of procedures. Our results show that the device is eminently capable in both via laparotomy and laparoscopic approaches, and in patients with impaired coagulation or highly variable anatomies. In conclusion, our cases document the ease-of-use, application, and immediate hemostatic effect of the patch across a broad range of surgical settings and paves the way for future randomized clinical trials with more extensive follow-up.
RESUMO
Background: Voice and swallowing problems are frequently associated with thyroidectomy. Intermittent nerve monitoring (i-IONM) seems to provide a positive effect in reducing its prevalence. The aim of this study was to test the hypothesis that continuous intraoperative nerve monitoring (c-IONM) may reduce the prevalence of these disorders even further than i-IONM. Methods: This 3-arm prospective bi-institutional study compared 179 consecutive patients that underwent thyroidectomy: 56 without IONM, 55 with i-IONM and 67 with c-IONM. Neck dissections and laryngeal nerve palsies were excluded. Two questionnaires (VHI-10 for voice disorders and EAT-10 for swallowing disorders; both validated for Italian language use) were administered before and 1 month after surgery. Statistical significance was analyzed by the chi-squared test. Results: After thyroidectomy, no statistically significant differences were found in the three groups concerning EAT-10. although these symptoms seemed to be influenced by gastro-esophageal reflux. VHI-10 worsened in the "no-IONM" group compared with both i-IONM (p < 0.09, not quite statistically significant) and c-IONM (p < 0.04). Conclusion: Both i- and c-IONM improve voice quality independently of laryngeal nerve integrity. Reduced dissection and particularly restrained manipulation could explain these results, being particularly favorable for c-IONM.
RESUMO
INTRODUCTION: Dysphagia and hoarseness are possible complications that can be observed in patients undergoing thyroidectomy or other neck surgery procedures. These complaints are usually related to superior and inferior laryngeal nerves dysfunction, but these can appear even after uncomplicated surgical procedure. METHODS: We reviewed the current literature available on MEDLINE database, concerning the swallowing disorders appearing after the thyroidectomy. The articles included in the review reported pathophysiology and diagnostic concerns. RESULTS: Twenty articles were selected for inclusion in the review. Depends on the possible causes of the difficulty swallowing (related to nerve damage or appearing after uncomplicated thyroidectomy), different types of diagnostic procedures could be used to study patient discomfort, as well as intraoperative nerve monitoring, fiber optic laryngoscopy, endoscopy, pH monitoring, esophageal manometry and videofluorography. Among all these procedures, videofluorography is considered the gold standard to evaluate the entire swallowing process, since that allows a real-time study of all the three phases of swallowing: oral phase, pharyngeal phase and esophageal phase. CONCLUSION: The diagnostic procedures described can help to identify the mechanisms involved in swallowing disorders, with the aim to choose the best therapeutic option. More studies are needed for understanding the causes of the dysphagia appearing after thyroidectomy.

BACKGROUND: Prophylactic, compartment-oriented central neck dissection (CND) for cN0 papillary thyroid carcinoma (PTC) is not widely practiced. We examined our results with this surgical approach. METHODS: A cohort of 158 patients operated on for the classical variant of PTC at a follow-up of 1-22 years (mean: 6.6) were enrolled. The patients with a preoperative diagnosis of cN0 PTC (group A, 59 patients) underwent total thyroidectomy (TT) + CND. In the patients with incidental postoperative diagnosis of malignancy (group B, 99 patients) a TT alone was performed. RESULTS: Ninety-six T1, 36 T2, 26 T3/T4 PTC patients were enrolled. The overall biochemical/scintigraphic recurrence rate (15 patients, 9.49%), was significantly higher in group B. Disease-free survival and need for postoperative radioiodine ablative treatment were more favorable in group A (P<0.05; P<0.001, respectively). The median radioiodine ablative treatment in the T2 cluster alone was lower in group A (P<0.001). The morbidity rate was similar in both groups. CONCLUSION: Considering the acceptable morbidity, prophylactic CND seems to be advantageous in terms of recurrence rate and need for radioiodine treatment in this variant of PTC, at least in T2 or more advanced stages. The indolent behavior of PTC does not allow for reliable prognostic evaluations.

AIM: Hydatid disease is a parasitic disease considered endemic in many parts of the world such as South America, Middle East, Africa, Australia and the Mediterranean regions. Liver and lung hydatid disease accounts for 90% of all echinococcal cysts. Primary hydatid disease of subcutaneous sites is rare and the subcutaneous localization of a solitary hydatid cyst accounts for 1.6%. Not enough data exist for this localization, and only many heterogeneous data are described in order to define this rare condition. MATERIAL OF STUDY: We present the case of a 68-year-old-woman affected by a mass in upper-medial side of her right thigh with a 12-year-growing history. Anamnestic data were accurately collected. Many different radiological and specific serum tests were performed in order to define the diagnosis. Surgical approach was decided in order to excide the mass, and a 6-months follow-up was performed. CONCLUSIONS: Hydatid disease is common in endemic area but uncommon localizations, as in subcutaneous tissues, are a rare condition. Scientific Community lacks of complete and homogeneous data about the approach to this manifestation of the disease. Would be useful a complete review of the literature in order to plan guide-lines for the treatment of uncommon localization. KEY WORDS: Echinococcosis, Hydatid cyst, Subcutaneous localization.

INTRODUCTION: The treatment of primary hyperparathyroidism consists almost exclusively in the parathyroidectomy. The preoperative imaging (ultrasonography, 99mTc sestamibi scan) can allow to localize the pathologic gland and perform minimally-invasive focused techniques, but in presence of ectopic or intrathyroidal glands, parathyroid hyperplasia or coexistent thyroid disease, the sensitivity of these imaging techniques worsens. The present study shows a new technique of preoperative scintigraphic imaging and describes the early applications of this technique investigating if it is useful in improving the localization of the pathologic parathyroid. METHODS: Five female patients were enrolled in the study. In all cases, we performed a parathyroidectomy using a systematic recognition of the four parathyroid glands under intraoperative PTH monitoring, adding the use of the intraoperative gamma camera to usual surgical procedures. We evaluate the concordance of the results of the intraoperative gamma camera with the preoperative diagnosis, the intraoperative PTH monitoring and the intraoperative findings. Moreover, the results of the treatment one month after the surgical procedure were also considered. RESULTS: The results of intraoperative scintigraphy were always concordant with intraoperative findings. The intraoperative PTH monitoring and the results of the follow-up confirmed the completeness of the excision, at least in a short period of observation. CONCLUSIONS: The intraoperative gamma camera could help to improve the localization of a pathologic parathyroid gland. These results could be useful in improving the results of minimally invasive surgery as well as "difficult" situations.

AIM: In this paper we discuss the Neurosurgical Training Programme (NTP) in some European countries. MATERIAL AND METHODS: Although there is no official data on how many neurosurgeons are certified in Europe, our calculation shows that this number is somewhat lower than in the United States of America and even 3 times lower than in Japan (per 100.000 population). It is also evident that there is no consensus in the Programme duration or in the official NTP content, despite the recommendations of the EANS (The European Association of Neurosurgical Societies). Trainees from outside the European Union (EU) are under-represented in the EANS training courses. We believe that in the eastern part of Europe there is the most space for improvement in neurosurgical training. Solving of all these problems requires first and foremost their recognition and consideration - then devising a solution. CONCLUSION: The purpose of this paper is to compare and contrast several NTP's in Europe in order to promote a more coherent medical education. Some remarks and suggestions from the perspective of young neurosurgeons are given.
