    AbstractBackground and aimEvidence base data have demonstrated that video-assisted thyroidectomy (VAT) has good results regarding safety, morbidity, patient cure rate, pain and cosmesis. Aim of this study was to evaluate the performance of VAT in an ambulatory setting (i.e. one-day surgery, <24-h stay).Materials and methodsBetween September 2007 and July 2008, 43 patients underwent VAT in a one-day surgery division. Patient selection criteria for VAT were: thyroid nodules <30mm, gland volume <20ml, no history of thyroiditis or neck surgery or irradiation, “low risk” papillary carcinoma and absence of enlarged lymph nodes. One-day surgery patient selection criteria were medical and social logistic (Materazzi G, et al. Eur Surg Res 2007;39:182–8). Intraoperative neuromonitoring (IONM) was used for RLN identification. Intact parathyroid hormone (iPTH) levels were determined early postoperatively at +6-h. Postoperative complications, conversion rate were analyzed.ResultsNo cases required conversion to open surgery or ordinary recovery (i.e. >24h). Incidence of temporary hypoparathyroidism was 11.6% (5/43) with no case of symptomatic hypocalcemia. Incidence of temporary RLN injury was 2.3% (1 patient) with no case of permanent or bilateral RLN injury. All patients were satisfied with the type of recovery.ConclusionsThis preliminary report is an example of the safe incorporation between new technologies (IONM, early iPTH measurement) with improvement of the quality and safety of VAT performed in a one-day surgery setting

    Postoperative laryngoscopy in thyroid surgery: proper timing to detect recurrent laryngeal nerve injury

    BACKGROUND: There is currently a lack of consensus to support the proper timing for postoperative laryngoscopy that is reliable to diagnose recurrent laryngeal nerve palsy (RLNP) after thyroid surgery. The purpose of this study was to investigate the impact of different time intervals of fiber-optic nasolaryngoscopy (FNL) on the diagnosis of RLNP. METHOD: FNL was performed postoperatively at day 0 (T1), at second day post-op (T2), and +2 weeks (T3). For patients with RLNP, repeated examinations were performed at +2 (T4), +6 (T5), and +12 months (T6). RESULTS: Four hundred thirty-four patients appear for postoperative FNL, providing 825 nerves at risk. Permanent RLNP occurred in 0.7%, temporary RLNP in 6.7%. RLNP rate was 6.4% at T1, 6.7% at T2, 4.8% at T3, 2.5% at T4, 0.8% at T5, and 0.7% at T6. Full recovery of vocal cord function was confirmed after rehabilitation in 87.5% of cases at T5 and 89% in T6. T2 was significantly superior to T3 in terms of diagnosis of RLNP (P < 0.05). Of patients at T2, 10.7% did not see any reason to FNL because of their normal voice register. CONCLUSION: FNL is essential for the detection of vocal cord paralysis after thyroidectomy. We report different time evaluation criteria of vocal cord motility with great and significant variability of results. Second day post-op inspection of the larynx (T2) is suggested. Symptomatic voice assessment is insufficient

    Neuroendocrine carcinomas of the breast

    INTRODUCTION: Neuroendocrine (NE) breast cancers encompass a heterogeneous group of tumours showing morphological features similar to those of NE neoplasms of the gut and lung and expressing one or more neuroendocrine markers (neuron specific enolase, chromogranins synaptophysin) in at least 50% of tumour cells. They are rare lesions representing about 2-3% of all breast cancers and affecting more frequently elderly patients. AIM: Prospective observational study is to analyse the clinico-pathological aspects of NE carcinomas of the breast undergone surgical resection compared to breast carcinomas with a minor neuroendocrine component and to conventional invasive ductal or lobular cancers. MATERIAL AND METHOD: Thirty-five consecutive breast carcinomas showing morphological features suggestive of an endocrine differentiation were selected among breast cancers undergone surgical treatment during the period of January 1979-December 2004. RESULTS: The 35 patients were divided into two categories: 13 neuroendocrine carcinomas (NECs) and 22 ductal carcinomas with a minor neuroendocrine component (DC-NE). The average follow-up was 60 months. The patients with CNE developed breast cancer in an advanced age compared to the patients with infiltrating ductal carcinoma NAS or infiltrating lobular carcinoma. We did not find recurrent disease in the NEC group, while it was observed in 2 patients (9%) with DC-NE, in 6 cases (17%) with infiltrating ductal carcinoma NAS and in 7 cases (20%) with infiltrating lobular carcinoma. DISCUSSION: The CNE compared with the infiltrating ductal and lobular carcinoma are statistically different in relation to the expression of the receptor of c-erb-B2, p53, progesterone, for the lymph node state at diagnosis and the risk of reappearance of breast tumour. Our study confirms the choice to consider the neuroendocrine carcinoma of the breast as a separate histological group and seems to suggest a less aggressiveness of this type of tumou

    Dissection and hemostasis with hydroxilated polyvinyl acetal tampons in open thyroid surgery

    BACKGROUND: The essential objectives for thyroidectomy are: avoidance of injury to the recurrent laryngeal nerves, conservation of the parathyroid glands, an accurate haemostasis and an excellent cosmesis. In the last 10 years major improvements and new technologies have been proposed and applied in thyroid surgery; among these mini-invasive thyroidectomy, regional anaesthesia and intraoperative neuromonitoring, and new devices for achieving dissection and haemostasis. Minor bleeding from small vessels could be a major complication in thyroid surgery. The purpose of ligating vessels is to maintain the surgical site free from an excess of blood and reduce blood loss in the patient. MATERIALS AND METHODS: Hydroxylated polyvinyl acetal tampons (HPA) are made by a synthetic, open cell foam structure able to absorb fluids up to 25 times the initial weight. We tested their efficacy for small bleeding control and tissue dissection during several thyroid procedures. RESULTS: HPA tampons have been found extremely useful to absorb blood coming from minor and diffuse loss, helping to control bleeding by a combined action of fluid absorption and local compression. The porous design of the tampon allows the use of the suction device right through the tampon itself. Thanks to the initial mildly hard consistency, we also used HPA tampons as dissecting instruments. CONCLUSION: In our experience the use of HPA tampons resulted extremely efficient for minor bleeding control, fluids removal and tissue dissection during thyroid surgery

    Cervico-mediastinal schwannoma of the vagus nerve: resection with intraoperative nerve monitoring.

    Schwannomas are usually benign, single, encapsulated, slow-growing tumours originating from cranial or spinal nerve sheaths. The vagus nerve involvement at the mediastinal inlet is very uncommon. For anatomical reasons, the resection of cervical and mediastinal schwannoma of the vagus nerve has a high risk of vocal fold paralysis. We describe the case of a 67-year-old female with a cervico-mediastinal schwannoma of the vagus nerve that we removed using the intraoperative neuromonitoring technique. The patient presented with mild hoarseness and complained of discomfort behind the jugular notch. Neck and chest computerized tomography described a 35 9 30 mm solid lesion behind the left clavi-sternal junction; preoperative fine needle aspiration cytology revealed schwannoma. Resection of the mass was performed with a cervical approach and the vagus nerve tumour was completely removed under continuous neuromonitoring (NIM-3 System), preserving the vagus and the recurrent laryngeal nerve function. Pathology on the resected mass documented A-type schwannoma with \u2018\u2018ancient schwannoma\u2019\u2019 areas. The intraoperative neurostimulation and neuromonitoring approach for the resection of vagus schwannoma are recommended because it may reduce the risk of injury to the vagus and to the recurrent laryngeal nerve
