AAIH should be always suspected when chest swelling occurs after a minor or major trauma, and CT must be promptly performed to rule out diaphragmatic or abdominal viscera injury. This condition requires surgery to prevent serious complications, the first-choice technique should be mesh tension-free repair.

Background: Being the thyroid gland a highly vascularized organ, achieving a meticulous hemostasis is essential to avoid serious complications. Currently, energy-based devices are widely used in thyroid surgery.The aim of this study was to compare Harmonic Focus (HF), LigaSure Small Jaw (LSJ) and Thunderbeat Open Fine Jaw (TB) in terms of surgical outcomes and complications.Methods: Patients undergoing thyroidectomy in our Unit between January 2012 and June 2018 were retrospectively analyzed. According to the type of energy-device used, patients were divided into three groups: Group A (HF), Group B (LSJ) and Group C (TB).Results: A total of 1,165 patients were included in this study: 1,012 in Group A, 96 in Group B and 57 in Group C. Demographic data and histopathological findings were comparable between the three groups. About the postoperative stay and complications, no statistically significant difference was found.The mean operative time was 89.41±20.60 minutes in Group A, 85.57±15.91 minutes in Group B and 78.07±17.67 minutes in Group C (P<0.01). However, the post-hoc test for all pairwise comparisons showed a statistically significant difference only between Group A and Group C.Conclusions: HF, LSJ and TB have proved to be safe and effective. The postoperative stay and complications were comparable between the three groups. Considering the limits of our investigation, further studies are needed to investigate the effect of TB on operative times.

The outbreak of the COVID-19 pandemic has led to a disruption of surgical care. The aim of this multi-centric, retrospective study was to evaluate the impact of the pandemic on surgical activity for thyroid disease among the Italian Units of Endocrine Surgery. Three phases of the pandemic were identified based on the epidemiological situation and the public measures adopted from the Italian Government (1st phase: from 9th March to 3rd May 2020; 2nd phase: from 4th May to 14th June; 3rd phase: from 15th June to 31st). The patients operated upon during these phases were compared to those who underwent surgery during the same period of the previous year. Overall, 3892 patients from 28 Italian endocrine surgical units were included in the study, 1478 (38%) operated upon during COVID-19 pandemic, and 2414 (62%) during the corresponding period of 2019. The decrease in the number of operations was by 64.8%, 44.7% and 5.1% during the three phases of COVID-19 pandemic, compared to 2019, respectively. During the first and the second phases, the surgical activity was dedicated mainly to oncological patients. No differences in post-operative complications were noted between the two periods. Oncological activity for thyroid cancer was adequately maintained during the COVID-19 pandemic.

Introduction: Papillary thyroid microcarcinoma (PTMC) is defined as a tumor with a larger diameter ≤ 1 cm and is considered having an indolent course and an excellent prognosis. Nevertheless, the incidence of lymph node metastasis in PTMC is not negligible, reaching up to 65% in some series. The aim of this study was to assess the incidence of lymph node metastasis in patients with PTMC and to evaluate predictive factors for lymph node metastasis. Methods: We included in this retrospective observational study patients who underwent thyroidectomy with pathological diagnosis of PTMC at our department from January 2003 to June 2019. Results: Two hundred ninety-three patients were included in the study. The incidence of lymph node metastasis was 13.7%. Multivariate analysis revealed as independent risk factors for lymph node metastasis age <45 years, nodule size ≥6 mm, tall cell variant of PTC, extrathyroidal extension, and angioinvasion. Conversely, autoimmune thyroiditis was found as a protective factor for lymph node metastasis. A subgroup of patients, with nodule size ≤ 5 mm, presented non-aggressive features. Conclusion: The incidence of lymph node metastasis in PTMC is considerable; the size of the tumor appears to be the most significant predictive factor for lymph node metastasis. The traditional cut-off value used for definition of microcarcinoma could be reconsidered to identify patients with an indolent course of the tumor, where active surveillance could be the appropriate treatment, and on the other hand, patients with potentially aggressive tumors requiring an adequate surgical intervention. Clinical Trial Registration: The trial was registered at ClinicalTrials.gov (ID: NCT04274829).
