Parathyroid Retrospective Analysis of Neoplasms Incidence (pTRANI Study): An Italian Multicenter Study on Parathyroid Carcinoma and Atypical Parathyroid Tumour. J Clin Med 2023; 12:6297. [PMID: 37834940 PMCID: PMC10573774 DOI: 10.3390/jcm12196297] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 09/15/2023] [Accepted: 09/24/2023] [Indexed: 10/15/2023] Open
Abstract
BACKGROUND Parathyroid cancer (PC) is a rare sporadic or hereditary malignancy whose histologic features were redefined with the 2022 WHO classification. A total of 24 Italian institutions designed this multicenter study to specify PC incidence, describe its clinical, functional, and imaging characteristics and improve its differentiation from the atypical parathyroid tumour (APT). METHODS All relevant information was collected about PC and APT patients treated between 2009 and 2021. RESULTS Among 8361 parathyroidectomies, 351 patients (mean age 59.0 ± 14.5; F = 210, 59.8%) were divided into the APT (n = 226, 2.8%) and PC group (n = 125, 1.5%). PC showed significantly higher rates (p < 0.05) of bone involvement, abdominal, and neurological symptoms than APT (48.8% vs. 35.0%, 17.6% vs. 7.1%, 13.6% vs. 5.3%, respectively). Ultrasound (US) diameter >3 cm (30.9% vs. 19.3%, p = 0.049) was significantly more common in the PC. A significantly higher frequency of local recurrences was observed in the PC (8.0% vs. 2.7%, p = 0.022). Mortality due to consequences of cancer or uncontrolled hyperparathyroidism was 3.3%. CONCLUSIONS Symptomatic hyperparathyroidism, high PTH and albumin-corrected serum calcium values, and a US diameter >3 cm may be considered features differentiating PC from APT. 2022 WHO criteria did not impact the diagnosis.

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.

Is the Adrenal Incidentaloma Functionally Active? An Approach-To-The-Patient-Based Review. J Clin Med 2022; 11:jcm11144064. [PMID: 35887828 PMCID: PMC9323753 DOI: 10.3390/jcm11144064] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 07/01/2022] [Accepted: 07/10/2022] [Indexed: 02/01/2023] Open
Abstract
Adrenal incidentalomas are a common occurrence. Most of them are adrenocortical adenomas that do not cause harm and do not require surgery, but a non-negligible proportion of incidentalomas is represented by functionally active masses, including cortisol-secreting adenomas (12%), pheochromocytomas (3–6%), aldosterone-secreting adenomas (2–3%), as well as malignant nodules, such as adrenocortical carcinomas (2–5%), which can be either functioning or non-functioning. All patients with an adrenal incidentaloma should undergo a few biochemical screening and confirmatory tests to exclude the presence of a functionally active mass. In this approach-to-the-patient-based review, we will summarize current recommendations on biochemical evaluation and management of functionally active adrenal incidentalomas. For this purpose, we will present four case vignettes, whereby we will describe how patients were managed, then we will review and discuss additional considerations tied to the diagnostic approach, and conclude with practical aspects of patient perioperative management. To improve the perioperative management of patients with functional adrenal incidentalomas, multidisciplinary meetings are advocated.

Autofluorescence of parathyroid glands during endocrine surgery with minimally invasive technique. J Endocrinol Invest 2022; 45:1393-1403. [PMID: 35262861 DOI: 10.1007/s40618-022-01774-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Accepted: 02/18/2022] [Indexed: 10/18/2022]
Abstract
PURPOSE Accidental injury to the parathyroid glands (PTGs) is common during thyroid and parathyroid surgery. To overcome the limitation of naked eye in identifying the PTGs, intraoperative autofluorescence imaging has been embraced by an increasing number of surgeons. The aim of our study was to describe the technique and assess its utility in clinical practice. METHODS Near-infrared (NIR) autofluorescence imaging was carried out during open parathyroid and thyroid surgery in 25 patients (NIR group), while other 26 patients underwent traditional PTG detection based on naked eye alone (NO-NIR group). Primary variables assessed for correlation between traditional approach and autofluorescence were number of PTGs identified and incidence of postoperative hypoparathyroidism (hypoPT). RESULTS 81.9% of PTGs were detected by means of fluorescence imaging and 74.5% with visual inspection alone, with an average of 2.72 PTGs visualized per patient using NIR imaging versus approximately 2.4 per patient using naked eye (p = 0.38). Considering only the more complex total thyroidectomies (TTs), the difference was almost statistically significant (p = 0.06). Although not statistically significant, the observed postoperative hypoPT rate was lower in the NIR group. CONCLUSION Despite the limitations and technical aspects still to be investigated, fluorescence seems to reduce this complication rate by improving the intraoperative detection of the PTGs.

Abstract
Context Aortic stiffness is an emerging predictor of cardiovascular morbidity and mortality. Current data about the effect of subclinical and overt thyroid hormone disorders on aortic stiffness are often conflicting. Objective Primary outcome was to investigate if subclinical and overt thyroid hormone disorders were associated with aortic stiffness. Secondary outcome was to identify disease effect modifiers. Methods Data sources were PubMed, Google Scholar, SCOPUS, Web of Sciences, and the Cochrane Library. Eligible studies included reports of pulse wave velocity (PWV), which is the gold standard method for measuring aortic stiffness, in patients with subclinical and overt thyroid disorders. Two investigators independently identified eligible studies and extracted data. Pooled mean difference was the summary effect measure. Data were presented in forest plots with outlier and influential case diagnostics. Univariate meta-regression analysis was used to identify effect modifiers. Results Eleven observational studies were selected, including 1239 patients with subclinical hypothyroidism, 81 patients with overt hypothyroidism, 338 patients with thyrotoxicosis, and 12 715 controls. PWV was significantly higher in subclinical (P < .001) and overt hypothyroidism (P < .001), as well as in patients with thyrotoxicosis (P = .027) compared with controls. Age was an effect modifier in hypothyroid patients. Conclusion This study shows that both overt and subclinical hypothyroidism as well as thyrotoxicosis were associated with an increase of aortic stiffness. The impact of treatment of these conditions on aortic stiffness should be assessed in clinical trials.

Hemithyroidectomy versus total thyroidectomy in the intermediate-risk differentiated thyroid cancer: the Italian Societies of Endocrine Surgeons and Surgical Oncology Multicentric Study. Updates Surg 2021; 73:1909-1921. [PMID: 34435312 DOI: 10.1007/s13304-021-01140-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Accepted: 05/26/2021] [Indexed: 11/27/2022]
Abstract
The surgical treatment of the intermediate-risk DTC (1-4 cm) remains still controversial. We analyzed the current practice in Italy regarding the surgical management of intermediate-risk unilateral DTC to evaluate risk factors for recurrence and to identify a group of patients to whom propose a total thyroidectomy (TT) vs. hemithyroidectomy (HT). Among 1896 patients operated for thyroid cancer between January 2017 and December 2019, we evaluated 564 (29.7%) patients with unilateral intermediate-risk DTC (1-4 cm) without contralateral nodular lesions on the preoperative exams, chronic autoimmune thyroiditis, familiarity or radiance exposure. Data were collected retrospectively from the clinical register from 16 referral centers. The patients were followed for at least 14 months (median time 29.21 months). In our cohort 499 patients (88.4%) underwent total thyroidectomy whereas 65 patients (11.6%) underwent hemithyroidectomy. 151 (26.8%) patients had a multifocal DTC of whom 57 (10.1%) were bilateral. 21/66 (32.3%) patients were reoperated within 2 months from the first intervention (completion thyroidectomy). Three patients (3/564) developed regional lymph node recurrence 2 years after surgery and required a lymph nodal neck dissection. The single factor related to the risk of reoperation was the histological diameter (HR = 1.05 (1.00-1-09), p = 0.026). Risk stratification is the key to differentiating treatment options and achieving better outcomes. According to the present study, tumor diameter is a strong predictive risk factor to proper choose initial surgical management for intermediate-risk DTC.

Abstract
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.

Abstract
BACKGROUND Primary hyperparathyroidism (pHPT) is a common endocrine disorder, due to an excessive secretion of parathyroid hormone (PTH) from one or more parathyroid gland(s), where the only cure remains surgery. The surgical approach has become less invasive over the years, thanks to the advances in the preoperative localization of the enlarged parathyroid gland, as well as to the possibility to measure intra-operative parathyroid hormone (IOPTH). After the targeted removal of a parathyroid gland, IOPTH can confirm biochemically the cure of pHPT, such that it helps the surgeon to judge if the parathyroidectomy has been successful and there is no need of additional dissection. As with all laboratory tests, the quality of IOPTH total testing process is essential to the best utilization of patients' results. However, this can be affected by errors occurring in different phases. This review aims to describe the total testing process of IOPTH. METHODS We performed a search in Pubmed and a review of the literature on the current management of pHPT and the total testing process of IOPTH measurement. RESULTS Compared to previous studies focusing on single aspects of the IOPTH testing process, here we have analyzed all the steps crucial for the quality of IOPTH from the "pre-pre" to the "post-post" analytical phase. CONCLUSIONS Clinicians and laboratory scientists should be aware of all the potential sources of errors in IOPTH measurement in order to improve their daily management of pHPT.

Abstract
PURPOSE Aim of the study was to assess the impact of the Italian Society of Anatomic Pathology and Diagnostic Cytology (SIAPEC) classification of 2014, on the treatment of indeterminate thyroid lesions (TIR3). METHODS We retrospectively analyzed patients undergoing thyroid surgery for TIR3 lesions between 2013 and 2018, at the General Surgery Department of Trieste University Hospital. According to the SIAPEC classification, patients were divided into TIR3A and TIR3B groups. All patients treated before 2014 underwent surgical treatment, and surgical specimens were retrospectively classified after revision of fine-needle aspiration cytology. Starting 2014, TIR3A patients were treated only when symptomatic (i.e., coexistent bilateral thyroid goiter or growing TIR3A nodules), whereas TIR3B patients always received surgical treatment. Hemithyroidectomy (HT) was the procedure of choice. Total thyroidectomy (TT) was performed in case of concurrent bilateral goiter, autoimmune thyroid disease, and/or presence of BRAF and/or RAS mutation. Lastly, we analyzed the malignancy rate in the two groups. RESULTS 29 TIR3A and 90 TIR3B patients were included in the study. HT was performed in 10 TIR3A patients and 37 TIR3B patients, respectively, with need for reoperation in 4 TIR3B (10.8%) patients due to histological findings of follicular thyroid carcinoma >1 cm. The malignancy rates were 17.2% in TIR3A and 31.1% in TIR3B, (p = 0.16). Predictability of malignancy was almost 89% in BRAF mutation and just 47% in RAS mutation. CONCLUSIONS The new SIAPEC classification in association with biomolecular markers has improved diagnostic accuracy, patient selection, and clinical management of TIR3 lesions.

Initial Ablation Ratio Predicts Volume Reduction and Retreatment After 5 Years From Radiofrequency Ablation of Benign Thyroid Nodules. Front Endocrinol (Lausanne) 2020; 11:582550. [PMID: 33597921 PMCID: PMC7883676 DOI: 10.3389/fendo.2020.582550] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2020] [Accepted: 12/14/2020] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Radiofrequency ablation (RFA) has gained ground as an effective and well-tolerated technique to treat benign thyroid nodules. Most of the available studies have described the short-term outcomes of RFA, whereas there is a limited number of studies evaluating long-term issues, such as regrowth and the likelihood of retreatments. In addition, risk markers of regrowth and retreatment remain to be defined. The initial ablation ratio (IAR) is an index that measures the amount of ablation after RFA, which has been associated with technique efficacy (i.e. volume reduction >50% after 1 year from the procedure). This study aimed at evaluating i) IAR reproducibility and ii) IAR predictive value for RFA 5-year outcomes. MATERIALS AND METHODS This is a retrospective single center study on patients with benign thyroid nodules treated with RFA and followed for 5 years after initial treatment. IAR interobserver reproducibility was evaluated with Bland-Altman method and Lin's concordance correlation coefficient (ρc). IAR predictive value for RFA 5-year outcomes was evaluated with linear and logistic regression models, as well as with Cox models, while receiver operating characteristic (ROC) analyses were used for cut-offs. RESULTS We selected 78 patients with 82 benign thyroid nodules. The procedure significantly reduced nodule volume and this reduction was generally maintained over time. Technique efficacy was achieved in 92% of patients, while 23% of nodules regrew and 12% of nodules were retreated. Median IAR was 83%. Lin's concordance and Pearson's correlation coefficients suggested a good interobserver reproducibility of this index, consistent with the limits of agreement of the Bland-Altman plot. IAR was significantly associated with technique efficacy, 1- and 5-year volume reduction ratio, and with the likelihood of a retreatment, but not with nodule regrowth. ROC analyses showed that IAR cut-off was 49% for technique efficacy and 73% for retreatment. CONCLUSIONS Our results show for the first time that IAR is reproducible and that it predicts the volume reduction and the likelihood of a retreatment after 5 years from RFA.

Abstract
AIM The aim of our study was to assess if there were any differences in clinical presentation, management, and outcome, between younger and elderly patients with acute diverticulitis (AD). MATERIAL OF STUDY 279 patients with diagnosis of AD treated at the General Surgery Department of Trieste from January 2007 to December 2015 were retrospectively examined and then followed for a minimum of 4 years. We divided patients in two categories: young ≤ 50 years and elderly > 50. Gender, American Society of Anesthesiologists status (ASA score), Hinchey's stage, type and timing of surgery, morbidity, length of hospital stay, recurrence, and overall mortality were retrospectively analyzed. RESULTS There were 279 patients, 64 (22,9 %) were young and 215 (77,1%) were elderly. Female gender was more frequent in elderly cohort (150 pts 69,7 % F vs 65 pts 30,3 % M) than in the young (16 pts, 25% F vs 48 pts, 75% M), (p<0,001). Higher ASA scores were registered in elderly patients with statistically significant correlation with Hinchey's stage. 229 patients ( 82,07 %) received as initial treatment antibiotic therapy (conservative treatment), 50 (17,93 %) pts underwent EM-S, and 11 underwent to DEL-S. DISCUSSION In our experience, none significant differences were recorded about Hinchey's stage, timing of surgery, morbidity, length of hospital stay, and recurrence; whereas, regarding the type of surgery (resection-anastomosis (R-A), Hartmann's procedures, and Lavage/Drainage) there were a significant difference (p=0,04). CONCLUSIONS Hartmann's procedures have been effectuated more frequently in the elderly than in the young with recanalization in less than half of elderly. These data seems to confirm that there is no significant difference in incidence or the natural course of acute and complicated colonic diverticulitis among the young or the elderly. The best surgical treatment, with the least morbidity, may be resection with primary anastomosis. KEY WORDS Diverticular Disease, Elderly Patients, Sigmoidectomy, Young Patients.

Abstract
BACKGROUND The relationship between breast cancer (BC) and thyroid disease (TD) is still controversial. The aim of the study was to investigate the possible coexistence of TD in patients with newly diagnosed BC and its correlation with BC clinical presentation with regard to menopausal status and stage of disease. METHODS This is a retrospective cohort study of all patients treated for primary BC between 2014 and 2016 at the Breast Unit of Trieste University Hospital. Clinical charts and reports were reviewed for coexisting thyroid disorders (i.e. hyperthyroidism, hypothyroidism, benign TD, thyroid cancer, thyroid autoimmunity) and menopausal status at the time of BC diagnosis. Biomolecular profile, stage, and grading of BC were also evaluated. RESULTS A total of 786 women and 7 men were included in the study. Co-presence of TD was found in 161(20.3%) cases: of these, 151(19.4%) patients presented benign TD and 10(1.3%) patients presented thyroid carcinoma. Thyroid autoimmunity was found in 51(32%) patients. Regarding thyroid function, 88(55%) patients had hypothyroidism, 19(12%) hyperthyroidism, and 54(33%) normal thyroid function. No statistically significant correlation was found between age and TD (p = 0.16), although TD was more common in women aged ≥60 years. Women with BC diagnosed at pre-menopausal age were more likely to have thyroid autoimmune diseases (45% vs. 29%, p = 0.05). No association was detected among BC molecular profiles with either thyroid autoimmunity (p = 0.26) or altered thyroid function (p = 0.63). High-grade BC was more frequent in women with hyperthyroidism (52.9%, p = 0.04), but the grading was independent from the presence of thyroid autoimmune disease (p = 0.87). BC stage was related to both thyroid autoimmunity (p = 0.04) and thyroid function (p < 0.001), with 55.2% of women affected by benign TD presenting with stage I BC and more aggressive BCs found in hypothyroid patients. CONCLUSIONS According our study results, patients with primary BC present a greater incidence of autoimmunity disorders, especially when diagnosed in the pre-menopausal setting. However, further prospective studies are required to definitively prove causality.

Touch Imprinting Cytology may be useful in the intraoperative evaluation of the sentinel lymph node in melanoma. Ann Ital Chir 2019; 90:491-496.

Abstract
PURPOSE The aim of the study was to assess whether the reliability of Touch Imprinting Cytology (TIC) of Sentinel lymph node biopsy (SLNB) in skin melanoma patients allows intraoperative decisions regarding simultaneous radical lymphadenectomy to be made. Previous experiences have shown that the limit of TIC in extemporaneous diagnosis was represented by the minimal deposits of the tumor. Many current data seem to show that in this situation radical lymphadenectomy is no longer necessary, so we wondered if TIC could regain importance in the intraoperative management of these patients. METHODS TIC results of Sentinel Lymph Nodes Biopsy (SLN) were compared with those of standard histopathological and immunohistochemical examinations. RESULTS A total number of 110 SLN were detected from 50 melanoma patients.TIC revealed the presence of metastases only in 1 out of 13 melanoma-positive SLN (sensitivity 7.6%). There were no false-positive results of TIC (specificity 100%). The negative predictive value was 75.5%, the positive one 100% with a total diagnostic accuracy of 76%. CONCLUSIONS TIC for SLNs is a reliable method, relatively fast and not very expensive. Although with a very high specificity, its sensitivity was very low, and almost exclusively limited to macro-metastases (>2mm). Furthermore, it was not possible to identify a subgroup of patients, based on the characteristics of the primary tumor, in which the method could have been more useful. Finally, even in positive cases, the method rarely reduced the need of a tactic in two stages, principally for the management of the operating room.

Abstract
Aims and background Primary bilateral adrenal non-Hodgkin's lymphoma is an extremely rare entity. Only 44 cases have been reported in the literature. The most common presenting symptoms are abdominal pain, fever, asthenia, constipation, weight loss or typical symptoms of adrenal insufficiency, hypertension, darkening of skin, orthostatic hypotension or an addisonian crisis. Methods The case is presented of a 57-year-old man suffering from primary bilateral adrenal lymphoma with symptoms of adrenal insufficiency syndrome associated with bilateral, stabbing lumbar pain and a palpable mass on the left side. Laboratory tests revealed a considerable increase in lactate dehydrogenase levels, adrenal insufficiency, and high corticotropin levels. Results Abdominal CT scan showed two large adrenal masses. A CT-guided fine needle aspiration biopsy revealed a large B-cell non-Hodgkin's lymphoma. Combination chemotherapy according to the CHOP protocol with cyclophosphamide, doxorubicin, vincristine and prednisolone was initiated, which caused a slight reduction in size of the two adrenal masses. The patient underwent a bilateral adrenalectomy with almost complete excision of the tumors. Replacement therapy with cortisone acetate was initiated postoperatively. Adjuvant combination chemotherapy according to the CHOP protocol was started but renal failure gradually emerged and the treatment could not be completed. The patient died seven months after surgery due to acute bronchial pneumonia and progression of disease. Conclusions Primary bilateral adrenal non-Hodgkin's lymphoma mainly affects adult men. Diagnosis is based on histological examination. Whether associated or not with radiotherapy, chemotherapy is the most recommended treatment. Surgery, where possible, seems to lead to an increase in survival rates, but it is not possible to draw any definite conclusions on its effectiveness as yet.

Rationality in prophylactic central neck dissection in clinically node-negative (cN0) papillary thyroid carcinoma: Is there anything more to say? A decade experience in a single-center. Int J Surg 2018; 41 Suppl 1:S40-S47.

Abstract
AIM Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy. Despite its extremely favorable prognosis, cervical lymph node metastases are a common feature of PTC and a known independent risk factor for local recurrence. However, the role of prophylactic central neck dissection (PCND) remains a matter of debate in patients with clinically node-negative (cN0) PTC. To better clarify the current role of PCND in the surgical treatment of PTC, evaluating advantages and disadvantages of PCND and outcome of cN0 PTC patients who have been treated with either total thyroidectomy alone or in combination with PCND. A review of recent literature data is performed. METHODS Between January 2000 and December 2015, 186 consecutive patients with cN0 PTC were identified to be included in the present study. 74 of these underwent total thyroidectomy associated with PCND, while 112 patients underwent total thyroidectomy alone. The epidemiological and clinical-pathological data of all patients included were collected at diagnosis and during follow-up. RESULTS Overall complication rate was significantly higher in the group of patients undergoing PCND (39.2% vs. 17.8%, p = 0.0006). To be specific, they presented a considerably increased risk of temporary recurrent laryngeal nerve injury (p = 0.009) and of permanent hypothyroidism (p = 0.016). Overall survival and recurrence rates did not differ between those undergoing PCND and those undergoing total thyroidectomy alone (p = 1.000 and p = 0.715, respectively). CONCLUSIONS The results of the present study do not support the routine use of PCND in the treatment of cN0 PTC patients.

Abstract
PURPOSE Surgical site infection (SSI) is the most common complication of colorectal surgery, resulting in significant burden in terms of morbidity and length of hospital stay. The aims of this study were to establish the incidence of SSI in patients undergoing colorectal surgeries and to identify potentially modifiable risk factors to reduce overall SSI rates. METHODS This retrospective study analyzed patients who underwent colorectal resection at our Department. Patients were identified using a prospective SSI database. Univariate and multivariate analyses were used to identify risk factors. RESULTS A total of 687 patients were enrolled in the study and the overall SSI rate was 19.9% (137 patients). Superficial incisional surgical site infections (SSSIs) developed in 52 (7.6%) patients, deep incisional surgical site infections (DSSIs) developed in 15 (2.2%), and organ/space infections (OSIs) developed in 70 (10.1%). Univariate and multivariate analyses confirmed that age, diabetes, emergency surgery, and a high infection risk index are risk factors for SSI. CONCLUSIONS There are some modifiable and non-modifiable risk factors for SSI. IRI and age are non-modifiable, whereas the timing of surgery and diabetes can be modulated by trying to defer some emergency procedures to elective ones and normalizing the glycemia of diabetic patients.

Abstract
PURPOSE Radiofrequency ablation has been advocated as an alternative to radioiodine and/or surgery for the treatment of autonomously functioning benign thyroid nodules. However, only a few studies have measured radiofrequency ablation efficacy on autonomously functioning benign thyroid nodules. The aim of this work was to evaluate the 12-month efficacy of a single session of radiofrequency ablation (performed with the moving shot technique) on solitary autonomously functioning benign thyroid nodules. METHODS Thirty patients with a single, benign autonomously functioning benign thyroid nodules, who were either unwilling or ineligible to undergo surgery and radioiodine, were treated with radiofrequency ablation between April 2012 and May 2015. All the patients underwent a single radiofrequency ablation, performed with the 18-gauge needle and the moving shot technique. Clinical, laboratory, and ultrasound evaluations were scheduled at baseline, and after 1, 3, 6, and 12 months from the procedure. RESULTS A single radiofrequency ablation reduced thyroid nodule volume by 51, 63, 69, and 75 % after 1, 3, 6, and 12 months, respectively. This was associated with a significant improvement of local cervical discomfort and cosmetic score. As for thyroid function, 33 % of the patients went into remission after 3 months, 43 % after 6 months, and 50 % after 12 months from the procedure. This study demonstrates that a single radiofrequency ablation allowed us to withdraw anti-thyroid medication in 50 % of the patients, who remained euthyroid afterwards. CONCLUSION This study shows that a single radiofrequency ablation was effective in 50 % of patients with autonomously functioning benign thyroid nodules. Patients responded gradually to the treatment. It is possible that longer follow-up studies might show greater response rates.

Abstract
The most appropriate surgical management of "follicular neoplasm/suspicious for follicular neoplasm" lesions (FN), considering their low definitive malignancy rate and the limited predictive power of preoperative clinic-diagnostic factors, is still controversial. On behalf of the Italian Association of Endocrine Surgery Units (U.E.C. CLUB), we collected and analyzed the experience of 26 endocrine centers by computerized questionnaire. 1379 patients, surgically treated after a FN diagnosis from January 2012 and December 2103, were evaluated. Histological features, surgical complications, and medium-term outcomes were reported. Total thyroidectomy (TT) was performed in 1055/1379 patients (76.5 %), while hemithyroidectomy (HT) was carried out in 324/1379 cases (23.5 %). Malignancy rate was higher in TT than in HT groups (36.4 vs. 26.2 %), whereas the rates of transient and definitive hypoparathyroidism following TT were higher than after HT. Consensual thyroiditis (16.8 vs. 9.9 %) and patient age (50.9 vs. 47.9 %) also differed between groups. A cytological FN diagnosis was associated to a not negligible malignancy rate (469/1379 patients; 34 %), that was higher in TT than in HT groups. However, a lower morbidity rate was observed in HT, which should be considered the standard of care in solitary lesions in absence of specific risk factors. Malignancy could not be preoperatively assessed and clinical decision-making is still controversial. Further efforts should be spent to more accurately preoperatively classify FN thyroid nodules.

Abstract
Benign thyroid nodules are an extremely common occurrence. Radiofrequency ablation (RFA) is gaining ground as an effective technique for their treatment, in case they become symptomatic. Here we review what are the current indications to RFA, its outcomes in terms of efficacy, tolerability, and cost, and also how it compares to the other conventional and experimental treatment modalities for benign thyroid nodules. Moreover, we will also address the issue of treating with this technique patients with cardiac pacemakers (PM) or implantable cardioverter-defibrillators (ICD), as it is a rather frequent occurrence that has never been addressed in detail in the literature.

Abstract
INTRODUCTION Iatrogenic ureteral injury (IUI) is a serious complication that can occur during abdominal or pelvic operations with a reported frequency in literature of approximately 0.3-1.5%. Moreover, the number of iatrogenic ureteric injuries has increased markedly during the past two decades, partly because of the introduction of laparoscopy and the overall increase in surgical procedures. MATERIAL AND METHOD The present systematic review was set up to compare the incidence of IUI between laparoscopic and open colectomies. The study also assessed the features of the ureteric injuries and their prevention and management. We conducted a search of the literature for prospective and randomized clinical trials presenting a comparison between laparoscopic and open colorectal resections performed for any indication starting from 2003 to 2015. RESULTS After an initial moderate increase in incidence of IUIs, with growing experience in laparoscopic surgery, ureteral injuries not seem to be more in laparoscopic surgery than conventional surgery. Many surgeons and gynecologists agree that prophylactic ureteral catheterization may reduce the chance of IUIs. CONCLUSIONS Ureteral injury is especially difficult to detect during laparoscopic operations, and the symptoms of ureteric injury may develop either acutely or more insidiously, depending on the mechanism of injury. These injuries, if recognized late, can result in significant morbidity with loss of renal function. Early recognition and immediate repair of ureteral injuries during the same procedure is highly desirable. A ureteral injury not recognized and treated during the same procedure may require a temporary diverting nephrostomy and secondary surgery with increased morbidity.

Abstract
AIM Aim of this study was to evaluate bowel function after colonic resection for diverticular disease and assess its impact on patients' quality of life. MATERIAL OF STUDY 47 patients who underwent urgent or elective surgery for diverticular disease were either personally contacted or interviewed by telephone and given a questionnaire. The Memorial Bowel functional index, the short form (36) health survey questionnaire, and the fecal incontinence severity index were used. RESULTS Fecal Urgency was found in 4,25% of cases, Incomplete Evacuation in 17,03%, and the Lifestyle/Diet Modification Score in 23,4% of patients. Incontinence cases were not found. After surgery we found reduction of abdominal pain (p=0.017) and improved bowel function (p=0.001). The quality of life correlated to bowel function was defined good or very good in 87.2% of cases whereas 4.3% of patients reported poor bowel function. This condition was related to female patients (p=0.02), urgent surgery (p=0.05), and to post-operative complication (p=0.05). DISCUSSION AND CONCLUSIONS In our experience, both bowel function and abdominal pain improved after surgery and 91.4% of patients were satisfied with the choice of surgery and would agree to do it again. The presence of not recognized inflammatory bowel syndromes can occasionally be responsible for persistent disorders after surgery. KEY WORDS Bowel function, Diverticular disease, Sigmoidectomy.

Abstract
AIM Cholecystectomy is among surgical procedures with the longest waiting list and a significant amount of patients waiting for surgery suffer from symptoms related to complications of cholelithiasis. The aim of this study is to evaluate the economic impact caused by waiting lists. MATERIAL AND METHODS A retrospective study was performed on patients undergoing intervention of cholecystectomy. 86 patients were included in the study. A comparative analysis was carried out among patients without complications (group A) and patients who faced complications while waiting for surgery, therefore requiring unplanned hospital admissions (group B), and patients who were operated in emergency for complications (group C). RESULTS The overall cost of health care amounted to 1.849,4 € for each patient of group A, 3.513,2 € for each patient of group B and 2.584,6 € for each patient of group C. Each patient of group B was about 1.9 times more expensive than an asymptomatic one (group A) and about 1.36 times more expensive than one operated in emergency (group C). The conversion rate of the groups was not statistically significant, whereas the length of hospital stays was: patients in group B had longer hospital stays compared to patients in groups A and C. CONCLUSION Early laparoscopic cholecystectomy for complicated cholelithiasis is the cheapest treatment considering the costs of health care, causing lower social costs related to absence from work and an improved perception of the quality of life.

Abstract
Background. Radiofrequency ablation (RFA) has been recently advocated as an effective technique for the treatment of symptomatic benign thyroid nodules. It is not known to what extent it may affect any subsequent thyroid surgery and/or histological diagnosis. Materials and Methods. RFA was performed on 64 symptomatic Thy2 nodules (benign nodules) and 6 symptomatic Thy3 nodules (follicular lesions/follicular neoplasms). Two Thy3 nodules regrew after the procedure, and these patients accepted to undergo a total thyroidectomy. Here we present how RFA has affected the operation and the final pathological features of the surgically removed nodules. Results and Conclusions. RFA is effective for the treatment of Thy2 nodules, but it should not be recommended as first-line therapy for the treatment of Thy3 nodules (irrespective of their mutational status), as it delays surgery in case of malignancy. Moreover, it is unknown whether RFA might promote residual tumor progression or neoplastic progression of Thy3 lesions. Nevertheless, here we show for the first time that one session of RFA does not affect subsequent thyroid surgery and/or histological diagnosis.

Abstract
BACKGROUND BRAF(V600E) mutation, which represents the most frequent genetic mutation in papillary thyroid carcinoma (PTC), is widely considered to have an adverse outcome on PTC outcome, however its real predictive value is not still well stated. The aim of the present study was to evaluate if BRAF(V600E) mutation could be useful to identify within patients with intrathyroid ultrasound-N0 PTC those who require more aggressive treatment, by central neck node dissection (CLND) or subsequent postoperative (131)I treatment. METHODS Among the whole series of 931 consecutive PTC patients operated on at 2nd Clinical Surgery of University of Padova and at General Surgery Department of University of Trieste during a period from January 2007 to December 2012, we selected 226 patients with an intrathyroid tumor and no metastases (preoperative staging T1-T2, N0, M0). BRAF(V600E) mutation was evaluated by PCR-single-strand conformation polymorphism analysis and direct genomic sequencing. We analyzed the correlation between the presence/absence of the BRAF(V600E) mutation in the fine-needle aspiration (FNA) and the clinical-pathological features: age, gender, extension of surgery, node dissection, rate of cervical lymph node involvement, tumor size, TNM stage, variant of histotype, mono/plurifocality, association with lymphocitary chronic thyroiditis, radioactive iodine ablation doses, and outcome. RESULTS The BRAF(V600E) mutation was present in 104 of 226 PTC patients (47.8%). BRAF(V600E) mutation correlated with multifocality, more aggressive variants, infiltration of the tumoral capsule, and greater tumor's diameter. BRAF(V600E) mutation was the only poor prognostic factor in these patients. DISCUSSION In our series, BRAF(V600E) mutation demonstrated to be an adverse prognostic factor indicating aggressiveness of disease and it could be useful in the management of low-risk PTC patients, as supplementary prognostic factor to assess the preoperative risk stratification with the aim to avoid unnecessary central neck node dissection (BRAF pos.) or to perform complementary (131)I-therapy (BFAF neg.).

Abstract
Objective. Benign thyroid nodules are a common occurrence whose only remedy, in case of symptoms, has always been surgery until the advent of new techniques, such as radiofrequency ablation (RFA). This study aimed at evaluating RFA efficacy, tolerability, and costs and comparing them to hemithyroidectomy for the treatment of benign thyroid nodules. Design and Methods. 37 patients who underwent RFA were retrospectively compared to 74 patients surgically treated, either in a standard inpatient or in a short-stay surgical regimen. Efficacy, tolerability, and costs were compared. The contribution of final pathology was also taken into account. Results. RFA reduced nodular volume by 70% after 12 months and it was an effective method for treating nodule-related clinical problems, but it was not as effective as surgery for the treatment of hot nodules. RFA and surgery were both safe, although RFA had less complications and pain was rare. RFA costed €1,661.50, surgery costed €4,556.30, and short-stay surgery costed €4,139.40 per patient. RFA, however, did not allow for any pathologic analysis of the nodules, which, in 6 patients who had undergone surgery (8%), revealed that the nodules harboured malignant cells. Conclusions. RFA might transform our approach to benign thyroid nodules.

Abstract
AIM Over the past decade, several centralization programs for major pancreatic surgery have been implemented in hospitals with high procedural volumes. Although the impact of this process was altogether positive, also possible negative effects have been evidenced, above all the lack of comprehensive coverage and access to specialized centers. In order to solve these problems, it was proposed the utilization of an outcome-based and not volume-based center selection. For this purpose the choice of an appropriate outcome assessment system is crucial. MATERIAL OF STUDY We retrospectively reviewed 74 patients undergoing pancreatoduodenectomy. The outcomes were evaluated utilizing the Accordion Severity Classification of Postoperative Complications. RESULTS The morbidity of 58 % and the mortality of 4 % were comparable with the ones reported in large series utilizing the same classification system. CONCLUSIONS The Accordion system is an effective method of quality control for pancreatic surgery both in high- and low-volume hospitals.

[PMID: 22737167 PMCID: PMC3379162 DOI: 10.1155/2012/539542] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2011] [Revised: 03/21/2012] [Accepted: 04/16/2012] [Indexed: 12/27/2022] Open
Abstract
Introduction. Elderly patients with primary hyperparathyroidism (pHPT) are often not referred to surgery because of their associated comorbidities that may increase surgical risk. The aim of the study was to review indications and results of minimally invasive approach parathyroidectomy in elderly patients to evaluate its impact on outcome. Materials and Methods. All patients of 70 years of age or older undergoing minimally approach parathyroidectomy at our Department from May 2005 to May 2011 were reviewed. Data collected included patients demographic information, biochemical pathology, time elapsed from pHPT diagnosis to surgical intervention, operative findings, complications, and results of postoperative biochemical studies. Results and Discussion. 37 patients were analysed. The average length of stay was 2.8 days. 11 patients were discharged within 24 hours after their operation. Morbidity included 6 transient symptomatic postoperative hypocalcemias while one patient developed a transient laryngeal nerve palsy. Time elapsed from pHPT diagnosis to first surgical visit evidences that the elderly patients were referred after their disease had progressed. Conclusions. Our data show that minimally invasive approach to parathyroid surgery seems to be safe and curative also in elderly patients with few associated risks because of combination of modern preoperative imaging, advances in surgical technique, and advances in anesthesia care.

Abstract
AIM The objective of this study is to determine the optimal surgical approach for patients undergoing thyroid operation for indeterminate follicular lesions diagnosed by cytology and to evaluate the long-term outcome of patients treated by hemi or total thyroidectomy for these lesions. MATERIAL OF STUDY From January 2000 to January 2010, 98 patients having a solitary thyroid nodule with a cytological diagnosis of "indeterminate follicular lesion" were selected retrospectively. RESULTS There were 81 women and 17 men with a mean age of 56 years (range: 28-83). Hemithyroidectomy (HT) was performed in 57 patients (58%) and a Total thyroidectomy (TT) in 41 (42%). Postoperative morbidity was 3.50% in patients who underwent HT and 9.75% in those who underwent TT At the histological analysis 16 (16.32%) patients had a malignant lesion. DISCUSSION HT was considered adequate treatment for 51 patients (89.48%) while in 6 patients (10.52%) has been necessary a completion thyroidectomy. Total thyroidectomy was not associated with clinically significant additive morbidity No permanent hypoparathyroidism and no definitive recurrent nerve palsies were observed in either group. Postoperative thyroid hormone replacement was required in 40.35% of lobectomy patients. Overall, in the indeterminate follicular lesions patient population, 57 hemithyroidectomies were performed and no further operation was required in about 90% of patients. CONCLUSIONS Considering the high rate in which HT represents the adequate treatment, and the low rate of re-operation morbidity, HT seems to be the preferable initial surgical approach for indeterminate follicular lesions. Long-term ultrasonographic follow-up seems advisable.

Abstract
BACKGROUND Aim of this study is to analyze our preliminary results from minimally invasive video-assisted parathyroidectomy (MIVAP) and to evaluate the clinical impact of intraoperative measurements of intact parathyroid hormone (PTHIO). PATIENTS AND METHODS MIVAP by an anterior approach was proposed for patients with sporadic primary hyperparathyroidism pHPT and one unequivocally enlarged parathyroid gland on preoperative ultrasound and 99mTc-SestaMIBI scintigraphy. We used an operative technique first described by Miccoli in 1997, without carbon dioxide insufflation. Quick parathyroid hormone immunochemiluminometric assay (qPTHa) was performed intraoperatively during all surgical procedures. Age, operative times, pathologic findings, postoperative pain, calcemia, length of hospital stay, cosmetic results, and complications were retrospectively analyzed. RESULTS From October 2006 to December 2009, MIVAP was proposed for 28 of 40 (70%). Mean operative time was 65 minutes. Postoperative complications included 4 (12.9%) transient hypocalcemia and one (3.22%) transient nerve palsy with complete recovery. No definitive laryngeal nerve palsies, no definitive hypocalcemias, no persistent pHPT and no recurrent pHPT were observed. The cosmetic result was excellent in all cases. CONCLUSIONS Our preliminary results demonstrate that MIVAP for localized single-gland adenoma, after adequate training, seems to be feasible with significant advantages, especially in terms of cosmetic results, postoperative pain, and postoperative recovery, if performed by dedicated team, with a sufficient and specific activity volume.

Abstract
BACKGROUND The aim of this study is to analyze our preliminary results from minimally invasive video-assisted parathyroidectomy (MIVAP) and demonstrate the feasibility of MIVAP also in non-referral centers. MATERIAL AND METHODS During a period from June 2005 to January 2008, in the General Surgery Department of University of Trieste, we operated on 39 patients with primary hyperparathyroidism (pHPT). MIVAP by an anterior approach was proposed for 23 (59%) patients with sporadic pHPT and one unequivocally enlarged parathyroid gland on pre-operative ultrasound and 99mTc-SestaMIBI scintigraphy without associated goiter and without previous neck surgery. Intra-operatively, a quick parathyroid assay was used during the last 11 surgical procedures. All patients underwent pre-operative and post-operative investigations of calcemia, phoshoremia and PTH levels and vocal cord function. Age, operative times, pathologic findings, post-operative pain, calcemia, length of hospital stay, cosmetic results, and complications were retrospectively analyzed. RESULTS MIVAP was successfully accomplished in 22 cases. Conversion to standard cervicotomy was required in one patient (4.34%). Mean operative time was 67 min. Post-operative complications included 1 (4.34%) transient hypocalcemia. No laryngeal nerve palsies, no definitive hypocalcemias, no persistent pHPT and no recurrent pHPT were observed. The cosmetic result was excellent in all cases. CONCLUSIONS Our preliminary results demonstrate that MIVAP for localized single-gland adenoma, after adequate training, seems to be feasible with significant advantages, especially in terms of cosmetic results, post-operative pain, and post-operative recovery even in a General Surgery Department, if performed by a dedicated team, with a sufficient and specific activity volume.

Abstract
UNLABELLED This article reports a case of unusual pancreatic trauma, underestimated initially and treated surgically at a later stage. A 26-year-old man presented with an abdominal trauma sustained during a soccer game. The patient arrived 24 hours after the trauma with abdominal pain associated to vomiting and intestinal occlusion. Laboratory tests revealed elevated serum amylase levels. An abdominal computed tomography (CT) scan showed a pancreatic parenchymal dishomogeneity at the passage between body and tail, highly suspicious for pancreatic full thickness laceration. Magnetic resonance pancreatography (MRP) demonstrated possible duct involvement. The patient was urgently submitted to distal pancreatectomy with splenectomy. This case demonstrates a rare mechanism of injury and the potential importance of serial CT scans in the diagnosis, grading, and management of isolated pancreatic injury. KEYWORDS pancreatic injury; blunt abdominal trauma; pancreas; duct disruption.

Abstract
BACKGROUND The aim of this study is to demonstrate the functional capacity of thyroid autografts after total thyroidectomy in a rat model. MATERIALS AND METHODS 60 rats were divided into 6 groups of 10 rats each. Thyroid gland was cut into 0.5 mm pieces and was inserted intramuscularly into the left rectus abdominis muscle at different time intervals following total thyroidectomy. The animals were observed for 30 days. Blood samples were collected weekly for TSH, FT3 and FT4 measurements. This study was conducted in strict accordance with the provisions of the law concerning test procedures on animals, as per Legislative Decree n.116/92. RESULTS Autologous transplantations were successful in 70% of the cases. Histopathological findings showed normal thyroid architecture. It was observed that thyroid function recovered was more rapidly if the implants were performed immediately after thyroidectomy than in implants performed at a later time. These results could be due to the thyroid tissue preserving procedure used which may have led to reduce the restored thyroid function in the groups of animals where the implantation was not immediate. CONCLUSIONS Ectopically transplanted thyroid tissue is able to survive and recover its function completely if maintained vital in an adequate preserving medium.

Abstract
INTRODUCTION Idiopathic mesenteric venous thrombosis is a rare entity. An early diagnosis and thrombolytic and anticoagulant therapy are very important. PATIENT AND METHODS We report a case of a patient, without any specific known risk factor, with small intestinal ischemia secondary to superior mesenteric vein thrombosis (SMVT). RESULTS In our case, only a computed tomography (CT) abdominal scan permitted the diagnosis of SMVT. The patient was successfully treated by resection of the infarcted bowel with primary anastomosis and immediate postoperative anticoagulation. CONCLUSIONS Diagnosis of intestinal ischemia from mesenteric venous thrombosis (MVT) is often delayed because the symptoms are nonspecific. Moreover, when there is not any known predisposing factor, the diagnosis may become even more difficult with significant morbidity and mortality. CT abdominal scan done early in case of nonspecific abdominal pain, since the patients had a previous history of venous thrombosis, may not require a surgical treatment of MVT.

Abstract
The aim of this retrospective study is to evaluate the immediate and late outcomes of the surgical and conservative treatment of adhesive small bowel obstruction. A series of 163 consecutive patients affected by adhesive occlusion were analysed. 63 patients were submitted to emergency surgery and 100 to conservative treatment; 15 of these ones were operated on because they did not improve or deteriorated. The in-hospital mortality and morbidity, the length of the ileus, the time required for the operation, the length of the recovery, and the late results after a median follow-up of 3.6 years (range: 1-6 years) are reported. The overall mortality was 3.26% and there was no significant difference (p = 0.764) between the treatment modalities. The patients submitted to conservative therapy had a lower morbidity, shorter length of the ileus and shorter hospital stay and a better outcome at follow-up. In the surgical group, the patients submitted to emergency surgery had a lower mortality, a shorter ileus and shorter hospital stay than the patients submitted to delayed surgery. Conservative treatment of adhesive occlusions should be opted for when the indications are correct (no intestinal ischaemia, no occlusion by a bridle). In doubtful cases, the patient should be submitted to emergency surgery to avoid the risks of surgical delay.

Parathyroid hormone levels 4 hours after surgery do not accurately predict post-thyroidectomy hypocalcemia. Surgery 2006; 140:1016-23; discussion 1023-5.

Abstract
BACKGROUND We evaluated the reliability of intact parathyroid hormone (iPTH) levels 4 hours after thyroidectomy (4h-iPTH) as a predictor of hypocalcemia in a large series of patients. METHODS A prospective experimental design involving 523 consecutive patients between September 1, 2004, and June 30, 2005, was employed. The specificity, sensitivity, and overall accuracy of 4h-iPTH in predicting post-thyroidectomy hypocalcemia and symptoms were determined. RESULTS A total of 199 patients developed hypocalcemia (serum calcium concentrations <8.0 mg/dl). Five patients still were receiving vitamin D/oral calcium at 6 months after the operation. Seventy-three patients experienced mild symptoms. The 4h-iPTH levels were reduced in hypocalcemic patients (28.8 +/- 15.3 vs 11.2 +/- 11.6 pg/ml) (P < .001). The 4h-iPTH levels were within the normal range (10 to 65 pg/ml) in 360 patients (290 normocalcemic) and subnormal in 163 patients (129 hypocalcemic, of whom 62 were symptomatic). The accuracy of 4h-iPTH levels <10 pg/ml in predicting post-thyroidectomy hypocalcemia and symptoms was 80.1% and 78.6%, respectively. False-negative results were observed in 70 hypocalcemic patients (13.4%), 11 of whom were symptomatic (2.1%). CONCLUSIONS Subnormal 4h-iPTH levels alone did not accurately predict clinically relevant postoperative hypocalcemia. The optimal cut-off level and its integration with preoperative and postoperative serum calcium concentrations should be reconsidered.
