RESUMO

OBJECTIVES: To assess whether ultrasound elastography (USE) with strain ratio increases diagnostic accuracy of Doppler ultrasound in further characterisation of cytologically Thy3 thyroid nodules. METHODS: In two different university diagnostic centres, 315 patients with indeterminate cytology (Thy3) in thyroid nodules aspirates were prospectively evaluated with Doppler ultrasound and strain ratio USE before surgery. Ultrasonographic features were analysed separately and together as ultrasound score, to assess sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). Receiver operating characteristic (ROC) curves to identify optimal cut-off value of the strain ratio were also provided. Diagnosis on a surgical specimen was considered the standard of reference. RESULTS: Higher strain ratio values were found in malignant nodules, with an optimum strain ratio cut-off of 2.09 at ROC analysis. USE with strain ratio showed 90.6% sensitivity, 93% specificity, 82.8% PPV, 96.4% NPV, while US score yielded a sensitivity of 52.9%, specificity of 84.3%, PPV 55.6% and NPV 82.9%. The diagnostic gain with strain ratio was statistically significant as proved by ROC areas, which was 0.9182 for strain ratio and 0.6864 for US score. CONCLUSIONS: USE with strain ratio should be considered a useful additional tool to colour-Doppler US, since it improves characterisation of thyroid nodules with indeterminate cytology. KEY POINTS: • Strain ratio measurements improve differentiation of thyroid nodules with indeterminate cytology • Elastography with strain ratio is more reliable than ultrasound features and ultrasound score • Strain ratio may help to better select patients with Thy 3 nodules candidate for surgery.

RESUMO

BACKGROUND: Since the great diffusion of laparoscopic treatment of obesity, there is a growing interest concerning the learning process for those surgeons who undertake the bariatric activity. However, papers analyzing the learning curve (LC) for sleeve gastrectomy (SG) are still scarce. This study aims to investigate whether the LC for SG of a novice bariatric surgeon might be positively influenced by the training in a high-volume bariatric center (HVBC). METHODS: Between October 2010 and January 2014, 128 patients underwent SG by the same young surgeon who previously attended a 2-year training in a HVBC. His LC has been divided into three consecutive periods: in the first period (1st-47th SGs) he operated in the HVBC, while in the second (48th-88th SGs) and third period (89th-128th SGs) he moved to a novel department where surgical and ancillary staff were initially not confident with bariatric procedures but progressively owned the proper experience. Preoperative characteristics, operative data, complications and postoperative results of the three periods were compared. RESULTS: Mean follow-up was 1 year. Preoperative patients' characteristics were homogeneous. No significant differences have been registered among the three periods concerning operative data, mortality, intra- and post-operative complications, weight loss outcomes and comorbidities' resolution. Post-operative follow-up rates at 6 and 12 months were 98.4 and 92.1 %, respectively. CONCLUSIONS: Long-lasting fellowship in a HVBC might allow the novel bariatric surgeon to safely and proficiently overcome the LC for SG, even in a new established bariatric setting.

RESUMO

OBJECTIVES: The aims of this study were to determine the presence of endothelial dysfunction by measuring aortic intima-media thickness (aIMT) and carotid intima-media thickness (cIMT) and to evaluate the role of traditional risk factors for premature atherosclerosis in children with inflammatory bowel disease (IBD). METHODS: Thirty-four children with IBD (25 Crohn disease [CD] and 9 ulcerative colitis [UC]; mean age 11.1 years) and 27 healthy subjects matched for sex and age were enrolled. In all of the patients, demographic characteristics and risk factors for atherosclerosis (age, sex, body mass index, blood pressure, dyslipidemia, active and passive smoking, and family history for cardiovascular diseases), CD and UC clinical activity scores, and inflammatory markers were evaluated. aIMT and cIMT were measured by high-resolution B-mode ultrasound. RESULTS: aIMT was significantly higher in patients than in controls (P < 0.0005). No significant differences were found for cIMT, although the carotid thickness was higher in patients with IBD than in healthy subjects. At a univariate analysis, inflammatory markers levels and tobacco smoking exposure were significantly related to higher aIMT values, whereas in a multivariate regression model, the inflammatory status was the only independent variable correlated with high aIMT. CONCLUSIONS: aIMT is an earlier marker of preclinical atherosclerosis than cIMT in young children with active IBD. The inflammatory status and the smoking exposure are significantly correlated with the premature endothelial dysfunction. These data emphasize the importance of controlling the chronic intestinal inflammation and endorsing smoke-free environments for children and adolescents with IBD.

RESUMO

BACKGROUND: Obesity is a major risk factor for several chronic diseases. The BioEnterics(®) Intragastric Balloon (BIB(®)) is used worldwide as a short-term (6 months) treatment in morbid obese patients. However, removal of BIB(®) past 6 months is a common occurrence in clinical practice often as a result of patient factors. The aim of the present Italian multicentre cohort study was to evaluate the safety and efficacy of the BIB(®) left in situ for more than 6 months. MATERIALS AND METHODS: A total of eight Italian centres participated in the study. Participating centres received a standardised questionnaire designed to capture safety and efficacy data. Weight loss data, as well as date, and reason for removal of the BIB(®) after 6 months were recorded. Adverse events, including mortality and complications, operators' subjective technical notes and findings, and difficulties during removal procedure were also collected. RESULTS: Six hundred and eleven patients were included. In the majority of cases, patient extended BIB(®) treatment due to satisfactory weight loss (44 %). At 6 months, all patients achieved a BMI statistically lower than the initial BMI (p < 0.001). There was a non-significant trend towards greater BMIL % in patients who underwent removal up to 15 months versus the results achieved up to 6 months. No major complications were recorded. CONCLUSION: Extending the duration of BIB(®) use up to 14 months safely maintains weight loss and satiety with greater results than that up to 6 months, without complications.

RESUMO

BACKGROUND: The rising interest towards minimally invasive surgery has led to the introduction of laparo-endoscopic single site (LESS) surgery as the natural evolution of conventional multiport laparoscopy. However, this new surgical approach is hampered with peculiar technical difficulties. The SPIDER surgical system has been developed in the attempt to overcome some of these challenges. Our study aimed to compare standard laparoscopy and SPIDER technical performance on a surgical simulator, using standardized tasks from the Fundamentals of Laparoscopic Surgery (FLS). METHODS: Twenty participants were divided into two groups based on their surgical laparoscopic experience: 10 PGY1 residents were included in the inexperienced group and 10 laparoscopists in the experienced group. Participants performed the FLS pegboard transfers task and pattern cutting task on a laparoscopic box trainer. Objective task scores and subjective questionnaire rating scales were used to compare conventional laparoscopy and SPIDER surgical system. RESULTS: Both groups performed significantly better in the FLS scores on the standard laparoscopic simulator compared to the SPIDER. Inexperienced group: Task 1 scores (median 252.5 vs. 228.5; p = 0.007); Task 2 scores (median 270.5 vs. 219.0; p = 0.005). Experienced group: Task 1 scores (median 411.5 vs. 309.5; p = 0.005); Task 2 scores (median 418.0 vs. 331.5; p = 0.007). Same aspects were highlighted for the subjective evaluations, except for the inexperienced surgeons who found both devices equivalent in terms of ease of use only in the peg transfer task. CONCLUSIONS: Even though the SPIDER is an innovative and promising device, our study proved that it is more challenging than conventional laparoscopy in a population with different degrees of surgical experience. We presume that a possible way to overcome such challenges could be the development of tailored training programs through simulation methods. This may represent an effective way to deliver training, achieve mastery and skills and prepare surgeons for their future clinical experience.

RESUMO

BACKGROUND AND STUDY AIMS: Second-generation colon capsule endoscopy (CCE-2) may overcome the invasiveness of colonoscopy in the evaluation of mucosal inflammation, especially in pediatric ulcerative colitis. The aim of this pilot study was to determine the diagnostic accuracy of CCE-2 in evaluating disease activity, using colonoscopy as a gold standard. Disease extent, tolerability, interobserver agreement, and safety were also evaluated. METHODS: A total of 30 consecutive pediatric patients with ulcerative colitis were prospectively enrolled (mean age 14.1 ±â€Š3.2 years). Patients underwent CCE-2 followed by colonoscopy in the late afternoon or the following day. The blinded procedures were performed, and the diagnostic accuracy of CCE-2 to assess disease activity was determined using a modified Matts score, which classified patients as either normal (Matts score ≤ 6) or with active inflammation (Matts score > 6). Interobserver agreement was assessed using the kappa statistic. RESULTS: One patient was excluded from the analysis because they were unable to swallow the capsule, leaving 29 patients available for analysis. The sensitivity of CCE-2 for disease activity was 96 % (95 % confidence interval [CI] 79 - 99) and specificity was 100 % (95 %CI 61 - 100). The positive and negative predictive values of CCE-2 were 100 % (95 %CI 85 - 100) and 85 % (95 %CI 49 - 97), respectively. No serious adverse events were reported. CCE-2 had a higher overall tolerability than colonoscopy (P < 0.05). Interobserver agreement was excellent in all cases (κ > 0.86). CONCLUSIONS: Using a modified Matts score, CCE-2 was accurate in evaluating significant mucosal inflammation in children with ulcerative colitis. TRIAL REGISTRATION: ClinicalTrials.gov -- NCT01740349.

RESUMO

OBJECTIVE: Evaluation of the diagnostic efficacy and interobserver agreement of Q-elastography in the differentiation of benign from malignant thyroid nodules. METHODS: A total of 344 thyroid nodules in 288 patients were examined with grey-scale and colour Doppler ultrasound (CDUS) and Q-elastography by two independent operators. Nodules with hypoechogenicity, poorly defined margins, microcalcifications, and intralesional vascularity were classified as suspicious. Diagnostic performances of CDUS features and Q-elastography for predicting thyroid malignancy were estimated using ROC analysis. Cytology or histopathology was the reference standard. Interobserver agreement in the evaluation of CDUS and Q-elastography was assessed using Cohen's k-statistic. RESULTS: Q-elastography showed excellent diagnostic performance for the prediction of thyroid malignancy, with sensitivity of 93 % and specificity of 92 % for operator 1 (best cutoff at 2.02), and sensitivity of 84 % and specificity of 79 % for operator 2 (best cutoff at 1.86). Performance of Q-elastography was superior to that of CDUS. Reproducibility of the findings was excellent for both Q-elastography and CDUS features as assessed with Cohen's k, which was highest for strain ratio measurements (0.95) and lowest for the echogenicity score (0.83). CONCLUSIONS: Q-elastography showed excellent performance. It is a valid and reproducible diagnostic method as well as a promising tool for identifying suspicious solid thyroid nodules needing cytological assessment and surgery. KEY POINTS: • Elastography is an additional tool for optimal characterisation of malignant thyroid nodules. • The use of semiquantitative elastographic evaluation increases the diagnostic performance, • The interobserver agreement of quantitative elastography can be considered to be good.

RESUMO

BACKGROUND: Construct validity of virtual laparoscopic simulators for basic laparoscopic skills has been proposed; however, it is not yet clear whether the simulators can identify the actual experience of surgeons in more complex procedures such as laparoscopic Roux-en-Y gastric bypass. This study tested the ability of the Lap Mentor simulator to recognize the experience in advanced laparoscopic procedures and to assess its role in the certification of bariatric surgeons. METHODS: Twenty surgeons were divided into two groups according to their experience in laparoscopic and bariatric surgery. The general group included 10 general surgeons performing between 75 and 100 nonbariatric laparoscopic procedures. The bariatric group included 10 bariatric surgeons performing between 50 and 100 laparoscopic bariatric procedures. Participants were tested on the simulator in one basic task (task 1: eye-hand coordination) and in two tasks of the gastric bypass module (task 2: creation of the gastric pouch; task 3: gastrojejunal anastomosis). RESULTS: Comparing the groups, no significant differences were found in task 1. Analyzing the results from the gastric bypass module (bariatric vs. general), in task 2, significant differences (p < 0.05) were found in the median volume of the gastric pouch (21 vs. 48 cm(3)), in the percentage of fundus included in the pouch (8.4 vs. 29.4 %), in the complete dissection at the angle of His (10 vs. 3), and in safety parameters. In task 3, significant differences were found in the size and position of enterotomies. CONCLUSIONS: The Lap Mentor may be proposed as a certification tool for bariatric surgeons because it also recognizes their specific skills in the technical details of the procedure that affect long-term results. Furthermore, the possibility of analyzing the performance in detail can help define areas where the surgeon is lacking. These findings indicate a potential role of the Lap Mentor in tailoring the training to maximize improvement.

RESUMO

BACKGROUND: Distal pancreatectomy (DP) is a surgical procedure performed to remove the pancreatic tail jointly with a variable part of the pancreatic body and including a spleen resection in the case of conventional distal pancreatectomy or not in the spleen-preserving distal pancreatectomy. METHODS: In this article, we describe a standardized operative technique for fully robotic distal pancreatectomy. RESULTS: In the last decade, the use of robotic systems has become increasingly common as an approach for benign and malignant pancreatic disease treatment. Robotic Distal Pancreatectomy (RDP) is an emerging technology for which sufficient data to draw definitive conclusions in surgical oncology are still not available because the follow-up period after surgery is too short (less than 2 years). CONCLUSIONS: RDP is an emerging technology for which sufficient data to draw definitive conclusions of value in surgical oncology are still not available, however this techniques is safe and reproducible by surgeons that possess adequate skills.

RESUMO

BACKGROUND: Deep Vein Thrombosis (DVT) is an important cause of morbidity and is the first cause of maternal death after delivery in Western Nations. The risk of venous thromboembolism is present throughout the pregnancy and is maximal during postpartum, especially after twin delivery. Many of the signs and symptoms of DVT overlap those of a normal pregnancy causing difficulty for diagnosis. CASE REPORT: We report the case of a 33 year-old woman transferred to our Department one week after caesarean section for twin delivery. She presented with severe abdominal pain, fever, abdominal distension and shortness of breath. She had no personal or family history of thromboembolism. Computerized Tomography Scan revealed right ovarian vein thrombosis, left renal vein thrombosis extending up to the Inferior Vena Cava and pulmonary embolism with bilateral pleural effusion. Caval filter was positioned and anticoagulation therapy associated with antibiotics was instituted. Pancreatitis showed up two days after and was promptly treated. Three months after discharge the caval filter was removed and oral anticoagulation was stopped. During a 12-months follow-up, she remained stable and symptom free. RESULTS: Ovarian vein thrombosis is rare but recognition of signs and symptoms is fundamental to start adequate therapy and avoid potential serious sequelae. The risk for maternal postpartum ovarian vein thrombosis is increased by caesarean section delivery of twins. Such patients should be closely monitored. We illustrated how an underestimated condition can lead to massive complications.

RESUMO

INTRODUCTION: The goal of non-operative management (NOM) for blunt splenic trauma (BST) is to preserve the spleen. The advantages of NOM for minor splenic trauma have been extensively reported, whereas its value for the more severe splenic injuries is still debated. The aim of this systematic review was to evaluate the available published evidence on NOM in patients with splenic trauma and to compare it with the operative management (OM) in terms of mortality, morbidity and duration of hospital stay. METHODS: For this systematic review we followed the "Preferred Reporting Items for Systematic Reviews and Meta-analyses" statement. A systematic search was performed on PubMed for studies published from January 2000 to December 2011, without language restrictions, which compared NOM vs. OM for splenic trauma injuries and which at least 10 patients with BST. RESULTS: We identified 21 non randomized studies: 1 Clinical Controlled Trial and 20 retrospective cohort studies analyzing a total of 16,940 patients with BST. NOM represents the gold standard treatment for minor splenic trauma and is associated with decreased mortality in severe splenic trauma (4.78% vs. 13.5% in NOM and OM, respectively), according to the literature. Of note, in BST treated operatively, concurrent injuries accounted for the higher mortality. In addition, it was not possible to determine post-treatment morbidity in major splenic trauma. The definition of hemodynamic stability varied greatly in the literature depending on the surgeon and the trauma team, representing a further bias. Moreover, data on the remaining analyzed outcomes (hospital stay, number of blood transfusions, abdominal abscesses, overwhelming post-splenectomy infection) were not reported in all included studies or were not comparable, precluding the possibility to perform a meaningful cumulative analysis and comparison. CONCLUSIONS: NOM of BST, preserving the spleen, is the treatment of choice for the American Association for the Surgery of Trauma grades I and II. Conclusions are more difficult to outline for higher grades of splenic injury, because of the substantial heterogeneity of expertise among different hospitals, and potentially inappropriate comparison groups.

RESUMO

BACKGROUND: Bariatric surgery is an effective treatment to obtain weight loss in severely obese patients. The feasibility and safety of bariatric robotic surgery is the topic of this review. METHODS: A search was performed on PubMed, Cochrane Central Register of Controlled Trials, BioMed Central, and Web of Science. RESULTS: Twenty-two studies were included. Anastomotic leak rate was 8.51% in biliopancreatic diversion. 30-day reoperation rate was 1.14% in Roux-en-Y gastric bypass and 1.16% in sleeve gastrectomy. Major complication rate in Roux-en-Y gastric bypass resulted higher than in sleeve gastrectomy ( 4,26% vs. 1,2%). The mean hospital stay was longer in Roux-en-Y gastric bypass (range 2.6-7.4 days). CONCLUSIONS: The major limitation of our analysis is due to the small number and the low quality of the studies, the small sample size, heterogeneity of the enrolled patients and the lack of data from metabolic and bariatric outcomes. Despite the use of the robot, the majority of these cases are completed with stapled anastomosis. The assumption that robotic surgery is superior in complex cases is not supported by the available present evidence. The major strength of the robotic surgery is strongly facilitating some of the surgical steps (gastro-jejunostomy and jejunojejunostomy anastomosis in the robotic Roux-en-Y gastric bypass or the vertical gastric resection in the robotic sleeve gastrectomy).

RESUMO

PURPOSE: This study was done to compare quantitative elastosonography and ultrasound analysis in the characterisation of thyroid nodules. MATERIALS AND METHODS: From July 2009 to September 2011, 123 patients with 147 thyroid nodules were included in our study. All patients enrolled had to undergo thyroidectomy because of nodular thyroid disease (goitre or nodules). After preliminary examination with conventional ultrasound (US) and colour Doppler US, the patients were examined with elastosonography, using high-level equipment (Toshiba Aplio XG) and quantitative software (Elasto-Q). Each lesion was characterised using an US score (echogenicity, borders, microcalcifications and colour Doppler pattern), and then by elastosonographic strain ratio. Each patient subsequently underwent thyroidectomy. Histological results were used as the gold standard. RESULTS: Histological examination demonstrated 89 benign and 58 malignant lesions. On average, the strain ratio value was 2.84±2.69 (range, 0.05-14.5; p=0.001). Sensitivity and specificity of the US score were about 56% and 72%, respectively, whereas those of the strain ratio were 93% and 89%, using a cut-off of 2 obtained with receiver operating characteristic (ROC) curve analysis. Elastosonography was more accurate than US and colour Doppler US in characterising thyroid nodules (p=0.002). CONCLUSIONS: Quantitative elastosonography is a useful diagnostic tool in the evaluation of thyroid lesions, and can be used to limit fine-needle aspiration cytology and improve the selection of patients for thyroidectomy.

RESUMO

BACKGROUND: The use of pneumatic dilation (PD) is well established in adults with achalasia; however, it is less commonly used in children. OBJECTIVE: To evaluate the efficacy of PD in pediatric achalasia and to define predictive factors for its treatment failure. DESIGN: Single-center, prospective cohort study. SETTING: Academic tertiary referral center. PATIENTS: Twenty-four patients with achalasia were enrolled from January 2004 to November 2009 and were followed for a median of 6 years. INTERVENTION: PD was performed with the patients under general anesthesia. MAIN OUTCOME MEASUREMENTS: Efficacy and safety of PD. Follow-up was performed by using the Eckardt score, barium swallow contrast studies, and esophageal manometry at baseline; 1, 3, and 6 months after dilation; and every year thereafter. A Cox regression model was used to identify independent predictors of failure after the first PD. RESULTS: The PD success rate was 67%. In 8 patients, the first PD failed, but the parents of one patient refused a second PD and requested surgery. Of the 7 patients who underwent repeated treatment, the second PD failed in 3 (43%). Overall, only 3 of the 24 patients underwent surgery (overall success rate after a maximum of 3 PDs was 87%). Multivariate analysis showed that only older age was independently associated with a higher probability of the procedure success (hazard ratio [HR] 0.66; 95% CI, 0.45-0.97). LIMITATIONS: Small sample size, single-center study. CONCLUSIONS: PD is a safe and effective technique in the management of pediatric achalasia. Young age is an independent negative predictive factor for successful clinical outcome.

RESUMO

AIM: Presentation of a personal technique for the treatment of perineal fistulas in outpatients. MATERIAL OF STUDY: 17 patients with complete non-complex linear intersphincteric or trans-sphincteric fistulas were treated with this technique. First we facilitated the cannulation, then we used the same catheters to place the "seton". We had to use a more subtle and smooth, rugged nylon thread, instead of the floss, due to the difference between the large size of the silk thread and the small lumen of the cannula. RESULTS: The elastic traction has determined not only a valid mean of capillary drainage, but also a rapid passage through the tissues without any functional impairment, in times ranging from 2 to 4 weeks. DISCUSSION: The traditional surgery is burdened by a significant number of relapses . This is due to the anatomical characteristics of the anal canal, to the difficulty to ensure the integrity of the sphincteric structures and to the position of the fistula. It's essential to identify the whole extension of the fistula to avoid it's partial removal and the persistence of granulation tissue therefore. With our technique, we got a good drainage of the fistula, avoiding to leave any residues or to create false paths causing relapses as may happen with the explorers. CONCLUSIONS: The discomfort suffered by patients was minimal and the results achieved led us to support a greater diffusion of this technique in outpatients.

RESUMO

AIM: The objective was to compare Carotid Endarterectomy (CEA) with Carotid Artery Stenting (CAS) in terms of efficacy and safety in patients with symptomatic and asymptomatic extracranial carotid stenosis. MATERIALS: This study enrolled 285 patients with symptomatic and asymptomatic carotid stenosis that underwent either to CAS or CEA. The primary end-points were death, stroke and myocardial infarction. The secondary end-points were restenosis and nerve injury. The Data emerged from the follow-up at 1,3,6,12,24 months that provided for clinical and EcocolorDoppler monitoring. A separate analyse was performed evaluating the prediction of the Ultrasonographic appearance of the atheroma on the symptomatic nature of the lesion. RESULTS: The percentage of neurological symptomatology in the periprocedural period was higher in CAS than in CEA group (9% vs 3%). We didn't report any case of periprocedural death. The results from the follow-up are: myocardial infarction 5% CAS vs 7% CEA; stroke 5% CAS vs 4% CEA; restenosis 3% CAS vs 6% CEA; nerve injury 0% CAS vs 1% CEA; mortality 0% CAS vs 1% CEA. DISCUSSION: CEA is the gold standard for treatment of significant carotid stenosis, although endovascular technique is emerging as a less invasive alternative. CAS has presented a less frequence of myocardial infarction, nerve injury and long-term mortality, but it showed an higher percentage of neurological events both in short and long-term. This last aspect is correlated with the plaque structure. Ultrasonographic study of the atheroma has become a defining moment in the choice of the therapeutic strategy.

RESUMO

Sarcoma of the breast is a rare condition, with one possible meaning of relapse ad metastastasize, and behaves biologically as a stromal tumor. Surgery is the first choise and mastectomy is the best procedure adopted in these tumors. The aim of our study was to assess diagnostic and treatment options for PT, based on a review of the literature and our experience with a case of breast sarcoma arising from a phyllodes tumor.

RESUMO

In anterior resection of rectum, the section level of inferior mesenteric artery is still subject of controversy between the advocates of high and low tie. The low tie is the division and ligation to the branching of the left colic artery and the high tie is the division and ligation at its origin at the aorta. We intend to assess current scientific evidence in literature and to establish the differences comparing technique, anatomy and physiology. The aim of this protocol is to achieve a meta-analysis that tests safety and feasibility of the two procedures with several types of outcome measures.

RESUMO

AIM: The study of the Mondor's syndrome as a possible complication of gigantomastia. MATERIAL AND METHOD: A 49 year old woman, with gigantomastia, came to our observation for the presence of a large superficial vein of the left breast affected by thrombophlebitis, compatible with Mondor's syndrome. RESULTS: A "Thorek" breast reduction was performed; the patient was discharged on the second postoperative day and the follow up was smooth and fee from any complications. DISCUSSION: In the case we observed, gigantomastia had a clear role in the pathogenesis of the Mondor's disease; in fact, the excessive weight of the breasts caused stretching of the mammary dorsal vein evolving in phlebitis. In literature, among the causes related to Mondor's disease the pendulous breast is described, probably with the same dynamic we have seen in this patient, but has never reported, so obviously, the correlation between the two events. It's considered as good practice in the pre-operative evaluation, to make differential diagnosis with any cancer, that, in a certain percentage, is associated with Mondor's syndrome, and once established the causes of the pathology, it is imperative to eliminate them to prevent any relapses. CONCLUSION: Among the various causes recognized as predisposing to Mondor's syndrome, there has never been described gigantomastia so far. The observation and treatment of a patient in whom the gigantomastia certainly led to the onset of Mondor's disease, has led us to consider this as one of the possible complications of gigantomastia, providing an additional cue to the treatment of this condition even at an early stage.

RESUMO

The Authors refer their experience of a patient operated for adenoma of the inferior parathyroid of left lobe associated to a limphoadenopathy fom HD. Diagnostic and therapeutical approach are described. The literature of these last decades reports a single case with similar characteristics, but not with the same association. Numerous neoplasias associated more frequently with parathyroid adenoma are mentioned and the probable causes of this association. Although the associations with other affections of the hemolymphopoietic system are relatively frequent, the causes of the rarity of the association between parathiroid adenoma and HD remain unknown.
