    Premessa: Il tumore del seno è nei paesi occidentali al primo posto per frequenza nelle donne e la sua incidenza è in costante crescita. Grazie soprattutto alla diffusione dello screening mammografico e ad una maggiore consapevolezza del problema, negli ultimi anni è aumentata la diagnosi delle cosiddette lesioni “non palpabili”; parimenti si è assistito ad un importante sviluppo delle metodiche diagnostiche di tipo mininvasivo. Alla tradizionale citologia con ago sottile si sono affiancate infatti varie procedure bioptiche percutanee; tali metodiche microistologiche hanno quasi del tutto sostituito la biopsia chirurgica escissionale e l’esame intra-operatorio al congelatore. Pazienti e metodo: Nella nostra Divisione di Chirurgia Generale, Vascolare e Mininvasiva, dal dicembre 1999 al settembre 2004 abbiamo eseguito, in collaborazione con il servizio di Radiologia, 214 biopsie su guida ecografia utilizzando la vacuum-assisted biopsy (Mammotome® ) con ago 11-Gauge. I risultati ottenuti per ciò che concerne l’accuratezza diagnostica, la quantità e qualità delle informazioni ottenute, il significato delle stesse nella eventuale gestione chirurgica, il discomfort globale per la paziente sono stati analizzati e discussi nel presente lavoro. Risultati: Delle 214 biopsie eseguite con tecnica Mammotome, nell’89,3% dei casi si è trattato di lesioni clinicamente non palpabili, con un diametro medio di 8 mm. L’età media delle pazienti era di 57,6 anni (range 31-88). La positività per patologia maligna è stata di 90 casi (42%). Nei casi di iperplasia duttale atipica e radial scar (6%) è stata effettuata l’exeresi chirurgica della lesione che ha confermato nel 100% dei casi la precedente diagnosi bioptica. Il 19% delle pazienti sottoposte a biopsia Mammotome era stato precedentemente sottoposto ad un prelievo citologico con ago sottile. Confrontando i risultati delle due metodiche, l’attendibilità diagnostica della seconda risulta essere significativamente superiore (p<0,05) come pure il numero di informazioni ottenute (istotipo, invasività, grading, recettori ormonali, etc.); il discomfort legato alla procedura, valutato in termini di dolore (VAS), è risultato inferiore a quello del prelievo con ago sottile (p<0,05). L’unica complicanza della biopsia Mammotome è rappresentata dall’ematoma nella sede del prelievo (8% dei casi). Il numero dei falsi negativi è stato di un caso, dovuto ad un non corretto centraggio del bersaglio. Conclusioni: Allo stato attuale in presenza di una lesione non palpabile della mammella la scelta della metodica diagnostica (agobiopsia o Mammotome) è legata al sospetto radiologico nella prospettiva di un eventuale intervento chirurgico.

    .Background: The aim of this systematic review was to provide comprehensive data on the prevalence of variations of the saphenofemoral junction (SFJ) to prevent misidentification of the SFJ or the incomplete ligation of the tributaries of the great saphenous vein. Methods: A systematic review was conducted using the PubMed, Embase, and Cochrane Library databases through September 14, 2017. To be included in the meta-analysis, a study had to report prevalence data on the morphology of the SFJ or the presence of venous tributaries. Results: A total of 16 studies (7433 legs) were included. The majority of studies were performed during varicose vein surgery (74.14%), with fewer studies by means of computed tomography venography and cadaveric dissection. The pooled prevalence estimate (PPE) for a duplication of the SFJ with a bifid junction was 9.6% (P ÂĽ .001). The PPE for a duplication of the SFJ with two separate junctions was 1.7%. The PPE for ectasia of the SFJ was 2.3% in type 1, 1.2% in type 2, and 1.7% in type 3. The distribution of the PPE for the number of venous SFJ tributaries was approximately normal with a slight right skew; a higher rate was observed in the group with four venous tributaries to the SFJ. Conclusions: This analysis found high heterogeneity in the prevalence of SFJ anatomic variants and the number of venous SFJ tributaries. For this reason, it is highly recommended that a preoperative Doppler ultrasound assessment of the SFJ and great saphenous vein be performed. (J Vasc Surg: Venous and Lym Dis 2018;-:1-11.

    [Non palpable lesions of the breast: the Mammotome-biopsy in the preoperative management of breast cancer].

    BACKGROUND: Breast tumour takes first place for frequency in women in Western Countries and is in constant increase. The diagnosis of the so-called non palpable lesions is increased remarkably above all due to the diffusion of mammographic screening and to a greater awareness of the problem. Furthermore it is helped by an important development of mininvasive diagnostic methods: the traditonal cytology with fine needle is supported by various trans-skin bioptic procedures (micro-histological examination). This methods almost always replaces the surgical excisional biopsy and frozen intraoperative examination, still used but reserved for particular cases. PATIENTS AND METHODS: In our Department of General and Mininvasive Surgery, from December 1999 to September 2004, we carried out 214 biopsies, with the collaboration of the radiological Service, under echographic guidance using vacuum--assisted biopsy (Mammotome) with 11-Gauge needle. The results are examined and discussed here in this report with regard to diagnostic accuracy, quantity and quality of information, significant for subsequent surgical management. RESULTS: Of 214 biopsies carried out with Mammotome technique, 89.3% of the cases are clinically non palpable lesions, with a average diameter of 8 mm. The average age of patients was 57.6 years (range 31-88). There are 90 cases of positive malignant pathology (42%). In the atypical ductal iperplasia and radial scar cases (6%) surgical removal of lesion was carried out which confirmed the previous bioptic diagnosis in 100% of cases. The 19% of patients submitted to a Mammotome biopsy was subject previously to cytology with fine needle. Comparing the results of both methods the diagnostic reliability of Mammotome was significantly superior (p < 0.05) as also the amount of information obtained (histotype, invasivity, grading, estrogen receptor, etc.); discomfort linked to the procedure, valued as pain (VAS), resulted inferior to the discomfort of biopsy with fine needle. The only complication of Mammotome biopsy is represented by haematoma in the biopsy site (8% of cases). The number of false negatives was one case due to incorrect targeting. CONCLUSION: In the present situation, the choice of method is conditioned by the degree of radiological suspicion, taking into account the information obtained thereby, in order to ensure the appropriate surgise management. Mammotome biopsy of non palpable lesions of the breast, in our experience, is preferable if suspicion of malignancy is high. In this way a correct preoperative strategy can be prepared. Including the sentinel lymphnode method. Consequently a decision regarding the type of surgery can be taken (generally conservative), as well as making easier the intraoperative localisation of lesion by positioning the metallic clips during biopsy
