Duodenal stenosis surgical treatment in Crohn's disease.

We present the case of a 34-year-old man with daily vomiting and 20% weight loss in a year. A gastroduodenoscopy was performed, noticing 2nd and 3rd duodenal portion dilatation and inflammatory involvement of the 3rd and 4th portion, causing luminal stenosis. These findings are the same than in the magnetic resonance . The biopsy proves the histological diagnosis of Crohn's disease. At the beginning the patient was treated with Prednisone, Adalimumab and Ustekinumab. After 9 months, surgery was decided because the disease was refractory to treatment and there was corticosteroid dependence. A partial resection of 3rd and 4th portion of the duodenum and the first loop of jejunum was performed, with duodenojejunal anastomosis. The patient presents good postoperative evolution and after 1 year he remained asymptomatic under treatment with Ustekinumab.

Tratamiento quirúrgico de la fibromatosis agresiva en relación con cesárea previa / Surgical treatment of aggressive fibromatosis in relation to previous cesarean section

Introducción. Los tumores desmoides son lesiones de los tejidos blandos, histológicamente benignas, poco frecuentes y con gran agresividad local y carencia de potencial metastásico. Se relacionan estrechamente con antecedentes traumáticos o quirúrgicos, como la cesárea, y su tratamiento generalmente es quirúrgico. Métodos. Presentamos una serie de tres pacientes intervenidas en nuestro centro durante el año 2020. Se revisan sus antecedentes y se describe su tratamiento. Resultados. En todas nuestras pacientes se encontró algún antecedente quirúrgico, dos cesáreas y una resección de un disgerminoma. El tratamiento empleado fue la resección quirúrgica con márgenes libres y reparación del defecto mediante malla. Conclusiones. El tumor desmoide es una patología poco frecuente, su diagnóstico se realiza mediante exámenes imagenológicos y se confirma con el estudio histológico; es importante hacer el diagnóstico diferencial con el sarcoma. La cirugía radical sigue siendo el tratamiento de elección, aunque algunos autores proponen el tratamiento conservador.

Introduction. Desmoid tumors are soft tissue lesions, histologically benign, rare and with great local aggressiveness and lack of metastatic potential. They are closely related to traumatic or surgical history such as caesarean section. Their treatment is generally surgical. Methods. We present a case series of three patients operated on in our center during the year 2020. Their history is reviewed and their type of treatment is presented. Results. In all our patients, surgical history was found (two caesarean sections and one resection of a dysgerminoma). The treatment used was surgical resection with free margins and mesh repair of the defect. Conclusions. Desmoid tumor is a rare pathology; its diagnosis is made by imaging studies, and confirmed by histology. It is important to make a differential diagnosis with sarcoma. Radical surgery remains the treatment of choice, although some authors propose conservative treatment.

Contralateral breast cancer and tumor recurrence in BRCA1/2 carriers and non-carriers at a high risk of hereditary breast cancer after bilateral mastectomy. / Cáncer de mama contralateral y recurrencia en portadoras BRCA1/2 y no portadoras con alto riesgo de cáncer de mama hereditario tras mastectomía bilateral.

INTRODUCTION: Contralateral prophylactic mastectomy (CPM) has been reported to reduce risk of contralateral breast cancer (CBC) by at least 90%.In addition, BRCA carriers presents higher risk of ipsilateral recurrence and a second primary tumor. The aim is to evaluate risk of CBC and recurrence and to analyze predictive factors in BRCA1/2 mutation carriers and non-carriers at high-risk of hereditary breast cancer patients. METHODS: Retrospective observational study. 46 patients underwent bilateral mastectomy during 2004-2018. RESULTS: Cohort comprised 9 patients BRCA1,12 BRCA2 and 25 at high-risk without mutation. Median follow-up 79 months. 16 patients recently diagnosed and 30 previously treated by breast cancer whom underwent CPM at second time (because of later detection of BRCA mutation in 10 cases). The external lateral incision was most frequent surgical technique. In all patients immediate reconstruction was performed. In CPM pieces, 4 in situ carcinoma, 3 invasive and 1 atypical hyperplasia were found. The incidence of occult contralateral cancer was 15.2%. Recurrence was observed in 5 patients a media of 21.2 months after surgery. FSD was 83.74 months and OS 84.33 months. Regression models identified BRCA1/2 mutation and high risk without mutation as significant occult tumor predictive factors while tumor size≥2cm was predictive of recurrence. CONCLUSIONS: In our series we found a10.8% recurrence despite CPM and 7 patients (15.2%) would have developed a CBC in subsequent years.
