Single port endoscopic mastectomy: surgical technique and first case in Mexico.

Las innovaciones técnicas han permitido realizar un sinnúmero de cirugías endoscópicas y laparoscópicas, entre ellas la mastectomía preservadora de piel y pezón por puerto único, que ha sido reportada como bien tolerada, con un excelente resultado cosmético y con el mismo pronóstico oncológico que la cirugía tradicional. Esta técnica, común en Asia, presenta diversos retos técnicos y económicos. Presentamos la primera aproximación en nuestro país sobre este abordaje en una paciente con cáncer de mama. Para realizar esta cirugía es preciso el entrenamiento en mínima invasión y en cirugía mamaria, así como una adecuada selección de las pacientes.Technical innovations and scientific advances have allowed to perform countless endoscopic and laparoscopic surgical procedures. Among these, Single port endoscopic Mastectomy has been reported as well tolerated, with great aesthetic results and the same oncologic prognosis as traditional surgery. This popular approach in Asian countries presents many technical and economic challenges. We present the first endoscopic approach in our country: a female patient with infiltrating ductal carcinoma in the left breast. We understand that to carry out this procedure, adequate patient selection, great minimal invasive and breast surgery skills are necessary.

Secretory breast carcinoma: a report of two cases / Carcinoma secretor de la mama: reporte de dos casos

Secretory breast carcinoma was first described by McDivitt and Stewart in 1966, who reported seven cases of this tumoural strain in children and therefore named it "juvenile carcinoma". However, a couple of decades later, Tavassoli and Norris reported a series of 19 cases and found that most occurred in adults, and therefore they proposed changing its name to "secretory carcinoma." Since then, approximately 100 cases have been reported in the world literature. We present two cases treated with total mastectomy and sentinel node biopsy with excellent outcome. To our knowledge, only a few cases have been reported in Latin American patients

El carcinoma secretor dela mama fue inicialmente descrito por McDivitt y Stewartin en 1966, en su artículo, siete casos de este tipo de tumor se presentaron en niños, por lo tanto, se le asignó el nombre de "carcinoma Juvenil", pero un par de décadas después Tavassoli y Norris encontraron en su serie de 19 casos, que la mayoría eran adultos, y así propusieron cambiar el nombre a Carcinoma secretor. Desde ese momento aproximadamente 100 casos han sido reportados en la literatura. Nosotros presentamos dos casos tratados con mastectomía y ganglio centinela, con excelente pronóstico. Hasta donde sabemos, esta patología se ha reportado escasamente en pacientes latino americanos

[Gallbladder agenesis. Case report]. / Agenesia de la vesícula biliar. Reporte de caso.

BACKGROUND: Gallbladder agenesis is a very rare congenital abnormality of the biliary tract. The diagnosis is made during surgery, because all preoperative studies have failed to identify this malformation. The purpose of this article is to present a case of gallbladder agenesis diagnosed during surgery, its management, and a review of the literature. CLINICAL CASE: The case involves a sixty-two year- old female, referring to repeated biliary colic symptoms. The abdominal ultrasound diagnosed cholelithiasis. It was impossible to identify the gallbladder during surgery. Diagnosis was confirmed by intra-operative cholangiography. DISCUSSION: Preoperative diagnostic workup has failed to recognise patients with gallbladder agenesis. It is currently recommended to abandon the surgery once this diagnosis is suspected and confirm it by a cholangio-magnetic resonance scan in order to avoid a bile duct injury. CONCLUSIONS: Agenesis of the gallbladder is a rare congenital abnormality of the biliary tree. Every surgeon must keep this rare entity in mind when a "difficult dissection" or an anatomic variant is identified during surgery, and make use of an intra-operative cholangiography, mainly to prevent a bile duct injury.
