A 75-year-old woman was admitted with complaints of progressive portprandial abdominal pain and weight loss. A bruit was audible in the epigastrium. Angiogram showed narrowing of the lower abdominal aorta with complete occlusion of the celiac, the superior and inferior mesenteric arteries. A 6mm Gore-Tex graft was first anastomosed from the supraceliac abdominal aorta to the superior mesenteric artery. A saphenous vein graft was then inserted proximally to the Gore-Tex graft and distally to the celiac artery. The postoperative course was uneventful. During two years of observation symptoms have disappeared and patient returned to a normal weight.

Treatment of perianal and vulvar extramammary Paget disease (EMPD), rare intraepithelial malignancies, is often challenging because of its potential to spread into the anal canal. However, there is still no consensus regarding the optimal resection margin within the anal canal. Between 2004 and 2014, six patients (three with perianal EMPD and three with vulvar EMPD) in which the spread of Paget cells into the anal canal was highly suspected were referred to our department. To evaluate the disease extent within the anal canal, preoperative mapping biopsy of the anal canal was performed in five out of six patients. Two patients were positive for Paget cells within the anal canal (one at the dentate line and the other at 0.5 cm above the dentate line), whereas in three patients, Paget cell were present only in the skin of the anal verge. Using 1 cm margin within the anal canal from the positive biopsy sites, we performed anal-preserving wide local excision (WLE), and negative resection margins within the anal canal were confirmed in all five patients. The remaining one patient with perianal EMPD did not undergo mapping biopsy of the anal canal because preoperative colonoscopy revealed that the Paget cells had spread into the lower rectum. Therefore, WLE with abdominoperineal resection was performed. During the median follow-up period of 37.3 months, no local recurrence was observed in all patients. Our small case series suggest the usefulness of mapping biopsy of the anal canal for the treatment of perianal and vulvar EMPD.

Onco-testicular sperm extraction is used to preserve fertility in patients with bilateral testicular tumors and azoospermia. We report the case of a testicular tumor in the solitary testis of a patient who had previously undergone successful contralateral orchiectomy and whose sperm was preserved by onco-testicular sperm extraction. A 35-year-old patient presented with swelling of his right scrotum that had lasted for 1 month. His medical history included a contralateral orchiectomy during childhood. Ultrasonography revealed a mosaic echoic area in his scrotum, suggesting a testicular tumor. The lesion was palpated within the normal testicular tissue along its edge and semen analysis showed azoospermia. Radical inguinal orchiectomy and onco-testicular sperm extraction were performed simultaneously. Motile spermatozoa were extracted from normal seminiferous tubules under microscopy and were frozen. Eventual intracytoplasmic sperm injection using the frozen spermatozoa is planned. Onco-testicular sperm extraction is an important fertility preservation method in patients with bilateral testicular tumors or a history of a previous contralateral orchiectomy.

Herein, we present a case of aortic root replacement 42 years after aortic valve replacement (AVR) with the Björk-Shiley Spherical (BSS) valve in a patient with an aortic root aneurysm. The patient was a 67-year-old man who had undergone AVR with BSS and aortic root enlargement for the treatment of infective endocarditis and aortic insufficiency at 25 years of age. He underwent aortic root replacement for an enlarged aortic root (73 mm). Under general anesthesia, median re-sternotomy was performed, and the BSS valve was removed. The valve functioned well with no pannus or thrombus. We performed an aortic root replacement using a composite graft consisting of a 24-mm mechanical valve and 30-mm artificial graft. We experienced a rare case of long-term durability of the BSS valve, which functioned well for 42 years.
