Ninety patients with abdominal aortic aneurysm underwent endovascular stent grafting in our hospital between 2001 and 2006 and two patients required graft replacement of abdominal aortic aneurysms during the late postoperative phase. Case 1 was a 77-year-old man for whom endovascular stent grafting for an abdominal aortic aneurysm and thoracic aortic aneurysm had been performed concomitantly. Six months later, because the abdominal aortic aneurysm had expanded from 68mm to 75mm in diameter, due to a type I endoleak which was detected postoperatively, he underwent open surgery. An occlusion balloon was inflated at the proximal site of the celiac artery until the stent graft was extracted. After positioning the aortic clamp below the origin of the renal arteries, a bifurcated graft was implanted. The postoperative course was uneventful. Case 2 was an 86-year-old woman who had undergone endovascular stent grafting for an abdominal aortic aneurysm. The endovascular procedure was successful and no endoleak was detected postoperatively. However, 13 months later, a community hospital admitted her in a state of shock due to ruptured abdominal aortic aneurysm. She was transferred to our hospital and underwent an emergency operation. Because insertion of an occlusion balloon into the brachial artery failed, we primarily performed supravisceral aortic cross clamping. After opening the aneurysm sac, the stent graft was removed and a bifurcated graft was implanted. After declamping, we found that the right common iliac artery was occluded, and therefore aorto-right external iliac bypass grafting was then also performed. The postoperative course was uneventful.

Objective : The aim of this study is to describe a series of patients undergoing reoperation due to hemolytic anemia after mitral valve surgery and assess the mechanisms and surgical outcomes. Methods : Between 2009 and 2014, we performed redo mitral valve surgery in 11 patients who had refractory hemolytic anemia after mitral valve surgery at Kyoto University Hospital. The mean age of the patients was 72.2±6.8 years old, and there were 5 men. Results : Preoperative echocardiography demonstrated that only 3 patients had ≥ grade 3 mitral regurgitation (MR), the rest of the patients had only mild to moderate MR. The mechanisms of severe hemolysis included paravalvular leakage (PVL) after mitral valve replacement (MVR) in 8 patients, structural valve deterioration (SVD) after MVR using a bioprosthesis in one, and residual/recurrent mitral regurgitation after mitral valve plasty (MVP) in two. All the patients except one (re-MVP) underwent MVR. The mean interval between previous operation and current operation was 14.1±9.4 years in post-MVR cases, and 2.0±1.9 years in post-MVP cases. There were three late deaths, one of which was due to cardiac death (exacerbation of heart failure due to pneumonia). There was one patient who required re-MVR for recurrent hemolysis due to PVL after MVR. Conclusion : Although hemolytic anemia after mitral valve surgery is rare, it often requires reoperation regardless of the degree of MR at late follow-up period. Thus, patients after mitral valve surgery should be carefully followed-up.

Objective: To compare effects of the fluoropyrimidines S-1 and capecitabine on prothrombin time international normalized ratios (PT-INR) of warfarin following coadministration and after discontinuation of each fluoropyrimidine treatment.
Methods: Medical records of patients receiving warfarin with either S-1 (6 patients) or capecitabine (7 patients) were obtained from four hospitals.
Results: Increased PT-INR was observed until peak levels of warfarin were achieved in all patients in S-1 and capecitabine treatment groups. Moreover, PT-INR significantly changed after coadministration within each group (p<0.05). Specifically, ratios of peak PT-INR after coadministration of each fluoropyrimidine and those following administration of warfarin alone (PT-INR elevation ratio) were 3.31 and 3.29 in S-1 and capecitabine coadministration groups, respectively. Moreover, numbers of days to peak PT-INR were 38.3 and 31.3 days, respectively, and did not significantly differ between the treatment groups. Furthermore, PT-INR returned to pretreatment levels by 17.5 and 15.1 days after discontinuation of S-1 and capecitabine, respectively, and did not significantly differ between the treatment groups.
Conclusion: Coadministration of S-1 and capecitabine similarly prolongs PT-INR by approximately 3-fold compared with administration of warfarin alone; therefore, these drug-drug interactions were clinically suggested to be of high risk for episodes of bleeding and remarkable alterations in coagulation parameters. Therefore, blood coagulation ability should be more carefully monitored with regard to PT-INRs in patients receiving warfarin with S-1 or capecitabine not only during coadministration but also after discontinuation of fluoropyrimidine treatments.

Purpose:
Stress urinary incontinence is a postoperative complication occurring in patients with pelvic organ prolapse (POP). Although the 1-hour pad test measures the degree of urinary incontinence qualitatively and quantitatively, some elderly women undergoing POP surgery do not have the daily activities of living to perform the pad test. Therefore, we examined whether the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) could be used as an alternative tool for pad tests.
Methods:
We retrospectively evaluated 132 patients with POP. In our hospital, 57 patients were treated by laparoscopic sacrocolpopexy (LSC), whereas 75 were treated by transvaginal mesh surgery (TVM). We measured the changes in symptoms preand postoperatively using the ICIQ-SF and 1-hour pad weight testing, and investigated the correlation between the total plus component question scores of the ICIQ-SF and 1-hour pad weight.
Results:
The preoperative ICIQ total scores in all patients decreased significantly as the amount of leakage on the 1-hour pad weight decreased. The component question scores also decreased significantly with decreasing levels of 1-hour pad weight. The LSC and TVM groups had decreased ICIQ-SF total and component question scores as pad weight decreased. At 12 months postoperatively, the ICIQ total scores in all patients significantly declined as the amount of leakage on the 1-hour pad weight decreased. In the LSC group, the ICIQ-SF total and component question scores also decreased with decreased pad weight, but the differences were not always significant between ICIQ scores and pad weight. In the TVM group, the ICIQ-SF total and component question scores also significantly decreased as the pad weight decreased.
Conclusions
The ICIQ-SF could be an appropriate substitute for the 1-hour pad weight testing in predicting the severity of urinary incontinence. In the future, we hope to predict the level of urine leakage based on the ICIQ-SF score.
