A 75-year-old man received a diagnosis of an abdominal aneurysm and underwent abdominal aortic replacement. His left internal iliac artery was sacrificed because of the difficulty of reconstruction. Rhabdomyolysis of the left gluteus muscle resulted in acute renal failure (ARF) postoperatively. Continuous hemodiafiltration (CHDF) was performed from postoperative day (POD) 1 through POD 10 for the management of his ARF. During CHDF, the maximum value of serum creatinine was 5.10 mg/dl and it returned to the normal range of 1.10 mg/dl on POD 20. We conclude that the early deployment of CHDF was effective in rhabdomyolysis-induced ARF.

The aim of this study was to clarify the comorbidities of patients with Leriche syndrome and ischemic heart disease. We enrolled 26 patients with Leriche syndrome and who had undergone preoperative coronary angiography were enrolled. The comorbidities of diabetes, hypertension, and coronary artery disease developed in more than half of Leriche patients with Leriche syndrome. Marked coronary artery disease was diagnosed in 14 patients, 7 of whom underwent coronary artery bypass surgery. The Revascularization procedures performed in patients with Leriche syndrome were anatomical aortofemoral bypass in 15 and an extra-anatomical axillofemoral bypass in 9. In 2 cases of extra-anatomical bypass, occlusion developed in the long-term.

It has been demonstrated that atrial fibrillation (AF) frequently occurs after coronary artery bypass grafting (CABG) and may cause cerebral infarction. The purpose of this research is to clarify the risk factors of AF in patients who underwent off-pump CABG (OPCABG). In this study, 142 patients (111 men and 31 women) were enrolled with an average age of 67 years old (range, 33-83). According to multivariate analysis, age and the preoperative peak early (E)/late (A) diastolic velocities ratio (E/A) were the independent predictors of postoperative AF. Patients who suffered from postoperative AF required a significantly longer hospital stay.

BACKGROUND/AIMS: Peyer's patches (PPs) are aggregates of lymphoid follicles that are mainly located in the distal ileum; they play a major role in mucosal immunity. We recently reported that patients with ulcerative colitis (UC) have alterations in PPs that can be detected using narrow-band imaging with magnifying endoscopy (NBI-ME). However, the usefulness of NBI-ME in UC treatment as a whole is still unknown. METHODS: We collected NBI-ME images of PPs from 67 UC patients who had undergone ileocolonoscopy. We evaluated changes in the villi using the "villi index," which is based on three categories: irregular formation, hyperemia, and altered vascular network pattern. The patients were divided into two groups on the basis of villi index: low (L)- and high (H)-types. We then determined the correlation between morphological alteration of the PPs and various clinical characteristics. In 52 patients who were in clinical remission, we also analyzed the correlation between NBI-ME findings of PPs and clinical recurrence. RESULTS: The time to clinical recurrence was significantly shorter in remissive UC patients with H-type PPs than in those with L-type PPs (P<0.01). Moreover, PP alterations were not correlated with age, sex, disease duration, clinical activity, endoscopic score, or extent of disease involvement. Multivariate analysis revealed that the existence of H-type PPs was an independent risk factor for clinical recurrence (hazard ratio, 3.3; P<0.01). CONCLUSIONS: UC patients with morphological alterations in PPs were at high risk of clinical relapse. Therefore, to predict the clinical course of UC, it may be useful to evaluate NBI-ME images of PPs.
