This paper reports three cases of malignant afferent loop obstruction after choledochojejunostomy. In the first case, a 75-year old woman, who had undergone left hepatectomy for bile duct cancer with bile duct resection, was admitted for Roux en Y reconstruction after choledochojejunostomy because of emesis. The local recurrent tumor caused occlusion of the duodenum and afferent limb, and bypass surgery was performed after transintestinal drainage. In the second case, a 57-year-old man, who had undergone pancreaticoduodenectomy for pancreas cancer, was hospitalized with a high-grade fever and epigastric pain. Exploratory laparotomy revealed widespread carcinomatosis causing afferent loop obstruction, and bypass surgery was performed. In the third case, a 60-year-old woman with paraaortic lymphnode recurrence of gallbladder cancer was admitted as she had afferent loop syndrome. Transintestinal drainage was performed. All these three patients were discharged. Bypass surgery for selective patients turned out to be an effective palliative treatment for malignant afferent loop obstruction.

Objective: A hospital Formulary (HF) is useful not only for providing a list of formulary drugs, but also for drug safety management and clinical practice in hospitals. Our Pharmacy Division serves as a clinical training facility for the Faculty of Medicine and offers a bedside learning (BSL) program that allows students to participate in medical services. Providing medical students with a requisite understanding of pharmacotherapy in order to effectively provide medical services is the goal of the core curriculum of medical education and HF use in BSL may be effective in achieving this goal. We conducted a survey in order to examine the usefulness of an HF for medical students during clinical training and to determine what drug information is required by students.
Methods: Between April 2012 and March 2013, a questionnaire survey was conducted on 88 fifth-year medical students who participated in a 1-day BSL program using an HF.
Results: The response rate was 100%. All students responded that they understood how to use the HF and believed it was useful in BSL. However, the level of satisfaction with the explanatory notes was significantly lower than that of other sections providing clinically useful additional information such as monographs or supplementary tables (p<0.05). More than 80% of the students considered monographs to be useful for obtaining information on side effects, warnings and contraindications, dosage and administration, indications, dosing in renal impairment, and drug name. Students generally considered supplementary tables useful for obtaining information on serious side effects and their early identification, points of drug use in renal dysfunction, appropriate drug use in cancer chemotherapy, insulin and diabetes treatment, calculations of pediatric dosing, and a list of clinically used abbreviations.
Conclusion: These results suggest that medical students believe an HF is useful in BSL. When medical students participate in pharmacotherapy during BSL programs outside the Pharmacy Division, an HF that not only lists drugs but also contains supplementary tables of clinically useful information may be required.

Purpose: To compare the effects of aging in patients with acute myocardial infarction (AMI) on their clinical background and hospitalization progress, and to examine the relationships between age and these factors.
Subject: One hundred and fifty-three patients who experienced cardiac rehabilitation after percutaneous coronary intervention (PCI) (63.8±11.1 y.o, 126 men, 27 women).
Method: The patients were divided into the middle aged group (<65 y.o, n=84), young old group (65 to 74 y.o, n=44), and old group (75 y.o≥ n=25). The differences between groups were examined in respect of 13 items about clinical backgrounds (responsibility coronary arteries, CKmax, LVEF, residual stenosis, hypertension, diabetes, hyperlipemia, smoking, and BMI) and hospitalization progress (cardiac complications, locomotorium disabilities, abnormality as 200mECG, and duration of hospitalization).
Results: Left veticular ejection fraction (LVEF) was significantly lower in the old group than in the young old group. The old group had a high rate of residual stenosis. In the coronary risk factors, all of the groups had hypertension at a high rate of 54.5% or over. The middle aged group and young old group had diabetes at about 38%. The middle aged group was prone to hyperlipemia, and had significantly a high smoking rate. Body mass index (BMI) was significantly higher in the middle aged group than in the old group. In hospitalization progress, the old group had a high rate of cardiac complications and locomotorium disability. The duration of hospitalization was significantly longer in the old group than in the other groups.
Conclusion: It would be necessary to give middle-aged persons educational guidance for the improvement of the coronary risk factors, and to provide the old persons with the suitable rehabilitation programs considering various complications.

In the United States, the concepts of “Pay For Performance” and “Value-Based Health Care” were introduced, and it has been taken up as the way forward for the American health care systems. As one of the measures, an Accountable Care Organization (ACO) was included in the federal Affordable Care Act, and are being promoted for the purpose of balancing cost savings and good quality assurance in the healthcare field. In this manuscript, we provide an overview of the system of ACO, which is one of the value-based health care systems and was introduced with the aim of balancing cost savings and good quality assurance of medical care, and also focus on the role of pharmacists in ACO and summarize their roles they are executing and expected. Furthermore, we discuss on what we should learn from the United States in considering the ideal medical care systems in Japan.

The objective of this study was to evaluate the magnified endoscopic findings in the diagnosis of follicular lymphoma in the small intestine in comparison with those of intestinal follicular lymphoma and lymphangiectasia. Four patients with follicular lymphoma and 3 with lymphangiectasia in the small intestine were retrospectively analyzed. A prototype magnifying singleballoon enteroscope was used. The findings of the intestinal follicular lymphoma and lymphangiectasia were retrospectively analyzed to determine the magnified endoscopic findings of follicular lymphoma in the small intestine. Opaque white granules were observed in 3 of the 4 patients with follicular lymphoma. Magnified narrow-band imaging (NBI) of the opaque white granules showed stretched microvessels, which had a diminutive tree-like appearance. The remaining patient had no opaque white granules and only displayed whitish villi. Magnified NBI observation of the whitish villi revealed the absence of marginal villus epithelium, which was confirmed by histology. The magnified NBI enteroscopy revealed the diminutive tree-like appearance on the opaque white granules and the absence of marginal villus epithelium of the whitish villi in intestinal follicular lymphoma. These findings may be useful in diagnosing follicular lymphoma.

A woman in her 80s who had difficulty walking due to back pain was admitted to our hospital. Until two months earlier, she had been able to live independently in daily life. She was not severely constipated, did not take laxatives, and had not received an enema or undergone stool extraction. She had no abdominal symptoms, such as abdominal pain or distension. Surprisingly, however, computed tomography showed lower rectal perforation with subcutaneous emphysema in the pelvic retroperitoneum, hip, and left inguinal region. Therefore, we urgently performed abdominoperineal resection to save her. The lower rectum is a relatively uncommon site of perforation in the large intestine, and nontraumatic cases are rare. Elderly patients in particular may have only atypical symptoms and thus require careful attention.

We report the case of a 76-year-old man who developed type IA endoleak through the fenestration after 1-debranch TEVAR using a Najuta endograft. The patient was admitted with expansion of the aneurysm after TEVAR, for additional therapy. Type IA endoleak through a fenestration has remained a significant clinical concern and its treatment is challenging. We performed Zone 0 TEVAR using the “Squid-Capture” technique assisted in situ stent-graft fenestration. Cerebral vessels were perfused by a percutaneous cardiopulmonary support system during in situ stent-graft fenestration, and the cerebral branch was clamped at the proximal site. It is difficult to operate the catheter inside the endoskeleton structure of a Najuta endograft, but several innovations were effective. Test dilation of the balloon catheter was performed to ensure that the wire did not interfere with the endoskeleton. Avoiding interference with the endoskeleton is important. The Squid-Capture technique allows safe and secure puncture of the graft. The operation was completed successfully. After this procedure, the endoleak disappeared. It is considered to be a useful method for treatment of endoleak through the fenestration.
