We present a rare case of stent graft infection. A 69-year-old man, who had undergone endovascular repair of an abdominal aortic aneurysm with an Inoue stent graft 5 years previously, was admitted with high-grade fever. An abscess around an abdominal aortic aneurysm was found on abdominal computed tomography (CT) and he was given a diagnosis of stent graft infection. The stent graft was removed and vascular reconstruction was performed using a Gelweave graft bonded with rifampicin. The graft was then covered with the greater omentum, and he was discharged on the 27th postoperative day.

Purpose: We report two patients receiving high doses of systemic opioids in whom gradual switching of the opioid administration route from systemic to intrathecal provided satisfactory pain relief without excessive sedation or withdrawal symptoms. Case reports: In one of the patients, who was already receiving 500mg morphine intravenously but still suffered from right upper quadrant pain, it was difficult to increase the opioid dosage according to the WHO guidelines because of intolerable side effects. The other patient, in spite of taking a combination of systemic opioids equivalent to 760mg oral morphine, had inadequate pain relief and could not continue receiving home medical care. In both cases we could successfully change from systemic to intrathecal opioid administration in a step-wise manner without deterioration of pain control, adverse effects due to over dosage, or withdrawal symptoms. Intrathecal opioid administration also reduced drowsiness and improved daily activity. Conclusion: Currently, there are no guidelines for change of route of opioid administration from systemic to intrathecal administration and few published reports have concretely documented opioid route switching in Japan. A carefully planned, step-wise switching of opioid administration route from systemic to intrathecal should be considered in patients who are already taking high doses of systemic opioids.

Introduction : As one of the strategies for the introduction of collaborative drug therapy management (CDTM) into a community healthcare system in Japan, we constructed a ‘positive list’ which was agreed by a family physician in advance, and subsequently validated the effects on healthcare insurance fees, the number of prescription question and the changes of utilization rate for generic drugs.
Methods : The items that replaced prescription questions with regard to ex post facto approval were defined as ‘Resolved Questions’ in our constructed positive list. By adopting the ‘Resolved Questions’, we then examined the effect on healthcare insurance fees, prescription questions and the changes of utilization rates for generic drugs.
Results : Among all prescription questions accepted from January through May 2012 inclusive, 178 (22.7%) were ‘Resolved Questions’, without there being change in the therapeutic strategies by the prescribing physicians. During this period, 17,455 healthcare insurance fees were reduced. In addition, the utilization rate for generic drugs were increased up to 46.6%.
Conclusion : The reduction of healthcare insurance fees, prescription questions and the increased utilization rates of generic drugs were facilitated by prudent pharmacist judgements based on ‘Resolved Questions’.

Purpose:
Despite annual endoscopy, patients with metachronous remnant gastric cancer (MRGC) following proximal gastrectomy (PG) are at times ineligible for endoscopic resection (ER). This study aimed to clarify the clinical risk factors for ER inapplicability.
Materials and Methods:
We reviewed the records of 203 patients who underwent PG for cT1 gastric cancer between 2006 and 2015. The remnant stomach was categorized as a pseudofornix, corpus, or antrum.
Results:
Thirty-two MRGCs were identified in the 29 patients. Twenty MRGCs were classified as ER (ER group, 62.5%), whereas 12 were not (non-ER group, 37.5%). MRGCs were located in the pseudo-fornix in 1, corpus in 5, and antrum in 14 in the ER group, and in the pseudofornix in 6, corpus in 4, and antrum in 2 in the non-ER group (P=0.019). Multivariate analysis revealed that the pseudo-fornix was an independent risk factor for non-ER (P=0.014). In the non-ER group, MRGCs at the pseudo-fornix (n=6) had more frequent undifferentiated-type histology (4/6 vs. 0/6), deeper (≥pT1b2; 6/6 vs. 2/6) and nodal metastasis (3/6 vs. 0/6) than non-pseudo-fornix lesions (n=6). We examined the visibility of the region developing MRGC on an annual follow-up endoscopy one year before MRGC detection. In seven lesions at the pseudofornix, visibility was only secured in two (28.6%) because of food residues. Of the 25 lesions in the non-pseudo-fornix, visibility was secured in 21 lesions (84%; P=0.010).
Conclusions
Endoscopic visibility increases the chances of ER applicability. Special preparation is required to ensure the complete clearance of food residues in the pseudo-fornix.
