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.

Endoventricular circular patch plasty (the Dor procedure) has been demonstrated to improve outcome in patients with ischemic cardiomyopathy. However, in some of them congestive heart failure (CHF) occurred during follow-up. This study examined the effects of the Dor procedure on the long-term survival and predictors of CHF after this procedure. Hemodynamic and clinical results were analyzed and predictors of CHF were examined. Postoperative ESVI in the CHF group was larger than that in the non-CHF group. The delayed MR rate was greater following the CHF group (82.4%) compared to the non-CHF group (19.2%). Despite mitral valve repair (N=8), 3 patients had delayed MR. All of them were greater than MR3. Hemodynamic and clinical results were improved by the Dor procedure. However, cardiac events were usually occurred during the follow-up. The predictor of CHF was delayed MR. Therefore, patients with preoperative MR should be treated. If preoperative MR is greater than 3, there will be MR recurrence cases after MVP only. Therefore, patients with preoperative MR (3 or 4) should be treated by alternative surgical procedures.

To improve the long-term clinical results of coronary artery bypass grafting, we evaluated our graft selections and the designs that were used, in relation to the quality of the anastomoses and patient backgrounds. We retrospectively reviewed the records of 505 patients who underwent isolated coronary artery bypass grafting involving more than 3 vessel reconstructions between May 1999 and March 2007. Neither the selection of a saphenous vein graft nor that of an internal thoracic artery graft was a statistically significant cardiac event factor. The cardiac event-free rates (at 1 and 5 years) according to anastomotic site were as follows : a) 92.9% and 76.6% for a radial artery graft and 93.2% and 83.9% for a saphenous vein graft at the right coronary artery ; b) 93.0% and 70.3% for a radial artery graft and 95.1% and 80.4% for a saphenous vein graft at the distal right coronary artery ; c) 94.5% and 77.8% for a left internal thoracic artery graft and 93.0% and available for a right internal thoracic artery graft at the left anterior descending artery ; d) 96.5% and 79.8% for a radial artery graft, 93.0% and 78.0% for a saphenous vein graft, and 91.3% and 75.6% for an internal thoracic artery graft at the left circumflex artery. Significant cardiac event factors were dialysis (risk ratio, 5.28 ; p<0.001), the use of a right gastroepiploic artery graft as the inflow blood vessel of a radial artery graft (risk ratio, 5.75 ; p=0.02), and off-pump coronary artery bypass grafting (risk ratio, 1.62 ; p=0.03). As a tendency toward more frequent early-stage cardiac events among patients with radial artery grafts was confirmed, careful follow-up is important for this group of patients. Right gastroepiploic artery grafts should be chosen carefully with full consideration of the anastomotic site quality and the flow demand, as the blood supply capability of such grafts is limited. For dialysis patients, although the mid-term clinical results are still being evaluated, a saphenous vein grafts have bwer early-stage of cardiac events. In younger patients, off-pump bypass is not the only treatment method available, and revascularization with extracorporeal circulation can reliably achieve good long-term results. To improve the long-term clinical results for coronary artery bypass grafts, graft selection and design should be carefully considered on a case-by-case basis. The quality of the anastomotic site and the patient background are important factors, especially with regard to the selection of a saphenous vein graft or a right gastroepiploic artery graft. A radial artery graft should be selected for use in relatively young patients because of its superior patency. Off-pump bypass may not necessarily be the treatment of choice in some cases because revascularization using extracorporeal circulation can reliably achieve better long-term results.

Purpose:
Total or proximal gastrectomy of the upper-third early gastric cancer (u-EGC) often causes severe post-gastrectomy syndrome, suggesting that these procedures are extremely invasive for patients without pathologically positive lymph node (LN) metastasis. This study aimed to evaluate the clinical applicability of a stomach function-preserving surgery, local resection (LR), with prophylactic left gastric artery (LGA)-basin dissection (LGA-BD).
Materials and Methods:
The data of patients with u-EGC (pathologically diagnosed as T1) were retrospectively analyzed. Total gastrectomy was performed in 30 patients, proximal gastrectomy in 45, and subtotal gastrectomy in 6; the LN status was evaluated assuming that the patients had already underwent LR + LGA-BD. This procedure was considered feasible in patients without LN metastases or in patients with cancer in the LGA basin. The reproducibility of the results was also evaluated using an external validation dataset.
Results:
Of the 82 eligible patients, 79 (96.3%) were cured after undergoing LR + LGA-BD, 74 (90.2%) were pathologically negative for LN metastases, and 5 (6.1%) had LN metastases, but these findings were only observed in the LGA basin. Similarly, of the 406 eligible tumors in the validation dataset, 396 (97.5%) were potentially curative. Tumors in the lesser curvature, post-endoscopic resection status, and small tumors (<20 mm) were considered to be stronger indicators of LR + LGA-BD as all subpopulation cases met our feasibility criteria.
Conclusions
More than 95% of the patients with u-EGC might be eligible for LR + LGA-BD.This function-preserving procedure may contribute to the development of u-EGC without pathological LN metastases, especially for tumors located at the lesser curvature.

Background: Mental assessment for patients in a palliative care unit with no regular psychiatrist tends to depend on subjective judgments by other health professionals. We introduced the 9-item Patient Health Questionnaire (PHQ-9) to screen major depression from patients in a palliative care unit and assessed the usefulness of the questionnaire. Methods: The subjects were all patients who were admitted to a palliative care unit. Each patient was asked to answer the PHQ-9 on admission and then was interviewed by a psychiatrist. When PHQ-9 score was of 10 points and above, the case was judged to be positive for depressive disorder. A psychiatrist diagnosed according to Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5). Results: A total of 83 patients were hospitalized between January 2016 and October 2016. 50 patients completed PHQ-9 and psychiatrist’s interview. Nine cases were positive by PHQ-9 and diagnosed as depressive disorder by a psychiatrist. Seven cases were positive by the PHQ-9 but not diagnosed as depressive disorder. Although 34 cases were judged to be negative by the PHQ-9, 2 cases of them were diagnosed as depressive disorder. The sensitivity and specificity of the PHQ-9 were 81.8% and 82.1% respectively. Conclusion: We found that the PHQ-9 was useful screening test for depression even in palliative care settings.

Introduction: several clinical training hospitals have their own resident mentor systems in Japan. However, the details and effects of the system still remain unclear. Objective: The aim of this study is to introduce Okayama University Hospital’s resident mentor system and to investigate its effectiveness based on mentees’ evaluations. Method: A questionnaire survey was conducted on residents using the system. Results: 32 (78.0%) of 41 residents used the system. 28 (87.5%) of them completed the survey, indicating most residents were satisfied with the currently-used system. Discussion: We will conduct a more detailed questionnaire survey for mentors and mentees to further improve the resident mentor system.

This case report describes our first experience performing percutaneous epicardial catheter ablation for Burugada syndrome in our hospital. We describe the good results achieved in this case. The patient was a man in his 30s with no remarkable medical history. However, his family history was notable for the sudden death of his grandfather at age 37 years and his father at age 27 years. While asleep, the patient experienced convulsions and lost consciousness. During emergency transportation, defibrillation was performed 7 times by the ambulance crew. When the patient arrived at our hospital, sinus rhythm was observed on ECG. During resuscitation, Burugada syndrome was diagnosed based on ECG findings. On hospital day 6, an internal cardioverter defibrillator was implanted. After discharge, the defibrillator operated 10 times, so we opted for ablation treatment. Fractionated potential of over 150 ms was confirmed in the right ventricular outflow tract. A low voltage zone of <1 mV could be mapped, and the same site was cauterized a total of 46 times. As a result, ST segment amplitude decreased significantly in lead V1 on ECG. Percutaneous epicardial catheter ablation performed with reference to Nademanee’s report achieved good results in this case of Burugada syndrome.
