A 77-year-old woman underwent percutaneous coronary intervention (PCI) for chronic total occlusion of the left anterior descending artery using a drug-eluting stent (DES). Re-stenosis, stent fracture, and aneurysm were found on follow-up coronary angiography (CAG), and thus implantation of multiple DESs was required. Surgery was indicated because CAG 48 months after first DES implantation revealed enlargement of the aneurysm with other new lesions. She successfully underwent off-pump coronary artery bypass grafting and resection of the aneurysm.

A 62-year-old woman was referred to our hospital for treatment of hemolytic anemia 10 years after total arch replacement for acute aortic dissection. The cause of hemolysis was confirmed to be mechanical damage of red blood cells at the kinked graft. Because aortic valve regurgitation and occlusion of the left subclavian artery were also found, resection of the kinked graft, aortic valve replacement and reconstruction of the left subclavian artery were carried out concomitantly at reoperation. Her postoperative course was uneventful, and hemolysis resolved soon after the operation.

Kyukichoketsuin is commonly used for ki-deficiency and ketsu-deficiency, especially postpartum physical and mental complaints. However it does not contain ninjin and ogi, which are actually known to be major crude drugs for ki-deficiency. The 16th century Manbyokaishun gives many ways of treatment, some including the use of ninjin and ogi with kyukichoketsuin.
We report 2 cases treated with kyukichoketsuin and hokizai. The first case was a 33-year-old woman who had dyspnea with exertion and general malaise undergoing treatment for amenorrhea. The second case was a 39-year-old woman who had fatigue, irregular menstruation and headache after childbirth. We treated the first with kyukichoketsuin and hochuekkito extract, and the second with kyukichoketsuin and rikkunshito extract. In both cases, the symptoms improved remarkably over a few weeks with kyuchichoketsuin and hokizai. Thus, this combination therapy may have efficacy for gynecological symptoms with remarkable signs of ki-deficiency.

BACKGROUND/AIMS: Poor suction ability through a narrow working channel prolongs esophagogastroduodenoscopy (EGD). The aim of this study was to evaluate suction with a new ultrathin endoscope (EG-580NW2; Fujifilm Corp.) having a 2.4-mm working channel in clinical practice. METHODS: To evaluate in vitro suction, 200 mL water was suctioned and the suction time was measured. The clinical data of 117 patients who underwent EGD were retrospectively reviewed on the basis of recorded video, and the suction time was measured by using a stopwatch. RESULTS: In vitro, the suction time with the EG-580NW2 endoscope was significantly shorter than that with the use of an ultrathin endoscope with a 2.0-mm working channel (EG-580NW; mean +/- standard deviation, 22.7+/-1.1 seconds vs. 34.7+/-2.2 seconds; p<0.001). We analyzed the total time and the suction time for routine EGD in 117 patients (50 in the EG-580NW2 group and 67 in the EG-580NW group). In the EG-580NW2 group, the total time for EGD was significantly shorter than that in the EG-580NW group (275.3+/-42.0 seconds vs. 300.6+/-46.5 seconds, p=0.003). In the EG-580NW2 group, the suction time was significantly shorter than that in the EG-580NW group (19.2+/-7.6 seconds vs. 38.0+/-15.9 seconds, p<0.001). CONCLUSIONS: An ultrathin endoscope with a 2.4-mm working channel considerably shortens the routine EGD time by shortening the suction time, in comparison with an endoscope with a 2.0-mm working channel.

Background: Borderline resectable pancreatic adenocarcinoma (BR-PAC) isdefined as locally advanced tumor of the pancreas without metastasis that is,although potentially resectable (R), at high risk for positive resection marginfollowing surgery. The therapeutic strategy has remained unestablished becauseBR-PAC is biologically a heterogeneous subset in which the preoperativeprognostic factors are undetermined. Recently, several prognostic factors relatedto systemic inflammation have been explored in various kinds of cancers: thecombination of serum C-reactive protein (CRP) and albumin as the modifiedGlasgow prognostic factor; a combination of CRP and white blood cell countin the prognostic index; a combination of albumin and lymphocyte counts inOnodera’s prognostic nutritional index; the neutrophil-lymphocyte ratio (NLR);and the platelet-lymphocyte ratio (PLR). Although these prognostic factors havebeen explored in some small cohort studies of PAC patients, the results still remaincontroversial especially because PAC patients with diverse clinical stages wereincluded in the cohorts. It has never been reported whether or not the systemicinflammatory response is validated as a predictive risk factor in cohorts of onlyadvanced BR-PAC patients.Method: Between January 2003 and June 2012 at Kobe University Hospital,136 consecutive pancreatic adenocarcinoma (PAC) patients who underwentsurgical curative resection were retrospectively studied. Prior to surgery, the PACpatients were stratified into R- and BR-PAC patients according to the NationalComprehensive Cancer Network guidelines. To evaluate the independentprognostic significance of NLR and PLR, univariate and multivariate Coxproportional-hazard models were applied.Results: The median survival in PAC patients with preoperative NLR > 3 (n=45)and NLR < 3 (n=91) was 17.5 months and 31.1 months, respectively (P=0.0037).However, the median survival in PAC patients with PLR > 225 (n=32) and PLR< 225 (n=104) was 21.8 months and 26.2 months, showing no significantdifference in overall survival between the two groups (P=0.2526). The mediansurvival in the R-PAC patients with NLR > 3 (n=38) and NLR < 3 (n=70) was 18.1months and 33.1 months, respectively (P=0.0138). However, the median survivalin the R-PAC patients with PLR > 225 (n=27) and PLR < 225 (n=81) was 24.1months and 25.8 months, showing no significant difference in overall survivalbetween the two groups (P=0.6533). The median survival in BR-PAC patientswith preoperative NLR > 3 (n=7) and NLR < 3 (n=21) was 14.8 months and 27.2months, respectively (P=0.0068). In addition, median survival in BR-PAC patientswith preoperative PLR > 225 (n=5) and PLR < 225 (n=23) was 14.8 months and26.2 months, respectively (P=0.0050). Preoperative NLR > 3 (HR=21.437, 95%CI=4.119-142.980; P=0.0002) and PLR > 225 (HR=30.993, 95% CI=3.844-384.831; P=0.0009) were the only independent prognostic factors in BR-PACpatients.Conclusion: Preoperative NLR and PLR offer independent prognostic informationregarding overall survival in BR-PAC patients following curative resection. Theworkup is only to obtain a blood sample of 3 mL from PAC patients immediatelybefore treatment. In the near future, these factors associated with the systemicinflammatory response may have the potential to become criteria for BRPACcandidates to undergo neoadjuvant chemotherapy and/or neoadjuvantchemoradiation followed by surgical resection.

The small bowel had long been considered a dark unapproachable tunnel until the invention of capsule endoscopy and doubleballoon enteroscopy in the 21st century, which revolutionized the diagnosis and management of small bowel diseases, including bleeding. Various imaging modalities such as computed tomographic enterography, angiography, capsule endoscopy, and balloonassisted enteroscopy play vital roles in the diagnosis and management of small bowel bleeding. The choice of modality to use and timing of application differ according to the availability of the modalities, patient’s history, and physician’s experience. Small bowel bleeding is managed using different strategies as exemplified by medical treatment, interventional radiology, endoscopic therapy, or surgical intervention. Balloon-assisted enteroscopy enables endoscopic interventions to control small bowel bleeding, including electrocautery, argon plasma coagulation, clip application, and tattooing as a prelude to surgery. In this article, we clarify the recent approaches to the optimal diagnosis and management of patients with small bowel bleeding.

BACKGROUND/AIMS: Caudal-related homeobox 2 (Cdx2) is expressed in the human intestinal metaplastic mucosa and induces intestinal metaplastic mucosa in the Cdx2 transgenic mouse stomach. Atrophic gastritis and intestinal metaplasia commonly lead to gastric achlorhydria, which predisposes the stomach to bacterial overgrowth. In the present study, we determined the differences in gut microbiota between normal and Cdx2 transgenic mice, using quantitative reverse transcription-polymerase chain reaction (qRT-PCR). METHODS: Twelve normal (control) and 12 Cdx2 transgenic mice were sacrificed, and the gastric, jejunal, ileac, cecal and colonic mucosa, and feces were collected. To quantitate bacterial microbiota, we used real-time qRTPCR with 16S rRNA gene-targeted, species-specific primers. RESULTS: The total numbers of bacteria in the gastric, jejunal, ileac, cecal, and colonic mucosa of the Cdx2 transgenic mice were significantly higher than those of the normal mice. The Bacteroides fragilis group and also Prevotella were not detected in the stomach of the normal mice, although they were detected in the Cdx2 transgenic mice. Moreover, the Clostridium coccoides group, Clostridium leptum subgroup, Bacteroides fragilis group, and Prevotella were not detected in the jejunum or ileum of the normal mice, although they were detected in the Cdx2 transgenic mice. The fecal microbiota of the normal mice was similar to that of the Cdx2 transgenic mice. CONCLUSIONS: Our results showed the differences in composition of gut microbiota between normal and Cdx2 transgenic mice, which may be caused by the development of gastric achlorhydria and intestinal metaplasia in Cdx2 transgenic mice.

BACKGROUND/AIMS: SOX9 is a marker for stem cells in the intestine, and overexpression of SOX9 is found in gastric and colon cancer; however, the expression of SOX9 in nonampullary duodenal adenoma and adenocarcinoma has not yet been evaluated. This study aimed to investigate SOX9 expression in nonampullary duodenal adenoma and adenocarcinoma by immunohistochemistry. METHODS: We evaluated SOX9 expression in 43 clinical samples (nonampullary duodenal adenoma in 22 lesions and nonampullary duodenal adenocarcinoma in 21 lesions) resected under endoscopic mucosal resection or endoscopic submucosal dissection. RESULTS: SOX9 was expressed in part of the base of the normal duodenal mucosa surrounding adenomas and adenocarcinomas. In contrast, SOX9-positive cells were found in more than half of the crypts from the bottom part of the crypt in all of the 43 samples. Moreover, in 15 adenoma samples (68.2%) and 19 carcinoma samples (90.5%), SOX9 was expressed in more than three-quarters of the crypts from the bottom part of the crypt. CONCLUSIONS: SOX9 is overexpressed in nonampullary duodenal adenoma and adenocarcinoma in humans.
