We present a very rare case of abdominal aortic aneurysm associated with paraplegia. A 68-year-old man developed paraplegia following resection of a infrarenal abdominal aortic aneurysm. The aorta was clamped just below the renal arteries. In this case interruption of the radicular artery magna (RAM; Adamkiewicz artery) might have caused serious ischemia of the spinal cord. Spinal cord ischemia is a very rare and unpredictable complication in surgery of infrarenal abdominal aortic aneurysms because the spinal cord is generally protected from irreversible ischemia during infrarenal aortic occlusion by the presence of the RAM which arises above the renal artery (Even if RAM interruption might arise, the lower renal artery, and other radicular arteries are usually present above the renal arteries). We feel that reducing aortic cross-clamping time as short as possible and avoiding intra- and postoperative hypotensive episodes to keep adequate blood flow of collaterals seem to be the most important factors to prevent spinal cord ischemia.

BACKGROUND/AIMS: In capsule endoscopy (CE), the capsule does not always reach the cecum within its battery life, which may reduce its diagnostic yield. We evaluated the effect of mosapride citrate, a 5-hydroxytryptamine-4 agonist that increases gastrointestinal motility, on CE completion. METHODS: In a retrospective study, we performed univariate and multivariate analyses for 232 CE procedures performed at our hospital. To identify factors that affect CE completion, the following data were systematically collected: gender, age, gastric transit time (GTT), nonsteroidal anti-inflammatory drug administration, previous abdominal surgery, hospitalization, use of a polyethylene glycol solution, use of mosapride citrate (10 mg), body mass index (BMI), and total recording time. RESULTS: The univariate analysis showed that oral mosapride citrate, GTT, and BMI were associated with improved CE completion. Multivariate analyses showed that oral mosapride citrate (odds ratio [OR], 1.99; 95% confidence interval [CI], 1.01 to 3.91) and GTT (OR, 2.34; 95% CI, 1.13 to 4.87) were significant factors for improving the CE completion. Oral mosapride citrate significantly shortened the GTT and small bowel transit time (SBTT). CONCLUSIONS: Oral mosapride citrate reduced the GTT and SBTT during CE and improved the CE completion rate.

The incidence and prevalence of inflammatory bowel diseases (IBDs) including ulcerative colitis and Crohn disease are rapidly increasing in Western countries and in developed Asian countries. Although biologic agents targeting the immune system have been effective in patients with IBD, cessation of treatment leads to relapse in the majority of patients, suggesting that intrinsic immune dysregulation is an effect, not a cause, of IBD. Dramatic changes in the environment, resulting in the dysregulated composition of intestinal microbiota or dysbiosis, may be associated with the fundamental causes of IBD. Japan now has upgraded water supply and sewerage systems, as well as dietary habits and antibiotic overuse that are similar to such features found in developed Western countries. The purpose of this review article was to describe the association of diet, particularly Japanese food and microbiota, with IBD.

Although ileocolonoscopy is the gold standard for diagnosis of inflammatory bowel disease and is useful for assessing the disease severity in the colon and terminal ileum, several alternative diagnostic techniques have been developed recently. For ulcerative colitis (UC), magnification colonoscopy, endocytoscopy, and confocal laser endomicroscopy enable assessment of histological inflammation without the need for biopsy. Capsule endoscopy is useful for detection of small intestinal and colonic lesions in both female and male patients. For UC, capsule endoscopy may be useful for evaluating colonic inflammation in patients with a previous poor colonoscopy experience, while it should be used only in Crohn's disease (CD) patients with unexplained symptoms when other examinations are negative. Magnetic resonance enterography (MRE) is particularly useful for detecting transmural inflammation, stenosis, and extraintestinal lesions, including abscesses and fistulas. MRE is also useful when evaluating small and large intestinal lesions, even in cases with severe strictures in which full evaluation of the small bowel would be virtually impossible using other devices. Therefore, the appropriate diagnostic devices for detecting CD lesions in the small and large intestine should be used.

Background/Aims:
Endoscopic resection of all colorectal adenomatous lesions with a low complication rate, simplicity, and negative residuals is challenging. Hence, we developed a new method called “non-injection resection using bipolar soft coagulation mode (NIRBS)” method, adapted for colorectal lesions. In addition, we evaluated the effectiveness of this method.
Methods:
We performed NIRBS throughout a 12-month period for all colorectal lesions which snare resection was acceptable without cancerous lesions infiltrating deeper than the submucosal layer.
Results:
A total of 746 resected lesions were included in the study, with a 4.5 mm mean size (range, 1–35 mm). The major pathological breakdowns were as follows: 64.3% (480/746) were adenomas, and 5.0% (37/746) were intraepithelial adenocarcinomas (Tis lesions). No residuals were observed in any of the 37 Tis lesions (mean size, 15.3 mm). Adverse events included bleeding (0.4%) but no perforation.
Conclusions
NIRBS allowed the resection of multiple lesions with simplicity because of the non-injection and without perforating due to the minimal burn effect of the bipolar snare set in the soft coagulation mode. Therefore, NIRBS can be used to resect adenomatous lesions easily, including Tis lesions, from small to large lesions without leaving residuals.

Background/Aims:
Mucosal healing (MH) of distal lesions in ulcerative colitis (UC) has recently been confirmed with budesonide 2-mg foam (BF) treatment in 2 clinical trials; however, few studies have investigated the predictive factors for complete MH.
Methods:
We conducted a post hoc analysis using pooled data from phase II and III clinical trials evaluating the efficacy and safety of BF for UC. Additionally, we analyzed the relationships between complete MH and baseline factors and clinical symptoms from baseline to week 6.
Results:
Among the 291 Japanese patients from the 2 pooled clinical studies, 119 patients in the BF twice a day group and 117 in the placebo group were included in the full analysis set. The proportion of patients with a rectal bleeding (RB) subscore of 0 was significantly higher in the BF group than in the placebo group after a 5-day treatment (P<0.05). After a 2-day treatment, significantly more patients in the BF group had a stool frequency (SF) subscore of 0 than patients in the placebo group (P<0.05). Multivariate analysis showed that complete MH at week 6 was influenced by baseline SF subscore and 5-aminosalicylic acid (5-ASA) enema or suppository use (P=0.0086 and P=0.0015, respectively). The relationship between complete MH at week 6 and RB subscore after week 2 was also confirmed.
Conclusions
Normal SF at baseline, history of 5-ASA topical product use, and elimination of RB after week 2 are suggested predictors of complete MH at week 6 with twice-daily BF treatment.

Splenic pseudoaneurysm rupture is a serious condition that sometimes leads to death. Pseudoaneurysm rupture is often treated with transcatheter arterial embolization (TAE), after which the re-rupture rate is 18%–37%. A 59-year-old man presented with back pain, and contrast-enhanced computed tomography (CECT) revealed pancreatic tail cancer with multiple liver metastases. After three courses of chemotherapy, CECT revealed good response with shrinkage of the tumors. However, the patient had back pain and CECT revealed pancreatic pseudocyst with pseudoaneurysm rupture. He underwent angiography, wherein the splenic artery pseudoaneurysm was embolized using TAE. Subsequently, pseudocyst drainage was performed using lumen-apposing metal stent (LAMS) to prevent pseudoaneurysm re-rupture. Thereafter, the pseudocyst shrieked with decreased serum levels of C-reactive protein, allowing the patient to re-institute chemotherapy. Pseudocyst drainage using LAMS was safe and effective when the pancreatic pseudoaneurysm had a high-risk rebleeding due to exposure to pancreatic juice.
