Eosinophilic gastroenteritis is a rare disease in which the symptoms are associated with eosinophilic infiltration in various layers of the gastrointestinal tract. A 56-year-old man complained of severe abdominal pain after eating yellow tail fish and oyster. There was no peripheral blood eosinophilia in the initial laboratory test. Abdominal computed tomography demonstrated circumferential wall thickening and dilatation of small intestine with ascites. An emergency laparotomy accompanied by segmental resection of the ileum and end-to-end anastomosis was performed. Histologically, there was a dense infiltration of eosinophils throughout the entire layers of ileal wall, through which this case could be diagnosed as eosinophilic enteritis. We did not prescribe systemic glucocorticosteroid, but asked him to avoid fish and oyster. He did not complain of recurrent gastrointestinal symptoms anymore after discharge. This is the case of eosinophilic gastroenteritis with intestinal obstruction requiring emergency surgery, which was developed or aggravated after ingestion of yellow tail fish and oyster that were suspected to be culprit foods. In patients with eosinophilic gastroenteritis, foods which are related to this abnormal condition should be identified and avoided to control this disease and prevent from aggravation or flare-up.

OBJECTIVE: Efficacy or long-term result of metastasectomy for recurrent or metastatic biliary tract carcinoma (BTC) is not well established. We conducted a retrospective review of the outcomes of metastasectomy for recurrent or metastatic BTCs. METHODS: The clinicopathological features and outcomes of consecutive patients with BTCs who underwent surgical resection for primary and metastatic disease at a tertiary referral hospital from 2003 to 2013 were reviewed retrospectively. RESULTS: We found 19 eligible patients. Median age of patients was 57 years old (range, 27 to 68 years old), and 11 patients (58%) were female. Primary sites were gallbladder cancer (seven patients, 37%), intrahepatic cholangiocarcinoma (five patients, 26%), distal common bile duct cancer (three patients, 16%), proximal common bile duct cancer (two patients, 11%), and ampulla of Vater cancer (two patients, 11%). Eight patients (42%) had synchronous metastasis, while 11 (58%) had metachronous metastasis. The most common metastatic site was liver (nine patients, 47%), lymph node (nine patients, 47%), and peritoneum (three patients, 16%). Nine patients (47%) achieved R0 resection, while four (21%) and six (32%) patients had R1 and R2 resection, respectively. With a median follow-up period of 26.7 months, the estimated median overall survival (OS) was 18.2 months (95% confidence interval [CI], 13.6 to 22.9 months). Lower Eastern Cooperative Oncology Group performance status (P=0.023), metachronous metastasis (P=0.04), absence of lymph node metastasis (P=0.009), lower numbers of metastatic organs (P<0.001), normal postoperative carbohydrate antigen 19-9 level (P=0.034), and time from diagnosis to metastasectomy more than one year (P=0.019) were identified as prognostic factors for a longer OS after metastasectomy. CONCLUSION: For recurrent or metastatic BTCs, metastasectomy can be a viable option for selected patients.

BACKGROUND: The selective media for culture of Helicobacter pylori(H. pylori) are Egg yolk emulsion medium, modified Thayer-Martin medium and Skirrow's medium. The non-selective media for culture of H. pylori are brucella agar, trypticase soy agar, and brain heart infusion agar. The selective media are more expensive and difficult to prepare than non-selective media, whereas non-selective media are difficult to isolate H. pylori due to contamination of upper respiratory tract bacteria. The objects of this study are to reduce upper respiratory contaminants by use of HCl-KCl buffer (H-K buffer) for primary isolation, and to compare with culture, CLO test, histologic examination and H. pylori IgG antibodies. METHODS: Seventy one patients underwent upper gastrointestinal endoscopy with biopsy. For 32 patients, two biopsies were taken from antrum: One for direct inoculation into blood agar plate, the other for pretreatment of H-K buffer. For fifty six patients, we performed culture, CLO test, histology, and H. pylori IgG. RESULTS: 1) Among the 32 patients, H. pylori were isolated in 25 patients (23 patients for direct inoculation and 25 patients for H-K pretreatment). Twelve cases among H-K buffer treatment group did not show contamination, whereas only two among direct inoculation group showed no contamination. The average number of contaminating colony forming unit (CFU) of direct inoculation and H-K buffer treatment were 77 and 9, respectively. 2) The positive rates of culture and CLO test, histology, and H. pylori IgG for H. pylori infection were 71.4%, 67.9%, 75.0%, and 57.1%, respective

Purpose:
Heart failure (HF) poses significant morbidity and mortality. Recently, the ventriculo-vascular coupling index (VVI) was introduced as an independent prognostic factor reflective of the overall cardiovascular performance index in HF. We aimed to determine the effectiveness of force-titration of valsartan on VVI values in HF patients.
Materials and Methods:
In this multicenter and prospective observational trial, the effect of valsartan was stratified according to dosages [non-ceiling dose (NCD) vs. ceiling dose (CD)] in HF patients with left ventricular ejection fraction (LVEF) <55%. Biochemical studies, including N-terminal pro-B-type natriuretic peptide (NT-proBNP), echocardiography with VVI, the treadmill test, and the activity scale index were assessed at baseline and after 24 weeks of treatment.
Results:
One-hundred thirty-eight patients were force-titrated to either a CD group (n=81) or a NCD group (n=57). The mean age of the study participants was 59 years and 66% were male. After 6 months of follow up, left ventricular mass index (LVMI) values had significantly improved in the CD group but not in the NCD group. Intriguingly, in HF patients with a reduced ejection fraction (HFrEF) (n=52, LVEF <40%), a significant improvement in VVI was only observed in the CD group (from 2.4±0.6 to 1.8±0.5, p<0.001).
Conclusion
CDs of valsartan for 6 months showed better improvement in VVI, as well as LVMI, in patients with HFrEF, compared with NCDs.

Xanthogranulomatous inflammation (XGI) is characterized histologically by the deposition of foamy macrophages and infiltration of inflammatory cells. While XGI is extremely rare, it has been reported in the gallbladder, kidney, stomach, and lymph nodes. A 61-year-old woman presented with epigastric pain for 2 weeks. Abdominal computed tomography and magnetic resonance imaging showed a pancreatic head mass with distal common bile duct wall thickening. Endoscopic ultrasonography followed by fine needle aspiration was performed, and subsequent pathology report revealed a benign disease. Because uncontrolled abdominal pain persisted and possibility of malignancy could not be excluded, Whipple's operation was eventually performed, and pathology report showed xanthogranulomatous pancreatitis (XGP). Herein, we report a case of symptomatic XGP mimicking of pancreas cancer. Although XGP is extremely rare, it should be considered as a differential diagnosis of neoplastic lesions of the pancreas.

Abalone is popular seafood in Asia; however, allergy to abalone was rarely reported. We report a case of anaphylaxis after consumption of abalone. A 24-year-old female visited an Emergency Department, complaining of cough, dyspnea, rhinorrhea, generalized urticaria, facial edema, and wheezing that had developed 1 hour after consumption of abalone. She was discharged when her symptoms subsided after antihistamine and dexamethasone were given. One month later, she was referred to our outpatient clinic. We performed skin prick tests, measurement of serum specific IgE antibody level, and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) with IgE immunoblotting. Both skin prick and specific IgE antibody tests were positive for abalone crude extract. In SDS-PAGE with IgE immunoblotting, we identified possible antigens sized 55, 100, and 25 kDa, respectively. This is the first case of abalone-induced anaphylaxis in Korea.

Background/Aims:
Few studies have investigated terminal ileal lesions and their prognostic value in patients with ulcerative colitis (UC). We evaluated the clinical significance of these lesions as a prognostic factor in patients with UC who were in clinical remission.
Methods:
We retrospectively selected 567 of 4,066 colonoscopy reports that included positive findings from orificial observations of the terminal ileum (TI) and appendix in patients with UC. We finally recruited patients who were in clinical remission (n=204). We compared the clinical courses, including relapse and other prognostic parameters associated with UC, between the groups.
Results:
The baseline patient characteristics were not significantly different between patients with (n=69, TI+ group) and without TI lesions (n=135, TI– group), although there were more never-smokers in the TI+ group (n=57 [82.6%] in the TI+ group; n=86 [63.7%] in the TI– group; p=0.005). Of note, appendiceal orifice inflammation (AOI) was less frequently found in the TI+ group (14.5%) than in the TI– group (71.9%, p<0.001). The cumulative relapse rate was numerically higher in the TI– group, but it was not significantly different according to the Kaplan-Meier analysis (p=0.116). Multivariate Cox regression analysis also revealed advanced age at diagnosis as the most significant factor (adjusted hazard ratio, 0.964; 95% confidence interval, 0.932 to 0.998; p=0.037), but neither TI inflammation nor AOI were significantly associated with the cumulative relapse rate in patients with UC in clinical remission.
Conclusions
For patients with UC in clinical remission, neither terminal ileal lesions nor AOI had significant clinical or predictive value for future relapse.

Background/Aims:
Many patients with Crohn’s disease (CD) undergo intestinal resection during the disease course. Despite surgery, postoperative recurrence (POR) commonly occurs. Although postoperative use of tumor necrosis factor α (TNF-α) inhibitors is known to be effective in preventing POR, few studies have evaluated the effectiveness of continuing the same TNF-α inhibitors postoperatively in patients who received TNF-ɑ inhibitors before surgery.
Methods:
This retrospective observational study was performed in a single tertiary medical center. We retrospectively reviewed patients who had undergone the first intestinal resection due to CD and divided them into two groups: TNF-α inhibitor users in both the preoperative and postoperative periods, and TNF-α inhibitor users in only the preoperative period. We compared the clinical outcomes between these two groups.
Results:
In total, 45 patients who used TNF-α inhibitors preoperatively were recruited. Among them, TNF-α inhibitors were used postoperatively in 20 patients (44.4%). The baseline characteristics except age at diagnosis were similar in both groups. The rates of surgical and endoscopic recurrence were not different between the two groups, but the cumulative clinical recurrence rate was significantly lower in the postoperative TNF-α inhibitors group (log-rank p=0.003). In multivariate Cox regression analysis, postoperative TNF-α inhibitors use was significantly associated with a decreased risk of clinical recurrence (adjusted hazard ratio, 0.204; 95% confidence interval, 0.060 to 0.691; p=0.011).
Conclusions
Continuing TNF-α inhibitors postoperatively in patients who were receiving TNF-α inhibitors before surgery significantly reduced the rate of clinical recurrence. For patients with CD who received TNF-α inhibitors preoperatively, continuing their use after surgery could be recommended.

Background/Aims:
The optimal tools for monitoring Crohn’s disease (CD) are controversial. We compared radiology plus ileocolonoscopy and radiology alone in terms of prognosis prediction and evaluated the agreement between radiologic and ileocolonoscopic findings in patients with CD.
Methods:
Patients with CD who were followed up with computed tomography enterography (CTE) or magnetic resonance enterography (MRE) alone or CTE or MRE plus ileocolonoscopy were retrospectively recruited. Time to relapse was investigated to evaluate the difference in prognosis using the log-rank and Cox regression tests, and the agreement between radiologic and ileocolonoscopic findings was determined using a kappa value.
Results:
A total of 501 patients with CD in clinical remission who underwent CTE or MRE and/or ileocolonoscopy were analyzed. Of these, 372 (74.3%) patients underwent CTE or MRE alone and 129 (25.7%) patients underwent CTE or MRE plus ileocolonoscopy. The cumulative maintenance rate of clinical remission between the two groups was not significantly different (p = 0.526, log-rank test). In multivariate analysis, age <40 years (hazard ratio [HR], 2.756; 95% confidence interval [CI], 1.263 to 6.013) and a history of steroid use (HR, 2.212; 95% CI, 1.258 to 3.577) were found to independently predict an increased risk for clinical relapse in patients with CD in clinical remission. Radiologic and ileocolonoscopic findings had a moderate degree of agreement (κ = 0.401, –0.094 to 0.142). The comparison of agreement between radiologic and ileocolonoscopic findings was the highest in the anastomotic site (κ = 0.749, –0.168 to 0.377).
Conclusions
Radiology plus ileocolonoscopy was not superior to radiology alone in predicting the prognosis of CD.
