Hybrid, High-Dose Dual and Bismuth Quadruple Therapies for First-Line Treatment of Helicobacter pylori Infection in Taiwan: A Multicenter, Open-Label, Randomized Trial.

INTRODUCTION: The study aimed to compare the efficacies and safety of 14-day hybrid therapy, 14-day high-dose dual therapy, and 10-day bismuth quadruple therapy in the first-line treatment of Helicobacter pylori infections. METHODS: In this multicenter, open-label, randomized trial, we recruited adult H. pylori -infected patients from 9 centers in Taiwan. Subjects were randomly assigned (1:1:1) to 14-day hybrid therapy, 14-day high-dose dual therapy, or 10-day bismuth quadruple therapy. Eradication status was determined by the 13 C-urea breath test. The primary outcome was the eradication rate of H. pylori assessed in the intention-to-treat population. RESULTS: Between August 1, 2018, and December 2021, 918 patients were randomly assigned in this study. The intention-to-treat eradication rates were 91.5% (280/306; 95% confidence interval [CI] 88.4%-94.6%) for 14-day hybrid therapy, 83.3% (255/306; 95% CI 87.8%-95.0%) for 14-day high-dose dual therapy, and 90.2% (276/306; 95% CI 87.8%-95.0%) for 10-day bismuth quadruple therapy. Both hybrid therapy (difference 8.2%; 95% CI 4.5%-11.9%; P = 0.002) and bismuth quadruple therapy (difference 6.9%; 95% CI 1.6%-12.2%; P = 0.012) were superior to high-dose dual therapy and were similar to one another. The frequency of adverse events was 27% (81/303) with 14-day hybrid therapy, 13% (40/305) with 14-day high-dose dual therapy, and 32% (96/303) with 10-day bismuth quadruple therapy. Patients receiving high-dose dual therapy had the fewest adverse events (both P < 0.001). DISCUSSION: Fourteen-day hybrid therapy and 10-day bismuth quadruple therapy are more effective than 14-day high-dose dual therapy in the first-line treatment of H. pylori infection in Taiwan. However, high-dose dual therapy has fewer adverse effects than hybrid bismuth quadruple therapies.

Distinct Physiological Characteristics of Isolated Laryngopharyngeal Reflux Symptoms.

BACKGROUND & AIMS: Patients with isolated laryngopharyngeal reflux symptoms (LPRS) defined as those without concomitant typical reflux symptoms (CTRS) are clinically challenging to manage due to unclear pathophysiology. We investigated esophageal physiology in patients with isolated LPRS and their response to proton-pump inhibitors (PPI) therapy. METHODS: This is a multi-center observational study conducted in referral hospitals in Taiwan. Patients with predominant LPRS, but without common non-reflux causes, underwent esophageal manometry, 24-hr ambulatory esophagopharyngeal pH testing, and Bernstein test, followed by a 12-week esomeprazole 40 mg twice-daily treatment. Participants with pathological reflux were divided into the isolated LPRS group (ie, LPRS without CTRS, n = 40) and the CTRS group (ie, LPRS with CTRS, n = 66). Participants without pathological reflux or esophagitis (n = 132) served as the nonreflux controls. RESULTS: The PPI-responsiveness was similar between the isolated LPRS group and CTRS group (63% vs 57%, P = .8), but lower in the nonreflux controls (32%, P = .005). Despite similar distal esophageal acid exposure time (P = .7) when compared to those with CTRS, the isolated LPRS group had a lower prevalence of both positive Bernstein test (P = .001) and ineffective esophageal motility disorder (P = .03), and fewer pharyngeal acid reflux episodes (P < .0001). CONCLUSIONS: Our findings indicate similar distal esophageal acid exposure and PPI-responsiveness between LPRS patients with and without CTRS. The lack of CTRS in the isolated LPRS group is likely due to esophageal acid hyposensitivity and fewer pharyngeal acid reflux episodes, thus implicating distinct pathophysiology of isolated LPRS from those with CTRS.

Duodenal major papilla morphology can affect biliary cannulation and complications during ERCP, an observational study.

BACKGROUND: We investigated whether duodenal major papilla morphology could be a risk factor for failure of selective biliary cannulation (SBC) and post endoscopic retrograde cholangiography and pancreatography (ERCP) complications. METHODS: A prospectively recorded database was reviewed retrospectively. Patients were included if they received therapeutic ERCP and had naïve major duodenal papilla. We used Haraldsson's classification for papilla morphology, as follows: Regular (Type 1), Small (Type 2), Protruding or Pendulous (Type 3) and Creased or Ridged (Type 4). Risk factors for failing SBC and post-ERCP complications were analyzed by multivariate analysis. RESULTS: A total of 286 cases were included. Age, gender, indications and therapeutic procedures were not different among the four types of papillae. The failure rates of SBC with Type 3 papilla and Type 4 papilla were 11.11% and 6.25%, respectively. In the multivariate analysis, Type 2 papilla (odd ratio 7.18, p = 0.045) and Type 3 papilla (odd ratio 7.44, p = 0.016) were associated with greater SBC failure compared with Type 1 papilla. Malignant obstruction compared to stone (odds ratio 4.45, p = 0.014) and age (odd ratio = 1.06, p = 0.010) were also risk factors for cannulation failure. Type 2 papilla was correlated with a higher rate of post-ERCP pancreatitis (20%, p = 0.020) compared to the other types of papilla However, papilla morphology was not a significant risk factor for any complications in the multivariate analysis. CONCLUSION: Small papilla and protruding or pendulous papilla are more difficult to cannulate compared to regular papilla. Small papilla is associated with a higher rate of post-ERCP pancreatitis.

Liver resection for hepatocellular carcinoma in oldest old patients.

BACKGROUND: For hepatocellular carcinoma (HCC), liver resection is a classical curative modality, despite its technical complexity. The incidence of HCC in the oldest old people (aged ≥ 85 years) is rising along with the global increase in life expectancy. Currently, no report has addressed liver resection for HCC in this aged population. PATIENTS AND METHODS: We conducted a retrospective review of 1889 patients receiving curative liver resection for newly diagnosed HCC from 1992 to 2016. At the time of operation, 1858 of them were aged < 85 years (group A), and 31 were aged ≥ 85 years (group B). Another 18 oldest old patients, whose HCC was considered resectable but were not operated on due to the patient's refusal, served as the control group (group C). The clinicopathological characteristics and early and long-term outcomes were compared between groups A and B. All associated co-morbidities of the patients were well-treated before liver resection. The overall survival (OS) rates were also compared between groups B and C. RESULT: Group B had a significantly higher incidence of associated co-morbidities and hepatitis C infection. Postoperative complication rates and 90-day mortality rates after liver resection did not differ between groups A and B (p = 0.834 and p = 1.000, respectively), though group B had a longer postoperative stay (p = 0.001). In groups A and B, the 5-year disease-free survival rates were 29.7% and 22.6% (p = 0.163), respectively, and their overall survival rates were 43.5% and 35.5% (p = 0.086). The overall survival rate of group B was significantly different from group C (35.5% vs. 0%, p = 0.001). CONCLUSION: Despite a longer postoperative recovery period, liver resection for HCC in the oldest old patients may be justified if co-morbidities are well controlled.

Risk factors and metabolic abnormality of patients with non-alcoholic fatty liver disease: Either non-obese or obese Chinese population.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) occurs not only in obese individuals but also in non-obese ones. The aim of this study was to focus on the association between NAFLD and metabolic events in a non-obese or obese Chinese population. METHODS: Data collected from subjects registered at Taichung Veterans General Hospital from January to December 2009 were analyzed. The exclusion criteria were alcoholics, chronic hepatitis B or C. Patients included in analyses were assigned to four groups according to sonography of their liver (normal or NAFLD), and body mass index (BMI) levels (non-obese if BMI < 25 kg/m2 or obese if BMI ≥ 25 kg/m2). RESULTS: There were 745, 208, 770 and 285 patients enrolled in four groups labeled non-obese normal liver (group A), non-obese NAFLD (group B), obese normal liver (group C) and obese NAFLD (group D), respectively. The highest ratio of metabolic syndrome existed in the group B (26.9%), followed by group A (11.7%), group D (10.9%) and finally the group C (5.2%). The positive association with NAFLD in non-obese individuals was significant in triglyceride (OR = 1.01; 95% CI: 1.01-1.02) and glucose (OR = 1.02; 95% CI: 1.01-1.03), while the positive association with NAFLD in obese subjects was only significant in triglyceride (OR = 1.01; 95% CI: 1.01-1.02). The positive association was most significant in all cases (adjusted OR = 2.41; 95% CI: 1.78-3.24), especially in non-obese individuals (OR = 2.81; 95% CI: 1.92-4.12). CONCLUSIONS: Non-obese NAFLD subjects displayed a higher proportion of metabolic abnormality. Hyperlipidemia and hyperglycemia had the most positive strength association with NAFLD.

Real-world practice and Expectation of Asia-Pacific physicians and patients in Helicobacter Pylori eradication (REAP-HP Survey).

OBJECTIVE: The aims of the study were: 1, to survey the most popular anti-H. pylori regimens in Asia-Pacific region and the real-world effectiveness of these regimens; and 2, to investigate the expectation gaps of eradication rate between physicians and patients. DESIGN: A questionnaire was distributed to Asia-Pacific physicians who attended the Asia-Pacific Digestive Week 2015 meeting. Reported eradication rates from the literatures were compared with real-world rates of surveyed popular regimens within the region. In addition, a questionnaire was distributed to H. pylori-infected patients in three regions of Taiwan. RESULTS: A total of 691 physicians and 539 patients participated in the survey. The top five most commonly used regimens were 7-day clarithromycin-based standard triple therapy (50.4%), 14-day clarithromycin-based standard triple therapy (31.0%), 10-day sequential therapy (6.1%), 14-day bismuth quadruple therapy (3.9%), and 14-day hybrid therapy (3.6%). All countries except for China had a significant gap between the expectation of physicians on anti-H. pylori therapy and the real-world eradication rate of most commonly adopted regimens (all P value <.05). The expectation on minimal eradication rate among patients was higher than that of physicians (91.4% vs 86.5%, P<.001). CONCLUSIONS: It is time for physicians in Asia-Pacific countries to adopt newer and more efficacious anti-H. pylori regimens to meet the Kyoto consensus recommendation and their patients' expectations.

The association of non-alcoholic fatty liver disease and metabolic syndrome in a Chinese population.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is associated with features of metabolic syndrome. The aim of this study was to investigate the association between NAFLD and metabolic syndrome in a Chinese population. METHODS: Data from subjects were retrospectively collected from 2006 to 2009. The exclusion criteria included significant consumption of alcohol and chronic hepatitis B and C. The patients were assigned to two groups according to ultrasound findings: normal group and fatty liver group. The liver function of patients was determined by assessing serum alanine aminotransferase (ALT). Metabolic syndrome was diagnosed based on the 2005 International Diabetes Federation criteria. RESULTS: A total of 7568 subjects were enrolled and 5736 (75.8%) and 1832 (24.2%) patients were assigned to the normal and fatty liver groups, respectively. The fatty liver group had significant male predominance (69.7% vs 56.0%), higher body mass index (mean, 26.67 vs 23.55 kg/m2) compared with the normal group. There were 441 (7.7%) and 377 (20.6%) cases with metabolic syndrome in the normal and fatty liver groups, respectively, with significant difference (P=0.001), and the subgroup of 385 cases with fatty liver and elevated ALT had higher prevalence (28.8%) of metabolic syndrome. The strongest association of an individual component of metabolic syndrome with NAFLD was hyperlipidemia (adjusted OR=2.55, 95% CI: 2.22-2.94). CONCLUSION: The individuals with NAFLD had a higher ratio of metabolic syndrome. Hyperlipidemia had the strongest positive association with NAFLD.

Diverticular disease and additional comorbidities associated with increased risk of dementia.

BACKGROUND AND AIM: Colonic diverticular disease may cause a chronic systemic effect, but its role in the development of dementia remains unclear. The purpose of this study was to investigate the potential increased risk for dementia in colonic diverticular disease. METHODS: We conducted a population-based cohort study using data from Taiwan's National Health Insurance Research Database. A total of 66 377 sex-matched, age-matched, and index year-matched (1:4) pairs of patients with colonic diverticular disease and 265 508 patients without colonic diverticular disease, who served as controls, were selected from all potential participants aged 20 years or older in the database. Each subject was individually tracked from 2000 to 2011 to identify incident cases of dementia. Cox proportional hazards regression was employed to calculate the hazard ratios and 95% confidence intervals for the association between colonic diverticular disease and dementia. RESULTS: There were 1057 dementia cases in the diverticular disease cohort during the follow-up period of 315 171 person-years; the overall incidence rate of dementia differed from that of the control group (3.35 vs 2.43 per 1000 person-years, P < 0.001). The adjusted hazard ratio for dementia was 1.24 (95% confidence interval 1.15-1.33) for diverticular disease patients after adjusting for age, sex, and comorbidities. CONCLUSIONS: Colonic diverticular disease may be associated with increased risk for dementia.

Risk of liver cirrhosis in patients with tuberculosis: a nationwide cohort study.

BACKGROUND: Most of the previous reports found cirrhosis patients with a high risk of subsequent tuberculosis (TB). However, data about the risk of developing liver cirrhosis in TB patients are limited. As a hepatitis endemic area, the risk of liver cirrhosis in patients with TB should be elucidated in Taiwan. METHODS: We conducted the study using Taiwan's National Health Insurance Research Database. Patients with TB (n = 9339) were identified as the TB cohort and matched with a control (n = 37 356). Each study participant was followed until diagnosis of liver cirrhosis, loss of follow-up, death, withdrawal from the insurance or until 31 December 2011. RESULTS: A cumulative incidence of liver cirrhosis in the TB cohort had a significantly higher risk for liver cirrhosis compared with the control (log-rank test, P < 0·001). The overall incidence of liver cirrhosis was significantly higher in the TB group than in controls [3·83 vs. 2·02 per 1000 person-year; crude hazard ratio (HR) = 1·88; 95% confidence interval (CI) = 1·59-2·23]. After controlling for age, gender and comorbidities, the risk was 1·79-fold (95% CI = 1·50-2·14) higher in the TB group than in the controls. Analysis by Cox proportional hazard regression revealed that TB increased the risk of cirrhosis in patients with either hepatitis B (adjusted HR = 1·91; 95% CI = 1·05-3·47) or hepatitis C (adjusted HR = 2·56; 95% CI = 1·37-4·78). CONCLUSION: An increased incidence of liver cirrhosis was observed among TB patients in Taiwan.

Statins are associated with a reduced risk of cholangiocarcinoma: a population-based case-control study.

AIMS: Cholangiocarcinoma (CCA) is the second most common primary liver cancer in the world. Due to the lack of effective treatments, the survival rate of CCA is low and it is usually considered difficult to diagnose early. To date, no effective strategies for the prevention of CCA have been developed. Statins are cholesterol-lowering agents which possess pleiotropic properties and the use of statins may reduce cancer risk. The aim of the study was to investigate the effect of statin use on the risk of CCA. METHODS: We used nationwide insurance data to perform a case-control study including 3174 CCA patients diagnosed in 2002-2011 and 3174 propensity score matched controls. Odds ratios (ORs) and 95% confidence intervals (CI) were calculated to assess the association between CCA risk and statin use by type of statin and dose. RESULTS: Patients with CCA were slightly younger than controls with mean ages of 67.4 (SD 12.3) and 68.5 (SD 13.2) years (P = 0.001), respectively, and had less users of statins (22.7 vs. 26.5%, P < 0.001). The overall adjusted OR of statin use associated CCA was 0.80 (95% CI 0.71, 0.90) and lowered for those with longer medications. The OR ranged from 0.65 to 0.77. Stronger dose-response association was seen when using lovastatin. CONCLUSIONS: Statin use is associated with reduced risk of CCA and there is a dose-response relationship between the use of statins and risk of CCA.

Responder Definition of a Patient-Reported Outcome Instrument for Laryngopharyngeal Reflux Based on the US FDA Guidance.

BACKGROUND: Different end-point measures may contribute to inconsistent therapeutic responses in relief of laryngopharyngeal reflux (LPR) symptoms. OBJECTIVES: We aimed to determine an a priori responder definition for a patient-reported outcome instrument, the Reflux Symptom Index (RSI), using an anchor-based method, to interpret individual treatment benefit in patients with LPR, on the basis of the US Food and Drug Administration guidance. METHODS: Patients with chronic laryngeal symptoms suggestive of LPR underwent twice-daily 40 mg esomeprazole treatment for 12 weeks. We used a 50% or more reduction in the primary laryngeal symptom at week 12, an empirical criterion, as an anchor to dichotomize the participants into two groups, and to establish a responder definition of the RSI score change. The optimal cutoff point of the RSI score change was determined on the basis of the maximal Youden index of the receiver operating characteristic analysis. RESULTS: The mean reduction in the RSI score was significantly greater in subjects with a 50% or more reduction in the primary laryngeal symptom than in those without (-11.0 ± 7.8 vs. -3.1 ± 8.3, P < 0.0001). A reduction of six points or more in the RSI score at week 12 was considered to be the responder definition with a sensitivity of 0.79 and a specificity of 0.70. CONCLUSIONS: We propose an a priori responder definition derived from an empirical criterion according to the Food and Drug Administration guidance: a reduction of six points or more in the RSI score at week 12. This preliminary estimate provides a clinically meaningful change at an individual level, although additional studies and validations across various languages are required.

Impact of severe oesophagogastric varices on liver resection for hepatocellular carcinoma in cirrhotic patients.

BACKGROUND: The aim of the present study was to clarify both short-term and long-term results of patients with concomitant hepatocellular carcinoma (HCC) and high-risk oesophagogastric varices (OGV). METHODS: This retrospective study identified 927 cirrhotic patients who underwent curative resection of HCC between 1995 and 2012 in single institution. Patients were separated into 3 groups (A, B, and C) according to general rules for recording endoscopic findings of oesophagogastric varices proposed in Japan in 1991. Groups A, B, and C consisted of patients without OGV (F0), patients with mild to moderate OGV (F1 to F2), and patients with high-risk OGV (F3 and/or red color sign), respectively. All patients in group C underwent prophylactic endoscopic variceal ligation/sclerotherapy. Post-operative complications, mortality, overall survival, and disease-free survival were compared among 3 groups. RESULTS: No patient had post-operative variceal bleeding. Complication rates of Clavien-Dindo grade II to V in three groups were 13.6, 14.0, and 6.9 %, respectively (P > 0.05). Operative mortality, 5-year overall survival rate, and disease-free survival rate among the 3 groups were not significantly different (P > 0.05). CONCLUSIONS: Prophylactic endoscopic variceal ligation/sclerotherapy effectively prevented from post-operative variceal bleeding in patients with high-risk OGV. Operative mortality, major morbidity, and survival of patients with high-risk OGV were similar to those of patients without OGV or those with mild OGV. Liver resection remains a feasible choice for cirrhotic patients with concomitant HCC and high-risk OGV.

Impact of Overlapping Functional Gastrointestinal Disorders on the Presentation and Quality of Life of Patients with Erosive Esophagitis and Nonerosive Reflux Disease.

OBJECTIVE: The aim of this study was to investigate the impact of overlapping functional gastrointestinal disorder (FGID) on the quality of life of patients with nonerosive reflux disease (NERD) and erosive esophagitis (EE). MATERIALS AND METHODS: Data from patients with NERD and EE were collected between January 2009 and March 2010. These cases were further stratified into the subgroups of overlapping NERD-functional dyspepsia (FD), NERD-irritable bowel syndrome (IBS), EE-FD, EE-IBS, and NERD or EE alone according to the symptoms. All patients completed the modified Chinese GERDQ and the SF-36 questionnaires. RESULTS: Of the 222 enrolled patients, 96 (43.2%) had NERD and 126 (56.8%) had EE. Overlap of FGID occurred in 43.8-45.8% of the NERD patients, and in 41.3-44.4% of EE cases. The impact of overlapping FGID on patient quality of life was greater in the patients with overlapping NERD-FD compared to those with NERD alone (mean SF-36 total scores 59 vs. 72, adjusted p = 0.025) and the cases with overlapping EE-FD compared to those with EE alone (mean SF-36 total scores 53.19 vs. 73.11, adjusted p = 0.047). There were no significant differences between the individuals with overlapping NERD/EE-IBS and those with NERD/EE alone. CONCLUSIONS: There was a high prevalence of overlapping FGID, with both FD and IBS, among the GERD patients. The individuals with overlapping GERD and FD had lower quality of life scores than those with GERD alone.

The impact of acid-suppressing drugs to the patients with chronic obstructive pulmonary disease: A nationwide, population-based, cohort study.

BACKGROUND: A high prevalence of gastroesophageal reflux disease symptoms has observed among chronic obstructive pulmonary disease (COPD) patients, and proton-pump inhibitors (PPIs) are the main medication in clinical practices. The aim of this study is to analyze the impact of PPIs to the risk of pneumonia in the cases with COPD. MATERIALS AND METHODS: This was a nationwide, population-based, cohort study using National Health Insurance Program in Taiwan. The enrolled cases were newly-diagnosed COPD, older than 30 years, between 2001 and 2005. Patients' prescriptions with PPIs and histamine receptor 2 antagonists (HR2As), >2 months, were identified. The appearance of pneumonia and mortality of these enrolled patients was recorded. Multivariate Cox's regression was used to examine the influence of acid-suppressing drugs to pneumonia on individuals with COPD. RESULTS: A total of 17,498 patients were included, of whom 109 (0.6%) and 526 (3%) cases had used PPIs and HR2As respectively. The risk of pneumonia existed when patients had used concurrent PPIs (adjusted hazard ratio [HR] = 1.76; 95% confidence interval [CI] = 1.33-2.34) or HR2As (adjusted HR = 1.25; 95% CI = 1.07-1.47). The positive association was lost in the cases over 70 years. The ratio of mortality also increased in those with PPIs or HR2As. CONCLUSION: Acid-suppressing drugs, especially PPIs, are attributed to more pneumonia happening in COPD patients compare with nonusers. The association was lost in elderly cases. Use acid-suppressing drugs should be careful about a higher possibility of pneumonia in younger individuals with COPD.

Characteristics of symptom presentation and risk factors in patients with erosive esophagitis and nonerosive reflux disease.

OBJECTIVE: The aim of this study was to investigate the effect of gender on symptom presentation and quality of life of patients with erosive esophagitis (EE) and nonerosive reflux disorder (NERD). SUBJECTS AND METHODS: Medical records from patients with gastroesophageal reflux disease (GERD) between January and December 2009 were reviewed. The patients were assigned to either the EE or the NERD group. The general demographic data, the modified Chinese GERDQ scores and the Short Form (SF)-36 life quality questionnaire scores of the two groups of patients were compared. RESULTS: Of the 261 patients, 87 (33.3%), 86 (33.0%) and 88 (33.7%) patients were classified into the EE, the NERD and the control groups, respectively. The patients in the EE group were significantly older (48.94 ± 17.38 vs. 43.34 ± 12.67 years), were predominately male (58.6 vs. 39.5%), had more frequently hiatal hernia (34.5 vs 17.4%), had a higher body weight (67.57 ± 15.13 vs. 61.06 ± 11.08 kg) and a higher body mass index (24.09 ± 4.61 vs. 22.68 ± 3.12) than those in the NERD group. The GERD-specific symptom scores and the general life quality scores of the EE and the NERD groups were similar, and both groups had lower life quality scores than the control group did. The female patients with NERD had a higher frequency of GERD symptoms and lower quality of life scores. Gender had no effect on symptom scores or life quality scores in the EE group. CONCLUSION: The GERD-specific symptom severity and general quality of life scores of the EE and the NERD patients were similar. Gender had a great influence on symptom presentation and quality of life in patients with NERD, but not in those with EE.

A miniature ultrasound probe is useful in reducing rebleeding after endoscopic cyanoacrylate injection for hemorrhagic gastric varices.

OBJECTIVE: To better assess the usefulness of miniature ultrasound probe (MUP) sonography in the evaluation of the adequacy of gastric variceal injection with cyanoacrylate to decrease the risk of post injection rebleeding. MATERIAL AND METHODS: Sixty-nine patients with bleeding gastric varices were included in this study. Endoscopic cyanoacrylate injection was performed in the acute phase for variceal hemostasis. After injection, patients (n = 34) included in the MUP group prospectively received endoscopic ultrasonography (EUS) with MUP during each scheduled endoscopic follow-up session. Patients (n = 35) in the control group who were included historically were followed up with the same interval with endoscopy only. RESULTS: Four (11.4%) patients in the control group received reinjection, and there were 10 episodes of rebleeding in 7 (20.0%) patients. Nine (26.5%) patients received reinjection due to inadequate obturation as judged by EUS. There were six episodes of rebleeding in three (8.8%) patients in the MUP group. The free-of-rebleeding rate for the MUP group was significantly higher than that for the control group (p < 0.05). The cumulative survival for the MUP group was slightly better than that for the control group but was not statistically significant. The patients' compliance in both groups was similar. The endosonographers considered the performance of MUP sonography to be convenient. CONCLUSIONS: MUP sonography is useful for the evaluation of the adequacy of tissue adhesive obturation of gastric varices that may reduce the probability of rebleeding.

Colloid Carcinoma of the Pancreas with a Series of Radiological and Pathological Studies for Diagnosis: A Case Report.

Pancreatic colloid carcinoma is an uncommon and unique malignancy possessing a significantly more favorable prognosis than that of ordinary pancreatic ductal adenocarcinoma. Accurate diagnosis of this rare entity is thus important for leading the ensuing optimal treatment. Herein we report a case of colloid carcinoma of the pancreas with a series of imaging findings and pathologic assessments. Being familiar with these radio-pathological features makes early diagnosis possible prior to operation.

Colorectal Cancer Risk in Women with Gynecologic Cancers-A Population Retrospective Cohort Study.

We conducted a retrospective cohort study to evaluate the subsequent colorectal cancer (CRC) risk for women with gynecologic malignancy using insurance claims data of Taiwan. We identified patients who survived cervical cancer (N = 25,370), endometrial cancer (N = 8149) and ovarian cancer (N = 7933) newly diagnosed from 1998 to 2010, and randomly selected comparisons (N = 165,808) without cancer, matched by age and diagnosis date. By the end of 2011, the incidence and hazard ratio (HR) of CRC were estimated. We found that CRC incidence rates were 1.26-, 2.20-, and 1.61-fold higher in women with cervical, endometrial and ovarian cancers, respectively, than in comparisons (1.09/1000 person-years). The CRC incidence increased with age. Higher adjusted HRs of CRC appeared within 3 years for women with endometrial and ovarian cancers, but not until the 4th to 7th years of follow up for cervical cancer survivals. Cancer treatments could reduce CRC risks, but not significantly. However, ovarian cancer patients receiving surgery alone had an incidence of 3.33/1000 person-years for CRC with an adjusted HR of 3.79 (95% CI 1.11-12.9) compared to patients without any treatment. In conclusion, gynecologic cancer patients are at an increased risk of developing CRC, sooner for those with endometrial or ovarian cancer than those with cervical cancer.
