Background and Aim: Colonic diverticulosis (CD) has been reported to be associated with presence of colon neoplasms (CNs) in Western patients, since most of the associated risk factors are common between them. However, such correlation has not been fully investigated in Asian patients. In this study, the association of CNs with CD was evaluated in a multicenter investigation. Methods: We enrolled 5633 patients who underwent both colonoscopy and esophagogastroduodenoscopy due to annual follow‐up, screening for positive occult blood testing and abdominal symptoms between January 2016 and December 2017 at three institutions. The relationship between the presence of CNs and CD was investigated, and predictors for presence of CNs were determined by multivariate logistic analysis. Results: The enrolled patients consisted of 1799 (31.9%) with CD (average age 70.0 years, male 64.0%) and 3834 without CD (66.0 years, male 52.9%), with the prevalence of CNs in those groups 46.6% and 44.2%, respectively (P = 0.090). Predictors for early colon cancer were shown to be age (OR 1.02, 95% CI 1.01–1.04, P = 0.010), laxatives use (OR 1.76, 95% CI 1.17–2.64, P = 0.007), gastric neoplasms (OR 2.16, 95% CI 1.23–3.81, P = 0.008), and CD (OR 1.64, 95% CI 1.16–2.31, P = 0.005). Early colon cancer in the distal colon was most frequently detected in patients with right‐sided CD (RR 2.50, P = 0.001). Conclusion: In Japanese patients, early colon cancer was more frequently found in those with as compared to those without CD. The presence of CD may be an important indicator for an index colonoscopy examination to detect colon cancer. (Clinical‐trial‐registry: UMIN000038985). [ABSTRACT FROM AUTHOR]

Objective: Quiescent ulcerative colitis (UC) patients often have irritable bowel syndrome (IBS)-like symptoms and we recently showed that the prevalence of IBS-like symptoms in UC patients in clinical remission was significantly higher as compared to healthy control subjects. However, the prevalence of functional dyspepsia (FD)-like symptoms in quiescent UC patients remains unknown. The purpose of this study was to evaluate the prevalence of FD-like symptoms and the overlap with IBS-like symptoms in such patients. Materials and Methods: We reanalyzed the records of UC patients in remission using the subject cohort from our previous study. Clinical remission was defined as a clinical activity index (CAI) value ≤4 for at least 6 months. Diagnoses of FD- and IBS-like symptoms were evaluated by questionnaire according to the Rome III criteria. Results: One hundred seventy-two UC patients in clinical remission and 330 healthy control subjects were analyzed. Of the 172 patients, 9 (5.2%) met the criteria of FD, which was comparable with the controls (22/330, 6.7%). The prevalence rate of FD-like symptoms in UC patients with IBS-like symptoms (7/46, 15.2%) was lower as compared to that of the control subjects (6/16, 37.5%). On the other hand, a high percentage of the UC patients with FD-like symptoms also had IBS-like symptoms (7/9, 77.8%). Conclusions: Although the prevalence of FD-like symptoms in quiescent UC patients with IBS-like symptoms was low, UC patients with FD-like symptoms frequently had IBS-like symptoms.

Objective. Irritable bowel syndrome (IBS)-like symptoms are often found in ulcerative colitis (UC) patients in remission. However, the prevalence of those symptoms in UC patients with endoscopic evidence of remission shown by mucosal healing remains unknown. Material and methods. IBS diagnosis was evaluated by questionnaire results according to the Rome III criteria. Clinical remission was assessed by clinical activity index (CAI), whereas endoscopic remission was evaluated by endoscopic index (Matts grade). Results. We enrolled 172 patients in clinical remission (CAI ≤ 4), after excluding 36 for incomplete questionnaire results or nonremission findings, as well as 330 control subjects. Of the 172 UC patients, 46 (26.7%) met the Rome III criteria, which was a significantly higher rate as compared with the controls (4.8%). The prevalence rate of IBS-like symptoms in UC patients with endoscopic remission findings (Matts grade ≤2) was 25.6%, which was similar to that of those with clinical remission. When endoscopic remission was defined as Matts grade 1, the prevalence rate of IBS-like symptoms was decreased to 15.4%, although the prevalence rate remained higher than that of the control subjects. Conclusions. The prevalence of IBS-like symptoms in UC patients with clinical and endoscopic remission findings was significantly higher than that of control subjects. Furthermore, the prevalence rate in patients with complete endoscopic remission was decreased. These findings suggest that residual low-grade inflammation may influence the presence of IBS-like symptoms in UC patients in remission. [ABSTRACT FROM AUTHOR]

Rabeprazole has a faster onset of antisecretory activity than omeprazole and lansoprazole. The aim of the present study was to clarify whether there is any difference in the speed of symptom relief in patients with reflux esophagitis following the administration of these three proton pump inhibitors (PPI). Eighty-five patients with erosive reflux esophagitis were randomized to receive 8 weeks of 20 mg of omeprazole ( n = 30), 30 mg of lansoprazole ( n = 25), or 20 mg of rabeprazole ( n = 30) once a morning. Daily changes in heartburn and acid reflux symptoms in the first 7 days of administration were assessed using a six-point scale (0: none, 1: mild, 2: mild–moderate, 3: moderate, 4: moderate–severe, 5: severe). The mean heartburn score in patients administered rabeprazole decreased more rapidly than those given the other PPI. Complete heartburn remission also occurred more rapidly in patients administered rabeprazole (compared with omeprazole: P = 0.035, compared with lansoprazole: P = 0.038 by log-rank test). No differences were seen in the rate of endoscopic healing of reflux esophagitis at 8 weeks between the three treatment regimens. Rabeprazole may be more effective than omeprazole and lansoprazole for the rapid relief of heartburn symptoms in patients with reflux esophagitis. [ABSTRACT FROM AUTHOR]
