ABSTRACT
OBJECTIVE: Right-sided type colonic diverticulosis has been predominant in Japan, in contrast to European counties where the left-sided type is predominant. Considering the recent change in the dietary habits of Japanese people to a more Western diet in urban areas of Japan, the features of colonic diverticulosis may also change to reflect a more Western type. Therefore, we attempted to clarify the current situation. METHODS: A total of 435 consecutive outpatients who agreed to a barium enema and complete examination were enrolled in this study. RESULTS: 113 patients (26.0%) revealed colon diverticulosis; 50.4% of the patients had more than ten diverticula. The percentage of man with ten or more diverticula (67.4%) was significantly higher than that of women patients (40.0%, p<0.01). Among the 88 patients who had four or more diverticula, 39 patients (44.3%) were right-side dominant, 27 (30.7%) left-side dominant and 22 (25.0%) were both-sides. Thirteen (68.4%) of the 19 patients who had more than 30 diverticula were left-side dominant. CONCLUSION: The clinical features of colon diverticulosis in the patients living in Yokohama may be changing to reflect a more Western type, in particular decreased right-side dominance, increases in the left-side and both-sides dominant patients, and the emergence of patients with crowded diverticula in the left-side colon was observed.

AIM: To evaluate the effectiveness of barium impaction therapy for patients with colonic diverticular bleeding. METHODS: We reviewed the clinical charts of patients in whom therapeutic barium enema was performed for the control of diverticular bleeding between August 2010 and March 2012 at Yokohama Rosai Hospital. Twenty patients were included in the review, consisting of 14 men and 6 women. The median age of the patients was 73.5 years. The duration of the follow-up period ranged from 1 to 19 mo (median: 9.8 mo). Among the 20 patients were 11 patients who required the procedure for re-bleeding during hospitalization, 6 patients who required it for re-bleeding that developed after the patient left the hospital, and 3 patients who required the procedure for the prevention of re-bleeding. Barium (concentration: 150 w%/v%) was administered per the rectum, and the leading edge of the contrast medium was followed up to the cecum by fluoroscopy. After confirmation that the ascending colon and cecum were filled with barium, the enema tube was withdrawn, and the patient's position was changed every 20 min for 3 h. RESULTS: Twelve patients remained free of re-bleeding during the follow-up period (range: 1-19 mo) after the therapeutic barium enema, including 9 men and 3 women with a median age of 72.0 years. Re-bleeding occurred in 8 patients including 5 men and 3 women with a median age of 68.5 years: 4 developed early re-bleeding, defined as re-bleeding that occurs within one week after the procedure, and the remaining 4 developed late re-bleeding. The DFI (disease-free interval) decreased 0.4 for 12 mo. Only one patient developed a complication from therapeutic barium enema (colonic perforation). CONCLUSION: Therapeutic barium enema is effective for the control of diverticular hemorrhage in cases where the active bleeding site cannot be identified by colonoscopy.

BACKGROUND/AIMS: Ideally, medications for the treatment of acid-related diseases should have a rapid onset of action to promote hemostasis and the resolution of symptoms. The aim of our study was to investigate the inhibitory effects on gastric acid secretion of a single oral administration of lafutidine alone or combined with peppermint oil. METHODOLOGY: Ten Helicobacter pylori-negative male subjects participated in this randomized, two-way crossover study. Intragastric pH was monitored continuously for 4 hours after a single oral administration of lafutidine (10 mg) or the administration of lafutidine (10 mg) with peppermint oil (0.64 mL). Each administration was separated by a 7-day washout period. RESULTS: No significant difference in the average pH was observed during the 4-hour period after the combined administration of lafutidine and peppermint oil and after the administration of lafutidine alone (median gastric pH: 5.09 versus 5.29; p = 0.3122). CONCLUSIONS: In H. pylori-negative healthy male subjects, an oral dose of lafutidine combined with peppermint oil did not increase the intragastric pH faster than lafutidine alone.

BACKGROUND/AIMS: Non-alcoholic fatty liver disease (NAFLD) is a hepatic manifestation of metabolic syndrome that is closely associated with multiple factors such as obesity, hyperlipidemia, type 2 diabetes mellitus and hypertension, making it difficult to treat NAFLD effectively using any monotherapy available to date. In this study, we propose a novel combination therapy for NAFLD comprising ezetimibe (EZ), a cholesterol absorption inhibitor, and acarbose (AC), an alpha-glucosidase inhibitor. METHODS: C57BL/6J mice were divided into five treatment groups as follows: basal diet (BD), high-fat diet (HFD) only, HFD with EZ (5mg/kg/day), HFD with AC (100mg/kg/day), and HFD with both EZ and AC for 24 weeks. RESULTS: Long-term combination therapy with EZ and AC significantly reduced steatosis, inflammation and fibrosis in the liver, compared with long-term monotherapy with either drug, in an HFD-induced NAFLD mouse model; the combination therapy also significantly increased the expression of microsomal triglyceride transfer protein (MTP) and peroxisome proliferators-activated receptor-alpha1 (PPAR-alpha1) in the liver, compared with either monotherapy, which may have led to the improvement in lipid metabolic disorder seen in this model. CONCLUSIONS: Combination therapy with EZ and AC for 24 weeks improved the histopathological findings in a mouse model of NAFLD.

BACKGROUND/AIMS: Coffee is one of the most popular beverages worldwide, however, few studies have examined the effects of coffee on the gastrointestinal system. The aim of this study was to determine whether there was a correlation between coffee intake and gastric emptying using a novel non-invasive technique for measuring gastric emptying with a continuous real time 13C breath test (BreathID system: Oridion, Israel). METHODOLOGY: Six healthy male volunteers participated in this randomized, two-way crossover study. The subjects were randomly assigned to receive a test meal (200 kcal per 200 mL) plus postprandial 190 mL black coffee or the test meal alone after fasting overnight. A 13C-acetic acid breath test was continuously performed using the BreathID system, which monitors gastric emptying, for 4 hours after the administration of the test meal. Using Oridion Research Software (beta version), the time for emptying of 50% of the labeled meals (T 1/2) and the analog to the scintigraphy lag time for 10% emptying of the labeled meal (T lag) were calculated. The parameters between two occasions were compared using the Wilcoxon signed-rank test. RESULTS: After coffee intake the T 1/2 and T lag constant were significantly decreased. CONCLUSIONS: The decrease in the T 1/2 and T lag suggests the acceleration of gastric emptying. This study showed that postprandial coffee intake enhances gastric emptying, suggesting the potential use of coffee in clinical settings for patients with functional gastrointestinal disorders.

INTRODUCTION: Penetration of the colon to the posterior uterine wall secondary to diverticulitis is unusual, with diagnostic methods not yet established. Non-invasive imaging, such as computed tomography and magnetic resonance imaging may help to establish a proper diagnosis, but confirmation may be reached only after surgical exploration. CASE PRESENTATION: We report the case of a 78-year-old Japanese woman who presented with a low grade fever and mild diarrhea which occurred two or three times a week. Computed tomography and magnetic resonance imaging demonstrated a capsular lesion including an air structure with a diameter of 5 cm, between the posterior aspect of the uterine body and the sigmoid colon. A gastrograffin enema and colonoscopy demonstrated a giant diverticulum of the sigmoid colon with no evidence of malignancy. These data confirmed the diagnosis of diverticulitis complicated by a giant diverticulum. Because of a relapsing fever after therapy with antibiotics, the patient had en bloc surgical treatment of the uterus, fallopian tubes, ovaries and sigmoid colon, the organs involved in the diverticulitis, followed by an uneventful recovery. CONCLUSION: This is a rare case report of penetration of the sigmoid colon to the posterior uterine wall secondary to diverticulitis.
ABSTRACT
BACKGROUND: The aim of this study was to determine whether there was a correlation between peppermint oil and gastric emptying by using a novel noninvasive technique for measuring gastric emptying with a continuous real-time (13)C breath test (BreathID system, Oridion, Israel). METHODS: Ten healthy male volunteers participated in this randomized, two-way crossover study. The subjects were randomly assigned to receive a test meal (200 kcal per 200 ml) containing 0.64 ml of peppermint oil or the test meal alone, after fasting overnight. A (13)C-acetic acid breath test was continuously performed with the BreathID system, which monitors gastric emptying, for 4 h after the administration of the test meal. Using Oridion Research Software (beta version), the time for emptying of 50% of the labeled meals (T 1/2), the analog to the scintigraphy lag time for 10% emptying of the labeled meal (T lag), the gastric emptying coefficient (GEC), and the regression-estimated constants (beta and kappa) were calculated. The parameters between two occasions were compared using the Wilcoxon signed-rank test. RESULTS: After peppermint oil intake, the T lag and beta constant were significantly decreased. No significant differences in T 1/2, GEC, or kappa were observed between the two occasions. CONCLUSIONS: The decrease in the T lag and beta constant suggests acceleration of gastric emptying during the early phase. This study showed that peppermint oil enhances gastric emptying, suggesting the potential use of peppermint oil in clinical settings for patients with functional gastrointestinal disorders.
