RESUMEN

Diet-related cardiometabolic diseases and inflammatory bowel disease, common previously in Western countries, are global problems. We hypothesized that inflammatory bowel disease is a lifestyle disease primarily mediated by the current Western diet. We report here the simultaneous onset of ulcerative colitis and autoimmune pancreatitis, a rare systemic complication of inflammatory bowel disease, 2 months after acute myocardial infarction in a patient with type 2 diabetes. A 67-year-old man with type 2 diabetes was referred to us because of newly diagnosed ulcerative colitis 2 months after acute myocardial infarction. A plant-based diet was provided during hospitalization. An abrupt deterioration in plasma glucose and hemoglobin A1c due to asymptomatic type 2 autoimmune pancreatitis was observed. Prednisolone administration under intensive insulin therapy led to the remission of both diseases. This case was an illustrative one of association between cardiometabolic diseases and inflammatory bowel diseases caused by current unhealthy diets and their shared pathogenesis.

RESUMEN

BACKGROUND/AIMS: Gastric acid secretion is suspected to be a pivotal contributor to the pathogenesis of functional dyspepsia. The present study investigates the potential association of the gastric acid secretion estimated by measuring serum pepsinogen with therapeutic responsiveness to the prokinetic drug acotiamide. METHODS: Dyspeptic patients consulting participating clinics from October 2017 to March 2019 were prospectively enrolled in the study. The dyspeptic symptoms were classified into postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). Gastric acid secretion levels were estimated by the Helicobacter pylori infection status and serum pepsinogen using established criteria and classified into hypo-, normo-, and hyper-secretion. Each patient was then administered 100 mg acotiamide thrice daily for 4 weeks, and the response rate to the treatment was evaluated using the overall treatment efficacy scale. RESULTS: Of the 86 enrolled patients, 56 (65.1%) and 26 (30.2%) were classified into PDS and EPS, respectively. The estimated gastric acid secretion was not significantly different between PDS and EPS. The response rates were 66.0% for PDS and 73.1% for EPS, showing no significant difference. While the response rates were stable, ranging from 61.0% to 75.0% regardless of the estimated gastric acid secretion level among subjects with PDF, the rates were significantly lower in hyper-secretors than in non-hyper-secretors among subjects with EPS (42.0% vs 83.0%, P = 0.046). CONCLUSION: Although acotiamide is effective for treating EPS as well as PDS overall, the efficacy is somewhat limited in EPS with gastric acid hypersecretion, with gastric acid suppressants, such as proton pump inhibitors, being more suitable.

RESUMEN

BACKGROUND: Endoscopic mucosal resection using a cap-fitted panendoscope (EMRC) and an endoscopic submucosal dissection (ESD) are increasingly performed to treat superficial esophageal carcinoma (SEC). As an endoscopic procedure appropriate for en bloc complete resection, ESD requires a much higher level of skill and experience than EMRC. METHODS: This retrospective study reviewed 127 SECs in 112 patients treated by EMRC or ESD from January 1997 to September 2009. RESULTS: For lesions 10 mm in diameter or smaller, EMRC and ESD had equivalent en bloc resection rates with tumor-free margins (en bloc + R0 resection rates). For lesions 11 mm in diameter or larger, however, the rate was significantly higher in the ESD group than in the EMRC group (p < 0.01). The mean procedure time was significantly longer in the ESD group than in the EMRC group (p < 0.01) regardless of lesion size. No significant difference was found in esophageal perforation rate between the EMRC and ESD groups. Severe esophageal stricture developed after EMRC of eight lesions (14.3%) and after ESD of six lesions (8.5%). For patients with a mucosal defect involving more than three-fourths of the esophageal circumference, the incidence of severe esophageal stricture after procedure was significantly higher in the EMRC group than in the ESD group (p < 0.05). The overall local recurrence rate was 3.1% (4/127) during an average follow-up period of 39 months (range, 8-123 months). All local recurrences were detected as superficial cancers after EMRC and then treated endoscopically. CONCLUSIONS: For lesions 10 mm in diameter or smaller, EMRC was found to be optimal. For lesions 11 mm in diameter or larger, however, ESD was superior to EMRC in efficacy as assessed by the en bloc + R0 resection rate. Furthermore, ESD was advantageous in preventing stricture formation. The operating endoscopist should carefully select EMRC or ESD according to lesion size.

RESUMEN

In the absence of a supervisor, we conducted endoscopic submucosal dissection (ESD) procedures using the needle-knife and insulation-tipped (IT) diathermic knives for 516 gastric neoplasms in 443 Japanese patients with the diseases. No significant difference was found between IT knife ESD and needle-knife ESD in en bloc resection rates with tumor-free margins (89.8% and 92.9% for IT knife ESD and needle-knife ESD, respectively) and perforation rates (2.2% and 4.6%, respectively). However, the mean procedure time was significantly (P<0.05) shorter in IT knife ESD than in needle-knife ESD (74 and 88 min, respectively) and reached a plateau after accumulating 120 cases of ESD in both procedures. We required a less number of ESD cases before being proficient at needle-knife ESD than in IT knife ESD (30 cases and 60 cases, respectively). Needle-knife ESD is recommended for physicians who intend to master ESD hereafter.
