Factors Predicting Effectiveness of Eradication Therapy for -Associated Dyspepsia Symptoms.

Functional dyspepsia is distinguishable from -associated dyspepsia. However, distinguishing -associated dyspepsia from functional dyspepsia before eradication is difficult. Therefore, in the present study, we aimed to investigate whether serum pepsinogen levels before eradication are associated with the amelioration of dyspepsia after successful eradication.

Assessment of the Physical Invasiveness of Peroral Endoscopic Myotomy during the Perioperative Period Based on Changes in Energy Metabolism.

A novel treatment method for achalasia of the esophagus and related disorders is known as peroral endoscopic myotomy (POEM). This study aimed to calculate the resting energy expenditure (REE) and evaluated the degree of physical invasiveness based on metabolic changes during the perioperative period of POEM. Fifty-eight patients who underwent POEM were prospectively enrolled; REE, body weight (BW), and basal energy expenditure were measured on the day of POEM, postoperative day 1 (POD 1), and three days after POEM (POD 3).

Influence of Esophageal Endoscopic Submucosal Dissection on the Changes of Energy Metabolism during the Perioperative Period.

Esophageal endoscopic submucosal dissection (ESD) is considered to be more complex than gastric ESD. This study aimed to assess the physical invasiveness of esophageal ESD during perioperative periods by measuring resting energy expenditure (REE). The factors affecting REE that could be used to identify patients requiring perioperative management were also investigated.

Spatial distribution of live gut microbiota and bile acid metabolism in various parts of human large intestine.

Gut microbiomics is based on analysis of both live and dead cells in the stool. However, to understand the ecology of gut microbiota and their symbiotic relationships with hosts, spatial distribution of live bacteria must be examined. Here, we analyzed the live composition of luminal microbiota (LM) and mucosa-associated microbiota (MAM) in the ascending and descending colons and the rectums of 10 healthy adults and compared it with the total composition.

Esophageal achalasia with mucosal damage due to enteric-coated aspirin.

A 76-year-old man was referred to our hospital for examination and treatment of dysphagia. He has been taking enteric-coated aspirin for myocardial infarction. Esophagogastroduodenoscopy (EGD) revealed the presence of esophageal ulcers in the distal esophagus and five to six tablets of enteric-coated aspirin.

Case report of lanthanum deposition in the esophagus.

A 69-year-old woman had received hemodialysis for chronic renal failure and was taking lanthanum carbonate since 63 years of age. She presented with appetite loss and nausea. We performed esophagogastroduodenoscopy, which revealed multiple longitudinal white plaques in the esophagus.

Usefulness of serum opsonic activity measured by chemiluminescence method to assess the invasiveness of colorectal endoscopic mucosal dissection.

Endoscopic sub-mucosal dissection (ESD) is considered as a low-invasive treatment for early-stage colorectal cancer, but the degree of invasiveness has not been well investigated. The aim of this study was to evaluate the physical stress due to colorectal ESD based on changes in serum opsonic activity (SOA). SOA was examined by measuring reactive oxygen species (ROS) produced by neutrophils using lucigenin-dependent chemiluminescence (LgCL) and luminol-dependent chemiluminescence (LmCL).

Influence of gastric endoscopic submucosal dissection on serum opsonic activity measured by chemiluminescence.

This study aimed to elucidate whether changes in serum opsonic activity measured by lucigenin-dependent chemiluminescence and luminol-dependent chemiluminescence are useful for estimating physical stress during the perioperative period of gastric endoscopic submucosal dissection. Serum opsonic activity in the peripheral blood of 87 patients was examined in the morning of the day of endoscopic submucosal dissection, the next day, and at 4 days after endoscopic submucosal dissection. Peak height and area under the curve for lucigenin-dependent chemiluminescence were 106.

Estimation of perioperative invasiveness of colorectal endoscopic submucosal dissection evaluated by energy metabolism.

The aim of this study was to assess the perioperative invasiveness of endoscopic submucosal dissection for colorectal cancer quantitatively by using energy metabolism. In fifty-three patients who underwent endoscopic submucosal dissection for colorectal cancer, resting energy expenditure using an indirect calorimeter, body weight and basal energy expenditure using the Harris-Benedict equation before and after endoscopic submucosal dissection. Resting energy expenditure/body weight and resting energy expenditure/basal energy expenditure were 19.
