There are many reports about causes of corrosive agents such as acids and alkaline and occasionally hot food in either liquid or solid forms as causes of upper gastrointestinal mucosal injury. However, there have been no reports on bowel preparation solutions as a cause of upper gastrointestinal injury. We describe a case of bowel preparation solution (PICOLIGHT powder) induced thermal injury of the gastric mucosa with a review of the literature.

Taiki is a kind of fundamental vital energy filling the upper aspect of the body, and it can fall because of stress, heavy labor, diarrhea, excessive intake of drugs for regulating the flow of vital energy, or extreme deficiency in vital energy.We report the case of a 39 year old female patient who complained of dyspnea, psychic enervation, and other symptoms of falling taiki from the upper aspect of the body, caused by taking a cathartic drug (mashiningan) for constipation, while being treated for agitation and emotional incontinence. Shokanto improved this state of falling taiki from the upper aspect of the body.

BACKGROUND/AIMS: There are no established guidelines for bowel preparation formulation for bowel cleansing, nor is there an optimal method of dealing with inadequate bowel cleansing. This study investigated bowel preparation formulation preferences and responses to bowel preparation situations using surveys. METHODS: The study surveyed 221 Korean lower gastrointestinal endoscopists from January to March 2015 and assessed their responses. RESULTS: The analysis indicated that 2-L polyethylene glycol (PEG) plus ascorbic acid (Asc) was the preferred method (76.5%) and most responders expressed satisfaction with the formulation in both potency and safety. To address poor bowel preparation on the day of colonoscopy, the majority of physicians chose to order ingestion of additional preparations and proceed with the colonoscopy as scheduled (56.6%). In addition, concerns about renal safety and electrolyte stability were raised regarding oral sodium phosphate. CONCLUSIONS: This study found that 2-L PEG+Asc was preferred for potency and safety, and that Korean endoscopists preferred to proceed with colonoscopy in poor bowel preparation situations rather than choose an alternate diagnostic modality.

For improved examination of video capsule endoscopy (VCE) and device-assisted enteroscopy (DAE), bowel preparation is an essential issue. Multiple factors like air bubbles, food material in the small bowel, and gastric and small bowel transit time affect the small bowel visualization quality (SBVQ), diagnostic yield (DY) and cecal completion rate (CR). Bowel preparation with polyethylene glycol (PEG) solution enhances SBVQ and DY, but it has no effect on CR. Bowel preparation with PEG solution 2 L is similar to PEG 4 L in SBVQ, DY, and CR. Bowel preparation with fasting or PEG solution combined with anti-foaming agents like simethicone enhance SBVQ, but it has no effect on CR. Bowel preparation with prokinetics is not commonly recommended. Optimal timing for purgative bowel preparation has yet to be established. However, the studies regarding bowel preparation for DAE are not sufficient. European Society of Gastrointestinal Endoscopy (ESGE) recommends 8–12 hours fasting from solid food and 4–6 hours fasting from liquids prior to the antegrade DAE. For retrograde DAE, colonoscopy preparation regimen is recommended. This article reviews the literature and ESGE, 2013 Korean published guidelines regarding bowel preparation for VCE and DAE, following suggestion for optimal bowel preparation for VCE and balloon enteroscopy.

BACKGROUND/AIMS: Adequate bowel preparation is essential for full visualization of colonic mucosa because detection of small polyps and neoplasms depends on the quality of bowel cleansing. The aims of this study were to compare the efficacy, tolerability of preparation and side effect between two groups: clear-liquid diet with polyethylene glycol (PEG) solution versus no diet restriction with PEG solution. METHODS: This was a randomized single-blind prospective study. A total of 330 patients were randomly assigned to receive either 2 L PEG solution with a clear-liquid diet on the day before colonoscopy and another 2 L PEG solution on the day of the procedure (group 1) or 2 L PEG solution with a general diet on the day before colonoscopy and another 2 L PEG solution on the day of the procedure (group 2). RESULTS: 162 patients were assigned to group 1 and 168 patients to group 2. The satisfactory quality of bowel preparation was not significantly different between the two groups (80.2%, 78.6%, P=0.707). Patient's compliance of the clear-liquid diet in group 1 was 50%. The satisfactory quality of bowel preparation was weakly better when the clear-liquid diet was given 2 or 3 times a day (group 1A) than 0 or once a day (group 1B) (74.1%, 86.4%, P=0.048). The tolerability of the PEG solution and side effects of preparation were not significantly different in the two groups (P=0.573, 0.686). CONCLUSIONS: Bowel preparation with no diet restriction and split-dose PEG solution was similar to preparation with a clear-liquid diet in efficacy, tolerability and side effect. Therefore, the use of the clear-liquid diet protocol should improve patient's compliance.

Rhubarb is well-known for its cathartic effect, and this cathartic effect, which is closely correlated with "whter" of traditional Chinese medicine (TCM), is brought into play in colon. Recent researches about the relation between formation and effects have identified that the anthraquinone glycosides with 1,8-dio-hydroxy and without hydroxyl in the 2, 3, 6, 7 location, such as emodin, rhein, chrysophanol, et al, can bring about fairly obvious effects of "Watery Diarrhea". Aquaporins (AQPs) are expressed abundantly in colonic epithelial cells, and the abnormal expression of AQPs can lead to the less absorption of water in colon and/or the more secretion of intestinal juice, which suggest that AQPs might be one kind of the effector molecules, which some drugs playing pharmacologic actions in colon depend on. This assumption provides a novel field of vision. Is this "Watery Diarrhea" effect induced by rhubarb concerned with the location alteration or the expression change of AQPs. We deduce that the regulative effects of AQPs by rhubarb in colon might provide a new pharmacologic explation about the cathartic effect through the exploration of TCM and Chinese herbal drugs, with TCM theory and the analysis of data about efficiency and pharmacologic researches of rhubarb and the researches of AQPs. This deduction might be used to reveal why rhubarb can bring about multi-efficiency.

OBJECTIVETo investigate the value of urgent colonoscopy in the diagnosis of severe acute lower gastrointestinal bleeding and the optimal bowel preparation before examination.

METHODSThe clinical data were collected from 188 patients undergoing wither urgent or elective colonoscopy for severe acute lower gastrointestinal bleeding in Nanfang Hospital. Univariate analysis was used to assess the effect of the timing of colonoscopy on the diagnostic rate of hemorrhage, and a multivariate model which stratified bowel cleanliness was used to analyze the impact of bowel cleanliness on the diagnostic rate of urgent colonoscopy.

RESULTSOf the 188 patients, 118 underwent urgent colonoscopy and 70 underwent elective colonoscopy examinations. The diagnostic rates were comparable between the two groups (44.1% vs 41.4%, P=0.724), but urgent colonoscopy resulted in a significantly higher diagnostic rate for identifying the bleeding source (32.2% vs 18.6%, P=0.041). The proportion of the patients taking oral laxatives was significantly lower in urgent colonoscopy group (P<0.001). Oral laxatives versus enema resulted in good, moderate, and poor bowel cleanliness in 63.6% vs 13.5%, 28.6% vs 24.3%, and 7.8% vs 62.2% of the patients (P<0.001). Univariate analysis indicated that good bowel cleanliness was associated with a significantly higher diagnostic rate of colonoscopy than poor bowel cleanliness (P=0.012). Multivariate analysis showed that with good bowel cleanliness, urgent colonoscopy yielded a significantly higher diagnostic rate than elective colonoscopy (P=0.030); subgroup analyses suggested that good bowel cleanliness improved the diagnostic rate of urgent colonoscopy as compared with poor bowel cleanliness (P=0.015).

CONCLUSIONIn patients with good bowel cleanliness, urgent colonoscopy yields a higher diagnostic rate than elective colonoscopy for severe acute lower gastrointestinal bleeding. Poor bowel cleanliness resulting from bowel preparation by enema significantly lowers the diagnostic performance of urgent colonoscopy. Oral laxatives are recommended over enemas for bowel preparation before urgent colonoscopy when the patients have stable hemodynamics.

PURPOSE: The purpose of this study was to evaluate the effect of a constipation reduction program for inpatients. METHOD: Subjects were selected in one medical ward of C University Hospital from May, 2001 to November, 2001. Twenty-nine subjects were assigned to an experimental group and 32 subjects to a control group. Data related to the frequency of defecation and to the length and amount of laxative drugs used was collected by a medical record review and data on the degree of constipation was obtained by a self-report using a constipation assessment scale. RESULT: More than 90% of the subjects admitted in the department of neurology and one third of total subjects presented with activity limitation and about one fourth of the subjects were fed with a nasogastric tube. There was a significant difference in the degree of constipation, frequency of defecation, and the length and amount of laxative drug use between the two groups. CONCLUSION: This program is effective in inpatient's constipation reduction. Further studies need to apply this program in various clinical environments and properly use this program in different clinical settings.
