ABSTRACT
BACKGROUND/AIMS: The aims of this study were to compare the bowel-cleansing efficacy, patient affinity for the preparation solution, and mucosal injury between a split dose of poly-ethylene glycol (SD-PEG) and low-volume PEG plus ascorbic acid (LV-PEG+Asc) in outpatient scheduled colonoscopies. METHODS: Of the 319 patients, 160 were enrolled for SD-PEG, and 159 for LV-PEG+Asc. The bowel-cleansing efficacy was rated according to the Ottawa bowel preparation scale. Patient affinity for the preparation solution was assessed using a questionnaire. All mucosal injuries observed during colonoscopy were biopsied and histopathologically reviewed. RESULTS: There was no significant difference in bowel cleansing between the groups. The LV-PEG+Asc group reported better patient acceptance and preference. There were no significant differences in the incidence or characteristics of the mucosal injuries between the two groups. CONCLUSIONS: Compared with SD-PEG, LV-PEG+Asc exhibited equivalent bowel-cleansing efficacy and resulted in improved patient acceptance and preference. There was no significant difference in mucosal injury between SD-PEG and LV-PEG+Asc. Thus, the LV-PEG+Asc preparation could be used more effectively and easily for routine colonoscopies without risking significant mucosal injury.

Clostridium difficile (C. difficile) is a cytotoxin-producing anaerobic gram-positive rod that is responsible for pseudomembranous colitis (PMC). The incidence of C. difficile is increasing in ulcerative colitis (UC) and inflammatory bowel disease patients and is associated with a more severe course, a longer hospital stay, higher financial costs, a greater likelihood of colectomy, and high mortality. PMC may occur anywhere along the intestinal tract, but it is often found in the distal colon. PMC involving the proximal colon with rectosigmoid sparing is rarely reported in patients with UC. We describe the case of a 35-year-old woman in remission from UC who presented with frequent diarrhea and abdominal pain. She was treated with ciprofloxacin for infectious enterocolitis at a local hospital; however, her symptoms did not improve. A colonoscopy revealed yellow-white plaques with edematous, erythematous from the proximal ascending colon to the cecum, and feces positive for C. difficile toxin. She was treated with metronidazole (500 mg, three times a day) for two weeks, and improved rapidly. Physicians should carefully examine the entire colon via colonoscopy, and perform stool exams for C. difficile in patients with UC who have been treated with antibiotics and in those who develop prolonged diarrhea despite medical treatment.

Copper sulfate ingestion is a rare cause of corrosive gastrointestinal injury in the Republic of Korea. In developing countries, copper sulfate is chiefly used for agricultural purposes as a pesticide and in the leather industry. It is also used in school science classes in the form of bright blue crystals. Copper sulfate is a powerful oxidizing agent that is corrosive to mucous membranes. Concentrated solutions are acidic, with a pH of 4. We report a case of corrosive gastritis and esophagitis due to accidental copper sulfate ingestion in a 12-year-old boy.

Eosinophilic gastroenteritis is an uncommon disease characterized by eosinophilic infiltration in the bowel wall and presents various symptoms depending on the affected site and bowel layer. Pseudomembranous colitis is an antibiotic-associated infection caused by abnormal overgrowth of the toxin-producing Clostridium difficile in the large bowel. A 16-year-old boy was admitted with abdominal pain for 6 days. On admission, we performed an endoscopy and diagnosed gastroduodenitis. Then, we prescribed gastritis medication but he still presented with diffuse abdominal pain and fever above 38.0degrees C after admission. We considered infectious enterocolitis, so we prescribed an antibiotic. The next day, he presented with bloody diarrhea. A diagnosis of pseudomembranous colitis was confirmed by a colonoscopic examination with a biopsy. We also obtained a diagnosis of eosinophilic gastroenteritis through a histological diagnosis. This is the first case of the simultaneous occurrence of eosinophilic gastroenteritis and pseudomembranous colitis in the Korean medical literature. We report this case with a brief review of the literature.
