BACKGROUND/AIMS: Endoscopic mucosal resection (EMR) of large colorectal lesions is associated with increased procedural time. The objective of this study was to evaluate the effect of double-channel gastroscope (DCG) use on the procedural time of EMRs in the rectosigmoid area. METHODS: All EMRs for sessile or flat rectosigmoid lesions > or =2 cm performed between July 2011 and September 2012 were retrospectively analyzed. RESULTS: There were 55 lesions > or =2 cm in the rectosigmoid area in 55 patients, of which 26 were removed by EMR using a DCG (DC group) and 29 by using an ordinary colonoscope or gastroscope (OS group). The mean size of the removed polyps, morphology, adverse effects, and other parameters were similar between the two groups. The mean procedural time was significantly lower in the DC group than in the OS group (24.4+/-18.3 minutes vs. 36.3+/-24.4 minutes, p=0.015). Moreover, in a subgroup of patients with polyps >40 mm, the statistical difference in the mean procedural time between the DC and OS groups was even more pronounced (33+/-21 minutes vs. 58.7+/-20.6 minutes, p=0.004). CONCLUSIONS: Our data suggest that the use of a DCG in the resection of large nonpedunculated rectosigmoid lesions significantly reduces the procedural time.

Esophageal perforation is a rare disease, which require emergent diagnosis and therapeutic procedure. In this paper, we present one case of esophageal perforation by traction of toothbrush which was swallowed during pharyngeal irritation. After the toothbrush was inserted to stomach by gastroscope, gastrostomy was performed for removal of toothbrush and the esophageal perforation was repaired by operation.

Recently the use of hydrochloric acid as a toilet disinfectant has become more common, and the risk of its ingestion is though to be increasing. We experienced a case of 67 year-old man who accidentally ingested hydrochloric acid and as a result developed a postprandial epigastric fullness end pain 3 weeks thereafter, The patient underwent an UGI series, fiberoptic gastroscope and abdominal ultrasonography and was found to have a gastric midbody stricture. A total gastreetomy and Roux-en- Y esophagojejunostomy was performed. We report this case with brief review of the literature.

BACKGROUND/AIMS: Conventional colonoscopy is limited in some patients with several causes, such as fixed angulation, extensive loop or adhesion. Therefore, small-caliber scopes are considered alternatives to unsuccessful conventional colonoscopy. The aim of this study is to evaluate the usefulness of gastroscope in patients with unsuccessful colonoscopy. METHODS: From May 2008 to April 2009, a total of 2,548 colonoscopies were performed in Wonkwang University Hospital. The gastroscope was used subsequently when conventional colonoscopy failed. RESULTS: There were 27 cases (1.06%) of unsuccessful colonoscopy. The causes of failure were assessed as fixed angulation of the sigmoid colon (59.2%, 16/27), excessive looping (14.8%, 4/27), stricture (14.8%, 4/27), sigmoid diverticulosis (7.4%, 2/27), and adhesion of transverse colon (3.7%, 1/27). The average time of intubation to cecum with the gastroscope was 7 minutes and 28 seconds (range, 2 to 20 minutes). With the gastroscope, 77.8% (21/27) were intubated to the cecum. The pain score of gastroscope was reduced, as compared with that of conventional colonoscopy (4.95 vs. 5.94, P<0.001). CONCLUSIONS: Gastroscope would be a useful alternative tool in patients with unsuccessful colonoscopy.

Crohn's disease (CD) is a chronic inflammatory bowel disease of unknown etiology. Most patients with CD will eventually develop a stricturing or penetrating complication. Colonoscopic findings may predict the clinical course in patients with CD. Moreover, since CD patients are at increased risk for developing dysplasia and colorectal cancer, surveillance colonoscopy is necessary for the detection of malignancies. We describe here a CD patient with a high-grade anorectal stricture who successfully underwent a total colon examination with an ultra-slim upper endoscope after an insertion failure with a standard colonoscope and gastroscope.

Iron overdose is one of the most common, potentially fatal intoxication in children. We rescued a 3-year-old girl who ingested about 20 iron tablets(110 mg/kg of elemental iron) with early endoscopic intervention. The stomach showed diffusc hemorrhagic gastritis with large amount of retained corrosive iron material. Removal of iron tablets was performed successfully by gastroscope with condom attached on its tip and she recovered completely without any sequelae. The severity of the endoscopic findings even in the early stage and the uneventful clinical recovery in our patient strongly support that this approach could be tried before traditional methods. We think that gastroscopy can be both diagnostic and therapeutic tool in acute drug intoxication in children, because of its safety and easy, rapid availability.

A case was experienced involving submandibular salivary gland swelling (sialoadenopathy), developing after gastroscopy in a 15-year-old female who was suffering from epigastric pain & diarrhea and a case of parotid salivary gland swelling after gastroscopy in a 25-year-old female who was suffering from dyspepsia and epigastric pain. Both patients were the first two cases among about 5,000 gastroscopic examinations of the stomach conducted by the authors. As soon as the gastroscope was withdrawn, unilateral swelling, which was neither painful nor tender, was found in the left submandibular salivary gland area. This swelling disappeared spontaneously in about few hours later.

OBJECTIVEIn some hospitals an adult colonoscope is used for colon examination in children because they do not have child colonscope equipment. This has some disadvantages and this paper reports the experience for colon examination in children with an adult gastroscope instead of an adult colonoscope.

METHODSOne hundred and three children aged from 1.3 to 14 years who required routine colon examination were randomly assigned to adult gastroscope (n=49) and adult colonoscope groups (n=54).

RESULTSThere were no significant differences in the success rate of implantation into the ileocecum between the gastroscope and colonoscope groups (93.9% vs 94.4%; P>0.05). The average time of implantation into the ileocecum in the gastroscope group was shorter than that of the colonoscope group (5.2+/-1.1 min vs 7.3+/-2.9 min; P<0.05). Seventeen patients showed implantation-related complications in the colonoscope group but only 5 patients in the gastroscope group (P<0.01).

CONCLUSIONSAn adult gastroscope appears to be safer and more feasible than an adult colonoscope for colon examination in children.
