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.

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.

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.

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.

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.

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is a difficult procedure to perform on patients who have undergone a Billroth II gastrectomy, Whipple's operation or Roux-en-Y gastrobypass surgery. Our study was designed to evaluate the clinical usefulness of cap-assisted ERCP for beginner endoscopists in cases of surgically altered anatomy. METHODS: From April 2008 to March 2010, 16 patients with biliary diseases and who had previously undergone abdominal surgery such as Billroth II gastrectomy or Roux-en-Y operation were analyzed. A single endoscopist performed all the procedures using a cap-assisted gastroscope, after ERCP training. RESULTS: Cap-assisted ERCP was attempted in 24 sessions of 16 patients. Afferent loop intubation and selective bile duct cannulation was successfully achieved in 19 sessions (79.1%). Among the patients who had undergone a Billroth II gastrectomy, 19 out of 20 sessions were successfully conducted. Only 4 patients who had undergone a previous Roux-en-Y operation failed afferent loop intubation. Duodenal free wall perforation developed in one case. There were no cases of mortality. CONCLUSIONS: Therapeutic cap-assisted ERCP was useful in patients who had previously undergone a Billroth II gastrectomy and this may be helpful for inexperienced endoscopists.

Ectopic openings of the common bile duct into the duodenal bulb, which are associated with biliary tract disease or recurrent/refractory duodenal ulcers, are rare. We report three such cases, all of which were documented with gastroscope, and two of which were managed with endoscopic retrograde cholangiopancreatography (ERCP) via gastroscope. We suggest that ERCP can be performed with gastroscope, since it may offer a better working position in certain cases.

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.
