1668 patients (male: 1,099, female: 569) experienced the epigastric pain, dyspepsia,nausea, weight loss, digestive bleeding received the endoscopic diagnosis for inflamatory and ulceration, histological diagnosis and detection of H.pylori. The results have shown that the rate of possitive H.pylory infection in men was higher than this in women (60.28% compared with 51.80%). The test’s sensitivity and specificity were 93-98% and 98%, respectively.

BACKGROUND/AIMS: Small-caliber esophagogastroduodenoscopy (scEGD) was developed to facilitate unsedated EGD, and has many advantages over sedated EGD in terms of costs and complications. This study compared the feasibility and tolerance of scEGD with unsedated conventional EGD (cEGD), and examined the effect of the endoscopic diameter on the patients' tolerance. METHODS: A total of 114 patients who were referred for a diagnostic EGD was randomly allocated to undergo either scEGD (GIF XP260, Olympus, diameter 6.5 mm; n=57) or cEGD (GIF XQ240, Olympus, diameter 9.0 mm; n=57). After EGD, the patients and endoscopists completed questionnaires on the level of discomfort, satisfaction and acceptance of the examination. RESULTS: Patients in the scEGD group reported significantly less discomfort (choking, pain and nausea) and more overall satisfaction than those in the cEGD group. Patients in the scEGD group were more willing to choose the same procedure again if medically indicated. According to multivariate analysis, the ultrathin endoscopic diameter itself was positively associated with the increased patients' satisfaction (odds ratio 3.07, p=0.003). CONCLUSIONS: scEGD has comparable feasibility and accuracy but is more tolerable than cEGD. scEGD may have a role in clinical practice by minimizing the level of discomfort during unsedated EGD.

Bezoars are retained masses of ingested materials accumulating within the gastrointestinal track. While gastric bezoars are often observed, duodenal bezoars are rarely reported. A 77-year-old man who had frequently consumed persimmons and had never undergone gastric surgery had symptoms of epigastric pain and early satiety for 10 days. Esophagogastroduodenoscopy showed many diospyrobezoars in a severely distended duodenal bulb, otherwise known as megaduodenum. The patient's treatment consisted of repeated endoscopic removal of the bezoars by using a retrieval net.

A composite glandular/exocrine-endocrine carcinoma of the gastrointestinal tract is characterized by the co-existence of two adjacent, but histologically-distinct tumors in an organ. Composite glandular/exocrine-endocrine carcinomas are a special type of tumor comprised of common adenocarcinomas and neuroendocrine components that account for at least one-third of the entire tumor area. Composite tumors have been reported in a range of organs, but are relatively rare in the stomach. We report a case of a composite neuroendocrine carcinoma with an adenocarcinoma of the stomach (mixed exocrine-endocrine carcinoma), which was misdiagnosed as a giant submucosal tumor preoperatively based on esophagogastroduodenoscopy and a contrast-enhanced axial computed tomographic scan.

OBJECTIVETo give a conceptual description of natural orifice translumenal endoscopic surgery (NOTES), review the early efforts in the NOTES field, and discuss its challenges and limitations.

DATA SOURCESThe data were retrieved mainly from publications listed in MEDLINE, PubMed and China Wanfang Database from 2005 to 2009. The search term was "NOTES".

STUDY SELECTIONThe articles involved in the "NOTES" study were selected and the review articles were excluded from the comparison.

RESULTSA marked increase in quantity in articles was shown each year for NOTES studies from 2006 to 2009. Animal experiments with "NOTES" have been carried out in China from 2007, and two independent "NOTES" procedures on humans were reported in 2009.

CONCLUSIONAlthough still in its infancy, the "NOTES" procedure is promising as another type of minimally invasive surgery and favorable alternative to current interventions.
