- BACKGROUND AND STUDY AIMS: This study tested the diagnostic value of high-resolution endoscopy for the recognition of subtle diagnostic esophageal mucosal changes in nonerosive reflux disease. PATIENTS AND METHODS: Ten control subjects and eleven patients with nonerosive reflux disease confirmed by a validated questionnaire, standard endoscopy, and 24-hour pH-metry participated in the study. Still images were collected by high-resolution endoscopes from the distal esophagus in a standardized manner, incorporating iodine staining. Assessments were repeated in the patients with reflux disease after 4 weeks of esomeprazole therapy. Interobserver variability in the recognition of the proposed criteria was initially evaluated by 27 endoscopists using an Internet-based process. After optimisation of image quality the evaluation was repeated face-to-face with six expert endoscopists. RESULTS: No criterion was identified in either assessment that was sufficiently sensitive and specific to patients with reflux disease to be clinically useful. The kappa value, used to assess interobserver variation, was acceptably high only for invisibility of palisade vessels (0.59). Triangular indentations, apical mucosal breaks, and pinpoint blood vessels at the squamocolumnar junction were identified more frequently in the patients with reflux disease ( P < 0.05). These changes and the invisibility of the palisade vessels were significantly less prevalent in reflux patients after therapy ( P < 0.01). CONCLUSIONS: Though some distal esophageal mucosal appearances observed with the high-resolution endoscope appeared to be related to nonerosive esophageal mucosal injury, none of these changes proved to be sufficiently sensitive and specific to justify their use as a diagnostic criterion for nonerosive reflux disease.

- Background and Study Aims: Sedation and monitoring practice during colonoscopy varies between centers and over time. Knowledge of current practice is needed to ensure quality of care and help focus future research. The objective of this study was to examine sedation and monitoring practice in endoscopy centers internationally. Patients and Methods: This observational study included consecutive patients referred for colonoscopy at 21 centers in 11 countries. Endoscopists reported sedation and monitoring practice, using a standard questionnaire for each patient. Results: 6004 patients were included in this study, of whom 53 % received conscious/moderate sedation during colonoscopy, 30 % received deep sedation, and 17 % received no sedation. Sedation agents most commonly used were midazolam (47 %) and opioids (33 %). Pulse oximetry was done during colonoscopy in 77 % of patients, blood pressure monitoring in 34 %, and electrocardiography in 24 %. Pulse oximetry was most commonly used for moderately sedated patients, while blood pressure monitoring and electrocardiography were used predominantly for deeply sedated patients. Sedation and monitoring use ranged from 0 % to 100 % between centers. Oxygen desaturation (≤ 85 %) occurred in 5 % of patients, of whom 80 % were moderately sedated. On average, three staff members were involved in procedures. An anesthesiologist was present during 27 % of colonoscopies, and during 85 % of colonoscopies using deep sedation. Conclusions: Internationally, sedation and monitoring practice during colonoscopy varied widely. Moderate sedation was the most common sedation method used and electronic monitoring was used in three-quarters of patients. Deep sedation tended to be more resource-intensive, implying a greater use of staff and monitoring.

Obstructive jaundice due to isolated tuberculosis of the pancreas: endoscopic treatment instead of surgery?

- The optimal treatment for relieving biliary obstruction due to isolated pancreatic tuberculosis has not so far been defined, and most previously reported patients were treated surgically. We describe a 17-year-old, immunocompetent girl who was admitted with obstructive jaundice caused by a tuberculous mass in the head of the pancreas. Antituberculous therapy alone failed to alleviate the jaundice, and she was therefore treated by stent insertion and, subsequently, balloon dilation of the common bile duct stricture. At follow-up 5 years later, magnetic resonance cholangiopancreatography showed no evidence of stricture in the common bile duct.

- Background and study aim: Small-bowel tumors account for 1%-3% of all gastrointestinal neoplasms. Recent studies with video capsule endoscopy (VCE) suggest that the frequency of these tumors may be substantially higher than previously reported. The aim of the study was to evaluate the frequency, clinical presentation, diagnostic/therapeutic work-up, and endoscopic appearance of small-bowel tumors in a large population of patients undergoing VCE. Patients and methods: Identification by a questionnaire of patients with VCE findings suggesting small-bowel tumors and histological confirmation of the neoplasm seen in 29 centers of 10 European Countries. Results: Of 5129 patients undergoing VCE, 124 (2.4%) had small-bowel tumors (112 primary, 12 metastatic). Among these patients, indications for VCE were: obscure gastrointestinal bleeding (108 patients), abdominal pain (9), search for primary neoplasm (6), diarrhea with malabsorption (1). The main primary small-bowel tumor type was gastrointestinal stromal tumor (GIST) (32%) followed by adenocarcinoma (20%) and carcinoid (15%); 66% of secondary small-bowel tumors were melanomas. Of the tumors, 80.6% were identified solely on the basis of VCE findings. 55 patients underwent WE as the third procedure after negative bidirectional endoscopy. The lesions were single in 89.5 % of cases, and multiple in 10.5%. Retention of the capsule occurred in 9.8% of patients with small-bowel tumors. After VICE, 54/124 patients underwent 57 other examinations before treatment; in these patients enteroscopy, when performed, showed a high diagnostic yield. Treatment was surgery in 95% of cases. Conclusions: Our data suggest that VCE detects small-bowel tumors in a small proportion of patients undergoing this examination, but the early use of this tool can shorten the diagnostic workup and influence the subsequent management of these patients.
