Background and study aims: The Endocuff is a new colonoscopy accessory that has been designed to improve both the adenoma detection rate and endoscope tip control. Patients and methods: A total of 50 Endocuff-assisted colonoscopies were analyzed retrospectively with regard to safety, procedural success, and complications. Results: The cecal intubation rate was 98 %, and the mean intubation time was 6.0 minutes (95 % confidence interval 5.3 – 6.6 minutes). The ileal intubation rate was 76 %. In 30 % of patients, the Endocuff caused small, superficial, “scratch-like” mucosal lesions. In all other patients, no Endocuff-associated complications were observed. A total of 36 adenomas were detected in 50 patients. The adenoma detection rate was 34 %. Conclusions: Endocuff-assisted colonoscopy showed good procedural success rates in terms of cecal intubation rate and time, and a promising adenoma detection rate. Endocuff seems to improve endoscope tip control, especially during polypectomy. Endocuff may be a useful device for colorectal adenoma screening, and should be investigated in larger trials.

BACKGROUND AND STUDY AIMS: Acute pancreatitis is considered a relevant major complication following endoscopic retrograde cholangiopancreatography (ERCP); according to literature data, the incidence varies between 1.5 % and 17 %. In the present study, we aimed to identify potentially new, hitherto unknown risk factors for post-ERCP pancreatitis. PATIENTS AND METHODS: A total of 2364 ERCP procedures performed in 1275 patients during the years 2004 - 2008 were included in the study. Post-ERCP pancreatitis was defined as acute abdominal pain within 48 hours following ERCP with at least 3-fold elevated levels of serum lipase and a requirement for analgesic drugs for at least 24 hours. The severity of the pancreatitis was determined using the Imrie score. RESULTS: In our cohort study a total of 54 different patients (2.3 %) developed post-ERCP pancreatitis. In 50 of these patients (92.6 %) the pancreatitis was mild; in 54 (7.4 %) it was severe. Patients with post-ERCP pancreatitis had highly significantly lower bilirubin levels than patients who did not have post-ERCP pancreatitis ( P < 0.001). Length of hospital stay, duration of analgesics, and need for analgesic drugs were significantly higher in patients suffering from severe pancreatitis ( P ≤ 0.01). In multivariate analysis, among other, already well-described risk factors we identified intraductal ultrasonography as another risk factor for post-ERCP pancreatitis, with a hazard ratio of 2.41 ( P = 0.004). CONCLUSIONS: According to our retrospective data, intraductal ultrasonography seems to be another independent risk factor for developing post-ERCP pancreatitis, which needs to be further elucidated in prospective studies.
