Pancreatitis is the most common complication of therapeutic endoscopic retrograde cholangiopancreatography (ERCP), and many pharmacoprophylactic approaches have been suggested, though not without ...controversy. The aim was to investigate the impact of combined therapy with diclofenac plus somatostatin on reducing the frequency and severity of post-ERCP pancreatitis (PEP).
A prospective, double-blind, placebo-controlled trial was conducted in two tertiary referral centers, with 540 eligible patients randomized to receive either combined therapy with diclofenac 100 mg rectally 30 to 60 minutes before ERCP plus somatostatin 0.25 mg/h for 6 hours (group A), or a placebo suppository identical in appearance to the diclofenac along with saline solution (group B). Patients were clinically evaluated and serum amylase levels were determined before ERCP and at 6 and 24 hours post-procedure. Standardized criteria were used to diagnose and grade the severity of PEP. Adverse events were recorded prospectively.
There were no statistical differences between the groups regarding demographic data, ERCP findings, and procedure risk factors for PEP. The overall incidence of acute pancreatitis was 7.2 %. The PEP rate was significantly lower in the patients who received the combination therapy than in controls (4.7 % vs. 10.4 %, P = 0.015). Previous history of acute pancreatitis (P = 0.001), pancreatic opacification of first-class branches and beyond (P = 0.008), and absence of pharmacoprophylaxis (P = 0.023) were identified as independent risk factors for PEP in multivariate analysis.
Although combined prophylactic therapy with diclofenac plus somatostatin was promising in reducing frequency of PEP, further comparative large-scale studies are needed to confirm our findings before definitive conclusions can be drawn.
The aim of this observational prospective study was to evaluate the safety of outpatient therapeutic endoscopic retrograde cholangiopancreatography (ERCP) in a very elderly cohort.
A total of 600 ...patients were included in the study between June 2006 and June 2009. All underwent first therapeutic ERCP and were scheduled to be discharged on the same day following a postprocedure observation period of 6 hours. Of the 600 patients, 123 patients (group A) were re-admitted due to postprocedure complications that presented during the observation period, and 477 patients (group B) were discharged on the same day. Concomitant diseases, details of ERCP procedures, complications, and outcomes were all evaluated. The accuracy of the 6-hour postprocedure observation period, clinical criteria in predicting those patients aged 80 years and older in whom all therapeutic ERCP can be performed on an outpatient basis, and costs saved were all assessed.
There was a statistical difference in incidence of concomitant diseases between groups A and B (group A 84.5 % vs. group B 74.6 %; P = 0.020). However, there was no difference between the groups with regard to indication for ERCP and type of intervention. There was no difference in postprocedure complication rate between very elderly patients and younger patients (< 80 years), except for prolonged sedation or hypotension, which occurred more frequently in older (≥ 80 years) than in younger (< 80 years) patients (7.6 % vs. 3.2 %; P = 0.037). In group B, complications necessitating re-admission after the 6-hour observation period occurred in 10 patients (2.09 %) (patients ≥ 80 years 0.8 % and patients < 80 years 2.5 %). The costs saved by performing the procedure on an outpatient basis was calculated as 150 € per patient.
Outpatient therapeutic ERCP with postprocedure observation of 6 hours is a safe and cost-effective procedure in a significant proportion of very elderly patients.
Capsule endoscopy (CE) remains the examination of choice for the investigation of obscure gastrointestinal bleeding. Although the factors predicting positive CE findings in the overall obscure ...gastrointestinal bleeding have been investigated, the clinical characteristics that predict a positive CE in patients with past overt obscure gastrointestinal bleeding (OOGIB) have not been systematically studied.
Between September 2004 and December 2013, 262 patients underwent CE for evaluation of past OOGIB after negative upper and lower endoscopy, and other diagnostic modalities. Patients' records were retrospectively reviewed to assess the factors that could possibly predict positive CE findings.
Two hundred and twenty four patients with a median age of 70 years (range: 17-87) were enrolled in the final analysis and were divided into two groups; those who had positive (group A: 118 patients) and those who had negative CE findings (group B: 106 patients). The overall diagnostic yield of CE was 52.68 %. Multivariate analysis demonstrated that age >65 years, anticoagulant use, antiplatelet use, and non-steroidal anti-inflammatory drugs use were independent predictive factors for positive findings on CE. Of the 118 patients with positive CE, therapeutic interventions were performed in 56 patients (47.46 %). Recurrence of bleeding presented in nine patients of group B compared with 39 patients of group A (p <0.001).
Certain clinical characteristics predict a positive CE in patients with past OOGIB. Patients with OOGIB and negative CE had a considerably lower rebleeding rate, and further invasive investigational procedures may be adjourned or may not be required, though such recommendation warrants further validation.

Barrett's esophagus(BE) is a premalignant condition associated with chronic gastro-esophageal reflux disease (GERD). As only a small proportion of BE progresses to malignancy, it is important to ...study BE prevalence to prevent adenocarcinoma.
Between January 2007 and December 2010, all consecutive individuals who underwent routine upper endoscopy were prospectively recruited. Patients referred for GERD were excluded from the study. Clinical and endoscopic data were collected.
A total of 1,990 patients (mean age 47.48±13.4 years; 52.8% males) were included. Of them, 496 (24.9%) reported GERD. Erosive esophagitis (EE) was found in 221 participants (11.1%, 193 patients with LA grade A and 28 patients with LA grade B). Overall 31 of 1494 participants not reporting reflux symptoms (2.07%) suffered from silent GERD. BE was diagnosed in 75 participants (3.77%), four (5.3%) with long-segment BE and 71 (94.7%) with short-segment BE. Low-grade dysplasia was noticed in 1 patient with long-segment BE. Hiatal hernia (HH) was found in 196 patients (9.8%), and mean HH length was 3.22 ± 0.2 cm. BE was correlated to EE, GERD and the presence of HH (p= 0.0167, <0.001 and 0.017, respectively) whereas it was not associated with age, alcohol consumption and smoking (p= 0.057, 0.099 and 0.06, respectively). BE was not correlated with Helicobacter pylori infection (p=0.542).
The prevalence of BE was 3.77% in a Greek population undergoing upper endoscopy not referred for GERD. Long-segment BE was very uncommon (0.2%) whereas 2.07% of patients not reporting symptoms suffered from silent GERD.
Objective: To evaluate the diagnostic yield of capsule endoscopy (CE) and its impact on treatment and outcome in patients without bleeding indications. Subjects and Methods: One hundred and ...sixty-five nonbleeding patients were enrolled in the study. The most common indications for CE were chronic abdominal pain alone (33 patients) or combined with chronic diarrhea (31 patients) and chronic diarrhea alone (30 patients). Among the 165 patients, 129 underwent CE for evaluation of gastrointestinal symptoms and 36 for surveillance or disease staging. Results: CE findings were positive, suspicious and negative in 73 (44.2%), 13 (7.9%) and 79 (47.9%) of cases, respectively. The diagnostic yield was highest in patients with refractory celiac disease (10/10, 100%) and suspected Crohn’s disease (5/6, 83.3%), followed by patients with chronic abdominal pain and chronic diarrhea (13/31, 41.9%), established Crohn’s disease (2/6, 33.3%), chronic diarrhea alone (8/30, 26.7%), chronic abdominal pain alone (8/33, 24.2%) and other indications (3/13, 23.1%) (p < 0.005). The CE findings led to a change of medication in 74 (47.7%) patients, surgery in 15 (9.7%), administration of a strict gluten-free or other special diet in 13 (8.4%) and had other consequences in 11 (6.7%). Management was not modified in 42 (27.1%) patients. Among symptomatic patients (n = 129), 29 (22.5%) were lost to follow-up. The remaining 100 patients were followed up for 8.7 ± 4.0 months (range 2–19). Among the latter, resolution or improvement of symptoms was observed in 86 (86%) patients, no change in 11 (11%) and 3 (3%) died. All 86 patients who experienced resolution or improvement of their symptoms had a modification of their management after CE; only 7/11 patients whose symptoms did not change (63.6%) and 2/3 patients who died (66.7%) had a modification of management (p < 0.001). Conclusions: CE appears to be a useful tool in the evaluation of patients with nonbleeding indications. The outcome of most patients with negative findings was excellent.
This prospective randomized study compared the patency and effective drainage rate of two stents with different materials but similar design, in the palliation of inoperable malignant biliary ...obstruction.
A total of 49 patients (26 women, mean age 72.55 +/- 10.75 years, range: 48-91 years) with obstructive jaundice due to inoperable malignant stricture of the distal common bile duct without previous drainage procedure, were randomly assigned to receive 10F Double Layer (DLS) (n = 24) or 10F Tannenbaum (TAN) (n = 25) biliary plastic stent. The diagnosis included pancreatic cancer (n = 33), cholangiocarcinoma (n = 8), ampullary cancer (n = 7) and metastatic lymphadenopathy (n = 1). The duration of stent patency, the effective drainage, and the adverse events were analyzed.
Stent placement was successful in all patients with minor complications. The overall median patency rates between the two groups did not differ (107.5 days for DLS group vs. 101 days for TAN group ; p = 0.066). Effective drainage rate at the end of second week was 95.8% for DLS group and 96% for TAN group, (p = 1.00). Proximal stent migration occurred in one patient with TAN stent.
The present study demonstrated that both DLS and TAN stents are comparable in terms of placement, overall stent patency, and complications.
Capsule endoscopy is an effective method of examining the small bowel in patients with obscure gastrointestinal bleeding, suspected inflammatory mucosal diseases and neoplasms. We herein evaluate the ...diagnostic yield of capsule endoscopy and its effect on clinical management in daily clinical practice.
One hundred and one capsule endoscopies performed at the Department of Endoscopy and Motility Unit of G. Gennimatas General Hospital of Thessaloniki from May 2007 to February 2009 were retrospectively reviewed. Clinical management following capsule endoscopy findings was evaluated. The most frequent indication was obscure gastrointestinal bleeding (n=56, overt=20).
The overall diagnostic yield was 47.5%. The diagnostic yield was 88.9% in patients with overt bleeding who underwent early capsule endoscopy (within 5 days), versus 36.4% in patients who underwent late capsule endoscopy (p=0.028). Moreover, it reached 81.8% in patients with abdominal pain, with/without diarrhea and abnormal biological markers, versus 8.3% in patients with normal biological markers (p<0.0001). Capsule endoscopy was diagnostic in all patients with symptomatic celiac disease. Adenomas were found in 9 of 14 familial adenomatous polyposis patients. Capsule retention (>72 hours) occurred in two patients. Forty-three of 48 (89.6%) patients with positive capsule endoscopy findings that received intervention or medical treatment had positive clinical outcomes.
Capsule endoscopy has an important diagnostic role and contribution in the clinical management during routine clinical practice; however, it remains to be determined which patients are more likely to benefit from this expensive examination.
