international guidelines recommend a routine colonoscopy to rule out advanced neoplasm after an acute diverticulitis event. However, in recent years, this recommendation has been called into question ...following the advent of computerized tomography (CT), particularly with regard to uncomplicated diverticulitis. Furthermore, colonoscopy is associated with a risk and additional costs.
to understand the diagnostic yield, quality and safety of colonoscopy in the setting of acute diverticulitis.
this was a retrospective study of all patients diagnosed with acute diverticulitis via CT between 2005 and 2013, who subsequently underwent a colonoscopy.
two hundred and sixteen patients diagnosed with acute diverticulitis via CT were enrolled. These included 58 cases with complicated diverticulitis (27%) and 158 with uncomplicated diverticulitis (73%). An advanced neoplasm was found in 12 patients (5.6%); 11.7% were complicated and 3.2% were uncomplicated (p = 0.02). No major complications were identified. The quality was low but improved over time; the complete procedure rate was 88%, an effective preparation was achieved in 75% and excision of polyps < 2 cm was performed in 78% of cases. The optimum colonoscopy quality cu-off was 9.5 weeks.
routine colonoscopy is advisable after a complicated diverticulitis event but its recommendation is unclear with regard to uncomplicated episodes. Colonoscopy is safe even when performed early. The overall quality is low but may be optimized via a subsequent endoscopy, two months after a diverticulitis diagnosis.
Abstract
Background and study aims Effective bowel cleansing is critical
for detecting lesions during colonoscopy, highlighting the importance of bowel preparations.
1L polyethylene glycol (PEG) + ...ascorbate (Asc) is the only recommended 1L PEG product in
Europe and the United States. Its efficacy was demonstrated in large-scale controlled trials
and confirmed in smaller-scale real-world studies. However, no large-scale real-world data
exist.
Patients and methods This observational, retrospective,
multicenter study, used outpatient follow-up data from medical records from 10 centers in
Spain and two in Portugal. Outpatients aged ≥18 years using 1L PEG + Asc as bowel preparation
were included. The main outcome measures were overall adequate colon cleansing (Boston Bowel
Preparation Scale BBPS score ≥6 with BBPS score ≥2 in each segment) and high-quality
cleansing of the right colon (BBPS score=3).
Results Data from 13169 eligible patients were included. Overall
cleansing success was achieved in 89.3% (95%CI 88.7%-89.8%) and high-quality cleansing in the
right colon in 49.3% (95%CI 48.4%–50.2%) of patients. For the overnight split-dose and
same-day regimens, overall adequate quality cleansing success rate was 94.7% and 86.7% (P<0.0001) and high-quality cleansing of the right colon rate was
65.4% and 41.4% (P<0.0001), respectively. Colonoscopy was
completed in 97.3% of patients, with non-completion due to poor preparation in only 0.8%; 2.3%
of patients experienced at least one adverse event (AE).
Conclusions This large-scale, real-world study demonstrates the
effectiveness of 1L PEG + Asc in the total and right colon, with a low percentage of patients
with AEs in routine clinical practice.

Abstract
Background
The most important predictor of unsuccessful bowel preparation is previous failure. For those patients with previous failure, we hypothesized that a nurse-led educational ...intervention by telephone shortly before the colonoscopy appointment could improve cleansing efficacy.
Methods
We performed a multicenter, endoscopist-blinded, randomized controlled trial. Consecutive outpatients with previous inadequate bowel preparation were enrolled. Both groups received the same standard bowel preparation protocol. The intervention group also received reinforced education by telephone within 48 hours before the colonoscopy. The primary outcome was effective bowel preparation according to the Boston Bowel Preparation Scale. Intention-to-treat (ITT) analysis included all randomized patients. Per-protocol analysis included patients who could be contacted by telephone and the control cases.
Results
657 participants were recruited by 11 Spanish hospitals. In the ITT analysis, there was no significant difference between the intervention and control groups in the rate of successful bowel preparation (77.3 % vs. 72 %;
P
= 0.12). In the intervention group, 267 patients (82.9 %) were contacted by telephone. Per-protocol analysis revealed significantly improved bowel preparation in the intervention group (83.5 % vs. 72.0 %;
P
= 0.001).
Conclusion
Among all patients with previous inadequate bowel preparation, nurse-led telephone education did not result in a significant improvement in bowel cleansing. However, in the 83 % of patients who could be contacted, bowel preparation was substantially improved. Phone education may therefore be a useful tool for improving the quality of bowel preparation in those cases.
Background and objectives: the impact of surgical primary tumor resection on survival of obstructive metastatic colorectal cancer remains controversial. The primary goal of this study was to analyze ...survival in patients with obstructive metastatic colorectal cancer after treatment with either resection surgery or a colonic stent. Material and methods: a prospective study was performed of all patients with stage-IV colorectal cancer and obstructive manifestations, diagnosed from 2005 to 2012 and managed with either resection surgery or a colonic stent. Cases with a perforation, abscess, right colon or distal rectal malignancy, multiple colorectal cancer or derivative surgery were excluded. Results: a total of 95 patients were included, 49 were managed with resection surgery and 46 with a colonic stent. The colonic stent group had a higher Charlson index (9.5 + or - 2.1 vs 8.6 + or - 1.5, p = 0.01), a shorter time to oral intake (0.9 + or - 1.1 vs 16.4 + or - 53.5 days, p = 0.05), a shorter hospital stay (4 + or - 4.8 vs 16.7 + or - 15.5 days, p = 0.0001), less need for stomata (11.1 % vs 32.7 %, p = 0.01), fewer early complications (4.3 % vs 46.9 %, p = 0.0001) and more late complications (33.3 % vs 6.4 %, p = 0.001). Undergoing chemotherapy (p = 0.008) was the only independent factor related to increased survival. In the subgroup of patients managed with chemotherapy, surgical primary tumor resection was an independent factor associated with increased survival. Conclusion: both treatments are effective for resolving obstructive manifestations in patients diagnosed with stage-IV obstructive colorectal cancer. Resection surgery has no positive impact on survival and thus cannot be recommended as a therapy of choice. Keywords: Colorectal cancer. Survival. Surgery. Stent.
Objectives
When bowel preparation (BP) is inadequate, international guidelines recommend repeating the colonoscopy within 1 year to avoid missing clinically relevant lesions. We aimed to determine ...the rate of missed lesions in patients with inadequate BP through a very early repeat colonoscopy with adequate BP.
Methods
Post hoc analysis was conducted using data collected from a prospective multicenter randomized clinical trial including patients with inadequate BP and then repeat colonoscopy. Inadequate BP was defined as the Boston Bowel Preparation Scale (BBPS) score <2 points in any segment. We included patients with any indication for colonoscopy. The adenoma detection rate (ADR), advanced ADR (AADR), and serrated polyp detection rate (SPDR) were calculated for index and repeat colonoscopies.
Results
Of the 651 patients with inadequate BP from the original trial, 413 (63.4%) achieved adequate BP on repeat colonoscopy. The median interval between index and repeat colonoscopies was 28 days. On repeat colonoscopy, the ADR was 45.3% (95% confidence interval CI 40.5–50.1%), the AADR was 10.9% (95% CI 8.1–14.3%), and the SPDR was 14.3% (95% CI 10.9–17.7%). Cancer was discovered in four patients (1%; 95% CI 0.2–2.5%). A total of 60.2% of all advanced adenoma (AA) were discovered on repeat colonoscopy. A colon segment scored BBPS = 0 had most AA (66.1%) and all four cancers.
Conclusion
Patients with inadequate BP present a high rate of AAs on repeat colonoscopy. When a colonoscopy has a colon segment score BBPS = 0, we recommend repeating the colonoscopy as soon as possible.
