Background: Adequate colon preparation is a critical component of high-quality colonoscopy especially for inpatients undergoing colonoscopy for acute indications. Inpatient colonoscopy has a high incidence of inadequate preparations. We report implementation of a multifaceted quality improvement intervention to improve inpatient colonoscopy preparations.

Methods: Bowel preparation quality from inpatient colonoscopies performed for the 12 months prior to the comprehensive intervention were compared to colonoscopies performed for 12 months following the intervention. The intervention had multiple components including: 1) EMR-based colonoscopy preparation order set; 2) automated EMR alerts prompting nursing assessment of preparation progress; 3) standardized nursing charting processes for tracking preparation progress; and 4) standardized education for nursing staff and ordering providers on adequate colon preparation, assessment of colon preparation quality, and use of the above processes; and print and video patient education materials.

Results: Two hundred thirty-eight inpatient colonoscopies were performed in the preintervention assessment period and 163 colonoscopies in the postintervention period. Median preintervention Boston Bowel Preparation Score (BBPS) was 6 and 26% of patients had inadequate colon preparation. Median postintervention BBPS was 8 with 16% inadequate colon preparation (P=0.016). The postintervention group had less ASA class I patients and used a lower dose of fentanyl than the preintervention group. There were no other significant differences between the pre- and postintervention groups.

Conclusions: Implementation of a comprehensive colon preparation quality intervention resulted in significantly improved inpatient colon preparation quality and decreased frequency of inadequate preparations. The intervention consisting of an EMR-based order-set, nursing alerts and charting process, and patient education materials is continually being refined.

Background: Assessing the potential effects of a low fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) diet on functional gastrointestinal symptoms, particularly upper gastrointestinal symptoms, is not clearly understood. The current study aimed to explore the association of a diet low in FODMAPs with uninvestigated chronic dyspepsia (UCD) and functional dyspeptic symptoms in a large population of Iranian adults.

Methods: This cross-sectional study was conducted on 2987 adults. Dietary FODMAPs intake estimated using a validated food-frequency questionnaire. UCD, early satiation, postprandial fullness and gastric pain were determined using a modified and validated version of the Rome III Questionnaire.

Results: After controlling for various confounders, consumption of a diet low in FODMAPs was associated with increased risk of UCD in the whole population (OR=1.85; 95% CI: 1.23-2.78; P=0.009) and women (OR=2.41; 95% CI: 1.46-3.95; P=0.004), but not in men. Higher consumption of a low-FODMAPs diet was related to increased risk of postprandial fullness (OR=1.38; 95% CI: 1.08-1.78; P=0.046). The inverse association between FODMAPs and epigastric pain tended to be significant after controlling for eating behaviors (OR=1.31; 95% CI: 0.98-1.76; P=0.084). No significant association was observed for early satiation.

Conclusions: Our data suggest that consumption of a low-FODMAPs diet may increase the risk of UCD and postprandial fullness; however, well-planned randomized controlled trials and prospective cohorts are required to ascertain the effect of FODMAPs on upper gastrointestinal symptoms.

Background: The aim of this study was to investigate the clinical value of preoperative colonoscopy combined with right gastroepiploic vein preservation (RGV) in radical resection of colorectal cancer for right colon cancer.

Methods: A total of 120 patients with right colon cancer in our hospital from February 2019 to October 2021 were selected and randomly divided into study group (RGV preserved during operation) and control group (RGV not preserved during operation), with 60 cases in each group. Perioperative parameters, intestinal fatty acid binding protein (I-FABP), Pittsburgh Sleep Quality Index (PSQI), total protein (TP), D-lactate (D-LA), quality of life scale (SF-36) scores, incidence of complications, and tumor recurrence rate were compared between the two groups.

Results: Duration of hospitalization was shorter in the study group than in the control group (P<0.05). Six months after surgery, I-FABP, D-LA levels and PSQI scores were lower, and TP levels and SF-36 scores were higher in the study group than in the control group (P<0.05). The incidence of complications in the study group (11.67% vs. 33.33%) was lower than that in the control group (P<0.05). There was no significant difference in tumor recurrence rate 6 months after operation between the two groups (P>0.05).

Conclusions: Preoperative colonoscopy combined with RGV preservation in radical resection of colorectal cancer for right colon cancer can avoid surgical trauma caused by unnecessary transection, reduce gastrointestinal function damage, promote physical rehabilitation and shorten hospital stay, and reduce the risk of complications such as gastroparesis.

Background: It was reported that about 60% of the physicians in the USA believed that their Gastroenterology fellowship poorly prepared them for large polyp resection. The aim of this study was to compare endoscopic mucosal resection (EMR) efficacy and complication rates between skilled general gastroenterologists who perform high volume of EMR and advanced endoscopists.

Methods: We identified 140 patients with documented large colonic polyps treated by 4 providers using EMR technique at Carilion Clinic, in Roanoke, Virginia, USA between 01/01/2014-12/31/2017, with follow-up through 10-2018. Information on demographics, clinical and pathological features of high-risk polyps (i.e., size, histology, site, and degree of dysplasia), timing of surveillance endoscopies, tools used during resection, and skills of performing endoscopist's were extracted. The cumulative risks of polyp recurrence after first resection using EMR technique were estimated using Kaplan-Meier curves.

Results: One hundred and forty patients were identified (mean age, 64.1±11.2 years; 47.1% males). Fifty-five polyps (39.3%) were removed by 2 skilled gastroenterologists and 85 (60.7%) were removed by advanced endoscopists. Most of the polyps resected were located in the right colon (63.6%) and roughly half of the polyps were removed in piecemeal fashion. At follow-up endoscopy, the advanced endoscopy group had lower polyp recurrence rates. The median recurrence after polypectomy was significantly different between the groups (0.88 and 1.03 years for skilled gastroenterologists who did not complete and completed EMR hands-on workshops; respectively vs. 3.99 years for the advanced endoscopist who did not complete EMR hands-on workshop, P=0.03).

Conclusions: There is a need for additional EMR training since polyp recurrence was significantly different between the groups despite high rates of piecemeal resection in the advanced endoscopy groups.

Background: Life expectancy and the number of ultra-octogenarians increased significantly, thus making crucial the appropriateness of several endoscopic procedures in elderly patients. The aim of our study was to provide a retrospective analysis of the efficacy and safety of capsule endoscopy (CE) in patients aged over 80 years.

Methods: In this single-centre study, 900 patients underwent capsule endoscopy between 2002 and 2015 for different indications; of these 106 patients aged ≥80 years (group A) and 99 patients aged 40-60 years (control group B) were retrospectively selected.

Results: Occult gastrointestinal bleeding accounted for 62.1% of all indications for capsule endoscopy in group B, compared to 95.2% in group A (P<0.001). Although not statistically significant, the diagnostic yield was higher in group A (71%) vs. group B (62%). The percentages of reaching the cecum and the median gastric transit time were uniform within the two groups. In contrast, small bowel transit time was longer in group A vs. B. Small bowel preparation was similar in the two groups. The exam was generally well tolerated in both groups, with capsule aspiration being one of the main adverse events, which occurred in two elderly patients.

Conclusions: Our data expand previous findings confirming that capsule endoscopy can be performed safely even in very old patients and show that the diagnostic yield is similar to that of younger patients.
