A Novel Hands-Free Abdominal Compression Device for Colonoscopy Significantly Decreases Cecal Intubation Time: A Prospective Single-Blinded Pilot Study

The impact of abdominal compression devices on colonoscopy outcomes: a systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

Colonoscopy is the gold standard method for colorectal cancer screening. Looping occurs in 91% of cases undergoing colonoscopy and can cause patient discomfort, prolonged cecal intubation time (CIT), and colon perforation. This meta-analysis investigates the impact of abdominal compression devices (ACD) on colonoscopy outcomes.

METHODS

A systematic review and meta-analysis synthesizing randomized controlled trials (RCTs), retrieved by systematically searching: PubMed, EMBASE, WOS, SCOPUS, and Cochrane through February 2nd, 2023. Continuous and dichotomous outcomes were pooled using mean difference (MD) and risk ratio (RR) along with confidence interval (CI) using Revman. Our review protocol was prospectively published on PROSPERO with ID: CRD42023397344.

RESULTS

We included eight RCTs with a total of 1,889 patients. ACD was effective to decrease CIT (MD: -2.15 with a 95% CI [-3.49, -0.80], p = .002), postural change (RR: 0.57 with 95% CI [0.49, 0.66], p = .00001), and VAS pain score (MD: -1.49 with 95% CI [-1.81, -1.17], p = .0001). However, there was no difference between ACD and control groups regarding manual compression (RR: 0.65 with 95% CI [0.42, 1.00], p = .05), complete colonoscopy rate (CCR) (RR: 1.01 with 95% CI [0.99, 1.04], p = .31), and cecal intubation length (CIL) (MD: -2.25 with 95% CI [-7.64, 3.14], p = .41).

CONCLUSION

ACD during colonoscopy may enhance patient comfort by reducing CIT, pain, and postural changes. Nevertheless, additional RCTs are necessary to validate these results and determine the most suitable approach to utilize ACD for colonoscopy.

Factors affecting cecal intubation time during colonoscopy

In recent years, the morbidity and mortality of colorectal cancer (CRC) have increased significantly in China, and it has become one of the major malignancies that threaten the health of residents. Colonoscopy is the gold standard for the diagnosis of CRC. High-quality colonoscopy can effectively reduce the mortality of CRC. Cecal intubation time (CIT) is one of the indicators to reflect the quality of colonoscopy. Studies have found that many factors can affect CIT. This paper reviews the literature to identify the factors that affect CIT, such as those related to doctors, patients, assistive technologies, and equipment, in order to improve the quality of colonoscopy performed by endoscopists.

Application of a Positioning Wedge During Colonoscopy of Obese Patients to Mitigate Nurse Pain

Background: The application of external abdominal pressure by endoscopy nurses has long been recognized to facilitate passage of the endoscope during colonoscopy. Applying sustained abdominal pressure during a colonoscopy for an obese patient is especially challenging and may result in musculoskeletal injury for the endoscopy nurse. Methods: Four experienced endoscopy nurses cared for 100 obese adult patients scheduled for colonoscopy who had a body mass index (BMI) greater than 25 kg/m². Duration of applied pressure, as well as nurse pain and fatigue were examined after they cared for 50 patients with and 50 patients without a positioning wedge. Findings: No difference in the mean fatigue score between nurses providing standard care versus those using the positing wedge was observed (mean score: 2.6 vs. 2.0, respectively); however, self-reported pain was higher for those providing standard care relative to those using the positioning wedge (mean score: 2.9 vs. 1.3, p = .0143). In 18 patients who required both the wedge and pressure, these nurses still reported lower pain scores relative to nurses who provided care without a wedge (M = 1.3 vs. 2.9, respectively). Conclusion/Application to practice: A positioning wedge for obese patients undergoing a colonoscopy can reduce the need for external abdominal pressure applied by endoscopy nurses. Occupational health nurses should endorse the use of a gel wedge to promote safe patient handling and reduce the potential for musculoskeletal injury among endoscopy nurses.
