The Effect of Virtual Reality on Pain and Anxiety During Colonoscopy: A Randomized Controlled Trial

Background The aim of the study is to evaluate the effect of virtual reality application during a colonoscopy on the pain and anxiety experienced by patients.Methods The study was conducted as experimental, randomized, controlled research. The study was carried out between October 15, 2017 and May 20, 2018 in the Endoscopy Unit of a Public Hospital in northern Turkey. The study sample consisted of 60 patients who underwent colonoscopy. The patients were divided into 2 groups by using simple randomization. The patients in the experimental group watched virtual reality applications during colonoscopy, whereas the patients in the control group underwent standard colonoscopy protocol. Colonoscopy was performed on patients in both groups by the same gastroenterologist without the use of anesthesia. The demographic data of both groups, pain levels during and after the procedure, before and after the procedure anxiety levels were evaluated.Results The mean age of the patients in the experimental group was 56.33 ± 11.81, the mean age of the patients in the control group was 56.20 ± 15.62. There was no statistically significant difference between the pre- and post-operative state anxiety score averages of the patients in the experimental and control groups. There was a statistically significant difference between the trait anxiety scores (P < .000) and pain scores (P < .03) during the procedure between both groups.Conclusion The virtual reality application was found to reduce patients’ pain during the colonoscopy procedure. The virtual reality application, an easily available, inexpensive, and non-invasive method, can be used by nurses in pain management during colonoscopy.

Preparation for Colonoscopy in Hospitalized Patients

Successful colonoscopy depends on good preparation of the colon before the procedure. Inadequate preparation may lead to cancelled or repeat procedures and compromise patient safety, quality of care, and cost effectiveness. The primary aim of this study was to isolate factors that affect preparation success, especially in older, more severely ill, bedridden patients. The secondary aim was to examine the possible differences in preparation quality between ambulatory and hospitalized patients and the impact of a staff educational program on the preparation of hospitalized patients for colonoscopy. The study group included 303 consecutive ambulatory patients and 104 hospitalized patients referred for colonoscopy between January and March 2002, before the department introduced an educational program on colonoscopy preparation, and 310 ambulatory patients and 105 hospitalized patients referred for colonoscopy between January and March 2003. All patients completed an ad hoc questionnaire, and the findings were compared between ambulatory and hospitalized patients and between patients treated before and after the educational program. Polyethylene glycol was used significantly more often for colonoscopy preparation in hospitalized patients than in ambulatory patients (53.1% versus 8.8%; P=.0001). The hospitalized group was characterized by more incomplete or repeated colonoscopies and poorer preparation quality. On multivariate analysis, the variables found to be independent predictors of good preparation were successful patient completion of the preparatory procedure according to instructions, colonoscopy performed for follow-up after polypectomy, and preparation with sodium phosphate. The educational intervention had no impact on the quality of preparation. In conclusion, sodium phosphate preparation and complete adherence to preparation instructions are the most important factors for successful colonoscopy preparation. Current preparatory methods for hospitalized and severely ill patients need to be revised.     

Low-volume oral colonoscopy bowel preparation: sodium phosphate and magnesium citrate

BACKGROUND: Low-volume oral colonoscopy preparations are easier to tolerate and are gaining popularity at the expense of large-volume lavage solutions. The aims of this two-part study were to compare two oral colonoscopy bowel preparations, sodium phosphate (NaP) and magnesium citrate (Mg), and to assess the effects of timing and dilution of NaP. METHODS: Part 1 included 300 ambulatory patients randomized to receive NaP or Mg on the day before colonoscopy. Patients completed a questionnaire before colonoscopy. The endoscopist, blinded to the type of bowel preparation, rated bowel cleansing and recorded the presence of any rectosigmoid aphthous ulcers. In part 2, a total of 297 patients received NaP diluted into 3 doses 10 minutes apart the evening before and the morning of the day of colonoscopy. This group was compared with the group in part 1 that received NaP in two separate single doses entirely the day before colonoscopy. RESULTS: NaP and Mg were well tolerated. When preparations were taken the day before colonoscopy, Mg achieved better bowel cleansing (p < 0.001). Taking NaP entirely the day before colonoscopy resulted in poor right colon cleansing (27%). In contrast, taking NaP the evening before and morning of colonoscopy improved cleansing in the right colon (p < 0.001). Vomiting occurred less frequently with dilution of NaP. Rectosigmoid aphthous ulcers occurred more often with NaP (5.5%) than Mg (1%), p < 0.01. For patients who, according to questionnaire, had received a previous bowel preparation, NaP and Mg were both preferred over large-volume lavage solutions, whereas NaP was preferred over Mg. CONCLUSIONS: When taken entirely the day before colonoscopy, Mg is superior to NaP. Taking NaP the evening before and morning of colonoscopy improved bowel cleansing compared with taking it entirely the day before. Dilution of NaP reduces vomiting. NaP induces rectosigmoid aphthous ulcers more often than Mg.     

Dynamic computed tomography is useful for the diagnosis and colonoscopic treatment of colonic diverticular bleeding

We investigated whether emergency dynamic computed tomography (CT) is helpful to identify bleeding colonic diverticulum treatable by colonoscopy. We enrolled 95 consecutive patients given diagnoses of colonic diverticular bleeding at Hiroshima City Hospital in the present study, of whom 60 underwent CT before colonoscopy (CT group), and 35 underwent colonoscopy alone (CS group). In the CT group, bleeding diverticula were identified and treated by colonoscopy in 31 of 32 (96.9%) patients in whom extravasation was detected by CT. The interval between bleeding being recognized and CT (median 1.0 hours) in patients in whom extravasation was detected by CT was shorter than that in whom extravasation was not detected (median 5.0 hours). To identify and treat bleeding diverticula by colonoscopy, the use of emergency dynamic CT prior to colonoscopy is recommended.
