The Use of Mechanical Bowel Preparation in Pelvic Reconstructive Surgery: A Randomized Controlled Trial.

ABSTRACT: To compare mechanical bowel preparation (MBP) using oral magnesium citrate with sodium phosphate enema to sodium phosphate (NaP) enema alone during minimally invasive pelvic reconstructive surgery.We conducted a single-blind, randomized controlled trial of MBP versus NaP in women undergoing minimally invasive pelvic reconstructive surgery. The primary outcome was intraoperative quality of the surgical field. Secondary outcomes included surgeon assessment of bowel handling and patient-reported tolerability symptoms.One hundred fifty-three participants were enrolled; 148 completed the study (71 MBP and 77 NaP). Patient demographics, clinical and intraoperative characteristics were similar. Completion of assigned bowel preparation was similar between MBP (97.2%) and NaP (97.4%). The MBP group found the preparation more difficult (P<0.01) and reported more overall discomfort and negative preoperative side effects (all P?0.01). Quality of surgical field at initial port placement was excellent/good in 80.0% of the MBP group compared with 62.3% in the NaP group (P=0.02). This difference was not maintained by the conclusion of surgery (P=0.18). Similar results were seen in the intent-to-treat population. Surgeons accurately guessed preparation 65.7% of the time for MBP versus 41.6% for NaP (P=0.36). At 2 weeks postoperatively, both reported a median time for return of bowel function of 3.0 (2.0-4.0) days.Mechanical bowel preparation with oral magnesium citrate before minimally invasive pelvic reconstructive surgery offered initial improvement in the quality of surgical field, but this benefit was not sustained. It was associated with an increase in patient discomfort preoperatively, but did not seem to impact postoperative return of bowel function.I.

Project description:ObjectiveTo compare surgeons' intraoperative surgeon acceptability or assessment of the operative field regarding bowel contents and patients' satisfaction with or without a mechanical bowel preparation before reconstructive vaginal prolapse surgery.MethodsIn this single-blind, randomized trial, women scheduled to undergo vaginal prolapse surgery with a planned apical suspension and posterior colporrhaphy were allocated using block randomization to an intervention or control group. Surgeons were blinded to patient allocation. One day before surgery, mechanical bowel preparation instructions consisted of a clear liquid diet and two self-administered saline enemas; the participants in the control group sustained a regular diet and nothing by mouth after midnight. The primary outcome was surgeons' intraoperative assessment of the surgical field regarding bowel content as measured on a 4-point Likert scale (1, excellent; 4, poor). Secondary outcomes included participant satisfaction and bowel symptoms. The primary outcome was determined by intention-to-treat analysis and other analyses were per protocol.ResultsOf the 150 women randomized (75 women to intervention and control group), 145 completed the study. No differences existed in the demographic, clinical, and intraoperative characteristics between groups (P>.05). Surgeons' intraoperative assessment rating was 85% "excellent or good" with bowel preparation compared with 90% for participants in the control group (odds ratio [OR] 0.59, 95% confidence interval [CI] 0.21-1.61; P=.30). The bowel preparation group was less likely to report "complete" satisfaction compared with the participants in the control group (OR 0.11, 95% CI 0.04-0.35; P<.001). Abdominal fullness and cramping, fatigue, anal irritation, and hunger pains were greater in the bowel preparation group (all P<.01).ConclusionBefore reconstructive vaginal surgery, mechanical bowel preparation conferred no benefit regarding surgeons' intraoperative assessment of the operative field, reflected decreased patient satisfaction, and had increased abdominal symptoms.Clinical trial registrationClinicalTrials.gov, www.clinicaltrials.gov, NCT01431040.Level of evidenceI.

Project description:BackgroundAdequate bowel preparation is essential for the visualization of the colonic mucosa during colonoscopy. However, the rate of inadequate bowel preparation is still high, ranging from 18% to 35%; this may lead to a higher risk of missing clinically relevant lesions, procedural difficulties, prolonged procedural time, an increased number of interval colorectal carcinomas, and additional health care costs.ObjectiveThe aims of this study are to compare bowel preparation instructions provided via a personalized smartphone app (Prepit, Ferring B V) with regular written instructions for bowel preparation to improve bowel preparation quality and to evaluate patient satisfaction with the bowel preparation procedure.MethodsEligible patients scheduled for an outpatient colonoscopy were randomized to a smartphone app group or a control group. Both the groups received identical face-to-face education from a research physician, including instructions about the colonoscopy procedure, diet restrictions, and laxative intake. In addition, the control group received written information, whereas the smartphone app group was instructed to use the smartphone app instead of the written information for the actual steps of the bowel preparation schedule. All patients used bisacodyl and sodium picosulfate with magnesium citrate as laxatives. The quality of bowel preparation was scored using the Boston Bowel Preparation Scale (BBPS) by blinded endoscopists. Patient satisfaction was measured using the Patient Satisfaction Questionnaire-18.ResultsA total of 87 patients were included in the smartphone app group and 86 in the control group. The mean total BBPS score was significantly higher in the smartphone app group (mean 8.3, SD 0.9) than in the control group (mean 7.9, SD 1.2; P=.03). The right colon showed a significantly higher bowel preparation score in the smartphone app group (mean 2.7, SD 0.5 vs mean 2.5, SD 0.6; P=.04). No significant differences were observed in segment scores for the mean transverse colon (mean 2.8, SD 0.4 vs mean 2.8, SD 0.4; P=.34) and left colon (mean 2.8, SD 0.4 vs mean 2.6, SD 0.5; P=.07). General patient satisfaction was high for the smartphone app group (mean 4.4, SD 0.7) but showed no significant difference when compared with the control group (mean 4.3, SD 0.8; P=.32).ConclusionsOur personalized smartphone app significantly improved bowel preparation quality compared with regular written instructions for bowel preparation. In particular, in the right colon, the BBPS score improved, which is of clinical relevance because the right colon is considered more difficult to clean and the polyp detection rate in the right colon improves with improvement of bowel cleansing of the right colon. No further improvement in patient satisfaction was observed compared with patients receiving regular written instructions.Trial registrationClinicalTrials.gov NCT03677050; https://clinicaltrials.gov/ct2/show/NCT03677050.
