ABSTRACT
BACKGROUND: To investigate whether a text message intervention improves adherence to preoperative exercise advice prior to laparoscopic sleeve gastrectomy (LSG). METHODS: A single-blinded parallel design 1:1 ratio randomized controlled trial was performed in patients undergoing LSG as a single-stage bariatric procedure for morbid obesity. The intervention group received preoperative daily text messages. The primary outcome was adherence to preoperative exercise advice as assessed by the number of participants partaking in ≥450 metabolic equivalent minutes (METmin-1 ) exercise activity per week preoperatively. RESULTS: Eighty-eight patients were included in the analysis with 44 allocated to each arm. Adherence and exercise activity increased significantly from baseline in the exposure group (EG) but not in the control group (CG). Adherence was significantly higher in the EG at the end of the intervention period compared to the CG. Despite increased exercise activity, there was no improvement in 6-min walk test or surgical recovery. CONCLUSION: A daily text message intervention improved adherence to preoperative exercise advice, but this did not correlate with improved surgical recovery.
ABSTRACT
INTRODUCTION: Post-operative ileus (POI) is a major problem following elective abdominal surgery. Several studies have been published investigating the use of chewing gum to reduce POI. These studies however, have produced variable results. Thus, there is currently no consensus on whether chewing gum should be widely instituted as a means to help reduce POI. METHODS: We performed a systematic literature review to evaluate whether the use of chewing gum post-operatively improves POI in abdominal surgery. A comprehensive review of the literature was conducted according to the guidelines in the PRISMA statement. The following databases were searched: MEDLINE, PUBMED, EMBASE, SCOPUS, Science Direct, CINAHL and the Cochrane Central Register of Controlled Trials. Clinical outcomes were extracted and meta-analysis was performed. RESULTS: There were 1019 patients from 12 randomised controlled studies included in this review. Only one study was conducted in an Enhanced Recovery after Surgery (ERAS) environment. Seven of the twelve studies concluded that chewing gum reduced post-operative ileus. The remaining five studies found no clinical improvement. Overall, there was a small benefit in reducing time to flatus, and time to bowel motion, but no difference in the length of stay or complications. CONCLUSION: Chewing gum offers only a small benefit in reducing time to flatus and time to passage of bowel motion following abdominal surgery. This benefit is of limited clinical significance. Further studies should be conducted in a modern peri-operative care environment.
