| Summary: | Background: - Postoperative paralytic ileus (POI) is a significant concern following gastrointestinal tumor surgery. Effective preventive and therapeutic strategies are crucial but remain elusive. Current evidence from randomized-controlled trials on pharmacological interventions for prevention or treatment of POI are systematically reviewed to guide clinical practice and future research. - Materials and methods: - Literature was systematically searched for prospective randomized-controlled trials testing pharmacological interventions for prevention or treatment of POI after gastrointestinal tumor surgery. Meta-analysis was performed using a random effects model to determine risk ratios and mean differences with 95% CI. Risk of bias and evidence quality were assessed. - Results: - Results from 55 studies, involving 5078 patients who received experimental interventions, indicate that approaches of opioid-sparing analgesia, peripheral opioid antagonism, reduction of sympathetic hyperreactivity, and early use of laxatives effectively prevent POI. Perioperative oral Alvimopan or intravenous administration of Lidocaine or Dexmedetomidine, while safe regarding cardio-pulmonary complications, demonstrated effectiveness concerning various aspects of postoperative bowel recovery [Lidocaine: −5.97 (−7.20 to −4.74)h, P<0.0001; Dexmedetomidine: −13.00 (−24.87 to −1.14)h, P=0.03 for time to first defecation; Alvimopan: −15.33 (−21.22 to −9.44)h, P<0.0001 for time to GI-2] and length of hospitalization [Lidocaine: −0.67 (−1.24 to −0.09)d, P=0.02; Dexmedetomidine: −1.28 (−1.96 to −0.60)d, P=0.0002; Alvimopan: −0.58 (−0.84 to −0.32)d, P<0.0001] across wide ranges of evidence quality. Perioperative nonopioid analgesic use showed efficacy concerning bowel recovery as well as length of hospitalization [−1.29 (−1.95 to −0.62)d, P=0.0001]. Laxatives showed efficacy regarding bowel movements, but not food tolerance and hospitalization. Evidence supporting pharmacological treatment for clinically evident POI is limited. Results from one single study suggest that Neostigmine reduces time to flatus and accelerates bowel movements [−37.06 (−40.26 to −33.87)h, P<0.0001 and −42.97 (−47.60 to −38.35)h, P<0.0001, respectively] with low evidence quality. - Conclusion: - Current evidence concerning pharmacological prevention and treatment of POI following gastrointestinal tumor surgery is limited. Opioid-sparing concepts, reduction of sympathetic hyperreactivity, and laxatives should be implemented into multimodal perioperative approaches. |
