Evidence Summary for Prevention of Gastrointestinal Dysfunction After Laparoscopic Surgery

Post-operative gastrointestinal dysfunction (PGD) leading to nausea, vomiting, and abdominal distension are common complications after laparoscopic surgery for abdominal diseases. However, there is still a lack of evidence-based guidelines or evidence summaries for the prevention of Post-operative gastrointestinal dysfunction. The purpose of this study is to retrieve and summarize the best evidence for the prevention of post-operative gastrointestinal dysfunction. Evidence, including guidelines, systematic reviews, meta-analyses, expert consensus, and evidence summaries related to the prevention of post-operative gastrointestinal dysfunction were retrieved from Chinese and English electronic databases up to November 2021. Appraisal of guidelines for research and evaluation, A MeaSurement Tool to Assess Systematic Reviews [AMSTAR], the JBI literature quality assessment tool, and the JBI Evidence Pre-ranking and Evidence Recommendation Grade System were used. A total of 4 guidelines, 1 evidence summary, and 5 expert consensus, as well as 17 systematic reviews and meta-analyses were included in our study. We summarized 29 pieces of evidence from 19 aspects of peri-operative period as follows: 9 level I, 13 level II, 5 level III, and 2 level IV pieces of evidence. The evidence recommendation was grade A for 18 pieces of evidence, and grade B for 11. As PGD remains a common complication of laparoscopic surgery, the 29 pieces of evidence summarized in this study can provide some reference for the prevention and management of gastrointestinal dysfunction after laparoscopic surgery.
