RESUMO
BACKGROUND: As one of the complications after abdominal operation, early postoperative inflammatory small bowel obstruction (EPISBO) is a great trouble for many patients. The use of somatostatin in treating this disease had been widely reported, but its efficacy and safety were controversial. Therefore, the present research carried out a systematic review of the clinical efficacy and safety of somatostatin in treating EPISBO. METHODS: Computer retrieval was conducted in foreign databases (including PubMed, The Cochrane Library, and Embase) and Chinese database (including Sino Med, CNKI, VIP, and WangFang Data), supplementary search for the literatures included was performed, and manual retrieval was performed in abstracts, books, and non-electronic magazines related to the present research to ensure the recall rate. Among all republished relevant experimental studies in Chinese and English from January 1, 1996 to February 1, 2020, randomized controlled trials on the curative efficacy of somatostatin for EPISBO were collected. The evaluation measures included patients' total effective rate, peristaltic sound recovery time, time of disappearance of abdominal pain, time of first defecation after operation, drainage of gastrointestinal decompression and length of stay after treatment. The literatures were selected by two investigators independently to extract data according to the inclusion and exclusion criteria, Bias Risk Assessment Tool recommended by Cochrane Review Hand book 5.2 was used to assess literature quality, and meta-analysis was carried out by using soft Stata 12.0. RESULTS: This study will scientifically and effectively analyze the clinical efficacy and safety of somatostatin in the treatment of EPISBO through systematic review and meta-analysis. ETHICS AND DISSEMINATION: The results of this study will be published in a peer-reviewed SCI journal to provide evidence-based medical evidence for the clinical treatment of early postoperative inflammatory bowel obstruction.
