Abstract:
Obesity in individuals can have consequences ranging from metabolically healthy obesity to serious morbidities and reduce the quality and duration of life. A meta-analysis was conducted to assess the role of abdominal drainage on postoperative complications after bariatric surgery. PubMed, Embase, and the Cochrane Library were systematically searched for eligible studies. The results revealed that abdominal drainage was associated with surgical complications, with a pooled odds ratio (OR) of 1.70 (P < .001), but not associated with wound infection (OR: 1.04; P = .762). Associations with surgical complications were mainly detected from retrospective cohort studies. The use of abdominal drainage showed associations with death (OR: 1.68; P < .001) and reoperation (OR: 1.49; P < .001). These findings revealed that abdominal drainage during bariatric surgery was associated with surgical complications, death, and reoperation. These results should be taken with caution since randomized controlled trials and retrospective studies were analyzed together.
