Abstract
Objective: The impact of obesity on the surgical outcomes in patients after laparoscopic liver resection (LLR) is unclear. We aimed at conducting a meta-analysis to evaluate the associations between overweight and obesity and major surgical outcomes after LLR for liver tumors.
Methods: We searched PubMed, Cochrane Library, Embase, and Web of Science databases for eligible studies. Odds ratios (ORs) and mean differences (MDs) with 95% confidence intervals (CIs) were calculated.
Results: Eight studies were included, with a total of 7,580 patients. Findings indicated that, relative to individuals of normal weight, those in the higher body mass index (BMI) category (overweight and obese) had prolonged operation time (MD, 15.46 mins), increased blood loss (MD, 39.40 mL), overall complications (OR 1.20), conversion (OR 1.41), and surgical site infection (SSI) (OR 1.77). In addition, subgroup analysis showed that although overweight did not increase the risk of overall postoperative complications and SSI, obesity significantly increased the risk of overall postoperative complications, SSI, and conversion to laparotomy.
Conclusion: In conclusion, higher BMI, especially obesity, is closely associated with higher risk of morbidity after laparoscopic liver resection.
期刊介绍:
This timely publication reports and reviews current findings on the effects of nutrition on the etiology, therapy, and prevention of cancer. Etiological issues include clinical and experimental research in nutrition, carcinogenesis, epidemiology, biochemistry, and molecular biology. Coverage of therapy focuses on research in clinical nutrition and oncology, dietetics, and bioengineering. Prevention approaches include public health recommendations, preventative medicine, behavior modification, education, functional foods, and agricultural and food production policies.
