Abstract Background In laparoscopic gastrectomy, liver retraction is an important procedure to obtain a sufficient operative view to ensure the quality of surgery. However, postoperative liver dysfunction is frequently encountered after liver retraction. This study aims to explore the effect of a modified liver retraction method (MLR) we designed on the postoperative liver function of patients receiving laparoscopic radical gastrectomy. Methods The data of patients who underwent laparoscopic gastrectomy by a single surgical group from August 2021 to April 2024 were retrospectively analyzed. These patients underwent laparoscopic gastrectomy without liver biopsy, partial hepatectomy, or cholecystectomy. We divided 218 patients into two groups based on the liver retraction method used, either MLR group or the simple liver retraction(SLR) group. In MLR group, we used rubber tubes and 2 − 0 proleneTM creating a “Ω-shaped” appearance to retract the liver, and in SLR group, only 2 − 0 proleneTM was used. Operative and postoperative outcomes were assessed, including the values of serum liver enzymes and total bilirubin within 5 days after surgery. Results The results showed that there was no significant difference in operation time between MLR group and SLR group (317 ± 47 min vs. 318 ± 55 min, p = 0.91). Compared with SLR group, MLR group had a lower rate of liver dysfunction (serum liver enzymes or total bilirubin increased more than 2 times) after the operation (16.9% vs. 36.7%, p < 0.01), less use of the hepatoprotective drugs (4.2% vs. 17.7%, p < 0.01) and more No.7 lymph nodes. In subgroup analysis, we found that the rate of liver dysfunction was significantly different between MLR and SLR groups in distal gastrectomy (12.8% vs. 32.4%, p = 0.01). Conclusion The operation time of MLR was similar to SLR group, but the rate of liver dysfunction, and use of hepatoprotective drugs in MLR group was significantly lower than SLR group. MLR is recommended in laparoscopic gastrectomy and particularly in distal gastrectomy.
