- Abstract: Objective To explore the feasibility of using the left inferior phrenic vein as an anatomical landmark and prioritizing the dissection of the central adrenal vein in retroperitoneal laparoscopic left adrenalectomy(RLLA).Methods 116 patients who had RLLA carried out in our hospital between January 2021 and December 2023 were chosen.They were separated into the experimental group(RLLA with the left inferior phrenic vein as an anatomical landmark and prioritizing the dissection of the central adrenal vein)and the control group[conventional three-layer method anatomic retroperitoneal laparoscopic adrenalectomy(RLA)],with 58 cases in each group.The clinical data of the two groups were compared,and the intraoperative and postoperative 24 h clinical indicators,stress indicators,immune function,and complications were evaluated.Results RLLA was successfully completed in two groups,and no cases were converted to open surgery.The operation time,time for searching the central vein,retention time of the drainage tube and postoperative hospital stay in the experimental group were significantly shorter than those in the control group.The intraoperative blood loss and postoperative drainage volume were significantly less than those in the control group,the differences were all statistically significant(P<0.05);There was no statistically significant difference in the recovery time of gastrointestinal function between the two groups of patients after surgery(P>0.05).There were no statistically significant differences in preoperative inflammatory factors,stress indicators and immune function indicators between the two groups of patients(P>0.05).The white blood cell(WBC),C-reaction protein(CRP)and interleukin-6(IL-6)of the two groups of patients 24 hours after the operation were significantly higher than those before the operation,but the experimental group was significantly lower than the control group,the differences were statistically significant(P<0.05).The malondialdehyde(MDA)of the two groups of patients 24 hours after the operation was significantly higher than that before the operation,while the superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px)were significantly lower than those before the operation,and the MDA in the experimental group was significantly lower than that in the control group,and the SOD and GSH-Px were significantly higher than those in the control group(P<0.05).The levels of CD4+and CD4+/CD8+in experimental groups of patients 24 hours after the operation were significantly decreased than those before the operation,and the levels of CD3+,CD4+and CD4+/CD8+in the experimental group were significantly higher than those in the control group.The differences were statistically significant(P<0.05).There was no statistically significant difference in CD8+between the two groups of patients 24 hours after surgery(P>0.05).The number of cases with intraoperative blood pressure fluctuations in the experimental group was significantly lower than that in the control group,the difference was statistically significant(P<0.05).Neither peritoneal injury,renal pedicle vascular injury or retroperitoneal hematoma occurred during or after the operation in the two groups of patients.Conclusion In RLLA,using the left inferior phrenic vein as an anatomical landmark and prioritizing the dissection of the central adrenal vein is feasible,which can improve surgical indicators,reduce stress response and immune response,and have clinical application value.
