Abstract:

Objective To investigate the efficacy and safety of the posterior triangle approach in laparoscopic cholecystectomy for patients with cholecystolithiasis and chronic cholecystitis. Method From January 2019 to April 2022, 120 patients with cholecystolithiasis and chronic cholecystitis who were admitted by Chuzhou Hospital of Traditional Chinese Medicine in Huai'an City were selected, all of whom received laparoscopic surgery. According to different approaches, the observation group (60 cases) and the control group (60 cases) were divided into two groups. The control group adopted the triangular approach through the gallbladder, and the observation group implemented the posterior triangular approach through the gallbladder. The clinical indicators of the two groups

were recorded and compared, Detect and analyze the difference of inflammatory level and immune function changes between the two groups before and after operation, and observe and count the total incidence of postoperative complications in each group. Result The total operation time and recovery time of patients in the observation group were shorter than those in the control group, and the intraoperative bleeding was less than that in the control group (P ＜ 0.05). At 72h after operation, the TNF-α and IL-6 levels in the observation group were lower than those in the control group, and the percentage of CD4+and CD8+T cells were higher than those in the control group (P ＜ 0.05). Conclusion Laparoscopic cholecystolithiasis with chronic cholecystitis can be performed by the posterior triangle approach, which can effectively reduce the inflammatory reaction caused by surgery, and has less postoperative complications and high safety.
