Abstract:

Objective This study aims to investigate the valueof a new type of self⁃shedding stent in lapa⁃ roscopic common bile duct exploration（LCBDE）with primary suture. Methods From January 2019 to December 2020，98 cases with common bile duct stones underwent LCBDE in our hospital were retrospectively enrolled. They were divided into experimental group（n = 51，new self⁃shedding stent with primary suture）and control group （n = 47，T tube drainage）. The general information，Operation time，blood loss，indwelling time of biliary drainage tube，indwelling time of abdominal drainage tube，anal exhaust time，length of hospital stay，hospitalization costs and postoperative complications were compared between the two groups. Results There were no significance in general information，operation time［（122.84 ± 6.47）min vs.（120.57 ± 9.98）min］，blood loss［（25.14 ± 3.97）mL vs.（24.21 ± 2.30）mL］and anal exhaust time［（2.86 ± 0.72）d vs.（3.12 ± 0.82）d］between the two groups （P > 0.05）. The experimental group showed shorter indwelling time of biliary drainage tube［（14.45 ± 2.90）d vs. （31.47 ± 1.84）d］，indwelling time of abdominal drainage tube［（3.33 ± 0.77）d vs.（6.12 ± 0.85）d］and length of hospital stay［（4.80 ± 0.80）d vs.（7.17 ± 0.70）d］，fewer hospitalization costs［（11 954.47 ± 1 098.00）yuan vs. （13 419.64 ± 1 470.90）yuan］and lower postoperative complications（2.00% vs. 14.90%）compared with control group，with a statistically significant difference（P < 0.05）. Conclusion The placement of a newself ⁃ dropping stent in LCBDE can reduce indwellingtime of biliary drainage tube and abdominal drainage tube，with shorter length of hospital stay，fewer hospitalization costs，and lower postoperative complications compared with T tube under a premise of strict indication，it′s a safe and valuable operation.
