Comparative study of simultaneous three scopes surgery and staged two scopes surgery in the treatment of choledocholithiasis with cholecystolithiasis / 国际外科学杂志

ABSTRACT

Objective:To compare the clinical efficacy of the Simultaneous three scopes combined surgery [laparoscopic cholecystectomy(LC)+ choledochoscopy exploration + choledochectomy and removal of the common bile duct + primary suture of the common bile duct + endoscopic guided nasobiliary duct placement] and staged two scopes surgery[endoscopic retrograde cholangiopancreatography (ERCP) combined with LC] in the treatment of choledocholithiasis and cholecystolithiasis.Methods:From January 2018 to June 2020, we retrospectively analyzed the clinical data of 83 patients with choledocholithiasis and choledocholithiasis, who underwent minimally invasive treatment in our center. According to the different surgical procedures, the patients were divided into three-mirror group ( n=42) and two-mirror group ( n=41). All patients in the three-mirror group underwent three-scopy combined surgery. The patients in two-mirror group received endoscopic retrograde cholangiopancreatography (ERCP) combined with laparoscopic cholecystectomy (LC). In this study we compared the relevant clinical indicators of the two groups, in terms of the operation time, intraoperative blood loss, one-time stone clearance rate, postoperative exhaust time, postoperative defecation time, total hospitalization cost, incidence of postoperative acute pancreatitis, postoperative stone recurrence rate, incidence of postoperative cholangitis, and incidence of postoperative biliary fistula, total hospitalization time, postoperative bile duct stricture rate. Use SPSS 26.0 software to statistically analyze various indexes such as intraoperative, postoperative, follow-up, etc. Normally distributed measurement data were described by the mean±standard deviation ( Mean± SD), the comparison between groups was by t test, and measurement data with skewed distribution were destribed as M( P25, P75), Pairwise comparisons were analyzed using nonparametric test. The comparison of count data between groups was by the chi-square test. Results:No death was observed in both two groups. The operation time, intraoperative blood loss, one-time stone clearance rate, postoperative exhaust time, and postoperative defecation time of the three-mirror groupwere (167.98±47.37) min, 50(50, 100) mL, 100%(42/42), (2.10±0.76) days, 3(3, 4) days, the two-mirror group were (143.80±34.47) min, 50(50, 50) mL, 85.4%(35/41), (1.53±0.99) days and 2(1, 3) days. Compared with the two groups, the three-mirror group was higher than the two-mirror group, and the difference was statistically significant ( P<0.05). The total hospitalization expenses, postoperative acute pancreatitis incidence, and postoperative calculus recurrence rate in the three-mirror group were (3.46±0.77) ten thousand yuan, 0(0/42), 2.38%(1/42), the two-mirror group were (4.22±1.50) ten thousand yuan, 9.8%(4/41), 19.5%(8/41). Compared with the two groups, the three-mirror group was lower than the two-mirror group, and the difference was statistically significant ( P<0.05). No postoperative cholangitis or biliary fistula occurred in the two groups. There was no statistically significant difference in the total hospital stay and incidence of postoperative bile duct stenosis between the two groups ( P>0.05). Conclusions:For choledocholithiasis combined with cholecystolithiasis patients, simultaneous three-scopes combined surgery and elective LC after ERCP are safe and effective, and each has its own advantages. It should be selected reasonably according to the patient′s condition and combined with the technical advantages of the treatment team.
