Objective:To investigate the efficacy of laparoscopic versus open hepatectomy for intrahepatic bile duct stones based on propensity score matching. Methods:This study used a case-control design to retrospectively analyze 163 patients with intrahepatic bile duct stones who were treated at The Second Hospital of Anhui Medical University between February 2014 and February 2024. Based on the surgical approach, the patients were divided into two groups: the laparoscopic hepatectomy group ( n = 72) and the open hepatectomy group ( n = 91). Using 1:1 PSM, two groups with similar baseline clinical characteristics were created to compare perioperative outcomes, stone residual rates, and recurrence rates. Results:After PSM, a total of 52 matched pairs were successfully obtained. Compared with the laparoscopic hepatectomy group, the open hepatectomy group demonstrated a significantly shorter operative time [233.00 (180.00, 315.00) minutes vs. 313.00 (222.25, 405.75) minutes, Z = 3.41, P = 0.01]. However, no statistically significant differences were observed between the open hepatectomy and laparoscopic hepatectomy groups in terms of pre- to postoperative hemoglobin change [(22.69 ± 14.27) g/L vs. (20.63 ± 14.36) g/L, t = 0.73, P = 0.465], postoperative bile leakage [5.77% (3/52) vs. 11.54% (6/52), χ2 = 1.10, P = 0.25], hypoalbuminemia [82.69% (43/52) vs. 84.62% (44/52), χ2 = 0.07, P = 0.791], pulmonary infection [28.85% (15/52) vs. 40.38% (21/52), χ2 = 1.53, P = 0.216], surgical site infection [5.77% (3/52) vs. 1.92% (1/52), χ2 = 1.04, P = 0.308], intra-abdominal infection [1.92% (1/52) vs. 5.77% (3/52), χ2 = 1.04, P = 0.308], postoperative drainage tube removal time [8.00 (6.00, 11.75) days vs. 8.00 (6.25, 10.00) days, t = 0.05, P = 0.958], postoperative hospital stay [8.00 (9.00, 15.00) days vs. 9.00 (7.00, 12.50) days, t = -1.22, P = 0.222], residual stone rate [11.54% (6/52) vs. 9.62% (5/52), χ2 = 0.10, P = 0.750], and stone recurrence rate [13.46% (7/52) vs. 3.85% (2/52), χ2 = 3.04, P = 0.081]. All differences were statistically significant (all P > 0.05). Conclusions:Laparoscopic hepatectomy and open hepatectomy have comparable efficacy in the treatment of intrahepatic bile duct stones.

Objective:To systematically evaluate the effect of physical exercises on the treatment of constipation by Meta-analysis.Methods:Randomized controlled trials of the effects of physical exercises on constipation were retrieved in databases of CNKI, WanFangData, VIP, SinoMed, PubMed, Web of Science and Cochrane Library from inception to December 2020. According to the inclusion and exclusion criteria, two reviewers independently selected literature, extracted data. The quality of included literature was evaluated by referring to the Cochrane collaboration's tool. And then the funnel plot was used to evaluate the risk of bias of included literature. Revman 5.3 software was used to conduct meta-analysis.Results:A total of 12 clinical trials include 1 004 patients were involved based on the inclusion and exclusion criteria. The physical exercise group was subjected to physical exercise or added other conventional treatment, and the control group had no regular exercise or only conventional treatment during the test. The fixed effects model was employed. The total effect of the value of the merger was calculated, the combined OR(95% CI) was 4.75(3.47, 6.51). Compared with the control group, exercise significantly relieved the patient's constipation symptoms( Z=9.69, P<0.000 01). Funnel figure shows a basic symmetry, which indicated the publication bias is small. Conclusions:Physical exercise is beneficial to constipation should be encouraged.
