ObjectiveTo explore the effect of preoperative jaundice on the complications of laparoscopic cholecystectomy combined with intraoperative biliary stone removal in patients with common bile duct stones.MethodsA total of 104 patients with choledocholithiasis who underwent laparoscopic cholecystectomy combined with intraoperative biliary stone removal for common bile duct stones in Baishui County Hospital and No.215 Hospital of Shaanxi Nuclear Industry between January 2014 and February 2016 were enrolled and retrospectively analyzed. The patients were divided into the jaundice group (43 cases) and the jaundice-free control group (control group, 61 cases) according to the preoperative serum total bilirubin level. The differences in postoperative complication rates between the two groups were compared and risk factors affecting postoperative complications were explored.ResultsThe ALT and total bilirubin on the first day after operation in the jaundice group were higher than those in the control group (P<0.05). In addition, the hospital stay in the jaundice group was shorter than that of the control group (P<0.001). There was no significant difference in the incidence of total postoperative complication rate and the incidence of complications (included biliary leakage, ballistic hemorrhage, hyperthermia, incision complications, and other complications) between the two groups (P>0.05). There were no significant differences in Clavien-Dindo classification, comprehensive complication index (CCI), and ratio of CCI≥20 (P>0.05). Multivariate analysis showed that male and residual stones were independently associated with postoperative complications (P<0.05), but there was no statistical correlation between preoperative jaundice and postoperative complications (P>0.05).ConclusionPreoperative jaundice does not increase the risk of complications after acute laparoscopic surgery in patients with common bile duct stones.
Objective To compare the short-term result between the high-flex (HF) and conventional posteriorstabil ized (PS) prosthesis in total knee arthroplasty (TKA). Methods From April 2005 to October 2007, 23 cases (27 knees) underwent TKA by HF prosthesis (HF group), and 35 cases (41 knees) underwent TKA by PS prosthesis (PS group).In HF group, there were 2 males (3 knees) and 21 females (24 knees) aged (64.3 ± 5.6) years, including 20 cases (23 knees) of osteoarthritis and 3 cases (4 knees) of rheumatoid arthritis; body mass index (BMI) was 27.3 ± 3.9; the course of disease was (5.3 ± 5.6) years; the Hospital for Special Surgery Scoring System (HSS) score was 58.4 ± 7.9; the Western Ontario and McMaster universities osteoarthritis index (WOMAC) score was 49.4 ± 6.9; the maximum knee flex degree was (107.6 ± 8.3)°; and the range of knee motion was (103.5 ± 7.7)°. In PS group, there were 3 males (3 knees) and 32 females (38 knees) aged (65.1 ± 5.9) years, including 33 cases (39 knees) of osteoarthritis and 2 cases (2 knees) of rheumatoid arthritis; BMI was 27.1 ± 4.1; the course of disease was (5.1 ± 4.9) years; HSS score was 60.1 ± 10.4; WOMAC score was 47.9 ± 7.2; the maximum knee flex degree was (108.4 ± 9.7)°; and the range of knee motion was (105.9 ± 11.4)°. There were no significant differences in general data between two groups (P gt; 0.05). Results All incisions achieved heal ing by first intention. No compl ication of ankylosis, blood vessel and nerve injuries, and prosthesis loosening occurred. All patients were followed up for 24-54 months (average 32.8 months). There were no significant differences in the HSS score, WOMAC score, the maximum knee flex degrees, and the range of knee motion at 3, 12, and 24 months after operation between two groups (P gt; 0.05), but there were significant differencesbetween pre- and post-operation (P lt; 0.05). Anterior knee pain occurred in 1 case of HF group and 4 cases of PS group after 24 months, the incidence rates were 3.70% in HF group and 9.76% in PS group, showing significant difference (P lt; 0.05). The X-ray films showed that no lucent zone around prosthesis and no patella baja were observed, and the force l ine was excellent. Conclusion There is no significant difference in the range of knee motion and cl inical scores between the HF prosthesis and the PS prosthesis, but the former’s incidence rate of anterior knee pain is lower.
