Clinical advantages of absorbable barbed wires in laparoscopy combined with choledochoscopy treatment of gallbladder polyps / 中国基层医药

Objective:To investigate the clinical advantages of absorbable barbed wires in laparoscopy combined with choledochoscopy treatment of gallbladder polyps.Methods:The clinical data of 103 patients with gallbladder polyps who received laparoscopy combined with choledochoscopy treatment in The First People's Hospital of Lianyungang from February 2016 to March 2018 were retrospectively analyzed. Sixty-five patients in the observation group underwent gallbladder wall sutures with absorbable barbed wires, and thirty-eight patients in the control group underwent gallbladder wall sutures with common absorbable wires. The operative time, gallbladder wall suture time, intraoperative blood loss, average hospitalization time, and postoperative bile leakage were compared between the two groups.Results:There were no significant differences in intraoperative blood loss and average hospitalization time between the two groups ( P = 0.312, P = 0.114). In the observation group, gallbladder wall suture time and operative time were (5.58 ± 1.14) minutes and (60.71 ± 11.03) minutes, respectively, which were shorter than (6.32 ± 1.04) minutes and (68.24 ± 9.61) minutes in the control group ( t = 3.23, 3.50, P = 0.002, 0.001). No bile leakage occurred in the observation group and bile leakage occurred in four (10.5%) patients in the control group. There was a significant difference in bile leakage between the observation and control groups ( χ2 = 4.57, P = 0.032). Conclusion:Absorbable barbed wires for gallbladder wall sutures during operation in laparoscopy combined with choledochoscopy treatment of gallbladder polyps is safe and feasible. It can markedly shorten gallbladder wall suture time and operative time, decrease the incidence of bile leakage, and has a clinical advantage over common absorbable wires.

Analysis of serological and genetic test results of rare Ax14 subtypes in a young child / 中国输血杂志

Objectives To identify ABO blood type from a child having discrepant results in forward and reverse ABO blood grouping by serological identification and genetic testing.Methods After routine serological detection with ABO blood group,the ABO gene and ABO blood group-A subgroup genotype were tested by PCR-SSP method.Results The Serological results showed that the specimen was positive type A (anti-A:1 +w),the reverse type is O type (Ac:2 +,Bc:4 +);PCRSSP A-subtype typing showed that the genotype of the child was Ax14/O2.Conclusion Difficult blood type identification sometimes need to combine serology and molecular biology methods to confirm.In this case,the phenotype of the child was Ax,and the genotype was Ax14/O2.
