ABSTRACT
Objective To study the influence of different suture methods on the uterine diverticulum without suture of subcutaneous fat in cesarean section .Methods 106 cases of cesarean section were randomly divided into two groups according to the digital chart ,53 cases in each group .The control group received single layer suture in cesarean section without suture of subcutaneous fat ,while the observation group received double suture with cesarean section without suture of subcutaneous fat .The incision adverse reactions were observed in the two groups .After 1 year of follow-up,the scar diverticulum in the incision of the uterus was observed .Results In the control group,1 case, 13 cases,9 cases and 0 cases were found fat liquefaction ,subcutaneous induration ,incision redness and swelling ,and the incision union was bad.The incidence rate of adverse reaction was 43.4％.In the observation group,the fat lique-faction,subcutaneous induration ,incision redness and swelling ,incision union were 0 case,2 cases,3 cases,0 case,the incidence rate of adverse reactions was 9.4％.The side effects of incision in the observation group were significantly less than those in the control group(χ2 =13.620,P<0.01).After follow-up for 1 year,the number of diverticula, the muscularis of the diverticulum and the volume of the diverticulum in the control group were 6 cases,(5.51 ± 2.01)mm,(0.46 ±0.13)mL,which in the observation group were 2 cases,(7.63 ±1.63)mm,and (0.31 ±0.11)mL. The incidence of diverticularization in the observation group was significantly less than that in the control group (χ2 =8.960,P<0.05).The diverticulum muscle thickness of the observation group was significantly higher than that of the control group(t=4.631,P<0.05).The diverticulum volume of the observation group was significantly less than that of the control group(t=2.914,P<0.05).Conclusion Cesarean section incision without suture subcutaneous fat bilayer suture is more conducive to the healing of the incision , the formation of scar diverticulum less chance , the formation of scar diverticulum degree is light .
