Curative effect of improved loop electrosurgical excision procedure for diagnosis and treatment of cervical diseases / 中国医师杂志

ABSTRACT

Objective To study the effect of using improved loop electrosurgical excision procedure for diagnosis and treatment of cervical diseases. Methods The clinical data of 70 cases of cervical intraepithelial neoplasia or carcinoma in situ from January 2006 to Decemder 2008 in our hospital was collected.The operation time, the mean volume of blooding, days of blooding, relationship between the mean blood and areas of pyramid area of pyramid was compared between study group and control group. Improved loop electrosurgical excision procedure was executed on 21 cases of study group ( CIN Ⅰ 4 cases, CIN Ⅱ 10 cases,CIN Ⅲ4 cases, CIS3 cases ) and loop electrosurgical excision procedure was used on 49 cases in control group (CIN Ⅰ7 cases,CIN Ⅱ21 cases, CIN Ⅲ 16 cases, CIS5 cases). Results Blood loss [(16.57 ±17. 47 ) ml], operative time [( 9.07 ± 3.34 ) min] and postoperative bleeding time [(9.10 ± 2.23) d] in study group were lower than that in control group [( 39.80 ± 37.43 ) ml, ( 12. 19 ± 5.34 ) min, ( 10. 49 ±2. 76)d], and the differences were statistically significant ( P < 0. 05 ). Cervical cone volume [( 14. 70 ±13. 35 ) mm3] and blood loss [(32. 83 ± 14. 32 ) ml] were positively correlated ( r = 0. 430, P < 0. 05 ). No significant difference between prognosis of two groups was found( P >0. 05 ). Conclusion There was positive relationship between the averge blood loss in surgery and areas of pyramid excision. It'd be better to stitch the ramus descendents of uterine artery at three and nine o'clock of the cervix uteri, when the patients were expected to have large pyramid areas and abundant blood flow who may bleed more than normal. which can reduce the blood loss after surgery and reduce the time of surgery.
