Analysis Of Influencing Factors Of Postoperative Drainage Volume After Four Kinds Of Methods To Resect Sacral Tumors

Objective:To explore the effect of operating method of sacral tumors, tumorous types and divisions on the postoperative drainage volume.Methods:①Retrospective analysis of surgical treatment of 86 cases of sacral tumors with clinical data who were in hospital from 3.1990～2009.9, according to intraoperative bleeding mode of control, they were divided into 4 groups:no-vessel controlled bleeding in 31 cases (Group A), preoperative embolization of target vessel intervention in 11 cases (Group B), internal iliac artery ligation in 21cases(Group C), intermittent block of lower abdominal aorta in 23cases(Group D).②Compare each group's drainage volume of postoperative 12h,24h,48h, and extubated time of cumulative drainage volume, time of drainage-tube placed, hospital stay after surgery, the first review of postoperative routine blood test RBC,HB,HCT indicators, postoperative wound infection, delayed healing of incidence rate of complications.③Compare drainage volume of Chordoma, Giant cell tumor and different divisions.Result:㈠①The total drainage volume of Group A is statistically different as comparison of each other(P<0.05).②The each time drainage volume of Group B is the most, which is significant difference with others(P<0.05).③The total drainage volume of Group C and D are no significant difference (P> 0.05).㈡The cumulative drainage volume of Giant cell tumor and Chordoma exist significant difference (P<0.05), drainage volume of Giant cell tumor is more than Chordoma.㈢①Drainage volume of Chordoma (I+II division) are the most,drainage volume of Chordoma (II division) are the least (P<0.05).②Drainage volume of Giant cell tumor I and II division have no significant difference in drainage volume (P= 0.16> 0.05); Drainage volume of Giant cell tumor (I+II division) are the most.㈣The accumulated drainage volume decrease after postoperative 12h, the drainage volume of postoperative 12h accounts for 38.7% of the total,12h shows the peak period.㈤The time of drainage-tube placed:Group A have statistically significant difference comparing with each groups(P<0.05), which is the shortest. Other groups show no significant difference (P> 0.05).㈥Postoperative hospital stay of Group D have statistically significant difference (P<0.05) comparing with other groups, which is the shortest, and other groups showed no significant difference (P> 0.05).㈦The first review of routine blood test:RBC exists no significant difference with each other (P> 0.05);HB, HCT of Group A exist statistically significant difference with other groups (P<0.05),Group B,C,D have no statistically significant difference (P> 0.05).㈧The total drainage volume, time of drainage-tube placed have no significant effect to the complications (P> 0.05).㈨①The complications of Group A,B,C and D are carried on chi-square test, which exist significant difference (P<0.05), according to rank second to further infer, Group D is the least.②Complications of Group A,B and C have no significant difference.Conclusion:Operating methods,tumorous types and divisions are the factors of affecting the drainage volume. Preoperative embolization of target vessel intervention has the most drainage volume, no-vessel controlled bleeding is the least. The drainage volume of Giant cell tumor is more than Chordoma, sacral tumor of high post is greater than low post.
