Abstract
Objective To evaluate the clinical effect of radioclide imaging and Patent Blue V on lymphorrhea after operations in fold inguen' s space. To use radioclide imaging and Patent Blue V to prevent or cure lymphorrhea, so we can lower the incidence of lymphorrhea at the most. Methods Fourty patients undergoing operated in fold inguen' s space were randomized into tWO group : control group ( n = 20) without using radioclide imaging and Patent Blue V and treatment group (n =20) with this technology applied to the dissection area at the begin of the surgical procedure. For each group, the mean daily postoperative drainage volume, the mean cumulative drainage quantity 4 days after operation and the incidence of lymphorrhea were reported. The analysis was used to evaluate the medical effect of using radioclide imaging and Patent Blue V in surgery in fold inguen' s space. It was logical to hope that application of Radioclide imaging and Patent Blue V after operations in fold inguen' s space would reduce lymphorrhea. Results The mean daily postoperative drainage was significantly greater in control group (P 〈 0. 05 ). The mean cumulative drainage quantity 4 days after the operation was ( 125. 1 ± 23.7 ) ml and ( 369. 9 ± 31.7 ) ml in treatment group and control group respectively, the reduction of cumulative drainage was 59. 6% (P 〈 0. 05). The incidence of lyrnphorrhea was 0% (0 cases) and 10% (2 cases) in treatment group and control group respectively. (P 〈 0. 05). One wound complications (50%) occurred in patients with postoper- ative lymphorrhea, and 0 (0%) occurred in those without postoperative lymphorrhea (P 〈 0. 01 ). The total drainage duration and mean postoperative hospital stay was ( 10. 2 ± 2. 5) and ( 19. 5± 4. 5) days in lymphorrhea group, there were ( 3.5 ± 0. 8 ) and (7. 6± 1.2) days in goupe without lymphorrhea ( P 〈 0. 05). Conclusion Radioclide imaging and Patent Blue V can reduce the daily and total cumulative postoperative drainage volume, and decrease the incidence of postoperative lymphorrhea after operation in fold inguen' s space.
