  • Influence of Intraperitoneal Chemotherapy on the Healing of Rat Colonic Anastomoses

    ObjectiveTo investigate healing of rat colonic anastomoses after early postoperative intraperitoneal chemotherapy (EPIC).MethodsFortyfive Wistar rats with colonic anastomoses were divided randomly into 3 groups (15 rats each). From postoperative 1 day to 5 day, rats were injected with normal saline (NS) to the peritoneal cavity with 20 ml/(kg·d) for the NS group; 5Fu with 20 mg/(kg·d) for the 5Fu group; 5Fu with 20 mg/(kg·d) and leucovorin with 10 mg/(kg·d) for the 5Fu+LV group. On the 7th postoperative day, rats were killed and the anastomoses were evaluated whether anastomotic complications (leakage or dehiscence) occurred, the anastomotic bursting pressure (ABP) and hydroxypoline content (HPC) were measured. ResultsIn the NS group, 1 rat had incision dehiscence, another one had anastomostic leakage with but no death. In the 5Fu+LV group, 2 rats showed anastomotic leakage and 1 death. On the 7th postoperative day, the ABP in NS, 5Fu and 5Fu+LV groups were (169.1±32.6) mm Hg, (116.8±25.5) mm Hg and (154.9±31.2) mm Hg respectively; the HPC was (1.54±0.28) μg/mg, (0.9±0.33) μg/mg and (1.24±0.29) μg/mg respectively. Both the ABP and HPC, in the NS group were much significantly higher than in 5Fu group (P<0.01). Both the ABP and HPC in the 5Fu+LV group were significantly higher than which in the 5Fu group (P<0.05).ConclusionEPIC with 5Fu significantly impairs healing of the colonic anastomosis. 5Fu combined with LV for EPIC might reduce this inhibition to the process of the anastomotic healing.
