Resumen
- Background Paclitaxel has been used frequently for Hyperthermic Intraperitoneal Chemotherapy (HIPEC) for ovarian carcinomatosis. Cytoreductive surgery and HIPEC are associated with high rates of morbidity being anastomotic dehiscence one of the most frequent. The objective of this study is to quantify the effect of Paclitaxel-based HIPEC on colonic anastomosis in an experimental rat model.
  
  Methods After left colon resection and anastomosis, animals were randomized into four groups: Controls (C); Hyperthermia (H); Normothermic Intraperitoneal Paclitaxel (CP) and Paclitaxel-based HIPEC (HP). On postoperative day four, animals’ peritoneal cavities were examined macroscopically, colon anastomosis burst pressures measured and specimens analyzed histologically.
  
  Results Thirty-nine animals were randomized and 36 were included in the analysis. H group presented the highest burst pressure 105.11 ± 22.9 mmHg, which was 27% higher than C (77.89 ± 27.6 mmHg). On the other hand, HP presented the lowest burst pressure 64 ± 26 mmHg, 16% lower than C group and 39% lower than H, being this latter difference statistically significant (p = 0.004). There were no significant differences regarding weight loss, adhesion scores, perianastomotic abscesses and histological findings (inflammation, fibroblasts, neoangiogenesis, and collagen among groups).
  
  Conclusion Strength of colonic anastomosis was improved by isolated hyperthermia and negatively affected by Paclitaxel-based HIPEC.
