Does epidural anesthesia and analgesia really improves surgical outcome after colorectal cancer surgery

Lithuanian Cancer Register has registered 1443 new cases of colorectal cancer in 2004 and this value constantly increases about 200 cases per year 1. Colorectal cancer is on the third place among all cancer patients in our country. Colorectal cancer surgery is associated with a major surgical trauma. Majority of recent randomized clinical trials (RCT) has shown that combined general - epidural anesthesia and postoperative epidural analgesia has demonstrated some beneficial effects and improved surgical outcome in various fields of surgery 2-4. However controversies still exist about epidural anesthesia and analgesia effects on colorectal anastomosis and it?s influence on patients? outcome.

TÓM TẮT Đặt vấn đề: Gây tê ngoài màng cứng để giảm đau trong và sau mổ được áp dụng rộng rãi trên thế giới từ nhiều thập niên qua. Kết quả của nhiều công trình nghiên cứu cho thấy phương pháp này làm giảm những biến chứng trong và sau mổ, giảm tỉ lệ tử vong sau mổ của các phẫu thuật nặng. Nghiên cứu nhằm đánh giá hiệu quả và các tác dụng phụ của gây tê ngoài màng cứng trong phẫu thuật ung thư đại, trực tràng. Phương pháp: Nghiên cứu mô tả cắt ngang trên 28 bệnh nhân được gây tê ngoài màng cứng trong mổ ung thư đại, trực tràng có phối hợp gây mê nội khí quản. Sinh hiệu và tình trạng sức khỏe của bệnh nhân được theo dõi trước và sau khi tiêm thuốc giảm đau. Ghi nhận mức độ giảm đau theo Visual Analog Scale (VAS), mức độ liệt vận động theo Bromage và các tác dụng phụ sau mổ. Kết quả: Hiệu quả giảm đau sau mổ tốt, tại các thời điểm sau mổ VAS đều ≤ 1,5. Tỉ lệ các biến chứng: tụt huyết áp: 7,14%, đau đầu: 7,14%, lạnh run: 10,71%, buồn nôn, nôn: 17,86%. Kết luận: Kỹ thuật gây tê ngoài màng cứng phối hợp với gây mê toàn thân là kỹ thuật giảm đau hiệu quả và an toàn cho phẫu thuật vùng bụng trong mổ và 24 giờ sau mổ. ABSTRACT THE EFFICIENCY OF SPINAL EPIDURAL ANESTHESIA FOR LAPAROSCOPIC COLORECTAL CANCER SURGERY Background: Epidural anesthesia for pain relief during and after surgery has been widely applied in the world for decades. The results of many studies show that this method reduces intra - and postoperative complications and reduces the postoperative mortality rate of major surgery. The study aimed to evaluate epidural anesthesia’s effectiveness and side effects in colorectal cancer surgery. Methods: A cross - sectional descriptive study on 28 patients receiving epidural anesthesia in surgery for colorectal cancer in combination with endotracheal anesthesia. The patient’s vital signs and health status were monitored before and after the injection of pain medication. Record the level of pain relief according to the Visual Analog Scale (VAS), the degree of motor paralysis according to Bromage, and the side effects after surgery. Results: Good postoperative pain relief effect, at all times after surgery, VAS was ≤ 1.5. Rate of complications: hypotension: 7.14%, headache: 7.14%, shiver: 10.71%, nausea, vomiting: 17.86%. Conclusion: The epidural anesthesia combined with general anesthesia is an effective and safe analgesia technique for abdominal surgery during surgery and 24 hours after surgery.

Abstract Background Colorectal surgery is associated with a high incidence of postoperative infections. Early clinical signs are difficult to distinguish from the systemic inflammatory response related to surgical trauma. Timely diagnosis may significantly improve the outcome. The objective of this study was to compare a new biomarker index CD64 for neutrophils (iCD64n) with standard biomarkers, white blood cell (WBC) count, neutrophil/lymphocyte ratio (NLR), C-reactive protein (CRP) and procalcitonin (PCT) for the early detection of postoperative infection. Methods The prospective study included 200 consecutive patients with elective colorectal cancer surgery. Postoperative values of biomarkers from the postoperative day (POD) 1 to POD5 were analysed by the receiver operating characteristic (ROC) analysis to predict infection. The Cox regression model and the Kaplan-Meier method were used to assess prognostic factors and survival. Results The increase of index CD64n (iCD64n) after surgery, expressed as the ratio iCD64n after/before surgery was a better predictor of infection than its absolute value. The best 30-day predictors of all infections were CRP on POD4 (AUC 0.72, 99% CI 0.61–0.83) and NLR on POD5 (AUC 0.69, 99% CI 0.57–0.80). The best 15-day predictors of organ/ space surgical site infection (SSI) were the ratio iCD64n on POD1 (AUC 0.72, 99% CI 0.58–0.86), POD3 (AUC 0.73, 99% CI 0.59–0.87) and CRP on POD3 (AUC 0.72, 99% CI 0.57–0.86), POD4 (AUC 0.79, 99% CI 0.64–0.93). In a multivariate analysis independent risk factors for infections were duration of surgery and perioperative transfusion while the infection itself was identified as a risk factor for a worse long-term survival. Conclusions The ratio iCD64n on POD1 is the best early predictor of intra-abdominal infection after colorectal cancer surgery. CRP predicts the infection with the same predictive value on POD3.
