EP.TU.582Impact of enteral prophylactic antibiotic course on the trends of inflammatory markers following laparoscopic colorectal cancer surgery

Abstract Introduction The study aimed to assess the effect of oral prophylactic antibiotic (OAB) with mechanical bowel preparation (MBP) on the serial measurement of postoperative inflammatory markers and clinical outcomes of the patients undergoing laparoscopic colorectal cancer resection surgery. Methods A retrospective data collection was carried out from January 2019 to March 2020 for the patients undergoing laparoscopic colorectal cancer resection. Daily measurements of inflammatory markers were obtained upto 7 days following surgery. The measurements of inflammatory markers were compared between patients who received a 1 week course of OAB along with MBP to those who only received MBP. Results There were a total of 110 patients that were divided into 2 groups: patients who received OAB and MBP (n = 44, 40%) and those who had MBP only (n = 66, 60%). There was no significant difference between the patient characteristics and preoperative staging of the cancer between the 2 groups. The overall length of stay was significantly lower in the patients who received OAB (9.09 days [SD 7.94] vs. 6.63 days [SD 4.96], P 0.02). The patients with OAB and MAP had persistently and significantly low levels of white blood cell count, CRP, and neutrophil count throughout the postoperative period as compared to those who only had MBP. Conclusion The study demonstrated reduction in serial measurement of inflammatory markers throughout postoperative stay for the patients receiving preoperative OAB. The use of OAB helps in physiological recovery of the patient by reducing the inflammatory process postoperatively.

Laparoscopic Colorectal Cancer Resection

Abstract Introduction Laparoscopic colorectal cancer resection (LCCS) has been shown to reduce blood loss when compared to open surgery. There are no national guidelines regarding need for pre-operative group and save(G&S) sampling in LCCS patients. Our study aims to assess the necessity of G&S samples through identifying rates of post-operative transfusion following LCCS. Methods Retrospective study of all patients who underwent LCCS between 1st January 2019 and 31st December 2019. Results Of 102 surgical procedures, 42 right hemicolectomy, 21 anterior resection, 19 sigmoid colectomy, 12 left hemicolectomy, and 8 APER. The median age was 67(range 56-86) years. All received two valid G&S samples. 13 cases were converted. The median pre-operative haemoglobin was 127g/L, and median post-operative haemoglobin was 114g/L. The median blood loss was <100mls. Only 4(3.9%) patients required post-operative transfusion, 3 of whom were converted due to intra-operative bleeding. The fourth case had decreased haemoglobin post-operatively without need for return to theatre. A significant difference was evident in pre-operative haemoglobin level in patients who needed transfusion compared to those who did not (P = 0.031). A total of 9 units were transfused. Twenty-one pre-operative cross-matched units were not used. Conclusion Evidently, blood transfusion is most likely required in open conversion cases due to intra-operative blood loss, as well as in patients with low pre-operative haemoglobin. A patient specific approach to assessing requirement for pre-operative G&S in elective LCCS patients is required to improve cost-effectiveness, particularly taking into account those with normal pre-operative haemoglobin.
