Impact of increasing intra-abdominal pressure on digestive system during colorectal cancer patients under minimally invasive surgical procedure / 中国内镜杂志

ABSTRACT

Objective To investigate the impact of intraoperative intra-abdominal pressure increasing on digestive system.Methods A retrospective analysis of clinical data of 132 cases of colorectal cancer patients from January 2013 to June 2016 was made. Patients were divided into groups A, B and C according to the intra-abdominal pressure, 46 cases in each group. Group A: 46 patients, 10 mmHg (1 mmHg = 0.133 kPa), group B: 45 patients, 12 mmHg, group C: 41 patients, 15mmHg. Comparison of postoperative recovery time, complications, serum cytokine levels was made among the three groups.ResultsThe number of postoperative 6h nasogastric tube pulled out, bowel recovery time, ifrst lfatus or a bowel movement, tolerance semi-liquid diet, postoperative duration of diarrhea, postoperative hospitalization time among the three groups show no statistically difference (P > 0.05). The difference of acute gastric injury (AGI), chyle leakage, anastomotic fistula, surgical bleeding, intestinal paralysis, vomiting incidence of postoperative among the three groups has no statistically differences (P > 0.05). While postoperative IL-6 level and MAP were signiifcantly increased compare with preoperative level, the difference was statistically signiifcant (P 0.05). Postoperative serum IL-6 levels in 25 patients with intestinal paralysis was (10.71 ± 4.37) ng/L, 107 cases had high serum IL-6 levels in patients did not occur intestinal paralysis was (10.66 ± 4.13) ng/L, the difference was not statistically significance (P > 0.05).Conclusion Intra-abdominal pressure increasing during minimally invasive surgical procedure has no signiifcant effect on the digestive system in colorectal cancer patients.
