摘要

Purpose

Early recovery from intestinal dysfunction after surgery reduces the risk of complications. In this study, we used radiopaque markers (SITZ MARKS® [SM] ) to objectively evaluate intestinal motility and identify the factors that hinder intestinal motility recovery.

Methods

We included patients who underwent elective colon cancer surgery between January 2009 and December 2014. The exclusion criteria were as follows: (i) more than two anastomoses; (ii) intestinal obstruction; (iii) having undergone colostomy or ileostomy; (iv) having undergone additional resection of other organs; and (v) admission to the intensive care unit after surgery. All patients ingested SM 2 h before surgery. We assessed the residual number of SM to evaluate postoperative intestinal motility. We defined a delayed recovery as the presence of residual SM in the small intestine 3 days after surgery. We used a multivariate analysis to extract the factors associated with a delayed recovery of intestinal motility.

Results

Three hundred and thirty-seven patients were included. Mechanical bowel preparation (MBP) with polyethylene glycol (odds ratio [OR]: 2.6, P < 0.001), open surgery (odds ratio [OR]: 1.8, P = 0.048), and excessive intraoperative fluid administration (> 10 mL/kg/hour) (odds ratio [OR]: 1.8, P = 0.009) were significant factors for a delayed recovery of intestinal motility.

Conclusion

The omission of MBP, laparoscopic surgery, and appropriate intraoperative fluid administration can facilitate an early recovery of intestinal motility.
