Does Epidural Anesthesia Reduce Postoperative Ileus Following Colorectal Surgery?

Overview

The use of epidural analgesia (EA) has been suggested as an integral part of an enhanced recovery program for colorectal surgery. However, the effects of EA on postoperative ileus remain controversial. Some authors suggest that EA has beneficial effects for postoperative outcome and hospital stay, whereas others have reported that the role of EA in the modern perioperative care of patients undergoing open colorectal surgery has been limited. Therefore, the investigators aimed to investigate the effect of EA on postoperative outcome, particularly postoperative ileus and hospital stay in patients with colorectal surgery.

Detailed Description

In 2016, results of Cochrane review of 22 trials on the efficacy of EA in patients undergoing abdominal surgery showed that an epidural containing a local anesthetic, with or without the addition of an opioid, accelerated the return of gastrointestinal transit (high quality of evidence) and no difference in the incidence of vomiting or anastomotic leak (low quality of evidence). For open surgery, an epidural containing a local anaesthetic would reduce the length of hospital stay (very low quality of evidence). However, in a recent analysis from American College of Surgeons revealed that the use of EA did not improve postoperative recovery after elective colectomy in their analysis and was associated with increased postoperative ileus and prolonged hospital stay after open colectomy. In this study, the investigators aimed to compare the efficacy of EA to reduce the postoperative ileus and hospital stay, as well in the patients undergoing colorectal surgery. This prospective randomized study planned to include 100 consecutive patients with colorectal disorders.

Interventions

  • Procedure: epidural anesthesia
    • epidural anesthesia through epidural injection of a local anaesthetic combined with an opioid

Arms, Groups and Cohorts

  • Other: EA group
    • patients with colorectal surgery that willl be performed epidural anesthesia
  • No Intervention: non -EA group
    • patients with colorectal surgery that willl be performed only general anesthesia

Clinical Trial Outcome Measures

Primary Measures

  • postoperative ileus
    • Time Frame: up to 4 days
    • obstipation and intolerance of oral intake due to nonmechanical factors that disrupt propulsive activity of the gastrointestinal system following colorectal surgery..Obstipation was defined as abdominal distention or/and pain at physical examination and difficulty passing gas postoperatively. Intolerance of oral intake was defined as nause or vomiting associated with food intake
  • prolonged postoperative ileus
    • Time Frame: up to 10 days
    • inability to tolerate oral intake, two or more of nause/ vomiting requiring cessation of oral diet or/and nasogastric decompression and intravenous support, and absence of flatus prolonging hospitalization beyond discharge goal..Prolonged PO was defined as by the postoperative day 5, in case of persistent symptoms mentioned above and radiological confirmation of ileus on plain abdominal film showing multiple distended loops with air and/or fluid and air in both small intestines and large intestines.

Secondary Measures

  • hospital stay
    • Time Frame: up to 1 year
    • time from the day of surgery to day of discharge
