About this study
Official title: Efficacy of Simo Decoction and Acupuncture or Chewing Gum Alone on Postoperative Ileus in Colorectal Cancer Resection: a Randomized Clinical Trial
Colorectal cancer resection is one of the most common types of abdominal surgery. Though most patients undergoing colorectal resection show recovery of bowel movements within a week, some have prolonged intestinal paralysis or postoperative ileus, resulting in decreasing patient comfort, increasing morbidity and mortality, a longer hospital stay and subsequent increased healthcare costs.
Read the detailed description
Prevention the incidence of postoperative ileus (POI) is quite important because of the negative clinical outcomes it causes. In the past two decades, many treatments and care approaches, such as fluid restriction, early enteral nutrition, and nonsteroidal anti-inflammatory drug are used for the management of POI. In theory of traditional Chinese medicine, oral simo decoction (SMD) or acupuncture at the tsusanli acupoint can boost gastrointestinal hypomotility. The efficacy of accelerating the return of gastrointestinal function by such single method or combination of them has been validated in randomized controlled trials and systematic review following several types of surgery. In recent years, chewing gum, a new and simple modality, has become a commonly applied method in order to prevent and reduce the POI. Systematic reviews and meta-analyses revealed that chewing gum provided significant benefits for the improvement of postoperative bowel function. More importantly, many official guidelines recommend chewing gum for an evidence-based approach in the prevention of POI. Despite these positive evidence, three newest randomized controlled trials are unable to demonstrate an effect of chewing gum on the recovery of bowel function after colorectal resection.
It is important to note that almost all previous randomized controlled trials are based on small sample size. This raises the question whether postoperative SMD, acupuncture at the tsusanli acupoint, or chewing gum can reduce risk of POI following colorectal resection among patients with large sample size. To examine this question, we conducted this randomized controlled trial to compare incidence of POI and length of hospital stay in colorectal cancer patients who received SMD and acupuncture, chewing gum or no intervention following resection.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
simo decoctionDietary supplement
Participants allocated to SMD and acupuncture were asked to take oral SMD decoction (Hansen Co., Ltd., Yiyang, Hunan province, China, 10 mL/dose) three times per day beginning on the first day after colorectal resection. They also received bilateral injections of vitamin B1 (50 mg x 2) at the tsusanli acupoint one time per day. This intervention was performed for a total of 5 consecutive days or until flatus.
gum chewingOther
Participants allocated to chewing gum were instructed to chew commercially available sugar-free gum (Extra \& Reg, Wm. Wrigley Jr. Co., Ltd., Shanghai, China) three times daily starting on the first postoperative morning. They were instructed to chew the piece of gum for at least 10 min. This intervention was performed for 5 consecutive days or until flatus.
| Study group | Role | What they receive |
|---|---|---|
| simo decoction and acupuncture with vitamin B1 | Experimental | Patients will receive simo decoction (10 mL/piece,three times per day) and bilateral tsusanli acupoint injections with vitamin B1 two times per day, starting in the first day after resection for 5 days or until flatus. Receives: Dietary Supplement: simo decoction |
| gum chewing | Active comparator | Patients will receive gum chewing (three times per day) in the first day after resection for 5 days or until flatus. Receives: Other: gum chewing |
| empty control | No intervention | Patients only receive best support care. |

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing simo decoction and gum chewing in people with Colorectal Cancer, run by Guangxi Medical University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
First flatus time (time frame: one day). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02813278, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jun 2016.
