About this study

Official title: Clinical Study on the Effect of Traditional Chinese Medicine Formula Dachengqi Decoction on Early Gastrointestinal Function Recovery After Whipple Surgery

To investigate the clinical efficacy of the traditional Chinese medicine formula Dachengqi Decoction in promoting early gastrointestinal function recovery after Whipple surgery, and to evaluate its impact on postoperative nutritional status, hospitalization duration, and complication rates, thereby providing evidence for optimizing postoperative rehabilitation strategies in pancreaticoduodenectomy patients.

Read the detailed description

Study Design: This prospective, open-label, randomized controlled trial will enroll 45 patients undergoing pancreaticoduodenectomy (PD) or pylorus-preserving pancreaticoduodenectomy (PPPD) at the study center. Participants will be divided into three groups: the experimental group (15 patients receiving Dachengqi Decoction), the control group (15 patients receiving glucose-sodium chloride solution), and a retrospective blank control group (15 historical cases). Simple randomization will be applied for group allocation.

Intervention:

Experimental Group: Dachengqi Decoction (composed of Houpu 24g, Zhishi 12g, Dahuang 12g, and Mangxiao 9g) will be prepared by the hospital pharmacy. Administered at 50 mL twice daily via jejunal tube infusion (10 mL/h), starting 12 hours postoperatively for three consecutive days.

Control Group: Glucose-sodium chloride solution (250 mL: glucose 12.5g and sodium chloride 2.25g) will be administered using the same protocol.

Blank Control Group: No additional intervention; data will be retrospectively collected from eligible historical cases.

Key Procedures:

Baseline Assessments: Preoperative evaluations include medical history, physical examinations (e.g., bowel sounds), laboratory tests (blood counts, biochemistry, coagulation, inflammatory markers), imaging (CT/MRI), and validated scales (nutritional status, mental health, gastrointestinal function).

Intraoperative Management: Standardized anesthesia and placement of a dual-lumen feeding tube distal to the gastrojejunal anastomosis.

Postoperative Monitoring: Record time to first defecation, flatus, oral intake, ambulation, vomiting frequency, bowel sounds, pain scores, and complications (e.g., delayed gastric emptying [DGE]). Imaging (abdominal CT) and laboratory tests will be performed on postoperative days 1, 3, 5, 7, and 30.

Follow-Up: Assessments at 30 days post-surgery will include gastrointestinal function, nutritional status, and adverse events.

Endpoints:

Primary Endpoints: Gastrointestinal function (evaluated via standardized scales) and nutritional status (PG-SGA score) at 1 month postoperatively.

Secondary Endpoints: Total hospitalization duration, time to gastrointestinal recovery (flatus, defecation, oral intake), and incidence of complications (e.g., DGE graded by ISGPS criteria).

Statistical Analysis: Continuous variables will be analyzed using ANOVA or non-parametric tests, while categorical variables will be assessed with chi-square or Fisher's exact tests. Linear/logistic regression and Cox models will be applied for outcome analysis. A sample size of 15 per group was calculated (power=0.9, α=0.05).

Ethics and Compliance: The study protocol and informed consent forms will be approved by the institutional ethics committee. Participants or their legal representatives must provide written consent. Confidentiality of patient data will be maintained, and results will be disseminated through peer-reviewed publications.

Timeline: Patient enrollment is scheduled for completion by March 1, 2026, with final results expected by June 1, 2026.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Dachengqi decoctionDrug

    experimental Participants received Dachengqi decoction (50 ml BID) via pump infusion at 10 ml/h starting 12 hours postoperatively, continuing through postoperative days 1-3.

  • modified gastrointestinal dual-lumen feeding tubeProcedure or surgery

    experimental and control group participants underwent intraoperative placement of modified gastrointestinal dual-lumen feeding tubes with distal ends positioned 15-20 cm distal to the gastrojejunostomy anastomosis (all devices were uniformly procured by China-Japan Friendship Hospital).

  • Normal Saline (0.9% NaCl)Drug

    control group participants were administered glucose and sodium chloride injection (50 ml BID) via pump infusion at 10 ml/h starting 12 hours postoperatively, continuing through postoperative days 1-3.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. One month postoperative evaluation of gastrointestinal function

    assessed through three independent systems: Functional bowel recovery: Evaluated through I-FEED scoring system (0-10; lower score reflects better postoperative recovery)

    Measured: 1 month after surgery

Secondary outcomes (1)
  1. postoperative assessment of gastrointestinal functional recovery

    Time to first flatus (hours) Time to first bowel movement (hours) Time to oral intake initiation (hours) Time to first ambulation (hours)

    Measured: From surgery date through postoperative day 30.

Questions about this trial

What is this clinical trial studying?

A study testing Dachengqi decoction, modified gastrointestinal dual-lumen feeding tube and Normal Saline (0.9% NaCl) in people with Whipple Operation, run by China-Japan Friendship Hospital 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 5 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: under way, not looking for participants, as of the sponsor's last update on 29 Apr 2025. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

One month postoperative evaluation of gastrointestinal function (time frame: 1 month after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 29 Apr 2025.
