Trimebutine Maleate for Enhancing Gastric Visualization in Acute Upper Gastrointestinal Bleeding

August 1, 2026 updated by: Mohammad Saleh, Assiut University

Role of Trimebutine Maleate in Enhancing Endoscopic Gastric Visualization in Patients With Acute Upper Gastrointestinal Bleeding: A Double-Blind Randomized Controlled Trial

Acute upper gastrointestinal bleeding is a medical emergency that requires an urgent upper endoscopy to locate and treat the source of the bleeding. Often, retained blood and clots in the stomach make it difficult for the endoscopist to clearly see the stomach's anatomical structures.

This study aims to evaluate if administering a medication called Trimebutine Maleate before the endoscopy can help empty the stomach of residual blood and improve the doctor's view. Trimebutine Maleate is a widely prescribed medication that regulates gastrointestinal movement and has a favorable safety profile compared to other medications used for this purpose.

Researchers will include 100 adult patients experiencing acute upper gastrointestinal bleeding who are scheduled for an urgent endoscopy within 24 hours of presentation. Participants will be randomly assigned to receive either 50 mg of intravenous Trimebutine Maleate or a matching placebo (saline solution) 60 to 90 minutes before their procedure. All participants will continue to receive standard medical treatment for their bleeding according to normal hospital protocols.

The primary goal of the study is to compare the clarity of the stomach view between the two groups using a standardized Gastric Visualization Score. The research team will also measure how often the exact bleeding source is successfully identified, the total duration of the procedure, and whether patients require a repeat endoscopy or a stomach washout (gastric lavage).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Trimebutine Maleate Group
Participants in this group will receive an intravenous administration of 50 mg Trimebutine Maleate approximately 60 to 90 minutes prior to their scheduled urgent upper gastrointestinal endoscopy. All patients will also receive standard medical treatment for acute upper gastrointestinal bleeding according to institutional protocols.
Drug: Trimebutine Maleate
50 mg of Trimebutine Maleate administered intravenously approximately 60 to 90 minutes prior to the scheduled urgent upper gastrointestinal endoscopy.
Placebo Comparator: Placebo Group
Participants in this group will receive a matching placebo, consisting of an ampoule of saline, administered approximately 60 to 90 minutes prior to their scheduled urgent upper gastrointestinal endoscopy. All patients will also receive standard medical treatment for acute upper gastrointestinal bleeding according to institutional protocols.
Other: Placebo
A matching placebo consisting of an ampoule of saline administered intravenously approximately 60 to 90 minutes prior to the scheduled urgent upper gastrointestinal endoscopy.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Total Gastric Visualization Score
Time Frame: 60 to 90 minutes post-intervention
Gastric visualization will be assessed by the endoscopist across five anatomical areas: the fundus, upper body, lower body, antrum, and duodenum. Each area is evaluated using a 4-point scale: 0 (large amount of blood/clots obscuring vision), 1 (moderate blood requiring suction), 2 (small amount of blood with adequate visualization), and 3 (excellent visualization). The scores from all five areas are summed to create a Total Gastric Visualization Score ranging from 0 to 15, with higher scores indicating better visualization.
60 to 90 minutes post-intervention

Secondary Outcome Measures

Measure Description
Time Frame
Identification Rate of Bleeding Source
Time Frame: 60 to 90 minutes post-intervention
Percentage of participants in whom the specific anatomical source of upper gastrointestinal bleeding is successfully identified during the endoscopy procedure.
60 to 90 minutes post-intervention
