Pre-operative Nutrition for Elective Resection Surgery in Inflammatory Bowel Disease

March 4, 2026 updated by: NYU Langone Health
This study aims to determine if improved risk stratification tools and interventions to mitigate malnutrition reduce postoperative risk in patients undergoing elective or emergent resection surgery for inflammatory bowel disease (IBD), and if adding immune modulation nutrition improves surgical outcomes. The primary objective is to assess whether preoperative malnutrition screening and intervention minimize postoperative complications. The secondary objective is to evaluate whether immune modulation nutrition in the peri-operative period decreases length of stay and major complications.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Nutrition specialist
Participants will be assigned to this arm if the subject is determined malnourished. They will be sent to a nutrition specialist for a nutrition focused visit and will be provided standard of care intervention prior surgery.
Other: Nutrition specialist
Nutrition specialist to help improve nutritional status by diet, oral nutrition supplements or parenteral nutrition.
Dietary supplement: Ensure Surgery Immunonutrition shakes
All study subjects, including subjects without malnutrition, will be given the Ensure Surgery Immunonutrition Shakes for prior to surgery as per standard of care. All subjects will also receive additional shakes starting as an inpatient when diet is advanced.
Active Comparator: Standard of Care
Participants that show no signs of malnutrition will be assigned to this arm. The subject will be provided with education and schedule of Ensure® Surgery Immunonutrition shakes for prior to surgery as per standard of care.
Dietary supplement: Ensure Surgery Immunonutrition shakes
All study subjects, including subjects without malnutrition, will be given the Ensure Surgery Immunonutrition Shakes for prior to surgery as per standard of care. All subjects will also receive additional shakes starting as an inpatient when diet is advanced.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Length of hospital stay
Time Frame: Up to 30 days post-surgery
From the time the patient is admitted at hospital for surgery until the patient is discharged.
Up to 30 days post-surgery
Proportion of patients who experienced postoperative major complications
Time Frame: Visit 3 (30 days post-surgery)
Major complications include infection, bleeding (requiring blood transfusion or requiring intervention), cardiac event (myocardial infarction, arrhythmia, and cardiac arrest), stroke, acute kidney injury (increase in serum creatinine of ≥0.3 mg/dL from baseline or ≥1.5 times baseline), venous thromboembolism, reoperation, readmission, and need for ICU-level care. The outcome measure will be obtained from the electronic health record (EHR).
Visit 3 (30 days post-surgery)

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
