Overview
The goal of this clinical trial is to evaluate if intensified omeprazole therapy can reduce high-output stoma (HOS) in adults undergoing ileostomy formation surgery. The main objectives of the study are:
- To assess if intensified omeprazole treatment significantly reduces mean daily ileostomy output (ml/24h) during the first three postoperative days compared to standard omeprazole treatment.
- To evaluate the proportion of patients meeting the criteria for high-output stoma (HOS ≥1400 ml/day) on consecutive postoperative days.
- To measure the time required for stabilization of ileostomy output (<1400 ml/day maintained for three consecutive days).
- To determine the incidence of dehydration-related complications, specifically electrolyte disturbances (hyponatremia, hypokalemia).
- To compare the length of initial hospital stay, frequency of rehospitalizations within 30 days post-discharge, and total length of hospital stay (including rehospitalizations).
Researchers will compare 10 days intensified omeprazole treatment (loading dose of 80 mg IV followed by 40 mg IV twice daily) with standard treatment (40 mg IV once daily) to determine the effectiveness of intensified dosing in reducing ileostomy output and improving postoperative outcomes.
Participants will:
- Receive either standard or intensified intravenous omeprazole during their hospitalization and after discharge for 10 days combined.
- Undergo daily measurements of ileostomy output.
- Have routine laboratory assessments of electrolyte levels.
- Participate in follow-up assessments up to 30 days post-discharge, conducted either through outpatient visits or telephone consultations.
Description
This clinical trial investigates whether intensified omeprazole therapy can effectively reduce a condition known as high-output stoma (HOS) in adult patients undergoing ileostomy surgery. Ileostomy surgery involves creating an opening in the abdomen (stoma) to divert waste away from a diseased or surgically removed section of the intestine. After this procedure, some patients develop an excessive fluid output from the stoma, known as high-output stoma, defined as the production of more than 1400 ml of fluid per day. This excessive fluid loss can cause serious health issues, including severe dehydration, electrolyte imbalances (such as low sodium or potassium levels), nutritional deficiencies, increased risk of kidney problems, cardiovascular complications, and prolonged hospital stays.
Currently, the standard treatment for managing high-output stoma includes dietary changes, restricting fluid intake, administering anti-diarrheal medications like loperamide, and providing intravenous fluids and electrolytes. However, many patients continue to experience high stoma output despite these standard treatments.
Previous studies have suggested that proton pump inhibitors (PPIs) such as omeprazole, medications commonly used to reduce stomach acid, may help decrease the total amount of intestinal fluid produced. Omeprazole increases the pH level (reduces acidity) of the stomach contents, which might reduce irritation in the intestine and slow down fluid loss from the stoma. Although initial results are promising, current data are limited.
In this randomized clinical trial, researchers aim to determine if providing an intensified dosing regimen of omeprazole can significantly reduce ileostomy fluid output and improve clinical outcomes compared to the standard dosing. The study will include adult patients scheduled for elective or emergency ileostomy surgery.
Participants will be randomly assigned to one of two groups:
- Standard treatment group: Participants will receive the standard hospital treatment, which includes a daily intravenous dose of 40 mg omeprazole each morning.
- Intensified treatment group: Participants will receive an intensified regimen of omeprazole, starting with an initial intravenous loading dose of 80 mg, followed by 40 mg given twice daily (morning and evening) for 10 days.
The study's primary objective is to evaluate whether the intensified omeprazole treatment reduces the average daily ileostomy fluid output in the first three days after surgery. Additional objectives include assessing how quickly stoma output stabilizes (defined as output less than 1400 ml/day for three consecutive days), comparing the incidence of dehydration-related complications such as electrolyte imbalances, evaluating differences in hospital stay duration, and monitoring the rates of rehospitalization within 30 days after discharge.
Participants in both groups will undergo daily monitoring of their ileostomy output and regular blood tests to check electrolyte levels during their hospital stay. After discharge, participants will continue to be followed for 30 days through outpatient visits or telephone consultations to monitor any further complications or health issues.
The findings of this study could provide crucial evidence regarding the benefits of intensified omeprazole therapy. If proven effective, this approach may significantly improve patient outcomes, reduce the frequency of complications associated with high-output stomas, shorten hospital stays, and lower healthcare costs related to postoperative care.
