Intestinal malrotation, a congenital condition also known as gut malrotation, occurs when the intestines do not properly rotate and fixate during fetal development. While often diagnosed in infancy, it can, though rarely, present in adulthood. This article delves into the dietary considerations and management strategies for adults with intestinal malrotation, leveraging recent research and clinical insights.
Understanding Intestinal Malrotation
During pregnancy, a baby’s bowel normally rotates 270 degrees counterclockwise and then becomes fixed in position. Malrotation occurs in about one out of every 500 births in the United States. In cases of gut malrotation, this embryonic process is defective and sometimes associated with mal-development of the gut, abdominal wall and the nerve supply of the intestine. This can lead to a variety of gastrointestinal symptoms and potentially life-threatening complications, such as volvulus (twisting of the intestines).
Symptoms and Diagnosis in Adults
Malrotation in adults may present in an acute way due to midgut volvulus or may have a chronic indolent course with recurrent vomiting and abdominal pain. Symptoms in adults can be vague and intermittent, often leading to delayed diagnosis. These may include:
- Recurrent abdominal pain
- Nausea and bloating
- Food intolerance
- Altered bowel habits
- Bilious vomiting
Contrast-enhanced computerized tomography (CT) is the investigation of choice and reveals typical findings, like whirlpool sign, corkscrew sign, or reversed relation of superior mesenteric artery and vein. If this condition is not timely recognized, it may result in disastrous consequences, such as gangrene of the small gut.
Dietary Considerations for Adults with Intestinal Malrotation
While surgery is often necessary to correct the anatomical issues, dietary management plays a crucial role in alleviating symptoms and maintaining nutritional status, especially for those who have undergone surgical interventions or experience chronic symptoms.

Post-Surgical Diet: Following surgical correction, a gradual introduction of food is essential.
- Clear Liquids: Initially, a diet of clear liquids helps assess tolerance and bowel function.
- Low-Residue Diet: Progressing to a low-residue diet minimizes bowel stimulation and reduces the risk of obstruction.
- Small, Frequent Meals: Eating smaller meals more frequently can ease digestion and prevent overloading the intestines.
Managing Food Intolerances: Many individuals with intestinal malrotation experience food intolerances.
- Elimination Diet: An elimination diet, under the guidance of a healthcare professional, can help identify trigger foods.
- Common Irritants: Common culprits include gluten, lactose, and high-fat foods.
Nutritional Support: Adequate nutrition is vital, particularly if malabsorption is present.
- Vitamins and Minerals: Supplementation may be necessary to address deficiencies.
- Parenteral Nutrition: In severe cases, intravenous nutrition may be required to ensure adequate nutrient intake.
Diet for Specific Symptoms: Addressing specific symptoms through dietary adjustments can improve quality of life.
- High-Fiber Diet: For altered bowel habits, a balanced intake of soluble and insoluble fiber can help regulate bowel movements.
- Low-FODMAP Diet: For bloating and abdominal pain, a low-FODMAP diet may reduce gas production and discomfort.
Surgical Interventions
The operation that has been used traditionally to address intestinal malrotation is called the Ladd’s procedure, which untwists the intestines and alleviates the bowel obstruction by dividing adhesive bands between the duodenum (upper part of the small intestine) and colon. However, despite the relief of the obstruction with some temporary improvement in patient’s symptoms, the Ladd’s procedure does not prevent the intestine from recurrent future twisting, which can cut off the blood supply and be life-threatening at any age.

Drawing on 30 years of experience in digestive surgery and transplantation, Kareem Abu-Elmagd, M.D., Ph.D. - director of Cleveland Clinic’s Center for Gut Rehabilitation and Transplantation and lead author of the study - developed a new gut malrotation correction surgery to alleviate the gastrointestinal symptoms as well as prevent the need for gut transplantation. “During the procedure, the digestive organs are rearranged and fixed in their proper anatomic locations, which prevents the intestines from twisting and resolves the digestive symptoms with improved quality of life,” said Dr. Abu-Elmagd.

- Kareem’s Procedure: A newer procedure developed at the Cleveland Clinic rearranges and fixes the digestive organs to prevent future twisting.
The Role of the "Kareem's Procedure"
Drawing on 30 years of experience in digestive surgery and transplantation, Kareem Abu-Elmagd, M.D., Ph.D. - director of Cleveland Clinic’s Center for Gut Rehabilitation and Transplantation and lead author of the study - developed a new gut malrotation correction surgery to alleviate the gastrointestinal symptoms as well as prevent the need for gut transplantation. “During the procedure, the digestive organs are rearranged and fixed in their proper anatomic locations, which prevents the intestines from twisting and resolves the digestive symptoms with improved quality of life,” said Dr. Abu-Elmagd.
In this study, the Kareem’s procedure was performed on 80 patients with intact gut and disabling symptoms - 92% were adults and 8% were children. Soon after surgery, the digestive symptoms improved significantly. With up to 10 years of follow-up, most of those patients are able to eat normally and have a better quality of life. None of the patients developed volvulus following the Kareem’s procedure.
Long-Term Management and Considerations
Long-term management of intestinal malrotation in adults requires a multidisciplinary approach, including dietary modifications, medical management, and regular monitoring.
- Regular Follow-Up: Routine check-ups with a gastroenterologist can help monitor symptoms and detect potential complications early.
- Lifestyle Adjustments: Stress management and regular exercise can improve overall digestive health.
- Awareness and Education: Understanding the condition and its potential complications is crucial for proactive management.
Importance of Early Diagnosis
This study also shows that more awareness about intestinal malrotation is needed to proactively treat the disorder and prevent its potentially life-threatening complications. “Overlooked symptoms or misdiagnosis can result in a delay to receive life-changing care,” said Dr. Abu-Elmagd. “Therefore, it is important to diagnose the congenital disorder early in life - possibly with increased efforts to establish perinatal screening programs - so patients can receive an effective surgical treatment in a timely manner to prevent volvulus and save their gut.”
