Abstract

AbstractBackgroundIntestinal malrotation is a rare congenital condition with potentially devastating consequences due to potential volvulus and massive intestinal necrosis. Diagnosis is often delayed and long-term symptoms following surgical correction are poorly characterized. We developed theIntestinal Malrotation Patient Outcomes and WEllness Registry (IMPOWER), a national patient-generated registry (PGR), to capture data related to presenting symptoms, testing, diagnosis, treatment, and follow-up of individuals diagnosed with malrotation. IMPOWER captures patient-reported information from adult patients and parents/caregivers of children diagnosed with malrotation at the time of enrollment and at ongoing 6-month intervals. We present baseline characteristics of patients enrolled during the first two months of the registry.ResultsWithin the first two months, 354 patients with malrotation enrolled in IMPOWER, and 191 (53.9%) completed all baseline assessments. Nearly 90% of the 119 pediatric participants and 37.7% of the 72 adult participants experienced symptoms prior to diagnosis. Vomiting was the predominant symptom for pediatric participants compared to abdominal pain in adults. Yellow bilious emesis was more commonly reported than green, and volvulus at diagnosis occurred in 70% of pediatric and 27% of adult participants. One-third of pediatric participants had a bowel resection as part of their initial surgical procedure, resulting in 23.4% with diagnosed short bowel syndrome. More than 60% of pediatric and 80% of adult registrants reported gastrointestinal symptoms that persisted throughout the first year following their initial operation. Approximately 25% of registrants reported visiting four or more gastroenterologists for management of ongoing symptoms.ConclusionsFewer than half of pediatric patients presented with the “classic” presentation of green bilious colored emesis. Yellow bilious emesis was more commonly reported, and chronic gastrointestinal symptoms (i.e., abdominal pain, reflux, constipation, diarrhea) and feeding intolerance were common following surgical procedures for malrotation. This novel PGR highlights the need for a multicenter prospective registry to characterize the natural history and develop consistent standards of care related to the diagnosis, treatment, and long-term care for patients with malrotation.
