Case ReportEmergency incarcerated obturator hernia repair with biologic mesh in a male patient after ipsilateral hip disarticulation: A case report

•Obturator hernias are rare and may have increased morbidity in the presence of a hip disarticulation due to altered anatomy.•Obturator hernias after an ipsilateral hip disarticulation can be treated through the reduction of bowel and hernia repair with mesh.•A high index of suspicion is necessary for early diagnosis and prompt surgical intervention, along with appropriate education for healthcare providers and patients.

IntroductionAn obturator hernia is an uncommon form of abdominal hernia that is difficult to diagnose due to its non-distinct presentation. This case investigates an emergency treatment of an obturator hernia presenting in a patient with an ipsilateral hip disarticulation in a 266-bed community hospital.Presentation of caseA 53-year old man with a history of a left hip disarticulation 3-weeks prior presented to the emergency department with fever, nausea, vomiting, and diarrhea for the past 5-days. An elevated WBC and presence of gas within the hip stump on CT led to an emergency operation to rule out necrotizing fasciitis within the stump. Opening of the stump incision revealed two herniated loops of small bowel corresponding to the left obturator foramen, revealing the diagnosis of an incarcerated obturator hernia. The bowel was reduced and secured within the hip stump and the defect was covered with Strattice biologic mesh.DiscussionObturator hernias are rare and can involve vague symptoms, but it is essential to make an accurate diagnosis and repair the defect on an emergency basis. Obturator hernias may appear in the setting of a hip disarticulation, being caused by iatrogenic anatomic alteration, and can be treated in a community acute care hospital.ConclusionBeing aware of the possibility of obturator foramen herniation and bowel incarceration as part of the differential diagnosis for patients with abdominal pain after a prior hip disarticulation can facilitate prompt diagnosis and reduce morbidity and mortality.
