A 53-year-old female patient with an 11-year history of Crohn’s disease arrived at the emergency department reporting paroxysmal abdominal pain that had deteriorated over the previous 24 hours. Her presentation included bowel disorders such as diarrhea, as detailed in the medical literature published in the journal Cureus.
Emergency Department Arrival and Presentation
Despite her severe discomfort, her vital signs remained unremarkable. She presented with an arterial blood pressure of 126/85 mmHg, an oxygen saturation of 96%, and a heart rate ranging between 90 and 95 beats per minute. Her decade-long conservative management with budesonide had previously kept the chronic condition in check. Yet, clinical examination now revealed mild flatulence and reduced bowel sounds, while initial blood laboratory values fell within normal ranges.
Multidetector CT Scans Reveal Complex Pathologies
Diagnostic imaging quickly shifted the clinical picture. An upright abdominal X-ray first revealed air-fluid levels that raised suspicion of an incomplete ileus.
To pinpoint the issue, clinicians administered multidetector computed tomography (MDCT) scans of the abdomen using 100 mL of intravenous iodinated contrast. The scans identified focal areas of wall thickening in the transverse colon and the lower aspect of the stomach. These findings matched skip lesions typically associated with Crohn’s disease, supported by adjacent fat stranding and reactive lymph nodes.
Uncovering a Rare Gastrocolic Fistula
The imaging exposed a rare gastrocolic cutaneous fistula—an uncommon complication of Crohn’s disease requiring precise diagnostic imaging and surgical intervention to manage upper and lower digestive tract symptoms.
During an exploratory laparotomy, surgeons located an inflammatory mass in the middle of the transverse colon. They confirmed a direct communication with the stomach, definitively establishing the gastrocolic fistula.
Surgical Intervention and Smooth Recovery
Faced with the diagnosis, the surgical team performed an excision of the affected segment of the transverse colon alongside a cuneiform resection of the stomach in the region of the fistula. The procedure successfully addressed the pathology.
According to the surgical team, the patient experienced a smooth and uncomplicated postoperative recovery. She was discharged from the hospital on the tenth day following the operation.
Modern Imaging Shifts the Diagnostic Standard
Medical literature highlights a notable shift in how these rare conditions are caught. Historically, gastrointestinal fistulas presented with pronounced clinical symptoms such as fecal vomiting, weight loss, or the passage of indigestible food in stool.
Today, the widespread use of multidetector CT scans allows for much earlier detection. Surgical treatment—utilizing either open or laparoscopic approaches—remains the gold standard for managing these fistulas in patients with Crohn’s disease, effectively controlling the underlying inflammatory process and preventing further complications.
