Role of contrast-enhanced serial/spot abdominal X-rays in perioperative follow-up of patients undergoing abdominal surgery: An observational clinical study.

Background: Many imaging methods such as ultrasonography, computed tomography (CT), magnetic resonance imaging, and endoscopy are used to identify the problems or complications that occur in the perioperative period and to determine the appropriate therapeutic approach. Specialists at surgical clinics and intensive care units sometimes need diagnostic procedures that can give quick results or reveal unexpected results. In particular, rapid on-site evaluation of patients followed under intensive care conditions has several advantages.

Aim: To determine the problems developing in patients in the perioperative period by contrast-enhanced abdominal X-ray (CE-AXR), revealing their current status or defining the effectiveness of CE-AXR.

Methods: The files of the patients who underwent hepatopancreatobiliary or upper gastrointestinal surgery, whose CE-AXR film was taken, were reviewed retrospectively. Abdominal X-ray radiographs taken after ingestion of a water-soluble contrast agent (iohexol, 300 mg, 50 cc vial) and its application in a drain, nasogastric tube, or stent were evaluated. The contribution of the data obtained in patients who underwent CE-AXR to the diagnosis, follow-up, and treatment processes and the effectiveness of the application were investigated.

Results: CE-AXR was applied to 131 patients in our clinic, most of whom underwent hepatopancreatobiliary or upper gastrointestinal surgery. It was determined that the data obtained from CE-AXR films taken in 98 (74.8%) of the patients contributed to the diagnosis, treatment, and follow-up expectations and positively affected the clinical processes.

Conclusion: CE-AXR is a simple procedure that can be applied anywhere, especially in intensive care patients and at bedside, with a portable X-ray device. The simplicity of the procedure, less radiation exposure for the patients, less time wastage, reduction in the CT and endoscopy procedure burden and costs, quick results, rapid assessment of the situation, and enabling the monitoring of processes with repetitive procedures are important advantages. X-rays taken will be useful in terms of being a reference value during the follow-up period of the patient and determining the situation in medicolegal processes.
