Improvement of Constipation Symptoms in an Older Adult Patient by Defecation Care Based on Using a Handheld Ultrasound Device in Home Care Settings: A Case Report

BACKGROUND: Although previous studies have demonstrated the ability of ultrasound to detect stool in the colon and rectum, the clinical utility of evaluating constipation via ultrasonic imaging by nurses has not been determined. In this case report, we observed fecal retention, assessed the presence of constipation, and performed defecation care in an older adult patient in a home care setting in a city near the metropolitan area in Japan. CASE: An 85-year-old male with advanced stage prostate cancer and multiple metastases was diagnosed with fecal impaction via digital rectal examination and evaluation of stool consistency. He was managed by regular digital evacuation of stool, but ultrasonic imaging indicated constipation with fecal retention in both the rectum and the colon despite this bowel evacuation program. When faced with this situation, we advocate a bowel management program that considers both intestinal elimination dysfunction and fecal transport dysfunction. Based on ultrasonic imaging, stool consistency was altered by promoting water intake, and we promoted self-defecation by asking the patient to attempt to move his bowels (regardless of cues to defecation) by sitting on the toilet every morning. As a result, the number of weekly enemas and digital dis-impaction episodes decreased while the number of spontaneous defecations increased. CONCLUSION: This case report demonstrated that ultrasonography improved bowel management in this patient with clinically severe chronic constipation.
