Navigating Constipation in the Elderly: A Modern Approach to Relief
"Discover how colonic ultrasonography offers a personalized solution for managing constipation in older adults, improving their comfort and care."
Chronic constipation significantly affects many older adults, with up to 50% of those in long-term care (LTC) facilities experiencing its discomfort. However, defining constipation in the elderly can be challenging due to varying perceptions and communication difficulties, especially among those with cerebrovascular diseases or dementia.
Untreated constipation can lead to severe complications such as impaction or perforation. Therefore, effective management and prevention are crucial. While conventional methods include diet and lifestyle changes, inappropriate medication is common. Precisely assessing fecal retention is essential to avoid over-management and potential adverse effects.
Traditional diagnostic tests like abdominal radiography and colonoscopy have limitations, including radiation exposure and invasiveness. Colorectal ultrasonography (US) offers a safe, cost-effective alternative for assessing fecal retention. A recent study explores the use of colonic US in Japanese LTC facilities to provide insights into constipation management in the elderly, considering their unique physiological factors.
Ultrasound-Guided Assessment
The Chronic Constipation Ultrasound Study Group, affiliated with the Diagnosis and Treatment of Chronic Constipation Study Group, proposed a straightforward functional evaluation method for chronic constipation. The group includes professionals from various disciplines involved in treating chronic constipation. The approach is presented as a way to support more tailored assessment and management, although the available source material does not establish that it replaces other diagnostic methods.
Early Ultrasound Practice
An original article documented sonographic examinations lasting approximately 10 minutes. The examinations were performed by a certified sonographer with 30 years of experience. The equipment was a Noblus ultrasound system from Hitachi Aloka Medical Ltd. in Tokyo, Japan, using a curved-array 5 MHz probe.
Colonic Ultrasonography: A New Perspective on Fecal Retention
A study conducted in a Japanese LTC medical facility (Sengi Hospital) from March to April 2016, explored using colonic ultrasonography to assess fecal retention in elderly patients experiencing chronic constipation. The study aimed to determine the correlation between nutrition management methods and fecal retention as visualized by US. Participants included individuals aged 65 years and older who met the Rome III criteria for functional constipation, while those with abdominal surgery history, irritable bowel syndrome, organic disease, or significant colon gas were excluded.
- US Imaging Process: The colorectum of each patient was scanned using a systematic method, capturing images at the ascending, transverse, descending, and sigmoid colon, as well as the rectum. This process, lasting approximately 10 minutes, was conducted by a certified sonographer using a curved-array probe.
- Data Analysis: US images taken before constipation management were classified based on fecal retention. High echogenicity, brightness of the colon wall, and posterior acoustic shadows indicated fecal retention. Two certified sonographers visually classified the images to ensure reliability.
- Statistical Analysis: The correlation between fecal retention, nutrition management methods, stool characteristics, and bowel movement frequency were analyzed using statistical tests to determine significant relationships.
Recent Evidence on Ultrasound
A literature review reports that faecal retention can be evaluated objectively and noninvasively with ultrasound imaging equipment. A study using the transgluteal cleft approach reported 100.0% sensitivity and 100.0% specificity for detecting fecal retention in the rectum. A meta-analysis found that rectal diameter was associated with clinical constipation in 29 pediatric studies involving 3,331 patients. Separately, a defecation-care algorithm study reported no adverse events and significant reductions in hard stools and artificial defecation.
Limits of Ultrasound Alone
An investigation in a Japanese long-term medical facility reported that constipation could not be assessed adequately from ultrasound images alone. The source emphasizes that no single test can fully assess the pathophysiology of constipation because fecal retention is a physiological phenomenon occurring in the colon. A separate review examined ultrasonography's accuracy for detecting constipation in elderly people who cannot clearly communicate their symptoms, drawing on longitudinal observational, cross-sectional, and case-control studies.
Noninvasive Comparative Assessment
Ultrasonography is described as noninvasive, low-cost, simple, and repeatable for chronic constipation assessment. One study evaluated whether ultrasonography could predict favorable outcomes from different medical therapies in 223 patients with chronic constipation, including 75 men and 148 women. In a separate longitudinal study of older people with physical and cognitive impairment living in long-term care facilities, 64 patients, or 74.4%, had ultrasound findings with acoustic shadowing in the rectum.
Embracing Personalized Care Through Technology
Colonic ultrasonography offers a promising avenue for personalized medical care for elderly patients experiencing constipation. By accurately assessing fecal retention and tailoring nutrition management accordingly, healthcare providers can avoid uniform, potentially excessive treatments. Further research and application of this technology may significantly improve the quality of life for older adults in long-term care facilities, ensuring their comfort and well-being through targeted and effective interventions.
Toward Portable Care
The 2025 study reports that portable ultrasound is likely to become increasingly important as a next-generation examination device in nursing care. It characterizes transabdominal ultrasonography, including portable ultrasound, as noninvasive, simple, and repeatable. The authors propose that it may become a fundamental modality in chronic constipation management among elderly people.
