Stercoral Colitis in the Emergency Department: A Retrospective Review of Presentation, Management, and Outcomes

High risk and low incidence diseases: Stercoral colitis

INTRODUCTION

Stercoral colitis is a rare but serious diagnosis which is associated with a high rate of morbidity.

OBJECTIVE

This review highlights the pearls and pitfalls of stercoral colitis, including presentation, diagnosis, and emergency department (ED) management based on the available evidence.

DISCUSSION

Stercoral colitis is an uncommon inflammatory condition of the distal large bowel and rectum resulting from accumulation of impacted stool and is associated with several complications including bowel ulceration, ischemia, perforation, peritonitis, and sepsis. Though most commonly present with abdominal pain and constipation, many patients present without typical symptoms requiring emergency clinicians to maintain high clinical suspicion, especially in patients at high risk for developing severe constipation. The diagnosis can be secured with cross-sectional radiography, including computed tomography of the abdomen and pelvis. ED management includes fluid resuscitation, initiation of a multimodal bowel regimen, and if indicated, initiation of parenteral antibiotics and consultation with a surgical specialist. Admission to the hospital should be considered for all patients with stercoral colitis.

CONCLUSIONS

An understanding of stercoral colitis can assist emergency clinicians in diagnosing and appropriately managing this high risk disease.

Stercoral Colitis: Review of Imaging Features and Complications

Stercoral colitis is an inflammatory reaction secondary to fecal impaction and almost always occurs in the setting of chronic constipation. Luminal distention caused by dense and dehydrated stool compresses the vascular supply of the distal colon, resulting in bowel ischemia and ulceration. Stercoral colitis primarily affects elderly patients, but it can be seen in any patient with decreased bowel motility, with risk factors including neurodegenerative disorders, chronic medical diseases, malignancy, immobility, and the use of narcotic or anticholinergic medications. Patients most often present with abdominal pain and tenderness. However, the presentation is often nonspecific and can include nongastrointestinal symptoms. Due to the common presence of comorbidities, a thorough history and physical examination findings may be difficult to obtain. Imaging, especially CT, plays a vital role in the diagnosis of stercoral colitis, demonstrating hallmark features such as fecal impaction and a large colorectal stool burden. Mural thickening (>3 mm) and other CT signs of inflammation aid in diagnosis, although findings including perirectal fat stranding can be nonspecific. Signs of perforation, including mural discontinuity, extraluminal air, and extraluminal stool collections, can also be identified. Other potential complications include obstruction, bleeding, fistulas, and urinary tract involvement secondary to mass effect. The overlap of findings between stercoral colitis and other colonic diseases, particularly diverticulitis and malignancy, can sometimes make diagnosis challenging. Identification of fecal impaction and associated inflammatory changes helps in distinguishing stercoral colitis from other pathologic conditions. Prompt diagnosis of stercoral colitis and its complications allows appropriate management, which can range from preventive measures to emergent surgical treatment. ©RSNA, 2025 Supplemental material is available for this article.

Perforated Stercoral Ulceration of Transverse Colon in the Setting of Multiple Comorbidities: A Case Report

Stercoral colitis is an inflammatory condition resulting from the long-term collection of fecal matter that may lead to colonic ulceration and perforation, consequently representing a surgical emergency. Herein, we present the case of a 65-year-old female who developed stercoral ulceration of the transverse colon, an uncommon location of occurrence. The patient had multiple comorbid conditions and risk factors for stercoral colitis that included a history of constipation, major depressive disorder, hypothyroidism, and a partial colonic resection due to an upper rectal perforation secondary to diverticulitis. With features of peritonitis on physical examination, historical, and computed tomography findings, the patient underwent urgent open abdominal exploration with colonic resection of the impacted bowel and end transverse colostomy. The patient had a complicated postoperative course owing to a respiratory infection and intraabdominal abscess formation but adequately recovered to be discharged home. Thus, urgent surgical intervention is necessary for survival in patients with stercoral ulceration, but modification of risk factors may be crucial in preventing stercoral colitis and its potentially fatal complications.

18 F-FDG PET/CT Findings of a Patient With Stercoral Colitis

ABSTRACT

Stercoral colitis is a colonic inflammation caused by fecal impaction. It is now more commonly discussed in the literature due to its clinical significance, which has gained recognition in recent years. Delayed diagnosis may result in complications such as sepsis and perforation, which have a high mortality rate. Reporting incidentally detected stercoral colitis on FDG PET/CT can help prevent mortality and morbidity by enabling early diagnosis and treatment. In this case, we report on a patient with gastric cancer who was identified with stercoral colitis using FDG PET/CT data.

Glucagon-Like Peptide-1 Receptor Agonist Cases Reported to United States Poison Centers, 2017-2022

INTRODUCTION

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are a class of medications for management of diabetes and obesity. The objective of this study is to characterize the epidemiology of GLP-1RA cases reported to US poison centers.

METHODS

We analyzed cases involving a GLP-1RA reported to the National Poison Data System during 2017-2022.

RESULTS

There were 5,713 single-substance exposure cases reported to US poison centers involving a GLP-1RA. Most cases were among females (71.3%) and attributable to therapeutic errors (79.9%). More than one-fifth (22.4%) of cases were evaluated in a healthcare facility, including 0.9% admitted to a critical care unit and 4.1% admitted to a non-critical care unit. Serious medical outcomes were described in 6.2% of cases, including one fatality. The rate of cases per one million US population increased from 1.16 in 2017 to 3.49 in 2021, followed by a rapid increase of 80.9% to 6.32 in 2022. Trends for rates of serious medical outcomes and admissions to a healthcare facility showed similar patterns with 129.9% and 95.8% increases, respectively, from 2021 to 2022.

CONCLUSIONS

Most GLP-1RA cases reported to US poison centers were associated with no or minimal effects and did not require referral for medical treatment; however, a notable minority of individuals experienced a serious medical outcome or healthcare facility admission. The rate of reported cases increased during the study period, including an 80.9% increase from 2021 to 2022. Opportunities exist to improve provider and patient awareness of the adverse effects of these medications.

Stercoral Colitis: An Unexpected Presentation in a Young Adolescent

Stercoral colitis is an uncommon inflammatory condition primarily affecting individuals with chronic constipation, immobilization, and advanced age, occasionally manifesting in pediatric patients. It arises from the accumulation of impacted fecal matter, leading to colonic distension and subsequent fecaloma formation, culminating in pressure necrosis and perforation. Mortality rates can exceed 60% in vulnerable populations due to complications such as colonic perforation and ischemia. Presented is the case of a 14-year-old female with stercoral colitis, initially presenting with diarrhea, abdominal pain, and metabolic acidosis. Despite improvement followed by a sudden deterioration, diagnostic challenges persisted, highlighting the complexity of diagnosing this condition, especially in pediatric cases. Key diagnostic criteria include vague abdominal symptoms, leukocytosis, and elevated inflammatory markers, alongside potential metabolic derangements. Imaging modalities, such as abdominal CT scans, aid in diagnosis, delineating features like colonic distension and wall thickening. Treatment strategies encompass aggressive bowel disimpaction, with endoscopic or surgical interventions reserved for refractory cases or perforations. Recognition of stercoral colitis is crucial for timely intervention, given its significant morbidity and mortality. Although typically associated with elderly or bedbound patients, the condition can also affect younger individuals, emphasizing the importance of considering it in the differential diagnosis, particularly in cases of chronic constipation. Integration of diagnostic imaging techniques facilitates accurate diagnosis, guiding appropriate therapeutic interventions and potentially mitigating adverse outcomes.

Stercoral colitis in the emergency department: a review of the literature

BACKGROUND

Stercoral colitis (SC) is a rare but potentially life-threatening inflammatory colitis caused by the accumulation of impacted fecal material. Despite reported associations with bowel perforation and high mortality rates, stercoral colitis remains a poorly defined and underrecognized diagnosis in the emergency department (ED).

OBJECTIVE OF THE REVIEW

This review aims to summarize and synthesize existing literature on SC to guide its recognition and management in the ED.

DISCUSSION

SC primarily occurs in elderly or bedbound patients with chronic constipation; however, it does occur in younger patients with comorbidities at increased risk for fecal impaction. Patients may present acutely with abdominal pain and distension, but clinical presentation is often nonspecific and varied, and there are no established diagnostic criteria for SC to date. CT is therefore crucial for diagnosis, revealing key findings such as fecaloma, colonic dilatation, and fat stranding. Treatment depends on severity of illness, ranging from manual disimpaction and other conservative measures for most cases, to surgical intervention for complicated cases, such as stercoral perforation.

CONCLUSIONS

SC can be a challenging diagnosis in the ED, often requiring multidisciplinary collaboration. Timely recognition and appropriate treatment are essential to reduce morbidity and mortality associated with this condition. Further research is needed to establish diagnostic criteria and clear management algorithms.

Seeds of Discomfort: An Unusual Case of Pediatric Abdominal Pain

This case describes a seven-year-old healthy boy who presented with seven days of abdominal pain, small-volume liquid stools, tenesmus, fevers, and dehydration after consuming an unknown amount of shelled watermelon seeds. He was ultimately found to have a large rectal seed bezoar that caused irritation, resulting in stercoral colitis with rectal inflammation. He was additionally found to have sigmoid volvulus during one of his disimpactions, which was also likely secondary to his rectal seed bezoar. This case uniquely highlights the importance of maintaining an index of suspicion for rectal seed bezoars, discusses previously unreported pediatric complications of rectal seed bezoars, including stercoral colitis and sigmoid volvulus, and addresses the management of this rare presentation.

Stercoral Colitis Secondary to Opiate-Induced Constipation

The authors present the case of a 62-year-old woman who had stercoral colitis secondary to opiate use for rheumatoid arthritis leading to chronic constipation. Computed tomography imaging demonstrated stool along a significant length of the colon. Stercoral colitis is a seldom suspected cause of severe abdominal pain. Although constipation may seem benign, when it gets to the level of a stercoral colitis, mortality due to colonic perforation is a very real concern. The authors review the presentation, risk factors, and management of stercoral colitis.

Fecal Impaction and Nonperforated Stercoral Colitis: Red Flags for Poor Outcomes

Fecal impaction and stercoral colitis are common, yet little research has been performed on the associated mortality risk. We performed a retrospective cohort study of 970 hospital encounters representing 885 unique patients in which fecal impaction or stercoral colitis was identified in CT reports. Among the 535 patients with fecal impaction, 13.3% died or were discharged to hospice, compared to 13.1% among the 428 patients with nonperforated stercoral colitis (p = 0.93). Of the seven patients with perforation, five died or were discharged to hospice. The risk of death or discharge to hospice for patients with fecal impaction or nonperforated stercoral colitis aged 18-49 was 2.9% and rose approximately 4% each decade thereafter to 21.9% for patients 90 and older (p< 0.001). Patients with a body mass index of 25-30 had an 8.1% risk of death or discharge to hospice, compared to 23.4% for those with a BMI < 18.5 (p< 0.001). Patients with at least one ICD-10 code for dementia, paralysis/neuromuscular disease, or malnutrition/failure to thrive had a risk of death or discharge to hospice of 21.6%, compared to 1.9% among patients with none of these risk factors (p< 0.001). ICD-10 codes for sepsis were associated with 90.0% of the deaths and 44.3% of the discharges to hospice. Patients diagnosed in less than three hours had a risk of death or discharge to hospice of 8.0%, compared to a risk of 20.1% for those diagnosed in ≥ 12 hours (p< 0.001).
