Constipation presenting as respiratory distress

Prevalence, Recognition, and Risk Factors of Constipation among Medically Hospitalized Patients: A Cohort Prospective Study

Background and Objective: Constipation is a prevalent gastrointestinal condition that has a substantial impact on individuals and healthcare systems. This condition adversely affects health-related quality of life and leads to escalated healthcare expenses due to an increase in office visits, referrals to specialists, and hospital admission. This study aimed to evaluate the prevalence, recognition, risk factors, and course of constipation among hospitalized patients in medical wards. Materials and Methods: A prospective study was conducted, including all adult patients admitted to the General Medicine Unit between 1 February 2022 and 31 August 2022. Constipation was identified using the Constipation Assessment Scale (CAS), and relevant factors were extracted from the patients' medical records. Results: Among the patients who met the inclusion criteria (n = 556), the prevalence of constipation was determined to be 55.6% (95% CI 52.8-58.4). Patients with constipation were found to be older (p < 0.01) and had higher frailty scores (p < 0.01). Logistic regression analysis revealed that heart failure (Odds ratio (OR) 2.1; 95% CI 1.2-3.7; p = 0.01), frailty score (OR 1.4; 95% CI 1.2-1.5; p < 0.01), and dihydropyridines calcium channel blockers (OR 1.8; 95% CI 1.2-2.8; p < 0.01) were independent risk factors for constipation. Furthermore, the medical team did not identify constipation in 217 patients (64.01%). Conclusions: Constipation is highly prevalent among medically hospitalized patients. To ensure timely recognition and treatment, it is essential to incorporate a daily constipation assessment scale into each patient's medical records.

Death by fecaloma

A 59-year-old man with a history of cerebral palsy and dextroscoliosis died in a group home. He required supplemental oxygen and had no bowel movement for weeks prior to death. At autopsy, the abdomen was markedly distended and there were flexion contractures of the legs. Postmortem computed tomography revealed a dilated digestive tract and fecal loading in the sigmoid and rectum, marked upwardly displaced diaphragm and scoliosis. On internal examination, the diaphragm was displaced rostrally and the rectosigmoid colon contained 2.5 kg of fecaloma with two rectal fecaliths. Severe scoliosis with marked reduction in volume of thoracic cavity was present. Microscopic examination revealed chronic aspiration pneumonia and chronic pulmonary hypertension. Overall, four factors led to respiratory failure: fecaloma; cerebral palsy; scoliosis; and chronic aspiration pneumonia. Based on clinicopathological correlation, the cause of death was determined to be a combination of these factors, and the key acute factor was the fecaloma.

Hypoxia and chest pain due to acute constipation: an underdiagnosed condition?

An obese, previously healthy, 10-year-old boy presented with acute respiratory distress, chest, and abdominal pain. He was hypoxic and dyspneic in the emergency room. The abdomen was distended and tender, and the rectum was full of hard stool. Following catharsis, he made a complete recovery with resolution of all clinical signs. A review of the literature reveals that acute constipation as a cause of hypoxia and respiratory distress has been recognized, but has rarely been reported. We believe that this is a common phenomenon but probably infrequently recognized.
