Clozapine-induced stercoral colitis: a surgical perspective

Clozapine-Induced Refractory Colonic Pseudo-Obstruction

The management of treatment-resistant schizophrenia (TRS) is challenging as the medications involved, often atypical antipsychotics, have a host of associated adverse effects. While complications such as agranulocytosis are well established and necessitate close hematological monitoring, the gastrointestinal effects of particular atypical antipsychotics, such as clozapine, are recognized to a lesser extent. The following case of TRS leading to chronic treatment-resistant pseudo-obstruction, eventually requiring total colectomy, highlights the considerable sequelae of clozapine on the gastrointestinal tract. Beyond the effects of severe constipation, the possible implications of ischemic colitis, stercoral perforation, and intraabdominal sepsis warrant a degree of caution when prescribing such medication. This study sheds light on the importance of monitoring bowel motility when administering antipsychotics, particularly clozapine, to avoid these deleterious consequences.

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.

Mission Disimpaction: Endoscopic Management of Stercoral Colitis in an Adolescent

Stercoral colitis is a rare entity of inflammatory colitis with high morbidity and mortality attributable to colonic fecaloma impaction, often a result of chronic constipation. Despite demographic imbalance favoring elders, children hold comparative risk factors for chronic constipation. Suspicion for stercoral colitis is warranted in nearly every stage of life. Computerized tomography (CT) is diagnostic for stercoral colitis, where radiological findings correlate to high sensitivity and specificity. Difficulty exists discerning from other acute and chronic intestinal etiologies with overlapping nonspecific symptoms and laboratory markers. Management involves prompt risk assessment for perforation and immediate disimpaction to avoid ischemic injury, with endoscopic directed disimpaction standard of care for nonoperative measures. Our case describes stercoral colitis in an adolescent with contributive risk factors for fecaloma impaction and is one of the first adolescent case reports involving successful endoscopic management.

Non-perforated Stercoral Colitis patients with septic shock have a higher mortality than their perforated counterparts. A case report and review of literature

Introduction and importance

Stercoral colitis is an inflammatory condition caused by fecal impaction; it involves the colonic or rectal wall. It occurs most commonly in nursing home patients, chronic opioid users, and patients with mental impairment.

Case presentation

We present the case of a 36-year-old, obese, African American male with a history of intellectual disability, bipolar disorder, and chronic constipation. Patient presented to the emergency room after an episode of syncope, confusion, 24-hour abdominal pain, nausea, and vomiting. On admission to the ED the patient was found to be in sepsis; within 4 h he developed septic shock. CT scan of the abdomen showed impacted fecal matter in a significantly distended left and sigmoid colon. This was associated with colitis, extensive fat stranding and free fluid, without pneumoperitoneum. The patient was taken to the operating room for exploration where he underwent an extended left colectomy and Hartmann's procedure. Pathology showed acute focal colitis with transmural necrosis. There were no signs of perforation or inflammatory bowel disease. The patient recovered and was discharged home on post-operative day 8. Upon follow up on post-operative day 22, he was doing well.

Clinical discussion

This case illustrates a very rare and challenging scenario. Complications of stercoral colitis include: stercoral ulcer, perforation, ischemic colitis, sepsis and death. Peritonitis, sepsis and bowel necrosis without perforation is extremely rare with very few cases reported in the literature. Colectomy with diversion is the mainstay of therapy.

Conclusion

It is of paramount importance for ED providers and general surgeons to be aware of this condition. It presents a diagnostic challenge and carries an elevated mortality. Elderly patients on chronic opioids and those with mental impairment are at a higher risk.

•

Stercoral colitis induced sepsis is a challenging diagnosis.

•

Stercoral colitis induced sepsis has a mortality close to 60 %.

•

Source control is paramount to avoid fatal outcomes.

Antipsychotic-Induced Constipation: A Review of the Pathogenesis, Clinical Diagnosis, and Treatment

Antipsychotic-induced gastrointestinal hypomotility and, in particular, its manifestation of constipation are common adverse effects in patients with schizophrenia in clinical practice. Serious complications of antipsychotic-induced constipation include ileus, ischaemic bowel disease, colon perforation, aspiration pneumonia, and bacterial septicaemia, which can be life threatening if left untreated, especially in patients prescribed clozapine. The aim of this paper is to review the latest research on the epidemiology, clinical examination methods, pathophysiology, and treatment options and preventive measures for antipsychotic-induced constipation. While clinicians are normally aware of the overall side effects caused by antipsychotics, constipation is often an under-recognized condition despite its relatively high incidence and its impact on daily living. The incidence of constipation differs among individual antipsychotics, but more than 50% of patients prescribed antipsychotics suffer from constipation. Limited fluid intake, poor dietary habits, and a sedentary lifestyle can also worsen constipation. The mechanisms of antipsychotic-induced constipation may be antagonism of cholinergic, histaminergic, and serotonergic receptors, with both parent drug and metabolite(s) contributing to the effects on gastrointestinal motility. Numerous methods, mainly divided into scale evaluations and objective examinations, are applied to evaluate antipsychotic-induced constipation; however, objective examinations have a greater ability to identify cases of gastrointestinal hypomotility since there is often an under-reporting of symptoms in subjective reporting and scale evaluation due to a higher pain threshold, an inability to express pain sensations, and a lack of symptom awareness in these patients. Antipsychotic drug-induced constipation should be closely monitored in patients receiving these medications, with timely intervention to avoid serious gastrointestinal consequences. There is currently no consensus on the efficacy of laxatives in these patients. Further in-depth studies should explore the underlying mechanisms and devise optimal therapeutic approaches to minimize constipation during antipsychotic treatment.

Did we do everything we could have? Nurses' contributions to medicines optimization: A mixed-methods study

AIM

To explore UK professionals' interpretations of medicines optimization and expansion of nurses' roles.

DESIGN

This mixed-methods study sought professionals' views on nurses' involvement, competency and engagement in monitoring patients for adverse effects of medicines, monitoring adherence, prescribing and patient education.

METHOD

An online survey and interviews were undertaken with nurses, doctors and pharmacists in Wales and England, May 2018 to July 2019.

RESULTS

In all, 220 nurses, 17 doctors and 62 pharmacists responded to the online survey, and 24 professionals were interviewed. Nurses were divided over extending their roles, with 123/220 (55.9%) wishing to extend roles in monitoring patients for possible adverse drug reactions (ADRs), 111/220 (50.5%) in adherence monitoring, 121/220 (55.0%) in prescribing and 122/220 (55.4%) in patient education. The best-qualified nurses were the most willing to increase involvement in monitoring patients for ADRs (aOR 13.00, 1.56-108.01). Interviews revealed that both nurses and doctors assumed the other profession was undertaking this monitoring. Respondents agreed that increasing nurses' involvement in medicines optimization would improve patient care, but expressed reservations about nurses' competencies. Collaboration between nurses and doctors was suboptimal (rated 7/10 at best) and between nurses and pharmacists even more so (6/10 at best).

CONCLUSION

Juxtaposition of datasets identified problems with medicines optimization: although most respondents agreed that increasing nurses' involvement would positively impact practice, their educational preparation was a barrier. Only ~50% of nurses were willing to expand their roles to fill the hiatus in care identified and ensure that at least one profession was taking responsibility for ADR monitoring.

IMPACT

To improve multiprofessional team working and promote patient safety, nurse leaders should ensure patients are monitored for possible ADRs by at least one profession. Initiatives expanding nurses' roles in medicines optimization and prescribing might be best targeted towards the more educated nurses, who have multidisciplinary support.

Stercoral Colitis in a Patient With Pediatric-Onset Systemic Lupus Erythematosus: Case Analysis and Review of the Literature

Systemic lupus erythematosus (SLE) is an autoantibody-related disease that affects multiple organs. Stercoral colitis (SC) is a rare type of inflammatory colitis with a high mortality rate. Here, we report the first case of pediatric-onset lupus in a case complicated by stercoral colitis. We also conducted a literature review of patients with SC under 30 years old to provide useful clues for rapid diagnosis at a young age. A 28-year-old female with a history of lupus and neuropsychiatric SLE was admitted with severe abdominal pain. She was found to have stercoral colitis during surgery. Two years later, the patient underwent Hartman's operation due to ischemia of the colon. In addition, 10 patients younger than 30 years old with a diagnosis of SC were analyzed based on clinical presentation, physical examination, laboratory exam, imaging and treatment. All cases had a favorable outcome without mortality. Stercoral colitis is a rare but lethal complication, emphasizing the importance of a multidisciplinary approach. Differential diagnosis should include stercoral colitis for patients with SLE developing unexplained sharp abdominal pain.
