The Challenge of Pneumatosis Intestinalis: A Contemporary Systematic Review

PURPOSE

Pneumatosis intestinalis is a radiological finding with incompletely understood pathogenesis. To date, there are no protocols to guide surgical intervention.

METHODS

A systematic review of literature, according to PRISMA criteria, was performed. Medline and PubMed were consulted to identify articles reporting on the items "emergency surgery, pneumatosis coli, and pneumatosis intestinalis" from January 2010 up to March 2022. This study has not been registered in relevant databases.

RESULTS

A total of 1673 patients were included. The average age was 67.1 ± 17.6 years. The etiology was unknown in 802 (47.9%) patients. Hemodynamic instability (246/1673-14.7% of the patients) was associated with bowel ischemia, necrosis, or perforation (p = 0.019). Conservative management was performed in 824 (49.2%) patients. Surgery was performed 619 (36.9%) times, especially in unstable patients with bowel ischemia signs, lactate levels greater than 2 mmol/L, and PVG (p = 0.0026). In 155 cases, surgery was performed without pathological findings.

CONCLUSIONS

Many variables should be considered in the approach to patients with pneumatosis intestinalis. The challenge facing the surgeons is in truly identifying those who really would benefit and need surgical intervention. The watch and wait policy as a first step seems reasonable, reserving surgery only for patients who are unstable or with high suspicion of bowel ischemia, necrosis, or perforation.

Clostridium perfringens gas gangrene caused by closed abdominal injury: A case report and review of the literature

BACKGROUND

Abdominal Clostridium perfringens (C. perfringens) gas gangrene is a rare infection that has been described in the literature as most frequently occurring in postoperative patients with open trauma. Intra-abdominal gas gangrene caused by C. perfringens infection after closed abdominal injury is extremely rare, difficult to diagnose, and progresses rapidly with high mortality risk. Here, we report a case of C. perfringens infection caused by closed abdominal injury.

CASE SUMMARY

A 54-year-old male suffered multiple intestinal tears and necrosis after sustaining an injury caused by falling from a high height. These injuries and the subsequent necrosis resulted in intra-abdominal C. perfringens infection. In the first operation, we removed the necrotic intestinal segment, kept the abdomen open and covered the intestine with a Bogota bag. A vacuum sealing drainage system was used to cover the outer layer of the Bogota bag, and the drainage was flushed under negative pressure. The patient was transferred to the intensive care unit for supportive care and empirical antibiotic treatment. The antibiotics were not changed until the results of bacterial culture and drug susceptibility testing were obtained. Two consecutive operations were then performed due to secondary intestinal necrosis. After three definitive operations, the patient successfully survived the perioperative period. Unfortunately, he died of complications related to Guillain-Barre syndrome 75 d after the first surgery. This paper presents this case of intra-abdominal gas gangrene infection and analyzes the diagnosis and treatment based on a review of current literature.

CONCLUSION

When the intestines rupture leading to contamination of the abdominal cavity by intestinal contents, C. perfringens bacteria normally present in the intestinal tract may proliferate in large numbers and lead to intra-abdominal infection. Prompt surgical intervention, adequate drainage, appropriate antibiotic therapy, and intensive supportive care comprise the most effective treatment strategy. If the abdominal cavity is heavily contaminated, an open abdominal approach may be a beneficial treatment.

Iatrogenesis in the Context of Residential Dementia Care: A Concept Analysis

Background and Objectives

This concept analysis aims to explore iatrogenesis within the context of residential dementia care and to distinguish this phenomenon from similar phenomena, such as abuse and inadvertent harm.

Research Design and Methods

Walker and Avant's method for concept analysis was used to define critical attributes of iatrogenesis within residential dementia care, and to explore antecedents and consequences of its occurrence. A review of the literature about iatrogenesis in the context of residential dementia was conducted across 4 electronic databases. Texts about iatrogenesis in surgery, medicine, social work, psychology, and other relevant disciplines were also reviewed to provide additional context for the concept.

Results

Iatrogenesis takes a unique form in residential dementia care. The final definition of the concept proposed in this article is habituated, forceful, hands-on care provided to residents who exhibit responsive behaviors that result in emotional, physical, spiritual, social harm, and/or gradual functional decline, that is provided with the intention of supporting the resident's safety and dignity.

Discussion and Implications

The definition of iatrogenesis proposed in this article is an initial step toward developing evidence-based practice for the provision of nonconsensual assistance in residential dementia care. A theoretical definition like the one proposed in this article may serve as a starting point for the operationalization of the concept, which would promote future empirical research into staff and residents' experiences of health care-inflicted harms in this context. Theoretically, it contributes to critical conversations about the narratives, myths, and misperceptions that facilitate the provision of nonconsensual care.
