The aetiology of pouchitis in patients with inflammatory bowel disease.

Restorative proctocolectomy with ileal pouch-anal anastomosis is a treatment option for patients with refractory ulcerative colitis. Pouchitis is the most common complication, representing a spectrum of diseases ranging from acute antibiotic-responsive type to chronic antibiotic-refractory. Early accurate diagnosis using a combined assessment of symptoms, endoscopy and histology is important for both treatment and prognostication. Most patients respond well to antibiotic therapy; however, management of chronic antibiotic-refractory pouchitis remains a challenge, and treatment options are based on small studies. Pouchitis is thought to be driven by the interaction between genetics, the immune system and the environment but as yet a causal relationship has yet to be identified. Further longitudinal assessment of the pouch integrating new technologies may help us understand the factors driving pouchitis. This review outlines the currently understood risk factors and aetiology of pouchitis.

Management of foreign body ingestion in adults: Time to STOP and rethink endoscopy.

Background and study aims Foreign body ingestion is a common cause for Emergency Department presentation. In adults, foreign body ingestion is more common in patients with underlying psychiatric comorbidity, the elderly, alcohol intoxication, and in prisoners. This study reviewed the management of patients presenting to a tertiary hospital with foreign body ingestion. Patients and methods A retrospective review of patients presenting with foreign body ingestion to a tertiary hospital in Melbourne, Victoria, was undertaken from January 2017 to December 2021. Data collected included patient demographics, type of foreign body, length of stay, imaging modalities, management strategies, and complications. High-risk ingestion was defined as sharp objects, length >5 cm, diameter >2.5 cm, button battery and/or magnet ingestion or esophageal as per international guidelines. Results A total of 157 presentations by 63 patients with foreign body ingestion occurred between 2017 and 2021 (50% male; median age 30 years). Of the patients, 56% had underlying psychiatric comorbidities. The majority of presentations occurred in prisoners (65%). The most commonly ingested objects were batteries (23%), alleged drug-containing balloons (17%), razor blades (16%), and miscellaneous (40%). High-risk ingestion occurred in approximately two-thirds of presentations. Conservative management was the most common approach in 55% of patients. Complications, defined as perforation, bowel obstruction or fistula formation, did not occur in this cohort despite more than half presenting with high-risk ingestions. Thirty-day re-presentation rates were high (31%) and that was most common in patients with intentional ingestion, underlying mental health disorders, and a documented history of self-harm. Conclusions Conservative management for patients presenting with recurrent high-risk foreign body ingestion was safe in appropriately selected cases. Re-presentation is common and poses significant challenges for health care providers.
