It is often regarded as well-tolerated, non-invasive, and safe across all age groups, with the main, albeit rare, complication of retention of the capsule, normally in the small bowel or lower gastrointestinal (GI) tract. Retention in the upper GI tract is extremely rare; here, we present a case of a 94-year-old who experienced capsule retention in a previously undiagnosed pharyngeal pouch. This appears to be the first case report detailing video capsule retention in a pharyngeal pouch involving a patient of such an advanced age, and in which endoscopic retrieval was not necessitated. The learning here is that patients should be evaluated for prior medical history or the possibility of a pharyngeal pouch before performing VCE.  \nKey Words: Geriatrics, Capsule endoscopy, Zenker diverticulum  \nINTRODUCTION  \nVideo capsule endoscopy (VCE) is a non-invasive and well-tolerated investigative modality that provides endoluminal imaging of the small bowel.1) Common indications include investigation of unexplained gastrointestinal (GI) bleeding, unexplained iron deficiency anaemia, and evaluation for and monitoring of, Crohn’s disease.2) In the instances ofthe first and second indications, VCE normally follows diagnostically unyielding upper and lower GI tract endoscopies.3)  \nRetention of the video capsule is the main adverse event and generally occurs in the small bowel or lower GI tract, and is defined as failure of the capsule to pass through the GI tract after 2 weeks of ingestion.1) The incidence of this complication is reportedly low, occurring in only 1%–2% of cases; however, this figure can be as high as 4%–13% in patients with inflammatory bowel disease, in which they are more susceptible to stricture formation.4,5) Older age alone is not recognised as a risk factor.4)  \nRetention of the capsule in the upper GI tract is reportedly extremely rare. A 2023 literature review by Arzivian et al.1) noted that there are only a small handful of case reports describing capsule re-  \ntention in the upper GI tract. Within these, all 12 of the described patients were older adults with a median age of 75.8 years. American and Canadian guidelines on VCE contraindications mention swallowing and motility disorders ofthe upper GI tract, but do not specifically reference the presence of a pharyngeal pouch.6,7)  \nWe present here a unique case of a 94-year-old patient who hada video capsule become lodgedin her upper GI tract, in anundiagnosed pharyngeal pouch, during an acute hospital admission with a GI bleed. The capsule migrated within 24 hours with conservative management.  \nCASE REPORT  \nA 94-year-old woman with a medical history of osteoporosis and transient ischaemic attack presented to our emergency department from a care home following a syncopal episode while on the commode. Of note, her carers had noted black coloured stools in the commode pan. Her medications included denosumab, aspirin and calcium-vitamin D supplements.  \nOn examination in the emergency department, she was alert, and her vital signs included a blood pressure of 102/64 mmHg,  \n© 2025 by The Korean Geriatrics Society  \nThis is an open access article distributed under the terms of the Creative Commo","cbCaieNz1jpqYyCz","https://ap.wps.com/l/cbCaieNz1jpqYyCz","pdf",273439,"English","# Introduction\n## Video capsule endoscopy and indications\n## Definition and risk of capsule retention\n## Upper GI retention rarity\n# Case Report","[{\"question\":\"What is video capsule endoscopy (VCE) used for?\",\"answer\":\"VCE provides endoluminal imaging of the small bowel.
