Transnasal endoscopy: moving from endoscopy to the clinical outpatient-blue sky thinking in oesophageal testing. Frontline Gastroenterol 2022; 13:e65-e71. [PMID: 35812036 PMCID: PMC9234731 DOI: 10.1136/flgastro-2022-102129] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Accepted: 05/03/2022] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND COVID-19 has severely affected UK endoscopy services with an estimate 86% loss of activity during the first wave. Subsequent delays in diagnostic and surveillance procedures highlight the need for novel solutions to tackle the resultant backlog. Transnasal endoscopy (TNE) provides an attractive option compared with conventional upper gastrointestinal endoscopy given its limited use of space, no sedation and reduced nursing resources. OUR EXPERIENCE We describe piloting and then establishing an outpatient model TNE service in the pandemic era and the implications on resource allocation, training and workforce. We also discuss our experiences and outline ways in which services can evolve to undertake more complex endoscopic diagnostic and therapeutic work. Over 90% of patients describe no discomfort and those who have previously experienced conventional transoral endoscopy preferred the transnasal approach. We describe a low complication rate (0.8%) comprising two episodes of mild epistaxis. The average procedure duration was reasonable (9.9±5.0 min) with full adherence to Joint Advisory Group quality standards. All biopsies assessed were deemed sufficient for diagnosis including those for surveillance procedures. DISCUSSION TNE can offer a safe, tolerable, high-quality service outside of a conventional endoscopy setting. Expanding procedural capacity without impacting on the current endoscopy footprint has great potential in recovering endoscopy services following the COVID-19 pandemic. Looking forward, TNE has potential to be used both within the endoscopy suite as part of therapeutic procedures, or outside of the endoscopy unit in outpatient clinics, community hospitals, or mobile units and to achieve this in a more sustainable and environmentally friendly way.

Dig Dis Sci 2022; 67:1937-1947. [PMID: 35239094 PMCID: PMC8893049 DOI: 10.1007/s10620-022-07432-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Accepted: 01/30/2022] [Indexed: 12/23/2022]
Abstract
Diagnostic unsedated transnasal endoscopy (uTNE) has been proven to be a safe and well-tolerated procedure. Although its utilization in the United Kingdom (UK) is increasing, it is currently available in only a few centers. Through consideration of recent studies, we aimed to perform an updated review of the technological advances in uTNE, consider their impact on diagnostic accuracy, and to determine the role of uTNE in the COVID-19 era. Current literature has shown that the diagnostic accuracy of uTNE for identification of esophageal pathology is equivalent to conventional esophagogastroduodenoscopy (cEGD). Concerns regarding suction and biopsy size have been addressed by the introduction of TNE scopes with working channels of 2.4 mm. Advances in imaging have improved detection of early gastric cancers. The procedure is associated with less cardiac stress and reduced aerosol production; when combined with no need for sedation and improved rates of patient turnover, uTNE is an efficient and safe alternative to cEGD in the COVID-19 era. We conclude that advances in technology have improved the diagnostic accuracy of uTNE to the point where it could be considered the first line diagnostic endoscopic investigation in the majority of patients. It could also play a central role in the recovery of diagnostic endoscopic services during the COVID-19 pandemic.

Abstract
Background Percutaneous endoscopic gastrostomy is a commonly used endoscopic technique where a tube is placed through the abdominal wall mainly to administer fluids, drugs and/or enteral nutrition. Several placement techniques are described in the literature with the ‘pull’ technique (Ponsky-Gardener) as the most popular one. Independent of the method used, placement includes a ‘blind’ perforation of the stomach through a small acute surgical abdominal wound. It is a generally safe technique with only few major complications. Nevertheless these complications can be sometimes life-threatening or generate serious morbidity. Method A narrative review of the literature of major complications in percutaneous endoscopic gastrostomy. Results This review was written from a clinical viewpoint focusing on prevention and management of major complications and documented scientific evidence with real cases from more than 20 years of clinical practice. Conclusions Major complications are rare but prevention, early recognition and popper management are important.
