To assess the factors contributing to the technical and clinical success of oesophageal stenting
Material(s) and Method(s):
Retrospective single centre study of all patients whom underwent oesophageal stenting from 2011 to 2018 was collected. Information for analysis was gathered with the use of RIS/PACS, histopathology records, patient clinical notes and ICE. Pathology subtype, location of lesion and types of stents used were also collected. Complications and rates of re-intervention within 30 days (immediate) and up to a year (long-term) within the procedure were evaluated. Average survival rates from insertion as well as 30-day and overall 1-year survival were analysed.
Among 392 patients with oesophageal malignancy, less than 1% had immediate or long term complications. Among 31 patients with other cancers, no immediate or late complication was recorded. Among 23 patients with benign strictures, 9% reported immediate and long term complications. Among 5 patients with post-operative oesophageal leakage, 3 reported immediate complications and one long term complication. No procedure-related deaths recorded within our patient cohort. Average time to death after palliative oesophageal stenting was 5 months for patients with oesophageal cancer and 2 months for other cancers. The technical success of oesophageal stenting was 100%, with only 2% of patients requiring re-intervention at 30 days and less than 1% at 1 year.
Oesophageal stenting is a safe procedure for the palliation of dysphagia caused by advanced oesophageal cancer or malignant extrinsic compression of the oesophagus. In our experience there is minimal post-procedural complication and mortality, which is comparable with published studies.
