Abstract
Abstract Background Malignant oesophageal strictures can cause airway compromise and fistula formation. Combined oesophageal and airway stenting is a potential treatment yet no guidelines exist. This study aims to describe the outcomes of same-session oesophageal and airway endoscopic stenting for malignant strictures and propose an algorithm for intervention. Methods A retrospective study on patients undergoing same-session gastroenterology (GI) and respiratory endoscopy at University College London Hospital, 2019-2023. All procedures were with anaesthetic-led propofol sedation. Endoscopic decision making was based on pre-procedure multidisciplinary team meeting (MDM) and intra-procedure clinical assessment. Data collected included malignancy type, luminal narrowing, complications, and mortality. Results 26 patients were identified. Mean age was 63 years. Cancer type was oesophageal (81%) or lung (19%). The most common referral indication was dysphagia (42%); airway compromise was often seen on imaging (65%). Stent insertion was oesophageal only (35%), airway only (19%) and dual (27%). Airway stenting was common (80%) if airway stenosis was >50%. No airway stenting occurred if stenosis was <50%. After oesophageal stenting, repeat bronchoscopy showed increased airway stenosis in 4 patients (25%). The only intraoperative complication was one oesophageal perforation. New tracheooesophageal fistula was the most common post-intervention complication (15%). Median time from malignancy diagnosis to death was 7.9 weeks. Conclusion We present the first algorithm (Figure 1) for endoscopic stenting in patients with malignant oesophageal stricture and airway involvement. We suggest upper GI and respiratory MDM to plan same-session endoscopy with decision-making framed by patient-centred goals given their poor prognosis.
