314. TRANSORAL ANTEGRADE T-TUBE INSERTION FOR MANAGEMENT OF OESOPHAGEAL LEAKS FOLLOWING MINIMAL INVASIVE OESOPHAGECTOMY

Abstract Introduction Oesophageal leaks following minimal invasive oesophagectomy (MIE) present significant challenges to upper GI surgeons, with reported rates ranging from 11% to 21%. Management strategies include: conservative, endoscopic, and surgical interventions. These vary based on patient clinical status and institution. Here, we propose a hybrid approach involving thoracoscopic washout coupled with antegrade T-tube insertion via gastroscopy for managing these complex leaks. Methods We describe the case of a 66-year-old male who underwent MIE via the McKeown approach for Siewert 1 Gastro-oesophageal adenocarcinoma. His neoadjuvant chemotherapy had been interrupted by a complex ischiorectal abscess and thus a decision was made to proceed for surgery. The surgery proceeded with a cervical anastomosis using a linear stapled technique and closure with 3.0 PDS. Postoperatively, the patient deteriorated on day 2, necessitating intubation due to decreased oxygen saturation. The chest tube output looked slightly bile stained. A subsequent CT scan revealed mediastinal fluid accumulation, prompting urgent intervention. Results Diagnostic thoracoscopy revealed contamination of the right chest and posterior mediastinum, necessitating extensive washout. A 2cm necrotic patch and perforation were identified on the gastric side of the oesophago-gastric anastomosis. Intraoperative gastroscopy localized the leak with a positive air bubble test. A Maryland forceps was passed through the defect to confirm the defect. Subsequently, a guidewire was passed antegrade into the cavity using the gastroscope. Decision was made to purse-string the defect (around the guidewire) using 3.0 PDS and the T-tube was exchanged transorally via the guidewire into the cavity and exteriorized through a 5mm port to the skin. Existing large-bore chest and Blake drains were retained, and a feeding jejunostomy was established. Conclusion This hybrid management approach, combining endoscopy and thoracoscopic washout with T-tube insertion, offers an alternative for addressing complex anastomotic leaks following MIE. By avoiding resection and diversion, this technique potentially reduces morbidity. Follow-up scans demonstrated resolution of the leak allowing the patient to be discharged. https://1drv.ms/v/s!Aghd8kXfo8oQlX6QyliVLgRDmIu-?e=EGN5YD
