Objectives: In expert hands, the intrathoracic oesophago-gastric anastamosis usually provides a low rate of strictures and leaks. However, anastomoses can be technically challenging and time consuming when minimally invasive techniques are used. We present our preliminary results of a standardised 25 mm/4.8 mm circular-stapled anastomosis using a trans-orally placed anvil. Materials and methods: We evaluated a prospective cohort of 37 consecutive patients offered minimally invasive Ivor Lewis oesophagectomy at a tertiary referral centre. The oesophagogastric anastomosis was created using a 25-mm anvil (Orvil, Autosuture, Norwalk, CT, USA) passed trans-orally, in a tilted position, and connected to a 90-cm long polyvinyl chloride delivery tube through an opening in the oesophageal stump. The anastomosis was completed by joining the anvil to a circular stapler (end-to-end anastomosis stapler (EEA XL) 25 mm with 4.8-mm staples, Autosuture, Norwalk, CT, USA) inserted into the gastric conduit. Primary outcomes were leak and stricture rates. Results: Thirty-seven patients (mean age 65 years) with distal oesophageal adenocarcinoma (n = 29), squamous cell cancer (n = 5) or high-grade dysplasia in Barrett's oesophagus (n = 3) underwent an Ivor Lewis oesophagectomy between October 2007 and August 2009. The abdominal portion was operated laparoscopically in 30 patients (81.1%). The thoracic portion was done using a muscle-sparing mini-thoracotomy in 23 patients (62.2%) and thoracoscopic techniques in 14 patients (37.8%). There were no intra-operative technical failures of the anastomosis or deaths. Five patients had strictures (13.5%) and all were successfully treated with endoscopic dilations. One patient had an anastomotic leak (2.7%) that was successfully treated by re-operation and endoscopic stenting of the anastomosis. Discussion: The circular-stapled anastomosis with the trans-oral anvil allows for an efficient, safe and reproducible anastomosis. This straightforward technique is particularly suited to the completely minimally invasive Ivor Lewis oesophagectomy.
