Experiences with the EEA stapling instrument for anastomoses of the upper gastrointestinal tract

Abstract

Technique, early experiences and results with the EEA stapling instrument for the reconstruction of intestinal continuity after gastric and esophageal resection in 52 patients are reported. 12 patients with gastric cancer and 4 patients with cardiac cancer underwent total gastrectomy with esophagojejunostomy, 25 patients with gastric cancer underwent subtotal gastrectomy with gastrojejunostomy, 8 patients with esophageal cancer had esophageal resection with esophagogastrostomy and 3 patients with non-resectable gastric or cardiac cancer had palliative by-passing esophagojejunostomy, all performed by means of the EEA stapler. Three anastomotic leakages were detected radiologically, two after esophagojejunostomy and one after gastrojejunostomy. These leaks did not lead to clinical signs or symptoms and healed with parenteral nutrition in three weeks. One patient died of myocardial infarction on the 8th postoperative day, but at autopsy the anastomosis was intact. At follow-up endoscopy three mild anastomotic strictures have been found, but no treatment have been required. In two patients the stricture resolved spontaneously in a few months. According to our experience, esophagojejunal, gastrojejunal and esophagogastric anastomosis performed with the EEA stapling instrument seems to be at least as reliable as a hand sutured anastomosis, obviously even more reliable. The EEA stapler is also time saving, especially after adequate experience with the use of the instrument has been achieved. The difficulties and hazards associated with the use of the stapler are discussed.
