    Abstract:
    OBJECTIVE: The use of a circular stapler in cervical esophagogastric anastomosis remains controversial. This study was to compare the postoperative and long-term results of manual and mechanical techniques for cervical esophagogastric anastomosis after resection for squamous cell carcinoma. METHODS: A prospective randomized controlled trial was undertaken in 63 patients with curatively resectable squamous cell cancer of the thoracic esophagus between 1996 and 1999. Patients were randomized to receive either a hand-sewn (32 patients) or circular stapled (31 patients) cervical esophagogastric anastomosis. RESULTS: The mean operating time was longer when the hand-sewn method was used (524 vs. 447 min, P < 0.001). Anastomotic leakage was noted in seven patients (22%) in the hand-sewn group and eight patients (26%) in the stapler group (P = NS). Hospital mortality occurred in four patients (13%) of the hand-sewn group and in three patients (10%) of the stapler group (P = NS). After the operation, four patients (14%) in the hand-sewn group and five patients (18%) in the stapler group developed a benign esophageal stricture (P = NS). The mean follow-up time was 24 months, and the rates of freedom from benign stricture and survival were comparable in each group. CONCLUSIONS: Performing cervical esophagogastric anastomoses using a circular mechanical stapler had a shorter operating time and a comparable outcome to the hand-sewn method. The circular mechanical stapler could be used as an alternative for cervical esophagogastric anastomosis after resection for esophageal squamous cell cancer.
