ObjectiveTo investigate the method and effect of transoral use of circular stapler to connect upper anastomotic stoma in reconstruction of digestive tract.MethodsClinical data of 7 patients suffering from hypopharyngeal carcinoma undergoing surgical removal and receiving reconstruction of postoperative oropharyngeal defects with circular stapler transorally in our department from March 2016 to Dec 2018 were analyzed retrospectively.ResultsNeither pharyngeal fistula nor upper anastomotic stenosis was found in all cases. One patient died of lung metastasis 19 months after surgery and one had lower anastomotic stenosis 9 months after surgery.ConclusionsIn the reconstruction of the digestive tract after surgical removal of hypopharyngeal carcinoma, circular stapler can be inserted transorally to anastomose the upper end of the digestive tract with good effect. The incidences of anastomotic fistula and upper anastomotic stenosis are lower than those of manual suture, with advantages of timesaving and reliability. More clinical explorations are needed to determine the indications and contraindications of transoral use of circular stapler.
