Clinical effect and learning curve of endoscopic two-way catheterization on anastomotic fistula after esophageal cancer surgery

Objective To investigate the clinical effect of endoscopic two-way catheterization in the treatment of anastomotic fistula after esophageal cancer surgery. Methods From August 2017 to October 2020, 211 patients with postoperative anastomotic fistula of esophageal cancer treated in Zhongshan People's Hospital were selected for retrospective study. The 105 patients treated with routine intravenous nutritional support and gastrointestinal decompression were served as control group. The 106 patients placed with fistula drainage tube to the fistula mouth and three lumen nutritional tube to the jejunum under endoscopy was served as observation group. The fistula healing time, recovery eating time, hospital stays, clinical cure rate of the anastomotic fistula, nutritional status indexes(prealbumin, albumin, hemoglobin and transferrin) and the quality of life(SF-36 scale) were compared between two groups. According to CUSUM method, all cases were divided into learning improvement stage(n=60) and mastery stage(n=46),
