The necessity of pyloroplasty after esophagectomy and gastric pull-up is debated. Disadvantages of a standard pyloroplasty include the potential for leak, shortening of the length of the graft, and complexity when done during a minimally invasive procedure. The aim of this study is to report our experience with a novel internal pyloroplasty technique using a circular stapler (CS pyloroplasty), which is applicable for both laparoscopic and open esophagectomy. The records of all patients who underwent an esophagectomy with gastric pull-up and pyloroplasty between 2002 and 2007 were reviewed. The CS pyloroplasty was performed through a lesser curve gastrotomy with a 21-mm CS, while the standard pyloroplasty entailed a longitudinal full thickness incision through the pylorus with mucosal closure in the same direction and a Graham patch. A CS pyloroplasty was performed in 144 and a standard pyloroplasty in 133 patients. The median patient age was 66years, and the median follow-up was 17months, and was similar for both types of pyloroplasty. Routine postoperative videoesophagram was significantly more likely to show a delay in contrast transit through the pylorus after standard pyloroplasty (16% standard vs. 8% CS pyloroplasty, P= 0.03). Significantly more patients had postoperative endoscopy after standard pyloroplasty (40% standard vs. 24% CS pyloroplasty, P= 0.004), but the frequency of pyloric dilatation was similar. There were no leaks with either technique. A circular stapled pyloroplasty is as efficacious as a standard pyloroplasty after esophagectomy with gastric pull-up. Potential advantages include the ease and simplicity of the procedure along with virtually no risk of a leak and no graft shortening. The technique is amenable to both open and minimally invasive procedures.
