Abstract
A prospective, randomized, controlled trial comparing clinical outcome and emptying of a solid meal from the retrosternal stomach, with and without pyloroplasty is described. Forty consecutive patients with oesophageal cancer undergoing retrosternal gastric reconstruction of the oesophagus were studied. In 20 patients the pylorus was left intact (group 1) and 20 patients underwent an Aust1 pyloroplasty (group 2). Nine patients in group 1 suffered postoperative symptoms of gastric stasis compared with only one patient in group 2 (P = 0·0106). Three patients in group 1 died from aspiration pneumonia before discharge from hospital. A gastric emptying test was performed on 24 patients between 1 and 3 months after surgery. By this time, most survivors had recovered from symptoms attributed to gastric stasis and no significant difference in gastric emptying could be demonstrated between the two groups. Selection of patients, a wide range of emptying times and improvement in gastric emptying on follow‐up may explain the lack of correlation between postoperative symptomatology and the gastric half‐emptying times. A pyloroplasty is advised to prevent the potentially lethal effects of gastric stasis in the early postoperative period following retrosternal reconstruction of the oesophagus.
