Intraoperative Pyloric Dilation After Esophagectomy: Promising, but Unproven
An editorial discusses a retrospective cohort study of intraoperative endoscopic pyloric balloon dilation (EPBD) to prevent delayed gastric conduit emptying after esophagectomy. The authors describe lower rates of early delayed emptying and hospital-acquired pneumonia, while noting that small-group and sequential observational design limit conclusions.
- Retrospective cohort findings favored intraoperative EPBD for early outcomes.
- Sample sizes and numerical effect estimates are not provided.
- Long-term effects on reflux and dumping syndrome remain unknown.
- Randomized trials PROPPER and WIDE are underway.
Delayed gastric conduit emptying (DGCE) is a common complication after esophagectomy and can contribute to aspiration, pneumonia, longer hospitalization, and delayed recovery. Pyloroplasty may reduce DGCE but has been associated with bile reflux and dumping syndrome. The editorial reviews a multicentre retrospective cohort study comparing early outcomes in patients who received intraoperative EPBD with those who did not; the source does not provide sample sizes or effect estimates.
The study reported significant reductions in early DGCE and hospital-acquired pneumonia, its primary endpoints, as well as in overall complications. Retained food at interval endoscopy was also less frequent after EPBD, although the impact on quality of life was unclear.
The editorial authors consider prophylactic EPBD a possible alternative to pyloroplasty or treatment only after symptoms develop, but emphasize that the sequential observational design cannot establish that EPBD caused the improvements. Long-term effects, including on bile reflux, dumping syndrome, and patient-reported quality of life, remain unknown. Randomized trials PROPPER and WIDE are underway to assess prophylactic EPBD; the editorial concludes that current evidence is promising but insufficient to establish the optimal approach.
In practice
For patients undergoing esophagectomy, prophylactic intraoperative EPBD is a promising approach to reduce early delayed gastric conduit emptying and pneumonia, based on a retrospective cohort summarized in this editorial. The source provides no sample sizes or effect estimates, and the sequential observational design cannot establish causality. It also does not establish whether EPBD affects longer-term bile reflux, dumping syndrome, or quality of life. The ongoing randomized PROPPER and WIDE trials are expected to provide more definitive evidence; the current findings do not establish a preferred strategy.
