Prophylactic Pyloric Dilatation and its Impact on Early Delayed Gastric Conduit Emptying and Pneumonia Post-esophagectomy: A Multi-centre Cohort Study.

BACKGROUND Early delayed gastric conduit emptying (DGCE) and pneumonia are among the most common complications following oesophagectomy. These issues can be challenging to address during minimally invasive surgery with pyloroplasty or pyloromyotomy. This study evaluated the impact of prophylactic endoscopic pyloric bal...
