Pyloric balloon dilation during minimally invasive Ivor‑Lewis esophagectomy to reduce delayed gastric conduit emptying
Official title: Patients With Esophageal Carcinoma Undergoing Minimally Invasive Ivor Lewis Esophagectomy With or Without Intraoperative Endoscopic Pylorus Balloon Dilation: A Randomized Controlled Trial Investigating the Benefits of Intraoperative Endoscopic Pylorus Dilation
Run by University Hospital, Basel, Switzerland · NCT07355374 · Data updated 2026-11-12
This trial will see if a brief endoscopic balloon dilation of the pylorus during minimally invasive Ivor‑Lewis esophagectomy reduces early delayed gastric conduit emptying in adults having surgery for esophageal cancer.

Is this trial a fit for you?
✓Likely a good fit
Adults over 18 with histologically confirmed esophageal cancer scheduled for curative minimally invasive Ivor‑Lewis esophagectomy who can provide informed consent.
✕Probably not a fit
Patients with prior esophageal or gastric resections, those undergoing non‑curative surgery, patients with ASA V, or those unable to consent are excluded and unlikely to benefit from this intervention.

What this trial studies
The WIDE Trial is a prospective, single‑center, double‑blinded, randomized controlled trial at Clarunis University Digestive Health Care Center in Basel. Adults scheduled for curative minimally invasive Ivor‑Lewis esophagectomy are randomized to receive intraoperative endoscopic pyloric balloon dilation performed by experienced gastroenterologists or the control procedure. The primary outcome is the incidence of early postoperative delayed gastric conduit emptying (DGCE), with secondary assessments of recovery metrics and quality of life. Follow‑up at the center captures postoperative complications and functional outcomes.
Why it matters
Potential benefit: If successful, the procedure could lower the rate of early DGCE, speed recovery after surgery, and reduce related complications and healthcare costs.
How similar studies have gone: Retrospective and nonrandomized reports have suggested that mechanical pyloric stretching may reduce DGCE, but randomized evidence in the minimally invasive Ivor‑Lewis setting is currently lacking.
