Preoperative Endoscopic Ultrasound Elastography for Prediction of Intraoperative Pancreatic Texture and Postoperative Pancreatic Fistula After Pancreaticoduodenectomy: A Prospective Study
In Brief
An observational study evaluating Preoperative Endoscopic Ultrasound Elastography (EUS Elastography) for Pancreatic Neoplasms and Pancreatic Fistula. Currently recruiting, targeting 100 participants across 1 site.
Detailed Summary
This prospective study evaluates whether preoperative endoscopic ultrasound elastography (EUS-E) can predict pancreatic texture during surgery and risk of postoperative pancreatic fistula (POPF) in 100 patients undergoing pancreaticoduodenectomy. EUS-E measures pancreatic stiffness preoperatively. Intraoperative texture ("soft" or "hard") is assessed by surgeons blinded to EUS-E results. POPF is graded using ISGPF criteria. Predictive accuracy of EUS-E will be analyzed statistically.
Study Details
Timeline
Interventions
All enrolled patients will undergo a preoperative EUS-E examination within one weeks prior to pancreaticoduodenectomy. The EUS-E will be performed by experienced endosonographers using a radial or linear array echoendoscope connected to a compatible ultrasound processor. Both qualitative (color mapping) and quantitative (strain ratio, strain histogram) data will be obtained. Multiple measurements of the strain ratio will be taken from a region of interest within the pancreatic parenchyma adjacent to the lesion. The mean strain ratio will be recorded for analysis. Standard EUS imaging will also be recorded. Standard pancreaticoduodenectomy will be performed . Intraoperative pancreatic texture will be subjectively assessed by the surgeon and recorded. Postoperative monitoring for pancreatic fistula will follow established clinical guidelines.
