Evaluating the Heidelberg Triangle dissection in pancreatic surgeries

Application of "Heidelberg Triangle" Dissection in Pancreatoduodenectomy and Distal Pancreatectomy

Fudan University · NCT05703581

This study is testing a new surgical technique called the 'Heidelberg Triangle' to see if it helps people with pancreatic cancer live longer and have fewer recurrences after surgery.

What this trial studies

This study aims to assess the safety and effectiveness of the 'Heidelberg Triangle' dissection technique when combined with pancreatoduodenectomy or distal pancreatectomy for patients with pancreatic cancer and periampullary carcinoma. It involves a retrospective analysis of patients who underwent these surgeries between September 2016 and December 2022, categorizing them into TRIANGLE and non-TRIANGLE groups based on the surgical approach used. The study will utilize 3D reconstruction from preoperative enhanced CT scans to analyze the impact of this dissection method on recurrence and survival rates.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with resectable or borderline resectable pancreatic malignant tumors or periampullary carcinoma who can tolerate surgery.

Not a fit: Patients with other systemic malignancies or serious uncontrolled diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve surgical outcomes and prognosis for patients with pancreatic cancer.

How similar studies have performed: While recent studies suggest potential benefits of the TRIANGLE operation, data on its effectiveness remains limited, indicating this approach may be novel.
