Summary
This review analyzes 34 randomized controlled trials (RCTs) on pancreaticoduodenectomy (PD) over the last decade. While RCT quality varied, findings offer high-grade evidence to improve surgical outcomes and patient quality of life.
Area of Science:
- Gastroenterology and Hepatology
- Surgical Oncology
- Clinical Trials Methodology
Background:
- Pancreaticoduodenectomy (PD) is a complex surgical procedure.
- Evaluating the evidence base from randomized controlled trials (RCTs) is crucial for advancing PD techniques.
- Recent advancements in PD necessitate a review of high-quality research.
Purpose of the Study:
- To systematically analyze and summarize prospective randomized controlled trials (RCTs) on pancreaticoduodenectomy (PD) published in the last decade.
- To assess the geographical distribution, study themes, sample sizes, and quality of these RCTs.
- To provide insights into the current state of evidence for PD.
Main Methods:
- A comprehensive MEDLINE search identified prospective RCTs on PD from the past 10 years.
- Eligible RCTs were analyzed based on publication year, region, focus, participant numbers, and multicenter status.
- The methodological quality of each RCT was critically evaluated.
Main Results:
- Thirty-four RCTs met the inclusion criteria, with 1-6 published annually.
- Europe led in trial conduct (15), followed by North America (10) and Asia (9).
- Common research areas included postoperative complications (pancreatic fistula, delayed gastric emptying), anastomotic techniques, and comparisons of PD variations (standard vs. extended lymphadenectomy, pylorus-preserving vs. standard).
- The average sample size was 117, with 10 trials having fewer than 50 participants.
- Multicenter studies constituted 21% of all RCTs, doubling in the last five years.
- Sample size calculation was reported in only 14 RCTs, and intention-to-treat analysis in 26.
Conclusions:
- The review encompasses 34 global RCTs on pancreaticoduodenectomy (PD).
- Despite limitations in methodological quality, the high-grade evidence generated by these RCTs is vital for clinical application.
- Implementing findings from these studies can enhance surgical quality and improve patient outcomes and quality of life.
