Data Sheet 1_New sights of spleen-preserving versus splenectomy in distal pancreatectomy f

A systematic review and meta-analysis of 4 retrospective studies involving 457 patients with pancreatic neuroendocrine tumors, comparing surgical outcomes between spleen-preserving and splenectomy procedures. The analysis, registered on PROSPERO, was conducted by Haonan Liu and published on figshare in 2026. It pools data on intraoperative blood loss, lymph nodes harvested, operative time, and postoperative complications.

Use Cases

• Compare perioperative outcomes like blood loss and operative time between SPDP and DPS based on the pooled analysis.
• Assess the feasibility of spleen-preserving surgery for small, well-differentiated G1/G2 tumors as suggested by the patient cohort.
• Investigate the relationship between surgical technique and postoperative complications such as major complications and pancreatic fistula.
• Validate or inform the design of future clinical studies on surgical approaches for pancreatic neuroendocrine tumors.

Strengths

• Analysis is based on a pooled cohort of 457 patients from 4 studies, providing a quantitative synthesis.
• Reports specific statistical measures including standardized mean differences, odds ratios, and 95% confidence intervals for key outcomes.
• The study protocol is formally registered with PROSPERO (CRD420251079167), indicating a structured methodology.

Limitations

• The dataset is a 31.6 KB DOCX file, which is a text document; the underlying raw patient-level data is not provided.
• All included studies are retrospective, which may introduce selection bias.
• Row count and column-level documentation for any underlying data are unknown.
