Safety and effectiveness of minimally invasive central pancreatectomy versus open central pancreatectomy: a systematic review and meta-analysis.

Abstract

Central pancreatectomy is a surgical procedure for benign and low-grade malignant tumors which located in the neck and proximal body of the pancreas that facilitates the preservation of pancreatic endocrine and exocrine functions but has a high morbidity rate, especially postoperative pancreatic fistula (POPF). The aim of this systematic review and meta-analysis was to evaluate the safety and effectiveness between minimally invasive central pancreatectomy (MICP) and open central pancreatectomy (OCP) basing on perioperative outcomes. An extensive literature search to compare MICP and OCP was conducted from October 2003 to October 2023 on PubMed, Medline, Embase, Web of Science, and the Cochrane Library. Fixed-effect models or random effects were selected based on heterogeneity, and pooled odds ratios (ORs) or mean differences (MDs) with 95% confidence intervals (CIs) were calculated. A total of 10 studies with a total of 510 patients were included. There was no significant difference in POPF between MICP and OCP (OR = 0.95; 95% CI [0.64, 1.43];P = 0.82), whereas intraoperative blood loss (MD = -125.13; 95% CI [-194.77, -55.49]; P < 0.001) and length of hospital stay (MD = -2.86; 95% CI [-5.00, -0.72]; P = 0.009) were in favor of MICP compared to OCP, and there was a strong trend toward a lower intraoperative transfusion rate in MICP than in OCP (MD = 0.34; 95% CI [0.11, 1.00]; P = 0.05). There was no significant difference in other outcomes between the two groups. MICP was as safe and effective as OCP and had less intraoperative blood loss and a shorter length of hospital stay. However, further studies are needed to confirm the results.
