Objective:
The aim of this study was to perform a systematic review and meta-analysis on the safety and effectiveness regarding outcomes of minimally invasive total pancreatectomy (MITP) versus open total pancreatectomy (OTP).
Background:
Total pancreatectomy is a complicated operation in abdominal surgery. The flexibility of minimally invasive surgery offers a new surgical approach to this technology. At present, there is little research on MITP, and its advantages over OTP remain uncertain.
Methods:
A systematic literature review and meta-analysis was conducted basing on comparative studies between MITP and OTP from January 1943 to November 2022. Intraoperative outcomes and postoperative outcomes were assessed. Pooled odds ratios (ORs) and mean differences with a 95% CI were calculated using fixed-effect or random-effect models under heterogeneity.
Results:
Seven studies with a total of 4275 patients were included. The major morbidity in the MITP group was significant lower (OR 0.50, 95% CI: 0.30-0.84, P=0.008, I²= 0%) than OTP group. At the same time, comparing with OTP, the MITP group had lower estimated blood loss (MD -362.50, 95% CI -641.34 to -83.66, P=0.01, I²=96%) and lower intraoperative transfusion rate (OR 0.36, 95% CI 0.16-0.84, P=0.02, I²=0%). There were no significant differences between the MITP and OTP groups for other outcomes.
Conclusions:
The results suggested that MITP was associated with lower major morbidity, estimated blood loss, and intraoperative transfusion rate comparing with OTP. However, the further evidence with a better design is required.
Insights
Minimally invasive total pancreatectomy (MITP) shows reduced major morbidity, blood loss, and transfusion rates compared to open total pancreatectomy (OTP). Further high-quality studies are needed to confirm these findings for this complex abdominal surgery.
Area of Science:
- Surgical Oncology
- Gastrointestinal Surgery
- Minimally Invasive Procedures
Background:
- Total pancreatectomy is a complex abdominal surgery.
- Minimally invasive surgery offers a novel approach.
- Limited research exists on minimally invasive total pancreatectomy (MITP) versus open total pancreatectomy (OTP).
Conclusions:
- MITP appears to be a safer alternative to OTP, with lower major morbidity, blood loss, and transfusion requirements.
- Further high-quality research with robust study designs is warranted to solidify these conclusions.
