Valveless and conventional insufflation on pneumoperitoneum-related complications in robotic partial nephrectomy: a systematic review and meta-analysis of prospective studies.

Introduction: The use of pneumoperitoneum is an essential step for performing laparoscopic and robotic surgery. Pneumoperitoneum insufflation can cause complications such as pneumothorax, subcutaneous emphysema, and pneumomediastinum. The purpose of this meta-analysis is to compare the safety of using the conventional insufflation system versus a Valveless insufflation system as devices for manufacturing pneumoperitoneum in robotic-assisted nephrectomy.
Methods: A comprehensive literature search was conducted on PUBMED, EMBASE, SCOPUS, and Cochrane, from inception until January 2024. Randomized and nonrandomized prospective studies were included in the meta-analysis, performed by the R+ Rstudio.
Results: Three publications encompassing 478 patients were included. We observed no difference in SCE (OR 0.60, CI 95% 0.27;1.34, p = 0.134, I ²  = 0), PNM (OR 0.82, CI 95% 0.24;2.78, p = 0.558, I ²  = 0), When comparing groups conventional insufflation system (CIS) versus AirSealTM insufflation system (AIS) with pneumoperitoneum pressure of 15 mmHg or 12 mmHg.
Conclusion: The presented data showed no difference between the AIS when compared with CIS in Pneumoperitoneum insufflation-related complications.
