BACKGROUND: The rise of minimally invasive inguinal hernia repair has seen both the laparoscopic and robotic approaches increase in popularity in recent years. Despite this, seroma formation remains a common complication, and the aim of this study is to evaluate the current evidence on seroma-prevention strategies in minimally invasive inguinal hernia repair. MATERIALS AND METHODS: Four databases (PubMed, Scopus, Embase, and Cochrane Library) were searched from inception to November 15, 2021. All studies describing the use of intraoperative adjuncts to reduce postoperative seroma formation in patients undergoing laparoscopic or robotic inguinal and inguinoscrotal hernia repair were included. Meta-analyses were performed using Review Manager (Version 5.4). RESULTS: 2,382 articles were identified in the initial database search, and 40 articles were included in the final analysis. In this analysis, there was a significantly lower incidence of seroma formation in the drain group when compared to the no-drain group (P < 0.00001). Other strategies aimed at reducing the dead space involving the transversalis fascia (TF) and hernia sac such as TF inversion with tacking, Endoloop closure of TF, barbed suture closure of TF, distal sac fixation, and complete dissection of the sac have shown promising results as well. CONCLUSIONS: While there is currently insufficient evidence to recommend the routine use of any one of the interventions analyzed, the use of drains, the management of the TF, and the hernia sac have showed potential in reducing seroma formation. |
