Endoscopic surgery versus craniotomy in the treatment of spontaneous intracerebral hematoma: a systematic review and meta-analysis

Background: Spontaneous intracerebral hemorrhage (SICH) has high morbidity and mortality, with no clear standard of treatment available. Compared with the craniotomy approach, neuroendoscopy is a relatively minimally invasive treatment method, and may be an efficient alternative. Therefore, this meta-analysis aimed to assess the clinical efficacy of neuroendoscopy and craniotomy in SICH patients.Methods: The electronic databases Web of Science, PubMed, EmBase, MEDLINE, and the Cochrane Library were systematically searched. According to the PRISMA template, we finally selected and analyzed 14 eligible studies that evaluated neuroendoscopy versus craniotomy. Primary outcomes included operation time, intraoperative blood loss volume, evacuation rate, residual hematoma, complications, hospital stay duration, clinical outcomes, and other parameters.Results: A total of 4 randomized controlled trials (RCTs) and 10 retrospective studies (non-RCTs) involving 1652 patients were included in the final analysis. In the neuroendoscopy (NE) group, operation time (p < 0.00001), intraoperative blood loss volume (p < 0.0001), hematoma evacuation rate (p = 0.0002), complications (p < 0.00001), hospitalization days (p = 0.004), and mortality (p < 0.0001) were significantly different from those of the craniotomy (C) group, with a higher rate of good recovery compared with the craniotomy group (P < 0.00001).Conclusions: These findings suggest that patients with SICH and physicians may benefit more from neuroendoscopic surgery than craniotomy.
