Smartphone-assisted endoscopic surgery via Kocher's point for intraventricular hemorrhage caused by thalamic hemorrhage: A comparison with external ventricular drainage.

The aim of the present study was to investigate the efficacy of endoscopic surgery via a Kocher point approach for intraventricular hemorrhage (IVH) caused by thalamic hemorrhage (TH), in comparison with external ventricular drainage (EVD). Between January 2016 and August 2017, a total of 40 patients with IVH caused by TH were enrolled. The patients were assigned to an EVD group and an endoscopic surgery group in a non-randomized manner. The pre-operative characteristics recorded included age, pre-operative Glasgow Coma Scale (GCS) score, hemorrhage volume, length of neuro-intensive care unit stay and Graeb score of IVH. Outcomes included the GCS score at 2 weeks after surgery, 30-day and 90-day mortality rates, modified Rankin scale at 6 months after ictus and ventriculo-peritoneal (VP) shunt rate. The baseline characteristics were not significantly different between the two groups. The VP shunt rate in the EVD group was significantly higher compared with that in the endoscopic surgery group (50.0 vs. 15.0%; P=0.02; odds ratio, 5.7). In conclusion, smartphone-assisted endoscopic surgery via Kocher's point is feasible and safe, and significantly reduces permanent shunt dependency for IVH caused by TH.
