The role of endoscope-assisted septectomy and membranectomy for complex chronic subdural hematomas: safety, efficacy, technical feasibility. Patient series.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBurr hole craniostomy and conventional craniotomy are respectively associated with high recurrence rates and morbidities in the evacuation of septated chronic subdural hematomas (CSDHs). The safety and efficacy of endoscope-assisted septectomy and membranectomy (ESM) via a mini-craniotomy are investigated in this subset of patients. OBSERVATIONS: Thirteen patients with a mean age of 75 ± 11.5 years and a median modified Rankin Scale (mRS) score of 4 were included. Surgeries had a mean craniotomy size of 3.6 ± 0.5 cm and a median duration of 142 minutes. Initial postoperative CT imaging confirmed complete hematoma evacuation. Six patients (46.2%) underwent perioperative middle meningeal artery embolization (MMAE) without complications. The mean length of hospital stay (LOS) was 8 ± 3.9 days. Lower preoperative Glasgow Coma Scale (GCS) scores (p = 0.049) and larger midline shifts (p = 0.024) were significantly associated with LOS > 5 days. Median mRS scores significantly improved at discharge (p < 0.015) and at the last follow-up (p < 0.009), yielding a low-tier mRS score (≤ 2) in 53.8% of patients at discharge and 92.3% favorable last follow-up outcomes. A higher admission GCS score was associated with a low-tier at-discharge mRS score (p = 0.048). Complete brain reexpansion occurred within a mean time of 6.2 ± 4.1 months, with no significant correlation with radiological and operative features or MMAE history. During a mean follow-up of 17.4 ± 13.4 months, no recurrences were observed. LESSONS: ESM is an effective, minimally invasive alternative for treating septated, multiloculated CSDH, offering minimal recurrences. Although operative times are longer, reduced reoperation rates and improved safety justify this strategy for complex hematomas. https://thejns.org/doi/10.3171/CASE25446.
