Popis: | This study aimed to investigate the long-term clinical outcomes after surgical decompression in cauda equina syndrome (CES) and see if any preoperative patient-related factors contributed to this outcome. A systematic literature search was conducted in the electronic databases of PubMed, Embase, Scopus, and Ovid. Data regarding outcome parameters from eligible studies were extracted. Meta-analysis was performed using a random-effect model. A total of 852 patients (492 males and 360 females), with a mean age of 44.6 ± 5.5 years from 22 studies diagnosed with cauda equina syndrome and undergoing surgical decompression, were included in the meta-analysis; however, not all studies reported every outcome. The mean follow-up period was 39.2 months, with a minimum follow-up of 12 months in all included studies. Meta-analysis showed that on long-term follow-up, 43.3% [29.1, 57.5] (n=708) of patients had persistent bladder dysfunction. Persistent bowel dysfunction was observed in 31.1% [14.7, 47.6] (n=439) cases, sensory deficit in 53.3% [37.1, 69.6] (n=519), motor weakness in 38.4% [22.4, 54.4] (n=490), and sexual dysfunction in 40.1% [28.0, 52.1] (n=411). Decompression within 48 hours of the onset of symptoms was associated with a favourable outcome in terms of bladder function with 24.6% [1.6, 50.9] (n=75) patients having persistent dysfunction, whereas 50.3% [10.3, 90.4] (n=185) of patients in studies with a mean time to decompression after 48 hours had persistent bladder dysfunction. Other factors such as speed of onset and sex of the patients were not found to significantly impact long-term bladder outcomes. The long-term outcomes of CES after decompression are enumerated. Decompression within 48 hours of the onset of symptoms appears to result in fewer patients with persistent bladder dysfunction. However, a randomized controlled trial is required to conclusively determine whether early decompression leads to better outcomes. |
