The reported incidence of postoperative ileus (POI) after spine surgery depends on the surgical approach and definition used. It is therefore possible that the overall incidence is substantially higher than previously thought. POI has consequences for both the patient and hospital resources, and can significantly increase health care costs. ⋯ Despite use of early interventions, the median LOS remains significantly longer in patients who develop POI after complex spine surgery. Knowledge of the associated predictive risk factors could potentially assist with the development of rigorous, evidence-based preventative strategies.

Ehlers-Danlos syndrome can be associated with cerebrospinal fluid (CSF) disturbances including recurrent CSF leak and Chiari I malformations. Persistent pseudomeningoceles are known to be associated with raised intracranial pressure. We present an unusual case of a compressive epidural CSF collection occurring after a computed tomography-guided L5 nerve root block and describe an effective management strategy.

To analyze the preservation of hypothalamic function using the endoscopic endonasal approach (EEA) in a single-center clinical series of patients with hypothalamus-invaded craniopharyngioma (CP) and compare this series with reported cases by the open transcranial approach (TCA). ⋯ EEA can achieve greater gross total resection than TCA when performed by an experienced surgeon. Combined with the reduced postoperative hypothalamic damage in our patients with only hypothalamus-invaded CP, especially the shortened time horizons of hypothalamic obesity development and reduced percentage of patients with obesity, the EEA technique should be a preferred alternative over TCA.

To determine postoperative long-term changes of hippocampal volume (HV) correlating with cognitive functions in patients who underwent surgery for hippocampal sclerosis with postoperative freedom from seizures. ⋯ In seizure-free patients after hippocampal sclerosis resection , unresected contralateral HV significantly declined with older age at surgery. Visual memory was preserved regardless of side and volume loss. Despite significantly reduced HVs, verbal memory was preserved with the unresected contralateral dominant hippocampus. Earlier surgical intervention may have lower potential risk for memory decline secondary to postoperative HV loss.

To search for texture features of routine magnetic resonance imaging to predict tumor volume reduction and transient versus permanent tumor progression of vestibular schwannomas treated by Gamma Knife stereotactic radiosurgery. ⋯ Texture feature analysis helps to predict permanent versus transient enlargement and final volume reduction of schwannomas after SRS. Thus, alternative treatment strategies might be considered, mainly in large tumors, where further clinical deterioration cannot be excluded. To confirm these results, a prospective study including more cases and a longer follow-up period is necessary.
