Abstract
BACKGROUNDS
Delayed symptomatic hyponatremia (DSH) is one of the common complications following endoscopic endonasal surgery (EES). Currently, published studies have predominantly focused on delayed postoperative hyponatremia, while there is relatively limited research on DSH.
METHODS
We analyzed 175 consecutive cases from a single center between 2019 and 2023, involving patients who underwent endoscopic endonasal surgery (EES) for pituitary adenoma or Rathke's cleft cyst (RCC), all histopathologically confirmed. We collected preoperative, intraoperative, and postoperative data, and performed statistical analysis to determine the incidence of postoperative diabetes insipidus (DI) and identify significant predictive factors. Based on these factors, we developed a simplified scoring system.
RESULTS
There were 29 cases (16.6%) of DSH occurrence. In the binary logistic regression analysis, Knosp grade ≥3 (OR, 4.19; 95% CI, 1.26-13.92; P=0.019), intraoperative cerebrospinal fluid leaks (OR, 3.93; 95% CI, 1.49-10.34; P=0.006), serum sodium on the second day after surgery (OR, 0.88; 95% CI, 0.78-1.00; P=0.049), and postoperative diabetes insipidus (OR, 2.88; 95% CI, 1.10-7.53; P=0.031) were factors with independent predictive value for DSH. The scoring system achieved a maximum area under the ROC curve (AUC) of 0.789 (95% CI, 0.697-0.881), with a cutoff value of 1, sensitivity of 86.2%, and specificity of 59.6%.
CONCLUSION
The incidence rate of DSH after EES in patients was 16.8%. Knosp grade ≥3, intraoperative cerebrospinal fluid leaks, serum sodium concentration on the second day after surgery, and postoperative diabetes insipidus were associated with the occurrence of DSH.
期刊介绍:
World Neurosurgery has an open access mirror journal World Neurosurgery: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
The journal''s mission is to:
-To provide a first-class international forum and a 2-way conduit for dialogue that is relevant to neurosurgeons and providers who care for neurosurgery patients. The categories of the exchanged information include clinical and basic science, as well as global information that provide social, political, educational, economic, cultural or societal insights and knowledge that are of significance and relevance to worldwide neurosurgery patient care.
-To act as a primary intellectual catalyst for the stimulation of creativity, the creation of new knowledge, and the enhancement of quality neurosurgical care worldwide.
-To provide a forum for communication that enriches the lives of all neurosurgeons and their colleagues; and, in so doing, enriches the lives of their patients.
Topics to be addressed in World Neurosurgery include: EDUCATION, ECONOMICS, RESEARCH, POLITICS, HISTORY, CULTURE, CLINICAL SCIENCE, LABORATORY SCIENCE, TECHNOLOGY, OPERATIVE TECHNIQUES, CLINICAL IMAGES, VIDEOS
