[Study on the causes, prevention and treatment of complications after transsphenoidal pituitary tumor resection under...

Objective: To analyze the causes of complications after endoscopic transsphenoidal pituitary adenoma resection and summarize the corresponding prevention and treatment measures. Methods: The pathological data of 120 patients with pituitary adenoma in hospital were analyzed retrospectively. All patients were treated surgically, five kinds of common complications were collected, the risk factors of complications were statistically analyzed, the causes of postoperative complications were determined, and then the specific prevention and treatment strategies were summarized. Results: Long operation time (P<0.05), hypopituitarism before operation (P<0.01) and large tumor (P<0.01) were the main inducing factors of CSF rhinorrhea after operation; long operation time (OR=1.394, P<0.01), lumbar cistern puncture (OR=1.531, P<0.01) and CSF rhinorrhea after operation (OR=3.861, P<0.01) were the independent risk factors of infection; Age, large tumor and preoperative hypophysis are the main factors of postoperative hypophysis; Postoperative hypophysis and intraoperative cerebrospinal fluid rhinorrhea are the main factors of postoperative diabetes insipidus; Postoperative hypophysis and giant adenoma are the main factors of postoperative hyponatremia. Conclusion: Endoscopic transnasal transsphenoidal resection of pituitary adenoma is the most minimally invasive method at present. There are still risk factors for postoperative complications. Targeted prevention of risk factors for complications and corresponding interventions can effectively reduce the incidence of postoperative complications of pituitary adenoma.
