Current status of diagnosis and management of postoperative complications after endoscopic endonasal transsphenoidal approach to pituitary adenoma removal / 中国综合临床

Pituitary adenoma is one of the most common intracranial tumors, and most of them can be well removed by endoscopic transsphenoidal surgery. Pituitary adenoma is located in the sella, which can compress the pituitary and optic nerve, invade the sphenoid sinus and cavernous sinus, invade and grow in all directions, and affect the endocrine function at the same time. Endoscopic transsphenoidal pituitary adenoma resection (EETS) has the advantages of minimally invasive, close observation, panoramic view, high tumor resection rate and high preservation rate of normal pituitary function, but it can cause pituitary endocrine disorder, diabetes insipidus, electrolyte disorder, cerebrospinal fluid leakage, intracranial infection, cerebral nerve paralysis, tumor cavity, intracranial hemorrhage, rhinitis and other related complications. It affects the prognosis and quality of life of patients. The postoperative complications of EETS are not only related to the pathophysiological characteristics of pituitary adenoma, but also closely related to the depth of understanding of pathology and anatomy of pituitary adenoma, surgical skills, proficiency and clinical experience. Familiarity with endoscopic anatomy and fine surgical techniques, rich surgical experience, strict preoperative endocrine function evaluation, hormone replacement therapy, etc. can reduce the incidence of postoperative complications of EETS.

Endoscopic endonasal transsphenoidal surgery of symptomatic Rathke′s cleft cyst in sellar region / 重庆医学

Objective To explore the clinical characteristic of Rathke′s cleft cyst and assess the effect of endoscopic en-donasal transsphenoidal surgery .Methods A retrospective research was performed on 9 patients who underwent endoscopic en-donasal transsphenoidal surgery .Neural endoscopic surgery by single nostril transsphenoidal approach ,partial resection of the cyst wall with drainage of the intracystic contents was performed in all patients .Results Symptoms in all patients were resolved or alle-viated .No CSF rhinorrhea ,permanent diabetes insipidus and hypopituitarism happened .All patients were followed up for 4 to 12 months and no recurrence was found .Conclusion Endoscopic endonasal transsphenoidal surgery is a effective method for symptom-atic Rathke′s cleft cysts .
