Filter by:The goal of this observational study is to evaluate the effectiveness and impact of Enhanced Recovery After Surgery (ERAS) on patients with pituitary gland tumors.
This is a prospective, single-blinded, multicenter study evaluating the benefit of sinonasal irrigations following endoscopic pituitary surgery. The goal of this study is to create practice changing guidelines with objective data highlighting the importance of irrigations on postoperative outcomes for pituitary surgery.
The primary objective of this study is to evaluate the diagnostic performance of the CONVIVO confocal endomicroscope in discriminating between normal and abnormal tissue in vivo during brain tumor surgery. The interpretation of intraoperative images obtained in situ will be tested against conventional histologic evaluation of targeted biopsies from imaged tissue. The study team hypothesize that there will be a high degree of correlation between images obtained with the CONVIVO system and conventional histologic interpretation.
To conduct a retrospective multicenter cohort study to define benchmark values for best achievable outcomes following transsphenoidal resection of pituitary adenomas.
This is a prospective longitudinal study to access postoperative 2-year quality of life in patients who undergo endonasal endoscopic approach surgeries of the skull base.
The aim of this study is to determine the impact of endoscopic transsphenoidal pituitary surgery on nasal function using a numerical simulation and to compare the difference between two kinds of transsphenoidal approachese(single nostril approach and bilateral nostril approach)．
The study aims to update current knowledge about the epidemiology of pituitary tumours (PiT), based on the wide body of scientific literature on new familial and/or syndromic forms. Although inherited predisposition is increasingly recognized, its clinical relevance in unselected series of PiT patients has not been specifically addressed. In addition, it is likely that further recognition of peculiar associations between PiT and other endocrine and/or non-endocrine neoplasia will further increase the spectrum of syndromic forms. Since the identification of inherited forms of PiT may have significant clinical implications in terms of patients management and familial screening, we aim to collect any relevant information in order to estimate their prevalence in a large unselected series of PiT patients and provide new clues for a modern clinical approach to these patients.
Transsphenoidal pituitary tumor resection is currently recognized as an effective and safe surgical method,nowadays it is widely used in clinical practice . However ,Because of the endoscopic damage to the nasal mucosa during surgery and the old blood clots in the nasal cavity , after surgery the patient had nasal symptoms such as nasal congestion and nasal flow for a long time, which disturbed the patient's rest and sleep, affect their quality of life, some patients can develop to chronic sinus inflammation that is sphenoid sinusitis. Nasal irrigation is now widely used in the treatment of sinusitis and sphenoid sinusitis with good result. In this study, nasal irrigation was applied in the nursing process of patients after transsphenoidal pituitary tumor resection, and we want to establish the nursing management process of nasal irrigation after transsphenoidal pituitary tumor resection and use the visual analogue scale (VAS) to evaluate the nasal symptoms of patients after postoperative nasal irrigation. Use The Chinese version of the commonly used nasosinusitis scale (SNOT -20) to evaluate postoperative quality of life of patients from the four dimensions of rhino-related symptoms, vitality, social function and emotional function, and to evaluate the incidence of sphenoid sinusitis by combining imaging examination. It is expected to improve the comfort of postoperative nasal symptoms and postoperative quality of life, prevent and reduce the incidence of postoperative sphenoid sinusitis, and improve the satisfaction of patients.
Pituitary tumours have an estimated prevalence of 20% in the general population and the number of clinically relevant pituitary adenomas is increasing with time. When symptomatic, the standard of care required for pituitary adenomas is resection through an endoscopic transsphenoidal approach. There is however significant olfactory dysfunction following endoscopic transsphenoidal pituitary surgery with approximately 23% of patients reporting some degree of worsening in their sense of smell in the postoperative period. Pedicled nasoseptal flaps are used to repair skull base defects following resection of skull base tumours. The superior incision is placed in close proximity to olfactory mucosa. Currently, these flaps are raised either with the use of electrocautery or scalpel. The use of electrocautery in surgery has provided surgeons with greater hemostasis when compared to a scalpel. This is of utmost importance in many regions of the head & neck where highly vascularized tissue results in difficulties achieving adequate hemostasis and therefore limiting view of the surgical field. However, the use of electrocautery increases thermal damage to surrounding tissue and impairs wound healing when compared to a scalpel. Although the transmission of thermal energy via electrocautery to adjacent mucosa containing olfactory epithelium may theoretically contribute to olfactory disturbances, no prospective randomized controlled trials have yet examined the impact of these two different techniques on postoperative olfactory function. The purpose of this research study is to determine the effects, if any, of electrocautery versus scalpel on olfaction in raising the nasoseptal flap for repairing skull base defects following transphenoidal surgery.
As postoperative cognitive dysfunction rates are high especially in elder patients, cognitive dysfunction is not diagnosed and treated effectively. This statement is associated with prolonged hospital stays by increasing morbidity. We wanted to see the incidency of postoperative cognitive dysfunction in patients undergoing elective pituitary tumor removal surgery.
