Abstract
BackgroundEndoscopic transsphenoidal surgery has gradually come to be regarded as a preferred option in the treatment of pituitary adenomas because of its advantages of improved visualization and its minimal invasiveness. The aim of this study was to compare and evaluate the outcomes and complications of endoscopic and microscopic transsphenoidal surgery in the treatment of pituitary adenomas.MethodsWe performed a systematic literature search of MEDLINE, EMBASE, the Cochrane Library and the Web of Science between January 1992 and May 2013. Studies with consecutive patients that explicitly and fully compared endoscopic and microscopic approaches in the treatment of pituitary adenomas were included.ResultsA total of 15 studies (n = 1,014 patients) met the inclusion criteria among 487 studies that involved endoscopic surgery and 527 studies that dealt with microscopic surgery. The rate of gross tumor removal was higher in the endoscopic group than in the microscopic group. The post-operative rates of septal perforation were less frequent in patients who underwent endoscopic surgery. There was no significant difference between the two techniques in the incidence rates of meningitis, diabetes insipidus, cerebrospinal fluid leak, epistaxis or hypopituitarism. The post-operative hospital stay was significantly shorter for the endoscopic surgery group compared with the microscopic surgery group (P < 0.05). There was no significant difference in the length of the operation (P > 0.05).ConclusionsThe present study indicates that the endoscopic transsphenoidal approach is safer and more effective than microscopic surgery in the treatment of pituitary adenomas.

Four additional records which meet the inclusion criteria were obtained through a manual search
A sensitivity analysis was performed by removing two studies [18,20], and the outcome of the analysis revealed a significant difference between the endoscopic group and the microscopic group, which was consistent with previous results (OR = 1.93, 95% confidence interval (CI) 1.38 to 2.70) (Figure 3.1)
Summary
Endoscopic transsphenoidal surgery has gradually come to be regarded as a preferred option in the treatment of pituitary adenomas because of its advantages of improved visualization and its minimal invasiveness. The aim of this study was to compare and evaluate the outcomes and complications of endoscopic and microscopic transsphenoidal surgery in the treatment of pituitary adenomas. Schloffer et al [2] were the first to report the transsphenoidal approach in a sella tumor in 1907. It was Cushing et al [3] who abandoned external incisions and popularized the sublabial transseptal transsphenoidal technique. In the 1960s, Hardy [4] perfected Cushing’s approach with the introduction of the operative microscope.
