ABSTRACT
Background and Aim: spondylolisthesis is a visible deformity in lumbosacral region with vertebral slip and fracture or other deformities of pars interarticularis. This study aims at investigating the characteristics of spondylolisthesis surgery in operated patients
Methods and Materials/Patients: this is a retrospective study which included all the patients who had undergone spondylolisthesis surgery by one same surgeon from 2006 to 2011. Demographic characteristics such as age, gender, and surgery information including type of spondylolisthesis, incision site, laminectomy site, foraminotomy site, fixation site of vertebra and site of vertebral disc evacuation were collected. The data were analyzed using SPSS [Version16]
Results: 52 of 63 enrolled patients were women [82.5%] and 11 men [17.5%] with mean age of 49.6 years. Based on frequency, spondylolisthesis types were 60 degenerative [95.2%], 2 post-surgical [3.2%] and 1 post-traumatic [1.6%], respectively. 58 patients had spondylolisthesis only in one vertebra and 5 patients in two vertebrae. The total number of slipped vertebrae was 68, in which slip was seen in L3, L4 or L5 vertebrae. In 42 patients, laminectomy was performed only in one vertebra, in 19 patients in two vertebrae, in 1 patient in three vertebrae and in 1 patient in five vertebrae. The total number of vertebrae with foraminotomy was 106. The highest frequency of foraminotomy was seen in L5, L4, and S1 vertebrae, respectively. Except in one case, the rest 62 patients underwent fixation surgery in two or three vertebrae
Conclusion: based on the results, the frequency of spondylolisthesis was approximately five times in women compared to men. The most common type was degenerative spondylolisthesis. Type of surgery was fixation with pedicle screw and fusion
ABSTRACT
Background and Aim: we described the presentation, management and subsequent treatment outcomes of children and adolescents diagnosed with a pituitary adenoma in a joint neuroendocrine setting followed up by a single service as well as assessing long-term outcomes in terms of endocrine status and neurology symptoms
Methods and Materials/Patients: a total of 21 participants with histologically verified pituitary adenoma between January 2011 and June 2014 were studied. Patients' data from clinical, radiological and pathological records were analyzed using SPSS [Version 16]
Results: all these children and adolescents with pituitary adenomas were managed with microscopic transsphenoidal surgery. The most common symptom was Cushing [47.6%, n=10]. The functional type [76.2%, n=16] was more than the non-functional. The post-operative control MRI of most of them was clear [90.5%, n=19]. The lab control of most of them was normal [76.2%, n=16]. Apoplexy was seen in 5 patients [33.8%]. Gross-total resection [GTR; 100% tumor removal as judged by early post-operative imaging] was achieved in 19 cases. Only one of these patients showed evidence of radiologic recurrence
Conclusion: in our study, all patients underwent microscopic transsphenoidal surgery due to limitation of endoscopic approach in pediatric and avoided wide anatomical deficit. Doing a comparative study between these two approaches will bring about promising results
