BACKGROUND: Minimally invasive spine (MIS) surgery utilizing tubular retractors has become an increasingly popular approach for decompression in the lumbar spine. However, a better understanding of appropriate indications, efficacious surgical techniques, limitations, and complication management is required to effectively teach the procedure and to facilitate the learning curve. OBJECTIVE: To describe our experience and recommendations regarding tubular surgery for lumbar disc herniations, foraminal compression with unilateral radiculopathy, lumbar spinal stenosis, synovial cysts, and dural repair...

Y Y Zhang, L X Xie
Endothelial keratoplasty (EK) has gradually replaced penetrating keratoplasty (PKP) and has become the main method for the treatment of endothelial dysfunction in developed countries in recent years. EK is safe and effective and can achieve good postoperative vision. The surgical techniques and postoperative effects have been improved continuously along with the development of microsurgical technology and surgical instruments. The EK surgeries mainly include Descemet stripping endothelial keratoplasty (DSEK), Descemet stripping automated endothelial keratoplasty (DSAEK), Descemet membrane endothelial keratoplasty (DMEK) and ultra-thin Descemet stripping automated endothelial keratoplasty (UT-DSAEK), which have different characteristics and advantages compared with PKP...

Colloid cysts are benign lesions, found in the anterior part of the roof of the third ventricle. A PubMED search of literature was performed to identify the evidence on different treatment options and surgical approaches for removal of colloid cysts. Evidence on endoscopic versus microsurgical resection of colloid cysts showed that microsurgical approach had significantly higher rates of gross total resection, lower recurrence rate and lower re-operation rate. No significant difference with respect to the mortality rate or the need for a shunt was found between the two groups...

BACKGROUND: The pterional approach (PA), together with its variants, is still one of the most common methods used by surgeons to reach the anterior and middle cranial base. A highly important technical detail during a PA is the preservation of the frontotemporal branch of the facial nerve, which can be achieved through an interfascial dissection. OBJECTIVE: To describe the anatomy of the interfascial vein (IFV), highlighting its recognition as a significant anatomic reference to perform an interfascial dissection (IFD)...

Insight into processes leading to rupture of intracranial aneurysms (IAs) may identify biomarkers for rupture or lead to management strategies reducing the risk of rupture. We characterized and quantified (ultra)structural differences between unruptured and ruptured aneurysmal walls. Six unruptured and 6 ruptured IA fundi were resected after microsurgical clipping and analyzed by correlative light microscopy for quantitative analysis (proportion of the vessel wall area) and transmission electron microscopy for qualitative ultrastructural analysis...

Post operative complications after pituitary tumour surgery vary according to procedure. There are several surgical procedures being done such as transcranial, transsphenoidal microsurgical and transsphenoidal endoscopic approaches. One of the commonest complications is diabetes insipidus (DI). Our main objective was to find out the incidence of diabetes insipidus in post operative period among patients undergoing surgical intervention for pituitary tumour in our institute. The presence of diabetes insipidus in the postoperative period was established by measuring serum Na+ concentration, hourly urine output and urinary specific gravity to find out the incidence of diabetes insipidus in postoperative period in relation to age, gender, tumour diameter, function of tumour (i...

INTRODUCTION: Pyoderma gangrenosum (PG) is a rare type of autoimmune disease that results in progressive ulcers with or without previous trauma. However, PG is not well understood to date, and its treatment therefore remains a challenge. Because of the disease's systemic characteristic and the unpredictability of the clinical course, no gold standard treatment is available, especially concerning the surgical procedures to treat pyodermic lesions. Often, PG is not recognized during routine clinical practice, and standard ulcer treatment (conservative wound care, debridement, skin grafting, and local flap coverage) is initiated; this induces an autoinflammatory response, resulting in disastrous ulcers, thereby making free flap coverage necessary...

Vasectomy is the method of contraception chosen by more than 500,000 American men annually, and by upwards of 8% of married couples worldwide. However, following the procedure, nearly 20% of men express the desire for children in the future, and approximately 2-6% of American men will ultimately undergo vasectomy reversal (VR). VR is a complex microsurgical procedure. Intraoperative decision-making, surgical technique, and postoperative management are each critical step in achieving high success rates. The aim of this article is to provide a detailed description of the operative and perioperative procedures employed by surgeons performing VRs...

Robert M Coward, Jesse N Mills
A variety of surgical options exists for sperm retrieval in the setting of obstructive azoospermia (OA). With appropriate preparation, the majority of these techniques can safely be performed in the office with local anesthesia and with or without monitored anesthesia care (MAC). The available techniques include percutaneous options such as percutaneous epididymal sperm aspiration (PESA) and testicular sperm aspiration (TESA), as well as open techniques that include testicular sperm extraction (TESE) and microsurgical epididymal sperm aspiration (MESA)...
