backgrounds and objectives: today we are witnessed a growing number of minimally invasive surgical techniques for different diseases. laparoscopic colon surgery as a minimally invasive surgery is currently growing in treatment of malignancies after proving his place in the treatment of benign diseases. we compare in this study results of laparoscopic colorectal surgery with open surgery. method...

BACKGROUND Thoracic disc surgeries make up only a small number of all spine surgeries performed, but they can have a considerable number of postoperative complications. Numerous approaches have been developed and studied in an attempt to reduce the morbidity associated with the procedure; however, we still encounter cases that develop serious and unexpected outcomes. CASE PRESENTATION This ca...

OBJECT Recombinant human bone morphogenetic protein-2 (rhBMP-2) is being increasingly used for spinal fusion. There are few data regarding its clinical safety, effectiveness, and clinical outcome when applied on an absorbable collagen sponge (ACS) in conjunction with allograft for transforaminal lumbar interbody fusion (TLIF). METHODS Seventy-four consecutive patients undergoing TLIF for dege...

Degenerated spinal disc and spinal stenosis are common problems requiring decompressive spinal surgery. Traditional open spinal discectomy is associated with significant tissue trauma, greater morbidity/complications, scarring, often longer term of convalescence, and even destabilization of the spine. Therefore, the pursuit of less traumatic minimally invasive spine surgery (MISS) began. The tr...

AIM We conducted a novel classification system of degenerative lumbar spinal stenosis (DLSS) based on clinical manifestations and imaging (computed tomography and magnetic resonance imaging) features. We chose different minimally invasive surgical procedures according to our system. Clinical parameters and radiological findings will be assessed in the article. MATERIAL AND METHODS A retrospec...
