The current standard treatment for rectal cancer is based on a multimodality approach with preoperative radiochemotherapy in advanced cases and complete surgical removal through total mesorectal excision (TME). The most frequent surgical approach is traditional open surgery, as laparoscopic TME requires high technical skill, a long learning curve, and is not widespread, still being confined to ...

Introduction: The endoscopic transsphenoidal approach for pituitary adenomas and other sellar lesions is quickly becoming the procedure of choice in their surgical management. The most common approach is binostril three-hand technique which requires a large exposure and subjects both nasal cavities to potential trauma. To reduce nasal morbidity, we employ a mononostril two-hand technique with t...

Uretero-ileal anastomotic stricture is a potentially serious late complication after ileal conduit formation, with a reported incidence of 3-9%. The standard management technique is open surgical revision of the anastomosis with reimplantation of the affected ureter. This is technically challenging and has potential significant morbidity for the patient. Advances in endourological techniques no...

BACKGROUND AND IMPORTANCE Applications of robotics to minimally invasive spine surgery have produced several benefits while sparing patients the morbidity of traditional open surgery. Minimally invasive spine surgery offers the advantages of less pain and less blood loss, along with quicker recovery and shorter hospital stays. The da Vinci robotic surgical system has recently been adapted to ne...

Microsurgery for lumbar herniated discs that require surgical intervention is a very successful and well-described technique, whether performed through more traditional "open" microsurgical retractors or through minimally-invasive "tube" retractors. Surgery for extruded lumbar disc fragments that migrate caudad or cephalad from the disc origin may typically require modifying the standard hemila...

laparoscopic technique in recent years has tremendously being used as a non invasive surgery to perform different operation in abdominal and thoracic cavities. this technique has been used from 1987 in different aspect of human surgery. in addition to diagnosis, biopsy, visualizing adhesion and neoplastic structure, recently cholecystectomy and ovariohysterectomy were also commonly being used a...
