Laparoscopic pyeloplasty is a first-line option for the management of ureteropelvic junction obstruction. It has a greater success rate than endopyelotomy and is associated with a shorter and less intense convalescence than open surgical pyeloplasty. The technique is well established and reproducible, although the procedure is more difficult in certain situations, such as after a previous pyelo...

PURPOSE To compare the effect of three different suturing techniques on astigmatism after deep anterior lamellar keratoplasty (DALK) in patients with keratoconus. METHODS In this retrospective study, 54 eyes of 54 patients with advanced keratoconus underwent DALK with three suturing techniques: single running, interrupted running, and combined interrupted and running. Postkeratoplasty astigma...

Tissue adhesives are effective and yield results comparable to those with conventional suturing of superficial, linear, and low-tension lacerations. The cosmetic outcome is similar; wound complications, such as infection and dehiscence, may be lower with tissue adhesives. Wound closure of superficial lacerations by tissue adhesives is quicker and less painful compared with conventional suturing...

Rupture of the pectoralis major muscle is relatively rare. The authors present two cases of chronic rupture in which direct suturing was not possible; reconstruction was possible using a bone-patellar tendon autograft. They conclude that this surgical technique may be useful in some cases of chronic ruptures of the pectoralis major muscle in which direct tendon suturing is impossible.

AIMS To compare blood transmission through nitrile, single and double layer latex glove materials in simulated needlestick injuries. METHODS Experiments involved nitrile, single and double layer latex gloves. A cutting suture needle was dipped into a specimen of blood and then immediately jabbed through the glove material into a cell containing saline. This process was repeated using the same...

Minimal access surgery has been generally accepted as a method of operating through a very small incision or no incision at all. Today, all abdominal and thoracic surgeries can be performed with laparoscopy. Intracorporeal knot tying is an advanced skill that involves a difficult process with a long learning curve. In particular, when the angle between the working instruments is narrow and the ...

BACKGROUND Five years ago, we presented 19 procedures employing two intrastromal purse-string sutures to treat hyperopic shift following radial keratotomy. Thirty-four additional procedures and longer follow-up are now presented detailing the task of rehabilitating these eyes. METHODS Fifty-three eyes of 53 radial keratotomy patients who were unhappy with their uncorrected vision and who were...

There has been great progress in robotic surgical technology in recent years. The aim of this study was to objectively quantify robot-enhanced dexterity. To evaluate three-dimensional monitoring and non-dominant hand maneuverability using the da Vinci Surgical System, five surgeons were asked to thread the needle through all 11 holes on the model with handling robotic instrument. Three types of...
