Comparison between a novel knotless technique and the conventional single knot technique of laparoscopic radical prostatectomy by novice laparoscopists.

OBJECTIVES: This study aimed to investigate a novel knotless technique for novice laparoscopists in traditional laparoscopic radical prostatectomy. METHODS: We studied 68 patients who had a novel technique performed in laparoscopic radical prostatectomy (knotless group) and 89 who had the conventional single knot technique (single knot group). The operations were all performed by novice laparoscopists with experience of fewer than 100 cases of laparoscopic radical prostatectomy. Knotless suture of the dorsal vein complex was conducted using a barbed self-retaining suture with three bites at the same location. The knotless urethrovesical anastomosis technique was conducted using a unidirectional single running fashion with a barbed self-retaining suture. RESULTS: There were no significant differences in the estimated blood loss, complication rate, postoperative hospital stay, anastomotic leakage rate, continence at 6 months after surgery, and positive margin rate between the two groups. The mean anastomotic time (24.9 vs. 44.2 min), operative time (168.1 vs. 201.8 min), and duration of catheter placement (12.8 vs. 19.8 days) were shorter in the knotless group than in the single-knot group. CONCLUSIONS: The knotless technique of laparoscopic radical prostatectomy is a safe and effective procedure.

A knotless, one-haptic fixation of posterior chamber intraocular lenses: one-year results.

AIM: To assess the results of a modified technique for scleral fixation of a posterior chamber intraocular lens (IOL) in eyes which had deficient of posterior capsular support. METHODS: This retrospective study was comprised of ten patients with deficient posterior capsular support who underwent one-haptic fixation of posterior chamber IOLs, between February 2010 and October 2011. IOL as implanted with one haptic supported on the capsular remnant and the other haptic drawn into the sulcus by anchoring suture without a knot. All patients were evaluated for pre- and postoperative visual acuity, lens centration, intra-and postoperative complications. RESULTS: A knotless, one-haptic fixation of posterior chamber IOLs has successfully been performed on ten eyes. All cases had inadequate capsular support (i.e. a capsular tear ranged from 5 to 7 clock hours). The average age was 74.25±8.87y (SD). The average postoperative uncorrected visual acuity was 0.51 logMAR. Complications included hyphema in one eye, a mild inflammatory reaction in the anterior chamber in two eyes, and a transient rise in IOP in one eye. Neither IOL tilt nor dislocation was observed and there were no later complications. CONCLUSION: In the presence of insufficient capsular support, a knotless, one-haptic fixation of posterior chamber IOLs is a safe and viable option which reduces the operation time, and minimizes postoperative suture-related complications.

Tratamiento artroscópico de las fracturas avulsión de espina tibial anterior. Nueva técnica CrossFix con arpones BioSwivelock con FiberTape sin nudos: técnica quirúrgica / Arthroscopic surgery of anterior tibial avulsion fractures

Describimos una técnica quirúrgica sin nudos (Knotless) con arpones Bioswivelock con sutura FiberTape (Arthrex inc. Naples Florida) con técnica cruzada; denominándola técnica CrossFix para reducción y osteosíntesis artroscópica de las fracturas avulsión de espina tibial anterior, logrando reducción anatómica estable, mínimamente invasiva sin la necesidad de realizar la extracción del implante al final del tratamiento. Nuestra técnica es aplicable tanto en pacientes con inmadurez esquelética como en adultos ya que no daña la fisis o cartílago de crecimiento y no requiere una segunda intervención para el retiro del implante; combinando las ventajas de la fijación con suturas de alta resistencia FiberTape, con la tecnología de los implantes sin nudos.

We describe a new surgical technique without knots (knotless technique) with Bioswivelock anchor and FiberTape suture (Arthrex inc. Naples Florida) with crossing technique, calling it CrossFix technique for arthroscopic reduction and internal fixation of avulsion fractures of the anterior tibial tubercle, achieving anatomic reduction, stable, minimally invasively without the need for removal of the implant at the end of treatment. Our technique is applicable to both patients adult and skeletal immaturity as not damage the cartilage growth plate or fisis and does not require a second surgery to remove the implant, combining the advantages of fixation with high strength sutures like the FiberTape, with an implant technology without knots like Bioswivelock.
