Laparoscopic mesh fixation using laser-assisted tissue soldering in a porcine model.

Background And Objective: Animal studies using open surgical models indicate that collagen solder is capable of fixation of surgical meshes without interfering with tissue integration, increasing adhesions, or increasing inflammation intraperitoneally. This study describes development of instrumentation and techniques for laparoscopic herniorrhaphy using laser-assisted soldering technology.

Study Design And Methods: Anesthetized 20 kg to 25 kg female Yorkshire pigs underwent laparoscopy with a 3-trocar technique.

Transabdominal preperitoneal herniorrhaphy using laser-assisted tissue soldering in a porcine model.

Background And Objectives: Collagen solder is capable of fixation of surgical meshes during laparoscopic herniorrhaphy without compromising tissue integration, increasing adhesions or inflammation. This pilot study describes development of instrumentation and techniques for transabdominal preperitoneal (TAPP) herniorrhaphy using laser-assisted soldering technology.

Methods: Anesthetized 20-kg to 25-kg female Yorkshire pigs underwent laparoscopy performed using a 3-trocar technique.

Pulsing influences photoradiation outcomes in cell culture.

Background And Objectives: Skin pigmentation can adversely affect phototherapy outcomes. Delivering pulsed light has been suggested as a means of enhancing efficacy. Suitable pulse frequencies remain indeterminate, often being selected empirically.

Melanin density affects photobiomodulation outcomes in cell culture.

Objective: This study investigated the influence of melanin on the outcome of photoradiation at 670 nm in a cell culture model.

Background Data: Melanins are naturally occurring cutaneous pigments. Human skin is classified into six skin types based on melanin content.

Histologic assessment of mesh fixation following laser-assisted tissue soldering in a lapine model.

Objective: Wound histology and mesh bioincorporation following intraperitoneal fixation using laser-assisted soldering was evaluated.

Methods: 2.8-3.

Preliminary assessment of postoperative adhesion formation after laser-assisted mesh fixation to the peritoneal surface.

Objective: This study evaluated the incidence and persistence of adhesions following intraperitoneal onlay mesh fixation with tissue soldering in an experimental model.

Methods: Anesthetized New Zealand white rabbits (n = 21), weighing 2.8-3.

Preliminary assessment of the tissue effects of a 1.44-micron laser via direct fiber contact on soft tissue.

Background/objective: A new pulsed near-infrared laser was developed for incision of soft tissues. This article presents a preliminary investigation of the 1.44-micron laser.

Laparoscopic cholecystectomy during pregnancy.

Background: Cholecystectomy represents the second most common nonobstetric operation during pregnancy. Published guidelines for laparoscopic cholecystectomy (LC) have considered it to be contraindicated in the gravid patient. Several cases of successful LCs in the gravid patient have been reported recently.

Preliminary assessment of the Con-Bio laser in vivo.

A variety of lasers are available for the treatment of pigmented and vascular lesions. This paper presents our preliminary evaluation of the Q-switched 532 nm Con-Bio laser (Continuum Biomedical, Livermore, CA) in a murine model. Mice were anesthetized with intraperitoneal pentobarbital.

Ergonomics of medical lasers: operator's viewpoint.

Lasers are instruments that may enhance the surgeon's ability to perform surgery. Many medical lasers sit unused. Lack of use is associated with "user unfriendliness.
